Title: A hybrid equalizer arrangement for use in data communications equipment
Inventor: GADOT SHLOMO
IPC: H04B3/14
Filed: 1995-09-13
Abstract: A hybrid type of decision feedback equalizer (DFE) structure that approaches optimal DFE performance is described. The hybrid DFE includes both an intersymbol interference DFE (ISI-DFE) and a noise predictive DFE (NP-DFE). The hybrid DFE structure is designed so that one form of tap values dominates over the other. This allows only the dominate tap values to be used by the transmitter during precoding and reduces the transmitter complexity. In particular, a hybrid DFE is designed so that the I(z) coefficient values dominate over the N(z) coefficient values, where the notation I(z) and N(z), as known in the art, represent the resulting coefficient values after adaptation of the ISI-DFE and the NP-DFE, respectively. A respective Tomlinson precoding scheme in the transmitter uses only the I(z) values. Since only the I(z) values are used in the precoder of the transmitter, the NP-DFE of the receiver is kept active during the communications phase. Conveniently, the continued use of the NP-DFE in the receiver allows the receiver to track small changes in the channel.

Patent CA-2166638-A1 (CA)
Inventor: MALLIKARJUN RAMESH
IPC: C08F6/00
Filed: 1996-01-05
Abstract: A thermoplastic resin such as a styrene/maleic anhydride copolymer is treated to remove volatile impurities such as unreacted styrene by admixing with a chemical blowing agent and extruding under a vacuum. The chemical blowing agent is converted into an inert gas such as carbon dioxide during extrusion; the gas evolved is removed, together with the volatile impurities, through one or more vents in the extruder. The use of a chemical blowing agent, rather than the inert gas itself, permits the facile distribution of the CO2 stripping agent throughout the molten thermoplastic resin using commonly available extruders without the need for elaborate gas injection means.

Title: Mechanism for connecting ornamental parts of wrist watch
Inventor: YAMAMOTO AKIO
IPC: A44C5/18
Filed: 1996-02-16
Abstract: A mechanism for connecting ornamental parts of wrist watches that permits easy assembly and disassembly of the parts without using special tools and without detracting from the appearance of the wrist watches.  The mechanism includes a pin and a sleeve for receiving and retaining the pin.  The pin has end regions of a first diameter and at least one region located between the ends of a second, smaller diameter.  The sleeve may be figure-eight shaped or obround and includes two interconnected bores of different diameter.  A first larger-diameter bore is sized to loosely accommodate the larger-diameter end regions of the pin, while the second smaller-diameter bore is sized to accommodate the smaller-diameter region of the pin.  In use the sleeve is inserted in an opening shaped to receive it in one part to be assembled and the parts are aligned.  The pin is then inserted through both parts and the sleeve.  Pulling in opposite directions on the parts forces the smaller-diameter region of the pin into the smaller-diameter bore in the sleeve where it is retained by inwardly protruding ribs between the two bores of the sleeve, or by resilient tension created by deformation of the sleeve.  With the pin thus securely held in place, the two parts are firmly connected.

Title: Brake device
Inventor: ASANO YOSHIO
IPC: F16D65/28
Filed: 1996-03-01
Abstract: A brake device equipped with an actuator having a power-transmission member generating a pushing force by receiving a drive force so as to advance. A pressure-detection device is provided for detecting the reaction pressure being applied to the power-transmission member and a clearance controller is provided for making the power-transmission member perform a return stroke. A brake shoe is attached to the power-transmission member and generates a braking force on the wheel tread surface.  Such clearance controller is provided with a stroke memory unit which detects when the pressure signal from the pressure-detection device has reached a reference value when the pushing force of the power-transmission member is output and memorizes the stroke position of the power-transmission member as the reference stroke position.  A computational processor determines the return stroke position by which the power-transmission member is separated from the wheel tread surface and the clearance stroke fraction established in advance using the reference stroke position, when the pushing force is released.

Title: Apparatus for processing mixed YUV and color palettized video signals
Inventor: BUTLER DONALD S
IPC: H04N7/173
Filed: 1996-06-24
Abstract: Apparatus processes mixed YUV and color palettized video signals, where "Y" of YUV is the luminance signal and "U" and "V" are the color difference signals, B-Y and R-Y respectively, for display on an interlaced NTSC or PAL television receiver by storing first and second fields of one or more sprites in a graphic memory. The sprites are stored as YUV or color palettized data and each sprite is given a priority. A higher priority sprite overwrites pixel data of sprites of a lower priority when sprites overlap. First and second adjacent horizontal lines of pixel data in the first and second fields, respectively, are concurrently stored in respective first and second double buffers of a pixel assembly buffer during each line period. A delay buffer and the first and second double buffers generate first, second, and third adjacent horizontal lines, respectively, of pixel data at the output of the pixel assembly buffer while third and fourth adjacent horizontal lines of pixel data are inputted to the first and second double buffers. A convolving means receives the first, second, and third output signals from the pixel assembly buffer and generates therefrom an output signal providing a weighted average for a central pixel of a predetermined matrix of pixel data for transmission to the television receiver when a sprite is included in a pixel area of the display of the television receiver. A live video signal is transmitted to the display of the television receiver when no sprite is included in a pixel area of the display of the television receiver.

Filed: 1995-09-25
Abstract: A method (100), a device (300), and a radio (500) are described for compensating for modulator frequency drift while allowing for data transmission in a half-duplex frequency modulated communication system. An adjustment is made to a premodulation signal in such a way that when it is passed through a frequency modulator to provide a transmitter excitation signal, frequency drift is corrected. Subsequent to determining a training command, the transmitter excitation signal passes through a switch to a demodulator. The demodulator output is averaged and used in the adjustment.

Title: In situ soil and/or residue remediation system and process using multi-level midspacing measurement
Inventor: PELLETIER MARC-ANTOINE
IPC: B09C1/06
Filed: 1995-06-28
Abstract: A system and process for in situ remediation of contaminated soils and/or residues is disclosed. These system and process take advantage of a radial flow irrigating/draining system and a multi-level sensor arrangement located at midspacing between parallel, horizontal conduit lines to create an environment propitious to the action of decontaminating agents (plants, microorganisms, salts, acids, bases, buffers, enzymes, substrates, surfactants, etc.). For example, a water-saturated zone is created and the level of water containing decontaminating agents is raised, maintained and/or lowered; the water-saturated zone encourages desorption or solubilization of soluble contaminants through adjustment and control of at least some parameters of reaction (time, temperature, pH, oxygenation, etc.) The system and process are easily adaptable for many classes of contaminants, including volatile compounds and light non-aqueous phase liquids, by further installing supplementary sets of conduit lines and pumps at adequate levels.      Remediation of a site may be conducted by alternating gaseous and liquid modes to optimize the conditions of reaction.
