The sensor includes a transmitter coil adapted to be energized by a high frequency current source and at least two receiving coils. One of the receiver coils generate a sine-like function output signal and the other generates a cosine-like function output signal upon rotation of the coupler. The memory module is operable to compensate for non-sinusoidal output signals caused by a plurality of geometric errors and a gap between the coupler and the at least two receiving coils. The processor module configured to process the non-sinusoidal output signals from both the first and second receiver coils, determine an error in the non-sinusoidal output signals from both the first and second receiver coils, mathematically compensate the assembly to eliminate the error and generates an output signal representative of the rotational position of the coupler.

Inductive sensor module assembly with a center signal processor
Embodiments of the present invention are directed to a novel inductive rotational position sensor that includes a sensor module having transmitting and receiving coils formed on a printed circuit board with a signal processor located in a center area enclosed by the transmitting and receiving coils. This arrangement permits a more compact sensor module. The entire sensor module can be positioned inside a cavity, which has a diameter generally the same as the diameter of the rotational element whose position is being sensed. The arrangement also permits a coupler to be formed on the end of the target. The sensor is concentric with the transfer case shaft and an annulus bore of a transfer case. The sensor is non-contacting and has no movable parts.

A pedal assembly using a non-contacting position sensor utilizing a spring-biased roller on a cam surface to simulate the feel of a conventional brake pedal is provided. The pedal assembly includes an elongated brake support bracket having a cam surface and a pedal arm having a spring-biased roller. A spring-biased roller assembly is mounted to an inward side or beside the pedal arm or on both sides of the pedal arm. The roller assembly includes a fixed leg extending on from an inner side of the pedal arm and a movable leg which is pivotally mounted to the pedal arm. A biasing member extends over the support between the fixed leg and movable leg to generate a biasing force against the roller. When the pedal is depressed, the roller is moved along the cam surface of the support bracket thereby creating the ‘feel’ of a traditional pedal assembly.
