A wide variety of potential embodiments will be more readily understood through the following detailed description of certain exemplary embodiments, with reference to the accompanying exemplary drawings in which:
Humans have been domesticating animals, perhaps since pre-historical times. Today, domesticated animals generally can provide many services, including, for example, providing object retrieval, physical access, motive power, directional guidance, help beckoning, balance maintenance, hazard awareness, medical condition alerting, detection, protection, hunting, tracking, herding, socialization, companionship, entertainment, etc., any of which ultimately can tend to benefit one or more humans. Such animals potentially can include certain dogs, such as service dogs, guide dogs, assistance dogs, contraband detection dogs, tracking dogs, companion dogs, pet dogs, etc., and although less commonly, possibly can include certain other domesticated and/or trainable animals, such as animals generally recognized as cats, pigs, goats, sheep, horses, chimpanzees, dolphins, porpoises, falcons, pigeons, etc.
Desired behavior in many animals, whether domesticated or non-domesticated, can be encouraged and/or motivated by providing a reward, such as an edible treat, to the animal upon the animal's demonstration of the desired behavior. When a rather complex behavior is desired, the requester can break down the complex behavior into simpler behavioral elements, and can reward the animal for demonstrating any of those elements, until they are substantially learned and/or mastered. Then, multiple mastered elements can be requested in series until the series as a whole is substantially learned and/or mastered, and so forth, until the entire complex behavior is substantially learned and/or mastered. Similarly, to develop a desired behavior, the animal can be rewarded for demonstration of any behavior that to any selected degree approximates the desired behavior and/or one or more elements thereof.
In certain cases, a human is not able and/or does not desire to manually and/or directly dispense certain types of rewards to the animal. For example, a person who does not have adequate control over their hands might not be able to easily manually dispense a treat to a service dog (e.g., that is matched to that person) and thereby motivate and/or reward a trained and/or desired behavior from the service dog. As another example, a person walking a pet dog might not want to carry treats in their hand, pocket, and/or a treat pouch to manually dispense to the dog during the walk and/or might not want to contact the dog's mouth, tongue, and/or saliva. As still another example, a person riding in and/or driving a vehicle in which a domesticated animal is located and/or to which a service animal is attached (e.g., such as a horse-drawn wagon), might not desire and/or reasonably be able to dispense a reward to the animal to motivate, train, and/or reinforce a desired behavior. As yet another example, a person located remotely from an animal, such as a cat owner away at work while their cat is at home, a zookeeper safely located far outside of an animal's pen, and/or a wildlife manager located far away from a wild animal's feeding habitat, might be physically unable to directly and/or manually reward the animal.
For certain domesticated animals, a selected reward might be in the form of what is referred to herein as “kibble”, that is a foodstuff that can be animal-edible, relatively small (e.g., can have a largest dimension of from approximately 0.125 inches to approximately 2 inches (including all values and sub-ranges therebetween)), substantially dry, substantially hard, substantially brittle, processed, manufactured, coarsely ground, meal-based, cereal-based, and/or grain-based, etc. Other foodstuffs, such as those that are natural, fresh, raw, live, unprocessed, substantially oily, substantially wet, etc., might be selected. Other rewards, such as objects that roll, bounce, move, shimmy, rattle, squeak, crunch, shine, glitter, etc., might be selected.
Kibble and certain other rewards (collectively referred to herein as “treats”) can have physical properties that can make machine-based dispensing challenging. For example, certain treats can have somewhat irregular and/or coarsely-textured dimensions and/or outer surfaces that can tend to promote flow resistance, such as bridging, jamming, clogging, and/or poor conveyance of the treat within certain types of dispensing equipment. In these situations, attempting to overpower the treat sometimes can result in its fracture and/or damage (which can lead to further problems, such as further flow issues and/or lower reward value) and/or can result in mechanical and/or electrical damage to the dispensing equipment.
For example, experimental attempts to control the flow of dog kibble from a gravity-fed dispenser using a linear solenoid-actuated horizontally-oriented knife gate-style “valve” resulted in bridging and clogging immediately upstream of the valve and/or fracture of the kibble. Experimental attempts to dispense the same type of kibble from a gravity-fed dispenser via a rotating cup attached to a horizontally-oriented motor shaft and located within a housing resulted in jamming of the rotation and/or fracture of the kibble.
Although applicant does not intend to be bound by any particular theory, applicant currently theorizes that these and/or other failures might have been due to the substantially hard and/or inflexible nature of the dispenser housings and/or the flow control mechanisms (e.g., the gate valve and the motor-rotated cup), coupled with the substantially hard, coarsely-surfaced, brittle, and/or inflexible nature of the kibble itself. More broadly, from a system perspective, the combination of the utilized dispenser components and the reward might have lacked sufficient flexibility, smoothness, and/or lubricity to accommodate the physical nature of that reward, somewhat analogously to the “between a rock and a hard place” euphemism. It is currently believed that such systemic challenges can extend to many, if not most, of the nearly infinite combinations of other envisionable types of dispenser housings, flow control mechanisms, kibble, treats, and/or rewards.
