DETAILED DESCRIPTION
1. INTRODUCTION
[0078] Before describing the invention in detail, it is to be understood that
this invention is not limited to
particular methods, rotary units, rotary mechanisms, devices, or systems,
which can vary. As used in this
specification and the appended claims, the singular forms "a," "an," and "the"
also include plural
referents unless the context clearly provides otherwise. It is also to be
understood that the terminology
used herein is for the purpose of describing particular embodiments only, and
is not intended to be
limiting. Further, unless defined otherwise, all technical and scientific
terms used herein have the same
meaning as commonly understood by one of ordinary skill in the art to which
this invention pertains. In
describing and claiming the invention, the following terminology, and
grammatical variants thereof, will
be used in accordance with the definitions set forth below.

[0079] The term "coaxially positioned" refers to objects that are positioned
relative to one another such
that they can rotate about a substantially coincident axis.

[0080] The term "fixed position" refers to objects that are positioned
relative to one another such that
they do not move separately from one another. In some embodiments, for
example, gear components
(e.g., sun gear components) are attached (e.g., integrally fabricated, bonded,
welded, adhered, or the like)
to rotational components, such that when the rotational components move in one
direction, the gear
components move in the same direction as the rotational components.

[0081] The term "counter-rotate" or "contra-rotate" refers to objects that
rotate in opposite directions
relative to one another. In some embodiments, for example, rotary mechanisms
include rotational
components that are configured to rotate in opposite directions.

[0082] The term "communicate" refers to the direct or indirect transfer or
transmission, and/or capability
of directly or indirectly transferring or transmitting, something at least
from one thing to another thing. In
some embodiments, for example, devices include housings having openings
through which hair, finger
nails, or the like can be transferred to contact implements within housing
cavities of the devices.

[0083] The invention relates to rotary units and rotary mechanisms that are
suitable for use in numerous
applications. Rotary units typically include rotational components that are
configured to rotate. In some
embodiments, for example, multiple rotary units are assembled in rotary
mechanisms such that
neighboring pairs of rotational components counter-rotate or contra-rotate
relative to one another during
operation of the rotary mechanisms. Rotational components generally include
one or more implements
that are structured to perform or effect one or more types of work as the
rotational components rotate
24


CA 02737322 2011-04-14

relative to one another in a given rotary mechanism. In certain embodiments,
implements are configured
to rotate and/or to effect the movement of other components as rotational
components rotate. The
representative embodiments described herein are intended to illustrate, but
not to limit, the invention.
Essentially any combination of components or portions thereof described herein
are optionally utilized or
adapted for use together in certain embodiments.

H. EXEMPLARY ROTARY UNITS
[00841 Figures 1 A-H schematically show a rotary unit or components thereof
according to one
embodiment of the invention. As shown, rotary unit 100 includes rotational
component 102, which
includes first gear component 104 disposed on a first side of rotational
component 102 (e.g., in an inner
region of the first side) and second gear component 106 disposed on a second
side of rotational
component 102 (e.g., in an outer region of the second side). As shown, the
first and second sides
substantially oppose one another. Gear components used with the rotary units,
rotary mechanisms, and
other applications of the invention typically include gear teeth. Any operable
gear tooth configuration
and/or type are optionally used in the rotary units, rotary mechanisms and
applications of the invention.
Second gear component 106 substantially defines gear structure receiving area
108, which is configured
to receive gear structure 110. Gear structure 110 includes support component
112 and third gear
components 114. Third gear components 114 are configured to operably engage
second gear component
106 such that when third gear components 114 rotate in a first direction,
second gear component 106 and
rotational component 102 also rotate the first direction. Third gear
components 114 are configured to
operably engage other gear components, such as a first gear component of
another rotary unit such that
when the other gear components rotate in a second direction, third gear
components 114, second gear
component 106, and rotational component 102 all rotate in the first direction.
Rotary unit 100 also
includes retaining mechanism 116 (shown as a wall or lip in this exemplary
embodiment) that is
structured to retain gear structure 110 at least partially in gear structure
receiving area 108. As further
shown in Figure 11, for example, in some embodiments during rotary unit
assembly retaining mechanism
116 is attached to rotational component 102, once gear structure 110 is
positioned in gear structure
receiving area 108, via attachment components 118 (e.g., which clip into
corresponding notches (not
within view) in rotational component 102 in this representative embodiment).

[0085] Rotary unit 100 also includes implements 120 shown as beads that can be
used, for example, as
part of a massaging device or the like. Essentially any implement (e.g.,
type(s) and/or number on a given
rotational component, etc.) is optionally adapted for use with the rotary
units of the present invention,
e.g., depending on the intended application of a given rotary unit.
Representative implements that are
optionally used include one or more of, e.g., a blade, a razor, a prong, a
peg, a claw, a tine, a chain, a



CA 02737322 2011-04-14

stake, a column, a pillar, an arch, a bracket, a gear component, a bristle, a
plume, an abrasive component,
an elastomeric component, a nail filing component, a nail buffing component, a
hair cutting component, a
massaging component, a post, or the like. Some exemplary implements 200-210
are also illustrated from
side elevational views in, e.g., Figures 2 A-F.

[0086] In addition, rotary unit 100 also includes drive mechanism component
receiving area 122 (shown
as a hole disposed through rotational component 102) that is configured to
receive a drive mechanism
component, such as a drive shaft or a portion thereof. Other exemplary drive
mechanism components are
described herein or otherwise known in the art.

