STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] The present invention relates to toy entertainment devices,
and more particularly to a toy having one or more intelligent
elements configured to mimic the appearance of a person, animal,
vehicle or other character and adapted to perform specified actions
upon encountering one or more environmental elements.
[0005] 2. Description of Related Art
[0006] A variety of different toys are known that comprise
individual objects configured to mimic the appearance of a person,
animal, vehicle or other character for use in combination with
objects configured to simulate an environment in which the
character can perform real or imaginary life activities. For
example, the Fisher Price.RTM. line of Little People.RTM. products
encompasses toy people, animals and vehicles that can be manually
positioned and moved in and amongst various structures such as
house, barn or castle. Battery powered robotic toy objects are also
known that can operate in conjunction with environmental elements,
such as battery operated cars configured to run on a track, battery
operated baby dolls programmed to engage or interact with a toy
baby bottle or pacifier, and robotic pets programmed to make
movements or noises that simulate a real life animal.
[0007] While robotic or battery operated toys are more life-like
than non-powered objects, the robotic toys that exist in the toy
industry to date are limited in their ability to provide a real
life experience, because most of these robotic toys require the use
of a remote control or specific commands from a child to operate.
The toys do not operate "on their own" outside the control of the
child.
[0008] One exemplary embodiment of the present invention is
directed to an intelligent toy hamster. Real hamsters typically
live in habitats comprising tubes, tunnels, and the like. The
habitats are assembled and expanded upon with accessories such as
hamster balls or exercise wheels to enhance the entertainment value
of the pet. The pets that dwell in these habitats move about under
their own will and are very enjoyable to watch. Unfortunately, pet
hamsters require a great amount of maintenance. For instance, pet
hamsters require food and water, and generate waste that needs to
be cleaned-up regularly. It would therefore be advantageous to
provide a toy hamster that supplied the same entertainment as a
real hamster but without the maintenance requirements. Existing toy
pets that utilize a remote control or respond to specific commands
of the child do not provide the complete experience of a real pet
that has a "mind of its own."
BRIEF SUMMARY OF THE INVENTION
[0009] The present invention is directed to an interactive
intelligent toy that provides the appearance and experience of a
person, animal, vehicle, or other character moving in, and/or
interacting with, its environment or habitat on its own. The toy
comprises one or more intelligent elements configured to simulate a
person, animal, vehicle or other character and adapted to perform
certain activities in conjunction with one or more environmental
elements. In one embodiment, the intelligent element is programmed
or adapted to perform certain activities in response to an
environmental element. For example, the intelligent element
(simulating a car) may generate a noise (a honking horn) upon
passing a portion of an environmental element (simulating a house).
Additionally, the intelligent element (simulating a super hero) may
move (expand its arms forward as if to fly through the air) upon
engaging with an environment element (simulating a cape). In
another embodiment, the intelligent element is programmed or
adapted to provide the means necessary for the environmental
element to perform certain activities. For example, the intelligent
element (simulating a person) may provide the power and control
mechanisms needed to move an environmental elemental (simulating a
car). The invention therefore provides a simulated character that
appears to have a mind of its own in operating within a certain
environment. Furthermore, given that the intelligent element is
able to supply the means (drive mechanism, control mechanism and
power source) to enable other elements to perform actions, the cost
of the toy can be minimized while providing a large variety of
different activities and the ability to expand to new environments
and activities.
[0010] In one embodiment, the intelligent element comprises a
motive component. The motive component has a drive mechanism for
moving the element, a control mechanism that directs the motive
component to perform certain activities such as moving, making
noise, changing color or generating light based upon its
interaction with one or more environmental elements, and a power
source to power the drive mechanism and control mechanism. The
environmental elements may comprise one or more pathway components
on which the motive component travels and one or more coupling
components with which the motive component engages to perform
certain activities in conjunction with the coupling components.
[0011] As to operation with the pathway components, codes may be
embedded or otherwise presented at different locations along the
pathway component. The control mechanism comprises sensors that
identify the codes and direct the motive component to perform a
specified activity in response to the code. This activity could be
a certain pre-programmed movement in response to the code or the
generation of a specified sound, color change, or light, or other
activity responsive to the code.
[0012] As to operation with the coupling components, the coupling
component may be shaped to resemble the appearance of a moving
object such as a motorized vehicle, train, plane, helicopter,
skateboard, surfboard, or bicycle. In this embodiment, the coupling
component does not include its own drive mechanism, power source,
or other control mechanism. The motive component and coupling
component are configured to engage in a manner such that the drive
mechanism of the motive component can be utilized to move both the
motive and coupling components combined. The motive component may
instead or in addition be configured to engage the coupling
component and perform a different activity such as making a noise
while the two components are engaged.
[0013] It is noted that the intelligent element need not be a
motive component in order to perform in accordance with the present
invention. For instance, the coupling component may include its own
drive mechanism, but not include a power source or control
mechanism. In this instance, the intelligent element is configured
to engage the coupling component in such a way as to provide power
to the coupling component so that the coupling component can
utilize its own drive mechanism to move the coupling component in
combination with the intelligent element. In addition, the
intelligent element may be configured to engage a coupling
component so as to provide power to other equipment on the coupling
component such as lights or sound generators. In this fashion, the
intelligent element serves as a power source that, when engaged
with the coupling component, provides power to the coupling
component to operate and perform particular activities. The
intelligent element may also provide the control mechanism for a
coupling component. For example, a coupling component may have a
drive mechanism and may also have a separate power source such as
batteries, but may not have any circuitry in order to control the
drive mechanism or power source. The intelligent element may be
configured to engage the coupling component in such a manner that
the control mechanism of the intelligent element can control
operation of the drive mechanism and power source contained within
the coupling component.
[0014] It is noted that more than one intelligent element may be
provided wherein each intelligent element is programmed to perform
different actions in response to the codes contained within a
pathway component or engagement with a coupling component. In this
manner, the different intelligent elements appear to have a
different personality because they respond differently to the same
environmental elements. This creates an even more realistic,
real-life experience for the child wherein different intelligent
elements have different personalities and reactions to the same
environmental stimulus. For example, a first hamster toy, Mr.
Squiggles, may laugh "ha ha ha" whenever it passes over the coding
on a pathway component at the top of a slide, whereas a second
hamster toy, Yum Yums, may yell "yahoo" upon passing over the
coding at the top of the slide. Similarly, Mr. Squiggles may be
programmed to move forward in a straight line when engaging a
skateboard coupling component, while Yum Yums may be programmed to
move in a circle eight configuration when engaging the surfboard.
