Abstract

An acoustic spatial diagnostic circuit couples to an array of microphones to successively sample an acoustic environment surrounding a wireless transceiver to generate an acoustic spatial map of activity within the environment based on sets of acoustic samples and execute one or more actions based on a related portion of the acoustic spatial map exhibiting one or more correlations with a spatial context condition of a wireless trained transceiver.

First claim

What is claimed is:

1. A method comprising:
training a smart transceiver with spatial context conditions by sampling an acoustic environment via an array of microphones operatively coupled to the smart transceiver;
generating an acoustic spatial map of activity within the acoustic environment based on sets of acoustic samples;
analyzing the acoustic spatial map to identify a particular acoustic profile in the acoustic environment; and
correlating the acoustic profile to a physical object to determine that the physical object is present in the acoustic environment.

2. The method of claim 1 , further comprising identifying a location of the physical object in the acoustic environment based on the sets of acoustic samples.

3. The method of claim 2 , wherein identifying the location of the physical object in the acoustic environment comprises correlating a known geometry of the array of microphones with at least one of: an amplitude, time, phase, or angle of arrival of the acoustic samples of sounds emanating from the physical object in the acoustic environment.

4. The method of claim 1 , further comprising determining a movement of the physical object in the acoustic environment.

5. The method of claim 4 , wherein determining the movement of the physical object in the acoustic environment comprises:
generating a succession of acoustic spatial maps, each acoustic map of the succession of acoustic spatial maps including a respective location of the physical object in the acoustic environment;
identifying a difference in the respective locations of the physical object in the acoustic environment;
determining, based on the difference in the respective locations of the physical object in the acoustic environment, the movement of the physical object in the acoustic environment.

6. The method of claim 5 further comprising determining a path of the movement of the physical object in the acoustic environment.

7. The method of claim 6 , wherein the path of the movement of the physical object in the acoustic environment is used to predict a future location of the physical object in the acoustic environment.

8. An apparatus, comprising:
a plurality of components coupled to one another to form a transmit and receive path to process wireless communications;
a microphone to receive a set of acoustic samples that relate to an acoustic environment;
