Patent ID: 8655615

Claim:
An absolute high resolution segment or revolution counter, comprising: a shaft; at least one moving excitation magnet affixed to said shaft; a Wiegand element, said Wiegand element includes a ferromagnetic element; a rotation counter; said rotation counter having a non-volatile data memory; a first sensor, said first sensor includes an induction coil wound around said ferromagnetic element, said induction coil provides a first output, said first output provides an output current; a second sensor, said second sensor provides a second output; a third sensor for fine resolution of a revolution, said third sensor provides a third output; a control logic device for processing said first output from said first sensor and said second output from said second sensor; an energy storage circuit; a power controller in electrical communication with said first output of said first sensor, said second sensor, said rotation counter, and said energy storage circuit; said power controller operating without external electrical energy, said energy storage circuit receiving energy from said first sensor; a μ-controller for analyzing fine resolution information from said third output of said third sensor, said μ-controller in electrical communication with said control logic device and said power controller; at least one of said: Wiegand element, said first sensor, said second sensor, said third sensor, said control logic device, said energy storage circuit, said power controller, said rotation counter having a non-volatile data memory, said third sensor for fine resolution of a revolution, and, said μ-controller, is integrated into an integrated circuit in a chip/semiconductor substrate; analog signals of said third sensor are error corrected in said μ-controller for fine resolution by means of a Fourier analysis increasing the accuracy of said signals; and, said rotation counter determines the number of revolutions and position of said shaft.
