Summary:
I have a wide range of electronic design and management experience, and a
wide range of interests. My professional career includes over thirty years of
diverse electronics industry experience progressing through the ranks as
electronic design engineer, engineering manger, department manager and as
president of a small electronics corporation.
My electronic design experience ranges from low level analog design, to
ultrasonics, high power switching regulators, control systems, aerospace
systems, medical electronics and RF design.
I have been active in digital design since the beginning of the
microprocessor era when I wrote in assembly language for the Intel 4004 and RCA
Cosmac. Current projects are being written in C code for PIC microcontrollers,
and Visual Basic for the PC.
I enjoy working with customers and working in a team effort to achieve
timely, high quality results and also enjoy employee mentoring.

PRESIDENT, CO-FOUNDER and CHIEF ENGINEER-
Growing to annual sales of around $3 million, we
created a company that was fun for several years, but then became too routine
for such entrepreneurial types, so we sold the company in January 1997. At our
peak, we had seven full-time employees, and made extensive use of local assembly
shops rather than adding more employees.
Electronic designs included ISA bus data
communication boards for use in a PC, I2C bus interface cards, electronic design
of digital servo control loops for small DC motors using 8051 family processor,
and some C language programming for the mathematics of the digital servo control
loops.
