Motion of a device is sensed using image data, and a gesture corresponding to the sensed motion of the device is recognized. The pulsed carbon plasma apparatus of the invention comprises a carbon plasma flow scanning device having at least one pair of deflecting coils, where the deflecting coils have, in the scanning plane, a different number of turns on opposite sides. The first portion is formed of a material effective to produce a relatively large hole in an explosive reactive armor faceplate.
