METHODS AND SYSTEMS UTILIZING DELAYED DILUTION, MIXING, AND FILTRATION FOR
PROVIDING CUSTOMIZED BEVERAGES ON DEMAND
10
FIELD OF THE INVENTION
The present invention is directed to methods and systems to provide consumers
(at home
or away from home) quantities of ready-to-drink beverages, especially brewed
coffee and tea and
coffee and tea drinks (lattes, cappuccinos, chal teas, etc.). The consumer may
customize a type
of selection of beverage and various characteristics thereof, based upon
his/her taste preferences;
the serving of ready-to-drink beverage will be provided to the consumer.
More particularly, the present invention is directed to a system in which
information is
collected from a consumer regarding certain type, quantity, taste and strength
preferences of the
consumer. The information collected will be used to customize a suitabie
beverage product(s) for
the individual consumer. The means for dilution of the beverage extract or
concentrate may be
linked to the information system so that an extract/concentrate (e.g., brewed)
may be diluted
according to a customized strength, thereby accommodate the consumer's
strength preferences.
The "delayed dilution" aspects of the present invention may be used to
accommodate the
individual consumer's taste preferences by utilizing multiple varieties of
specific types of beverage
(e.g., more than one selection of coffee and/or tea), as well as different
varieties or tea or coffee
(roast strength, grind selection, plant and/or bean variety) in the brewing
system. The "delayed
dilution" aspects may also be used to deliver varieties of beverage options by
using the undiluted
concentrate/extract to mix/dissolve other beverage compounds or flavors to
make chai-teas,
cappuccinos, lattes, etc., with minimal dilution to the final beverage. The
"delayed mixing" aspect
of the present invention may be utilized to accommodate consumers' taste
preferences by taking
separated selected extractions of the brew and diluting appropriate
fraction(s) in accordance with
the consumer's preferences. The "delayed fiitering" aspects of the present
invention may be
utilized to accommodate various consumer preferences by offering variations in
processing that
would impact various aspects of body and character to accommodate a wide range
of consumer
taste preferences.
By providing a high volume system for making ready-to-drink beverages and
dispensing
CA 02531245 2000-08-14
successive individually customized servings thereof, the invention is
particularly desirable in the
restaurant, (especially fast food) environments, as well commercial and
industrial settings (office
buildings, workplaces, hospitals, and the like, with large waiting areas
This invention may also be used in household environments where it may be
desirable to
make several different types of finished beverage products tailored to the
taste preferences of
several household members. Because these many variations may be made from
earlier, initial
brew(s), the variations of the same type of beverage (e.g., coffee vs. tea)
can be provided
immediately upon each individual selection.
BACKGROUND OF THE INVENTION
Much study has been given to the most satisfactory way to brew beverages such
as
coffee and tea and it is a fact that an excellent grade of coffee or tea can
be effectively ruined for
consumption by improper methods of preparation of the ready-to-drink product.
In general, a high
quality and most satisfying coffee or tea drink is obtained only when it
possesses fine
characteristic aroma, delicacy of characteristic flavor, and fullness of
characteristic body.
Also importantly, many consumers have come to appreciate the many various
options
available with respect to coffee and tea products (e.g., variations in
strength, varietal type,
creaminess, flavors) and there are a wide variety of coffee options (lattes,
espressos,
cappuccinos, etc.) and tea options (regular tea, creamy tea, chai-tea and
green teas). However,
especially in a commercial/industrial setting (e.g., restaurant, fast-food
industry, workplace,
hospitals), there are many hurdles (e.g., space, difficulty, time, and/or
inconvenience) to be
overcome in delivering, especially on demand, the preferred choice of beverage
to a wide range of
consumers.
Additionally, most individual households comprise family members with various
taste
preferences; heretofore, it has been, at best, cumbersome and bothersome to
address individual
preferences, and would require many different brewing cycles and many
different receptacles to
accommodate mixing of different fractions and types. It would be desirable to
employ one (or at
least a minimal number of) extracts in a single countertop station to
efficiently accommodate
various taste preferences, on demand, in a household environment.
One particularly preferred aspect of the present invention is coffee
beverages. Coffee
beverages comprise an aqueous solution of the water-soluble (and sometimes
insoluble)
constituents of the roasted and ground beans of the tree of the family
Rubiaciae. There are many
varieties of this plant, but the two having the most significance commercially
is Caffee arabica and
Caffea canephora (robusta).
Equipment for brewing beverages such as coffee, tea, and the like have
typically been of
the "single station" type, in which an empty carafe or pot is positioned on a
heating element below
2
CA 02531245 2000-08-14
a receptacle or brewing funnel which contains a measured quantity of dry
beverage-making
material, e.g. roast and ground coffee or tea leaves. Hot water is then passed
through the material
to extract the essential oils, flavor and body that make up the beverage, and
then drains
downwardly through an opening in the funnel into the pot or carafe. If and
when a second pot or
carafe of beverage is needed, the first must be moved to a separate heating
element or plate.
Although such prior beverage brewers work satisfactorily for making relatively
small
quantities of beverage, in restaurants and other commercial and institutional
establishments, there
is a continuing need for equipment to make large quantities of brewed
beverage, but be able to
instantaneously accommodate the taste preferences of a wide variety of
consumers; furthermore,
this equipment must be easy to use and relatively automatic so as not to
require an unreasonable
amount of personal attention during the brewing cycle. The needs of
restaurants, institutions and
other commercial establishments are of particular concern in regard to
equipment for brewing and
making an acceptable cup of coffee to an individual consumer, given the
limitations of space,
labor, and time.
Some currently available beverage brewing devices provide essentially
instantaneous hot
water to brew beverages in a short amount of time. These devices typically
have a hot water
reservoir which maintains a volume of water at a predetermined temperature. A
cold water fill tube
is attached inside the reservoir, with one end close to, but not abutting, the
bottom of the hot water
reservoir, of a separate cold water reservoir or basin positioned above the
heated reservoir. A hot
water discharge tube has one end positioned in the hot water reservoir near an
outlet zone
generally at the top of the hot water reservoir. Another end of the discharge
tube delivers hot
water transported through the tube to a beverage brewing substance in order to
produce a brewed
beverage concentrate.
In order to brew a beverage in a beverage brewing device as described above,
cold water
is poured into the basin. The cold water flows through the cold water fill
tube and accumulates at
the bottom of the hot water reservoir due to temperature variations between
the cold and hot
water. The hot water is displaced by the cold water and moves upwardly towards
the top of the
hot water reservoir, which is sealed by a cover, and through the hot water
discharge tube, Upon
being dispensed into a beverage brewing substance, the hot water and beverage
brewing
substance create a brewed beverage concentrate. (For examples of
representative instantaneous
hot water beverage brewing apparati, see U.S. 3,385,201 to Martin, U.S.
4,920,871 to Anson, and
U.S. 5,025,714 and U.S. 5,113,752, both to Brewer.)
Dilution of the brewed extract/concentrate is necessary in order to prevent
the brewed
extract/concentrate from being too strong as well as preventing an additional
manual step of
diluting the extract/concentrate after it has been brewed. Dilution of the
brewed concentrate is
achieved by feeding water from the basin to either the brewing funnel and
allowing it to pass
3
CA 02531245 2000-08-14
through the grounds/leaves or the area between the inner brewing funnel and
the outer brewing
funnel.
It is generally desirable to provide equipment which requires minimum
maintenance by
the employees. It is preferable to provide equipment which will make a
sufficient volume of brew
to meet the customer demands without over-producing, but in adequate
quantities which can be
replenished within a reasonable time with minimum attention by the employees.
Additionally, and
desirably, the equipment should usually be compact.
