First Claim
Patent Images
1. A method of unlocking an electronic device, the method comprising:
- receiving a sound input from a microphone associated with the electronic device;
determining a first plurality of peak amplitudes associated with the sound input;
determining a first plurality of time intervals associated with the first plurality of peak amplitudes;
determining if the first plurality of peak amplitudes are within a first range defined by a second plurality of peak amplitudes;
determining if the first plurality of time intervals are within a second range defined by a second plurality of time intervals; and
unlocking the electronic device if (i) the first plurality of peak amplitudes are within the first range and (ii) the first plurality of time intervals are within the second range.

Abstract
The present disclosure provides methods and apparatus for unlocking an electronic device. In an embodiment, a process causes a device such as a smartphone to receive a sound input from a fixed position microphone and determine if the device should be unlocked based on a comparison of the sound input with a previously defined sound input.
