DETAILED DESCRIPTION
(37) In an exemplary embodiment, shown in
(38) In another representative view of infant calming/sleep-aid device 10 of
(39) Reciprocating motion of main moving platform 16 about main support shaft 40 is about an axis that is orthogonal to a major plane of main moving platform 16. Reciprocating motion of main moving platform 16 is driven by actuator assembly 58.
(40) In some embodiments, the body and the head of the infant can be out of phase. For example, at relatively slow speeds, the motion of the head of the infant can be in the same direction as that of the motion of the upper body of the infant. At relatively high speeds, the reciprocal motion of the head of the infant can be in the opposite direction as that of the upper body of the infant. In another embodiment of the invention (not shown), reciprocal motion of the head of the infant can be in some other direction, such as orthogonally relative to the plane of the main support platform.
(41) Actuator assembly 58 includes drive motor 60 mounted to rigid base 32 and gear assembly 62 linked to drive motor 60 and also mounted to rigid base 32. Drive motor 60 may be an electric motor with a reciprocating drive disk and push/pull rod.
(42) Actuation of drive motor 60 causes rotation gear assembly 62 to drive eccentric drive plate 64 about an axis normal to a major plane of rigid base 32. Eccentric drive plate 64 is linked to swing arm plate 66 of actuator assembly 58 that extends from eccentric drive plate 64 to rod end 68 of screw 70 and is pivotally mounted to rod end 68 of screw 70. Screw 70 is mounted to amplitude modulation assembly 72. Amplitude modulation assembly 72 includes amplitude modulation motor 74, nut 76, mounted on nut frame 78, which swivels on rotation bearing 80 mounted to rigid base 32. The axis of rotation of nut frame 78 on rotation bearing 80 is, like that of eccentric drive plate 64, normal to a major plane of rigid base 32. Actuation of amplitude modulation assembly 72 causes movement of screw 70 along its major longitudinal axis to thereby cause rod end 68 to become more proximate or less proximate to amplitude modulation assembly 72. Arm 82 extends from an end of screw 70 opposite to rod end 68 to elastic actuator catch bracket 84, which is mounted on base 18 of main moving platform 16. Arm 82 extends through an opening defined by elastic actuator catch bracket 84 and is linked to main moving platform 16 by springs 86, 88 held in place on either side of elastic actuator catch bracket 84 by nuts 90, 92, respectively.
(43) Actuation of actuation assembly drive motor 60 causes rotation of eccentric drive plate 64 about an axis normal to a major plane of rigid base 32 which, in turn, causes reciprocal motion of swing arm plate 66 roughly along a major longitudinal axis of swing arm plate 66. Such reciprocal motion of swing arm plate 66 causes rod end 68 to move in a reciprocal motion from side-to-side of a major longitudinal axis of screw 70 which causes reciprocal rotation of nut frame 78 about an axis normal to major plane rigid base 18 and side-to-side motion of the opposite end of screw 70 opposite that of rod end 68 of screw 70. Such side-to-side movements of the opposite end of screw 70 causes reciprocal longitudinal movement of arm 82 extending through the opening defined by elastic actuator catch bracket 84.
(44) Resistance to such reciprocal motion of arm 82 causes alternating reciprocal compression and relaxation of springs 86, 88, which thereby causes reciprocal motion of main moving platform 16 about main support shaft 40 linking main moving platform 16 to rigid base 32.
(45) The amplitude of reciprocal motion of main moving platform 16 about main support shaft 40 is controlled by the location of screw 70 relative to amplitude modulation assembly 72. For example, if actuation of amplitude modulation assembly 72 causes rod end 68 to become more proximate to amplitude modulation assembly 72, the side-to-side motion of the opposite end of screw 70 will become greater, thereby causing the amplification of reciprocal motion of main moving platform 16 about main support shaft 40 to increase. Conversely, actuation of amplitude modulation assembly 72 to cause rod end 68 of screw 70 to become more remote from amplitude modulation assembly 72 will diminish the side-to-side motion of opposite end of screw 70, thereby reducing the amplitude of reciprocal motion of main moving platform 16 about main support shaft 40.
(46) Reciprocal motion of main moving platform 16 may cause a delayed reciprocal motion of moving head platform 44 about head rotation bearing 46. The reciprocal motion of moving head platform 44, although delayed, may have greater amplitude about main support shaft 40 because of the rotation of moving head platform 44 about head rotation bearing 46. However, the amplitude of reciprocal motion of moving head platform 44 about head rotation bearing 46 may be dampened by springs 56.
