DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
100121 Figure 1 illustrates a fitness product 10 comprising a projection
display
assembly 11 that is arranged and configured in accordance with certain
features, aspects and
advantages of the present invention. While the illustrated fitness product 10
comprises a
group cycle, the fitness product 10 can be any cardiovascular and/or strength
related
equipment that uses a display. In some embodiments, the fitness product 10 can
be a
treadmill, a stationary bicycle, an elliptical exercise machine, a stair
climbing exercise
-2-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
machine or a weight training device, for example but without limitation. As
will be
explained, certain features, aspects and advantages of the projection display
assembly I I can
be used with any of a number of different types of fitness products 10 that
incorporate a
display.
100131 Preferably, the entire projection display assembly I I is affixed to
suitable
portion of the fitness product 10, such as a handlebar, a bracket, a handgrip,
a structural
beam, or other appropriate portion. The illustrated fitness product 10
comprises at least one
frame member 12 that in a preferred configuration supports the entire
projection display
assembly 11.
100141 The projection display assembly I1 generally comprises a projection
surface 14 and an image source 16. Accordingly, the frame member 12 preferably
defines a
portion of the fitness product 10 that supports the projection surface 14 and
the image source
16 of the projection display assembly 11. As shown, the projection surface 14
is spatially
separated from, but optically connected to, the image source 16. In some
configurations, the
frame member 12 is an intermediate or middle member that physically connects
together the
image source 16 and the projection surface 14 and, in other configurations,
the frame member
12 supports an additional assembly that directly connects the projection
surface 14 and the
image source 16.
100151 In the illustrated configuration, a housing 20 secures together the
projection surface 14 and the image source 16 of the projection display
assembly 11 of Figure
I. Preferably, the display housing 20 mounts to the fitness product 10 and can
be
permanently or removably affixed thereto. In particular, the housing 20
containing at least
the image source 16 can be secured to the frame member 12 of the fitness
product 10.
Accordingly, the housing 20 can comprise the additional assembly mentioned
above.
100161 The housing 20 preferably defines a waterproof housing. In some
embodiments, the housing 20 is sized, configured and located to reduce the
ability of sweat
from a user to infiltrate the housing and also protects the image source 16
from dirt, dust,
steam, vapor, mist, cleaning solutions and the like. Thus, the housing 20
defines a protective
enclosure for at least the image source 16 and preferably the electronics that
are related to the
image source 16 while the projection surface 14 is positioned largely outside
of the housing
-3-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
20. In most embodiments, an interface between the projection surface 14 and
the housing 20
will not be sealed around the complete periphery of the projection surface 14
because the
projection surface 14 does not feature electronics commonly found in LCD or
LED monitors.
Therefore, any seal would, not have to exist around the complete periphery of
the projection
surface 14. Moreover, in some embodiments, at least one edge of the projection
surface 14 is
exposed and not covered with a housing.
100171 The housing 20 can also include provisions for holding or supporting
personal effects, such as beverages, keys, towels, cell phones, PDA, mp3
players, and the
like. The housing 20 also preferably provides a suitable amount of protection
for the display
assembly components from external forces, such as can occur when the fitness
product 10 is
moved, or a person or equipment bumps into the housing 20 or the fitness
product 10.
100181 While the illustrated projection surface 14 is mounted to the housing
20,
the projection surface 14 can be mounted separate of the housing 20. In such a
configuration,
the image source 16 and the related electronics are not directly coupled to
the projection
surface 14. Moreover, in such a configuration, no seal would be required
between the
projection surface 14 and the housing 20 that contains the image source 16 and
both the
projection surface 14 and the housing 20 would be separately mounted to the
fitness product
10.
100191 The housing 20 and, where separately mounted, the projection surface
14,
preferably are secured to a portion of the exercise device where sufficient
support and
stability is provided. When the projection surface 14 is separately mounted,
sufficient
support and stability generally can be found where there is sufficient
vibration isolation or
where relative movements between the projection surface 14 and the image
source 16, such
as movements associated with vibration of the exercise device or devices
attached thereto,
occur simultaneously, in-phase, proportionally, or in some other way so that
they can be
determined, minimized, and/or accommodated without significant apparent
movement
between an image on the projection surface 14 and the projection surface 14
itself. For
example, an upper portion of a treadmill frame assembly may have certain
movements that
are out of phase with movements proximate a running deck of the treadmill. In
other words,
the upper portion of the treadmill frame assembly may sway and the lower
portion of the
-4-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
treadmill proximate the running deck may vibrate during use. Thus, if the
image source 16 is
positioned on the lower portion of the fitness product 10 and the projection
surface 14 is
positioned on the upper portion of the fitness product 10, the projected image
may appear to
be moving relative to the projection surface 14, which can be unsettling and
difficult to read.