Furthermore, a given intelligent element does not always perform
the same action in response to the same stimulus. Unlike
track-based toys known in the prior art, which provide only for
predetermined, entirely predictable movement, or radio-controlled
or tethered toys which rely on user input to determine movement and
actions, the intelligent elements of the present invention provide
the appearance of intelligent, thinking animals with self-decision
capability and free-will that perform varied, sometimes seemingly
random, responses to the environment it encounters. As explained in
more detail below, the same intelligent element, encountering the
same code in a pathway will not always respond in the same,
predictable manner. Thus, the appearance and movement of the
intelligent elements is realistic and generally unpredictable.
[0015] In one exemplary embodiment, an interactive intelligent toy
comprises a motive component enclosed by a cover resembling a
hamster with fur coat, eyes, ears, mouth, nose, and whiskers (a
"motive hamster"), a pathway component on which the motive hamster
can travel, and at least one coupling component configured to
releasably engage with the motive hamster. The motive hamster
includes a drive mechanism to enable movement, a control mechanism
operable to control the drive mechanism, monitor and detect user
and event inputs, detect and decode embedded codes from a pathway
component and perform predetermined actions or generate
predetermined sounds in response to the codes, and a power source
to supply power to the drive mechanism upon the command of the
control mechanism and supply power to the control mechanism for its
operation. The motive hamster moves along and through the pathway
component having one or more embedded codes detectable by the
control mechanism. The embedded codes provide information to the
control mechanism to direct desired movement of the motive hamster
or to direct other desired action such as generating a
pre-determined sound.
[0016] The coupling component is configured to mimic the appearance
of a car, skateboard, surfboard, or other mobile object. The
component does not itself have a drive mechanism, power source, or
control mechanism. Instead, the motive hamster is configured to
engage with the coupling component in such a way as to permit the
drive mechanism, power source, and control mechanism of the motive
hamster to drive movement of both the hamster and coupling
component.
[0017] In use, as the motive hamster moves through the various
sections of pathway, encountering "bump codes" embedded in the
pathway while the control mechanism decodes the codes and directs
the motive component to perform specific actions, move in specific
ways, and generate specific sounds in response to the detected
code. Thus, the appearance of the hamster moving through the
pathway is that of a real pet hamster exploring and interacting
with its environment and habitat. The hamster also can, from
time-to-time, encounter and engage with a coupling component such
as an object configured to mimic the appearance of a car or a
surfboard and, upon coupling with the component, continue moving in
combination with the component so as to appear to be driving the
car or riding the surfboard.
[0018] In additional aspects of the invention, the motive component
includes user operable switches to interact with the hamster, and
operation in a free run or explore mode independent of the pathway
component. Various alternative embodiments are described herein,
and other variations and configurations are anticipated by the
present invention. For example, while the invention is described
herein primarily with respect to a configuration resembling a pet
hamster, other configurations may be used, such as other pets
(e.g., dogs, cats, mice, etc.), people or characters (e.g., father,
mother, child, fireman, police man, fairy, witch), or vehicles
(e.g., fire trucks, police cars, etc.) or any other desired
configuration.
[0019] Another embodiment of the present invention is directed to a
motive component configured to engage with an auxiliary component,
with the auxiliary component detectable by control circuitry on the
motive component such that action and/or sounds of the motive
component are directed by the presence of the auxiliary
component.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0038] Interactive intelligent toys in accordance with exemplary
embodiments of the present invention is depicted are FIGS. 1-17.
While the invention will be described in detail herein below with
reference to these exemplary embodiments and alternative
embodiments, it should be understood that the invention is not
limited to the specific configurations shown and described in these
embodiments. Rather, one skilled in the art will appreciate that a
variety of configurations may be implemented in accordance with the
present invention.
[0039] Looking first to FIGS. 1-3 and 8-10, an interactive
intelligent toy in accordance with an exemplary embodiment of the
present invention comprises: (1) an intelligent motive component 10
(FIG. 1) having a drive mechanism, control circuitry operable to
control the drive mechanism, monitor and detect user and event
inputs, and detect and decode embedded codes from a pathway and
perform predetermined actions or generate predetermined sounds in
response, and a power source; (2) a pathway component 12 (FIG. 3)
having one or more embedded codes detectable by the motive
component, the embedded codes providing information to the motive
component to direct desired action of the motive component; and (3)
a coupling component 82 (FIGS. 8-10) configured to mimic the
appearance of a car and releasably engage with motive component 10
in a manner to permit the drive mechanism of motive component 10 to
move coupling component 82 in combination with motive component
10.
[0040] As depicted in FIGS. 1-3, motive component 10 and pathway
component 12 preferably resemble a pet hamster and its habitat,
respectively, with the interactive intelligent toy of the present
invention allowing one or more pathway components and one or more
motive components to be configured, assembled and used in various
combinations to simulate the environment, habitat and actions of an
actual pet hamster. The control circuitry communicates with various
switches and sensors on the motive component to detect user or
environment/habitat inputs and provides apparent intelligent
control to the toy, for example, by generating sounds or actions in
response to various detected embedded codes in the pathway and by
altering the movement of the motive component in response to a
detected obstacle. The overall effect of the combined intelligent
motive component and pathway component is that of an intelligent
animal (e.g., a hamster) exploring and interacting with its habitat
and environment.
[0041] As depicted in FIGS. 8-10, coupling component 82 resembles a
car wherein coupling component 82 is configured to permit motive
component 10 to drive onto the coupling component and releasably
engage the coupling component in a manner to permit the drive
mechanism of motive component 10 to move both the coupling
component 82 and motive component 10 while engaged.
[0042] Looking to FIGS. 1 and 2, motive component 10 comprises a
chassis 14, which houses control circuitry and batteries (as
described in more detail below) and supports a drive mechanism 16,
with a decorative cover 18 positioned over and covering the top
portion of the chassis.
Cover
[0043] As best seen in FIG. 1, cover 18 is configured to resemble a
pet hamster having a fur coat with eyes, ears, nose, and whiskers.
Control switches (described in more detail below) in communication
with the control circuitry are positioned on or embedded under
cover 18 such that the switches can be activated through the cover
by pressure applied to the corresponding area of the cover.
