The disclosed embodiment relates generally to an infant care apparatus and, more particularly, to an infant care apparatus having an occupant area that is movable by a drive mechanism.
Baby swings, bouncy seats, cradles, and bassinets have been used to hold, comfort, and entertain infants and babies for many years. Prior art bouncy seats are normally constructed with a wire frame that contains some resistance to deformation that is less than or equal to the weight of the child in the seat. Thus, when the child is placed in the seat, his or her weight causes a slight and temporary deformation in the wire structure that is then counteracted by the wire frame's resistance to deformation. The end result is that the child moves up and down slightly relative to the floor. This motion can be imparted to the seat by a caregiver for the purpose of entertaining or soothing the child.
Baby swings normally function in much the same way as swing sets for older children; however, the baby swing usually has an automated power-assist mechanism that gives the swing a “push” to continue the swinging motion in much the same way a parent will push an older child on a swing set to keep them swinging at a certain height from the ground.
There are some products that have recently entered the market that defy easy inclusion into either the bouncy or swing category. One such product includes a motorized motion that can move the infant laterally, but only has a single degree of motorized freedom and is thus limited in the motion profiles that can be generated. While the seat can be rotated so that the baby is moved back and forth in a different orientation, there remains only one possible motion profile.
As a baby or infant occupies the baby swing, bouncy seat, cradle, and bassinet, the mood of the baby or infant may change (e.g., from a calm mood to crying, etc.). In other aspects, a state of the babies or infants may change (e.g., from sleeping to awake or vice versa, etc.). Generally, changes in the baby's or infant's mood or state are monitored directly by a caretaker or through a baby monitoring device which typically includes a camera and microphone that merely transmits a video and audio of the baby or infant to a remotely located monitoring device accessible to the caretaker. As the baby's mood or state changes the caretaker must physically tend to the baby or infant so as to sooth the baby or infant.
A need exists for a motorized infant support that is capable of simultaneous or independent movement in at least two directions, and can reproduce a large number of motion profiles with those two directions. A need also exists for a reactive infant support that is capable of adjusting action/motion characteristics of the infant support based on the baby's or infant's mood or state.
For purposes of the description hereinafter, the terms “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, “lateral”, “longitudinal”, and derivatives thereof shall relate to the aspects of the disclosed embodiment as it is oriented in the drawing figures. However, it is to be understood that the aspects of the disclosed embodiment may assume alternative variations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary of the aspects of the disclosed embodiment. Hence, specific dimensions and other physical characteristics related to the aspects of the disclosed embodiment are not to be considered as limiting.

With the at least one toggle mechanism 250 (and thus the movable support 210) in the raised position 1150, the automatically actuable grip members 220, 225 are in and remain in the open position 230 through interaction between the camming mechanism 212 and the cam follower surfaces 222, 227 of the automatically actuable grip members 220, 225. With the automatically actuable grip members 220, 225 in the open position 230, the mating support member 8 of the infant support 2 is free to be removed or placed within the support seat 211 of the movable support 210 so as to mount the infant support 2 to the base 3. In order to bias the automatically actuable grip members 220, 225 in the open position 230, the cam follow surfaces 222, 227 of the automatically actuable grip members 220, 225 are configured to interface with the camming surfaces 213 of the camming mechanism 212. For example, without the infant support 2 present on the support seat 211, the movable support 210 is in the first raised position 1150 such that the camming surfaces 213 of the camming mechanism 212 are engaged with and biasing the cam follower surfaces 222, 227 of the automatically actuable grip members 220, 225 in direction T5 and direction T6, respectively, to the open position 230 against the biasing force of torsion springs 260. As the mating support member 8 of the infant support 2 is placed on the movable support 210 by a user and the movable support 210 is moved in direction D4 into the second lowered position 1160, the camming surfaces 213 of the camming mechanism 212 are disengaged from the cam follow surfaces 222, 227 (i.e., lowered such that the cam follow surfaces 222, 227 of the automatically actuable grip members 220, 225 follow or slide along the camming surfaces 213 of the camming mechanism 212 in respective direction D6 and direction D7). The torsion springs 260 of the respective automatically actuable grip members 220, 225 effects rotation of the respective automatically actuable grip members 220, 225 in respective direction T1 and direction T2. The respective torsion springs 260 biases the automatically actuable grip member 220 in direction T1 and the automatically actuable grip member 225 in direction T2 about respective pivot axes 221, 226 to place the automatically actuable grip members 220, 225 in the closed position 240.

