Title: Fuel cell oxygen removal and pre-conditioning system
Inventor: ADCOCK PAUL LEONARD
IPC: B60R9/04
Filed: 2003-01-15
Abstract: A fuel cell having an anode, a cathode and an ion exchange membrane is supplied by hydrogen fuel through an anode fuel delivery conduit. A recirculation loop is provided to recycle gases in the fuel delivery conduit to a mixing point where a controlled flow rate of fuel is supplied and mixed therewith. Any oxidant species remaining in the fuel delivery conduit are thereby combusted in a controlled manner to avoid damage to the fuel cell membrane-electrode assembly. Small quantities of oxidant may be deliberately introduced into the fuel delivery conduit to generate water vapour and heat to pre-condition the fuel delivered to the anode. Such preconditioning assists in hydration control of the membrane, and temperature control of the membrane- electrode assembly for optimum fuel cell performance.

Title: Analyse spectroscopique et spectrometrique de melanges biologiques complexes assistee par des phases solides
Inventor: THIES SASCHA
IPC: G01N33/68
Filed: 2003-05-09
Abstract: L'objectif de la présente invention est de concevoir un procédé d'analyse de mélanges peptidiques complexes, au cours duquel le nombre de composants à analyser est significativement réduit et seule une faible quantité d'informations est perdue. A cet effet, les fragments peptidiques sont soumis à une sélection ciblée faisant appel à des réactions de couplage et de découplage sur un support solide ainsi qu'à une fragmentation. Différents modes de réalisation de cette invention sont exposés. Le premier mode de réalisation est fondé sur la propriété avantageuse qu'ont les peptides N-terminaux couplés de se libérer sélectivement du matériau de support lorsque du pDITC est utilisé en tant que lieur, alors que des peptides couplés par l'intermédiaire de chaînes aminoacides à fonctionnalité NH¿2? ne sont pas libérés. Le deuxième mode de réalisation fait appel au blocage des N-terminaux de peptides qui sont ultérieurement soumis à une division. Ces peptides sont ensuite couplés avec le support solide, et seuls les peptides présentant un N-terminal libre sont immobilisés, tandis que les peptides dont le N-terminal est bloqué peuvent être isolés au moyen d'une étape de lavage. Le procédé comprend éventuellement une étape consistant à marquer les peptides. Le mélange peut ensuite être analysé au moyen d'une spectrométrie de masse ou d'une spectroscopie par fluorescence. Les peptides peuvent également être immobilisés sur le support solide par l'intermédiaire du groupe amine après l'étape de division, au moyen de CNBr par l'intermédiaire d'homosérine lactone.

Title: Compositions pharmaceutiques empechant la consommation abusive d'opioides et d'autres drogues
Inventor: HIRSH JANE
IPC: A61K9/50
Filed: 2003-07-07
Abstract: L'invention concerne une composition pharmaceutique empêchant une consommationde abusive de drogues, laquelle composition permettant de réduire la probabilité d'administration impropre de drogues, en particulier de drogues comme les opioïdes. Dans le mode de réalisation préféré de l'invention, un médicament est modifié pour augmenter sa lipophilie. Dans des modes de réalisation préférés, le médicament modifié est dispersé de manière homogène à l'intérieur de microparticules constituées d'une matière qui soit se dissout très lentement dans l'eau, ou est insoluble dans l'eau. Dans certains modes de réalisation, les microparticules contenant la drogue, ou les particules de drogue, sont enrobées d'une ou de plusieurs couches d'enrobage, au moins une couche d'enrobage étant insoluble dans l'eau et de préférence insoluble dans un solvant organique, mais enzymatiquement dégradable par des enzymes présents dans le tube digestif humain. La composition empêchant la consommation abusive permet de retarder la libération de la drogue, même si l'intégrité physique de la formulation est altérée (par exemple, par le hachage au moyen d'une lame ou par un écrasement) et que la matière obtenue est placée dans de l'eau, reniflée ou avalée. Cependant, lorsqu'elle est administrée comme indiqué, cette drogue est libérée lentement depuis la composition, alors que la composition se désintègre ou se dissout progressivement à l'intérieur du tube digestif, par le biais d'une combinaison de dégradations enzymatiques, de l'action des agents de surface d'acides biliaires, et d'une érosion mécanique.
Patent CA-2493389-A1 (CA)
Inventor: BALLANTYNE SCOTT
IPC: A61B5/00
Filed: 2002-08-28
Abstract: The invention relates to an electromagnetic piezoelectric acoustic sensor (EMPAS). The sensor comprises a piezoelectric sensor plate spaced apart from an induced dynamic electromagnetic field, such as from an electromagnetic coil through which AC current flows. The electromagnetic field induces vibration in the sensor plate by fluctuating the aligned dipole moments of the piezoelectric material. Changes on the surface of the sensor plate can be detected by variation in resonance frequency of the sensor plate. The invention represents an improvement over conventional sensor methodologies in that no metallization of the sensor surface is required, and no permanent magnet is needed. The sensor may be used to detect absorption of molecules or biomolecular interactions between probe and target molecules.

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
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.

Title: Technique for routing a call to a call center based on the geographic origin of the call
Inventor: HUEY CHRISTOPHER A
IPC: H04Q7/36
Filed: 2005-02-17
Abstract: A telephone or other communications device may be identified by a telephone number based on a home area (e.g., "NPA" or area code). When a caller is traveling with a cellular telephone, for example, the caller may call an information assistance service to provide information about the place being visited. Based on the location of the originating switch, the call may be routed to the call center closest to the caller. Sometimes, the call is first routed to a call center closest to the phone's home area. In this case, the call center receives from the signaling stream associated with the call a caller location identifier or an originating switch identifier, which identifies the caller's location or vicinity. If another call center is closer to the caller than the first call center, the first call center reroutes the call to that closer call center. The invention allows an information assistance call to be routed to a call center closest to a caller's location rather than to the call center closest to the home area. This may be advantageous when a caller is traveling and wants to have an operator local to the caller's location handle the call.

Inventor: GARAKANI MEHRYAR KHALILI
IPC: H04L29/06
Filed: 2003-09-17
Abstract: Method and apparatus are described for differential MoIP bring-up and compression negotiation. A first differential, and, more particularly, overlapping, bring-up method involves initiating a bring-up of a first layer associated with a first modem; imposing a time delay; after the time delay, initiating a bring-up of a second layer associated with a second modem; and delaying completion of the first layer bring-up associated with the first modem until substantial completion of the second layer bring-up associated with the second modem. Two alternative differential, and, more particularly, sequential, V.8 modem relay link bring-up methods involve first bringing up a physical layer at a first leg while delaying bring-up of the physical layer of the second leg until completion of the bring up of the physical layer at the first leg, and thereafter completing XID exchange. All described methods and apparatus involve at least physical layer bring-up at both ends, and all optionally may involve the bring-up at either end also of error-correction (EC) layers and data compression layers.