Yet based on empirical evidence, it is currently believed that one or more of these challenges can be substantially overcome by utilizing a dispenser as described herein, and/or a legal equivalent thereof, which can comprise, in certain exemplary embodiments:
Repository 1320 can receive, contain, and/or store a desired object, such as treats, pending motor-assisted, pneumatic-assisted, gravity-assisted and/or vibration-assisted feeding and/or delivering them to actuator 1340, which can actuate, such as upon demand of the wheelchair occupant and/or operator (and/or perhaps the animal and/or an information device, such as a smart phone, tablet computer, and/or robot, etc.) to convey objects received from repository 1320 via 1360 to receiver 1380, which can serve to prevent the objects from contacting the ground, being contaminated, staining a flooring, being crushed, rolling away, becoming lost, becoming a tripping hazard, being eaten by the intended recipient animal at an undesired time, and/or being eaten by an undesired animal, etc.
Note that due to the flexible, swivelable, rotateable, and/or adjustable configuration of the illustrated embodiment of apparatus 1300, the location of receiver 1380 with respect to wheelchair 1100, animal 1200, and actuator 1340 changes from
A signal to dispenser 3340 and/or a flow of current from power supply 3310 to dispenser 3340 can be directly and/or indirectly controlled via a human, such as by the wheelchair operator and/or occupant (and/or possibly even by animal 3200 and/or an information device) via a switch 3320 (or a combination of switches). Switch 3320 can be, for example, an analog switch, single-pole switch, single-throw switch, double-pole switch, double-throw switch, 3-way switch, 4-way switch, momentary-on switch, polarity reversing switch, push-button style switch, rotary switch, selector switch, joystick switch, proximity switch, pressure switch, temperature switch, tilt switch, ribbon switch, grasp switch, leaf switch, flex switch, tip switch, plate switch, cup switch, cap switch, knife switch, lever switch, toggle switch, rocker switch, key switch, string switch, timed switch, latched switch, wired switch, wireless switch, remote switch, keyboard switch, electronic switch, binary switch, touch-screen-activated switch, tactile feedback switch, manual switch, foot-activated switch, sip and puff switch, pillow switch, cheek switch, chin switch, retinal tracker-activated switch, and/or thought-activated switch, etc., such as, for example, the wired, analog, single-pole, single-throw, push-button style, tactile feedback, manual, Tash MicroLight switch, available from AbleNet, Inc. of Roseville, Minn. In certain exemplary embodiments, switch 3320 can be, and/or can be actuated via, an information device, such as a MacBook, Mac Mini, iMac, iPod Touch, iPhone, and/or iPad, each available from Apple Inc. of Cupertino, Calif.
Current that flows from power supply 3310 can flow through a connecting wire (such as 24 AWG, 2 stranded conductor wire, which can be obtained via part number 100280 from Jameco Electronics of Belmont, Calif.), to activate an annunciator 3330, which can make a sound audible to animal 3200 and/or the human, thereby signifying that switch 3320 has been closed, preparing the animal for the reward, and/or providing even more rapid feedback to the animal than the reward itself. Exemplary annunciators can function and/or be constructed and/or be marketed as standard and/or piezoelectric buzzers, sirens, speakers, etc., and/or can include any of models 336225, 1956750, 1956661, 2098654, 336049, 123538, 336049, 335695, and/or 336997, which can be obtained from Jameco Electronics of Belmont, CA. Alternatively, the sound of the dispenser operating can provide sufficient feedback to the animal.
Electrical current that flows from power supply 3310 can power an electrically powered flow control mechanism and/or actuator, such as a linear solenoid, rotary solenoid, vibrator, AC induction motor, AC synchronous motor, stepper motor, brushed DC motor, brushless DC motor, coreless DC motor, pancake DC motor, universal motor, servo motor, linear motor, and/or electrostatic motor, that can be substantially located, for example, within dispenser 3340, such as within a dispensing portion 3360 of dispenser 3340. In the case of a linear solenoid, applied electrical power can be converted to linear motion of the solenoid's core, which can actuate a knife gate, plunger, and/or rack & pinion, etc. In the case of a rotary solenoid, applied electrical power can be converted to rotary motion of the solenoid's core, which can actuate a rotary cup, disk, scoop, flapper, auger, and/or screw, etc. In the case of a vibrator, applied electrical power can be converted to a vibrating mechanical motion, such as of dispenser 3340, repository 3350, and/or dispensing portion 3360. In the case of most motor types, applied electrical power can be converted to a rotation of the motor's output shaft (and/or the output shaft of a coupled gearbox, coupling, etc.), which in turn can rotate, for example, a cup, disk, scoop, flapper, auger, and/or screw that ultimately can tend to cause treats supplied by repository 3350 to move toward chute 3370, which can deliver one or more treats to receiver 3380, where the treats can be received, eaten, enjoyed, etc. by animal 3200.