While it may be possible to dampen such movement, it is preferred to simply
mount the
display surface 14 and the image source 16 such that both components generally
move
together if they move at all. Securing the image source 16 and the projection
surface 14
together to the frame member 12 desirably decreases relative movement and
decreases the
likelihood of vibrations being out of phase between the image source 16 and
the projection
surface 14.
100201 With reference to Figure 2, a reflector 22 is shown. The reflector 22
can
comprise a reflective surface, such as an optical element relying on
reflection or refraction,
including mirrors or prisms, and the reflector 22 redirects the light
transmission into a new
direction. Suitable materials for reflectors include glass or plastic,
including but not limited
to rnetalized glass or plastic, as well as metallic and crystalline materials.
In some
embodiments, the reflector can be mounted onto another material, such as wood,
plastic,
metal, or the like.
100211 The reflector 22 enables a more compact display unit and, in some
embodiments, can be used to switch between multiple surfaces that can receive
the projected
images. Moreover, in some embodiments, the reflector 22 can be used to direct
light from
multiple image sources onto a single surface for presentation to a user and
multiple reflectors
can be used in some embodiments with a single image source or with multiple
image sources.
100221 The illustrated reflector 22 is secured to the housing 20 and the
reflector
22 is shown located after any lens that may form a portion of the image source
16. Other
locations for- the reflector 22 are possible. While the illustrated reflector
20 is secured in a
fixed relationship relative to the image source 16 and the projection surface
14, it is possible
to configure the reflector 22 to be pivotable between at least two positions
and among more
than two positions, if desired. For example, when positioned as shown in
Figure 2, the
output from the image source 16 is directed toward the projection surface 14.
If the reflector
22 were moved out of the beam from the image source 16, however, the image
would be able
-5-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
to be directed onto a different surface, such as a wall in front of the
fitness product 10. In
some embodiments, one or more reflectors 22 can be adjusted manually,
remotely,
electronically, automatically, by switch, actuator, or the like such that the
location of the
image can be repositioned.
100231 Depending upon the implementation, the image projected from the image
source 16 may need to be inverted from top to bottom to provide proper
presentation of the
image depending upon whether and how many times the image is redirected by
reflectors. In
some instances, the movement of the reflector 22 may activate a switch to
cause inversion of
the image. Any other suitable techniques for inverting the image also can be
used.
100241 Preferably, as with the image source 16 and the projection surface 14,
the
reflector 22 is secured to the housing 20. In some instances, the reflector 22
can be secured
to other components of the fitness product 10 keeping in mind a desire to
minimize relative
movements among the image source 16, the reflector 22 and the projection
surface 14 such
that movement of the image relative to the projection surface 14 can be
minimized. Thus, in
a preferred configuration, at least the image source 16 and the reflector 22
are mounted
together. In a more preferred configuration, the image source 16, the
reflector 22 and the
projection surface 14 are mounted together. In an even more preferred
configuration, the
image source 16, the reflector 22 and the projection surface are mounted to
the housing 20,
which is supported by the frame member 12 of the fitness product 10.
100251 As discussed above, the projection display assembly I1 generally
comprises the image source 16 that is optically connected to the projection
surface 14 while
the image source 16 is spaced apart from the projection surface 14. The image
source 16 can
have a number of different constructions.
100261 With reference to Figure 3, the illustrated image source 16 comprises a
light source 28 and an image creator 30. The light source 28 can be any
suitable light
emitting technology, such as LED, halogen, fluorescent, incandescent, or the
like. Moreover,
the light source 28 can result in a display assembly I 1 that is
monochromatic, single colored
or multicolored. The light source 28 shines through the image creator 30 to
create an optical
image.