(47) Nevertheless, the reciprocal motion of main moving platform 16 and moving head platform 44 about main support shaft 40 is measured by motion sensing device 50 at moving head platform 44. Measurements by motion sensing device 50 are relayed back to control panel 34 and rigid base control electronics 36 which, alone, or optionally, in combination with external computer software programming, modulate actuator assembly drive motor 60 and amplitude modulation motor 74. Motion detection by motion sensing device 50 can also, optionally, modulate computer programming to affect selection and volume of sounds emitted by speakers 52. Microphones 38, in addition, or optionally, receive acoustical signals that can be fed back through rigid base control electronics 36 or/and control panel 34 to software, either on-board or remote from infant calming/sleep-aid device 10, that further modulates actuator assembly drive motor 60, amplitude modulation motor 74 and/or sounds emitted from speakers 52. Various control algorithms associated with modulation of actuator assembly drive motor 60, amplitude modulation motor 74 and speakers 52 will be more fully discussed below.
(48) In one embodiment, the device allows for a reciprocating motion at 0.5-1.5 cycles per second (cps) of ˜2″ excursions, but if the baby is fussy the device responds by delivering a smaller excursion (e.g. <1.3″) at a faster rate (˜2-4.5 cps). This fast and small motion delivers the specific degree of rapid acceleration-deceleration force to the semicircular canals in the vestibular mechanism of the inner ear that is required to activate the calming reflex.
(49) Also, the reciprocating motion typically has a maximum amplitude of less than 1.3 inches during the rapid phase of motion (˜2-4.5 cps), further ensuring safety of the infant.
(50) In one embodiment, the biometric sensor monitors the infant and generates a signal indicative of a respiration status or a cardiovascular status of the infant, such as to detect when the baby has paused breathing for a predetermined period or time, or has a cardiovascular collapse, such as indicated by a heart rate below a predetermined threshold, or the like. The sensor signal can be fed back through rigid base control electronics 36 or/and control panel 34 to a control system such as software, either on-board or remote from infant calming/sleep-aid device 10. The control system may receive and analyze the signal to determine whether a distressed status of the infant exists, and further may act, such as to generate an output to control modulation of the actuator assembly drive motor 60, amplitude modulation motor 74, or generate a telephone call to emergency services via Wi-Fi connection, and/or generate alerting and stimulating sounds that may be emitted from speakers 52. An alarm can be directed to the infant's caretakers as well.
(51) In some embodiments, in response to detection of infant distress, both vigorous motion of the platform and a loud sound can be provided. For example, providing motion of the platform at a frequency greater than 0.5 Hz and an amplitude that is greater than 1 inch, along with sound having an intensity of at least 65 dB, may provide appropriate stimulation of the infant. Of course, other amounts of stimulation are also envisioned.

(53)
(54) In another embodiment, shown in
(55) Actuation of drive motor 104 causes reciprocal longitudinal movement of push/pull rod 110 through the opening defined by elastic actuator catch bracket 112 and translates that reciprocal movement into reciprocal motion of main moving platform 16 about main rotation bearing 42, as does reciprocal motion of arm 82 through elastic actuator catch bracket 84 of the embodiment shown in
(56) As shown
(57) Motion generation module 128 receives input from speed control knob 121 and information regarding motion of the device 10, 100 from motion analysis module 132. Actuation of motion generation module 128 will modulate the actuator assemblies of the embodiments shown in
(58) Data received from accelerometer 123 is processed by motion analysis module 132 to thereby modulate the actuator assembly through motion generation module 128 and/or audio generation module 130 to thereby control the actuators assemblies or speakers, respectively. In addition, motion analysis module 132 controls status light module 134 to alert, through the status lights, whether motions of the main moving platform and the head platform are nominal or not nominal, or alternatively, through feedback, soothing or not soothing to the infant. “Nominal”, as that term is defined herein, refers to any and all motion for which the filtered acceleration signal does not exceed a specified, or predetermined maximum motion threshold for a specific length of time. The process by which the motion analysis module classifies motion as nominal or not nominal is detailed in
(59) In one embodiment, the rate of the reciprocating rotation is controlled to be within a range of between about one and about four and one-half cycles per second (cps) and with an amplitude of the reciprocating motion at a center of a head of the infant of between about 0.2 inches and about 1.3 inches. In anther embodiment, the rate of reciprocating motion is within a range of between about 0.5 and about 1.5 cycles per second and an amplitude of the reciprocating rotation at a center of the head of the infant is in a range of between about 0.25 inches and about 2.0 inches. In differing embodiments, this motion may be parallel to, or orthogonal to the platform supporting the infant's body and head.
