Resume Addendum Patent, Intellectual Property and Antenna Involvement and Recent

and Current Activities

This is offered as an addendum to my resume. Over the course of my engineering career, I

have been primarily employed as an electronic design engineer, mostly in the areas of wireless

and radio-frequency engineering. I have been self-employed as an engineering design

consultant and contractor and intellectual property and patent consultant since 2002.

In recent years I have designed wireless data transmission equipment, especially for electricity,

water and gas metering and electric utility load-management, feeder automation and Home

Area Network (HAN) applications. I am well versed in wireless networks and antenna design for

metering and demand-side management applications.

I have extensive experience in the design of embedded antennas for electricity, water and gas

metering, demand-side management, feeder automation, Home Area Networks and in the

Intellectuals Property and patent issues involved in those areas.

Most Recent antenna design activities:

Novel 902-928 MHz notch antenna for electricity meters. US. Patent 7696941.

Small 915 MHz embedded antenna for body-worn personal security device for campus

and industrial security. Patent pending

Dual-band 450 MHz and 915 MHz Notch antenna for Hand-Held Reader Programmer

for Gas meter transceivers. Patent pending

Dual-band 450 MHz and 915 MHz antenna for gas meter transceivers. U.S. Patent

7696941

915 MHz top-loaded Monopole antenna for water-meter pit transceivers. U.S. Patent

7365687

915 MHz Planar Inverted F antenna for electricity meters.

930 MHz embedded antenna for thermostat transceivers.

939 MHz embedded antenna for electric utility load-control devices.

2.4 GHz Planar Inverted F antenna for electric utility 2.4 GHz Zigbee Home area

network devices.

150 MHz embedded small loop antennas for electric utility load-control devices.

850 and 1900 MHz Dual-Band cellular antenna for electric utility metering data back-

haul application

Other antenna designs:

5-Band 14-30 MHz cubical quad HF antenna with single feedline feed! A stellar

performer and one of my proudest accomplishments! Required extensive modeling and

study with NEC-2 Numerical Electromagnetics Code. Met or exceeded model

parameters!

5-element steerable vertically polarized 3.5 MHz parasitic yagi array for long-haul

international work in the 80 meter amateur radio band! Another stellar performer and

very competitive performance on long haul paths into Europe, Middle East. Asia and

Africa. Required extensive modeling with NEC-2 but performed as the models

predicted

7 and 10 MHz dual-band antenna for amateur radio expedition to Howland and Johnston

Islands in the Pacific. The antenna was assembled and tested here in the US, and then

disassembled and packed for shipping to the islands. There it was re-assembled and

erected by the expedition team and it provided excellent world-wide coverage into

Europe, Asia, Africa and North and South America! A great performer! Modeled with.

NEC-2.

Recent and Current Activities and Contracts:

902-928 MHz RF and Antenna Design for Electricity, Water and gas metering Elliott

Tech Holly Springs, NC. Ultimate client was a metering company in Charlotte, NC.

Non-testifying Expert Witness (August. 2011-November, 2011) for Ballard Spahr

Law firm in Atlanta (and several other law firms across the United States) for a

very large case in federal court involving antenna patent infringement claims,

resulting from Transdate filing suit against most of the meter manufacturers and

suppliers and a significant number of utilities in the United States, based on a

patent, that, in my professional opinion, is invalid and has no merit. My first

involvement in this matter was in 2001/2002 on behalf of ABB and Elster Electricity. I

worked with the Woodcock-Washburn law firm in Philadelphia and we apparently

successfully defended against the Transdata claims against ABB and Elster.

Highlights of Qualifications:

40+ years of RF/Electronic and Antenna Design experience.

BSEE with Honors NC State University. 40+ years engineering experience.