Apparatus 3340 can be releaseably, removeably, and/or non-destructively mechanically coupled, mounted, and/or attached to a desired surface and/or thing, such as wheelchair 3100, a vehicle, a bicycle, a bed, a table, a wall, etc., via attachments 3390, which can be tape, strings, wires, cable ties, hook & loop fasteners, etc., which can allow apparatus 3340 to be available when and/or where needed, such as when the occupant is in wheelchair 3100, yet removable for cleaning, repair, relocation, etc. Alternatively, apparatus 3340 can be non-releaseably, non-removeably, and/or destructively removeably mechanically coupled, mounted, and/or attached to a desired surface and/or thing.
In certain exemplary embodiments, a dispenser, such as a dispenser described herein, can be releaseably, removeably, and/or non-destructively mechanically and/or communicatively coupled to, mounted to, attached to, contained within, and/or integral to, a robot. By pairing a robot with a service animal, the service animal can assist the robot with accomplish tasks and/or responding to challenges for which the robot is otherwise ill-equipped. By equipping the robot with a dispenser, in response to “sensed” inputs, predefined machine instructions stored in and/or accessible to the robot can actuate the dispenser as needed to attempt to control and/or motivate the service animal. Thus, for example, a robot might actuate a dispenser to train and/or reward a service animal for assisting the robot, such as by:
For repository 4200, a 3″ cap 4220 (all fitting sizes presented as nominal diameter) can serve as a protective cover over a 6″ long section of 3″ pipe that can function as canister 4240, to which a 3″×1.5″ reducer 4260 can be coupled to direct contents of canister 4240 generally toward housing 4400, and to which can be coupled to a short section of 1.5″ pipe 4280 (which can serve to fluidly connect reducer 4260 to housing 4400 and/or allow housing 4400 to support the weight of canister 4240 and its connected fittings), such that via cap 4220, canister 4240, reducer 4260, and/or pipe 4280, the contents of canister 4240 can be substantially protected from spilling, contamination, weather, and/or premature access by the animal and/or other animals, etc.
For housing 4400, a 1.5″ pipe cap 4410, which can serve to close one end of housing 4400, can couple via a short section of 1.5″ pipe and/or a 1.5″ plug (modified as needed to accommodate the fittings it is intended to couple, such as by grinding down as needed its lip, extensions, and/or protrusions, etc.) to a 1.5″ long coupling 4420, which can couple in a similar manner to another 1.5″ long coupling 4430, which can couple in a similar manner to a 1.5″ short coupling 4440, which can couple in a similar manner to another 1.5″ short coupling 4450, which can coupled in a similar manner to a 1.5″ tee 4460. Any of the just-mentioned couplings can serve to substantially surround certain components of dispensing apparatus 4000. The branch of tee 4460 can be coupled to reducer 4260 of repository 4200 via pipe section 4280. The longer straight-through portion of tee 4460 can couple in a similar manner to a 1.5″ 90 degree elbow 4470. Tee 4460 can serve to substantially surround and/or contain an auger and/or other actuator of the dispensing apparatus, convert substantially vertical treat flow direction to a substantially horizontal flow direction, and/or merge and/or couple an actuator portion of housing 4400 with a treat conveyance portion, etc. Elbow 4470 can direct treats from auger and/or actuator portion of housing 4400 to a chute 4480 and/or treat conveyance portion, transfer the weight of the treat conveyance portion to the actuator portion (and thereby to any attachments of housing 4400 and/or dispensing apparatus 4000). The generally downward projecting end of elbow 4470 can couple in a similar manner to chute 4480, which can serve to direct treats from the actuator (e.g., cup, disk, scoop, flapper, auger, and/or screw, etc.) to repository 4200, fluidly and/or mechanically couple the horizontal portion and/or actuator portion of housing 4400 to repository 4200, and/or mechanically support the weight of repository 4200. Chute 4480 can be formed from a 1.5″ 60 degree elbow and/or to 1.5″ 45 degree elbow coupled in a similar manner to a 1.5″ 22.5 degree elbow, which can couple in a similar manner to a 1.5″ adapter 4490 having a threaded end portion and a corresponding nut. The terminal and/or threaded end portion of adapter 4490 can protrude through an approximately 1.5″ hole in the side of a 4″ pipe cap (which can serve as a bowl and/or treat receiver 4500), and the corresponding nut can serve to secure the cap to the adapter, thereby coupling treat receiver 4500 to an outlet of housing 4400.