Preferably, the control switches are activated by a user pressing
the corresponding area of the cover or by the action of the motive
component bumping into an object or obstacle during movement in its
habitat or environment. Operation or activation of each control
switch provides a signal to the control circuitry to perform a
specific action.
[0044] For example, cover 16 preferably includes a bump sensor
switch located under the nose 20 of the hamster operable to detect
the front of the motive component bumping into an obstacle when the
motive component is in motion. That same switch also serves as a
"try me" switch activated by a user to initiate a demonstration
mode when the toy is packaged for display or sale. A control switch
positioned on the back 22 of the hamster is preferably operable to
wake the toy from a "sleep mode" and to turn on and off an
"explore" mode, with a control switch positioned at the head 24 of
the hamster preferably operable to wake the toy from sleep mode,
turn off the explore mode, and to generate predetermined sounds
simulating cooing and/or speech. As will be described in more
detail below, the control circuitry of the motive component is
operable to detect activation of the various control switches and
to command the motive component to perform various actions in
response to activation of the control switches, or to various
combinations of the control switches.
Chassis
[0045] Looking to FIG. 2, chassis 14 includes a drive mechanism 16
positioned near the rear of the chassis operable to transport
motive component 10 in forward or reverse directions, with a glide
post 22 positioned at the center front portion of the chassis that
functions: (1) to guide the motive component to follow a groove or
raceway in a pathway or surface such as a channel or path formed to
guide the motive component between a series of raised bumps formed
in the pathway defining a bump code (as will be described in more
detail below); (2) to elevate the front portion of the motive
component from a surface so that the cover 18 does not drag and
impede the travel of the motive component; and (3) to provide a
contact surface 23 allowing the motive component to glide across a
smooth surface. Glide post 22 also allows the motive component to
make sharp turns or pivot, particularly when turning in reverse as
described below.
[0046] Drive mechanism 16 preferably comprises a direct current
motor in mechanical communication with wheels 26a, 26b so that
rotation of the motor rotates the wheels to transport the motive
component forward or backward. The motor is in electrical
communication with the control circuitry which provides power to
the motor, with the capability to switch the polarity of the
command signal to drive the motor in either a forward or reverse
direction.
[0047] A kickstand 28 coupled to the drive mechanism is positioned
near wheel 26b, and is operable to extend when the drive mechanism
rotates in a first direction and to retract when the drive
mechanism rotates in a second direction. When the kickstand
extends, it contacts the surface to raise the side of chassis 14
near wheel 26b so that wheel 26b is lifted slightly or entirely off
of the surface. Thus, activation of the kickstand effectively
disables the associated wheel so that only one wheel is engaged
with the surface, causing the motive component to turn in a sharp
arc. Preferably, the kickstand extends when the drive mechanism
rotates in reverse, and retracts when the drive mechanism rotates
forward so that the motive component turns in a sharp arc in
reverse. Most preferably, wheels 26a and 26b are approximately the
same size so that forward rotation of the motor drives each wheel
equally such that the motive component moves in a substantially
straight path forward.
[0048] Other arrangements of the drive mechanism, wheels, and
kickstand are contemplated by the present invention. For example,
wheel 26a could be a slightly larger diameter than wheel 26b so
that forward or reverse motion of the motive component would be in
gradual arc rather than in a straight line. As depicted in FIG. 7,
in conjunction with the kickstand as just described, such a
configuration would result in motive component 10 moving in a
gradually arced path 30 when moving in a forward direction, and
moving in a sharply arced path 32 when moving in reverse. The
distance moved in each of the forward and reverse directions is
controlled by predetermined timing intervals in the control
circuitry, by random timing intervals in the control circuitry, by
detection of obstacles thorough a control switch (e.g., the nose
bump switch) as previously described, or combinations thereof.
[0049] As seen in FIG. 7, the overall effect of the combination of
relatively short forward and reverse movement of the motive
component, with the direction changes, is that of a hamster
exploring its habitat. Other variations in the combination of wheel
size, kickstand operation, and timing of forward and reverse
movement will be apparent to those skilled in the art and are
within the scope of the present invention. For example, a slip
gear, kickout gear, or sloppy axle could be used in the drive
mechanism instead of the kickstand to provide sharp turning of the
motive component in a particular direction. Or, separate drive
motors for each wheel or adjustable gearing to vary the drive ratio
of each wheel could be implemented.
[0050] Looking again to FIG. 2, bump code sensors 34a, 34b,
positioned on opposite sides of glide pin 22, are operable to
detect a series of bumps in the pathway defining a "bump code," the
bump code being decoded by the control circuitry and defining a
desired action of the motive component as will be described in more
detail below. Preferably bump code sensors 34a, 34b are mechanical
spring-loaded pushbutton type switches operable to actuate as they
are depressed by a series of raised bumps passing under and
contacting the sensors as the chassis is transported across the
series of bumps. Bump code sensors 34a, 34b are in electrical
communication with the control circuitry described below, which is
operable to decode the sequence/series of bumps detected into a
desired action of the motive component.
[0051] Preferably, bump code sensors 34a, 34b are inexpensive
mechanical type switches that interface to the control circuitry
with no additional power requirements. However, other types of
sensors may be used (with corresponding changes to the type of
codes implemented in the pathway component) in accordance with the
present invention. For example, sensors 34a, 34b could be infrared
(IR) readers operable to detect a corresponding bar code label on
the pathway component. Or, the sensors could be a radio frequency
identification transponder operable to activate and capture data
from an RFID tag embedded or otherwise placed in the pathway
component.
Control Circuitry
[0052] Turning to FIG. 5, a block diagram of an exemplary
embodiment of control circuitry of the interactive intelligent toy
is depicted. The control circuitry includes a microcontroller 40
operable to execute programmed instructions, to monitor inputs and
control outputs according to those programmed instructions, and to
generate sound signals. Micro controller 40 may be any
microcontroller known in the art having the capabilities to perform
the functions described herein. Preferably, microcontroller 40
includes onboard Read Only Memory (ROM) 42, Static Random Access
Memory (SRAM) 44, and a Programmable Sound Generator (PSG) having a
Pulse Width Modulated (PWM) Digital to Analog Converter (DAC)
46.
[0053] Read Only Memory (ROM) 42 stores the program code and
instruction that are executed by the microcontroller which defines
the operation of the motive component. ROM 42 also stores the audio
data files used by the microcontroller to generate sounds.