[0087] Figures 3 A-G schematically illustrate a rotary unit or components
thereof according to one
embodiment of the invention. As shown, rotary unit 300 includes rotational
component 302, which
includes first gear component 304 extending from a first side, and second gear
component 306 on a
second side and substantially defining gear structure receiving area 308.
Rotary unit 300 also includes
gear structure 310, which includes third gear components 312 rotatably coupled
to support component
314. As also shown, gear structure 310 includes hole 316 that is structured to
align with drive mechanism
component receiving area 318 of rotational component 302, e.g., to receive a
drive mechanism
component, such as a drive shaft about which gear structure 310 and rotational
component 302 rotate.
[0088] Rotary unit 300 also includes a retaining mechanism that is configured
to retain gear structure
310 in position relative to rotational component 302 such that the components
can operably engage one
another during operation. The retaining mechanism of rotary unit 300 includes
groove or track 320
disposed approximately around gear structure receiving area 308 in rotational
component 302. In
addition, the retaining mechanism also includes projections 322 of gear
structure 310 that insert into
groove or track 320 such that gear structure 310 is retained and rotates
within gear structure receiving
area 308.

[0089] In some embodiments, the rotational components of the rotary units of
the invention include
implements that are configured to effect the movement of one or more other
components (e.g., propeller
components or the like) when the rotational components rotate and the
implements operably engage the
other components. To illustrate, rotational component 302 of rotary unit 300
also includes gear
component 324 that is configured to operably engage other gear components of
other components, e.g., to
effect rotation of those components when rotational component 302 rotates.

[0090] Figures 4 A-G schematically show another exemplary embodiment of a
rotary unit of the
invention. As shown, rotary unit 400 includes rotational component 402 that
includes first and second
26


CA 02737322 2011-04-14

surfaces that substantially oppose one another. First gear component 404 is
disposed on the first surface
of rotational component 402 and is configured to operably engage third gear
components of another
rotary unit. Second gear component 406 is disposed on the second surface of
rotational component 402
and substantially defines gear structure receiving area or cavity 408.

[0091] Rotary unit 400 also include gear structure 410, which includes support
structure 412 and third
gear components 414 rotatably coupled to support structure 412. Rotary unit
400 also includes a retaining
mechanism formed, in part, by groove or track 416 formed in rotational
component 402. Circular
projection 418 disposed on support structure 412 of gear structure 410 is
configured to fit within groove
or track 416 such that gear structure 410 is retained, yet permitted to
rotate, within gear structure
receiving area 408. As also shown, rotary unit 400 also includes implements
420 (shown as blades)
extending from a surface of rotational component 402.

[0092] Figures 5 A and B schematically illustrate a rotary unit according to
another exemplary
embodiment of the invention. As shown, rotary unit 500 includes rotational
component 502. First gear
component 504 extends from a first side of rotational component 502, while
gear structure 506 engages a
second gear component in a gear structure receiving area on a second side of
rotational component 502
and partially extends from the gear structure receiving area. Gear structure
includes third gear
components 508 rotatably coupled to support structure 510. Rotary unit 500
also includes a retaining
mechanism formed, in part, by groove or track 512 formed in the gear structure
receiving area of
rotational component 502. Circular projection 514 disposed on support
structure 510 of gear structure
506 is configured to fit within groove or track 512 such that gear structure
506 is retained, yet permitted
to rotate, within the gear structure receiving area of rotational component
502. First gear component 504
is configured to engage one or more third gear components of another rotary
unit. Third gear components
508 are configured to engage the second gear component in the gear structure
receiving area and a first
gear component of another rotary unit.

[0093] Figures 6 A-G schematically show a rotary unit or components thereof
according to another
representative embodiment of the invention. As shown, rotary unit 600 includes
rotational component
602. Rotational component 602 includes first gear component 604 on a first
side and second gear
component 606 on a second side. Second gear component 606 substantially
defines a gear structure
receiving area of rotational component 602. Rotary unit 600 also includes gear
structure 608 disposed
within the gear structure receiving area. Gear structure 608 includes third
gear components 610 rotatably
coupled to support component 612. Third gear components 610 are configured to
operably engage
second gear component 606 of rotational component 602 and the first gear
component of another rotary

27


CA 02737322 2011-04-14

unit or another gear component, such as a component of a drive mechanism or
the like. Gear structure
608 also includes hole or aperture 614, which is structured to align with
drive mechanism component
receiving area 616 of rotational component 602, e.g., to receive a drive
mechanism component, such as a
drive shaft about which gear structure 608 and rotational component 602
rotate. Rotary unit 600 also
includes a retaining mechanism that is configured to retain and permit gear
structure 608 to rotate within
the gear structure receiving area of rotational component 602. In particular,
support component 612 of
gear structure 608 includes partially circular indentation 618 and rotational
component 602 comprises
projection 620 (e.g., an elevated circular track or the like). Projection 620
is configured to at least
partially fit and move within partially circular indentation 618 to retain
gear structure 608 at least partially
within the gear structure receiving area when second gear component 606 and
third gear components 610
operably engage one another. In some embodiments, gear structures comprise
projections, such as
projection 620 and rotational components comprise the substantially or
partially circular indentation (e.g.,
a circular track or groove structured to receive the projection).

