Latest Patents

One of his significant patents is titled "Cable length detection and signal compensation apparatus and method for a keyboard video mouse switch and extender." This invention describes an apparatus in a video signal transmission system that measures cable length and compensates for cable loss. The system compresses multiple pilot signals of different frequencies into one of the three color signals during vertical sync periods. The vertical and horizontal sync signals are compressed into the other two color signals. The video signal is transmitted over a cable with at least three pairs of wires, with each color signal transmitted by one pair. A pilot signal converting circuit obtains the levels of the pilot signals transmitted by the cable. A compensation control circuit averages the levels of the multiple pilot signals over several vertical sync periods and generates compensation control signals based on the average level. These signals are then used to perform video signal compensation.