Any of the various fittings of dispensing apparatus 4000 can, in various exemplary embodiments, destructively, non-destructively, slideably, threadable, rotateably, non-rotateably, adjustably, rigidly, fixedly, glueably, resistively, disassemblably, releaseably, and/or non-releaseably couple via unglued, glued, caulked, and/or taped slip joint, threaded joint, locked joint, loose fit, slip fit, close fit, threaded fit, running fit, force fit, locked fit, and/or press fit, etc. Any of the resulting mechanical connections can be resistant to assembly, assembled, locked, released, non-adjustable, linearly adjustable, rotationally adjustable, angularly adjustable, positionally adjustable, rotated, rotateable, resistant to disassembly, destructively releaseable, non-destructively releaseable, destructively disassembled, and/or non-destructively disassembled, etc. Surface roughening and/or thread tape can be applied to one or more fitting surfaces located within and/or that form a threaded and/or slip fit joint to help secure that joint from, and/or increase resistance of the joint to, inadvertent and/or undesired disassembly. Glue, caulk, and/or tape or the like can be applied to one or more interior and/or exterior fitting surfaces located at and/or near a joint to help secure that joint from, and/or increase resistance of the joint to, inadvertent and/or undesired disassembly. One or more pins and/or screws can penetrate and/or impose on one or both coupled fittings to help releaseably lock and/or secure a joint from, and/or increase resistance of the joint to, inadvertent and/or undesired disassembly. Certain exemplary embodiments can provide the ability to non-destructively adjust a joint when desired, such as to change an orientation of all and/or a portion of the apparatus. Certain exemplary embodiments can provide the ability to non-destructively disassemble a predetermined joint when desired, such as to clean one or more fittings, clear a treat jam, adjust an auger dimension and/or shape, and/or adjust, optimize, repair, and/or replace mechanical and/or electrical components, etc. In certain exemplary embodiments, two or more fittings described above and/or herein can be implemented as a single, combined, unitary, and/or monolithic component.
Jack 4330 can be electrically coupled to an annunciator 4340, which can be used for purposes described herein, and/or which can be electrically coupled to a motor 4350, such as a direct current (DC), reversible, and/or gearhead motor, which: can operate at a voltage of approximately 6 volts to approximately 30 volts, including all values and sub-ranges therebetween, such as approximately 6 volts to approximately 15 volts, approximately 9 volts to approximately 12 volt, etc.); can rotate its output shaft at a relatively low angular speed (e.g., approximately 2 rpm (revolutions per minute) to approximately 400 rpm, including all values and sub-ranges therebetween, such as approximately 30 rpm to approximately 300 rpm, approximately 51 rpm to approximately 202 rpm, etc.); and/or can provide via its output shaft a relatively high torque at maximum efficiency, (e.g., approximately 50 g-cm to approximately 10000 g-cm, including all values and sub-ranges therebetween, such as approximately 350 g-cm to approximately 2200 g-cm, approximately 600-1300 g-cm, etc.); such as, for example, a Jameco Electronics model 161382, 155855, and/or 161374.
Motor 4350, which can be used to convert electrical power to rotating mechanical power, can be mounted to a partition 4360, which can be similar to partition 4320 in composition, structure, dimensions, and/or general function. Partition 4360 can secure motor 4350 to housing 4200, thereby preventing motor 4350 from rotating instead of and/or in addition to its output shaft and/or thereby encouraging the output shaft of motor 4350 to rotate with respect to the housing of motor 4350.
Mechanically coupled to motor 4350 can be an actuator, such as a cup, disk, scoop, flapper, auger, and/or screw. For example, motor 4350 can be mechanically coupled to an auger 4360, which can be formed from, for example, a single-conductor electrical cable (e.g., 12/1 AWG Romex), multi-conductor electrical cable (e.g., 14/2 AWG Romex), multi-conductor insulated telephone cable, co-axial cable television cable, Ethernet Category 5 networking cable, IEEE 1394 (Firewire) serial computer device cable, USB cable, video cable, hose, tube, plastic pipe, and/or polymeric material, elastomeric material, wire, etc. In certain exemplary embodiments, auger 4360 can be cut, extruded, stamped, tooled, formed, manually shaped, and/or coiled into a desired shape, and/or can be manually re-shaped as desired. In certain exemplary embodiments, auger 4360 can substantially resemble a helical spring and/or can possess a moderate degree of shape memory, thereby allowing it to moderately flex, yet return to a predetermined formed and/or coiled shape, in response to certain forces that can be applied to it by motor 4350 and/or the treats. Auger 4360 can define a longitudinal and/or rotational axis, which, in operation, can be oriented substantially horizontally, substantially diagonally, and/or substantially vertically. In certain exemplary embodiments, auger 4360 can define an open core, thereby allowing treats to reside within the inner circumference and/or outside the outer circumference of auger 4360, which can increase the surface area of auger 4360, provide a larger cross-section flow area for the treats, allow auger 4360 to flex more easily, decrease any tendency of auger 4360 to crush the treats, decrease jamming of auger 4360 and/or motor 4350, etc. Auger 4360 can define a plurality of uniform and/or non-uniform coils. That is, in certain exemplary embodiments, lengthwise along any given coil, the inner diameter can vary, the outer diameter can vary, the pitch can vary, and/or the thickness of auger 4360 can vary, and/or any of those variations can be applied and/or changed manually, which can allow auger 4360 to be dimensioned, adjusted, repaired, and/or optimized to accommodate changes and/or variations in sizes, quantities, densities, types, and/or mixtures of treats; changes and/or variations in coiled and/or uncoiled auger lengths; changes and/or variations in housing diameters and/or one or more dispenser dimensions; changes and/or variations in auger and/or housing materials of construction; etc. In certain exemplary embodiments, auger 4360 can be substantially formed, covered, sheathed, and/or jacketed by a substantially electrically non-conductive, non-metallic, and/or polymer material, which can protect auger 4360 from abrasion by treats, control friction between auger 4360 and the treats it can convey, and/or protect auger 4360 from abrasion caused by contact with the housing and/or any component thereof.
