SYSTEMS AND METHODS FOR DETECTING DRIVER PHONE USE LEVERAGING CAR SPEAKERS
First Claim
1. A method for determining a location of a device in a space in which a plurality of external speakers are disposed, comprising:
- receiving, by a single microphone of the device, a combined audio signal defined by a discrete audio signal output from a plurality of external speakers;
analyzing, by the device, the combined audio signal to determine the location of the device within the space.

Abstract
Systems and methods for determining a location of a device in a space in which speakers are disposed. The methods involve receiving a Combined Audio Signal (“CAS”) by an MCD microphone. The CAS is defined by a Discrete Audio Signal (“DAS”) output from the speakers. DAS may comprise at least one Sound Component (“SC”) having a frequency greater than frequencies within an audible frequency range for humans. The MCD analyzes CAS to detect an Arriving Time (“AT”) of SC of DAS output from a first speaker and an AT of SC of DAS output from a second speaker. The MCD then determines a first Relative Time Difference (“RTD”) between the DASs arriving from the first and second speakers based on the ATs which were previously detected. The first RTD is used to determine the location of the MCD within the space.
