Patent CA-2378729-C (CA)
Title: Method for generating/regenerating a cipher key for a cryptographic method
Inventor: SCHWENK JORG
IPC: H04L9/08
Filed: 2000-07-06
Granted: 2010-02-16
Abstract: In a method for generating/regenerating an encryption key for a cryptographic method, the encryption key, as well as a public key being generated using a predefined deterministic method, from a large random number (seed), the seed is only generated on the user side, in that quantities known only to the user are consulted. Regeneration information (R), which is suitable for regenerating the seed and from which the seed is able to be derived deterministically by the trust center by linking only to information known to it, is generated on the user side and is stored so as to be secured against lost. In the event of loss of the encryption key, the seed is reconstructed by the trust center by linking the regeneration information to the secret information.

Title: Gallium complexes of 3-hydroxy-4-pyrones to treat infection by intracellular prokaryotes, dna viruses and retroviruses
Inventor: BERNSTEIN LAWRENCE R
IPC: A61K33/24
Filed: 2000-10-04
Granted: 2010-08-03
Abstract: Methods are provided for treating or preventing infections by obligate intracellular prokaryotes, including mycoplasma, rickettsia and chlamydia, retroviruses, and DNA viruses, including herpesviruses, papillomaviruses, adenoviruses and hepatitis B virus. Emphasis is placed on providing methods for the treatment of HIV disease. In addition to providing methods for treating HIV infection itself, methods are provided for treating an HIV  patient having a co-infection by another retrovirus, an obligate intracellular prokaryote, or a DNA virus. The methods involve the administration of 3:1 complexes of 3-hydroxy-4-pyrones with gallium, e.g., gallium maltolate.  Therapies incorporating gallium maltolate in combination with agents used against obligate intracellular prokaryote, retrovirus and DNA virus pathogens are also provided, as are multicombination therapies designed to treat co-infection by an obligate intracellular prokaryote, retrovirus or DNA virus in an individual infected by HIV. These multi-combination therapies rely on the ability of gallium maltolate to complement antiviral medication regimes against both HIV and other pathogens such as herpesvirus infections, including Kaposi sarcoma, CMV retinitis and blindness, and lymphomas, in patients immunocompromised by HIV infection.

Title: Connection setup strategies in optical transport networks
Inventor: NAGARAJAN RAMESH
IPC: H04B10/291
Filed: 2002-06-05
Granted: 2006-07-25
Abstract: An optical transport network comprises a number of nodes, or routers, which are coupled together via optical fibers. During a connection setup between a source node and a destination node, a node of the optical transport network initiates a cross-connect with an adjacent node and completes the cross-connect with the adjacent node without waiting for completion of any downstream cross-connects. The success of the connection operation to the destination node is checked by the node on the reverse pass. This results in completely pipelining the various cross-connect operations at each node. As a result, the connection setup time is of the order of a round-trip delay plus a single cross-connect time (independent of the number of nodes in the connection path).

Title: Multi-technology in-line eas deactivation apparatus
Inventor: BROWN CHRIS
IPC: G08B13/24
Filed: 2000-11-06
Granted: 2009-07-14
Abstract: A self-contained conveyor member including a plurality of EAS deactivators is adapted to connect in-line to an existing conveyor system for transporting goods at a manufacturer or distributor's site. The conveyor member has attached to it several commercially available EAS marker deactivators spaced apart to provide continuous coverage across the width of the conveyor and such that the deactivation field of each of the deactivators do not cause interference of the deactivation fields of the adjacent deactivators. EAS markers attached to articles being transported on the conveyor member will pass through at least one of the deactivation fields and will be deactivated. The deactivators selectively deactivate a variety of specific EAS markers such as RF and/or magnetomechanical EAS markers.

Granted: 2009-03-31
Abstract: L'invention concerne un séparateur centrifuge de type décanteur pouvant décharger directement, dans un cuve, une partie de boues dont la teneur en humidité est inférieure, de manière à réduire cette teneur en humidité et augmenter l'efficacité de séparation. Une vis hélicoïdale d'extraction tournant avec un écart de vitesse donné relativement à la cuve est placé dans le cuve tournant à haute vitesse. Un trajet de déchargement d'un pain d'essorage (20) est ménagé sur une paroi d'extrémité (2) de la cuve. Une ouverture (20a) du trajet menant à la cuve est pratiquée à proximité de la paroi périphérique intérieure de la cuve. Le trajet de déchargement a pour effet de restreindre le déchargement du pain d'essorage, et une couche sédimentaire présentant une couche de sédimentation épaisse est formée à proximité de l'ouverture si bien que cette partie du pain uniquement est déchargée par le trajet de déchargement sous la pression hydrostatique de la couche de sédimentation, ladite partie étant soumise à l'action de consolidation la plus puissante produite par la pression hydrostatique d'une force centrifuge agissant sur le sédiment, entre les couches de sédimentation accumulées à une extrémité de la cuve.

Inventor: ROHRBACH RONALD P
IPC: C10M175/06
Filed: 2001-05-08
Granted: 2011-09-20
Abstract: A fluid filter increases the useful life of the filtered fluid by removing contaminants therefrom, and may optionally provide for in-line delivery of additives to the filtered fluid. The filter may be an oil filter, a fuel filter, or other fluid filter. The fluid filter includes a casing which defines a hollow space therein, a mechanically active filter element within that space, and a chemically active filter element also retained within the hollow space proximate the mechanically active filter element. The chemically active filter element includes a nonwoven web made up of a plurality of fibers. Each fiber has a longitudinally extending internal cavity formed therein, and a corresponding longitudinally extending slot opening from that internal cavity to the outer surface of the fiber. Preferably each fiber has multiple lobes extending radially outwardly from a central stem, and each lobe cooperates with an adjacent lobe to define a longitudinally extending internal cavity and a corresponding slot therebetween. In order to remove contaminants or to supply additives to lubricating oil, the internal cavities, of each of the chemically active filter fibers, are supplied with a chemical reagent therein.

Filed: 2000-05-24
Granted: 2009-11-03
Abstract: Thermal bend actuator (28) has two spaced arms (31, 32) which are connected via rod elements (102). The rod elements (102) are themselves connected via torsion bars (110, 112, 114, 116, 118). One arm (32) is conductively heatable to cause bending of the actuator (28) on the application of an electrical current. The rod elements (102) and torsion bars (110, 112, 114, 116, 118) reduce the likelihood of unwanted bending modes taking place that could cause improper movement of the actuator (28). The actuator (28) may be used for moving an ink displacing paddle in the nozzle chamber of an ink jet device.

Abstract: A method and system for mapping logical identifiers to physical identifiers is provided. In one embodiment, a logical routing system allows each application, or more generally entity (e.g., user of an application), to register its logical identifier to physical identifier mapping when the application starts executing on a computer.