Auger 4360 can comprise one or more members (“backbones”) that can be manually malleable, electrically conductive, and/or metallic, and/or which can allow the shape of auger 4360 to be relatively easily manually adjusted to a desired shape yet provide auger 4360 with a desired degree of shape memory, which can allow auger 4360 to substantially retain and/or return to the desired shape in response to treat- and/or motor-generated forces, facilitate clearing treat jams, and/or allow changing and/or optimizing the length of auger 4360, diameter(s) of one or more of its coils, widths of one or more its coils, and/or spacing(s) and/or pitch of one or more its coils.
When auger 4360 comprises more than one backbone, each additional backbone can add additional strength, flexibility, shape memory, and/or fatigue resistance to auger 4360. Moreover, each of those backbones can be substantially parallel. That is, the backbones can have similar shapes and/or exhibit a substantially uniform spacing with respect to each other along the length of auger 4360, so that auger 4360 can function, in at least some respects, as a single-flighted and/or single-backboned auger despite having multiple “internal” flights and/or backbones.
Any of the backbones of auger 4360 can be individually covered, sheathed, and/or jacketed by a polymer material, which can help prevent and/or lessen contact between the backbones, lower friction between the backbones, maintain relative positioning of the backbones within auger 4360, maintain parallelism of the backbones, maintain a substantially uniform spacing between the backbones along the length of auger 4360, etc.
Relative movement and/or rotation of auger 4360 with respect to housing 4400, can cause apparent motion of the (outer, external, apparent, single, and/or combined) flight of auger 4360 substantially in direction R (although the opposite rotation and apparent motion is also possible), which can urge treats received from repository 4200 toward chute 4480 and/or receiver 4600, where the treats can be retrieved by the animal.
Power supply 5100 can be electrically coupled to a switch 5220, such as a single-pole, single throw, (On)-Off-(momentary-On) switch, which, via its manual activation, can allow a user to temporarily electrically activate, turn on, and/or allow current to flow to, motor 5400. In certain exemplary embodiments, switch 5220 can be a double-pole, double throw, (On)-Off-(On) (e.g., momentary-On, momentary-Reverse) switch, which, via its actuation, can allow a user to reverse current direction, thereby causing the output shaft 5460 of motor 5400 to reverse its direction of rotation, which can be helpful for clearing treats that have jammed within auger housing 5620. In certain exemplary embodiments, switch 5220 can comprise a serial combination of switches, such as a single-pole, single throw, momentary-on switch electrically coupled in series with a double-pole, double throw, On-Off-On switch, where the single-pole switch is normally used for electrically activating motor 5400, and the double-pole switch can be changed from one On position to the other to reverse the rotational direction of output shaft 5460 upon temporary manual actuation of the single-pole switch.
Even when manually rewarding an animal for demonstrating a desired behavior and/or approximation thereof, there can be at least a small time delay from the time a human seeks to reward the animal and the time the reward is actually presented to the animal. The longer that delay, the greater can be the attenuation in the animal's association of the reward with the desired behavior. That is, the slower the delivery of the reward, the less likely the animal might be to link the reward with the desired behavior, and the more training that might be needed to create that link. To help alleviate and/or reduce that issue, the human can provide a predetermined sound promptly upon recognition that the animal has performed and/or approximated the desired behavior, and then can follow-up shortly thereafter by presenting the reward. The sound can signal to the animal that the animal has performed a desired behavior, and/or that a reward will come relatively soon. This approach can be effective when the sound can be generated considerably quicker than the reward can be delivered, which can be the situation in the case of certain exemplary embodiments.