The automatically actuable grip members 220′, 225′ each include a base 231′, 235′ with an aperture 232′, 236′, through which a respective pin 299′ extends, and cam followers 222′, 227′ extending from the base 231′, 235′. Clamp arms 233′, 237′ extend from the base 231′, 235′ and include gripping surfaces 234′, 238′. The automatically actuable grip members 220′, 225′ are coupled to the respective pins 299′ so as to rotate relative to the housing cover 280C (and the base 3) between the open position 230 and the closed position 240. Here, the camming surfaces 284 of the camming mechanism 283 are engaged with and biasing the cam followers 222′, 227′ of the automatically actuable grip members 220′, 225′ in the open position 230 when the housing cover 280C is lowered in direction D4. As the mating support member 8 of the infant support 2 is placed on the movable support 210 by a user and the movable support 210 is lowered in direction D4 into the second position, the camming surfaces 284 of the camming mechanism 283 are lowered in direction D4 such that the cam followers 222′, 227′ of the automatically actuable grip members 220′, 225′ are rotated in respective directions T5 and direction T6 which forces the automatically actuable grip members 220′, 225′ into the open position 230. A torsion spring integrated into the automatically actuable grip members 220′, 225′ effects rotation of the automatically actuable grip members 220′, 225′ in respective direction T3 and direction T4 on the automatically actuable grip members 220′, 225′ to force them into the closed position 240 when the camming mechanism 283 is disengaged (i.e., the housing cover 280C is toggled into the raised position). The infant support coupling 200′ may further include shock towers 288 to absorb any impacts and retain stability of the infant support coupling 200′.

In one aspect, the movable stage 10 may be provided with at least one resilient element 98, such as a tension spring, fixably attached between two or more of the pair of spaced-apart parallel members 101, 101′ 103, 103′ 105, 105′ 107, 107′. The resistive mechanical element(s) 98 may be provided and configured so as to assist a lifting motion assembly 65 (described below) in extending or retracting the double scissor mechanism 94 in the second direction D2. For example, the resistive mechanical element(s) 98 may be coupled to the lower end 103L, 103L′ of second pair of spaced-apart parallel members 103, 103′ and the lower end 105L, 105L′ of the third pair of spaced-apart parallel members 105, 105′ (

The lateral motion assembly 61 includes a driving portion with a first motor 62 having a drive shaft 63 and being dependent from the base 3, and a slide crank assembly 80 mounted to the bottom support housing 4 of the base 3. The first motor 62 is configured to impart the first cyclic motion in the first direction D1 to the movable stage 10. The slide crank assembly 80 includes a gearing assembly 86 having a set of first gears 81 operatively coupled to the drive shaft 63 of the first motor 62 and a second gear 82 operatively coupled to the set of first gears 81. A crank member 83, having a first end 84 and a second end 85, couples the second gear 82 to the first platform 70 to impart the first cyclic motion provided by the first motor 62 on the first platform 70 of the movable stage 10. For example, the first end 84 of the crank member 83 may be rotationally coupled to a point on the outer circumference of the second gear 82, and the second end 85 of the crank member 83 may be rotationally coupled to the first platform 70.
