The present application is related to the following United States patent application Nos. U.S. patent application Ser. No. 15/130,135, entitled CHILD RESTRAINT SYSTEM; and, U.S. patent application Ser. No. 15/130,256, (now U.S. Pat. No. 10,042,358) entitled MOBILE APPLICATION FOR WHEELED JUVENILE PRODUCT which are incorporated herein by reference in their entireties.
Many juvenile products, such as bouncy seats and swings, include motors or other actuators for imparting a stimulation pattern in the form of a motion or vibration pattern that is enjoyable to the juvenile occupant. Such juvenile products typically have a limited number of preprogrammed motion or vibration patterns and/or speeds that the juvenile's caregiver can select through an interface on the juvenile product. Simple juvenile products have one motion pattern (e.g., back and forth swinging) at one or a couple different speeds. More sophisticated juvenile products have more preprogrammed motion patterns, with each having a number of different possible speed settings. For example, the mamaRoo® swing from Thorley Industries, d/b/a 4moms, is a swing with five different preprogrammed motion patterns, each selectable in one of five different speeds. The caregiver can select the desired preprogrammed pattern and speed combination through a control panel on the base of the swing.
In one general aspect, the present invention is directed to systems and method for defining a stimulation pattern for a juvenile product, such an infant swing, bouncer seat, crib, a stroller, etc., that has a juvenile-supporting structure (e.g., a seat) and at least one actuator (e.g., a motor) for imparting a motion or vibration on the juvenile-supporting structure. In various embodiments, the systems and methods utilize a mobile device, such as a smartphone or tablet computer, that executes a mobile application (a “mobile app”) that is linked to the juvenile product. The method can comprise the step of recognizing, by way of the mobile device executing the mobile app, the user-defined stimulation pattern for the juvenile product. The stimulation pattern can include a vibration pattern and/or a motion pattern for the juvenile product, and can be detected in a number of different ways by the mobile device, such as (i) the user drawing a motion pattern on a pressure-sensitive touchscreen of the mobile device, (ii) the user moving the mobile device in free space with the movements captured by motion-sensing elements of the mobile device, such as accelerometers, magnetometers, and gyroscopes, or (iii) by translating an audio waveform of a sound recording to a vibration pattern. The method further comprises the step of determining control signals for the actuator(s) of the juvenile product based on the user-defined stimulation pattern. The control signals can be computed by the mobile device, by the juvenile product, or by a remote server connected to the Internet, or by a combination thereof. The method further comprises the step of, in response to receiving a command to execute the user-defined stimulation pattern, controlling the actuator(s) of the juvenile product based on the stored control signals for the user-defined stimulation pattern, to thereby move the juvenile-supporting structure of the juvenile product in accordance with the user-defined stimulation pattern.
Various embodiments of the present invention can provide an efficient way for a caregiver to define a personalized stimulation pattern for the juvenile using the juvenile product. These and other potential benefits with various embodiments of the present invention will be apparent from the description that follows.
Various embodiments of the present invention are described herein by way of example in connection with the following figures, wherein:
In one general aspect, the present invention is directed to a “mobile app,” e.g., a software application that runs on a mobile device, such as a smartphone or tablet computer, that allows the user of the mobile app to define stimulation patterns for a juvenile product that is linked to the mobile device/app. The juvenile product can be an infant swing, a bouncer seat, a crib, a stroller, or any other suitable juvenile product with a juvenile-supporting structure on which the juvenile sits or lies, for example. The juvenile product comprises at least one actuator (e.g., a motor) that imparts a motion on the juvenile-supporting structure of the juvenile product. The motion could be as simple as a vibration, or motion in one, two, or three dimensions. Through the app, the user can define a stimulation pattern (e.g., a vibration or motion pattern) that is uploaded to the juvenile product in order to control the movement of the juvenile product (by controlling the actuator(s) thereof) according to the user-defined stimulation pattern.
In addition or in lieu of the WiFi capabilities, the mobile device 10 may comprise other types of wireless communication capabilities. For example, the mobile device 10 may comprise Bluetooth and/or Near-field Communication (NFC) circuitry 44, 46 that allows the mobile device 10 to communicate wirelessly via Bluetooth or Near-field Communication (NFC) channels, as the case may be, with a paired device, such as the juvenile product 12. In addition or alternatively, the mobile device 10 could posses other types of wireless communication capabilities, such as ZigBee, Z-Wave, or Wireless USB, for example, that allow the mobile device 10 to communicate wirelessly with the juvenile product 12 and/or the network 16.