That is, certain exemplary embodiments can manifest a delay from the time the human and/or operator actuates the switch to activate motor 5400 until the treat is presented to the animal. In certain exemplary embodiments, coupled electrically in series with motor 5400 can be one or more annunciators 5260, as described herein, which can serve to, in normal operation, make a predetermined noise when electrically activated. This noise can notify the human that switch 5220 has been actuated, alert the animal that a treat will soon follow, thereby allowing the human to more closely temporally link the animal's desired behavior with the reward, cause the animal to position itself to retrieve the treat, and/or promptly reinforce the desired behavior.
Motor 5400 can comprise a motor portion 5420 that is adapted to convert electrical energy to mechanical rotation, and/or a gearhead portion 5440 that is adapted to reduce the angular speed of that rotation, which can help prevent dispensing too many treats, dispensing treats too rapidly, damaging treats and/or dispenser components, etc. Thus, although motor portion 5420 can rotate at, for example, 1800 rpm, 3600 rpm, and/or 7200 rpm, etc. (including any value and/or subrange therebetween) in normal operation, the output shaft 5460 of gearhead portion 5440 can rotate at, for example, 30 rpm, 60 rpm, 90 rpm, 150 rpm, or 240 rpm, etc. (including any value and/or subrange therebetween).
Gearhead portion 5440 of motor 5400 can be mechanically attached to a end portion 5540 of motor housing 5520 via one or more screws 5490 that each fit through a corresponding hole 5560 in end portion 5540 and into a corresponding hole in the body of motor 5400, thereby resisting relative motion between the body of motor 5400 and end portion 5540 and/or housing 5520. That is, in normal operation, when motor 5400 is activated, output shaft 5460 can rotate with respect to end portion 5540, motor portion 5420, and/or motor housing 5520.
A shaft coupling 5460, such as a model 138288 and/or 162270 from Jameco Electronics, can be used to mechanically couple output shaft 5440 to auger 5700, so that, in normal operation, auger 5700 tends to rotate when output shaft 5440 rotates. Shaft coupling 5460 can be substantially annular in shape, with the annular hole larger in diameter than the outer diameter of output shaft 5440, so that shaft coupling 5460 can easily fit over the outer diameter of output shaft 5440. Shaft coupling 5460 can also define a threaded set screw hole that can extend perpendicular to the annular hole, that is, from a outer circumferential side of shaft coupling 5460 to an inner side of shaft coupling 5460, and/or that is adapted to receive a set screw that can be used to securely fasten shaft coupling 5460 to output shaft 5440. That set screw can be replaced with a machine screw 5480 having a similar thread diameter and/or pitch. The shaft of machine screw 5480 can extend through a hole drilled and/or bored through auger 5700, and/or through a hole in a ring terminal that can be crimped onto an end of auger 5700. The length of the machine screw can be selected and/or adjusted so that machine screw 5480 can, in normal operation: threadably extend through the set screw hole of shaft coupling 5460, releaseably fasten shaft coupling 5460 to output shaft 5440, and/or releasably mechanically couple auger 5700 to output shaft 5440, so that when output shaft 5440 rotates, auger 5700 also tends to rotate in substantially the same rotational direction and at approximately the same angular speed.
Auger 5700 can comprise a plurality of coils that can have a uniform and/or non-uniform outer diameter, inner diameter, width, and/or inter-coil spacing. For example, the inner diameter D1 of coil 5710 can differ from the inner diameter D2 of coil 5720 and/or the inner diameter D3 of coil 5730, and/or the spacing 51 between coil 5710 and coil 5720 can differ with the spacing S2 between coil 5720 and coil 5730. Alternatively, a first sub-plurality of coils can have uniform outer diameter, inner diameter, width, and/or inter-coil spacing, and a second sub-plurality of coils can have non-uniform outer diameter, inner diameter, width, and/or inter-coil spacing. Moreover, because auger 5700 can be manually malleable, the outer diameter, inner diameter, width, and/or inter-coil spacing can be manually varied as desired, which can allow auger 5700 to be field-adjusted to accommodate, experiment with, and/or be optimized based on: changes and/or variations in sizes, quantities, densities, types, and/or mixtures of treats; changes and/or variations in coiled and/or uncoiled auger lengths; changes and/or variations in housing diameters and/or one or more dispenser dimensions; changes and/or variations in auger and/or housing materials of construction; etc.
Auger housing 5620 can define a substantially horizontally-oriented longitudinal axis B. In normal operation, a free end 5740 of auger 5700 can rotate freely, that is, without direct connection to any fixed element, yet generally can be substantially constrained in that rotation by auger housing 5620 such that free end 5740 rotates substantially about an auger core longitudinal axis that is substantially parallel to and/or co-axial with auger housing longitudinal axis B. Leaving free end 5740 substantially free can allow for simpler construction of apparatus 5000 and/or auger 5700, field adjustments to, experimentation with, and/or optimization of, the length, coil diameter, and/or coil spacing of auger 5700, easier resolution of treat jams, and/or easier cleaning of the interior of auger housing 5620.
