PROFESSIONAL EXPERIENCE
 ZEBRA TECHNOLOGIES, INC.(formerly Multispectral Solutions, Inc.), Germantown, MD 1999-present

Zebra Technologies is a publicly held corporation present in over 100 countries with over $1B in sales focused on delivering innovative asset identification solutions for business improvement and security applications. In 2008, Zebra acquired Multispectral Solutions, which had developed ultra wideband (UWB) technology for real time tracking of personnel and assets.

Chief Scientist(1999-present)

Developed circuitry and architectures for a variety of communication and locating systems based on short-pulse electromagnetics. Assisted in the transition of several UWB-based systems from SBIR projects through to commercialization. Activities have included:

$\bullet$
Development of system architecture and initial software for the Sapphire commercial real-time locating system (RTLS). Sapphire uses time-difference-of-arrival (TDOA) principles to track positions of small low-power tags intended to be attached to various assets.
$\bullet$
Transmitter and receiver design from HF through K-band. Particular emphasis on C-band UWB electronics for the Sapphire RTLS tracking system. Developed extremely low power transmitters and cost-effective receivers down to the discrete component level. Particular emphasis on power consumption, noise figure, gain flatness, temperature compensation, and transmit power.
$\bullet$
Obtaining FCC Part 15 certification for both intentional and unintentional emissions. Worked with test labs to perform certification measurements. Developed appropriate EMI suppression for both digital and RF circuitry.
$\bullet$
Oversight of intellectual property matters. Very familiar with the patent prosecution process.

 XEROX PALO ALTO RESEARCH CENTER, Palo Alto, CA 1987-1999
Xerox PARC was an industrial research laboratory operated by Xerox Corporation which covered a wide variety of disciplines including computer science, materials, imaging, and human-computer interface.

Member of Research Staff(1987-1999)
$\bullet$
Developed processes and electronics for an electrophoretic display technology
$\bullet$
Developed RF electronics for several experimental wireless LAN technologies
$\bullet$
Developed much instrumentation, high speed and high voltage electronics for various printing technologies
PATENT DEVELOPMENT AND MARKETING CORPORATION, Design of all electronics and software for a blood-pressure measurement instrument.