[0094] Rotary unit 600 also includes implements 622 that are rotatably coupled
to rotational component
602. As shown, rotatably coupled implements 622 include gear components 624
that are configured to
operably engage a corresponding gear component on a neighboring rotary unit
when the neighboring
rotary unit is disposed suitably proximal to rotary unit 600. In these
embodiments, during operation, as
neighboring rotary units counter-rotate relative to one another, rotatably
coupled implements, such as
implements 622 (e.g., shown as bristles suitable for a toothbrush, household
cleaning device, or the like)
also rotate. To further illustrate, rotary unit 600 includes gear component
626 that is configured to
operably engage rotatably coupled implements disposed on a neighboring rotary
unit.

Drive mechanisms are
typically configured to effect movement of at least the portion of the counter-
rotational mechanisms such
that the rotational components substantially simultaneously counter-rotate
relative to one another. In

37


CA 02737322 2011-04-14

some embodiments, for example, multiple rotary units are included as
components (e.g., rotational
components and counter-rotational mechanisms, etc.) of rotary mechanisms.

[0125] In some embodiments, rotary units are operably coupled to one another
via one or more shafts.
To illustrate one embodiment, Figure 17A schematically depicts rotary units
100 and drive mechanism
component 1702 (shown as a shaft) prior to assembly. As shown, gear component
1704 is fixedly
coupled to shaft 1702 and is configured to operably engage third gear
components 114 (not within view in
Figures 17 A and B) of a rotary unit 100 in assembled rotary mechanism 1700.
During assembly, shaft
1702 is inserted through drive mechanism component receiving areas 122 (shown
as holes, e.g., in Figure
1 A) of rotary units 100 to operably couple rotary units 100 to one another.
Figure 17B schematically
illustrates rotary units 100 and shaft 1702 following assembly. Suitable
shafts include a variety of cross-
sectional shapes (e.g., circular, oval, triangular, square, rectangular,
polygonal, etc.). In some
embodiments, a given shaft includes multiple cross-sectional shapes. In some
of these embodiments,
individual rotary units include drive mechanism component receiving areas
(e.g., holes, apertures, etc.)
that correspond to those different cross-sectional shapes. In some
embodiments, for example, one
member of a pair of neighboring rotary units includes a square hole that fits
on a square cross-section of a
shaft, while the other member of the pair includes a circular hole that fits
on a circular cross-section of the
shaft. In these embodiments, the rotary unit with the square hole typically
rotates in a substantially fixed
position relative to the shaft, whereas the rotary unit with the circular hole
typically rotates substantially
free or independent relative to the shaft.

[0126] To further illustrate, Figures 18 A-C schematically show rotary
mechanism 1800 assembled from
pairs of rotary units 700 and 800, which are both described further herein.
More specifically, Figure 18A
schematically shows an individual pair of rotary units 700 and 800 prior to
assembly of rotary mechanism
1800 from side views. Figure 18B schematically shows partially assembled
rotary mechanism 1800 with
the rotary units of Figure 18A from side views. Figure 18C schematically
illustrates rotary mechanism
1800 that includes multiple pairs of rotary units 700 and 800.

[0127] In some embodiments, rotary units are operably coupled to one another
via one or more shafts.
To illustrate one embodiment, Figure 19A schematically depicts rotary units
900, drive mechanism
component 1902 (shown as a shaft), and cap component 1903 prior to assembly.
As shown, gear
component 1904 is fixedly coupled to shaft 1902 and is configured to operably
engage or mesh with gear
components 914 of a rotary unit 900 in assembled rotary mechanism 1900. During
assembly, shaft 1902
is inserted through drive mechanism component receiving areas 925 (shown as a
hole, e.g., in Figure 9A)
of rotary units 900 to operably couple rotary units 900 to one another. Shaft
1902 operably connects with
38


CA 02737322 2011-04-14

cap component 1903 in assembled rotary mechanism 1900, e.g., to hold rotary
units 900 in position
relative to one another. Figure 19B schematically illustrates rotary units
900, shaft 1902, and cap
component 1903 following assembly of rotary mechanism 1900. The directional
arrows in Figure 19B
schematically depict that neighboring pairs of rotary units 900 in rotary
mechanism 1900 are configured
to counter-rotate relative to one another. Figure 19C schematically shows a
portion of a rotary
mechanism that includes rotary units 900 with implements 918.

[0128] Figures 20A-O schematically show a rotary mechanism or components
thereof according to
exemplary embodiments of the invention. As shown, rotary mechanism 2000
includes four rotary units
that each include rotational component 1302 and gear component 1304. Rotary
mechanism 2000 also
includes a drive mechanism that includes shafts 2002 and motors 2004. Motors
2004 are configured to
effect rotation of shafts 2002. As shown, the drive mechanism is configured to
effect rotation of gear
components 1304 such that rotational components 1302 of neighboring or
adjacent pairs of rotary units
rotate in opposite directions. See, e.g., the directional arrows in Figure
20H, which schematically depict
the counter-rotation of neighboring pairs of rotational components 1302. As
shown, one shaft 2002 is
operably connected to a first set of two non-neighboring gear components 1304,
while the other shaft
2002 is operably connected to a second set of two non-neighboring gear
components 1304 that is different
from the first set of two non-neighboring of gear components 1304. The two
shafts 2002 are configured
to rotate in opposite directions. See, e.g., the directional arrows associated
with shafts 2002 in Figures 20
H and I. As also shown, surfaces 1305 of rotational components 1302 are
configured to rotate
substantially non-perpendicular to a rotational axis of rotational components
1302.

