Abstract:
1. A control system, comprising: a device having a position between minimum and maximum positions; a first position sensor that senses said position of said device and generates a first position value; a second position sensor that senses said position of said device and generates a second position value; a sensor module that communicates with said first and second position sensors and that generates a single signal waveform based on said first and second position values, wherein a frequency of said waveform is varied based on said first position value and a duty cycle of said waveform is varied based on said second position value; a conductor having a first end that communicates with said sensor module and a second end; and a control module that communicates with said second end of said conductor, wherein said sensor module transmits said waveform to said control module on said conductor and said control module decodes said waveform to determine said first and second position values.
