CIRCUITS AND METHODS FOR GENERATING A THRESHOLD SIGNAL USED IN A MOTION DETECTOR IN ACCORDANCE WITH A LEAST COMMON MULTIPLE OF A SET OF POSSIBLE QUANTITIES OF FEATURES UPON A TARGET

摘要

The circuit for detecting the motion of an object may include a threshold selection module or a peak selection module using one or more threshold signals identified prior to the current cycle of the magnetic field signal to implement the threshold signal used for the current cycle of the magnetic field signal, Provides an identifier module. Methods associated with the circuit are also described. The circuit and method may be adapted to store values associated with a least common multiple of a set of possible quantities of detectable features on the target objects.
