EXPERIENCE:

Engineering Consultant

SENIOR ELECTRICAL/FIRMWARE DESIGN ENGINEER

(September 2000 to present)

Product definition, managing product development. Hardware design of digital, analog, and RF

systems. Board design and layout. Firmware design and coding in C and assembler using mixed

signal processors. DSP implementations.

Some Recent Projects

Developed a controller for a display interface on an ARM based embedded vehicle computer.

Developed the controller firmware to drive a variable speed three phase AC induction motor.

Developed the embedded controller for a HF communication radio. The firmware implemented

the radio functions, implemented audio compression, and utilized multirate and polyphase digital

filter techniques. Developed software defined radio DSP routines to process I Q analytical

signals.

Developed a multi-channel vortex airflow sensor and airflow control system. The system

measured airflow over a wide range of rates with high precision. DSP FIRs were used in the

embedded hardware to improve system performance. The control and sensor system interface

included voltage, current-loop, and BACnet MS/TP network interfaces.

Defining and designing a medical product incorporating a short range RF control link, graphic

display, and capacitive touch button and touch screen interfaces. Defining and designing sensor

systems. Designing and coding twisted pair wire, embedded telephone modem, and wireless

networks.

RAYTHEON MARINE ELECTRONICS, Fort Lauderdale, Florida

SENIOR SOFTWARE ENGINEER Startup Division Developing algorithms and software to

implement sonar and sonar data displays for commercial applications using the ARM

microprocessor and embedded PCs in assembler and C. The sonar data acquisition and

processing front end controlled ping pulse width, power, and repetition rate, log amp receiver

gain, and collected raw sonar data via fast interrupts. Raw data was processed for noise

reduction and signal strength normalization using an adaptive digital filter. The efficient display

algorithms managed screen data using techniques to greatly reduce processor work load.

(October 1999 to April 2000)

CONTROLLED DISTRIBUTION SYSTEMS, Fort Lee, New Jersey

SYSTEM DESIGN ENGINEER Startup Company Designed hardware and software for

multiprocessor networked machines in C and assembler on Motorola and Intel microcontrollers.

Local network packets were transmitted asynchronously using twisted pair. Wider area

communication was via LONTalk firmware based protocol with power line coupling.

(Sept. 1998 to July 1999)

ADVANCED MARINE PROPULSION, Norwalk, Connecticut

SYSTEM DESIGN ENGINEER Startup Company Designed a network controlled electro-

hydraulic fly-by-wire system for Marine applications. The system used Motorola with the LONTalk

protocol.

(June 1998 to Sept. 1998)

WRAY-TECH INSTRUMENTS, Stratford, Connecticut

ENGINEERING PRODUCT MANAGER Directed the full product development of transportation

display, sensor, and control systems. Designed embedded computers to provide multimedia

graphical interactive user interfaces. These products utilized computer networks especially

optimized for critical sensor and feedback control applications in harsh environments. Networked

system components included GPS receivers, RFID, and instrumentation subsystems. Designed

the digital and analog hardware and computer software in assembler and C/C++ using Motorola

and Intel processors. Developed software algorithms for real-time digital signal processing and

data analysis using C and MathCAD. Developed Microsoft device drivers. Developed system

modifications for European markets working directly with these customers abroad.

(August 1992 to April 1998)

ADVANCED TECHNICAL SERVICES Orange, Connecticut

ENGINEERING PRODUCT MANAGER Developed system design, hardware, software, and

firmware for a control and sensor oriented networked multi-processor computer system used to

implement interactive digital video interfaces to banking equipment. The system utilized PC

architecture, Intel digital signal processors, and Motorola microcontrollers. Software developed

included efficient operating system drivers, the first software only real-time digital audio and video

compression and decompression algorithms. Developed asynchronous sensor and control

networks hardware and firmware.

(1989 to 1992)

AMERICAN LIGHTWAVE W allingford, Connecticut

SENIOR ENGINEER Developed communication software and digital hardware for a networked

multiprocessor data communication and video switching systems for fiber two way digital

television. Designed the switching node hardware and firmware in C and assembler using

Hatachi Processors, and central controllers using embedded single board Intel x86 PCs. The

system was developed for GTE for their two way fiber to the home interactive television, phone

and data system. Developed software systems for advanced interactive communications for both

fiber and cable television. Designed the firmware for high production volume settop boxes, and

distribution hubs.

(1979 to 1989)

PERKIN-ELMER CORPORATION Norwalk, Connecticut

SCIENTIFIC PROGRAMMER/SOFTWARE ENGINEER Developed wavefront metrology

programs for optical systems. Worked on the computer simulation of adaptive optic systems and

high energy propagation. Assisted staff research scientists and mathematicians. Wrote numerical

algorithms for embedded systems.

EDUCATION:

UNIVERSITY OF CALIFORNIA Santa Barbara, California

ELECTRICAL ENGINEERING Graduate work in microprocessor system designs, magnetics,

real-time control, and digital signal processing.

UNIVERSITY OF CONNECTICUT Storrs, Connecticut

ELECTRICAL ENGINEERING BSEE/CS Concentrating in electronic circuit design, interactive

graphics, artificial intelligence, and switching theory. Wrote one of the first tournament rated, US

Chess Federation member, chess playing programs. This program used an interactive touch

screen controlled by a graphics coprocessor. The program was the first to incorporated fuzzy

logic for move selection.