In operation, actuation of the first motor 62 causes rotation of the first gears 81 which in turn causes rotation of the second gear 82. The rotation of the second gear 82 drives the crank member 83 coupled to the outer circumference of the second gear 82. As the first end 84 of the crank member 83 rotates about the second gear 82, the first platform 70 is pushed and pulled by the second end 85 of the crank member 83 in the first direction Dl. This operation effects reciprocation of the driven portion of the motion assembly 61 joined to and thus imparting lateral motion to the movable stage 10 in the first direction along, e.g., the rails 78. Accordingly, the lateral motion assembly 61 is configured such that a single motor (i.e., the first motor 62) moves the first platform 70 in the first direction (e.g., horizontally) with the first motor 62 only running in a single direction, thereby eliminating backlash in the system. The system for controlling the lateral motion assembly 61 to achieve the desired motion profile will be discussed in greater detail hereinafter.

Since the lateral motion assembly 61 and the lifting motion assembly 65 each respectively include the first motor 62 and the second motor 66, separate and distinct from one another, the lateral motion assembly 61 can be controlled independently of the lifting motion assembly 65. Independently controlling the first motor 62 and the second motor 66 allows for a variety of variable motion profiles to be selected that include cyclic motion in the first direction, the second direction, or both.

As noted above, the controller 51 is communicably coupled to the drive mechanism 60 and the vibratory mechanism 90. The controller 51 is configured so as to effect movement of the infant support 2 in the selectably variable motion profiles with selectable vibration modes selected, with the controller, from different selectably variable motion profiles and selectably different vibration modes for each of the different selectable variable motion profiles.
The control system 50 may further include a control panel 52 for viewing and controlling speed and motion of the drive mechanism 60, one or more control switches or knobs 54 for causing actuation of the drive mechanism 60, and a variety of inputs and outputs operatively coupled to the controller 51. For example, the control system 50 may include a horizontal encoder 130 (
In addition, while the horizontal encoder 130 and the vertical encoder 135 were described hereinabove, this is not to be construed as limiting as magnetic encoders, as other types of encoders well known in the art may also be used. It may also be desirable to provide an arrangement in which two or more control switches associated with respective motors are required to both be actuated to effect speed control in the desired direction. Furthermore, while it was described that the horizontal encoder 130 and the vertical encoder 135 only include a single slot, this is not to be construed as limiting as encoders with a plurality of slots may be utilized.
In one aspect, the control system 50 may further include horizontal and vertical limit switches 165, 167 (
The control panel 52 may also have display 53 to provide information to the user, such as, for example, motion profiles, volume of music being played through speakers 56, and speed of the reciprocation motion, etc. In one aspect, the control panel 52 may be a touch screen control panel, a capacitive control panel, or any suitable user interface configured to receive the common selection input from a user for selecting the different selectably variable motion profiles. Control switches 54 (which may be capacitive switches, areas of a touch screen, toggle switches, buttons, etc.) may include user input switches such as a main power switch, a start/stop switch, a motion increment switch, a motion decrement switch, a speed increment switch, a speed decrement switch, and the like. In one or more aspects, at least a portion of the control panel 52 functionality described herein is provided on the mobile device 360 so that the infant care apparatus 1 can be remotely controlled and/or remotely monitored through the mobile device 360. The controller 51 of the control system 50 may also include a variety of outputs. These outputs include, but are not limited to a Pulse Width Modulation (PWM) for the first motor 62, a PWM for the second motor 66, a display backlight.
The following explanation provides an understanding of an exemplary control system 50 of the infant care apparatus 1. Based on the physical limitations of the first motor 62 and the second motor 66 of the lateral motion assembly 61 and the lifting motion assembly 65, the maximum speed of the first motor 62 may be about a four second period and the maximum speed of the second motor 66 may be about a two second period. Based on these constraints, the following relationships may be established:
The speed of the first motor 62 is independently set to a period and a feedback control loop is used to ensure that the first motor 62 remains at a constant speed despite the dynamics of the components of the infant care apparatus 1. As mentioned above, the output of the control system 50 is a PWM signal for the first motor 62. One possible input for the control system is velocity of the first motor 62, which can be observed from the speed of the first motor 62 as observed by the horizontal encoder 130. However, in order to avoid computationally expensive calculations, it is possible to operate in the frequency domain and use the number of processor ticks between ticks of the horizontal encoder 130 as the input variable. This allows the calculations of the controller 51 to be limited to integers rather than manipulating floats. The vibratory mechanism 90 generates vibrations in different modes which are superposed over each variable selectable motion profile controlled as noted.