[0129] Any suitable drive mechanism is optionally utilized with these rotary
mechanisms. For example,
Figure 20L schematically depicts a portion of a drive mechanism from a side
view. As shown, the drive
mechanism includes motor 2004 (depicted as a dual shaft motor) that is
configured to effect rotation of
shafts 2002 in opposite directions via meshing pairs of gear components 2006.
To further illustrate,
Figures 20M-O schematically depict portions of a drive mechanism. As shown,
motor 2004 is configured
to effect rotation of shafts 2002 in opposite directions via a gear train that
includes gear components 2008.
[0130] In addition, rotary mechanism 2000 also includes positioning component
2010 (shown as a frame
structure) that is configured to position rotary units relative to one
another. As shown, shafts 2002 are
positioned relative to positioning component 2010 via mount brackets 2012,
which permit rotation of
shafts 2002. As also shown, positioning component 2010 also includes a
plurality of friction reducing
materials 2014 (shown as roller balls) disposed on a surface of positioning
component 2010 to reduce
friction as rotational components 1302 rotates relative to positioning
component 2010. In the

39


CA 02737322 2011-04-14

embodiments in which friction reducing materials are utilized, essentially any
friction reducing material is
optionally adapted for use with the rotary mechanisms of the invention. Other
exemplary embodiments
include, for example, coatings (e.g., TEFLON , etc.), lubricants, surface
features, and/or the like. Figure
20G schematically depicts positioning component 2016 according to another
exemplary embodiment.

[0131] Figures 21A-E schematically show rotary mechanisms or components
thereof according to
exemplary embodiments of the invention. As shown, rotary mechanism 2100
includes drive mechanism
component 2102, which includes ring gear component 2104 and a gear structure.
The gear structure
includes support component 2106 and planetary gear component 2108 rotatably
coupled to support
component 2106. Planetary gear component 2108 is configured to operably engage
ring gear component
2104 of drive mechanism component 2102 and gear component 1410 of rotary unit
1400. Drive
mechanism component 2102 also includes motor 2110, which is configured to
effect rotation of ring gear
component 2104 via shaft 2112. Shaft 2112 is fixedly connected to ring gear
component 2104. When
ring gear component 2104 rotates, it effects the counter-rotation of
neighboring pairs of rotary units 1400
relative to one another. See, e.g., the directional arrows associated with
Figures 21 B and C, which
schematically depict the counter-rotation of neighboring pairs of rotary units
1400. As also shown, in
assembled rotary mechanism 2100, support component 2106 is operably connected
to support
components 1417 of rotary units 1400 such that support component 2106 and
support components 1417
are substantially fixedly positioned relative to one another when ring gear
component 2104 effects the
counter-rotation of neighboring pairs of rotary units 1400 relative to one
another. Gear structures that
include support components 1417 are described further herein. To further
illustrate, Figure 21D
schematically depicts rotary mechanism 2114, which includes rotary units 1400
with implements 1418.
In addition, Figure 21E schematically illustrates rotary mechanism 2116, which
includes rotary units 1400
with implements 1418 and dual shaft motor 2118.

[01321 The gear structures of the invention include various embodiments. To
illustrate, Figure 22A
schematically illustrates gear structure 1415 prior to assembly with another
gear structure 1415 from a
side view according to one embodiment of the invention. As shown, gear
structure 1415 includes support
component 1417 and gear components 1414 (e.g., planetary gear components or
the like), which are
rotatably coupled to support component 1417. Gear components 1414 are
configured to operably engage
or mesh with one or more other gear components when gear components 1414 are
disposed proximal to
the other gear components. During assembly, threaded region 1429 of one
support component 1417 is
inserted into threaded region receiving area 1427 of another support component
1417 such that the
assembled support components 1417 are substantially fixedly positioned
relative to one another when
rotational components 1402 of rotary units 1400 rotate relative to support
components 1417 and to one



CA 02737322 2011-04-14

another. Essentially any attachment technique is optionally utilized to attach
support components 1417 to
one another. Some exemplary techniques include, for example, bonding, welding,
adhering, or the like.
In some embodiments, multiple support components 1417 are fabricated as single
integral part (e.g., as a
molded part or the like). Figure 22B schematically shows an assembly of four
gear structure 1415 from a
side view. Figure 22C schematically depicts the gear structure assembly of
Figure 22B from a rear side
view, while Figure 22D schematically depicts the gear structure assembly of
Figure 22B from a front side
view.

[0133] To further illustrate, Figure 22E schematically shows rotary mechanism
2200 that includes the
gear structure assembly of Figure 22B from a sectional view according to one
embodiment of the
invention. As shown, rotary mechanism 2200 includes four rotary units 1400.
Counter-rotation of
neighboring rotational components 1402 in rotary mechanism 2200 is effected by
drive mechanism
component 2202, which includes shaft component 2204 and gear component 2206.
Figure 22F
schematically shows rotary mechanism 2200 from a side view. Rotational
components 1402 of rotary
units 1400 of rotation mechanism 2200 are configured to rotate relative to
support components 1417,
which support components 1417 are substantially fixedly positioned when
rotational components 1402
rotates relative to support components 1417. Gear components 1414 are
configured to rotate relative to
rotational components 1402.

