My accomplishments…
Technical Services Manager for International Rectifier. Managed IR’s
maintenance department responsible for all production and test equipment at
their El Segundo semiconductor manufacturing plant. Installed IR’s first Ion
Implantation Reactor for their inaugural HexFET power transistor line.
As head of engineering for Astrophysics Research
Corp (now EG&G Astrophysics), researched and
proved that photo diodes respond to x-rays as well
as visible light and developed the first solid state
photodiode imaging array for airport security X-ray
Scanners. This replaced older photomultiplier
amplified vidicon cameras viewing fluorescent
screens. Applying filters to multiple imaging arrays
our company later developed the first color x-ray
imaging system capable of highlighting weapons and
organic explosives.
For the Astrophysics subsidiary Torr X-ray, implemented photodiode sensing
and regulation electronics to precisely regulate high energy x-ray beams for
NDT test systems. Developed a hand held solid state low level radiation
measuring device to replace Geiger Counters using photodiode technology.
For Astrophysics subsidiary Loyola Industries, developed the first of a kind
computer controlled digital phase control module for multi-phase power
control using SCR and IGBT devices. Originator of 1986 US patent on digital
phase control technique for switched power controls. In those days, we were
still using analog Unijunction Transistors to fire the SCRs and accurate firing
of multiple phases was a bit dicey.
As head of Electrical Engineering for Westech Gear (the old Western Gear of
Everett WA) won a commendation from the US Navy for innovative
accomplishments in designing a prototype robotic cable coiler for coiling
thousands of miles of submarine detection cable into shipboard and land-
based cable storage tanks.

For Westech Heavy Machinery Division designed several computer controlled
coordinated pipe tensioning systems for laying submarine oil and gas
pipelines. The largest system spanned a floating platform the 3-times length
of a football field utilizing 4 locomotive sized tensioners and an abandonment
and recovery winch totaling over 8,000 HP of computer controlled and
coordinated AC Vector drives.
One of our systems successfully laid Z-Pipe 2B (60”ID/80”OD) from the Troll
Gas Fields off Bergen Norway over the Norwegian Trench to France. At
maximum depth of 450 meters my machines were holding up and stabilizing
over a mile of suspended pipe with a dry air weight of several million pounds.
System malfunction and dropping the pipe onto nearby high pressure lines
could sink the ship with hundreds of personnel on board. The actual
tensioning machines were still under construction and not available, so I
designed a computer model to simulate the mechanics and hydraulic drives of
the tensioners.
The pipe string catenary was modeled with variable ocean depth. A random
sea state generator along with forward platform velocity was provided to
drive the tensioner system modeling computer connected to the actual control
system. An HMI graphic interface was provided for operator controls and a
graphic display of wave height and pipe tension fluctuations resulting from
sea state and forward motion. The simulated system regulated pipe tension to
better than 1% and the tensioner/pipe system model proved to behave
exactly like the actual installed hardware on the pipe laying barge.
Also for HMD, pioneered the first application of a computer controlled
accelerometer based Active Heave Compensation system for stabilizing the
drill pipe in offshore drilling operations. This system uses Drawworks drives
totaling 6000 HP to stabilize the top of the drill string to less than 10 CM of
movement for a maximum 10 meter vertical platform displacement due to
swells. Older air spring technology was only 60% efficient. In 2000, this
technology along with advances in Global Positioning pioneered drilling in
depths of up to 18,000 feet of water. Deepwater Pathfinder, Frontier, and
Millennium were the first drill ships equipped with Active Heave Comp. The
Deepwater Horizon was not…

At Colorado Railcar Manufacturing LLC (CRM), I capitalized on my offshore
HMD pipe tensioner experience to control and coordinate multiple diesel
drives in self-propelled DMU passenger locomotives. Field service personnel
rated my traction systems as best in the industry for traction and
performance. The system utilized high performance redundant computers to
control diesel hydraulic drives and limit driven wheel slip to within a few RPM
of passive axle RPM. This burned moisture and contaminants off the rails
without liquefying the steel traction interface for maximum traction.
The CRM task required seamless integration of all electronics, electrical
systems, doors, braking, wheel slip/spin controls, propulsion systems,
operator controls, engines, and transmissions on the locomotives. A Trainline
Ethernet communication system was provided for monitoring and diagnostic
(MDS) capabilities between multiple Locomotives on the train. The MDS was
also extended to provide a remote monitoring and diagnostics capability for
monitoring and troubleshooting trains from a central office while the trains
were in operation on the tracks. The ability to remotely monitor and
troubleshoot the operation of trains from our offices in Colorado saved many
field trips to customer sites.
Projects included double decker heavy rail DMU train consists for SFRTA in
Miami Florida, sleek bullet nosed single deck heavy rail train consists for
TRIMET in Portland Oregon, and a self-powered scenic bi-level DMU for Alaska
Railroad (AKRR) – the Chugach Explorer.
Colorado Railcar’s double decker three-car consists in Miami carried up to
1,000 seated and standing passengers during peak rush-hour so safety was a
critical factor in system design. Multiple redundant systems were incorporated
with fail-down to manual modes of operation to prevent stranding trains and
passengers tracks in between stations.
At Aspen Ski Company, I am a PSIA certified Professional Ski Instructor and
have been studying the dynamics of skiing and biodynamics of the human
body for years. I am now applying my knowledge in Modern Physics and
Biodynamics to help improve skiing safety, and drastically streamline and
accelerate the learning process in skiing. The streamlined learning process
has proven to generate dramatic results in skiers of all ages and ability levels.