Preferably the audio data files are in ".wav" format, although
other audio file formats known in the art may equally be used with
appropriate decoding software running on the microcontroller. ROM
42 may also store any other programming, audio, data, or
configuration parameters as required. As is known in the art, ROM
42 provides essentially permanent storage of the program code,
audio data files, and other data or instructions stored thereon,
retaining that data even when no power is applied to the ROM.
Static Random Access Memory (SRAM) 44 provides temporary storage
for data and variables generated by and used by the microcontroller
as the program executes. As is known in the art, SRAM 44 stores
data only when power is applied.
[0054] Programmable Sound Generator (PSG) and Pulse Width Modulated
(PWM) Digital to Analog Converter (DAC) 46 provides the capability
to convert audio data to an electrical signal, as is known in the
art. The electrical signal is transmitted to speaker 48 which
converts the electrical signal to an acoustical wave, preferably in
the form of a human-perceptible sound. Speaker 48 is preferably a
miniature Mylar speaker positioned on the chassis 14 of the motive
component as described above. Of course other types of speaker
devices, such as piezoelectric transducers, may also be used.
[0055] Microcontroller 40 controls motor 50 through lines 52a, 52bb
that provide a voltage and current output to the motor. Motor 50 is
the direct current motor portion of the drive mechanism 16 portion
of the motive component as described above. Microcontroller 40 is
operable to switch the polarity of the signals provided through
lines 52a, 52b to drive the motor in either the forward or reverse
directions to control the movement of the motive component.
[0056] Switches 20', 22', and 24' (corresponding to the nose, back,
and head portions of the cover 18 as described above) provide
inputs to microcontroller 40 indicating operator input or input due
to contact of the motive component with an obstacle. For example,
activation of switch 20' corresponds to the nose of the motive
component, indicating that the motive component has bumped into an
obstacle. Activation of switch 22' or 24' corresponds to the back
and head portions, respectively of the cover 18, indicating user
interaction with those areas. For example, activation of switch 24'
(corresponding to the head portion of the hamster) indicates that a
user is touching or stroking the hamster's head. In response,
microcontroller 40 activates a cooing or voice audio file to
produce that sound through speaker 48. From the user's perspective,
stroking the hamster's head causes it to coo. Similarly, the other
input switches cause the microcontroller to perform specific
actions. Activation of the nose switch 20' indicates that the
hamster has bumped into an obstacle. In response, the
microcontroller reverses the direction of motor 50 to change the
direction the hamster is traveling. It will be apparent to those
skilled in the art that various combinations of inputs thus could
instigate various actions by the microcontroller to control the
movement and/or sound of the motive component/hamster.
[0057] Bump code sensors (corresponding to bump code sensors 34a,
34b described above) provide inputs to the microcontroller 40 and
correspond to the bump code sensors located on either side of the
glide pin 22 on the chassis 14 as described above. Microcontroller
40 is operable to detect the inputs from the bump code sensors and
to decode the various bit patterns detected according the bump code
protocol described below. Upon detecting and decoding a bump code,
the microcontroller performs specific actions according to that
bump code. Power to the microcontroller is preferably provided by
three AAA size batteries positioned on the top side of chassis 14
described above. Of course other power sources, such as
rechargeable cells or batteries and storage capacitors may also be
used.
[0058] Microcontroller 40 is preferably a single integrated circuit
(IC) having all of the functionality of the ROM 42, SRAM 44, and
PSG/PWM DAC 46 on-board and built-in. However, other arrangements,
configurations, and variations are within the scope of the present
invention. For example, the ROM, SRAM, and DAC could each be
discrete components controlled by a discrete microprocessor IC. Or
the PSG/PWM DAC and speaker functionality could be built or
combined into a separate device.
Pathway Component
[0059] Looking to FIGS. 3 and 4, pathway component 12 comprises one
or more sections of pathway configured as a tube or tunnel 60, a
circular slide 62, or room 64. As described above, pathway
components may likewise be configured or designed as any desired
configuration corresponding to hamster habitat pieces and devices
as used with an actual pet hamster, such as exercise wheels, or may
be configured and designed as other whimsical or toy devices, such
as cars or trucks. Thus, it should be understood that the pathway
components described and depicted in the exemplary embodiments
described herein are exemplary in nature, and not limiting of the
scope of the present invention. Unlike tracks or tethers used with
toy motorized vehicles as known in the prior art, the pathway
component does not rigidly guide the motive component in a
predetermined course, rather it generally directs the motive
component, allowing the motive component to apparently
intelligently explore its environment in a manner similar to that
of a living animal.
[0060] Looking to FIG. 3, a close-up partial view of a portion of
an exemplary pathway component shows that the pathway component
includes a floor surface 70 with walls 72a, 72b extending upwardly
from opposite sides of the floor to forma semi-enclosed pathway.
Viewed in conjunction with the motive component described
previously, it can be seen that the motive component can move along
the floor surface 70 of the pathway, guided and contained by the
walls 72a, 72b on either side. Thus, looking to FIG. 4, it can be
seen that the motive component can move along various
configurations of the pathway component, such as a circular slide
62 or a tunnel or tube 64.
[0061] Looking back to FIG. 3, the pathway component includes one
or more tabs 74 and receptacles 76 configured to interlock with
corresponding tabs and receptacles similarly positioned on
additional pathway components so that multiple pathway components
can be connected together to form a complete habitat. As seen in
FIG. 4, various pathway components (circular slide 62, tunnel 60,
and room 64) are connected together in an exemplary habitat.
[0062] The pathway component includes a bump code 78, comprising a
series of raised bumps formed in the floor surface 70, with guide
recesses 80 formed in the floor surface at opposite ends of the
bump code to direct the glide pin 22 of the motive component
between the two rows of raised bumps. Thus, the bump sensors 34a,
34b of the motive component are each aligned with the corresponding
rows of bumps to detect those bumps as the motive component is
transported past the bump code, activating bump sensors 34a, 34b as
previously described.
[0063] Thus, the pathway components not only generally direct the
motive component, but also align the motive component to detect the
bump codes formed in the pathway. While the bump codes are
preferably raised bumps formed in the pathway, it should be
understood that other detectable codes could be used within the
scope of the present invention. For example, the codes in the
pathway could be bar codes detectable by a corresponding IR sensor
on the motive component, or the codes could be RFID tags detectable
by a corresponding RFD transponder on the motive component.
