Abstract

Systems for soothing and prolonging sleep maintain an experience of riding in a vehicle in a car seat, even as a pattern of driving changes, when vehicle motion ceases or when the car seat is removed from the vehicle. Sensors detect one or more of motion, light and sound in an environment of the car seat. As motion, light and/or associated with the ride decrease, change or stop, a controller automatically controls actuators to apply compensatory motion, light and/or sound in the environment of the car seat, in order to provide continuity of the riding experience and decrease likelihood of an infant awakening or fussing. This allows the driver of the vehicle to concentrate on driving safely, rather than breaking concentration on the road in order to soothe the infant.

Claims

1. A system for soothing or prolonging sleep of a child in an environment of a car seat, comprising:

at least one actuator configured with the car seat or a base of the car seat for imparting one or more of movement, sound and light to the environment;

at least one sensor for sensing at least one condition of the environment;

a controller for controlling the at least one actuator to induce one or more of motion, sound, and light to the environment based upon the at least one sensed condition such that a level of the sensed condition remains substantially constant.

2. The system of claim 1, wherein the controller operates to increase output of one or more of movement, sound, and light from the at least one actuator to the environment when a level of at least one sensed condition reduces below a predefined threshold.

3. The system of claim 1, the controller, the sensor, and the actuator sharing a common housing.

4. The system of claim 1, the housing being attachable to the car seat or to the base of the car seat.

5. The system of claim 1, the system being configured with the car seat or the base.

6. The system of claim 1, wherein the controller and the actuator are contained within a common housing and the sensor is remote from the housing and in communication with the controller.

7. The system of claim 1, wherein the sensor comprises a microphone and the actuator comprises a speaker, wherein the controller receives signals from the microphone and determines an ambient noise level within the environment, compares ambient noise level to a predefined threshold, and activates the speaker to generate sound within the environment when the ambient noise level is below the threshold.

8. The system of claim 7, the generated sound comprising one or more of white noise, engine noise, traffic noise, conversation, music and pre-recorded customized noise.

9. The system of claim 7, wherein the microphone and speaker share a housing with the actuator and the controller.

10. The system of claim 7, wherein the microphone, the speaker, the actuator, the controller and the sensor are configured with the car seat or the base.

11. The system of claim 7, the controller selected from the group comprising a smart phone, an MP3 player, an iPod, a tablet, an iPod nano, an iPod mini, and a microcontroller.

12. The system of claim 7, further comprising an interface for one or more of a memory stick, a memory card, a smart phone, an iPad, a tablet computer and a personal device.

13. The system of claim 12, the controller storing a recording of the ambient noise in memory.

14. The system of claim 13, the controller determining a match to the recording to identify at least one sound within the environment.

15. The system of claim 14, the controller selecting an item within a playlist based upon the identified sound and playing the item through the speaker.

16. The system of claim 15, the item comprising one or more of white noise, engine noise, traffic noise, calm conversation, intermittent conversation, argumentative conversation, news broadcasts, talk radio, and music.

17. The system of claim 14, the controller controlling the speaker to generate sound similar to the identified sound when a level of the sensed sound falls below the threshold.

18. The system of claim 17, the controller increasing volume of the generated sound in proportion to the ambient noise level with respect to the threshold.

19. The system of claim 14, the controller comprising software that matches the identified sound with an item stored in a playlist on a personal device, wherein the controller plays the item through the speaker.

20. The system of claim 19, wherein the software synchs the item with the detected sound when playing the item.

21. The system of claim 14, wherein the controller determines that the infant is crying or fussing when the identified sound matches the sound of a child crying and/or fussing.

22. The system of claim 21, wherein the controller replays an item from a playlist when the controller determines that the infant is crying or fussing.

23. The system of claim 21, wherein the controller modifies the stimulus to the environment when the controller determines that the infant is crying or fussing.

24. The system of claim 1, wherein the at least one actuator comprises a light source that is configured with the car seat to impart light into the environment.

25. The system of claim 24, the light source being configured with a cover/shade of the car seat.

26. The system of claim 25, wherein the at least one sensor comprises an optical sensor for sensing one or both of an ambient light level and an ambient light characteristic within the environment, and wherein the controller controls the light source to generate light within the environment based upon the sensed ambient light level or characteristic, the characteristic selected from a hue of light, a flicker frequency, a brightening or dimming period and a time period between light events.

27. The system of claim 26, wherein the light source comprises a fiber optic display woven or otherwise built into the cover/shade.

28. The system of claim 27, wherein the controller controls the fiber optic display to emulate, in varying colors, one or more of:

twinkling stars, a pattern, a shape, and a picture.

29. The system of claim 28, wherein the controller controls the fiber optic display to emulate, in varying colors, one or more of:

twinkling stars, a pattern, a shape, and a picture, upon detecting that the child is fussing or crying.

30. A sleep and wake system for public transport, comprising:

at least one actuator configured with a seat of a public transportation vehicle, for imparting one or more of movement, sound and light to an environment of the seat;

a sensor for sensing a condition of the environment of the seat;

a microprocessor for comparing the sensed condition with a threshold level for the sensed condition; and

a controller for controlling the at least one actuator to add one or more of motion, sound, and light to the environment based upon the at least one sensed condition, when the sensed condition approaches or falls below the threshold level, such that a level or characteristic of the sensed condition remains relatively constant despite an ambient decrease in the sensed condition.

31. The system of claim 30, further comprising a user interface for selecting one or more of a desired stop, a desired wake-up time and a desired waking period;

wherein the actuator alters output of the movement, sound or light to wake a sleeping passenger at or prior to the desired stop or wake up time, and/or according to the desired waking period.
