Apparatus, system and method for noise cancellation and communication for incubators and related devices
Systems, apparatuses and methods for integrating adaptive noise cancellation (ANC) with communication features in an enclosure, such as an incubator, bed, and the like. Utilizing one or more error and reference microphones, a controller for a noise cancellation portion reduces noise within a quiet area of the enclosure. Voice communications are provided to allow external voice signals to be transmitted to the enclosure with minimized interference with noise processing. Vocal communications from within the enclosure may be processed to determine certain characteristics/features of the vocal communications. Using these characteristics, certain emotive and/or physiological states may be identified.
1. An enclosure, comprising:
a noise cancellation portion, comprising a controller unit, operatively coupled to one or more error microphones and a reference sensing unit, wherein the controller unit processes signals received from one or more error microphones and reference sensing unit to reduce noise in an area within the enclosure using one or more speakers; and
an external voice input apparatus operatively coupled to the noise cancellation portion, wherein the external voice input apparatus is configured to receive external voice signals and reproduce the external voice signals on the one or more speakers, wherein the external voice signals are external to the area within the enclosure,
wherein the external voice input apparatus comprises a sound analyzer configured to analyze the external voice signals and determine whether the external voice signals are desired speech signals.
2. The enclosure of claim 1 , wherein the desired speech signals are a parent's voice.
3. The enclosure of claim 1 , wherein the external voice input apparatus further comprises a transmitter and wherein the controller unit reproduces the desired speech signals using the one or more speakers.
4. The enclosure of claim 3 , wherein the reference sensing unit includes a microphone for receiving the external voice signals.
5. The enclosure of claim 4 , wherein the microphone is a wireless microphone that is not placed on or within the enclosure.
6. The enclosure of claim 1 , wherein the external voice input apparatus is further configured to receive an interior audio signal, wherein the interior audio signal originates inside the enclosure.
7. The enclosure of claim 6 , wherein the controller unit of the enclosure, based on the interior audio signal, detects an emergency noise.
8. The enclosure of claim 7 , further comprising a transmitter;
wherein the enclosure, in response to the emergency noise, sends an emergency message via the transmitter.
9. An incubator for reducing unwanted noises and reproducing desired voice signals, the incubator comprising:
an interior space within the incubator;
a noise reduction portion, comprising:
one or more speakers;
an error microphone;
a reference sensing unit; and
a controller unit operatively coupled to the error microphone and the reference sensing unit, wherein the controller unit processes signals received from the error microphone and the reference sensing unit to reduce unwanted noise in the interior space using one or more speakers; and
a communication portion configured to reproduce a desired voice signal within the interior space, wherein the communication portion is operatively coupled to the noise reduction portion and wherein the desired voice signal originates outside of the incubator;
wherein the communication portion comprises a receiver configured to receive an external audio signal;
wherein the external audio signal originates outside of the incubator; and
wherein the communication portion comprises a sound analyzer configured to analyze the external audio signal and determine whether the external audio signal is the desired voice signal.
10. The incubator of claim 9 , wherein the desired voice signal is a parent's voice.
11. The incubator of claim 9 , wherein the communication portion further comprises a transmitter that transmits the desired voice signal to the controller unit, and wherein the controller unit reproduces the desired voice signal using the one or more speakers.
12. The incubator of claim 11 , wherein the reference sensing unit includes a microphone for receiving an audio signal.
13. The incubator of claim 12 , wherein the microphone is a wireless microphone that is not placed on or within the incubator.
14. The incubator of claim 9 , wherein the communication portion is further configured to receive an interior audio signal, wherein the interior audio signal originates inside the incubator.
15. The incubator of claim 14 , wherein the controller unit of the incubator, based on the interior audio signal, detects an emergency noise.
16. The incubator of claim 15 , further comprising a transmitter; and
wherein the incubator, in response to the emergency noise, sends an emergency message via the transmitter.