[0134] Figures 23A-T schematically depict a rotational mechanism or components
thereof according to
one embodiment of the invention. To illustrate, Figures 23A and C, for
example, schematically depicts a
portion of rotational mechanism 2300 from an exploded side and exploded side
sectional views,
respectively. During assembly of rotational mechanism 2300, support component
1614 of one rotary unit
1600 is inserted through hole 1508 of rotary unit 1500 and threaded region
1632 of that support
component 1614 is received and retained in threaded region receiving area of
another rotary unit 1600.
[0135] Figures 23E-P schematically show a portion of a drive mechanism
component that is utilized to
effect counter-rotation of neighboring pairs of rotary unit 1500 and rotary
unit 1600 of rotational
mechanism 2300. As shown, the portion of the drive mechanism component
includes rotational
component 2302, which includes ring gear component 2304, hole 2306, and
implements 2308. The
portion of the drive mechanism component also includes gear structure 2310,
which includes support
structure 2312 and planetary gear components 2314 rotatably coupled to support
structure 2312. Support
structure 2312 also includes friction reducing materials 2316 (shown as
elevated or pointed surface
features) to, e.g., reduce friction between support structure 2312 and
rotational component 2302 when
rotational component 2302 rotates relative to support structure 2312. Support
structure 2312 also

41


CA 02737322 2011-04-14

includes threaded region 2318, which is received by a corresponding threaded
region receiving area of
fastener 2320 (e.g., a nut or the like) through hole 2306 to hold gear
structure 2310 in position relative
rotational component 2302, yet permit rotational component 2302 to rotate
relative to support structure
2312 and planetary gear components 2314. In addition, support structure 2312
also includes threaded
region receiving area 2322, which is configured to receiving thread region
1632 of a rotary unit 1600,
e.g., in assembled rotational mechanism 2300.

[0136] As also shown, a shaft 2324 is also fixedly connected to rotational
component 2302. Although
not shown, a motor or the like is typically operably connected to shaft 2324,
which effects the rotation of
shaft 2324 and the counter-rotation of neighboring pairs of rotary unit 1500
and rotary unit 1600 of
rotational mechanism 2300 (e.g., as schematically depicted by the directional
arrows shown, e.g., in
Figure 23S) during operation. In addition, a rotary unit 1600 also operably
connects to support
component 2326 via threaded region receiving area 1634 of support structure
1614, e.g., such that support
structures 1614 of rotary units 1600 and support structure 2312 of gear
structure 2310 are substantially
fixedly positioned when rotary units 1500, rotary units 1600, and rotational
component 2302 rotate
relative to one another in rotational mechanism 2300. Essentially any support
component is optionally
used. In some embodiments, support components are included in or as part of
devices, apparatus, or other
applications of the rotational mechanisms of the invention. Exemplary support
components and
applications are described herein.

IV. EXEMPARY APPLICATIONS
[0137] Figures 24 A and B schematically illustrate a rotor tiller or
rototiller that includes a rotary
mechanism according to one embodiment of the invention. As shown, rotor tiller
2400 includes rotary
mechanism 2462 that is operably connected to motor 2404 via shaft 2474. As
also shown, rotor tiller
2400 also includes wheels 2402 and handle 2406 coupled to a support structure.

[0138] To further illustrate exemplary embodiments of the invention, Figure
25A schematically shows
vehicle 2500 from a side elevational view. As shown, vehicle 2500 includes two
rotary mechanisms 2502
and grading blade 2503, which can each be independently raised and lowered.
Rotary mechanisms can
include various embodiments, including various types of implements (e.g., as
described herein or the
like). As also shown, vehicle 2500 also includes wheels 2504, driver's
compartment 2506, and engine
compartment 2508. Vehicle 2500 can be adapted for a wide variety of uses in,
e.g., agricultural,
construction, military, or other applications. In some embodiments, for
example, vehicle 2500 is used to
till, grade, and/or otherwise move soil. As another exemplary illustration,
Figure 25B schematically
shows vehicle 2501 from a side elevational view. As shown, vehicle 2501
includes rotary mechanism
42


CA 02737322 2011-04-14

2510, which can be raised and lowered. As also shown, vehicle 2501 also
includes wheels 2504, driver's
compartment 2506, and engine compartment 2508. Vehicle 2501 can be adapted for
a wide variety of
uses. In some embodiments, for example, vehicle 2501 is used to till, grade,
and/or otherwise move soil.
[0139] In other representative embodiments, the invention provides hair
cutting devices, e.g., for cutting
facial hair, leg hair, or hair on other body parts. To illustrate, Figures 26
A-G illustrate various aspects of
a hair cutting device according to one embodiment of the invention. As shown,
hair cutting device 2600
includes housing 2602, which comprises surfaces that define cavity 2604
disposed at least partially within
housing 2602. Housing 2602 also includes opening 2606 that communicates with
cavity 2604. Rotary
mechanism 2608 (e.g., similar to the rotary mechanism described with respect
to Figure 18C) is at least
partially disposed within cavity 2604. Rotary mechanism 2608 includes multiple
rotational components
2610 and 2612 (such as the rotational components described with respect to
Figures 7 A-C and 8 A-C,
etc.) that are configured to substantially coaxially rotate (e.g., coaxially
counter-rotate) relative to one
another. Rotational components 2610 and 2612 also include cutting implements
2614 (e.g., razor blades
or other sharp edges) that are configured to cut hair via opening 2606 when
the multiple rotational
components 2610 and 2612 substantially coaxially rotate relative to one
another and cutting implements
2614 (see, e.g., implements 716 and 818 or the like) contact the hair (see,
e.g., Figure 26F). Rotary
mechanism 2608 also includes at least one counter-rotational mechanism, as
described herein (see, e.g.,
the multiple assembled rotational mechanisms schematically depicted in, e.g.,
Figures 18A-C or the like),
operably coupled to the multiple rotational components 2610 and 2612. The
counter-rotational
mechanism is configured to effect substantially simultaneous counter-rotation
of the multiple rotational
components 2610 and 2612 relative to one another when movement of at least a
portion of the counter-
rotational mechanism is effected. That is, rotational component 2610 is
configured to rotate in a direction
that is opposite the direction of rotation of rotational component 2612. In
some embodiments, the
rotational components are configured to coaxially counter-oscillate relative
to one another about an axis
of rotation of the rotary mechanism. In some of these embodiments, cutting
implements include dual-side
cutting edges, e.g., to cutting hair in both directions of the oscillation.