It is, therefore, desirable to provide a beverage-brewing system which will
allow a
consumer to customize their preferred variety of beverages from a virtually
endless selection of
possibilities; the system of the present invention will provide an
individually customized serving of
beverage delivered at the desired temperature and ready to drink.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of the present invention to provide an
improved system
for providing an individually customized brewed ready-to-drink beverages to a
consumer, in a wide

It is a further object of the present invention to provide a brewing system
for making
varieties of brewed beverages, in particular variety, body, character and/or
strengths as chosen
by multiple individual consumers with the system being easy to use, by the
consumer or other
individual (e.g., restaurant wait staff) obtaining the customized beverage.
Further, the
maintenance of the subject equipment requires only a small amount of personal
attention by the
owner/operator of the equipment.
A general object of the present invention is to utilize "delayed dilution" of
a concentrate
extract to provide a beverage brewing system which immediately (upon customer
selection)
provides selective dilution (based on individual consumer's selections) of a

the extract has been allowed to brew and held as an extract before dilution.
It is also a general object of the present invention to utiiize the undiluted
extract to mix and
dissolve other beverage compounds to make flavored coffees and teas ,
cappuccinos, lattes,
creamy coffees and teas, chai teas, green teas, and the like.
It is also a general object of the present invention to utilize aspects of
"delayed mixing"
andlor "delayed filtering" to accommodate various consumer preferences
regarding body
character and consistency of the finished beverage, especially coffee-type
beverages.
It is also a general object of the present invention to provide a brewed
beverage delivery
system which allows a consumer to select from various classifications of
beverages and
customize said selection according to that consumer's preferences.

that allows the
user to create a customized beverage formula and store the information on data
storage device
106. Suitable programs could be constructed using such programming languages
java, cgi script,
html, xtml, shtml, and the like.
It will be appreciated that with respect to system 100 as represented in Fig.
5 it is within the skill of
those in the art to design and build systems that share system resources and
reduce the
redundancy of system components. In such systems, for example, network 507
could employ a
single data storage device 106 that may, or may not, be located in physical
proximity to the
system component at which the user is currently located. Additionally, system
100 could employ a
single data director 104 to which all devices are connected to over network
507.
Another embodiment of the present invention is represented by Fig. 6 and
described in
detail below. The customizable beverage system 100 is contained within housing
608. A touch
screen display 602 located within housing 608 serves as both the input device
for the collection of
data from the system user and the output device for displaying information
relating to the user's
beverage selection. Touch screen 602 displays a series of Graphical user
Interfaces (GUI) 603
which serve to facilitate the collection and display of information between
the user and the
customized beverage system 100. Information may also be collected
electronically by system 100
through the use of a card reader 604 which reads information stored on
identification card 607. For
system users' who are visually impaired, or simply to further facilitate the
exchange of information,
microphone 606 can be utilized to input verbal commands to system 100 and
speaker 609 can be
utilized to communicate choices and other information to the user. Verbal
commands via
microphone 606 would be translated using speech recognition software into
instructions that could
be interpreted by customization director 104 (not shown).
With reference to the presently described embodiment the user would approach
system
100 and be presented with a standard welcome GUI 603. The information
displayed on the
standard welcome GUI could be either static, dynamic, or mixtures thereof. In
one embodiment of
the present invention the standard welcome GUI 603 displays current news,
weather and sports
information, in addition to information describing the types of customizable
beverages system 100
can provide. System use instructions may also be displayed on the standard
welcome GUI 603.
The user then activates System 100 by either touching touch-screen 602
displaying the
standard welcome GUI 603, inserting the user's identification card 607 into
card reader 604, or
alternatively vocalizing a session start command that would be picked-up by
microphone 606.
7
CA 02531245 2000-08-14
Following system activation, system 100 alters the display on touch-screen
display 602 from the
standard welcome GUI 603 to the beverage selection GUI 700.
Fig. 7 shows the beverage selection GUI 700. Beverage selection GUI 700
contains a
personalized greeting area 702 which displays information referring to the
current user. This
information could include the user's name, account information such as
remaining balance,
beverage selection suggestions based on previous consumption patterns and/or
predicted
beverage choice desires, and the like. Beverage selection GUI 700 also
contains additional data
display area 704 which can display a variety of information that may or may
not be associated with
the current user. For example, additional data display area 704 could display
an update of user's
financial portfolio, e-mail account information (i.e., new message status,
message sender, subject,
or alternatively the entire message), weather updates, news headlines, sports
scores, and the like.
The exact information content dispiayed may be selected by the user, by system
100 based on
previous and/or current experience with the user (e.g. demographic criteria,
beverage selection,
and the like), or a combination of the two_ Additional data display area 704
may also display
advertisements and other promotional information.
Beverage selection GUI 700 also contains predetermined beverage selection
icons and
labels 706 which correspond to standard beverage formulations. These standard
beverage
formulations may be displayed for every user, regardless of the time of
activation, or may be
alternated by system 100 depending on the time of day, season, weather, and
the like.
Alternatively, the predetermined beverage selection icons and labels 706 may
correspond to
beverage formulations saved by the current user, for example, the current
user's favorite
afternoon beverage choice. The saved beverage formulation may be located on
and accessed
from the user identification card, may be stored in a locai data storage
device, or may be located
on a remote data storage device that is accessed by system 100. Beverage
selection GUI 700
also displays a customization option icon and label 708 which when selected by
the user will
initiate activation and display of the customization GUI 800.
Figure 8 details a beverage customization GUI 800 which display information
corresponding to the design of a customized beverage. The beverage
customization GUI 800 may
optionally contain personalized greeting area 702 and/or additional data
display area 704.
Principally, the beverage customization GUI 800 displays one or more
customizable beverage
characteristic indicators 802 which correspond to a given beverage
characteristic which system
100 can adjust in conformity with the indicated preference of the system user.
Customizable
beverage characteristic indicators 802 comprises a customizable beverage
characteristic scale
804 which conveys the total degree of variability possible with the given
customizable beverage
characteristic (i.e., roast color, beverage strength, beverage temperature,
additional flavors, and
the like), and customizable beverage characteristic position marker 805 which
corresponds to the
8
CA 02531245 2000-08-14
current level of customizable beverage characteristic on the customizable
beverage characteristic
scale 804. The system user would, in the case of a touch-screen, touch that
portion of the
customizable beverage characteristic scale 804 that represents the desired
level of the given
customizable beverage characteristic. The beverage customization GUI 800 would
then update
such that the customizable beverage characteristic indicator 802 would reflect
the user's
preference by displaying the customizable beverage characteristic position
marker 805 over the
appropriate portion of the customizable beverage characteristic scale 804.
When the user has
finished formulating a customized beverage the user may either save the
customized beverage
formulation via selection of the save icon 806, or the user may have system
100 dispense the
beverage via selection of the dispensing icon 808. Upon selection of the save
icon 806 system
100 may transfer the programmed beverage formulation to any device capable of
storing the
customized beverage information. Optionally, the user may return to a previous
GUI through
selection of the return icon 810 which will prompt the system to display a
previous GUI, such as
the beverage selection GUI 700.
Another embodiment of the present invention is detailed in Figure 9 and the
corresponding
description below. System 100 is capable of dispensing both customized
beverages and
beverages with predetermined, non-customizable formulations. The beverage
variety is indicated
by the beverage variety indicator icon 902, which displays information
pertaining to a given
beverage choice. If a given beverage variety indicator icon 902 corresponds to
a beverage choice
that is customizable then one or more customizable beverage characteristic
indicators 802 will be
iocated in close proximity such that the user may customize the beverage. In
one embodiment of
the present invention the customizable beverage characteristic indicator 802
comprises two or
more discrete customizable beverage characteristic indicators 908 which
correspond to a
customizable beverage characteristic (i.e., roast color, beverage strength,
beverage temperature,
additional flavors, and the like). System 100 also allows the user to select a
non-customizable
beverage. Once the user has selected the desired beverage, and customized the
beverage if the
desired beverage choice corresponds to a customizable beverage, the beverage
may be
dispensed via depression of dispense button 906.
DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to various embodiments of the invention,
various
examples of which are illustrated in the accompanying drawings, wherein like
numerals indicate
corresponding elements throughout the views.
The present invention is directed to a system for the individual customization
of ready to
drink brewed beverage products for multiple consumers, as well as the
provision of the
customized ready to drink beverages after consumer input. The method of the
present invention
9
CA 02531245 2006-09-15
comprises three basic steps: collecting information from a consumer regarding
the consumer's
desires as to the type and character of beverage he/she desires at that point
in consumption; a
system linking the consumers choice of product to a beverage delivery system
which contains an
amount of extract/concentrate and areas in the beverage delivery system(s) to
accommodate, If
desired, one or more aspects of delayed dilution, mixing and filtration. The
system of the present
invention may optionally utilize (any or all) the aspects of delayed dilution,
"delayed mixing" and
"detayed filtration" to further increase the options of beverage detiverable,
on demand, to the
individual consumer based upon their preferences.
A. Definition
As used herein the terms "brewed beverage products" and "fresh-brewed beverage
products" refers to coffees and teas.
As used herein, the terms "extract" and "concentrate" are used
interchangeably, unless
where otherwise specified. Within the context of the present invention -
providing individually
customized beverages on demand to consumer - it does not matter whether an
extract or
concentrate is used. "Fresh brewed" extracts are certainly acceptable, but are
not required. In
one embodiment, the roast and ground coffee is contained in pods or sachets
that are inserted
into the brewing chamber. An example of this type of pod is the "K-Cup",
manufactured by Keurig.
Inc. and disclosed in U. S. Patent Numbers 5,325,765 and 5,840,189.
Additional varieties of beverage products may be made but when the "customized
variety-
on-demand" aspects oF the present invention are used (delayed dilution,
delayed mixing and/or
delayed filtration), a customized beverage product can be delivered, that used
either extracts or
concentrates as starting material. The terms "extract," "concentrate,"
"extract/concentrate," and
"concentrate/extract" includes "brews," concentrates, "toddies," infusions,
and the like.
The term "fresh-brewed" as used herein refers to beverage
concentrates/extracts which
have been extracted and held for a"hold-time" and no more than about 48 hours.
As used herein, "coffee beverages" include cappuccinos, espressos, lattes,
flavored
coffee beverages, creamy coffee beverages, and other coffee-based beverages
which are
derivatives and/or variants of the above.
As used herein "tea beverages" include tea, green teas, herbat teas, flavored
tea, chai
teas, and creamy teas, and other tea-based beverages which are derivatives
and/or variants of
the above.
As used herein the terms 'ready-to-serve beverage" and "ready-to-drink
beverage" are
used interchangeably to refer to beverage products that are in a ready-to-use,
consumable form,
and other coffee and/or tea-based beverages which are derivatives and/or
variants of the above.
CA 02531245 2000-08-14
They are made from coffee extracts or tea extracts and can also include dry
mixes, powders,
liquids, extracts, concentrates, and emulsions, in a wide variety of
formulations.
The term "beverage type" as used herein means coffee or tea.
The term "classifications" as used herein means characteristics or attributes
of certain
types of beverage and include temperature, strength, body (full or light),
roast (color or degree),
acidity, sweetness, bitterness, andlor mouthfeel.
The term "variety" means country of origin (grown) and/or specific grown
region (e.g.,
varietal), including harvesting and post-harvesting techniques within a given
species or a species
within a genus. The fineness of the grind exerts an influence on the (quality)
flavor as well as the
degree of extraction (quantity). Coffee beans useful in the present invention
can be either of a
single type or grade of bean or can be formed from blends of various bean
types or grades, and
can be undecaffeinated or decaffeinated. These high-grown-type beans are
typically referred to as
high grade coffees. Suitable high grade coffee having high acidity include
Arabicas and
Colombians characterized as having "excellent body," "acid," "fragrant,"
"aromatic" and
occasionally "chocolatey." Examples of typical high quality coffees are
"Milds" often referred to as
high grade Arabicas, and include among others Colombians, Mexicans, and other
washed Milds
such as strictly hard bean Costa Rica, Kenyas A and B, and strictly hard bean
Guatemalans.
The term "hold-time" means that period of time beginning with the onset of
brewing of the
extract and ending when dispensed to the consumer.
As used herein, the term "comprising" means that the various coffees, other
ingredients,
or steps, can be conjointly employed in practicing the present invention.
Accordingly, the term
"comprising" encompasses the more restrictive terms "consisting essentially
of' and "consisting
of."
All ratios and percentages herein are based on weight unless otherwise
specified.
B. Making the Beverage Extract/Concentrate
Almost universally, the extract is brewed by contacting the roasted and ground
coffee with
hot water at a temperature from moderately-below boiling to moderately-above
boiling, for a
predetermined brewing time, separating the extract (including the solutes)
from the insolubles, and
consuming the resulting beverage.
Brewing methods can generally be categorized in three broad groups: (1) single-
pass
infusions in which the water is percolated or pumped through the roasted and
ground coffee
(which may partially serve as its own filter) then filtered through a metal,
paper, or cloth sieve; (2)
percolation methods which recycle the extract through one or more volumes of
grind
consecutively, in either a co-current or counter-current flow, before the
extract is siphoned off at
the requisite strength; and (3) batch-slurry methods in which a fixed volume
of coffee is mixed with
11
CA 02531245 2006-09-15
a fixed volume of water in a brewing vessel, permitted to steep with or
without agitation, then
filtered or mechanically separated to produce the extract.
Systems providing brewed beverages, especially coffee or tea, have typically
been of the
"single station" type, in which an empty carafe or pot is positioned on a
heating element below a
receptacle or brewing funnel which contains a measured quantity of dry
beverage-making
material, e.g. ground coffee or tea leaves. Hot water is then passed through
the material to extract
the essential oils, flavor and body that make up the beverage, and then drains
downwardly
through an opening in the funnel into the pot or carafe. If and when a second
pot or carafe of
beverage is needed, the first must be moved to a separate heating element or
plate. Although
such prior beverage brewers work satisfactorily for making relatively small
quantities of beverage,
in restaurants and other commercial and institutional establishments, there is
a continuing need for
equipment to make large quantities of beverages which is easy to use and
relatively automatic so
as not to require an unreasonable amount of personal attention during the
brewing cycle.
A suitable method for brewing a tea extract useful in the system of the
present invention is
disclosed in U.S., 4,757,752 to Robbins (assigned to General Foods Corp.),
issued June 19, 1988.
Any extract/concentrate which is generally available can be used in the
practice of the
system of the present invention. In one embodiment, the roast and ground
coffee is contained in
pods or sachets that are inserted into the brewing chamber. An example of this
type of pod is the
"K-Cup", manufactured by Keurig, Inc. and disclosed in U. S. Patent Numbers
5,325,765 and
5,840,189.
A particularly preferred method of providing brewed beverages is to provide an
extract
and combine it with the "delayed dilution" aspect of the system of the present
invention. Either or
both of the "delayed mixing" or "delayed filtering" aspects of the present
invention can be
combined with said particularly preferred mode.