[0064] Looking to FIG. 4, it should be apparent that pathway
component room 64 does not have a floor having bump codes, but
instead acts as a connector for multiple tubes, tunnels, or other
pathway components which preferably themselves include a bump code
to direct the motive component as it enters and/or exits the
room.
Bump Code Protocol
[0065] Turning to FIG. 6, an exemplary arrangement of the bump code
pattern and protocol is depicted. The bump code is arranged in a 2
by 6 bit pattern, i.e., two rows, each having six bits. In the
exemplary pattern shown, one row serves as a clock bit row for the
first bump code sensor (e.g., bump sensor 34a, indicating when that
sensor has contacted the clock bit bump) so that the control
circuitry can then read the data from the second sensor (e.g., bump
sensor 34b) by microcontroller 40 decoding the input data as
described above. The spacing of the bits of the bump code pattern
is preferably such that the overall length x of the pattern is at
least 42 millimeters, with the total distance between the trailing
edges of successive bits y+z at least 6 millimeters, and a minimum
of 1 millimeter z between the trailing edge and leading edge of
successive bits.
[0066] As depicted in FIG. 6, the 2 by 6 bit pattern with clock
bits provides four data bits (bit 0, bit 1, bit 2, and bit 3),
which correspond to sixteen unique codes that can be encoded by the
bump code pattern. Those sixteen codes are detected and decoded by
the control circuitry to perform various actions and generate
various sounds. For example, looking to FIG. 4, a motive
component/hamster traveling up tube 60 to circular slide 62
encounters a bump code 66 that preferably indicates that the
pathway component is a circular slide. The bump code is detected
and decoded by the control circuitry which then performs the
actions associated with the circular slide bump code, e.g.,
generate a "wheee" sound that plays through speaker 42 as the
hamster travels down the slide.
[0067] It should be understood that the bump code as described may
be bidirectional, such that a series of bumps that provide a
specific bit pattern in one direction may, and likely will, provide
a different bit pattern when read in a different direction. Thus,
for example, a single bump code located on a portion of pathway
adjacent a room section may provide one code when the motive
component passes over the bump code upon entering the room (i.e.,
an entrance code) and may provide another code when the motive
component passes over that same bump code upon exiting the room
(i.e., an exit code). It should also be understood that the control
circuitry of the motive component may ignore specific codes or
undefined codes, or that the exemplary bit pattern as just
described may be expanded to provide more bits and thus a
correspondingly greater number of available codes.
[0068] It should also be apparent that various bump codes to
indicate various pathway components can be implemented, for example
a code indicating an exercise wheel component would instigate an
exercise wheel sound, with the motive component moving on that
wheel for a predetermined time, or entering a game room pathway
component would instigate sounds corresponding to playing games,
and so forth. It should also be understood that the actions
performed by the motive component in response to a specific code
need not be the same each time that particular code is encountered.
For example, the control circuitry may have a list of numerous
"game room" responses so that each time the motive component enters
a game room a different sound and/or movement response is selected
from the list (either sequentially or randomly) and that response
is commanded by the control circuitry. Thus, the actions of the
motive component appear more intelligent and random than if only a
single response were provided.
[0069] Furthermore, the control circuitry is preferably programmed
to ignore unrecognized codes (i.e., take no action upon detecting
an unrecognized code) so that any errors or interruptions in
detecting a code will be ignored. For example, slippage of the
wheels of the motive component as the bump sensors are traversing
an embedded code could disrupt the timing of the bit pattern of the
embedded code--resulting in an erroneous bit pattern and detected
code. Such unrecognized codes are ignored by the control circuitry
and no action is taken, unlike prior art track-based systems in
which events are predetermined and predictable. In addition, the
control circuitry is programmed to have an acceptance rate for
detected codes such that even properly detected codes are not
always acted upon. Preferably, the acceptance rate is between forty
and one-hundred percent, most preferably approximately sixty
percent. A less than one-hundred percent acceptance rate allows the
hamster to act seemingly independently and somewhat unpredictably
(like a real hamster), so that the hamster does not always perform
the exact same action in response to a particular detected code. In
conjunction with the coupling components (described in more detail
below), the acceptance rate and ignoring of unrecognized codes add
to the realism of the claimed invention, with the hamster often
performing actions in response to detected codes, but sometimes
"choosing" not to do so. For example, a hamster entering a garage
coupling component will often (in response to a detected code upon
entering the garage) engage with a car coupling component in the
garage and "drive" the car (a typical response for the detected
code). However, with a less than one-hundred percent acceptance
rate, the control circuitry will only sometimes invoke the typical
response (i.e., only sixty percent of the time). Thus, the action
of the hamster in not responding identically to every encounter
with a particular code results in a more intelligent appearance of
its movement--sometimes it does not perform the typical or expected
way, it "chooses" to ignore the code and perform
different-than-expected actions. The acceptance rate and ignoring
of unrecognized codes thus invoke a randomness and more realistic
intelligence appearance to the actions of the motive component.
[0070] Looking once more to FIG. 4, when motive component is moving
within a room component 44, there is no floor or any embedded
codes. Thus, the motive component may move in a random pattern
within the room, forward and backward, detecting bumping into the
walls of the room via the nose bump sensor (and backing up) until
it can exit the room through one of the tunnels, tubes, or other
pathways connected to the room. Preferably, a pathway component
portion on the entrance to the room provides an indication as to
the type of room being entered (e.g., a game room) so that the
control circuitry can play the appropriate sounds when the motive
component enters that room. Also, a pathway component exiting the
room preferably includes a bump code that signals the control
circuitry to generate a new sound and/or perform different actions
of the motive component as it exists.
[0071] Similar to the action of the motive component in a room as
just described, the motive component can operate in a "free run"
mode, apart from any pathway component. In that case, the control
circuitry commands the motive component to travel in a generally
straight line for predetermined time periods, then reversing. Or,
the motive component could be commanded to move in an "explore"
pattern similar to that depicted in FIG. 7, with the hamster moving
in a short series of forward and backward motions. Preferably, the
control circuitry commands that sounds be played thorough speaker
42 during free run mode.
