Patent Images
1. A method, comprising:
- in an electronic device comprising first and second processors, obtaining audio input corresponding to sound propagating within an aural environment surrounding the electronic device;
at a first processor, processing the audio input to discern a characteristic of the audio input, the processing comprising processing audio input samples of the audio input to determine a relative-entropy of the audio input, and estimating the presence of audio activity based on the determined relative-entropy of the audio input;
generating an output based upon the processing of the audio input to discern the characteristic; and
causing the second processor to enter into a higher power state based on the generated output.

Abstract
Methods and arrangements involving electronic devices, such as smartphones, tablet computers, wearable devices, etc., are disclosed. One arrangement involves a low-power processing technique for discerning cues from audio input. Another involves a technique for detecting audio activity based on the Kullback-Liebler divergence (KLD) (or a modified version thereof) of the audio input. Still other arrangements concern techniques for managing the manner in which policies are embodied on an electronic device. Others relate to distributed computing techniques. A great variety of other features are also detailed.

20. A non-transitory computer readable medium, on which is stored instructions, which configure a first processor to:
-
obtain audio input corresponding to sound propagating within an aural environment surrounding an electronic device; process the audio input to discern a characteristic of the audio input by determining a relative-entropy of the audio input, and estimating the presence of audio activity based on the determined relative-entropy of the audio input; generate an output based upon the processing of the audio to discern the characteristic; and cause a second processor to enter into a higher power state based on the generated output. - View Dependent Claims (21, 22, 23, 24)
