Karl Fant, Founder and President Karl Fant, Theseus Research Cofounder and President

In a sixteen-year career at Honeywell Systems and Research Center, Mr. Fant created and directed key programs and contracts that led the Signal and Image Processing group to preeminence in the nation in real-time automatic target recognition. Other programs included medical imaging, industrial inspection and image generation. Mr. Fant is the co-inventor of Computer Generated Synthesized Imagery (CGSI), which generates photo-realistic scenes in real-time from libraries of photographic images, by warping each into place and blending them together. In 1982 Mr. Fant received the H. W. Sweatt award, Honeywell's highest award for technical achievement, for his invention of a unique digital-image warping algorithm developed for CGSI.

In October, 1990 Theseus Research Inc. was founded to provide consulting in the design and implementation of real-time image processing systems and to pursue applications of ongoing research into the theory of computers. The primary accomplishment of Mr. Fants consulting activity was the implementation of the prototype L-VIS system for Princeton Video Inc. This is the system that puts the yellow first-down line on the football field, and that inserted the virtual advertisements behind the batter in the 2001 World Series.

In January, 1996 Theseus Logic was spun out of Theseus Research to commercialize NULL Convention Logic (NCL), a direct result of Mr. Fants research in the theory of computers. NCL is an expressively complete logic that is ideal for designing and implementing clockless, logically determined, digital electronic circuits and systems. Theseus Logic continues to commercially develop NCL.

Mr. Fant has returned to Theseus Research to continue developing and commercializing new technologies .
