Title: Method for supporting a discontinuous transmission mode in a base station in a mobile communication system
Inventor: CHANG YONG
IPC: H04J13/00
Filed: 2000-05-12
Granted: 2005-02-22
Abstract: Disclosed is a method for transmitting a signal from a base station transceiver system (BTS) to a base station controller (BSC) when there is no data transmitted from a mobile station while in discontinuous transmission (DTX) mode, in a mobile communication system. The mobile communication system includes a mobile station for transmitting and receiving data in a predetermined period, a base station transceiver system and a base station controller for controlling the base station transceiver system. Upon detection of the discontinuous transmission mode, it is determined what type of frame was last transmitted from the mobile station, and the present power control information is set according to the type of frame. If it is a null frame, the base station transceiver system sets previous power control information that the base station transceiver system has used for power control of the mobile station before detection of discontinuous transmission mode, to present power control information.       There-after, the base station transceiver system transmits a reverse message including the present power control information to the base station controller over a dedicated control channel. If there is data being transmitted between the mobile station and the base station transceiver system at the time where the discontinuous transmission mode is detected, the previous power control information is set to the present power control information.

Title: High speed evaporator defrost system
Inventor: DUBE SERGE
IPC: F25D21/06
Filed: 2001-06-12
Granted: 2009-08-11
Abstract: A high-speed evaporator defrost system is described. It comprises a defrost conduit circuit having valves for directing hot high pressure refrigerant gas from a discharge line of a compressor and through a refrigeration coil of an evaporator of a refrigeration system during a defrost cycle thereof, and back to a suction header of the compressor through a reservoir of the refrigeration system to remove any liquid refrigerant contained in the refrigerant gas prior to returning to the suction header. The reservoir has an internal pressure which is generally at the same pressure as that of a suction header of the compressor thereby creating a pressure differential across the refrigeration coil sufficient to accelerate the hot high pressure refrigerant gas in the discharge line through the refrigeration coil of the evaporator to quickly defrost the refrigeration coil. The reservoir is repressurized after the defrost cycle for using the reservoir in a refrigeration cycle.

Abstract: Cette dispersion aqueuse pour répulsifs eau et huile se révèle remarquable en matière de répulsivité eau et huile et de répulsivité à l'encontre des gouttes d'eau. Elle fait montre d'une remarquable stabilité à la dispersion même si le bain de traitement comporte également une substance chimique ou si une impureté y est présente. Le procédé consiste à émulsionner sous pression une composition de matériau de départ comprenant un ou plusieurs monomères comportant comme ingrédient essentiel un (méth)acrylate possédant un groupe polyfluoroalkyle, un tensioactif non fluoré ne contenant pas de groupes aromatiques, de l'eau et un solvant dont la viscosité à 25  DEG C est égale ou supérieure à 3 cP. Ces monomères émulsionnés sont ensuite polymérisés. Grâce à ce procédé, on obtient la dispersion aqueuse selon l'invention.

Abstract: The deadbolt thumbturn assembly of the present invention includes a thumbturn including a thumbturn extension, which is inserted through a bushing collar and rose bearing, then secured with a retaining ring such that the thumbturn extension is able to rotate within the bushing collar. The threaded bushing collar is then inserted through the aperture of the deadbolt rose and secured with a retaining ring forming a deadbolt thumbturn assembly such that the threaded bushing collar is able to rotate with respect to the deadbolt rose. The thumbturn assembly is then attached to the inside housing of a single cylinder deadbolt lock by fastening the bushing collar to the threaded boss of the inside housing such that the extension of the deadbolt actuator is inserted into a receptacle of the thumbturn. This design of the thumbturn assembly allows for attachment to the inside housing while still allowing rotation of the thumbturn to extend or retract the deadbolt. The novel attachment design allows the thumbturn to be manufactured from forged materials, adds to the aesthetic appeal, provides concealment for mounting screws, and is easily installed.

Filed: 2002-04-23
Granted: 2005-09-20
Abstract: A control system for a harvester or similar implement includes a supervisory controller, a set of low-level controllers and a neuro-fuzzy inference system.  The supervisory controller employs human expert knowledge and fuzzy logic. The controller monitors the quality of the harvesting process, such as gain loss, dockage, grain damage and the like. Based on the measurements, setpoints for all critical functional elements of the implement are determined. The neuro-fuzzy inference system determines machine settings according to operating conditions and learns from harvester experience. The parameters of the neruo-fuzzy inference system are stored in on-board memory. The neuro-fuzzy system can be used for harvester set-up and as one of the knowledge sources for repeated adjustments during the harvest.

Title: Rotating arc fault-current interrupter
Inventor: EVANS DANIEL J
IPC: H01H73/18
Filed: 2002-10-17
Granted: 2011-08-30
Abstract: A rotating arc fault-current interrupter, also known as an arc spinner interrupter, is provided that establishes an easily visible open gap via a movable blade member having a first portion for engaging a stationary main contact and a second portion formed by an arcing electrode for engaging an auxiliary contact associated with an arc spinner assembly. The geometry, orientation and placement of the auxiliary contact is such that during opening of the movable blade member, the arcing electrode remains engaged with the auxiliary contact after the blade member and the stationary main contact are separated from each other whereby current is transferred through the auxiliary contact into the arc spinner assembly, i.e. the current is commutated into the arc spinner assembly. Thus, the current in the arc spinner creates a magnetic field to cause the arcing current to rotate rapidly so as to extinguish the arc as the arcing electrode separates from the auxiliary contact and moves to the opened position whereby a visible open gap is established that is easily visible without any obstructions from a range of viewing angles or orientations.

Patent CA-2424857-C (CA)
Inventor: MONTREUIL MICHEL
IPC: H02H9/00
Filed: 2003-04-08
Granted: 2009-09-08
Abstract: The attenuation of the stray current impulse limits the capacitive leakage. The value of the inductance, coupled to the parasitic capacitance of the charge, creates a reactive filter effect. Since the effect is reactive, the impulse energy is not absorbed. The energy is therefore redistributed in time, but since the intensity of the tension is greatly diminished, the coupling through the capacitances is diminished. The apparatus comprises a core which includes 1, 2, 3 or 4 coils. The apparatus is typically a high quality reactance which includes a low reactive value in opposition of the line current (residual mode) and a high reactive value for the circulation of the parallel current (common mode).
