I am trying to get in contact with persons interested in interfacing sensors
for VR systems. My company Atmos Technology in San Jose Ca has developed a
single chip sensor interface circuit  for silicon and other types of sensors.
The chip is self contained and its major features are:

          EEPROM memory for calibration and on chip trim
          12 bit A/D converter
..............Pulsed constant current source for sensor excitation
          Differential amplifier
.............Supply voltage  2.7 to 6 volts
..............Standby current consumption is less than 1 micro-amp
..............Max sample rate 500 Hz
..............Temperature compensation

I am fairly new to the internet and feel that this posting my be pushing the
non commercial limitations. If I have overstepped please let me know.  We are
very proud of this circuit and have been using it for some time in consumer and
industrial products. 

I would be interested in discussing possible applications for this chip.