The physical drive mechanism of the lateral motion assembly 61 is the slide crank assembly 80 which is configured so that the first motor 62 reciprocates the first platform 70 back and forth without the need to change directions. Since the first motor 62 is only required to run in one direction, the effect of backlash is eliminated in the system, thereby removing problems with the horizontal encoder 130 on the back shaft 131 of the first motor 62.
It is known that the natural soothing motions a person uses to calm a baby are a combination of at least two motions that each move in a reciprocating motion that has a smooth acceleration and deceleration such that the extremes of the motion slow to a stop before reversing the motion and are fastest in the middle of the motion. This motion is the same as that generated from a sinusoidal motion generated from the combination of the slide crank assembly 80 and the worm gear drive assembly 120. The slide crank assembly 80 and the worm gear drive assembly 120 are configured so that the driving motors run at a constant rotational speed while the output motion provided to the infant seat 7 slows and speeds up, mimicking the motion of a person soothing a child. These assemblies also configured such that the driving motors run in one direction.

Based on the feedback from the horizontal encoder 130 and the horizontal limit switch 165, the exact position of the first platform 70 (denoted “hPos”) can be determined at any point in its range of motion. Similarly, based on feedback from the vertical encoder 135 and the vertical limit switch 167, the exact position of the support platform 99 (denoted “vPos”) can be determined at any point in its range of motion.
While the control of the first platform 70 is based entirely on velocity, the control of the support platform 99 is based upon both position and velocity. For a given horizontal position (hPos) and a given motion, which dictates the number of vertical cycles per horizontal cycles (n) and phase offset (Φ) as shown in Table 1, the desired vPos can be calculated as follows:
Desired_vPos=hPos×xv2h_ratio×n+Φ (Equation 1)
where v2h_ratio is a constant defined as the number of vertical encoder ticks per cycle divided by the number of horizontal encoder ticks per cycle. Based on the actual vertical position, the amount of error can be calculated as follows:
posErr=vPos-Desired_vPos (Equation 2)
This error term must be correctly scaled to +/−verticalEncoderTicksPerCycle/2.
As an aside, if the direction of motion in Ocean Wave 204 and Car Ride 201 is irrelevant, there are two possibilities for Desired_vPos for each value of hPos and we can base the vertical error term, posErr, on the closer of the two.
The positional error term, posErr, must then be incorporated into a velocity based feedback control loop. Logically, if the vertical axis is behind (posErr<0), velocity should be increased while if the vertical axis is ahead (posErr>0), velocity should be decreased in proportion to the error as follows:
vSP=posErr×Kvp+vBase (Equation 3)
where vBasw=hSP/n×h2v_ratio (Equation 4) and h2v_ratio is defined as the horizontal ticks per cycle/vertical ticks per cycle.
The above description is for exemplary purposes only as any suitable control scheme may be utilized. As noted previously, different modes of vibrations generated by the vibratory mechanism 90 are superposed over each variable selectable motion profile controlled as noted.
In an exemplary embodiment, the infant care apparatus is configured to reciprocate the seat with a vertical displacement of about 1.5 inches and a horizontal displacement of about 3.0 inches with a vertical displacement frequency range of between about 10 and 40 cycles per minute and a horizontal displacement frequency range of between about 10 and 40 cycles per minute. In another example, the infant care apparatus 1 is configured to reciprocate the seat with a vertical displacement more or less than about 1.5 inches and a horizontal displacement more or less than about 3.0 inches with a vertical displacement frequency range of more or less than about 10 to 40 cycles per minute and a horizontal displacement frequency range of more or less than about 10 to 40 cycles per minute.