[0140] As also shown, hair cutting device 2600 also includes a drive mechanism
operably coupled to the
counter-rotational mechanism and rotational components. In the embodiment
shown, for example, in
Figures 26A and 26C, the drive mechanism includes motor 2616 (e.g., a stepper
motor, a servo motor,
etc.), which is configured to effect movement of the counter-rotational
mechanism via shaft 2618 such
that the multiple rotational components 2610 and 2612 substantially
simultaneously counter-rotate
relative to one another. As also shown, switch 2617 (e.g., on/off switch, a
variable speed control switch,
and/or the like) is operably connected to motor 2616. Although not shown, hair
cutting device 2608 also

43


CA 02737322 2011-04-14

typically includes a power source (e.g., a power cord that plugs into a wall
socket, a battery (rechargeable
or not), a photovoltaic cell, etc.) operably connected to motor 2616.

[0141] Hair cutting device 2600 also includes removable structure 2620 (e.g.,
a shaving foil structure or
the like) disposed in opening 2606. Removable structure 2620 comprises holes
2622 via which hair is cut
when the multiple rotational components 2610 and 2612 substantially coaxially
counter-rotate relative to
one another and cutting implements 2614 contact the hair. Hair cutting devices
also typically include
support structures that are structured to support at least a portion of the
rotational components, the
counter-rotational mechanism, and/or the drive mechanism within the device
housings. As shown in
Figure 26F, for example, hair cutting device 2600 is dimensioned to be hand-
held (i.e., person 2621 is
holding hair cutting device 2600 in his hand). As shown, e.g., Figure 26G
housing 2602 of hair cutting
device 2600 comprises at least one substantially circular cross-section.

[0142] Figures 27 A-D schematically illustrate an exemplary tooth brushing
device or components
thereof according to one embodiment of the invention. As shown, tooth brushing
device 2700 includes
rotary mechanism 2702, which includes a plurality of rotary units 600, as
described above. Tooth
brushing device 2700 also includes toothbrush head component 2704 and handle
component 2706.
Toothbrush head component 2704 includes rotary mechanism housing 2708, which
partially exposes a
portion of the bristles of rotary mechanism 2702 through an opening in rotary
mechanism housing 2708
during operation. Toothbrush head gear components 2710 and drive shaft 2712
also extend from a
portion of rotary mechanism housing 2708. Drive shaft 2712 is received through
drive mechanism
receiving areas of rotational components 602 of rotary units 600 of rotary
mechanism 2702. Toothbrush
head gear components 2710 operably engage gear components 604 and 624 of a
rotary unit 600 to effect
counter rotation of neighboring rotational components 602 and implements 622
of rotary mechanism
2702. Rotary mechanism cap 2714 attaches to drive shaft 2712 to retain rotary
mechanism positioned
relative to toothbrush head gear components 2710. Handle component 2706 houses
a motor (not within
view) the operably connects to toothbrush head gear components 2710 and drive
shaft 2712. A power
source, such as a rechargeable battery or the like is also housed in handle
component 2706 is some
embodiments. In certain embodiments, the motor is optionally connected to
other types of power sources,
such as photovoltaic cells attached to handle component 2706, external power
sources, or the like. As
also shown, handle component 2706 also include switch 2716, which is used,
e.g., to turn tooth brushing
device 2700 on and off, regulate speeds or modes of rotary unit rotation, or
the like.

[0143] Figures 28 A and B schematically show an exemplary rotary mechanism or
toothbrush head
component that is optionally used, e.g., with handle component 2706 of tooth
brushing device 2700. As
44


CA 02737322 2011-04-14

shown, rotary mechanism 2800 includes a plurality of rotary units 600 in which
implements 2802 (raised
elastomeric regions, e.g., for tooth polishing) have been substituted for
implements 622 on several
individual rotary units. Figure 28B schematically shows toothbrush head
component 2804, which
includes rotary mechanism 2800.

[0144] Figure 29 schematically illustrates an exemplary cleaning device from a
side view according to
one embodiment of the invention. As shown, cleaning device 2900 includes a
rotary mechanism that
includes rotary units similar to rotary units 800, which are described further
herein. Exemplary uses of
cleaning device 3900 include cleaning outdoor cooking grills, dishes, and
toilets, among many possible
applications.