While several embodiments of the present invention have been illustrated and
described, it is
not intended to thereby limit the present invention. Rather, it will be
obvious to those skilled in the
art that various changes and modifications can be made without departing from
the spirit and
scope of the invention. It is intended, therefore, to cover in the appended
claims all such changes
and modifications that are within the scope of this invention.
The system of the present invention preferably offers customization of a
brewed beverage
based upon consumer selection. This is optionally provided by utilization of
delayed dilution,
delayed mixing, or delayed filtering (one, two or all three, in any order) of
a beverage extract.
C. Delayed Dilution
12
CA 02531245 2000-08-14
As used herein, the term "delayed diiution" refers to the aspect of holding
the brewed
(preferably fresh brewed) beverage (preferably coffee) extract for a minimum
period of about 5
minutes, preferably of about 15 minutes, more preferably of about 30 minutes.
In a preferred
mode, "delayed dilution" also refers to the aspect of holding the extract for
a maximum period of
time of about 48 hours, preferably of about 24 hours, more preferably of about
12 hours, most
preferably of about 6 hours.
On particularly preferred embodiment involves the use of fresh brewed coffee
extracts: In
this embodiment, the fresh brewed extract produced by the process of the
present invention has a
brew solids of less than about 10%, preferably less than about 5%, more
preferably less than
about 4%, most preferably less than about 3.5%. In a particularly preferred
embodiment of the
process of the present invention, the extract has a minimum brew solids of
greater than about
1.2%, preferably greater than about 1.5%, most preferably greater than about
2%.
It is important to recognize that a key aspect of one of the embodiments of
the present
invention allows customization of the preferred coffee just prior to
dispensing; there is no
predetermination of characters or strength as is seen with many automated
systems. The
"delayed dilution" aspect allows multiple servings of individually tailored
coffee to be prepared from
a minimum number of brew cycle(s), preferably one. Additionally, these
individually tailored
servings are dispensed on demand.
When coffee extracts are used, it is preferred that said dilution ratios will
be from about
zero (no dilution) to about 1:15 coffee/water, and can be easily varied,
utilizing currently available
methods, upon receiving the consumer's selection input regarding strength.
Also, the temperature
of the dilution water may be varied to accommodate individual consumer
preferences around
consumption temperature; there are several ways that this could readily be
accomplished, but one
preferred way would be to have two dilution lines; one for hot (170-200 F) and
one for cold (40-
80 F) water and coordinate their rate and flow to deliver the coffee to each
individual consumer at
their preferred temperature.
In the practice of one of the preferred embodiments of the present invention,
the weight
ratio of the extraction portion of water to dry, roast and ground coffee is
from about 5:1 to about
24:1; preferably from about 8:1 to about 13:1. When this amount of water is
used for (drip)
extraction, a relatively strong (meaning concentrated but not bitter) filtered
coffee extract is issued.
Normally, this extract will have a soluble solids content by weight of greater
than about 1.2%,
preferably 1.5%. The relatively strong filtered coffee extract is then diluted
with a sufficient amount
of dilution water to a preferred beverage concentration.
It is important to recognize that a key aspect of a preferred embodiment of
the present
invention allows selection of the preferred beverage type and classification
just prior to dispensing;
there is no predetermination of characters or strength as is seen with many
automated systems.
13
CA 02531245 2000-08-14
The "delayed dilution" aspect allows multiple servings of the same beverage
type in individually
tailored beverages to be prepared from a minimum number of brew cycles,
preferably one.
Additionally, these individually tailored servings may be dispensed, if
desired, on demand.
Clearly, this aspect of the system of the present invention imparts many
benefits to the
extract that result in a better final beverage for the consumer. For instance,
delaying dilution of the
extracted beverage removes the need to hold the beverage in a "consumption-
ready," i.e., "ready-
to-drink", state (e.g., diluted and at the preferred temperature). In the
undiluted state, the
beverage, particularly coffee, has less water and degrades at a slower rate.
Addibonally, the need
to heat or cool during holding is minimized.
Further, the undiluted extract takes up less space and can be more easily
surged in a
given physical geometry.
Employing the "delayed dilution" aspect of this present invention results in
many benefits
to the finished beverage; this ultimately results in less "too old" or "stale"
beverage being served.
In a particularly preferred embodiment of the present invention, the brewed
extract may be cooled
or refrigerated. It will be recognized by those skilled in the art that
cooling or refrigerating the
extract or concentrate will further increase maximum hold times that can still
maintain desirable
flavor attributes.
D. Delayed Mixing
In another aspect of the present invention, the beverage extract/concentrate
can be
automatically fractionated previous to initial, or a subsequent (if any)
dilution. By mixing various
fractions of the extract, the character and body of the resulting beverage can
be changed. For
example, in coffee, the early fraction will be more acid, "high grown" and
less ashy and dirty. The
later fractions will be less acid and stronger in bitter ashy dirty flavors.
To accommodate various
consumer preferences, the coffee beverages could be made from the earlier
extract alone, the
latter extract alone, or a mix of fractions in various ratios. The potential
variety created could
cover "high grown" to "low" coffees and could also cover some of the aspects
character and body
resulting from a degree of roasting_
As used herein, the term "delayed mixing" refers to the aspect of holding the
brewed
(preferably fresh brewed) beverage (preferably coffee) extract for a minimum
period of about 5
minutes, preferably of about 15 minutes, more preferably of about 30 minutes.
In a preferred
mode, "delayed mixing" also refers to the aspect of holding the extract for a
maximum period of
time of about 48 hours, preferably of about 24 hours, more preferably of about
12 hours, most
preferably of about 6 hours.
It is recognized that novel beverage products could be prepared using this
aspect of the
present invention. Clearly, some substances that result in character and body
appear in initial
14
CA 02531245 2000-08-14
fractions only (or appear in initial fractions and disappear upon continued
heating) while other such
substances appear in later fractions only. By mixing fractions and, further,
by mixing them in
various ratios, a multitude of beverage types can be prepared which have
heretofore been
unavailable using standard brewing equipment and practices.
E. Delayed Filtering
The "delayed filtering" aspect of the present invention would allow the
beverage
extract/concentrate to stay in contact with the coffee grounds or tea leaves
during holding of the
extract. While not wanting to be limited by theory, it is believed that the
grounds or leaves would
help absorb the reaction compounds during extract storage and would also
buffer the acids
created during storage. Filtering could also be customized at dispensing,
e.g., metal filter vs.
paper filter, and could also be in stages (e.g., coarse metal mesh, followed
by dilution, and then
paper filtering).
As used herein, the term "delayed filtering" refers to the aspect of holding
the
brewed (preferably fresh brewed) beverage (preferably coffee) extract for a
minimum period of
about 5 minutes, preferably of about 15 minutes, more preferably of about 30
minutes. In a
preferred mode, "delayed dilution" also refers to the aspect of holding the
extract for a maximum
period of time of about 48 hours, preferably of about 24 hours, more
preferably of about 12 hours,
most preferably of about 6 hours.
F. Customization Interface
1. System Interface
Because of the potential purchase cost, personal time investment, and fear of
negative
experience, consumers may find experimentation or the "trial-and-error'
associated with finding
their most desired type of beverage product to be unacceptable or unpieasant.
Many consumers
do not understand how the various options available with respect to beverage
products
corresponds to their own individualized taste preferences. Further
complicating this situation is
that, in a given location, literally dozens of options with respect to
beverage products might be
available for consumption.
It is, therefore, desirable to provide a method which will allow a consumer to
identify one
or more beverage products which that consumer has a statistically greater
chance of accepting
and enjoying from a taste preference standpoint than other available beverage
products. Ideally,
such a system should be simple to learn and use.