As shown in
In addition, as shown in
The mobile device's memory 62 may include internal Random Access Memory (RAM), Read Only Memory (ROM), flash memory, and/or removable storage. The RAM may be, for example, LPDDR2 DRAM; the ROM may include one or more memory chips; the flash memory may include a SSD or emmc flash memory; and the optional removable storage may include a form of microSD card. One or more of these memory units may store the juvenile product mobile app 50, which is a software application that when executed by the processor 60 causes the processor 60 to capture and upload to the juvenile product 12 a stimulation pattern defined by the mobile device user via the mobile device/app.
The mobile device 10 may also comprise a microphone 39 that is connected to the processor 60. In that connection, the mobile device 10 may include an analog-to-digital converter (ADC) 41 to convert audio picked up by the microphone 39 to digital format for processing by the processor 60. The microphone 39 and the processor 60 may be in communication via an I2C data bus 43. The microphone 39 is valuable for programming a user-defined vibration pattern for the juvenile product 12 via the mobile app 50 using a sound recording, as described further below. Also as shown in
The juvenile product 12 may be any juvenile product that has at least one motor or other types of actuator 28 that imparts movement on the juvenile-supporting structure of the juvenile product 12, such as a motion pattern or vibration pattern, to soothe or otherwise mollify or pacify the juvenile that occupies the juvenile-supporting structure of the juvenile product 12. To that end, the juvenile product 12 could be a swing, a bouncer seat, a crib, or a stroller, for example, with a juvenile-supporting structure in which the juvenile sits or lies. As shown in
U.S. published patent application Pub. No. 2016/0058201, which is incorporated herein by reference in its entirety, describes a juvenile bouncer seat having a juvenile-supporting structure, e.g., a fabric covering around a frame, and a vibration motor that imparts vibrations to the frame to thereby vibrate the juvenile-supporting structure. Such a bouncer seat is an example of juvenile product 12 for which embodiments of the present invention could be used, with the vibration motor being an example of the actuator 28 shown in
As also shown in
The computer data network 16 can comprise the Internet, WiFi networks, LANs, WANs, etc. The mobile device 12 may connect to the computer data network 16 via a WiFi network or the mobile device's cellular network interface or any other suitable means. Similarly, a juvenile product 12 that is equipped with WiFi and/or a cellular network interface, for example, could connect to the computer data network 16.
A user of the mobile device 10 may download the mobile app 50 from the server 14. Also, in various embodiments, the server 14 may perform calculations related to the user-defined stimulation pattern, as described further below. Figure shows one remote server 14 for the sake of simplicity. The functions described herein for the remote server 14 may be distributed across multiple servers that are connected to the network 16. Those multiple servers could be co-located at a common data center, or could be at various locations on the network 16.
Next, at step 104, the mobile device user can define a stimulation pattern for the juvenile product 12 through the mobile device/app. There are a number of ways in which the mobile device user can define the stimulation pattern and the right-side of
At step 120, via a selection menu provided on the user interface 40 by the app 50, the mobile device user can select an input mode for defining the stimulation pattern. Exemplary stimulation pattern input modes that could be used with the mobile device/app include tapping a vibration pattern on the touch screen 40, drawing a stimulation pattern on the touch screen 40, moving the mobile device in free space to define a stimulation pattern, or creating or identifying an audio file whose waveform is translated to a corresponding vibration pattern for the juvenile product 12. The mobile app preferably knows what stimulation patterns the juvenile product is capable of and correspondingly only displays options for the mobile device user that are consistent with the capabilities of the juvenile product 12. For example, if the juvenile product 12 only has a vibration motor(s), the app 50 preferably only allows the mobile device user to define vibration patterns for the juvenile product 12, and not other types of stimulation patterns. Conversely, if the juvenile product 12 only has a motor(s) for moving the juvenile-supporting structure in one or more dimensions, and no vibration motors, the app 50 preferably only allows the mobile device user to define motion patterns for the juvenile product 12, and not vibration patterns. Of course if the juvenile product has both motion and vibration capabilities, the app 50 can allow the mobile device user to select either motion or vibration patterns or both. The mobile app 50 recognizes the capabilities of the juvenile product 12 because when the juvenile product 12 is paired with the app 50 during the registration process (step 102 of