[0145] To further illustrate representative embodiments, rotary units and
rotary mechanisms are
optionally used or adapted for use in various types of engines and other
propulsion devices or systems.
For example, Figures 30 A-F schematically illustrate a propulsion device or
components thereof
according to one embodiment of the invention. As shown, propulsion device 3000
includes two rotary
mechanisms 3002 and propeller component 3004. Rotary mechanisms 3002 include a
plurality of rotary
units 300, as described herein. Rotary units 300 are operably coupled to one
another via shaft 3006,
which includes gear component 3008. Shaft 3006 operably connects to motor 3010
and rotary
mechanism cap 3012. Gear component 3008 operably engages third gear components
312 of gear
structure 310 of a rotary unit 300 such that when motor 3010 effects the
rotation of gear component 3008,
gear component 3008 effects the counter rotation of neighboring pairs of
rotary units 300. Gear
components 324 of rotary units 300 operably engage corresponding gear
components of propeller units
3014 (e.g., rotational units or the like) to effect the counter rotation of
neighboring pairs of propeller units
3014 of propeller component 3004, and thereby propulsion. Rotary mechanism cap
3012 aligns and
maintains the position of rotary units 300 relative to one another. Although
two rotary mechanisms 3002
are depicted in this propulsion device embodiment, fewer or more that two
rotary mechanisms are
optionally used.

[0146] Figures 32 A-D schematically illustrate a propulsion device or
components thereof according to
one embodiment of the invention. As shown, propulsion device 3200 includes two
rotary mechanisms
3202 and propeller component 3004. Rotary mechanisms 3202 include a plurality
of rotational
components 3204. Rotational components 3204 are fixedly coupled to one another
via shaft 3206. Shaft
3206 operably connects to motor 3010 and rotary mechanism cap 3012. As shown,
one shaft 3206 is
fixedly coupled to a first set of four non-neighboring gear components 3204,
while the other shaft 3206 is
fixedly coupled to a second set of four non-neighboring gear components 3204
that is different from the


CA 02737322 2011-04-14

first set of four non-neighboring of gear components 3204. The two shafts 3206
are configured to rotate
in opposite directions. See, e.g., the directional arrows associated with the
two rotary mechanisms 3202
in Figure 32B. As shown, in an assembled propulsion device 3200, gear
components 3204 of the first and
second sets of four non-neighboring of gear components 3204 mesh with
corresponding gear components
of different propeller units 3014 (e.g., rotational units or the like) of
propeller component 3004 such that
when the first and second sets of four non-neighboring of gear components 3204
rotate in opposite
directions to one another, neighboring pairs of propeller units 3014 of
propeller component 3004 counter-
rotate relative to one another, and thereby effect propulsion.

[0147] Propeller component 3004 of propulsion device 3000 and 3200 includes a
plurality of propeller
units 3014 (e.g., rotational units or the like), which in this embodiment each
include a plurality of
propellers 3016. Many different types of propellers are optionally used or
adapted for use in the engines
or propulsion devices of the invention. In some embodiments, for example,
individual propeller
components 3004 may have propellers 3016 that differ in size from the
propellers of other propeller
components in a given propulsion device 3000 or propulsion device 3200.
Propeller units 3014 are
operably coupled together in propeller component 3004 via propeller component
shaft 3018 and propeller
component cap 3020. As also shown, certain propeller units 3014 include
rotational alignment
components 3022, which are positioned and rotate in corresponding rotational
positioning components
3107 of propulsion component housing 3100 (e.g., a positioning component or
the like), e.g., to prevent
propeller units 3014 from contacting propulsion component housing 3100 during
operation. See, e.g.,
Figures 31 D and E.

[0148] The engine and propulsion devices have many different uses. For

that optionally are
adapted for use with the cleaning devices of the invention are also described
in, e.g., U.S. Provisional
Patent Application No. 61/317,746, entitled "CLEANING IMPLEMENTS, CLEANING
MATERIAL
COMPONENTS, AND RELATED METHODS", filed on March 26, 2010, which is
incorporated by
reference in its entirety.

[0158] To further illustrate, Figures 41 A-Q schematically show cleaning
devices, cleaning material
components, or components thereof from various views according to exemplary
embodiments of the
invention. As shown, cleaning device 4100 includes head component 4102 which
includes cleaning
material support component 4104 and cleaning surface component 4106. Cleaning
material support
component 4104 includes cleaning material support component surfaces 4108 that
at least partially define
cleaning material receiving areas 4110 (shown as cleaning implement cartridge
receiving areas). As also
shown, cleaning material support components 4104 include openings 4112 that
are structured such that
cleaning material receiving areas 4110 communicate with cleaning surface
component 4106. As shown,
cleaning material receiving areas 4110 are configured to receive cleaning
material component 4114
(shown as a cleaning implement cartridge that includes a cleaning material
roll) such that at least a
portion of cleaning material component 4114 is movable to and/or from cleaning
material receiving area
4110 to extend over at least a portion of cleaning surface component 4106. In
addition, cleaning device
4100 also includes retaining component 4120 (shown as a door structure) that
operably engages cleaning
material support component 4104 via slide component 4122 in this exemplary
embodiment. As shown,
head component 4102 also includes rotary mechanism 2116.

