Louis D Silverstein, Robert W Monty: Four color repetitive sequence matrix array for flat panel displays. Honeywell, Seymour Levine, Albin Medved, Roger W Jensen, January 24, 1989: US04800375 (201 worldwide citation)

A four color repetitive sequence matrix array for flat panel displays is formed by establishing a repetitive sequence with pixels of four different colors arranged in the rows of the matrix. The sequence commences with a different color in each row, thereby establishing a second repetitive sequence ...

Martin Kanner: Anti-ripple circuit. Seymour Levine, December 1, 1987: US04710861 (142 worldwide citation)

A ripple reducing circuit wherein ripple voltages across the output terminals of a voltage source are coupled through a ripple sensing circuit to an amplifier. The sensed ripple is amplified and phase reversed to provide signals in phase opposition to the ripple signals. These phase opposition signa ...