The method of the present invention comprises three basic steps: collecting
information
from a consumer regarding the consumer's desires as to the variety of beverage
they desire at
CA 02531245 2000-08-14
that point in consumption; a process linking the consumer's choice of beverage
product to a
holding area which contains an amount of brewed extract; and an area where the
dilution of the
beverage occurs at a ratio of water to brewed beverage extract that is
consistent with the
consumer's choice as to brew strength and variety. The system of the present
invention may
optionally utilize (either or both) the aspects of "delayed mixing" and
"delayed filtration" to further
increase the options of "brewed" beverage deliverable, on demand, to the
individual consumer
based upon their preferences.
2. Definitions
The term "variety creating systems/devices" as used herein refers to devices
and
processes that can transform one or more input materials into multiple
varieties of beverages.
Such systems and devices including delayed dilution means/systems; delayed
filtering
means/systems, and/or delayed filtration means/systems.
The term "customization interface", as used herein, refers to the non-human
vehicle which
transmits the information (e.g. consumer information, customization
information, and
customization recommendation) between the consumer and the beverage delivery
system. This
interface can be embodied in many ways, and the consumer may access the
customization
interface from a remote location.
The term "beverage delivery system" as used herein refers to the station,
apparatus,
device, equipment, or series thereof that is linked with the customization
interface and is,
optionally, equipped with "variety creating systems/devices" inciuding delayed
diiution
means/systems; delayed mixing means/systems, and/or delayed filtration
means/systems.
The term "customized selection identification" as used herein refers to the
process in
which, and the means by which, the customization interface or the beverage
delivery system
recognizes the consumer and is able to deliver ( in the case of the beverage
delivery system) or to
direct the delivery ( in the case of the customization interface) the
customized beverage to the
consumer. Suitable ways of identifying the consumer include, but are not
iimited to, personal
identification number (PIN) either communicated to the system via a keypad,
touchscreen, matrix
card, retinal scanner, thumbprint reader, or radio frequency identification
tags (RFID).
The term "consumer identification" as used herein refers to the process in
which, and the
means by which, the customization director or the ID device recognizes the
applicable consumer
preferences and is able to develop and determine the appropriate customized
beverage
accordingly. Suitable ways of identifying the applicable consumer preferences
include, but are not
limited to, personal identification number (PIN), username, pass code, and the
like which can be
communicated to the system via an input device or process, such as a keypad,
touch screen,
16
CA 02531245 2000-08-14
matrix card, retinal scanner, thumbprint reader, magnetic card readers, bar
codes, or radio
frequency identification tags (RFID), and the like.
The term " consumer" as used herein refers to any user of the system
interacting with the
customization director for the purpose of inputting a beverage option,
customization information,
customization recommendation, or receiving a beverage product. This individual
can be a chef,
clerk, customer, " wait staff', servers, etc., and the like. The consumer may
access the user
interface from a remote location, e.g. by phone, Internet, wireless
connection, or the like.
The term "customization information" as used herein the information delivered
by the
customization interface or the beverage delivery system providing an
individualized selection of
customized information regarding products, option, characteristic or beverage
products that has
been processed by the customization interface to be relevant to the individual
consumer.
The term "customization recommendation" as used herein is the information
determined
by the customization director to provide an individualized customized
recommendation regarding
products, option, characteristic or beverage products that has been processed
by the
customization director to be relevant to the individual consumer or consumer
preference(s). In
one embodiment customization recommendations will be based on past
interactions. In another
embodiment, the customization recommendations may include promotional and/or
seasonal
selections.
The system of the present invention can also allow individual consumers to
communicate
with the system so that their personal customized selections can be
accommodated by the
beverage delivery system. There are many ways that individual systems can be
developed to
achieve this aspect of the present invention; the examples discussed herein
are representative
only and are not intended to be limiting. Suitable ways of communicating with
the consumer
include, but are not limited to, voice, keyboard, Internet, touchscreen, and
conventional means
such as selectors, slide bars, buttons, and switches. By understanding what
individual consumers
desire either by certain key questions, sampling or direct taste questions the
system can deliver
consumers preferred taste and needs.
An individuals' desires can also be dynamic and changing over time and/or by
event or
experience, e.g. time of day, day of week, day of month, seasonal, occasion,
environment,
work/pleasure, mood, physical, mental, etc. Their desires can also evolve
based on
experimentation, experience, education, knowledge, lifestyle changes, and age.
The
customization interface can include this type of personal or historical
information as it processes
the consumer information, as well as incorporate demographical trends and
traits, and common
experiences as it processes consumer information. In another embodiment, the
customization
recommendation may include promotional and/or seasonal selections.
17
CA 02531245 2000-08-14
For example, as individuals age, they may choose to add supplements to their
customized
beverage (post menopausal women may want to add calcium). Beverage delivery
systems in
particular venues may offer special additives (e.g., health food stores in
health clubs may want to
add new product lines (like vitamins or mineral powders) as samples to
increase retail sales and
health clubs may offer rehydration support after workouts.
Additionally, the customization interface may be continually assimilating
available data to
increase customization capability and ongoing recommendations. In a
particularly prepared
embodiment of the system of the present invention, this type of information
and inputs are
continually monitored, updated, and refined, to changes and predicts options
tailored to individual
consumers; this aspect of information processing is Global Assimilator
Customization System.
In one preferred embodiment of the invention herein, the system uses
information around
consumer's task preferences to suggest particular retail beverages that the
consumer might try. In
one version of the aspect, a consumer could use the beverage system to sample
various retail
brands. Conversely, various retail brands could refer to, or otherwise be
associated with, certain
flavors or selections in the beverage supply system.
The system of the present invention must be equipped with sufficient and
suitable memory
function so that both of the consumer and the menu items can be accommodated.
This includes
product use and incidence and consumer selection and response. There are many
ways that
individual systems can be developed to accommodate this aspect of the present
invenfion; the
exampies discussed herein are representative only and are not intended to be
timiting. Suitable
embodiments of the memory functions of the system of the present invention can
include, but are
not limited to, central databases, system databases, portable databases
The system of the present invention can have a means for the customization
interface to
identify, i.e. recognize, individual consumers. This allows individual
consumers to go/retum to the
physical location(s) of the system(s) (either the customization interface or
beverage delivery
system) and transmit to the system(s) their desired beverage selection without
repeating the step-
by-step sequence of selection programming. These individual preferences may
also include time
and place based adjustments that are determined by past system use histories.
There are many
ways that individual systems can be developed to accommodate this aspect of
the present
invention; the examples discussed herein are representative only and are not
intended to be
limiting. Suitable ways of identifying the consumer include, but are not
limited to, personal
identification number (PIN) either communicated to the system via a keypad,
touchscreen, matrix
card, retinal scanner, thumbprint reader, or radio frequency identification
tags (RFID). In addition,
the system(s) can be pre-programmed, periodically programmed, and/or networked
to allow for
the individual consumers' identification and associated preferences to be
universally recognized
by all such systems.

CA 02531245 2006-09-15
One aspect of the present invention, schematicaliy depicted in Fig. 1, can be
understood
from the system 100 for delivering a customized beverage product to a
consumer, comprising: a
user interface 102; a customization director 104 in communication with the
user interface 102; a
data store 106 in communication with the customization director 104; and a
beverage delivery
system 109 in communication with the customization director 104. In another
embodiment of the
present invention, the system further comprises an identification device 108
in communication with
the customization director 104 and a consumer identifier 110.
The customization director 104, might comprise a set of executable
instructions such as
in the form of software, routines, programs; algorithms, code, logic and the
like, which would, inter
alia, facilitate the determination of customized beverage formulations.
