Title:
【発明の名称】磁気増分運動検出システム
Document Type and Number:
Japanese Patent JP2003504632
Kind Code:
A
Abstract:
A magnetic incremental motion detection system for outputting a plurality of voltage and/or current signals in analog or 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 at least one analog signal in response to a synchronous movement of the target with the object. The outputted analog signals have the same duty cycle, and are consistently out of phase with each other by the same degree.