In certain exemplary embodiments, power supply 5100 can provide electrical current to a panic alarm circuit 5300, which can comprise a panic switch 5320, such as a single-pole, single-throw, momentary on switch. In normal operation, to indicate and/or provide a local warning that panic switch 5320 has been activated, panic switch 5320 can allow electrical current to flow to an indicator light and/or to warning annunciator 5340, which can substantially immediately produce a sound at a moderate sound pressure level (e.g., approximately 70 dB to approximately 90 dB measured e.g., directly in front of and/or within approximately 6 inches of annunciator 5340) and/or at a sound pressure level sufficient to indicate and/or provide a local warning that panic switch 5320 has been activated. In normal operation, to allow sufficient time after warning annunciator has begun sounding to release panic switch 5320 and thereby to prevent panic annunciator 5380 from sounding, when activated, panic switch 5320 can allow electrical current to flow to delay timer 5360, which can allow electrical current to flow to panic annunciator 5380 after a predetermined and/or programmed delay time, such as a selected time between approximately 1 second and approximately 30 seconds (including all values and sub-ranges therebetween), such as approximately 3 seconds, 5 seconds, etc. When activated, panic annunciator 5380 can produce a relatively loud, distinct, and/or noticeable sound that can be sufficient to draw the attention of other humans to the general location of apparatus 5000 and/or the human and/or animal that activated its panic alarm. Such a panic alarm can be useful when the dispenser operator needs and/or desires particular attention and/or emergency assistance when an assistant and/or caregiver is pre-occupied, out of sight, and/or not immediately available. In certain exemplary embodiments, the panic alarm circuit and/or its switch can be adapted to be activated by the animal, such as upon verbal and/or visual prompting, and/or by an information device, under human and/or programmatic control.
Apparatus 8000 can comprise a switch 8100, such as described herein, which can be, for example, a single-pole, single-throw, momentary on, push button switch. In normal operation, switch 8100 can be mounted in and/or attached to a handle 8200, which can provide a surface via which a human can grip apparatus 8000, and/or which can be mechanically coupled as described herein, such as via a short section of pipe and/or a plug, to a reducer 8300, which can be mechanically coupled as described herein to an external housing 8400, which can be mechanically coupled as described herein to a reducer 8500, which can be mechanically coupled as described herein to a foot 8600, which can provide a ground-contacting member for apparatus 8000, and/or can bear the weight of apparatus 8000 and/or a human using apparatus 8000, etc.
In normal operation, a chute 8700 can be mechanically coupled as described herein to external housing 8400 and/or to receiver 8800 to direct treats from within external housing 8400 to receiver 8000. Any of handle 8200, reducer 8300, external housing 8400, reducer 8500, foot 8600, chute 8700, and/or receiver 8800 can, for example, be formed and/or function substantially as described herein, that is, can be formed primarily from, for example: schedule 10, schedule 20, and/or schedule 40; slip joint and/or threaded; metal, PVC, and/or other polymer; pipe, tubing, and/or conduit sections and/or fittings.
In certain exemplary embodiments, handle 8200, foot 8600, and/or chute 8700 can be formed from, for example, fittings having a nominal diameter and/or actual outer diameter of from approximately 0.375″ to approximately 2″, including all values and sub-ranges therebetween. External housing 8400 can be formed from, for example, fittings having a nominal diameter and/or actual outer diameter of from approximately 0.5″ to approximately 4″, including all values and sub-ranges therebetween. Receiver 8800 can be formed, for example, substantially as described herein, such as from a fitting, such as a cap, having a nominal diameter and/or actual outer diameter of from approximately 2″ to approximately 6″, including all values and sub-ranges therebetween. External housing 8400 can serve to contain treats within apparatus 8000; protect treats from spilling, contamination, weather, and/or premature access by the animal and/or other animals, etc.; protect the motor and/or other electrical components from weather, abuse, short circuits, causing electrical shock to a human and/or animal, etc.; connect handle 8200 to foot 8600; fluidly and/or mechanically couple the repository and/or canister portion of external housing 8400 to chute 8700, and/or mechanically support the weight of chute 8700 and/or receiver 8800. Chute 8700 can serve to direct treats from within external housing 8400 to receiver 8800, fluidly and/or mechanically couple external housing 8400 to receiver 8800, mechanically support the weight of receiver 8800, and/or protect treats from spilling, contamination, weather, and/or premature access by the animal and/or other animals, etc.