In one embodiment of the present invention, the customization director 104 is
provided in
communication, such as via a token ring, Ethemet, telephone modem connection,
radio or
microwave connection, parallel cables, serial cables, telephone lines,
universal serial bus "USB",
Firewi~e Bluetooig, fiber optics, infrared "IR", radio frequency "RF" and the
like, or combinations
thereof, with the data store 106 and the user interface 102. The customization
director 104 may
be integrated into a beverage dispensing device, or in an alternative
embodiment might be hosted
or housed on a remote device. Remote devices may include other consumer
appliances, a
personal computer, or an external server located somewhere on the Internet.
in another embodiment of the present invention, the user interface 102 might
comprise a
computer, a personal digital assistant (PDA), a kiosk, a device with wireless
application protocol
programs (WAP) such as cell phone, auto computer or PDA, interactive TV, or an
Intemet
appliance, or the like, User interface 102 allows the user to interact with
the interactive system
100 and, as will be understood, can take any of a virtually unlimited number
of alternative audio,
visual andlor other communicative forms. In an exemplary embodiment, the user
interface 104
may comprise a computer system comprising a CPU, memory, a visual display
device and an
input means. Preferred input means comprise a keyboard/keypad or mouse or
other means of
input such as an input microphone with speech recognition input devices, touch
screen input
devices, and/or visual input utilizing a video camera. In the illustrated
embodiment, the user
interface 104 might comprise a computer connected to the Internet through a
communication link
120 and running a web browser such as Intemet ExploreTrfrom Microsoft Corp. or
Netscape
TM
Navigator from Netscape Communications Corp. An example of the consumer input
to be
provided by the consumer might comprise the desired temperature of the brewed
beverage, for
example, hot, warm or cold, or in an alternative embodiment, the input may
request an actual
temperature to be inputted. Additional areas of input may further include
beverage strength (i.e.
varying level of blackness), beverage size (i.e. container size), additives
such as cream, sugar,
milk, artificial sweeteners, flavors and the iike.
19
CA 02531245 2000-08-14
The beverage delivery system of this example can be a standard beverage
delivery
system known to one skilled in the art. Examples include single-pass infusion
systems,
percolation systems, and batch-slurry systems. In one embodiment of the
present invention, the
interactive system 100 is integrated into the beverage delivery system 109. In
another
embodiment, the interactive system 100 is separate from the beverage delivery
system 109.
In yet another embodiment of the present invention, consumers desiring a
customized
beverage are provided an identifier 110 such as an identification card,
password or number which
comprises any available identification device or protocol known to one skilled
in the art. Such
identification may comprise any combination of bar codes, radio frequency
identification tags,
data, chips, smart cards and the like. Various identification/identification
device combinations are
known to one skilled in the art, and may be employed by various embodiments of
the present
invention.
In another embodiment of the present invention, the identification device 108
comprises a
bar code scanner. Various bar code scanners are known to one skilled in the
art and include 1)
pen type readers and laser scanners, 2) CCD readers, and 3) camera based
readers. Pen type
readers include a light source and a photo diode that are placed next to each
other in the tip of a
pen or wand. To read a bar code, the user passes the tip of the pen across the
bars and the photo
diode measures the intensity of the light reflected back from the light source
and generates a
waveform that is used to measure the widths of the bars and spaces in the bar
code. Dark bars in
the bar code absorb light and white spaces reflect light so that the voltage
waveform generated by
the photo diode is an exact duplicate of the bar and space pattern in the bar
code. This waveform
is decoded by the scanner. Laser scanners work the same way as pen type
readers except that
they use a laser beam as the light source and typically employ either a
reciprocating mirror or a
rotating prism to scan the laser beam back and forth across the bar code. As
with the pen type
reader, a photo diode is used to measure the intensity of the light reflected
back from the bar
code. In both pen readers and laser scanners, the light emitted by the reader
is tuned to a specific
frequency and the photo diode is designed to detect only this same frequency
light. Pen type
readers and laser scanners can be purchased with different resolutions to
enable them to read bar
codes of different sizes. The scanner resolution is measured by the size of
the dot of light emitted
by the reader. CCD (Charge Coupled Device) readers use an array of hundreds of
tiny iight
sensors lined up in a row in the head of the reader. Each sensor can be
thought of as a single
photo diode that measures the intensity of the light immediately in front of
it. Each individual light
sensor in the CCD reader is extremely small and because there are hundreds of
sensors lined up
in a row, a voltage pattern identical to the pattern in a bar code is
generated in the reader by
sequentially measuring the voltages across each sensor in the row. The
important difference
between a CCD reader and a pen or laser scanner is that the CCD reader is
measuring emitted
CA 02531245 2000-08-14
ambient light from the bar code whereas pen or laser scanners are measuring
reflected light of a
specific frequency originating from the scanner itself. The newest type of bar
code reader
currently available are camera based readers that use a small video camera to
capture an image
of a bar code. The reader then uses sophisticated digital image processing
techniques to decode
the bar code. Video cameras use the same CCD technology as in a CCD bar code
reader except
that instead of having a single row of sensors, a video camera has hundreds of
rows of sensors
arranged in a two dimensional array so that they can generate an image.
In another embodiment of the present invention, the identification device 108
comprises a
radio frequency scanning device. Radio Frequency Identification (RF ID) uses
radio frequency
communication to automatically identify, track and manage objects, people or
animals. A
low-frequency, passive, magnetically-coupled RF ID system is made up of two
parts: a reader and
a tag. The tags are typically attached to objects or animals that require a
unique identification
number. The tags include an electronic circuit (transponder) and tuned antenna-
capacitor circuit.
The tags are small sophisticated radio transmitters and receivers. They are
powered by the RF
field generated by the reader. Upon being powered up, the tag will
continuously transmit, by
damping the incoming RF power field, its data. The RF ID reader has three main
functions:
energizing, demodulating and decoding. The reader, using a tuned antenna-
capacitor circuit,
emits a low-frequency radio wave field. This is used to power up the tags. The
information sent
by the tag must be demodulated. The encoded information is decoded by the
reader's on-board
micro-controller. This information can then be used by a controlling
processor. In both the reader
and the tag, the antenna can be shaped and sized in different ways. Because of
the small size of
the tag, it can be formed to fit almost any situation. Since there is no
contact or viewing required,
the RF ID system allows great freedom of movement and placement of the tag and
reader become
less of a critical issue.
In one embodiment of the present invention, an administrative user may access
the
customization director 104 and data store 106 by utilizing an administrative
interface 130 to utilize,
analyze or otherwise apply the customization data and consumer feedback data
to develop or
improve products of the enterprise and to develop or improve components of the
beverage
brewing system. This insight gained from the consumer may also provide very
beneficial
information for the research, development, marketing and improvement of future
products and
systems. It can be contemplated as well, that an enterprise might make its
interactive data store
results and analysis of the data available to other entities. This might
entail allowing such entities
to have access to such data via the Internet, via printed reports, via
interactive software on
computers, periodic data subscription services or the like.
In yet another embodiment of the present invention, the system may further
comprise a
retail interface 180. The retail interface may be adapted to communicate
purchase data and
21
CA 02531245 2000-08-14
consumer data to and from the customization director 104. For example, a
consumer may make a
purchase for a beverage at a cashier checkout, but the beverage system may not
be directly
accessible from the checkout. The retail interface 180 may send data to the
customization
director 104 which will then prepare the beverage upon interaction by the
purchaser. In another
embodiment, the retail interface 180 communicates with the customization
director 104 to ensure
that the consumer is authorized to receive the beverage product. For example,
a consumer may
purchase the beverage from a remote locate and then enter a special access
code at the user
interface which then dispenses the beverage to the consumer.