Coupling Component
[0072] Looking to FIGS. 8-10, coupling component 82 is generally
configured to mimic the appearance of a car. Coupling component 82
has a generally flat base or chassis 84 with front and side walls
86 extending upwardly from the chassis to form a frame 88. A shell
90 resembling the top, front and sides of a car is fitted over and
secured to frame 88. An opening 92 is formed along the back of the
coupling component having a width at least as great as the width of
motive component 10 such that motive component 10 can move through
opening 92 to rest on the upper surface of chassis 84. A downwardly
extending ramp 94 is presented along the rear of chassis 84 to
enable motive component 10 to ride up onto the upper surface of
chassis 84. A slot 96 centrally located in the front of chassis 84
is configured to receive the glide pin 22 of motive component 10
when the motive component moves onto the upper surface of chassis
84. Once the guide pin 22 is positioned in slot 96, the motive
component 10 and coupling component 82 are releasably fixed
together. A cut-out 98 in the rear of chassis 84 and on either side
of ramp 94 is configured to enable the wheels 26a and 26b of motive
component 10 to extend below the chassis such that wheels 26a and
26b are able to move both the coupling component 82 and motive
component 10 in tandem. It is noted that codes similar to those
described earlier may also be embedded in the coupling component to
cause the motive component to take a particular action, such as
moving in reverse or in a circle eight pattern or making a noise
upon engaging with the coupling component.
[0073] Coupling component 82 may further include push button areas
that allow activation of the control switches (e.g., switches) 20,
22, 24 on motive component by either pressing on those switches or
by allowing access to those switches. For example, coupling
component 82 may include a push button or resilient area
corresponding to the location of control switch 20 on the motive
component. That switch 20 may be activated by a user by pressing
the push button or resilient area on the coupling component 82,
which in turn presses switch 20. Alternatively, coupling component
82 may include one or more apertures or cut-out areas that allow
access to the control switches on the motive component.
[0074] While the exemplary embodiment of coupling component 82 is
depicted as a car, operable to "drive" when the hamster enters and
engages as previously described, other coupling components are
contemplated by, and within the scope of, the present invention. In
one exemplary embodiment the coupling component is an elevator
operable to move up and down when the hamster enters. The
elevator's drive mechanism may be driven by the wheels of the
motive component portion of the hamster, or may be separately
powered and activated upon detection of the hamster entering the
elevator. The elevator may be conjured in various whimsical shapes,
such as a carrot. The elevator coupling component may additionally
include mechanical interactive components such as gates or levers
that are operated by a user interacting with the coupling
component.
[0075] Another exemplary embodiment of the coupling component 82 is
configured as a pizza shop having a conveyor belt, ceiling fan,
advertising sign, or other movable component geared together and
driven by the motive component's drive wheels. This embodiment may
also include levers and gates allowing mechanical interaction by a
user to control the hamster entering or exiting the pizza shop.
[0076] Other exemplary embodiments of the coupling component 82 may
be configured as, for example, a beauty having a movable fan inside
a hair dryer, a toll booth having movable gate and movable stop-go
sign, a drive-in movie having a movable conveyor belt displaying
moving scenes, a helicopter with movable rotor, an airport and
airplane having a movable prop, an ice cream shop having movable
window scenes and releasable gumballs that fall into a slide, and a
hamburger drive-in shop with movable waitresses that "skate" to the
customers. In all of these embodiments, the movement of the
coupling component is effected by using power from the drive wheels
of the hamster, or otherwise being activated by the presence of the
hamster as described above. In addition, other features are
contemplated, such as the drive wheels of the hamster turning a
small generator that in turn lights LEDs that provide light to
various features, such as stop lights, signage, etc. on the
coupling component.
[0077] The coupling components may thus derive power from the
motive component (e.g., from the drive wheels or power source) to
drive or move a portion of the coupling component. For example, a
helicopter coupling component may have a rotor driven by the drive
wheels of the motive component, or a pizza shop may have a conveyor
belt driven by the drive wheels, or powered by the batteries on the
motive component. In addition, the coupling components may include
their own power sources and drive mechanisms that are triggered by
switches or sensors activated by the motive component. For example,
an ice cream truck coupling component may have its own power source
to light LEDS and sound a jingle, activated by a shake switch or
other detection switch. Thus, when the hamster enters the ice cream
truck the switch detects the presence of the hamster (or the
movement of the ice cream truck by the hamster) and activates the
light and sounds. In this embodiment, the coupling component is not
powered directly by the motive component, but is self-powered and
simply detects movement or the presence of the motive component.
Other variations and configurations will be apparent to those
skilled in the art.
[0078] In another alternative embodiment, the motive component may
provide no microcontroller or integrated circuits, with the drive
mechanism moving the motive component along the pathways and to the
coupling components, with switches on the motive component
detecting obstacles or other environmental elements. In such an
embodiment, the coupling component activates the various movement,
sound or light features of the component based on detection of the
presence of the hamster or the hamster drive wheels driving the
movement of the coupling component as described above. In this
less-intelligent embodiment, the motive component operates as a
primarily mechanical component, moving along the pathways and to
various coupling components to activate the features of the
coupling components, with minimal or no intelligence embedded in
the motive component.
Operation
[0079] In operation, the motive component 10, pathway component 12
and coupling component 82 of the present invention interact to
provide an apparently intelligent, interactive toy resembling a pet
hamster exploring its habitat and moving beyond its habitat by
traveling in a car. As the motive component travels through various
pathway components, bump codes formed in the pathway components are
detected by bump code sensors 34a, 34b and decoded by the control
circuitry. The decoded bump code is correlated to one or more
desired sounds, actions, or combinations of sounds and actions, and
the control circuitry commands those sounds and actions to take
place. For example, the motive component 10 can drive onto the
coupling component 82 to engage and move with the coupling
component so as to appear to be driving the car.
[0080] The toy may comprise multiple motive components or hamsters,
each having a different appearance and each being programmed to
respond differently to the codes embedded in the pathway component
and/or coupling component. In this manner, each of the hamsters
will have its own personality and react differently to the
environmental elements.
Alternative Exemplary Embodiment
[0081] Another alternative exemplary embodiment of an intelligent
interactive toy in accordance with the present invention is
depicted in FIGS. 11 through 17. In this exemplary embodiment, a
motive component 100 comprises a chassis 114, which houses control
circuitry and batteries in a manner similar to that described above
with respect to the first exemplary embodiment, and supports a
drive mechanism 116, with a decorative cover 118 resembling a pet
dog positioned over and covering the top portion of the chassis. An
auxiliary component 120 resembling a ball cap is removably engaged
with the top portion of the cover, with a portion of the cap
further engaging control circuitry contained therein as will be
described in more detail below. The removable auxiliary component
120 can thus provide direction to the control circuitry to affect
operation of the motive component, with different auxiliary
components able to direct different operations.
