A method for detecting a phase shift in an output signal of an inductive position sensor by calculating the phase spectrum of the position signal based on a Fast Fourier Transformation of the position signal and comparing the calculated phase spectrums over time to detect changes in the phase spectrums.

Method for detecting a phase shift in an output of an inductive position sensor

A control that can be a throttle control of a handle-bared vehicle is presented. According to some embodiments, a control can include a plurality of circuit boards, each of the circuit boards including a transmission coil, sensor coils, and control circuitry the drives the transmission coil and receives signals from the sensor coils; and one or more targets mounted on a shaft and configured to rotate over the sensor coils of the plurality of circuit boards as the shaft is rotated, wherein the plurality of circuit boards are mounted around the shaft, and wherein the position of the target is determined by the control circuitry as the shaft is rotated.
