Dr. Steven R. Hofstein, an internationally known scientist with over 40 patents and numerous publications, gained initial prominence through inventions that include the Metal-Oxide-Silicon (MOS) Transistor IC - the technology that enables today's billion transistor chips, the Lithocon silicon storage tube, and the Liquid Crystal Display (LCD) Digital Watch. His long and successful career has been chronicled over the years by numerous publications that include the New York Times, Newsweek, Business Week, Electronic Engineering Times, Circuit News, U.S. Patent office, etc.

Several years ago he saw an opportunity to apply his knowledge and experience in both scientific and engineering fields towards building unique business applications utilizing Artificial Intelligence based 
   Expert System 
 technology.  The result is CognasysES, a  document processing software system able to replicate and automate the capabilities of highly trained human knowledge workers in almost any field.    

Dr. Hofstein received his PhD from Princeton University and is the recipient of a Franklin Institute Award, one of the oldest, most prestigious, and comprehensive science and technology awards programs in the world, and was elected as a Life Fellow of that institute for his pioneering work in MOS technology.

Spurring the Technical Revolution with the MOS Transistor
MOS Transistor

Late in 1962, two young engineers working at RCA's Research Laboratory and only a few years out of college, completed the development of the metal oxidize semiconductor (MOS) transistor nearly 50 years after the idea was first conceived by a German physicist. The MOS transistor came to be the fundamental building block of today's memory chips and microprocessors and for nearly 40 years, the MOS was the mainstay of the global chip industry and was used in virtually every electronic device and circuit.

When Dr. Hofstein first joined RCA, he was told about several project opportunities and received some politically wise advice on the MOS transistor project. The MOS project was a "hot potato" that had killed many careers since everyone who had tried it could not make it work; however, if he succeeded - he would be a hero. Hofstein accepted the MOS project.. and the rest is history.

Combining the Power of Liquid Crystal Display with the MOS

Pioneering the 1st Professional Conference in Las Vegas
Las Vegas While it is widely known how Dr. Hofstein's imaging and semiconductor inventions changed history, few may know that he also changed history, but in a much different fashion. Hofstein founded the Silicon Interface Specialist Conference and chose Las Vegas as the location. This conference, which took place in 1965, was the first-ever professional conference to be held in Las Vegas and once again.. the rest is history. (Yes, even scientists know how to have fun!)
Launching the Birth of Video Imaging with the Lithocon [Electronic] Tube

When Hofstein left RCA in 1968, he founded Princeton Electronics Products, Inc., and invented the Lithocon silicon storage tube, which quickly found many uses.

  • Supplying a low dosage portable x-ray system used by airports to inspect packages that may contain bombs,
  • Providing the first diagnostic quality images taken with ultrasound for medical diagnostics.
  • Storing and retrieving images of fingerprints for the FBI.
  • MarsLocating and accessing library microfilm publications.
  • "Frame-Snatching" television pictures - storing, altering and playing back single TV frames continuously over a standard TV set.
  • Recording pictures of Mars (7,300 images taken by Mariner 9 and displayed during Super Bowl Sunday so that all across America, people witnessed this great milestone in history!).
Modernizing the Computer Graphic Industry
System 850

After his success in the scientific research industry, Dr. Hofstein focused his efforts towards the computer industry by partnering with JRC, a Japanese organization, to build the first-ever computer with a graphical display. The Princeton System 850 Series' architecture, designed and built using the Lithocon storage tube, was the breakthrough in technology that is known as the foundation for the computer-graphic industry.

Transforming the Document-Driven Business Processes

Most recently, Dr. Hofstein has dedicated his knowledge and expertise in the imaging industry to create the first-ever Expert System application to solve the most complex document-driven business needs.

Expertise Knowledge

Founded in 1991, Cognasys LLC. developed a suite of business solutions, Cognasys ESŪ that can emulate the reasoning and behavior of human workers who have specialized knowledge and the training needed to solve a problem or clarify uncertainties. Expert Systems are comprised of highly-complex technical solutions historically used by the medical, scientific, engineering, and other similar industries.

Cognasys ES is unique in that it is the only application of its type that uses Expert System technology for processing of business transactions.