(60) In embodiments, the control system 120 may operate in a manner wherein the intensity of maximum stimulation is increased over the course of the first weeks and subsequently weans the infant off the device's motion by incorporating the infant age as a variable used in the behavior state module 126. For example, modulation of motion and/or sound may be further controlled by at least one of the weight of the infant, the age of the infant, and the duration of the detected sounds made by the infant.

(64) Outputted data from threshold-crossing-based motion frequency estimator 148 also passes through range check 144 for indicating whether the motion is or is not soothing,
(65) Filtered accelerometer data from digital filter bank 142 also is processed to determine whether or not the acceleration exceeds a specific maximum motion threshold 150 and, depending on the result, processes that data through time-based filter 152 to provide an indication as to whether the motion is nominal or not nominal. This indication as to whether the motion is nominal or not nominal is used as input to motion generation module 128 (

User may be able to use their mobile device to instantly create and share graphic displays of their baby's sleep pattern over different periods of time, among many other uses.
(148) Devices of the type depicted in this disclosure were tested in the following way: A baby was placed in a swaddling sack (with arms in or out) attached to the mattress of the device and securely laid on his/her back. The device produced a baseline level of low pitched, rumbling noise at approximately 65 dB and baseline motion of a smooth, side-to-side rocking (2 inch excursions to either side). When the baby cried for more than ˜10 seconds, the device responded by playing a specially engineered sound that was harsher, higher pitched, more multi-frequency (75-80 dB) to mimic the intensity of the sound that the baby heard inside the mother's uterus prenatally. (This sound can be measured in situ at up to 92 dB.) If the crying continued another ˜10 seconds (despite the sound), the motion accelerated to a faster, more jiggling action of the head (2-3.5 cps, but no more than 1 inch head excursions to either side). The combination of fast movements delivered with sufficient vigor, the harsh, loud sound, and the secure sleep sack all worked together to activate the calming reflex, in the majority of irritable babies and inducing either calmness or sleep. The device responded to the baby's cry in a step-wise fashion-gradually increasing sound and then motion-to a maximal level. Once the baby was calmed the motion and sound of the device was gradually reduced in a specific, step-wise fashion back to the baseline activity.
(149) Subjects
(150) The device was tested on over twenty babies (12 girls, 10 boys) were in the device. The babies ranged from 5 weeks to 6 months of age. Their weights ranged from 8 pounds to 18 pounds.
(151) Methods and Procedures
(152) The subjects were tested to record their resting and sleeping in the device. The tests usually began when the baby was hungry and tired (immediately before their usual naptime). The time when the baby was last fed and napped was recorded and then the baby was put in the swaddling sack and placed in the device. Data from three accelerometers and a device-mounted camera was recorded to detect the vigor of activity and measure the exact excursions of the baby's head. Each test started with the device set at its lowest level for sound and motion, and the device responded to the baby's cries. The device was allowed to quickly advance through each of its stages as the cries escalated. Once the baby was calmed, the device's motion would slow, in a stepwise fashion, and the loudness and pitch of the sound would decrease, in a stepwise fashion. This format was repeated 2-4 times during sessions with each of the subjects. The first set of studies was done using a prototype with a dual motion actuator and the second set of studies was done with a prototype with a single motion actuator.
(153) Results
(154) During twenty-one tests, 19 babies were either significantly calmed or put to sleep by the device (absence of calming was due to hunger). Most calming and sleep occurred within 2 minutes of placing the baby in the device.
(155) This device is responsive to a baby's needs, such that an infant's upsets are typically soothed by vigorous stimulation to activate the calming reflex, followed by a diminution of those stimuli to help keep the calming reflex turned on and sustain the baby in a calm state and/or promote sleep (i.e. reducing sleep latency and increasing sleep efficiency.
(156) “Sleep latency” may be defined as the length of time between going to bed and falling asleep. “Sleep efficiency” may be defined as the ratio of time spent to the amount of time spent in bed.
(157) It is possible to promote infant calming and sleep through the use of swaddling plus very specific sound and motion stimuli to activate the calming reflex.