Once the desired mode is selected, at step 122 the mobile device user can press or otherwise activate a “start” button or icon, or the like, on the app's display on the user interface 40 of the mobile device 10. Then, at step 124, the mobile device user can define the stimulation pattern. For a tapped vibration pattern input mode, the mobile device user can tap the mobile device's touch screen 52 according to the desired vibration pattern for the juvenile product 12. The taps can be long or short in duration, and can be spaced by desired time intervals. The touch pad circuitry 52 of the user interface 40 captures the duration, intensity, and timing of the taps, until the user presses or otherwise activates a “stop” button or icon, or the like, on the app's display on the user interface 40. Data indicative of captured vibration pattern is stored in the memory 62 and processed by the processor 60. At step 128, the mobile device 10 (executing the app 50) can replicate the recorded vibration pattern to see if it is acceptable to the mobile device user by activating its vibrator(s) 47 to replicate the recorded vibration pattern in terms of the duration, intensity, and timing of the taps. Alternatively or additionally, the processor 60 could activate one or more LEDs or other light sources of the mobile device 10 that blink on and off in concert with the recorded vibration pattern (LEDs on for vibration and off for periods of no vibration). Different LEDs colors could even be used for different tap intensities or durations, or combinations thereof. If the mobile device user approves the pattern, the mobile device user can press or otherwise activate an “accept” button or icon, or the like, on the app's display on the user interface 40 of the mobile device 10, which completes the mobile device user's definition of the new stimulation pattern. If the mobile device user is not satisfied, at step 132 the mobile device user can try again by pressing or otherwise activating a “re-do” button or icon, or the like, on the app's display on the user interface 40 of the mobile device 10, which restarts the process at step 120.
As another example, if at step 120 the mobile device user selects the “draw” input mode to draw a motion pattern on the user interface touch screen, then (i) at step 122 the mobile device user can hit the start button to (ii) at step 124 draw the desired two-dimensional motion pattern on the mobile device's user interface touch screen until (iii) the user hits the stop button at step 126. The mobile device user has to draw the pattern with an implement that is detectable by the touch screen 52. If the touch screen is a capacitive touch screen, the user can draw the pattern with an electrically conductive implement, such as the mobile device user's finger, for example. If the touch screen is a resistive touch screen, other types of implements (e.g., gloved fingers, stylus, etc.) could be used and detected by the touch screen 52. In any case, the touch screen 52 can capture (e.g., detect and record) the movement of the user's finger (for example) on the touch screen between activation of the start and stop buttons at steps 122 and 126. Data indicative of captured stimulation pattern is stored in the memory 62 and processed by the processor 60. The processor 60, executing the software of the app 50, can display the 2D pattern on the user interface 40 of the mobile device 10 after it is captured by the touch screen 52 so that the mobile device user can accept or reject the pattern at steps 128 to 132. The 2D stimulation pattern can be displayed on the mobile device by a lighting pattern, for example, that corresponds to or replicates the captured 2D stimulation pattern drawn on the touch screen 52 by the mobile device user at step 124.
Another input mode at step 120 is that the user could select to move the mobile device 10 in free space to define a motion pattern for the juvenile product having up to three dimensions (and up to six degrees of freedom). For example, the mobile device user could rock or sway the mobile device 10 similarly to the way that the mobile device user rocks or sways the juvenile when holding the juvenile. That way, the mobile device user's own rocking or swaying pattern can be detected by the mobile device/app and uploaded to the juvenile product 12 for replication by the juvenile product 12. At step 124, between activating the start and stop buttons at steps 122 and 126, the movement of the mobile device 10 in up to three dimensions (and up to six degrees of freedom) can be detected and captured at step 124 by the mobile device's accelerometer and gyroscope systems 34, 36. The captured motion pattern can then be displayed on the user interface 40, such as with a lighting pattern, so that the mobile device user can accept or reject it at steps 128 to 132. In various embodiments, the motion displayed on the user interface 40 can be in two dimensions (X and Y), with the vertical dimension (Z) eliminated for purposes of the replication. In other embodiments, the intensities of the lights and/or different colors can be used to indicate changes in the vertical position.
