Patent ID: 7881749

Claim:
A mobile communication device, comprising: a transceiver configured to communicate wireless signals; memory holding prestored data indicative of an expected flight path of the device, the prestored data comprising a plurality of data values each representative of at least one of position and orientation of the device at a periodic interval along the expected flight path; a motion sensor; processor configured to sample the motion sensor at the periodic interval and generate sampled data indicative of the at least one of position and orientation of the device along an actual flight path of the device; and processor configured to perform a comparison of the actual flight path to the expected flight path and to control an activation state of at least one component of the mobile communication device based on the comparison, wherein the comparison comprises: vector subtracting the sampled data from the prestored data to form difference data indicative of a difference between the actual flight path and the expected flight path, vector summing the difference data to form a vector summation value, and comparing the vector summation value to a predetermined threshold.
