SYSTEMS AND METHODS FOR DETERMINING LOCATION OF A MOBILE DEVICE BASED ON AN AUDIO SIGNAL
First Claim
1. A mobile device comprising:
- an enclosure sized and shaped such that the enclosure is readily transported on a person of a user of the mobile device;
a display within the enclosure;
a microphone within the enclosure for receiving an audio signal from an audio signal source; and
a controller within the enclosure, coupled to the microphone and the display, and configured to;
based at least on information included in the audio signal, determine a delay between a transmission of the audio signal from the audio signal source to receipt of the audio signal by the microphone;
based at least on the delay, determine a geographical location of the mobile device; and
based on the geographical location of the mobile device, display geographical information to the display indicative of the geographical location.

Abstract
A mobile device includes a display, a microphone, and a controller all within an enclosure sized and shaped such that the enclosure is readily transported on a person of a user of the mobile device. The microphone is configured to receive an audio signal from an audio signal source. The controller is coupled to the microphone and the display, and configured to, based at least on information included in the audio signal, determine a delay between a transmission of the audio signal from the audio signal source to receipt of the audio signal by the microphone. The controller is further configured to, based at least on the delay, determine a geographical location of the mobile device. The controller is also configured to, based on the geographical location of the mobile device, display geographical information to the display indicative of the geographical location.
