Abstract
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.
Claims16
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.
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.
