Abstract
A magnetic incremental motion detection system ( ) for outputting a plurality of voltage and/or current signals in digital form wherein the voltage and/or current signals are a collective representation of any incremental rotational, linear, or pivotal movement of an object. A target ( ) of the system ( ) is adjoined to an object to synchronously move with the object. A plurality of indications ( ) are adjoined to the target ( ), and uniformly and serially disposed along an area ( ) of a surface ( ) of the target ( ). The system further comprises one or more magnetic sensors ( ) spatially positioned from the area of the surface to define air gap areas therebetween. Each of the magnetic sensors ( ) are operable to output an analog signal in response to a synchronous movement of the target with the object, and one of two digital circuits ( ) output a digital signal in response to the analog signal. The circuitry includes means for compensating for offset in the output signals of the magnetic sensors.