Another input mode at step 120 is that the user could select to input a sound (audio recording), whose waveform is translated to a vibration pattern for the juvenile product 10. In such an input mode, at step 124, between activating the start and stop buttons at steps 122 and 126, the mobile device user could sing a song, hum a tune, play an instrument, or play a music recording, for example. The mobile device's microphone can pick up the sound and the processor 60 (executing the app 50) can convert the waveform for the captured audio to a vibration pattern for the juvenile product 12. For example, high amplitude portions of the waveform can correspond to high intensity vibrations, and vice versa, and long amplitude portions of the waveform can correspond to long vibrations, and vice versa. Also, the vibration timing can correspond to or be proportional to the amplitude spacing in the waveform (e.g., the timing between successive vibrations can correspond to the timing between successive high amplitude portions of the wave). The processor 60 can replicate the vibration pattern through its vibrators 47 and/or lights so that the mobile device user can accept or reject the corresponding vibration pattern at steps 128 to 132. The mobile device 10 could also play the captured sound recording through its speakers 45 in concert with the displayed vibration pattern. The captured sound can also be uploaded in a file to the juvenile product 12 for playing by speakers of the juvenile product 12 in concert with the corresponding vibration pattern.
Another way that the mobile device user could define a new stimulation pattern for the juvenile product is to use an audio file stored on the mobile device 10 (or a portion of the audio file), with the waveform for the audio file being converted to a vibration pattern for the juvenile product 12, as described above. For example, the user interface 40 of the mobile app 50 may allow the mobile device user to select an option to create a vibration pattern for the juvenile product 12 using a new audio recording or to use an audio file already stored on the mobile device 10. A new audio recording can be translated to a vibration pattern as described in the prior paragraph. If the user selects to use an already-stored audio file, the mobile app 50 may link to the audio files on the mobile device 10 and display a listing of the stored audio files. When the user selects one of the stored audio files, the mobile app 50 (through its user interface) can ask the mobile device user if it wants to user the entire audio file or just a portion of it. If the mobile device user selects to use a portion of the audio file, the mobile app 50 can play the audio file, and simultaneously provide input buttons or controls where the user could indicate the start and stop times of the portion of the audio file to be used for the vibration pattern. The waveform of the audio file (whether the entirety of it or just a portion) can be translated to a vibration pattern for the juvenile product as described above. As before, the audio file can also be uploaded to the juvenile product 12 for playing by speakers of the juvenile product 12 in concert with the corresponding vibration pattern.
In yet another embodiment, the mobile device's camera could recognize a motion pattern defined by the user. For example, the camera 38 could include video recording capabilities, and the camera 38 could record a motion pattern drawn by the user on a suitable surface. The mobile device's processor 60 can then translate the captured motion pattern drawn by the user to motion vectors that are representative of the user's drawn pattern. The mobile device's processor 60 and/or the juvenile product's processor 20 can then translate the motion vectors to control signals for the actuator(s) 28 to implement the user-defined pattern.
Once the stimulation pattern is defined by the mobile device user and captured by the mobile/device app, the mobile device user can assign a name or other type of ID to it (e.g., “Pattern A”) so that the user can select it later. A number of different patterns can be defined in this manner and each assigned a different name for later recall and execution by the juvenile product 12.
Returning to the left side of
In generating the commands for the actuator(s) 28 for the user-defined stimulation pattern, the processor 60 needs data about the actuator(s) 28 of the juvenile product 12 so that it can appropriately scale the user-defined stimulation pattern to the motion range for the juvenile product 12. The data about the actuator(s) 28 of the juvenile product 12 could be downloaded to the mobile device/app from the remote server 14 at the registration step (step 102 of
At step 110, when a user of the juvenile product 12 inputs a command to the juvenile product 12 to execute a particular previously-defined user-defined pattern (Pattern A), the processor 20 of the juvenile product 12 can process data corresponding to the commands stored in the memory 22 and, based on that processing, send control signals to the controller(s) 26 to correspondingly control the actuator(s) 28 of the juvenile product 12 to replicate the user-defined stimulation pattern.
In another embodiment, the remote server 14 may translate the captured stimulation pattern to the actuator command signals for the juvenile product 12 at step 106. Such an embodiment requires a suitable data connection between the mobile device 10 and the remote server 14. The mobile device 10 can transmit data representing the captured stimulation pattern to the remote server 14 via the network 16. The remote server can then process the captured stimulation pattern data to develop the corresponding actuator command signals for the juvenile product 12. Then the server 14 can transmit data for the actuator command signals to the mobile device 10 or the juvenile product 12 via the network 16. If the data for the actuator command signals are transmitted to the mobile device 10, then the mobile device can upload them to the juvenile product at step 108.
