AUDIO-BASED DEVICE CONTEXT DETECTION
This abstract first appeared for US patent application 20250076496 titled 'AUDIO-BASED DEVICE CONTEXT DETECTION
Original Abstract Submitted
systems and methods are provided for an acoustic-based determination that a device is inside a bag, enabling a device to react early to a potential hot bag scenario before the device begins to overheat. acoustic cues associated with the device being put in a bag can be detected, and an ultrasonic echo can be analyzed to identify characteristics of reflections from a bag material. ambient acoustics are used as a cue for hot bag detection, and acoustic analysis can be implemented in an audio digital signal processor, consuming a minimum amount of energy and allowing the acoustic-based device context detection method to function when the device is in standby, sleep, and/or hibernate mode. when the acoustic-based device context detection method determines that the device is inside a bag, the method prevents the device from entering a high power state, providing users with worry-free battery life.