-6-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
100271 In some embodiments, the image creator 30 can create a visual
representation of an image by blocking or transmitting light. The image
creator 30 preferably
is dynamic and electronically controlled such that at least a portion of the
images created
relate to real-time activity on the fitness product 10. Any suitable technique
can be used for
the electronic control of the image creator 30. In some LCD components,
applying an
electric charge can vary the transparency of certain regions of the LCD in a
controlled
manner. The change in transparency can be used to block the transmission of
light. Thus, in
some configurations, the image creator 30 can block or allow the transmission
of light to
create the desired image. In other words, the LCD component can generate clear
portions of
what is desired to be shown or can generate a negative image of what is
desired to be shown
by blocking the portions that represent what is desired to be shown. In
addition, in some
configurations, both positive and negative image generators can be used. Other
image
creators also can be used. For instance, in some embodiments, a reflective LCD
or a
transflective LCD can be utilized.
100281 The image creator 30 also can include image elements that are
permanently depicted, such as by introduction of pigmented, opaque, semi-
opaque, or
translucent materials onto a surface or into the body of the image creator, or
into or onto a
material used as an overlayer/underlayer or filter for the image creator 30.
In such a manner,
some portions of the display assembly 11 may present dynamic information while
other
portions of the display assembly l I can present static information or the
like and at least
some of the static information can be projected.
100291 A focusing lens 24 can be positioned between light source 28 and the
projection surface 14 in the embodiment of Figure 3. For example, the focusing
lens 24
generally is positioned between the image creator 30 and the projection
surface 14 so that the
projected image can be focused and clearly presented on the projection surface
14. The
focusing lens 24 preferably is used with certain light sources. In some
embodiments, the lens
24 or other suitable focusing system can be utilized to modify the image
quality on the
projection display 14. Suitable lenses 24 and focusing systems include those
which increase
the size of the image, decrease the size of the image, change the focus of the
image, and/or
serve to collimate the light directed from the light source 28. In some
embodiments, the
-7-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
lens/focusing system can be positioned between the light source 28 and the
image creator 30.
In some embodiments, the lens/focusing system can be positioned after the
image creator 30.
In some embodiments, the lens/focusing system can be positioned between the
light source
28 and the image creator 30 with a second lens/focusing system located after
the image
creator 30. Adjustable lens/focusing systems include those being mechanically
adjustable,
electronically adjustable, manually adjustable, and automatically adjustable.
Adjustable
lens/focusing systems can be controlled by software, hardware, mechanical
linkages, servos,
motors, and the like.
100301 In the configuration shown in Figure 3, the light source 28 emits light
32
that passes through the image creator 30 such that the resulting image beam 34
depicts the
image created in the image creator 30. In some configurations, the transmitted
light passes
through the lens 24, which focuses the image for display on the projection
surface 14. Of
course, in the configuration shown in Figure 2, the image beam 34 contacts the
reflective
component 22, which redirects the image for display on the projection surface
14.
100311 FIG. 4 is a schematic representation of another type of image source
16.
As shown, a projection assembly 50 can use any suitable image creator as a
light source 52.
For example, the projection assembly 50 can comprise a PicoP enabled embedded
projector,
which uses a PicoP display engine, a MEMS scanning mirror, multiple colored
lasers and a
display engine to generate displayable images. Such an image creator is
available from
Microvision. Other types of suitable projection assemblies 50 can include
holographic laser
projection systems, such as that available from LightBlue Optics, which turn
flat surfaces into
a laser touchscreen, and other microdisplay projection displays,
microprojectors,
rniniprojectors, DLP projectors, DLP pico projectors, including those with
Brilliantcolor
technology, and the like.
100321 In the assembly 50 shown in Figure 4, the light source 52, which emits
light coded by an imaging portion 54, is used to generate light used to
produce an image. The
light is directed by an image adjustment component 56, such as a MEMS mirror
or the like,
into a scanning pattern to create an image on the projection surface 14. As
mentioned, other
types of image creators can be used with the projection display assembly 11.

