Systems Engineering: Created architectural alternatives for redesign of existing semiconductor wafer sorters to improve reliability and maintainability. Performed the systems level design of an optical inspection module for wafer sorters. Created a conceptual design of the control electronics of 300mm semiconductor wafer sorters. Oversaw redesign of an ISA bus 4-axis stepper motor control board with vacuum sensors to eliminate obsolete parts and improve reliability.

Detailed Design: Developed ESD immunity improvements to wafer sorters that quadrupled system-level mean time between failures. Designed a 4-axis motion control interface board with vacuum sensors and vacuum solenoid drivers. Designed an intelligent embedded controller including processor, sensor interface and motor drivers for a servo-driven wafer indexer. Designed a PC104 interface board for Windows NT based motion-control applications. Developed many modifications to standard systems to meet specific customer requirements. Geospace Research, Inc. El Segundo, CA.

Systems Engineering: Lead hardware designer for a 139 MHz scientific radar system, including selection and integration of off-the-shelf RF components, coordination of mechanical design, interface with software designer and project scheduling. Designed document control and parts standardization systems.

Detailed Design: Designed a 300W power amplifier and a digitally controlled phase shifter for scientific VHF phased array radar. Designed and implemented digital and RF experiment-specific interface circuitry for the Arecibo Observatory=s HF atmospheric heater.

Standard Communications Corporation, Torrance, CA

Systems Engineering: Lead the systems design team for Standard Communications? revolutionary ?Stratum? television modulator system. Lead systems designer for ALM1000 modulator system and CAM830 satellite receiver remote control. Initiated numerous improvements in the configuration control procedures.

Detailed Design: Designed the backplane for the Stratum TV modulator system, routing digital control, analog video, TV IF (45 MHz) and RF (55 - 550 MHz) signals including signal switching for automated backup for 8 cable TV modulators. Designed a reference oscillator PCB for Stratum modulator system. Designed a PCB used to send and receive FSK digital data on the aural Detailed Design: Designed the backplane for the Stratum TV modulator system, routing digital control, analog video, TV IF (45 MHz) and RF (55 - 550 MHz) signals including signal switching for automated backup for 8 cable TV modulators. Designed a reference oscillator PCB for Stratum modulator system. Designed a PCB used to send and receive FSK digital data on the aural subcarrier of an analog TV modulator and demodulator. Repackaged the TVM450 19" rack-mounted modulator into ALM1000 AVME-style@ modulator. Designed the CAM830 remote control and CPL840SIS back-porch clamp options for MT830 satellite receiver.

Lockheed Aeronautical Systems Co. Burbank, CA.

Systems Engineering: Integrated the communication systems on the ES-3A aircraft including HF, VHF, UHF and SATCOM radios, IFF, link-4 and link-11 data links and digital intercom.

Detailed Design: Found & fixed a design flaw in S-3A wing rack driver, preventing inadvertent weapons release. Designed radar-blanking system for ESM receivers (ES-3A aircraft). Investigated the feasibility of using hard-wired T connections for bus couplers on 10 MHz manchester LAN (ES-3A aircraft).
