Inventor: ROWITCH DOUGLAS N
IPC: H04B7/26
Filed: 2001-11-14
Abstract: L'invention porte sur des techniques permettant de détecter si un terminal distant d'un réseau sans fil de communication est ou non à l'intérieur de l'aire de couverture d'un répéteur se basant sur: (1) la liste des stations de base de l'aire de couverture du répéteur susceptibles d'être captées; (2) l'environnement caractéristique du répéteur; et (3) les retards de propagation d'une émission reçue par le terminal distant. On peut également prendre en compte et/ou compenser les autres ambiguïtés résultant du fait de se trouver dans l'aire de couverture du répéteur: (1) en écartant les mesures de temps des stations de base répétées; (2) en affinant le traitement d'estimation des positions en tenant compte des ambiguïtés supplémentaires dues au répéteur; en calculant une série d'estimations de position se basant sur plusieurs émissions reçues d'une même station de base d'origine, et en sélectionnant la meilleure estimation; et en calculant une série d'estimations de position basées sur plusieurs émissions de plusieurs stations de base d'origine, puis en sélectionnant la meilleure estimation.

Patent CA-2441839-A1 (CA)
Title: Ladle refining of steel
Inventor: GROSS CLAY A
IPC: C21C5/34
Filed: 2002-04-02
Abstract: A steel charge and slag forming material is heated in a ladle to form molten steel covered by a slag containing silicon, manganese and calcium oxides. The steel is stirred by injection of an inert gas such as argon or nitrogen to cause silicon/manganese deoxidation and desulphurization to produce a silicon/manganese killed molten steel. Stirring of the molten steel by the inert gas injection while in contact with slag high in calcium oxide generates low free oxygen levels in the steel and desulphurization to sulphur levels below 0.009%. The slag may subsequently be thickened by lime addition to prevent reversion of sulphur back into the steel and oxygen may be injected into the steel to increase its free oxygen content to produce a steel that is readily castable in a twin roll caster.

Title: Method for controlling a wind energy plant
Inventor: WOBBEN ALOYS
IPC: F03D9/25
Filed: 2002-04-12
Abstract: The present invention concerns a method of controlling a wind power installation and a wind power installation in particular for carrying out the method.      Wind power installations have been generally known for a long time and in recent times are increasingly used as environmentally friendly energy generators.      In that respect it is in the very nature of things that such installations are exposed to the influences of the weather. One of the problems which is of great significance in wind power installations is moisture as wind power installations with their electrical systems must be substantially protected therefrom.      Therefore, the object of the present invention is to eliminate that risk which occurs due to the moisture.      A method of controlling a wind power installation characterised by detecting the temperature of the generator and the temperature of the air in the surroundings of the wind power installation, ascertaining the temperature difference, and heating the generator if the temperature of the generator is below the temperature of the ambient air.

Patent CA-2447346-A1 (CA)
Inventor: EASTON DAVID JOSEPH
IPC: F16H59/02
Filed: 2003-10-30
Abstract: A control lever assembly for a vehicle transmission includes a housing which supports a guide plate having a slot and a recess formed in a central portion of the slot. A carrier member is pivotally coupled to the housing about a pivot pin.  A lever has a shaft which is supported by the carrier and which is rotatable and axially movable relative to the carrier. The lever has a knob which is mounted on an end of the shaft and which is received by the slot. A spring is coupled between the shaft and the carrier and is biased to rotate the knob and to urge the lever towards the pivot pin. When the knob is in the slot and outside of the recess, the slot walls prevent rotation of the knob and maintain the lever in a first rotary orientation. When the knob is moved into the recess, the spring is automatically able to rotate the knob and lever into a second rotary orientation. When the knob is in the second orientation, the recess walls are engagable with the knob to prevent the lever from being pivoted about the pivot pin. The housing includes a detent member which engages detent rollers mounted on the carrier to releasably hold the lever in selected positions in the slot. The knob may be manually moved axially over an abutment formed by a wall of the recess and rotated into a third rotary orientation.

Title: Apparatus and a method for pulse detection and characterization
Inventor: ALLEN JOHN B
IPC: G01J1/00
Filed: 2002-08-22
Abstract: An optical/analog/digital pulse detector receives an input signal and drives a Bragg cell illuminated by a collimated light beam. The Bragg cell spatially modulates the collimated light beam and upon exiting the Bragg cell is imaged by lenses of an optics network to the plane to an opaque plate. A binary optical plate replicates the image of the Bragg cell on the opaque plate. The opaque plate contains slits of various lengths located where the images of the Bragg cell are replicated. To obtain the power spectrum of each of the images on the opaque plate an anamorphic lens is positioned in the path of light passing through the opaque plate. Light passing through the anamorphic lens is sensed by a detector array having outputs coupled to a focal plane processor that processes the analog outputs from the detector array into initial tuning commands for detection and characterization of pulses in the input signal.
