I have finished an interface box (8031 microcontroller, oscillators, etc.)
to control the firing of the ultrasonic transmitters on the Glove. The
signals from the receiver array are passed through the junction box, 
which has level-testing op-amps that convert the oscillating waveform into
a TTL-compatible gate signal. I am using a counter onboard the 8031 to 
determine the time-of-flight of the signal.

Everything works fine, EXCEPT that the distances that I get are very noisy:
variation of 200 microseconds (about six inches) at a distance of five feet.


Question: Does anyone else have this problem ? I haven't seen much on the 
net about the Glove lately.
