ABSTRACT:
A control system includes a device having a position between minimum and maximum positions. First and second position sensors sense the position of the device and generate first and second position values. A sensor module generates a first signal waveform based on the first position value and a second signal waveform based on the second position value. The sensor module varies a frequency of the first signal waveform based on the first position value and a frequency of the second signal waveform based on the second position value. A control module communicates with the sensor module and determines the first and second position values based on the frequencies of the first and second signal waveforms, respectively. The sensor module increases the frequency of the first signal waveform and decreases the frequency of the second signal waveform as the device moves from the minimum position to the maximum position.
