Title: Pwm converters for three phase ac power control and ac to dc conversion, and special purpose devices using the same
Inventor: VENKATARAMANAN GIRI
IPC: H02M7/217
Filed: 1995-03-17
Abstract: PWM converters provide buck, boost, buck-boost, flyback, and Cuk configurations for three phase AC-AC power control. In an AC-DC embodiment, only a single power conversion circuit is used in a configuration including a pair of series connected gate turn off devices (transistors and diodes) which are oppositely poled and oppositely timed, are connected directly to an AC  input source, and provide an output to a high frequency isolating transformer.  The transformer provides an output to a rectifier (diodes), which thus provides the DC output (capacitor). Special purpose, custom power, applications of the converters include alternatives to Uninterruptable Power Supplies and eliminate the need for local storage. By controlling duty ratio of the converters a simple replacement is provided for a tap-changing transformer. By providing a plurality of different duty ratios to plural converters, a dynamic cluster integrates a plurality of three-phase buses and controls the power drawn from each bus.

Title: Document registration apparatus with improved document drive capability
Inventor: LYGA THOMAS M
IPC: B65H9/10
Filed: 1997-11-06
Abstract: A document registration apparatus for use with a conveying device for transporting a document along a path from an upstream direction to a downstream direction through a document registration position includes an urge roller positioned adjacent to the path, the urge roller being moveable between a first position contacting the document and a second position out of contact with the document. The urge roller is biased toward the conveying device. A  registration stop is positioned adjacent to the urge roller and the path, the registration stop being moveable between a first position where it blocks transport of the document along the path and a second position away from the path where it does not block transport of the document along the path. At times when the urge roller is in its first position and the registration stop is in its first position the urge roller is biased against the document by a first force thereby urging the document against the conveying device due to the first force so that the document is moved to, aligned against, and stopped by the registration stop at the document registration position. At times when the urge roller is in its first position and the registration stop is in its second position the urge roller is biased against the document by a second force such that the document is urged against the conveying device by the first and second forces so that it is moved from the document registration position in a downstream direction from the registration stop.

Abstract: The present invention provides a system for a method, system (300), subscriber unit (320, 330), and base/headend unit (310) for a bandwidth efficient multiple user digital communication system (300) that facilitates multiple user reverse link communication using overlapped transmit signal spectra of at least two overlap bandwidth subscriber units (320, 330). Overlap bandwidth subscriber units (320, 330) receive a forward link signal, each deriving a frequency reference from the forward link signal and a symbol timing reference from the forward link signal, and transmitting a reverse link signal to the base/headend unit (310) that receives a composite reverse link signal of the reverse link signals. Each reverse link signal includes at least one modulated data carrier with distinct carrier frequencies. Each transmitted reverse link signal has a symbol timing responsive to the symbol timing reference, and the frequency spectra of the reverse link signals overlap using overlapped transmit signal spectra of at least two overlap bandwidth subscriber units (320, 330).
