Abstract

An electronic pillow including a pillow unit encasing at least one error microphone and at least one loudspeaker in electrical connection with a controller unit, the pillow unit also including a power source, and a reference sensing unit including at least one reference microphone in electrical connection with the controller unit, the controller unit including an algorithm for controlling interactions between the error microphone, loudspeaker, and reference microphone. A method of abating unwanted noise, by detecting an unwanted noise with a reference microphone, analyzing the unwanted noise, producing an anti-noise corresponding to the unwanted noise in a pillow, and abating the unwanted noise. Methods of hands-free communication, recording and monitoring sleep disorders, providing real-time response to emergencies, and playing audio sounds.

Claims (25)

1. An electronic pillow, comprising:

a pillow unit encasing a plurality of error microphones and a plurality of speakers;

a reference sensing unit comprising at least one reference microphone; and

a controller unit, operatively coupled to the plurality of error microphones, the plurality of speakers, and the reference sensing unit, wherein the controller unit processes signals received from the plurality of error microphones and reference sensing unit to reduce noise in an area between each of the error microphones using said speakers,

wherein the controller unit is configured to reduce noise utilizing a multiple-channel feed-forward active noise control and is further configured to processes signals received from at least one of the error microphones to perform acoustic echo cancellation.

2. The electronic pillow of claim 1 , wherein the controller unit further comprises a digital signal processing unit operatively coupled to a phone interface, wherein said acoustic echo cancellation is performed on signals received in the phone interface.

3. The electronic pillow of claim 2 , wherein the controller unit is configured to integrate the active noise control and the acoustic echo cancellation to be performed simultaneously.

4. The electronic pillow of claim 1 , wherein the error microphones are embedded in a middle third of said pillow unit.

5. The electronic pillow of claim 1 , wherein the controller unit comprises input channels equal to the number of error microphones and reference microphones, and output channels equal to the number of speakers.

6. The electronic pillow of claim 1 , wherein the controller unit is configured to produce a sound signal to the speakers, wherein the sound comprises at least one of audio sound and anti-noise.

7. A method for abating snoring using an electronic pillow comprising a pillow unit operatively coupled to a reference sensing unit and a controller unit, the method comprising the steps of:

receiving signals via a plurality of error microphones encased in the pillow unit, wherein the error microphones are spaced a first predetermined distance from one another;

receiving at least one signal from at least one reference sensing microphone in the reference sensing unit; and

processing signals received from of the error microphones and reference sensing microphone in the controller unit to reduce noise in an area between the error microphones using a plurality of speakers encased in the pillow unit, where each of the speakers are spaced a second predetermined distance from each of the respective error microphones, wherein noise is reduced in the controller unit utilizing a multiple-channel feed-forward active noise control, and wherein the controller unit processes signals received from at least one of the error microphones to perform acoustic echo cancellation.

8. The method of claim 7 , wherein the controller unit comprises a digital signal processing unit operatively coupled to a phone interface, wherein said acoustic echo cancellation is performed on signals received in the phone interface.

9. The method of claim 8 , wherein the controller unit integrates the active noise control and the acoustic echo cancellation to be performed simultaneously.

10. The method of claim 7 , wherein the error microphones are embedded in a middle third of said pillow unit.

11. The method of claim 7 , wherein the controller unit comprises input channels equal to the number of error microphones and reference microphones, and output channels equal to the number of speakers.

12. The method of claim 7 , wherein the controller unit produces a sound signal to the speakers, wherein the sound comprises at least one of audio sound and anti-noise.

13. An electronic pillow, comprising:

a pillow unit encasing a plurality of error microphones and a plurality of speakers, wherein the error microphones are spaced a first predetermined distance from one another, and the speakers are each spaced a second predetermined distance from each respective error microphone;

a reference sensing unit comprising at least one reference microphone;

a controller unit, operatively coupled to the plurality of error microphones, the plurality of speakers, and the reference sensing unit, wherein the controller unit processes signals received from the plurality of error microphones and reference sensing unit using multiple-channel feed-forward active noise control and acoustic echo cancellation to reduce noise in the space between each of the error microphones using said speakers, wherein the controller unit is configured to integrate the active noise control and the acoustic echo cancellation to be performed simultaneously.

14. The electronic pillow of claim 13 , wherein the controller unit further comprises a digital signal processing unit operatively coupled to a phone interface, wherein said acoustic echo cancellation is performed on signals received in the phone interface.

15. The electronic pillow of claim 13 , wherein the controller unit comprises input channels equal to the number of error microphones and reference microphones, and output channels equal to the number of speakers.