In another aspect, at least a third reciprocation means (not shown) may be added to enable reciprocation of the seat in another direction different than the first and second directions imparted by the first and second motion assemblies 61, 65 referenced herein.

Data from the one or more peripheral device 360 is registered by the controller 51 (or by the mobile device 351 so as to effect through the controller 51) and employed to provide infant stimulation to calm and sooth the infant's mood (e.g., stop the infant from crying) or state (e.g., cause/help the infant to fall asleep and/or reduce restlessness of the infant). For example, the data from the one or more peripheral devices can be employed (as will describe herein) by the controller 51 to initiate one or more of the predetermined motions (as described herein) of the infant bed 6, initiate one or more sounds (and select a suitable sound volume), activate lights, and/or initiate vibration (as described herein) of the infant bed 6. The predetermined motions, sounds, changes in sound volume, lights, and vibrations can be activated by the controller 51 singularly or in parallel for overlapping stimulation of the infant. As noted above, the controller 51 in one or more aspects includes artificial intelligence 51A where the controller 51 is configured to vary and adjust the stimulation types and stimulation intensities provided to the infant based on the effectiveness of chosen stimulants (e.g., as determined by peripheral device feedback), so that over time the controller 51 becomes more effective at (or learns how to) sooth and entertain the needs of the infant within the infant bed 6. It is noted that while the control system 50 is described herein with respect to the infant bed 6, the infant seat 7 may be controlled in a similar manner.
As non-limiting examples of the one or more peripheral device 360, the one or more peripheral device 360 includes optical sensor(s) 361, heat-based sensor(s) 362, audio sensor(s) 363, motion sensor(s) 364, biometric sensor(s) 365, and/or any other suitable sensor(s) configured to observe (or otherwise monitor) the at least one characteristic of the infant. The optical sensor(s) 361 are any suitable optical sensors including, but not limited to, one or more of CCD and CMOS cameras. The heat-based sensor(s) 362 may be any suitable heat-based sensors including, but not limited to, any suitable pyroelectric sensors such as infrared sensors. The optical sensor 361 and heat-based sensor 362 are employed by the controller 51 (and/or mobile device 351) to monitor and measure, in conjunction with the controller 51 one or more of a change in position of the infant within the infant bed 6 (e.g., where the infant position in a series of video frames is compared to determine infant motion), infant facial expression, and/or blood oxygenation level and pulse of the infant such as through image recognition using video of the infants skin tone/color.
The audio sensor(s) 363 are any suitable sensors for detecting and/or otherwise measuring sound waves including, but not limited to, any suitable microphones. The audio sensor(s) 363 are employed by the controller 51 (and/or mobile device 351) to measure or otherwise detect changes in sound compared to nominal background noise (i.e., ambient noise of the environment in which the infant are apparatus 1 is located). The audio sensor(s) 363 are also employed by the controller 51 (and/or mobile device 351) to measure or otherwise detect types of noises from the infant within the infant bed 6, where the infant noises include, but are not limited to, crying, cooing, and babbling.
The motion sensor(s) 364 are any suitable sensors for detecting and/or otherwise measuring motion/movement of the infant within the infant bed 6. The motion sensor(s) 364 include but are not limited to one or more of cameras (e.g., to detect motion through frame comparison and image recognition), accelerometers, gyroscopes, inertial measurement units (IMUS), piezoelectric sensors, air pressure sensors, electromotive force (EMF) sensors, or any other suitable motion sensor. The motion sensor(s) 364 are employed by the controller 51 (and/or mobile device 351) to measure or otherwise detect motion of the infant within the infant bed 6 where the motion sensors are located on or worn by the infant and/or are located adjacent to (but not worn by or located on) the infant within the infant bed 6.