There can be a number of ways to determine relevant customized brewing
formulations of
the beverage delivery system. In one embodiment, the consumer is prompted to
enter consumer
preference data through the user interface. This data may then be stored for
iater retrieval during
subsequent visits to the beverage delivery system. As an example, the consumer
preference data
inputted through the user interface or retrieved from the data store might be
matched against one
or more decision trees. A decision tree typically comprises a set of
responses/traits/categories
against which the consumer preference data can be compared against. For
example, a decision
tree might comprise every combination of possible consumer preference data.
The preference
data is then compared against the decision tree for a matching branch and the
matching branch
provides further instructions to be executed as a result of the match. Such
decision trees would
preferably comprise potential combinations of consumer preference data which
have been
designed with the system's intended application in mind, so that appropriate
optimized operating
conditions can be established that pertain to the customized beverage to be
delivered. Preferably,
the decision trees are converted to mathematical algorithms which then process
the decision tree
comparisons or "decisions" electronically to quickly ascertain the appropriate
optimized beverage
formulation for the beverage delivery system.
In order to update the optimization process to allow for modification or
"morphing" as
appropriate, one embodiment of the present invention comprises the decision
trees or algorithms
of the customization director 104 being updated by a neural network 111. In
the customized
beverage (Jelivery example, the neural network 111 would assess various
applicable consumer
preferences and feedback data retrieved from the data store to determine if
any changes to the
mathematical algorithms or dialog scripts are needed to facilitate or optimize
the decision making
process of determining customized beverage formulations. For example, a neural
network can
continuously update its decision making algorithm by incorporating user input
such as feedback
into the decision making process akin to artificial intelligence or "smart"
logic. According to
Haykin, S. (1994), Neural Networks: A Comprehensive Foundation, NY: Macmillan,
p. 2, a neural
network is a massively parallel distributed processor that has a natural
propensity for storing
experiential knowledge and making it available for use. It resembles the brain
in two respects: 1)
22
CA 02531245 2006-09-15
Knowledge is acquired by the network through a learning process; and 2)
Interneuron connection
strengths known as synaptic weights are used to store the knowledge. The
neural network
analyzes the data store 106 for trends, feedback data, consumer preference
data and other
additional data to develop and refine algorithms for decision making. In one
embodiment, a neural
network would automatically make changes to the customization director's 104
decision trees or
algorithms based upon the growing base of consumer preference and user
feedback data.
Another embodiment of the present invention, depicted in Fig. 2, includes the
method for
providing a customized beverage product to a customer. The method comprises
the steps of
obtaining consumer preference data corresponding to a customer (step 200);
determining a
consumer beverage formulation corresponding to the consumer preference data
(step 204); and
providing the consumer a customized beverage corresponding to the consumer
beverage
formutation (step 206).
The system of the present invention can also allow individual customers to
communicate
with the beverage delivery system so that their customized selectfons can be
accommodated by
the beverage delivery system. There are many ways that individual systems can
be developed to
achieve this aspect of the present invention; the examples discussed herein
are representative
only and are not intended to be limiting. Suitable ways of communicating with
the consumer
include, but are not limited to, voice, keyboard, Internet, touchscreen, and
conventional means
such as selectors, slide bars, buttons, and switches, By understanding what
individual consumers
desire either by certain key questions, sampling or direct taste questions the
system can deliver
consumers preferred taste and needs. A customer's desires can also be dynamic
and changing
over time and/or by event or experience, e.g. time of day, day of week, day of
month, seasonal,
occasion, environment, work/pleasure, mood, physical, mental, etc_ Their
desires can also evolve
based on experimentation, experience, education, moods, health conditions,
knowledge, Iffestyle
changes, and age. The customization interface can include this type of
personal or historical
information as it processes the consumer information. as well as incorporate
demographic trends
and traits, and common experiences as it processes consumer information.
Additionally, the
customization interface may be continually assimilating available data to
increase customization
capability and ongoing recommendations. In a particularly prepared embodiment
of the system of
the preseni invention, this type of information and inputs are continually
monitored, updated, and
refined, to changes and predicts options tailored to individual consumers;
this aspect of
information processing can be accomplished by a neural network or other
technologies known to
one skilled In the art.

Fig_ 3 schematically illustrates a sample clienUserver network 300 which might
be
employed to implement an embodiment of the present invention. As one with
ordinary skill In the
art will readily appreciate, a client/server network is only one type of
network, and a variety of
other configurations, such as peer-to-peer connections, are also considered
networks. In a
ciient/server network, a plurality of nodes are interconnected such that the
various nodes send
and/or receive information to/from one another. As shown here, a server node
302 is
interconnected with a plurality of client nodes 314 using a connection 316
such as a token ring,
Ethernet, telephone modem connection, radio or microwave connection, parallel
cables, serial
TM TM
cables, telephone lines, universal serial bus "USB", Firewire, Bluetooth,
fiber optics, infrared "IR",
radio frequency "RF", or other wireless communications, and the like, or
combinations thereof.
A computer-readable medium, shown here as a CD ROM (318), holds information
readable by a computer, such as programs, data, logic, files, etc. As will be
readily appreciated,
computer-readable medium can take a variety of forms, including magnetic
storage (such as hard
disk drives, floppy diskettes, etc.), optical storage (such as laser discs,
compact discs, DVD's,
etc.), electronic storage (such as random access memory "RAM", read only
memory "ROM",
programmable read only memory "PROM", etc.), and the tike.
One embodiment of the present invention comprises the method for providing a
customized beverage product to a consumer, An exemplary embodiment is depicted
In the
flowchart of Fig. 4. In this example, the consumer has previously registered
with the beverage
system and has been issued an RF ID key tag to utilize the system. The
consumer passes the RF
ID key tag across the ID device area of the system (step 400). The ID device
activates the RF ID
tag and receives the customer identifier stored in the tag (step 402). This
customer identifier is
then passed to the customization director (step 404), which in tum searches
the data store for
consumer data corresponding to the consumer identifrer (step 406). The
consunier data is
retrieved and the customization director analyzes the data (step 408) and then
presents to the
consumer one or more customization options (step 410). In one embodiment, the
customization
director might also prompt the consumer to enter feedback data for the last
interaction and
beverage delivery with the system. In another embodiment, the customization
director may
present one or more promotional and/or seasonal option selections to the
consumer.
Customization options include but are not limited to strength, flavor, type of
bean (coffee),
temperature, and finishing options (cream, milk, etc.) The customization
director can also display
express formulations which enable the consumer to select the express
formulation and all other
decisions are automatically completed by the system. in one embodiment, the
consumer can
manually create and save customization options as express formulations to save
time and reduce
formulation errors for future beverage deliveries. Once the consumer has
inputted his/her
customization options (step 412), the customization director will analyze the
options (step 414)
24
CA 02531245 2006-09-15
and send corresponding commands to the beverage delivery system (step 416). In
addition, the
customization director preferably stores the selected customization options in
the data store in a
record corresponding to the consumer identifier.
In one embodiment, the customization director witt, during a later
interaction, prompt the
consumer to input feedback data corresponding to the previous beverage
formufation. For
example, the customization director may prompt the consumer to input a rating
of 1 to 10 on the
beverage product customized during the last visit. In another embodiment, the
consumer may
select to speak with a customer service representative and the customization
director will establish
a connection which places the consumer in communication with the customer
service person. In
yet another embodiment of the present invention, the customization director
will display previous
beverage purchases associated with the consumer's identification and prompt
the consumer to
enter feedback data or complete a survey regarding the previous beverage
purchases. The
consumer may receive a reward (Le. con, discount, etc.) for complete feedback
data.
