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 |

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 |

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 |

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 |