[0159] Cleaning material component 4114 includes cleaning material support
structures 4130 and
cleaning material 4126 (shown as a rolled sheet of cleaning material).
Cleaning material support
structures 4130 (shown as substantially cylindrically-shaped housings) form
cavities that are each
structured to house and support cleaning material 4126 such that cleaning
material 4126 is movable to

49


CA 02737322 2011-04-14

and/or from cleaning material support structures 4130 via orifices 4132.
Orifices 4132 are configured to
communicate with openings 4112. Cleaning material support structures and
corresponding cleaning
material receiving areas are optionally formed to include various cross-
sectional shapes, including, e.g.,
circles, ovals, squares, rectangles, regular n-sided polygons, irregular n-
sided polygons, etc. As shown,
cleaning material support structure 4130 is configured to be received in
cleaning material receiving area
4110 of cleaning device 4100 and cleaning material 4126 is configured to
extend over cleaning surface
component 4106 of cleaning device 4100 via orifices 4132 and openings 4112.

[01601 In some embodiments, cleaning material support structures and/or
cleaning materials of cleaning
material components include one or more alignment components that are
configured to align cleaning
materials relative to cleaning material support structures. To illustrate,
cleaning material support
structures 4130 of cleaning material component 4114 includes rod 4134 that
extends within cleaning
material support structure 4130. As shown, the alignment component (rod 4134)
of cleaning material
support structure 4130 inserts into a corresponding central receiving area of
the cleaning material roll
(cleaning material 4126) to align cleaning material 4126 relative to cleaning
material support structures
4130.

[01611 In certain embodiments, cleaning devices and/or cleaning material
components operably connect,
or are operably connectable, to conveyance mechanisms or components thereof to
effect conveyance of
cleaning materials, e.g., selected incremental distances. In cleaning device
4100, for example, rod 4134
extends through cleaning material support structure 4130 and operably connects
to conveyance
mechanism component 4140 that is configured to operably engage gear components
4139. In particular,
projections 4137 of conveyance mechanism component 4140 are configured to be
received by projection
receiving areas 4135 of gear components 4139. Gear components 4139 are
configured to operably
engage gear component 4141 of head component 4102 when cleaning material
component 4114 is
disposed in cleaning material receiving areas 4110. As shown, gear component
4141 is operably
connected to motor 4143 (e.g., a stepper motor, a servo motor, etc.) via shaft
4145. Power source 4147
(shown as a battery, e.g., a disposable battery, a rechargeable battery, etc.)
operably connects to motor
4143 to provide power to motor 4143. Essentially any power source is
optionally adapted for use with the
cleaning devices of the invention. In some embodiments, for example, motors
are operably connected to
power cords that plug into power outlets. In other exemplary embodiments,
photovoltaic cells are
mounted cleaning devices to provide power to motors. Motor 4143 effects
rotation of cleaning material
roll (cleaning material 4126) (via gear components 4139 and 4141) selected
distances such that cleaning
material 4126 is positioned at selected positions relative to cleaning surface
component 4106. Although


CA 02737322 2011-04-14

not within view, motor 2118 is also operably connected to power source 4147.
Motor 2118 effects
rotation of rotary mechanism 2116.

[01621 Typically, cleaning material support components of cleaning devices
and/or cleaning material
components include one or more alignment features that are structured to align
those components relative
to one another when the cleaning material components are disposed in the
cleaning material receiving
areas of the cleaning devices. In one exemplary embodiment, for example,
cleaning material support
structure 4130 and cleaning material support component 4104 include alignment
features 4142 and 4144,
respectively (schematically shown as corresponding tongue and groove-type
components), that are
structured to align cleaning material support structure 4130 relative to
cleaning material support
component 4104 cleaning device 4100.

[01631 The cleaning devices of the invention typically include one or more
handle components. As
shown in Figures 41N-P, for example, cleaning device 4100 includes handle 4146
operably connected to
head component 4102. Handle 4146 is pivotally connected to head component 4102
via pivot mechanism
4148 (shown as a ball and socket mechanism). As also shown, handle 4146
includes switch 4150 which
is operably connected to motor 4143. Switch 4150 is used to effect movement of
cleaning material 4126
via the conveyance mechanism described above.

[01641 In some embodiments, cleaning devices include fluid handling mechanisms
that can be used, for
example, to distribute fluid (e.g., a cleaning fluid, etc.) to a surface to
cleaned, to a cleaning material of a
cleaning device (e.g., to moisten the cleaning material prior to or during use
of the cleaning device, etc.),
and/or the like. To illustrate one exemplary embodiment, cleaning device 4100
includes a fluid handling
mechanism that comprises a fluid source (container 4154) and fluid outlets
(nozzles 4152) (shown
disposed proximal to a surface of head component 4102). The fluid handling
mechanism is configured to
convey fluid from container 4154 to nozzles 4152, which communicate via fluid
conduit 4156. The fluid
handling mechanism of cleaning device 4100 also includes pumping mechanism
4158 (e.g., a rotary lobe
pump, a rotary gear pump, a screw pump, a gear pump, a peristaltic pump, or
the like) that is configured
to pump the fluid from container 4154 to nozzles 4152. As also shown, the
fluid handling mechanism
also includes vaporization component 4160 (e.g., a steam vaporizer or the
like) that is configured to
vaporize the fluid at least proximal to nozzles 4152. In the embodiment shown,
container 4154 is
removable from cleaning device 4100 such that container 4154 can be, e.g.,
refilled with a cleaning fluid,
replaced with a new container when container 4154 is fabricated as a
consumable component of cleaning
device 4100, etc. In some embodiments, containers are fabricated integral or
otherwise fixedly attached
to cleaning devices. Switch 4150 is also configured to effect operation of
pumping mechanism 4158 and
51