In another embodiment, the processor 20 of the juvenile product 12 translates the captured pattern to the corresponding actuator command signals for the juvenile product 12. In such an embodiment, the juvenile product 12 receives the data representing the captured stimulation pattern either directly from the mobile device 10 or indirectly via the remote server 14. The memory 22 of the juvenile product 12 can already store the data about the actuator(s) 28 and/or it can download them from the remote server 14.
Once the actuator command signals are uploaded to the juvenile product 12 at step 108, the juvenile product 12 can be controlled to execute the user-defined stimulation patterns as described above. In various embodiments, the user could select the desired user-defined pattern from the mobile device 10, in which case the selection is transmitted to the juvenile product 12 for execution. In other embodiments, the user could select the desired user-defined pattern from the user interface 24 of the juvenile product 12. As mentioned above, the mobile device user could define numerous stimulation patterns in this manner, with each uploaded to the juvenile product 12 and stored in the memory 22, for later selection by the user via the mobile app or the user interface 24 of the juvenile product 12. Each user-defined pattern could be associated with a unique name or ID to facilitate selection of the desired user-defined pattern. For example, when the user selects to execute a user-defined pattern, the mobile app 50 or the user interface 24, as the case may be, may show the stored user-defined stimulation patterns in a listing or menu, and the user can select the desired one.
In the description above, the mobile device 10 was described as being in wireless communication with the juvenile product 12. It should be noted, however, that in various embodiments, the mobile device 10 and juvenile product 12 could have a wired data connection. For example, each of the mobile device 10 and juvenile product 12 could have a USB-type port that allows a USB cable to be connected therebetween. Any of the wireless data communications between the mobile device 10 and juvenile product 12 described above could be performed with such a wired connection according to various embodiments of the present invention.
In another possible use mode for the mobile app 50 and juvenile product 12, instead of defining a new stimulation pattern for the juvenile product 12 as described above in connection with

Horizontal reciprocating assembly 361 includes a rigid platform 365. Rigid platform 365 is generally I-shaped having top and bottom sides 367 and 369, respectively, and left and right sides 371 and 373, respectively. Top side 367 of rigid platform 365 includes at least one grooved wheel 375, and preferably two grooved wheels 375, similar in function and appearance to a pulley wheel, suitably disposed thereon such that top side 367 of rigid platform 365 is rollingly supported by grooved wheels 375. A rail 377 is fixably attached to bottom support housing 350 of base 303. Rail 377 rollingly receives grooved wheels 375 on top side 367 of rigid platform 365. Bottom side 369 of rigid platform 3365 includes at least one wheel 376, and preferably two wheels 376, suitably disposed thereon such that bottom side 369 of rigid platform 365 is rollingly supported by wheels 376. A slot 378 is provided to rollingly receive wheels 376 on bottom side 369 of rigid platform 365. Top side 367 is provided with grooved wheels 375 positioned on a rail 377 while bottom side 369 is provided with wheels 376 positioned within a slot 378 to account for any manufacturing error in rigid platform 365. If rigid platform 365 is too long or short, wheels 376 will “float” a slight amount within slot 378 to account for this manufacturing error. Thus, in a preferred embodiment, horizontal reciprocating assembly 361 is capable of rolling back and forth along rail 377 and slot 378, thereby allowing a horizontal displacement of the horizontal reciprocating assembly 361 of approximately three inches.
Horizontal reciprocating assembly 361 further includes a first motor 379 having a drive shaft 381 mounted to bottom support housing 350 and a slide crank assembly, denoted generally as reference numeral 383, also mounted to bottom support housing 350. Slide crank assembly 383 includes a gearing assembly having a set of first gears 385 operationally coupled to drive shaft 381 of first motor 379 and a large second gear 387 operationally coupled to first gears 385. Slide crank assembly 383 further includes a crank member 389 having a first end 391 and a second end 393. First end 391 of crank member 389 is rotationally coupled to a point on the outer circumference of second gear 387, and second end 393 of crank member 389 is fixedly coupled to a point approximately in the center of left side 371 of rigid platform 365. In operation, actuation of first motor 379 causes rotation of first gears 385 which in turn causes rotation of second gear 387. The rotation of second gear 387 causes crank member 389 to either push or pull rigid platform 365 depending on the position of crank member 389. This operation effects a reciprocating horizontal movement of rigid platform 365, along with everything mounted thereon, back and forth along rails 377. Accordingly, this system allows a single motor (i.e., first motor 379) to move rigid platform 365 back and forth with the motor only running in a single direction, thereby eliminating backlash in the system. The system for controlling horizontal reciprocating assembly 361 to achieve the desired motion profile will be discussed in greater detail hereinafter.

