Patent ID: 7383120

Claim:
A sensor module adjustment circuit, comprising: a device having a position between minimum and maximum positions; first and second position sensors that sense said position of said device and that generate first and second position values, respectively; a sensor module that includes: a first signal conversion module that generates a first signal waveform based on said first position value, that varies a frequency of said first signal waveform based on said first position value, and that includes a first gain module; a second signal conversion module that generates a second signal waveform based on said second position value, that varies a duty cycle of said second signal waveform based on said second position value, and that includes a second gain module; and a gain magnitude module that communicates with said first and second gain modules and that determines first and second signal gains of said first and second gain modules, respectively; and a signal preset module that communicates with said gain magnitude module and that adjusts said first and second signal gains so that said first and second signal waveforms are equal to first and second predetermined signal waveforms, respectively, when said position of said device is fixed.
