Employment Resume – long form – 1992 – present
Member of the Research Staff, Interval Research Corp., Palo Alto CA, 1992 – 2000.
Tools used: ORCAD Capture, PADS-PCB layout, Tektronix DSO,
First researcher hired at Paul Allen’s R&D laboratory. Participated in planning for building layout, hiring of researchers, formation of Intellectual Property Committee. Managed project to develop prototypes for researchers. Participated in the design of:
- Portable multi-channel high-precision data logger with networking capability.
- Game board having 2D pattern of contacts allowing an electrical circuit to be maintained at all times to a sliding counter.
- Real-time video processing system for edge detection. FPGA, PLD sync generator, CMOS line buffer memories.
- Breath-sensitive 2D sensor for an art project, subject of patent. Used discrete transistors as low-cost temperature sensors.
- “Pocket Watch” video display for wearable camcorders. Developed analog polarity-equalizing circuit.
- 500-watt servo amplifier using high-power operational amplifiers. Burnout problems were solved by designing a variable-transconductance amplifier and tuning it to match the transmission-line characteristic impedance of the motor cables.
- Crystal-locked motor controller for rotary camera positioner.
Served as engineering liaison to an Interval spinoff company. Traveled to England to transfer technology of magnetic 2D position and identity sensor. Advised and assisted spinoff company Managed a prototype construction run which allowed them to show product at the Toy Fair reliably.
Interval Research was closed by Paul Allen in April 2000.
President, Golemics, Inc. 2000 – 2001
Designed and built an image capture system utilizing electrostatic pickup on a large grid array of electrodes, receiving 100 KHz signal by homodyne detection. Wrote a complex machine-language program for the PIC-based controller. Designed all printed circuits and debugged. For Aura Imaging, Redwood City 2000 – 2001. CMOS logic and switches, PIC16C7X embedded CPUs, phase locked loops, quadrature homodyne signal detection.

Performed development of “Soundpaper” system for creating and reading 2D barcodes containing compressed speech (for LTT LLC, 2005 – 2006). Assembled a team of consultants as needed, managed the project and performed electronic development. Client terminated project due to lack of funds, but the outline of the solution was created and the recording section completed. Technologies included DSP chip, video sensor chips, thermal transfer printers, audio compression and image recognition and processing.
Performed upgrade of design of a pharmaceutical piston extruder device, moving from a hard-wired controller to an embedded processor design. Managed the project, specified and designed the controller embedded computer, wrote software specifications and flowchart, subcontracted mechanical work and software development to outside contractors, designed user interface and purchased parts. Performed system assembly including wiring harnesses, debug and checkout. Wrote operating procedure. For Talima Therapeutics, Santa Clara, CA, 2007.