In another embodiment of the present invention, the consumer can access the
user
interface to preselect his/her beverage preferences in advance from a remote
location. For
example, the system may comprise numerous customization formulation options
whereby the
desired formulations could be customized ahead of actual purchase to save
time. In an exemplary
embodiment, a web site might be hosted on a network such as a wide-area
network, local-area
network, or the Internet, and the like, which the consumer can access through
some
communications device. The web browser contacts a web server and requests data
information,
in the form of a Uniform Resource Locator (URL). This data information
comprises the user
interface of the interactive system of the present invention. Typically, URL
addresses are typed
into the browser to access web pages, and URL addresses are embedded within
the pages
themselves to provide the hypertext links to other pages. A hypertext link
allows the user to click
on the link and be redirected to the corresponding web site to the URL address
of the hypertext
link. Many browsers exist for accessing the World Wide Web, such as Netscape
NavigatoMfrom
Netscape Communications Corp. and the Internet Explorer from Microsoft Corp.
Similarly,
numerous web servers exist for providing content to the World Wide Web, such
as Apache from
the Apache Group, Internet Information Server from Microsoft Corp., Lotus
Domino Go Webserver
from IBM, Netscape Enterprise Server from Netscape Communications Corp. and
Oracle Web
Application Server from Oracle Corp. These browsers and web servers can be
utitized to allow
access to the present invention from virtually any web-accessible device.
In another embodiment of the present invention, the system is configured to
communicate
with a remote data store. This ability allows the customization director to
identify individual
customers who have not previously interacted with the system at the present
location and to
retrieve the consumer's centrally-stored profile. This allows individual
consumers to go to various
CA 02531245 2000-08-14
physical locations of the system] and transmit to the system their desired
beverage selection
without repeating the step-by-step sequence of selection programming. These
individual
preferences may also include time and place based adjustments that are
determined by past
system use histories. There are many ways that individual systems can be
developed to
accommodate this aspect of the present invention; the examples discussed
herein are
representative only and are not intended to be limiting. Suitable ways of
identifying the consumer
include, but are not limited to, personal identification number (PIN) either
communicated to the
system via a keypad, touchscreen, matrix card, retinal scanner, thumbprint
reader, or radio '
frequency identification tags (RFID). In addition, the system(s) can be pre-
programmed,
periodically programmed, and/or networked to allow for the individual
consunmers' identification
and associated preferences to be universally recognized by all such systems.
EXAMPLES
While particular embodiments of the present invention have been illustrated
and
described, it would be obvious to those skilled in the art that various other
changes and
modifications can be made without departing from the spirit and scope of the
invention.
Example 1
Consumer establishes a personal profile over the Intemet or at the system and
answers a
few simple questions around beverage and related preferences. These questions
help deliver the
product with the right profile, and may allow the system to make suggestions
and/or formulation
modifications appropriate for the user during the instant or future
transaction. The profile is
maintained in a central database accessed by the system via wireless, local
area network (LAN)or
telephony communication devices wherever the consumer is. The consumer is
recognized via a
personal identification number (PIN) stored in radio frequency identification
tags RFID, matrix
cards, or their credit card. Consumer can get their own designed drink or
choose from a variety of
drinks that are close to their prescribed beverage in personal acceptance.
Consumer is allowed to choose from flavor profile of different atiributes in
creating their
own cup. This is done with slide bars and selectors or a multidimensional
space representing the
world of beverage taste including strength, sweetness, creaminess, and flavor.
User selects at various times the character of the coffee they prefer via an
consumer
interface window.
The consumer establishes a personal profile over the Internet or at the system
which may
entail and answering a few questions about beverage preferences. The responses
to these
questions are analyzed by the customization director to formulate and deliver
the product with the
right profile. The consumer is presented the opportunity to customize their
own beverage or
26
CA 02531245 2000-08-14
choose from a variety of pre-configured drinks that approximately match the
consumer's personal
profile.
In one embodiment of the present invention, an administrative user may access
the
customization director 104 and data store 106 by utilizing an administrative
interface 130 to utilize,
analyze or otherwise apply the customization data and consumer feedback data
to develop or
improve products of the enterprise and to develop or improve components of the
beverage
brewing system. This insight gained from the consumer may also provide very
beneficial
information for the research, development, marketing and improvement of future
products and
systems. It can be contemplated as well, that an enterprise might make its
interactive data store
results and analysis of the data available to other entities. This might
entail allowing such entities
to have access to such data via the Internet, via printed reports, via
interactive software on
computers, periodic data subscription services or the like.
In yet another embodiment of the present invention, the system may further
comprise a
retail interface 180. The retail interface may be adapted to communicate
purchase data and
consumer data to and from the customization director 104. For example, a
consumer may make a
purchase for a beverage at a cashier checkout, but the beverage system may not
be directly
accessible from the checkout. The retail interface 180 may send data to the
customization
director 104 which will then prepare the beverage upon interaction by the
purchaser. In another
embodiment, the retail interface 180 communicates with the customization
director 104 to ensure
that the consumer is authorized to receive the beverage product. For example,
a consumer may
purchase the beverage from a remote locate and then enter a special access
code at the user
interface which then dispenses the beverage to the consumer.

Example 9
In this example, an exemplary interaction with the customization director will
be described.
The consumer, Frank, approaches the user interface and slides his beverage
card through the
5 card reader which is part of the user interface. Frank previously had
completed an application for
the beverage card and was subsequently sent his own beverage card. Frank's
beverage card
contains a unique identification number that is utilized by the customization
director to retrieve
Frank's profile. In this example, Frank had previously chosen a
password/passnumber to protect
unauthorized use of his beverage card. Upon swiping his card through the card
reader, the
customization director through the user interface prompts Frank to input his
password. Frank
inputs his password through the touch screen display of the user interface.
The customization
director transmits the identification number and password to the data store to
determine if they
matched an existing record. Finding a match, the customization director
retrieves Franks
customization profile and analyzes the profile to determine the beverage
options to display to
Frank. The customization director displays numerous customization options to
Frank such as
coffee been type, temperature, strength, finishing options as well as a few
express options such
as your last coffee purchase, store's special pick and beverage of the month.
Frank then inputs
the selection of the special of the month. The customization director receives
Frank's selection
and determines the corresponding commands to send to the beverage delivery
system. The
beverage delivery system receives the commands and delivers the selected
beverage to Frank.
The customization director records Frank's beverage purchase in the data
store.
Example 10
In this example, another exemplary interaction with the customization director
will be
described. A typical consumer, Alice, approaches the user interface to
customize a beverage
purchase. Alice has never used the customization system before and has not pre-
registered her
preferences. The user interface prompts Alice to enter her user ID number or
select "NEW' if the
consumer is new. Alice selects "NEW' on the touch screen of the user
interface. The
customization director receives the "NEW' selection and determines which
selection options to
present to Alice. The customization director presents various customization
options to Alice
through the user interface. Some of the options include express
recommendations, formulation
options and a registration option. The registration option contains various
input areas for the
33
CA 02531245 2000-08-14
consumer to enter his/her preference data. The customization director then
creates a new record
for the consumer in the data store and associates the record with a new user
identification
(number, password, and the like). This new identification is then dispiayed to
the user and
preferably is sent to the user through an additional means. In this example,
Alice chooses the
formulation options and is asked to select the type of bean. Alice selects her
desired bean type
and then is prompted by the customization director to enter the desired
temperature range of the
beverage. Alice then selects some finishing options such as addition of cream
and sugar to the
formulation. The customization director then determines the corresponding
commands for the
beverage delivery system to produce the customized beverage. The customization
director sends
the commands to the beverage delivery system and records the customized
formulation in the
data store. The beverage delivery system receives the commands and produces
the customized
beverage for Alice.