First double scissor mechanism 395 includes a first pair of spaced-apart parallel members 401, 401′ and a second pair of spaced-apart parallel members 403, 403′. Second double scissor mechanism 397 includes a third pair of spaced-apart parallel members 405, 405′ and a fourth pair of spaced-apart parallel members 407, 407′.
Lower ends 401L of the first pair of spaced-apart parallel members 401, 401′ and lower ends 407L of the fourth pair of spaced-apart parallel members 407, 407′ are rotatably pinned to each other and to rigid platform 365. Likewise, upper ends 403U, 403U′ of second pair of spaced-apart parallel members 403, 403′, and upper ends 405U, 405U′ of third pair of spaced-apart parallel members 405, 405′ are rotatably pinned to each other and to the supporting platform 399.
First and second horizontal bars 409, 411 are provided and extend transversely between lower ends of second pair of spaced-apart parallel members 403, 403′, and between lower ends of third pair of spaced-apart parallel members 405, 405′, respectively, for additional structural stability. In addition, first and second horizontal bars 409, 411 may further include bearing wheels 413 at their ends for supporting vertical reciprocating assembly 363 and supporting platform 399 and allowing smooth translational movement of first and second horizontal bars 409, 411 during operation.
Still further, third and fourth horizontal bars 415, 417 extend transversely between the upper ends 401U, 401U′ of the first pair of spaced-apart parallel members 401, 401′ and the upper ends 407U, 407U′ of the fourth pair of spaced-apart parallel members 407, 407′, respectively. Third and fourth horizontal bars 415, 417 include bearing wheels 419 at their ends for supporting support platform 399.
First pair of spaced-apart parallel members 401, 401′ is pivotally secured at a central portion thereof to second pair of spaced-apart parallel members 403, 403′ via horizontal pivot pins, or the like. Correspondingly, third pair of spaced-apart parallel members 405, 405′ is also pivotally secured at their respective central portions to fourth pair of spaced-apart parallel members 407, 407′ via horizontal pivot pins, or the like.
As a consequence of the foregoing description of the double scissor mechanism, when supporting platform 399, which is designed to support seating portion 309, is displaced in a vertically upward direction, both front and rear supporting and non-supporting members move in crossed fashion relative to the pivot pins such that the double scissor mechanism extends between rigid platform 365 and the upwardly displaced supporting platform 399 as illustrated by the successively increased supporting platform 399 height in
Additionally, vertical reciprocating assembly 363 may be provided with at least one, and preferably two, resistive mechanical elements 423, such as a tension spring, fixably attached between lower ends 403L of second pair of spaced-apart parallel members 403, 403′ and the lower ends 405L of third pair of spaced-apart parallel members 405, 405′ whereby the upward vertical motion of vertical reciprocating assembly 363 is assisted by resistive mechanical element 423 because it pulls the relevant portions of the double scissor mechanism toward each other. The position of restrictive mechanical element 423 described above is not to be construed as limiting as the exact location of the attachment of resistive mechanical element 423 to the double scissor mechanism can be varied with similar results so long as it is attached to portions that get closer together as supporting platform 399 rises away from base 303 and it is attached in a way that assists that movement. Resistive mechanical element 423 also has the benefit of counteracting the effects of gravity because it acts to reduce downward movement when properly placed.
In yet another aspect, the resistive mechanical element 423 comprises a compression spring (not shown) placed in an advantageous position relative to vertical reciprocating assembly 363, such as between rigid platform 365 and supporting platform 399 in order to assist vertical expansion of the double scissor mechanism and resist vertical contraction of the double scissor mechanism.

