Johnny A Cornett, James D Corbett: Touchscreen control panel with sliding touch control. Sperry Marine, Seymour Levine, Albert B Cooper, October 1, 1991: US05053758 (264 worldwide citation)

Touchscreen control panel apparatus that highlights a control key to which the operator slides touch and actuates the associated control function upon touch release from the highlighted key. Highlighting is deleted from a key when operator slides touch therefrom without releasing touch. Parameter va ...

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 ...

Peter E Jacobson: Ball coupled compound traction drive. Honeywell, Seymour Levine, Albin Medved, May 17, 1988: US04744261 (142 worldwide citation)

A variable ratio traction drive employing a set of geometrically skewed axis drive balls mounted in an input carrier and captured between a split outer ring. An alteration of the axis skew angle of the balls causes a turns ratio change in the traction drive.

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 ...

Harry M Cronson, Basrur R Rao, Gerald F Ross: Shielded surface wave transmission line. Sperry Corporation, Howard P Terry, Seymour Levine, February 12, 1980: US04188595 (134 worldwide citation)

A continuous, self-supporting microwave transmission line along which ultra short pulses of microwave signals may propagate over distances of several hundred feet with minimum pulse distortion and signal attenuation. Propagation along the line is accomplished by an electromagnetic field thereabout t ...

David W Gerdt: Variable ratio fiber optic coupler optical signal processing element. Sperry Marine, Seymour Levine, Albert B Cooper, August 4, 1992: US05136669 (130 worldwide citation)

The coupler includes a waist region formed by merging and fusing a plurality of optical fibers with the waist region encapsulated in photorefractive encapsulating material. The index of refraction of the encapsulating material is modulated by applying illumination thereto, so as to vary the coupler ...

John R Kendig, William R Hibble, James A Kiedrowski: Magnetic isolating and pointing gimbal apparatus. Honeywell, Seymour Levine, Albin Medved, February 7, 1989: US04803413 (83 worldwide citation)

A magnetic isolation and pointing gimbal apparatus provides support functions and multidegree of freedom pointing capability and simultaneous six degree of freedom bi-directional disturbance isolation. This is accomplished by integrating the support, isolation and pointing functions within one conti ...

Gerald F Ross: Apparatus and method for sensing a liquid with a single wire transmission line. Sperry Rand Corporation, Howard P Terry, Seymour Levine, November 30, 1976: US03995212 (63 worldwide citation)

A method and apparatus for measuring the level and dielectric constant of a liquid which includes a device for generating a subnanosecond baseband pulse that propagates through a transition device to a single wire transmission line that extends through an air filled region into the liquid. A discont ...

Donald H McMahon: Electro optic switch. Sperry Corporation, Howard P Terry, Seymour Levine, July 24, 1984: US04461543 (61 worldwide citation)

An optical switch utilizes a birefringent device to cause orthogonally polarized components of an arbitrarily polarized incident light beam to propagate along separate paths. A polarization rotator is positioned in one path to rotate the polarization of the light beam propagating therealong to that ...
