Abstract: Abstract of the Invention Prior art radar systems do not adapt the transmitted signal to avoid the interference bands but only filter the unadaptive receiver signal to eliminate the interference with resulting loss in detectability and distortion that in turn causes loss in resolution and increased ambiguity. The present invention allows a radar system to operate in an  electromagnetic  environment  where  co-channel  narrow band  interference  is  present,  without  loss  of detectability,  resolution  and  ambiguity.    The  present invention system adapts the radar transmitted signal so that  its  spectral  energy  is  significant  only  in  the interference free portions of the radar channel.  It next adapts the receiver to detect this transmitted spectrum and then equalizes the  signal by means of  transversal equalizer coefficients to reduce distortions to the signal sidelobes.

Abstract: ABSTRACT OF THE DISCLOSURE MASTER ELECTRICAL LOAD CONTROL SYSTEM    A system controls power to multiple a.c. lighting loads from both a central location and from individual controls that are located near the loads. The system includes individual wallbox dimmers that include enabling switches, a master control, and isolation means to accept input signals from the raster control and to provide output signals to the dimmers.   In a preferred embodiment, a dimmer also provides to the master control a signal that indicates the power being provided to the load that the dimmer controls. Preferably, the individual controls provide linear slide dimming, in which the power provided to a load is determined by the slider position.  The system permits simplified installation and replacement of system components.   Another system of the invention controls electrical power to multiple loads from both a central location and from local three-way controls.   In one embodiment, the system includes means for sensing the power to each load.  That sensing capability, in turn, permits the master to set all loads to the same power level, simultaneously, regardless of their original level.  The local controls may be standard three-way dimmers or switches.

Abstract: A safety device for the roll space within a calender or other roll machine is disclosed. The rolls when rotating, excite oscillations in the beam at the resonant frequency of the beam. This can occur during start-up or during normal operation. The safety device of the present invention comprises a beam and additional mass that is oscillatorily suspended from the beam in order to reduce the amplitude of the beam oscillations at the beam resonant frequency. In addition, a damping element between additional mass and the beam is used to reduce any undesired oscillations due to newly created resonant frequencies introduced into the system.

Abstract: This method relates to the compression of information contained in filled-in forms (O) by separate handling of the corresponding empty forms (CP) and of the information written into them (VP).  Samples of the empty forms are prescanned,  the data obtained digitized and stored in a computer memory to create a forms library. The original, filled-in form (O) to be compressed is then scanned, the data obtained digitized and the retrieved representation of the empty form (CP) is then subtracted, the difference being  the  digital  representation  of  the  filled-in information  (VP),   which  may  now  be  compressed  by conventional  methods  or,  preferably,  by  an  adaptive compression scheme using at least two compression ratios depending on the relative content of black pixels in the data to be compressed.

Title: Intra-cell call hand-over in radio communication systems with dynamic channel allocation
Inventor: PLETT GREGORY LOREN
IPC: H04W36/06
Filed: 1990-12-14
Granted: 1998-07-07
Abstract: The intra-cell call hand-over technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining a standby radio traffic channel upon which to hand over a call.  Communication between the base station and subscriber terminal is carried out on an inband or associated signalling channel for the selection of the standby traffic channel.  The standby radio channel is the channel, which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal.  The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service.  This subset is comprised of those channels having little interference as measured by the base station. The call hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.
