Bud Volberg received his B.S. in Electrical
Engineering from the University of California. He is
the president of Invotron, Inc. His past
experience includes president of
Acoustic Systems, Inc., chief scientist
of Integrated Sciences Corp. Senior
Scientist for the Naval Ocean Systems
Center, founder of AMETEK
Electronics Division, and head of
solid-state research for Stromberg-Carlson.
Throughout his career, he has been a consultant to
major corporations and government. He has
participated in the design and development of ASW
sonars and MCM sidelooking, forward looking, and
bathymetric sonar systems. Other work has involved
the design of mine neutralizers, undersea work
systems, waterside security, and under-ice sonars.
Garry A. Kozak attended Wayne State University,
Detroit, majoring in Electrical Engineering. He has
over 30 years of service to the
oceanographic community, including
28 years in search and survey
operations with side scan sonar. For
the past 25 years he has been
employed by Klein Associates, one of
the leading manufacturers of side scan
sonar systems. He has specialized in
M.C.M. and C.O.O.P application of side
scan sonar and has over 24 years of hands-on
experience in detecting mine-like objects.