[0082] As best seen in FIG. 11, cover 118 is configured to resemble
a pet dog standing upright, having hands, feet, eyes and nose.
Control switches (described in more detail below) in communication
with the control circuitry are positioned on or embedded under
cover 118 such that the switches can be activated through the cover
by pressure applied to the corresponding area of the cover.
Preferably, the control switches are activated by a user pressing
the corresponding area of the cover or by the action of the motive
component engaging a surface or bumping into an object or obstacle
during movement in its habitat or environment. Operation or
activation of each control switch provides a signal to the control
circuitry which directs the operation of the motive component
accordingly.
[0083] An exemplary auxiliary component 120 resembling a baseball
cap is depicted in FIG. 15. The auxiliary component is configured
with a shell 122 and extending bill 124, having an inner surface
126 configured to conform generally to the shape of the head
portion of the motive component. A generally cylindrical peg 128
extends downwardly from the inner surface of the cap, the peg
configured to insert into, and engage with, a corresponding
aperture in the head portion of the motive component, and further
configured to engage with and activate a "hat" switch positioned in
the aperture, as discussed in more detail below. In this exemplary
embodiment one auxiliary component or hat has a single peg.
Preferably various other auxiliary components will be provided
having up to three pegs in three locations (corresponding to three
apertures in the head of the motive component) with the various
combinations of pegs defining seven distinct hat peg patterns, with
a "no pegs" pattern corresponding to a "no hat" condition because
without pegs the hat cannot activate the corresponding hat switches
located on the motive component.
[0084] Looking to FIGS. 12 and 13, motive component 100 includes
three generally cylindrical apertures 128a, 128b, 128c in the head
portion of the cover, the apertures extending downwardly into the
cover from the outer surface of the head. A "hat" switch 130a,
130b, 130c is positioned adjacent the lower end of each aperture so
that a peg extending from a lower surface of a hat as described
above will engage with and activate the corresponding switch.
[0085] With three hat peg apertures in the head of the motive
component, and three peg positions on the hat coupling component,
seven separate hat patterns are defined, with the eighth pattern of
no pegs corresponding to no hat. Any given hat having a specific
peg pattern, positioned on the head of the motive component with
the pegs inserted into the corresponding apertures, will thus
activate a specific combination of hat switches which in turn are
interpreted by the control circuitry to perform corresponding
actions and/or sounds.
[0086] For example, a baseball hat placed on the motive component
may have a single peg in the position corresponding to hat switch
#1, 130a. The control circuitry, detecting that hat switch #1 is
activated, may move the motive component in a manner simulating
running, and play baseball-related sounds. Similarly, a cowboy hat
may have two extending pegs, corresponding to hat switches #1 and
#2, 130a and 130b. The control circuitry, detecting that those two
hat switches are activated, may move the motive component in a
constant forward direction to drive an implement coupled with the
motive component (as discussed in more detail below) and play
associated sounds, for example, the sound of a tractor running. It
will be apparent to those skilled in the art that the three hat
switches provide seven distinct hat patterns to a given motive
component, with the eighth pattern corresponding to no activated
switches, indicating no hat in place. It should also be apparent
that different motive components may provide different actions in
response to the same hat. For example, a dog motive component may
perform specific movements and sounds in response to being coupled
with a cowboy hat, while a different motive component, such as a
cat, may provide different movements and sounds in response to
being coupled with the same cowboy hat. Thus, while the auxiliary
component (i.e., hat) provides information to the motive component
identifying the type of coupling component, different motive
components may be programmed through the control circuitry to
provide different reactions to that same auxiliary component. It
will also be apparent that other types of auxiliary components may
be implemented either in place of, or in combination with, the
auxiliary component as just described. For example, an auxiliary
component resembling a baseball bat may engage with and activate a
switch in the hand portion of the motive component, with the
control circuitry performing specific actions or sounds in
response. That baseball bat auxiliary component may also be
detected in combination with a hat auxiliary component as just
described to provide further combinations of motive component
actions and sounds. Similarly, an auxiliary component resembling a
baseball uniform may be fitted over the front of the motive
component in a manner to engage with and activate a switch along
the front body portion of the motive component with the control
circuitry performing specified actions or sounds in response. These
and other variations and combinations are within the scope of the
present invention. Devices other than switches may also be used to
detect the presence of the auxiliary component, such as RFID tags
or other identification means known in the art.
[0087] Preferably, motive component 100 includes a switch 132
positioned in the chest area of the component that signals the
control circuitry to operate in an "explore" mode, and also serves
as a "try me" switch activated by a user to initiate a
demonstration mode when the toy is packaged for display or sale,
and also includes a toe bump sensor switch 134 positioned at the
lower front area or the component operable to detect contact with
obstacles when the component is in motion. Preferably, a three
position power switch is accessible on the bottom of the chassis to
allow power to the component to be turned off or on, and also to
provide a "demo" mode in which the control circuitry operates the
motive component to demonstrate all of the movement, sound, and
other capabilities of the device.
[0088] Similar to the chassis described above with respect to the
first exemplary embodiment, chassis 114 includes a drive mechanism
116 operable to transport motive component 100 in forward or
reverse directions. Apertures 115 in the chassis allow the chassis
to be fastened to the cover 118.
[0089] Drive mechanism 116 preferably comprises a direct current
motor in mechanical communication with wheels 117a, 117b so that
rotation of the motor rotates the wheels to transport the motive
component forward or backward. The motor is in electrical
communication with the control circuitry which provides power to
the motor, with the capability to switch the polarity of the
command signal to drive the motor in either a forward or reverse
direction. Most preferably, wheels 117a and 117b are approximately
the same size so that forward rotation of the motor drives each
wheel equally such that the motive component moves in a
substantially straight path in forward and reverse. A switch 133 on
the bottom of the chassis is operable to detect contact of the
motive component with a surface, and directs the control circuitry
to disable power to the drive mechanism if it is not in
contact.
[0090] In other variations of this exemplary embodiment, the motive
component 100 may include bump code sensors operable to detect bump
codes in pathway components as previously described.
[0091] Similar to the control circuitry described previously, FIG.