The control system desirably includes a variety of input sensors. For example, the control system may include a horizontal encoder 443 coupled to a back shaft 445 of first motor 379. Horizontal encoder 443 may include an infrared (IR) sensor 447 and a disk 449 with single hole or slot 451 positioned thereon (see
In one general aspect, therefore, the present invention is directed to a method of defining a stimulation pattern for a juvenile product 12. The method comprises the step of recognizing, by one or more sensor systems of the mobile device 10 that has a mobile application 50 that is linked to the juvenile product 12, a user-defined stimulation pattern for the juvenile product 12. The method further comprises the step of determining, by one or more processors, control signals for one or more actuators 28 of the juvenile product 12 based on the recognized, user-defined stimulation pattern. The one or more actuators 28 are for imparting movement on a juvenile-supporting structure of the juvenile product 12 and the control signals are ultimately stored in a memory 22 of the juvenile product 12. The method further comprises the step of, in response to receiving a command to execute the user-defined stimulation pattern, controlling, by the juvenile product 12, the one or more actuators 28 of the juvenile product 12 based on the stored control signals for the one or more actuators 28 for the user-defined stimulation pattern. For example, the processor 20 of the juvenile product 12 can process the control signals stored in the memory 22 and, based thereon, issue command signals to the controller(s) 26 that control the operation of the actuator(s) 28, to thereby controlling the movement of the juvenile-supporting structure of the juvenile product.
In various implementations, determining the control signal(s) comprises translating the recognized user-defined stimulation pattern to the control signal(s) for the one or more actuators of the juvenile product. In other implementations, determining the control signal(s) comprises matching the recognized user-defined stimulation pattern to a pre-defined stimulation pattern of the juvenile product.
The one or more sensor systems of the mobile device that recognize the user-defined stimulation pattern may comprise one or more accelerometers 34 of the mobile device, in combination with one or more gyroscopes 36, a pressure-sensitive touchscreen 40 of the mobile device, a microphone 39, and/or a camera 38 of the mobile device.
The control signal(s) for the one or more actuators 28 of the juvenile product 12 may be determined by one or more of the processors 60 of the mobile device 10, and the determined control signal(s) can be uploaded from the mobile device 10 to the juvenile product 12. Alternatively, the control signal(s) for the one or more actuators 28 of the juvenile product 12 may be determined by a remote server 14 that is in communication with the mobile device 10 via a computer data network 16. In such an embodiment, the control signal(s) can be uploaded from the remote server 14 to the juvenile product 12, directly or via the mobile device 10. In yet other embodiments, one or more processors 20 of the juvenile product can determine by the control signal(s) based on the user-defined stimulation pattern that is recognized by the mobile device 10 and transmitted to the juvenile product.
In yet another general aspect, the present invention is directed to a system of defining a stimulation pattern for a juvenile product. The system comprises means 34, 36, 40, 39 of the mobile device for recognizing a user-defined stimulation pattern for the juvenile product 12; means 20, 60, 14 for determining control signals for one or more actuators 28 of the juvenile product 12 based on the recognized, user-defined stimulation pattern; and means 20, 22, 26 for controlling, in response to receiving a command to execute the user-defined stimulation pattern, the one or more actuators 28 of the juvenile product 12 based on the control signals for the one or more actuators 28 for the user-defined stimulation pattern.
In yet another general aspect, the present invention is directed to a system that comprises a juvenile product 12 and a mobile device 10 that is in communication with the juvenile product 12. The juvenile product 12 comprises a juvenile-supporting structure, at least one actuator 28 for imparting motion on the juvenile-supporting structure, and one or more juvenile product processors 20. The mobile device comprises one or more sensor systems 34, 36, 40, 49, one or more mobile device processors 60; and a mobile application 50 that is executed by the one or more processors 60, where the mobile application 50 is linked to the mobile device 12. The one or more sensor systems of the mobile device are configured to recognize a user-defined stimulation pattern for the juvenile product. Either the one or more juvenile product processors and/or the one or more mobile device processors are configured to determine control signals for the at least one actuator 28 of the juvenile product 12 based on the recognized, user-defined stimulation pattern. The control signals are stored in a memory 22 of the juvenile product 12 for later execution by the juvenile product 12 in response to the juvenile product 12 receiving a command to execute the user-defined stimulation pattern.
In yet another general aspect, the present invention is directed to a juvenile product that comprises a juvenile-supporting structure and at least one actuator for imparting motion on the juvenile-supporting structure. The juvenile product also comprises a communication circuit for receiving a user-defined stimulation pattern for the juvenile product from an external, mobile device, and a control circuit connected to the communication circuit, wherein the control circuit is for controlling the at least one actuator according to the received user-defined stimulation pattern.
