Abstract
A tracking device may be used to detect a position or movement of an object. The tracking device may include a housing that supports an emitter. The emitter may transmit a first signal. A measurement device within the housing may measure rotational movement of an object. Circuitry may receive a second signal in response to the first signal. The circuitry may reset an angle value to a predetermined value based on the second signal. The angle value may be determined by a measurement of the rotational movement of the object.