Internal housing 8950 and/or motor 8960 can be mechanically coupled, for example, substantially as described herein, to a support plate and/or partition 8940, which can be mechanically coupled, for example, substantially as described herein, to external housing 8400. Through partition 8940 can extend a hole sufficiently sized to accommodate an output shaft of motor 8960. Through partition 8940 can extend a hole 8945 sufficiently sized to, upon actuation of switch 8100, allow rewards and/or treats to pass substantially freely therethrough. Motor 8960 can be mechanically coupled, for example, substantially as described herein, to auger 8930, which can define a longitudinal and/or rotational axis that can be oriented substantially vertically. In normal operation, upon activation of motor 8960, auger 8930 can rotate, causing apparent motion of the (outer, external, apparent, single, and/or combined) flight of auger 8930 substantially in direction R (although the opposite rotation and apparent motion is also possible), which can thereby sufficiently disrupt and/or interrupt bridging and/or jamming of treats 8920 so that at least some treats can fall through hole 8945 before bridging and/or jamming resumes. In normal operation, upon deactivation of motor 8960 and/or cessation of rotation of auger 8930, a sufficient number of treats 8920 can bridge and/or jam to thereby reduce and/or eliminate the flow of treats 8920 through hole 8945. In an alternative embodiment, auger 8930 can be augmented by and/or replaced by a vibrator, pneumatic blaster, loudspeaker, linear solenoid, etc., that can temporarily disrupt bridging and/or jamming, thereby allowing at least some treats 8920 to fall and/or flow through hole 8945.
In normal operation, after falling through hole 8945, treats 8920 can impact and/or encounter a sloped ramp 8990, which can guide treats 8920 into chute 8700, and thereby into receiver 8800. Ramp 8990 can be formed, for example, from a piece of PVC pipe cut lengthwise to create a ramp-like and/or trough-like structure, and/or from a piece of vinyl siding that has been curled, angled, and/or trimmed to fit within housing 8400. In certain exemplary embodiments, ramp 8990 can be combined with chute 8700 to form a single, unitary, and/or monolithic component. In certain exemplary embodiments, chute 8700 can be eliminated and receiver 8800 can be directly connected to external housing 8400.
In certain exemplary embodiments, via one or more user interfaces 9600, such as a graphical user interface, a user can view a rendering of information related to researching, designing, modeling, creating, developing, building, manufacturing, operating, maintaining, storing, marketing, selling, delivering, selecting, specifying, requesting, ordering, receiving, returning, rating, and/or recommending any of the products, services, methods, user interfaces, and/or information described herein.
For example, via a user interface 9600, such as a touch screen, a user can enter a gesture that the information device can interpret as a request to send a signal to, for example, energize and/or activate a motor of a treat dispenser, reverse a direction of that motor, activate a vibrator that can vibrate an auger, treats, and/or housing associated with that motor and/or an apparatus, activate a timer, activate an annunciator, activate a circuit, delay activation, cancel activation, compose a communication, transmit a communication, retrieve a communication, gather data and/or information, store data and/or information, query data and/or information, display data and/or information, transmit data and/or information, actuate a still camera and/or a video camera, display a photo and/or video, actuate a sound recorder, and/or play a sound recording, etc.
For repository 10200, a 3″ cap 10240 (all fitting sizes presented as nominal diameter) can serve as a protective cover over an approximately 6″ long section of 3″ pipe that can function as canister 10220, to which a 3″×1.5″ reducer 10260 can be coupled to direct contents 10100 of canister 10220 generally toward chute 10400, and to which can be coupled to a 1.5″ coupling 10420 (which can serve to fluidly connect reducer 10260 to chute 10400 and/or allow chute 10400 to support the weight of repository 10200 and/or its associated and/or connected fittings), such that via cap 10240, canister 10220, reducer 10260, and/or coupled 10420, the contents 10100 of canister 10220 can be substantially protected from spilling, contamination, weather, and/or premature access by the animal and/or other animals, etc.
Chute 10400 can serve to direct contents 10100, such as treats, from repository 10200 to receiver 10600, and/or mechanically support the weight of repository 10200 and/or receiver 10600, such as when dispenser 10000 is suspended from a distinct structure, such as a wheelchair. Chute 10400 can be formed from, e.g., a 1.5″ coupling 10420, 1.5″ 45 degree elbow 10480, and/or 1.5″ adapter 10490, which can have a threaded end portion and/or a corresponding nut 10495. The terminal and/or threaded end portion of adapter 10490 can protrude through an approximately 1.5″ hole in the side of a 4″ pipe cap (which can serve as a bowl and/or treat receiver 10600), and/or the corresponding nut can serve to secure the cap to the adapter, thereby coupling and/or attaching treat receiver 10600 to an outlet of chute 10400.
Located within coupling 10420 can be a valve 10900, such as a rotary valve, which can serve to selectively allow, control, throttle, disrupt, impede, and/or prevent flow of treats through chute 10400. A groove extending through coupling 10420 can allow a torque arm of valve 10900 to be moved, such that at least a portion of valve 10900 is correspondingly moved to a desired rotational position.