WO 2010/124267 PCT/US2010/032321
100331 With reference now to Figure 6, the projection surface 14 preferably
defines a portion of the projection display assembly 11. In particular, the
projection surface
14 defines a portion of a user interface component 60. The projection surface
14 can be
opaque, semi-opaque, translucent, semi-transparent, or any degree of
transparency suitable
for displaying the image projected from the image source 16. The projection
surface 14 can
be formed from one or more of the following: fabric, wood, plastic, metal,
fiberglass, glass,
lexan, and a variety of coated or frosted materials including glass, plastic,
lexan, acrylic, and
other materials suitable for reflecting, displaying or capturing transmitted
light. At least a
portion of the projection surface 14 can have a mirrored finish, a polished
finish, or a shiny
finish and, in some embodiments, at least a portion of the projection surface
14 can have a
dull finish, a matte finish, or a flat finish. In a preferred embodiment, the
projection surface
14 is non-ferrous. In other words, the projection surface 14 in a preferred
embodiment
greatly reduces the likelihood of static discharge of a user when they touch
the projection
surface 14 because the projection surface 14 is non-conductive.
(0034] In the embodiment of Figures 1 and 2, the projection surface 14
presents
images on an opposite side from which they are projected from the image source
16. In some
embodiments, a touchscreen layer 62 can be positioned on or over the
projection surface 14.
Such an embodiment is presented in Figure 6, wherein the user will interact
via the
touchscreen layer with buttons that are displayed on the projection surface
14. In such
embodiments, the touchscreen layer 62 generally will be used on concert with
information
projected onto the projection surface 14, the images or information preferably
are not
projected from the same side of the projection surface 14 as the user will
interact. In other
words, the projection surface 14, as a result of the touchscreen layer 62 or
the like, becomes
an active control panel for the fitness product 10 because an image of a
button or the like can
be displayed, accessed and operated as a control button for the related
fitness product 10.
100351 In some embodiments, a touchscreen separate from the projection surface
14 can be used. In some embodiments, both a separate touchscreen and a
touchscreen in
combination with the projection surface 14 can be used. Separate touchscreens
can be
located over the projection surface 14, so as to allow viewing through the
touchscreen, or
near the display, such as alongside or near an edge of the projection surface
14, or distant
-9-
CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
from the projection surface 14, such as in a separate unit in electronic,
radio, or optic
communication with another portion of the projection display assembly 11. In
some
embodiments, the image can be viewed by looking at the same side of the
projection surface
14 as the image beam impinges upon the projection surface 14, such as with the
holographic
light projection technology mentioned above.
10036] With reference still to Figure 6, a user input device 64 on the user
interface
component 60 can be provided to control the fitness product 10 and/or other
devices
integrated with or associated with the fitness product 10. The user input
device 64 can
comprise one or more switches, buttons, control knobs or the like which may be
located on
the housing 20 used for the projection display assembly 11 or in a separate
housing that may
or may not contain components of the projection display assembly 11. The user
input device
64 can be used to allow positioning of a cursor on the projection display
assembly 11 and/or
movement between views or windows, such as those that allow movement
up/down/right/left. In some embodiments, a rotary knob or screen-simulated
rotary knob can
be used. Other controls can include joystick, buttons, levers, and the like.
The user input
device 64 can comprise controls that provide start/stop capabilities, a "back"
function, an
"escape" function, a "reset" function or a "restart" function or the like.
10037] In some embodiments, the projection display assembly I I can receive
and
display information from more than one source, such as from the fitness
product 10 and
computers, cell phones, mp3 players, PDAs, stereos, televisions, television
receivers, cable
receivers, satellite box, video game console, DVD players, CD players,
stereos, radios,
memory cards, and the like. With some of these sources, the display assembly
11 can simply
allow content (e.g., music, videos) to be passed through from the device to
the projection
display assembly 11 or the fitness product 10. In addition, in some
embodiments, the
projection display assembly I1 can receive and display information from more
than one
fitness product. In some embodiments, the projection display assembly 11 can
provide
information related to an individual's exercise performance along with
information from a
coach, teacher, observer, or bystander and/or information related to other
individuals' exercise
performance.

CA 02759842 2011-10-24
WO 2010/124267 PCT/US2010/032321
100381 In some embodiments, the projection display assembly I1 can interface
with other display units, sensors, transmitters, computer device, or other
electronic devices to
depict additional image elements, modify image elements, or to display or
store data. In
some embodiments, the imaging portion can include image elements generated by
a
computer, controller or other electronic device. In some embodiments, the
imaging portion
can include image elements from more than one computer, controller or other
electronic
device. In some embodiments, at least some image elements can be generated by
software
and, in some embodiments, at least some image elements can be representations
generated
from pictures, movies, or files transferred or otherwise supplied to the
fitness product 10.
