When the initial flurry of activity died down I was asked and managed to solve grounding and other nagging problems in the analog circuits. Then I designed, built and tested two high-resolution CCD cameras for high-speed electronic imaging. I ended up with a complete analog "front end" which included an FIR filter for image enhancement and a fluorescent lamp document illumination system. The fluorescent lamps were driven by a servo-controlled switching power supply to insure lamp ignition and constant illumination regardless of ambient temperature or lamp aging.

Meanwhile, on my own, I had given much thought to the subject of "intelligence" in computers. Before the experts had begun to take (artificial) neural networks seriously, I wrote the basic patent for what was to become the neural engine used in the RayVan Artificial Cochlea.