The biometric sensor(s) 365 are any suitable sensors for detecting and/or otherwise measuring biometrics of the infant within the infant bed 6. The biometric sensor(s) 365 include, but are not limited to, blood pressure monitors, heart rate monitors, thermometers, skin conductance sensors, pulse oximeter, motion sensors (e.g., accelerometers, gyroscopes, inertial measurement units (IMUs)) and/or any other suitable biometric sensor. In one or more aspects, the biometric sensor(s) 265 are wearable health devices 365W (
In addition to, or in lieu of, one or more of the above-noted peripheral devices 360, the infant care apparatus 1 includes position sensors 330 (such as the encoders described above) and/or current draw sensors 331. The current draw sensors 331 are communicably coupled to the drive system motors (such as at least motors 62, 66) and are configured to monitor current used by the motor(s) of the drive system. The controller 51 (or mobile device 351) is configured to determine the state (e.g., such as restlessness) of the infant within the infant bed 6 by comparing the current and positional information of the infant bed 6 (or infant seat 7) with an active infant therein with the current and position information of the infant bed 6 (or infant seat 7) with a non-active infant therein.
As noted above, data from the one or more peripheral device 360 is registered by the controller 51 (or by the mobile device 351 so as to effect through the controller 51) and employed by the controller 51 to effect a change in one or more of the action (e.g., aural stimulus (sounds, music, etc.) and visual stimulus (lights, the mobile 19, etc.)) and the motion (vibratory and motion profiles) of the infant bed 6. The change in the one or more of the action and the motion of the infant bed 6 provides infant stimulation to calm and sooth the infant's mood or state. Each of the above noted peripheral devices 360, 361-365 and sensors 330, 331 (collectively referred to herein as sensors) is configured to generate a sensor signal 399 that embodies at least one characteristic of the infant within the infant bed 6, which characteristics include those measured by the peripheral devices 360, 361-365 and sensors 330, 331. The at least one characteristic is an action characteristic (e.g., crying, cooing, babbling, and/or other aural action) and/or a motion characteristic (e.g., kicking, rolling, and/or other movements) of the infant 390. It is noted that in one or more aspects the sensors communicate directly with the controller 51, while in other aspects the sensors communicate with the controller 51 indirectly such as through a mobile device 351 (See

The state machine 51SM includes or otherwise forms a discriminator 5120 that discriminates between the different input from the peripheral devices 360, 361-365 and sensors 330, 331 and, in one or more aspects, further discriminates the intensity of such inputs so that the state machine 51SM provides an output 5106 that corresponds with the inputs and, in some aspects the intensity of the inputs. For example, the state machine discriminates the input intensity by applying one or more thresholds to one or a combination of inputs from the peripheral devices 360, 361-365 and sensors 330, 331. Examples of thresholds with which the discriminator is configured include but are not limited to, temporal thresholds, intensity thresholds, and input combination thresholds.
One example of a temporal threshold that is applied by the state machine 51SM is a duration of infant activity before the state machine 51SM provides an output that modifies one or more of the action and motion of the infant care device 1. As an example, where the infant 390 is crying and a motion of the infant car device is set to the car ride motion 201, the discriminator 5120 discriminates whether the crying has been stopped for any suitable predetermined time before the state machine provides an output 5156P that modifies or stops the motion of the infant care apparatus 1.
