Its function is to serve voice prompts ("Please state your name") record and store short-term voice ("John Doe") and record conferences for long-term storage. The AEM is capable of simultaneously recording and playing back 1000 voice streams.

Erbium-Doped Fiber Amplifier Control Control circuits for EDFA system monitoring four pump lasers for TEC power bias as well as input output and gain of the Fiber Amplifier. System employs Digital Signal Processing with custom algorithms for monitor decision making and control.

PCS Cellular Base Station Transceiver PCS Cellular Base Station Equipment design includes a set of eight single-channel transmitters and two full-band receivers.

Water & Oil Content Anaylyzer Explosion-proof oil well-head test system to determine fresh-water and salt-water content of oil-water mixture pumped at well site. Measured down to 5 femtofarads capacitance and 0.1Meg to 1Meg impedance at a rate of ten times per second and then provided data via RS-232 port to central computer.
