Re: Ted Noel's comments about the patent on the position sensor circuitry,
you're most probably right. If anyone knows how to search files at the
patent office, and would like to use the thing, contact me and I'll try to
dredge up the info. (No guarantees though, I've been in my new house since
September and there still are many unpacked boxes!) I think I called it (in
the patent papers) "A Zero Degree Position Sensor". It was granted a patent
around the 1971 - 73 time-frame. Whether it can be applied as a static
position sensor would take a little investigation. That was a long time ago
and the memory does grow a bit foggy over time.