17 depicts a block diagram of control circuitry of the alternative
exemplary embodiment. The control circuitry includes a
microcontroller 140 operable to execute programmed instructions, to
monitor inputs and control outputs according to those programmed
instructions, and to generate sound signals. Micro controller 140
may be any microcontroller known in the art having the capabilities
to perform the functions described herein. Preferably,
microcontroller 40 includes onboard Read Only Memory (ROM) 142,
Static Random Access Memory (SRAM) 144, and a Programmable Sound
Generator (PSG) having a Pulse Width Modulated (PWM) Digital to
Analog Converter (DAC) 146.
[0092] Read Only Memory (ROM) 142 stores the program code and
instructions that are executed by the microcontroller which defines
the operation of the motive component. ROM 142 also stores the
audio data files used by the microcontroller to generate sounds.
Preferably the audio data files are in ".wav" format, although
other audio file formats known in the art may equally be used with
appropriate decoding software running on the microcontroller. ROM
142 may also store any other programming, audio, data, or
configuration parameters as required. As is known in the art, ROM
142 provides essentially permanent storage of the program code,
audio data files, and other data or instructions stored thereon,
retaining that data even when no power is applied to the ROM.
Static Random Access Memory (SRAM) 144 provides temporary storage
for data and variables generated by and used by the microcontroller
as the program executes. As is known in the art, SRAM 144 stores
data only when power is applied.
[0093] Programmable Sound Generator (PSG) and Pulse Width Modulated
(PWM) Digital to Analog Converter (DAC) 146 provides the capability
to convert audio data to an electrical signal, as is known in the
art. The electrical signal is transmitted to speaker 148 which
converts the electrical signal to an acoustical wave, preferably in
the form of a human-perceptible sound. Speaker 48 is preferably a
miniature Mylar speaker positioned on the chassis 14 of the motive
component as described above. Of course other types of speaker
devices, such as piezoelectric transducers, may also be used.
[0094] Microcontroller 140 controls motor 150 through lines 152a,
152b that provide a voltage and current output to the motor. Motor
150 is the direct current motor portion of the drive mechanism 116
portion of the motive component as described above. Microcontroller
140 is operable to switch the polarity of the signals provided
through lines 152a, 152b to drive the motor in either the forward
or reverse directions to control the movement of the motive
component.
[0095] Switches 132 and 134 (corresponding to the toe and chest
portions of the cover 118 as described above) provide inputs to
microcontroller 40 indicating operator input or input due to
contact of the motive component with an obstacle. For example,
activation of switch 132 corresponds to the toe switch of the
motive component, indicating that the motive component has bumped
into an obstacle. Hat switches 130a, 130b, and 130c, correspond to
the hat switches positioned in the apertures in the head portion of
the motive component as described above, with the switches operable
to detect an auxiliary component engaged with the motive component
as also previously described. Bottom switch 133 is operable to
disable the drive mechanism, preferably by cutting power to the
motor, when it detects that the motive component is not in contact
with a surface, such as when the motive component is picked up by a
user, or if the motive component falls over.
[0096] Power to the microcontroller is preferably provided by at
least one AAA size battery positioned on the top side of chassis
114. Of course other power sources, such as rechargeable cells or
batteries and storage capacitors may also be used.
[0097] Microcontroller 140 is preferably a single integrated
circuit (IC) having all of the functionality of the ROM 142, SRAM
144, and PSG/PWM DAC 146 on-board and built-in. However, other
arrangements, configurations, and variations are within the scope
of the present invention. For example, the ROM, SRAM, and DAC could
each be discrete components controlled by a discrete microprocessor
IC. Or the PSG/PWM DAC and speaker functionality could be built or
combined into a separate device.
[0098] In operation, the alternative exemplary embodiment motive
component is turned on, and engaged with an auxiliary component
(i.e., a hat) as depicted in FIG. 16. In free-run mode, the motive
component will travel through its environment, detecting obstacles
via toe switch 117b and reversing or changing directions in
response. In addition, the motive component may engage with and
move a coupling component, such as the tractor 16 depicted in FIG.
16, so that the motive component appears to be driving the tractor
in a manner similar to that described above with respect to the
first exemplary embodiment hamster driving the car coupling
component.
[0099] Thus, as can be seen from the above-described exemplary
embodiments, the interactive intelligent toy of the present
invention provides a realistic, interactive toy that appears to
explore and react to its environment and habitat by responding to
the codes of the various pathways, rooms, and the like that it
encounters in its habitat. The overall effect of the movement and
reaction to its environment gives the appearance of an actual pet,
for example, exploring its environment in an intelligent,
interactive manner. Additional user-operable input switches also
allow a user to interact with the motive component, such as by
pressing the switch on the pet's chest. Furthermore, through the
use of the coupling and auxiliary components, the same motive
component can perform different activities.
[0100] The term "substantially", "generally", or "approximately" as
used herein may be applied to modify any quantitative
representation which could permissibly vary without resulting in a
change in the basic function to which it is related. For example,
wheels 26a, 26b are described as being approximately the same size
but may permissibly vary from that if the variance does not
materially alter the capability of the invention.
[0101] While the present invention has been described and
illustrated hereinabove with reference to various exemplary
embodiments, it should be understood that various modifications
could be made to these embodiments without departing from the scope
of the invention. For example, the specific drive mechanism,
control mechanism and power source for the motive component can
comprise any means known in the art to move, control and power the
component. Similarly, even though the exemplary embodiments include
a motive component, it is also anticipated that the intelligent
element may not have a drive mechanism, but may have a control
mechanism and power source. The intelligent element may still
interact with an environmental element by responding with sound,
lights or other actions upon being placed in contact or proximity
to the environmental element. In addition, the intelligent element
may provide control and/or power to a coupling component wherein
the coupling component has a drive mechanism.
[0102] It should be understood that the intelligent element or
motive component could be configured to resemble different animals,
people, vehicles or other characters, with the corresponding
environmental elements configured to resemble related environments,
habitats and objects. The intelligent element could, for example,
be a fireman with a pathway component consisting of a firehouse,
roads and homes and a coupling component consisting of a fire
truck. Similarly, the auxiliary components may be configured to
resemble hats as described above, or may be configured as other
articles of clothing, implements, or the like.
[0103] Therefore, the invention is not to be limited to the
exemplary embodiments described and illustrated hereinabove, except
insofar as such limitations are included in the following
claims.
