Hi, I'm Professor Robert (Bob) A. Stevenson, Engineering Department Chairman,  and I have taught in the ELAC Engineering Department since 1975.
My wife of 31 years, Lynne, is a third grade teacher.  My daughter (Jennie) and my son (Ryan) are both graduate engineers (Jennie-UCLA, Ryan-USC).  They are both presently in grad school working toward their Ph.D. degrees.

    Education

I received my BS degree in Electrical Engineering and my MA degree in Education from California State University Los Angeles.  I am a Licensed Professional Electrical Engineer (PE) in the state of California.

    Industrial Experience 

As a consultant, I regularly perform Electromagnetic Interference and Electromagentic Compatibility (EMI/EMC) consulting work for Maxwell Energy Products, Inc., a Maxwell Technologies Company.  Since 1969, I have held various technical and managerial positions involving EMC, EMI filter and capacitor design and manufacturing.  Past titles include: Vice President of Engineering and Technical Marketing for Sierra Aerospace Technology Corp., co-founder and Vice President of Engineering for US Microtek Components Corp., Vice President of Engineering for U.S. Capacitor Corp., Director of Technical Marketing for Unitrode Corp., Passive Components Div., Chief Filter Engineer at Centralab Electronics Corp., EMI/EMC Engineer at Litton Data Systems, and EMI Test Lab Supervisor at Stoddart Electro Systems.

    Military Service

I spent four years in the U.S. Navy where I was a qualified aircrewman. I flew as a radio operator on P2V type antisubmarine airplanes during the 1960s (we hunted Russian submarines and trawlers all over the Pacific Ocean).

    Inventions and Patients

I am an inventor or co-inventor of 10 U.S. patents (plus 8 pending) in the area of Electromagnetic Interference (EMI) filter designs for use in cardiac pacemakers, implantable defibrillators, cochlear implants and other medical devices.  Many cardiac pacemakers and implantable defibrillators produced in the U.S. today incorporate one or more of these EMI filter designs which offer a very high degree of attenuation/immunity to interference from cellular phones, microwave ovens, and other emitters.  I also do consulting/design work on cochlear (ear) implants, neurostimulators and muscle actuators.

    Publications

I have given over 30 published technical papers at conferences around the world on Electromagnetic Interference Control with an emphasis on implantable medical devices.  The 1999 Interference Technology Engineer’s Master (ITEM Magazine) published a feature article that I wrote on EMI control in cardiac pacemakers.  Over the last  three years I have presented FDA invited papers at the Institute of Electronic and Electrical Engineers-Engineering in Medicine and Biology Symposiums (IEEE-EMBS) held in Chicago and Hong Kong in addition to several other technical papers at conferences in Prague, Lisbon, New Orleans, and London.  Six times my papers have won “Best” or “Outstanding” awards at such conferences.

    Professional Association

I  have been a regular participant in the Association for the Advancement of Medical Instrumentation (AAMI) Pacemaker EMI Task Force which meets three to four times yearly.  This committee has been drafting a  new standard (PC69) to insure that pacemakers and implantable defibrillators will be not malfunction in the presence of EMI from cell phones, retail store security systems , electrical surgery knives and other emitters.

    NASA

I was also a consultant to NASA.  I was the primary author of the EMI filter and ceramic capacitor specifications for the new Space Station.

    I am also proud of the following:

1.  On March 13, 1997 at the American Society for Engineering Education (ASEE) annual meeting,  I received the “ASEE-PSW Outstanding Community College Educator” award.

2.  At the 14th Annual Awards Banquet held October 24, 1996 at the University of Southern California, I was awarded the Chicanos for Creative Medicine “Teacher of the Year Award.”

3.  On October 3, 1996 I gave two live interviews on KWHY Television, “Health News Update” and “Market Watch.”  The subject was “EMI filters that protect Cardiac Pacemakers and Implantable Defibrillators from Cellular Phone Interference.”

4.  On December 5, 1995, I appeared on a nationally televised live videoconference hosted by Dr. Ray Landis, Dean of Engineering, California State University Los Angeles.  The broadcast was sponsored by the National Science Foundation (National Technical University).  The topic was a faculty forum titled "Enhancing Student Success through a Model Introduction to Engineering Course."

5.  On March 24, 1994, I received the “1993 Distinguished Alumnus Award” from California State University Los Angeles-School of Engineering and Technology.