100391 In various embodiments, images and information that can be displayed
include any of three or more types of information: product settings (e.g.,
speed, elevation,
time); workout effort information (e.g., watts, calories burned, heart rate);
and entertainment
(e.g., music, videos, television). Thus, information and images can be
displayed relating to
performance, such as speed, energy output, duration of exercise session, type
of exercise
being performed, stage of exercise, calorie utilization, remaining time for
exercise session,
exercise plan, and the like. The displayable information also includes
information related to
a biological status of a person, such as a person performing exercise and/or a
person at rest,
including the person performing the exercise or another person and such
biological status can
include heart rate, V02, temperature, blood pressure, height, weight, and the
like. In some
embodiments, the information can be input through entries such as on a keypad
or
touchscreen, including the touchscreen display used as in connection with the
projection
surface 14, or can be electronically input to the fitness product 10 from
sensors or
transmitters located in appropriate locations and using suitable transmission
technologies,
such as radio, wire, and/or optical transmission technologies. Information can
be provided in
numeric form, word form, graphical form, audible form, video form or some
combination of
these forms.
100401 In some embodiments, information related to operation of the equipment,
such as instructions, training techniques, and adjustment, set-up, start-up,
settings to use,
exercise routine to follow, and demonstrations of the operation can be
displayed. In some
embodiments, training recommendations can be displayed.

WO 2010/124267 PCT/US2010/032321
10041] In some embodiments, the controls on the projection display assembly 11
can control settings for the fitness product 10, such as resistance, speed, or
other parameters
that a user might want to adjust. In some embodiments, the projection display
assembly 11
can include a computer or microprocessor, such as included within a projection
display
housing. In some embodiments, the projection display assembly I I can include
speakers
built into the projection display assembly 11 and/or attached externally and
the projection
display assembly 11 can include an audio output jack or another way of
communicating with
headphones. In some embodiments, the display of an external integrated device
can be
routed into the display of the projection display assembly 11. In some
embodiments, the
control of the external integrated device can be through a control panel or
touch screen of the
projection display assembly 11. In some embodiments, the projection display
assembly 11 or
the fitness product 10 can be controlled by the external device.
10042] With reference to Figure 5, the image presented to a user of the device
can
be switched from the projection surface 14 mounted in to the fitness product
10 to a
projection surface 80 that is positioned external or away from the fitness
product 10 or can be
adjusted such that the image is presented on both projection surfaces 14, 80.
Such an
external or disconnected projection surface 80 can be located at some distance
from the
fitness product 10. In some embodiments, the disconnected projection surface
80 can be a
dedicated device, such as a screen fabricated for use with or supplied with
the fitness product
10. In some embodiments, the disconnected projection surface 80 can be a
general-purpose
screen such as those used for displaying projected movies or transparency
images. In some
embodiments, the disconnected projection surface 80 can be another device, a
door, a wall, a
ceiling, a floor, a box, a piece of furniture, a sheet, a board, a window, a
curtain, or some
other structural, building, furniture, decorative, room, furniture, or
equipment feature as
desired. In some embodiments a fog, mist, or liquid surface can be utilized as
a screen as
well.
10043] The image source 16 can be pivoted such that the image from the image
source can be directed as desired. In such a manner, the images can be
directed to the
integrated projection surface 14 or to the disconnected projection surface 80
as desired by the
user. If the light source is collimated or uses a laser, for instance, then
the image will be in

focus regardless of the distance between the image source and the projection
surface 14, 80.
Otherwise, where necessary, the focusing lenses and techniques discussed above
can be used
to focus the images depending upon the projection surface 14, 80 being used.
[0044] With two or more possible projection surfaces 14, 80, different options
can
be provided for supplying images to the surfaces 14, 80. In some embodiments,
a beam
splitter can be incorporated into the projector display assembly I 1 in order
to simultaneously
utilize multiple projection surfaces while having only a single image source.
In some
embodiments, images from multiple image sources 16 can be combined onto a
single
projection surface or can be projected onto multiple projections surfaces,
with appropriate use
of multiple sub elements, such as imaging portions, lenses, reflectors, etc.
to allow the
combination of images.
[0045] In some embodiments, optical cables can be incorporated into the
design,
such as for routing light from a light source to an imaging portion or from an
imaging portion
to a lens, reflector, or projection surface. In some embodiments, optical
cables can be
utilized to route light or images at more than one point within the projection
display.
