1. A method for acquiring inertial sensor data for a mobile device, the method comprising:
- receiving a plurality of signals generated by a plurality of sensors adapted to detect physical movement of a mobile device with respect to a plurality of coordinate axes; and
delaying a time at which at least one of the received signals is digitized based on predefined processing delays associated with one or more of the plurality of sensors to provide an output of digitized versions of the received plurality of signals synchronized with respect to a common point in time.

Abstract
The subject matter disclosed herein relates to a system and method for receiving a plurality of signals generated by a plurality of sensors adapted to detect physical movement of a mobile device with respect to a plurality of coordinate axes. A time at which at least one of the received signals is digitized is delayed to provide an output of digitized versions of the received plurality of signals synchronized with respect to a common point in time.
