Here are pictures of some of the over 35 IBM
and Lexmark products I
designed/developed, and helped put into mass production since 1990, in roughly
chronological order.

Controller Card for
Lexmark X820e MFP
|
My Controller Card for the Lexmark X820e MFP won 3rd place (Consumer
Electronics division) in the 2002
Mentor Graphics Technology Leadership Awards. This card has a 350MHz x86
microprocessor, can take up to 1GB of 100MHz SDRAM, and has 950 components in
the schematic, of which about 850 are populated. It went into production on
its second spin-- fully functional and meeting international
requirements for product safety, electromagnetic compatibility (EMC),
electromagnetic interference (EMI), and electrostatic discharge (ESD)
immunity.
Below is what the first spin of this card, the Engineering Verification Test
(EVT) version, looked like. We got the first card working one week after
building 20 EVT cards. A week later we had 18 of the cards working and
ready for programmers and other developers. (We never did manage to get the
last two cards working...) We wound up having to drill out one pin in the
microprocessor socket (to remove a +3.3V-to-ground short), remove two
resistors, cut two traces, and add three short wires to make these EVT cards
fully functional.
Robust Electronic Design, Inc.
is the research arm of
dBi Corporation,
an A2LA-accredited EMC/EMI/ESD testing and
consulting company based in Lexington, Kentucky. Our staff has been directly
involved in putting over 115 major electronic products into mass production at
Sycor, IBM, and
Lexmark, as well as doing the EMC/
EMI/ ESD engineering tests and FCC/ CE-Mark approval tests for over 70 products
and testers developed by clients--bringing them into compliance with both
domestic and international laws and standards. Our staff has also served as
expert witnesses in two lawsuits, one involving a personal-injury case, and
the other involving semiconductor patent law. We have over 31 years
experience in the computer and electronics industries developing electronic
products and electronic equipment that:
- Work.
- Are safe and reliable.
- Can be manufactured, tested, repaired, and serviced economically.
- May be sold and used worldwide.
- Can be easily adapted/enhanced to meet new and changing requirements.
Our President, John R. Barnes, is a Professional Engineer licensed in the
state of Kentucky, a NARTE-Certified
Electromagnetic Compatibility Engineer, a
NARTE-Certified Electrostatic Discharge Control Engineer, a Senior Member
of the IEEE, and an
Advanced-class amateur radio operator. He has written three books,
Electronic System Design: Interference and Noise Control Techniques,
that was published in English and Russian, and Robust Electronic Design
Reference Book, Volumes 1 and 2, which came out in March 2004. He has
also written articles on designing electronics for electrostatic discharge
(ESD) immunity for
Printed Circuit Design and
Conformity magazines.
