John R. Barnes' second and third books,
Robust Electronic
Design Reference Book, Volumes I and II are now available from
Springer, which merged with
Kluwer Academic Publishers in July 2004. The ISBN for the hardbound set is
1-4020-7739-4, and the list price is $495.00 (US)-- although you can now find
it for considerably less on the Internet. The two books total 1,736
pages, with 194 tables, 663 illustrations, and a 106-page index covering over
9,200 design/ development/ manufacturing problem areas that may arise in
getting from that "first fuzzy idea" to a product in mass production, or a
piece of equipment in service. In 2005, John received a Division Technical
Achievement Award from the
ARRL for writing these books. You can
read a sample chapter by going to
Chapter 17. Further information on these books is available at:
John's most recent article,
"Designing Electronic
Systems for ESD Immunity", was published in the February 2003
Conformity magazine
(vol. 8 no. 1, pages 18-27). This is a condensed version of his two-part
article
"Designing Electronic
Equipment for ESD Immunity" which was published in the July 2001
Printed Circuit Design magazine (vol. 18 no. 7, pages 18-26) and
"Designing Electronic
Equipment for ESD Immunity Part II," which appeared on the
pcdmag.com web site in November 2001.

dBi Corporation was a
one-man test house (testing laboratory) based in Lexington, Kentucky, testing
a wide variety of commercial electronic products for electromagnetic
compatibility (EMC), electromagnetic interference (EMI), and electrostatic
discharge (ESD) under its ISO 17025 accreditation. dBi was founded in
Winchester, Kentucky in 1995 by Donald R. Bush, shortly after he retired from
30 years service with IBM Lexington's/ Lexmark's EMC Lab. John R. Barnes,
who'd worked with Don at IBM Lexington and Lexmark, bought dBi in 2002
after Don's death, and moved the company to Lexington, Kentucky. John closed
dBi at 11:59pm EDT on September 30, 2013, because ObamaCrap had
increased operating expenses to the point that we could no longer afford to
remain in business.
We'd like to thank all of the clients who chose dBi to test their
products from 1995 to 2013. Below is a brief summary of our accomplishments
during the 18 years we were in business.
From 1995 to 2001, under Don Bush's ownership and operation, dBi:
- Did the official approval testing of 141 products developed by 20
client companies.
- Did the official FCC/ Industry Canada (IC) Verification and Declaration
of Conformity (DoC) testing of 92 products.
- Did the official FCC/IC Certification testing of 15 products.
- Did the official CE Marking testing of 100 products.
From 2002 to 2013, under John Barnes' ownership and operation, dBi:
- Tested 389 products and 2 testers developed by 44 client companies.
- Did the official approval testing of 357 products and 2 testers, getting
all but 4 of them to meet all of the FCC, Industry Canada
(IC), CE Marking, C-Tick, and Regulatory Compliance Mark (RCM) standards
and requirements for their desired market areas.
- Did the official FCC/IC Verification and Declaration of Conformity (DoC)
testing of 296 products.
- Did the official FCC/IC Certification testing of 24 products.
- Did the official CE Marking testing of 271 products and 2 testers.
- Did the official e-Mark testing of 3 products.
- Did the official Australia/New Zealand Verification testing of 170
products.
- Co-sponsored John's writing the
Robust Electronic Design Reference Book,
Volumes I and II.
- Served as an expert witness on electronics in three lawsuits.
