Patent CA-2494337-C (CA)
Title: Systeme et procede d'annulation d'interference dans un calcul d'emplacement, a utiliser dans un systeme hertzien de localisation
Inventor: ANDERSON ROBERT J
IPC: H04W4/90
Filed: 2003-08-11
Granted: 2013-10-22
Abstract: Dans un système hertzien de localisation, la réception et la démodulation de signaux sont souvent réalisées sur de nombreux sites. Une collision peut se produire, par exemple dans un système TDMA, AMPS, GSM, GPRS, EDGE, CDMA, CDMA 2000, ou WCDMA, lorsqu'un signal d'intérêt (l'émission d'un émetteur mobile à localiser) et un signal d'interférence sont reçus en même temps et sur le même site. Dans le cas où une telle collision se produit, le signal d'interférence peut se trouver démodulé par un système récepteur, ou SCS, sur un autre site, et les données démodulées connues par le TLP (processeur de localisation TDOA). Cet élément interférant peut être reconstruit et soustrait des données brutes représentant la combinaison de signal constituée du signal d'intérêt et de l'élément interférant sur le site où la collision s'est produite. Cette technique permet un rejet important d'interférence (s'est à dire, environ 10 - 15 dB) avec peu de dégradation du signal d'intérêt.

Abstract: L'invention concerne un procédé permettant d'améliorer des commandes de codage vidéo par longueur de plage dans lequel toutes les commandes de compression nécessitant une valeur de pixel actuelle à comparer avec une valeur de pixel envoyée précédemment, afin de déterminer si une compression peut avoir lieu dans une plage plus longue, sont réglées de manière à alléger des conditions d'appariement exigeantes. A la place d'un appariement exact, un moteur de compression soustrait une valeur de pixel d'une autre et compare la valeur absolue du résultat à une valeur seuil. De cette manière, des longueurs de plage peuvent être allongées, aux fins de compression et le rendement de compression peut être accru.

Title: Method for hydrocracking of petroleum heavy oil
Inventor: OKUI TOSHIAKI
IPC: C10G47/02
Filed: 2007-02-26
Granted: 2010-06-15
Abstract: A method for hydrocracking petroleum heavy grade oil containing heavy metals in a slurry bed reactor with the help of an iron catalyst is provided. This method includes a step of selectively removing TI (toluene insolubles) by sedimentation solid-liquid separation from the liquid fluid arising from the reaction product. The procedure for separation causes no clogging in the underflow of the settling tank (sedimentation solid-liquid separator) and requires no large settling tank. The selective TI removal is accomplished by using a light solvent for solid-liquid separation which is a mixture composed of aromatic light solvent and self-supplied light solvent arising from the hydrocracking. The mixed solvent is used in an amount 2 to times the amount of the liquid fluid from which TI is to be selectively removed, and the sedimentation solid-liquid separator is run at 130-250°C.
