Metric Systems Corp., Fort Walton Beach, Fla.,         1962 – 1966
            Vice President and Chief Engineer:   Directed all engineering activities,
            Developed Metric’s radar system under a Canadian contract for use at
            Fort Churchill to track high altitude rockets used for upper atmosphere studies. 
            Metric Systems Corp. was founded in 1962 by W. Gamel and myself .  
Raytheon Corporation, Wayland MA,  1967 --  1991  Principal Engineer
            Directed development of a “backtracking” radar which, within seconds of a        
            launch of enemy rocket or mortar fire pinpoints the location of the source. 
            Worked on Patriot Radar System.

AUTOSTEREOSCOPIC DISPLAY SYSTEM
   US Patent no. 8587641 issued to Alexander Roth, filed dec. 8, 2011
         PROJECT CURRENTLY IN PROGRESS  (Dec. 2017)
For details, see article in Stereo World magazine (May/June 2014) at:

                                           AQRProducts.com

At the present time, plans are in place to construct a small demonstration model, equivalent to a 12 inch TV, to prove the dynamic backlight display concept described in the patent.

          THE SMART ALEX PROJECT                (Pixtures below by Shari)


                                           Teaching computer                     (about 1980 – 1990)
The outstanding feature of the “Teaching Computer”  was the use of a real human voice with interactivity plus a comprehensive list of  reading topics.  The “real voice” feature was due to some tricky programming and cassette tape preparation which made it seem that the voice comments were appropriately responding to the user’s keyboard inputs.

METRIC SYSTEMS CORPORATION,   Fort Walton Beach, Fla.

FORT CHURCHILL, Manitoba, Canada

As chief engineer and VP of Metric Systems, I spent the 1965/66 winter at Fort Churchill, Manitoba, Canada running tests, on my project, on our modified SCR584 RADAR which was designed for tracking rockets to be launched there for upper atmospheric research

              Metric Systems Corp. was founded in 1962 by Wendell Gamel and myself .  

RAYTHEON CORPORATION

Raytheon Corporation, Wayland MA,  1967 --  1991  Principal Engineer
            Directed development of a “backtracking” radar which, within seconds of a        
            launch of enemy rocket or mortar fire pinpoints the location of the source. 
            Worked on Patriot Radar System.
            Developed simulation software for predicting radar performance.


MOTOROLA    After retiring in 1992 I was a consultant to Motorola in Phoenix for a one year study and design of the cells for the Iridium world wide satellite cell phone network.  I spent several weeks in Phoenix on this plus the rest of my time at home completing this project.  Once again, it involved computer modeling of the “cells” for a world-wide telephone system ---  the Iridium global telephone.  If you’re ever at some distant isolated place on our planet, dependent on you Iridium phone,  you may be establishing contact thanks to me.      


BOSTON UNIVERSITY – QUANTUM THEORY ANIMATIONS More recently, for 2 or 3 years after 2000, I worked with Prof. Sasha Sergienko, at the Photonics Center.  The project was to create video animations to clarify concepts in quantum theory.  I asked Steve Miller to join me to get the benefit of the science information this would provide.  Sergienko would (privately) lecture us on a particular leading edge experiment and explain the theory.  I would then work out how to produce a video to explain the matter.  I created about 40 minutes of educational  video animations which are visualizations and explanations of leading edge experiments in quantum theory.  I have links elsewhere in this document.

 OPTICAL WALKING AID FOR THE BLIND

A device such as this might be considered too crude an approach to guide a blind person, but, on the other hand, I know of nothing else that can do that that’s come into common usage.  Just as a cane lets the user know when the tip touches the ground, this device does the same with the tip of a light beam.



This idea was tested on a small scale at home.    It had the transmitter, transponder and a readout.  The transponder was moved around the house on the same wheeled teacart.  The readout actually kept track of the movements of the cart