One example of an intensity threshold that is applied by the state machine 51SM is where thresholds are applied to a heart rate of the infant (e.g., depending on the infant's age) for adjusting one or more of the action and motion of the infant care device. For example, the discriminator 5120 discriminates the intensity of the infant's heartbeat with respect to one or more thresholds. A first or upper threshold may be indicative of a high degree of restlessness of the infant 390. A second or intermediate threshold may be indicative of a moderate degree of restlessness. A heartbeat below the second threshold may be indicative of substantially no restlessness. Where the discriminator determines the infant's 390 heartbeat is above the first threshold the state machine 51SM outputs commands to, for example, the drive system so that the infant holder moves in one of the movement patterns described herein (which movement patterns may also be determined by the discriminator) with a first speed that corresponds to the first threshold. Where the discriminator determines the infant's 390 heartbeat is above the second threshold but below the first threshold the state machine 51SM outputs commands to, for example, the drive system so that the infant holder moves in one of the movement patterns described herein (which movement patterns may also be determined by the discriminator) with a second speed that corresponds to the second threshold. Where the discriminator determines the infant's 390 heartbeat to be below the second threshold the state machine 51SM outputs commands to, for example, the drive system so that the infant holder moves in one of the movement patterns described herein (which movement patterns may also be determined by the discriminator) with a third speed. Here, the first speed is greater/faster than the second speed, and the second speed is greater/faster than the third speed. It is noted that the third speed may be zero where the infant holder is held substantially stationary.
One example of an input combination threshold is where a predetermined combination of multiple inputs trigger a change one or more of the action and the motion of the infant holder. For example, where the discriminator 5120 determines, from peripheral device/sensor data, that the infant's heart rate is increased but no other input exists (e.g., data from other peripheral devices/sensors is null or nominal) the state machine 51SM may output no change in action or motion of the infant holder. However, where the discriminator 5120 determines, from peripheral device/sensor data, that the infant's heart rate is increased and the infant is crying, the state machine 5120 outputs a change in one or more of the action and motion. For example, the output of the state machine may be to activate the drive section so that the infant holder moves in one of the predetermined motion patterns described herein. The predetermined combination of multiple inputs is adaptable, changing according to registration of changes in sensed characteristics, from a first predetermined combination to an adapted predetermined combination. For example, the controller may apply various heuristic algorithms and/or neural networks to data histories of biometric sensor data to identify corresponding characteristic combinations and/or thresholds for one or more states and revise or change the predetermined combination to an adapted predetermined combination.
While, movement of the infant holder has been described above in response to input to the state machine 51SM, such response generated by the state machine 51SM is not limited to movement of the infant holder. For example, the state machine may output command(s) that initiate one of or any suitable combination of audible sounds (e.g., music, white noise, etc.), movement of the infant holder in predetermined patterns, and vibration of the infant holder.

In one or more aspects, the controller 51 is configured to generate the indicia 353A (or cause an illumination or display of the indicia) where the indicia 353A identifies the change in one or more of the action characteristic or the infant 390 and the motion characteristic of the infant 390 sensed by the sensors (e.g., the peripheral devices 360, 361-365 and sensors 330, 331). For exemplary purposes only, where the controller 51 receives sensor signals 399 that embody a change in sensed characteristics of the infant 390, the indicia 353A presented to the user indicates that the sensed characteristic has changed. For example, the sensed characteristic may be a motion characteristic where motion characteristic changed from restless movement to substantially motionless (e.g., sleeping). Here, the controller 51 generates the indicia to indicate the motion characteristic has changed to substantially motionless. As another example, the sensed characteristic is a temperature of the infant 390, where the temperature rises from 98.6° F. (37° C.) to 100° F. (37.8° C.). Here the controller 51 generates the indicia to indicate that the temperature of the infant 390 has risen (and in some aspects the indicia includes a numerical temperature). In one or more aspects the indicia indicates both the prior state (i.e., the “from” state) and the current state (i.e., the “to” state) of the action and/or motion characteristic of the infant 390 where, for exemplary purposes only, the temperature of the infant changed from “98.6° F. (37° C.)” to “100° F. (37.8° C)”. As noted above, the indicia 353A is in one aspect a visual indicia presented on the display 53 while in other aspects the indicia is presented as an aural indicia (e.g., spoken words or other suitable audible tones or phonetics) through any suitable speakers, such as speakers 56 of the infant care device or speakers 356 of the mobile device 351. In still other aspects, the indicia 353A are presented as both aural indicia and visual indicia.
