RE31545 Feed-forward amplifier March 27, 1984
A high-precision amplifier employs a feed-forward technique to provide a first order correction of amplifier distortion. A second amplifier is utilized to sense the base-to-emitter distortion of a main amplifier and develop an error output which is injected into an output node to provide
RE31238 Electrographic copier with one-piece belt and styli May 10, 1983
Electrographic paper is fed over a segmented platen where its dielectric surface receives image defining electrostatic charges deposited by styli bearing directly and successively upon it. The styli are integral to an endless belt moving laterally to the surface. Voltage pulses correspon
RE31114 Electrical connector December 28, 1982
This disclosure describes an electrical connector for joining microcircuit or microcircuit modules, such as leadless integrated or hybrid circuit carriers to utilization means, such as printed or etched circuit boards or similar means. The electrical contacts through which the microcircu
RE30094 Optoelectronic switch September 11, 1979
A light actuated switch apparatus is described in which no movable switch contacts are employed. The switch uses a light source and shutter to activate an array of light sensitive devices to generate a binary code that provides the switching function. One embodiment of the switch app
RE29510 High efficiency switching drive for a resonate power transformer January 3, 1978
A high efficiency switching drive for a resonate power transformer having the ability to maintain a constant output voltage over a wide range of source voltage variation while maintaining good power conversion efficiency is provided. A transistorized class-C oscillator has means to s
RE29018 Continuously variable resistance attenuator using lossy transmission line and having constant si October 26, 1976
A continuously variable resistance attenuator is described in which the signal conductor of a distortionless lossy transmission line is employed as an attenuation resistance uniformly distributed along such line, and the connection of an output contact is moved along such signal conducto
RE28773 Charge image storage method and apparatus April 13, 1976
The information stored on the dielectric target of a bistable storage tube is read out nondestructively employing a pulsed electron beam. The electron beam is turned on for a period having a duration less than necessary to change a given area of the target from one stable stored pote
H2184 Wide dynamic range vector data raster display March 6, 2007
A wide dynamic range vector data raster display of a waveform image is obtained by using a small matrix of pixels from a source frame buffer containing waveform image data to calculate a value for each pixel on a target display. Any of several algorithms may be used for this transform
