Patent CA-2434058-A1 (CA)
Inventor: CHANG JOHN Y
IPC: A61B18/24
Filed: 2002-01-17
Abstract: La présente invention concerne des procédés et un dispositif permettant d'apporter des substances ou un appareil à des sites cibles situés à l'extérieur des vaisseaux sanguins dans le corps d'un homme ou d'un animal. Un cathéter est introduit dans la paroi d'un vaisseau du système vasculaire, positionné et orienté à l'intérieur d'un vaisseau sanguin à proximité du site extravasculaire cible et un organe de pénétration est avancé par le cathéter pour pénétrer ainsi depuis l'extérieur, la paroi du vaisseau sanguin en direction du site cible. Un cathéter d'apport est ensuite introduit à travers une lumière de l'organe de pénétration jusqu'au site cible. Une substance ou un appareil désiré est ensuite apporté au site cible ou prélevé de ce site cible. Dans certaines applications, l'organe de pénétration peut être rétracté dans le cathéter qui traverse la paroi du vaisseau puis ce même cathéter peut être enlevé, alors que le cathéter d'apport reste en place pour apporter de manière chronique ou continue une ou des substances et/ou pour fournir des informations ou des échantillons provenant du site cible. Dans d'autres applications, un cathéter d'apport comprenant un élément d'occlusion ou un ballonnet peut être avancé dans une veine ou une veinule et l'élément d'occlusion ou le ballonnet peut être utilisé pour obstruer la lumière de la veine ou de la veinule pendant ou après l'injection d'une substance par l'intermédiaire du cathéter, de sorte que la substance ne soit pas entraînée par l'écoulement normal du sang dans les veines et reste dans la veine ou la veinule pendant un temps suffisant pour produire l'effet souhaité (par exemple, pénétrer dans des tissus adjacents en traversant des lits capillaires drainés par cette veine ou cette veinule).

Title: Global database management system integrating heterogeneous data resources
Inventor: CUI ZHAN
IPC: G06F17/30
Filed: 2002-03-15
Abstract: A database management system is disclosed for solving distributed queries across a range of resources. In known systems, database retrieval from multiple sources suffers from problems of reconciliation of data between resources and resource or data incompatibility. The invention allows full database integration even in the case where a database includes a plurality of disparate database resources having differing ontologies (data structures). The system has an ontology server which is used to store the ontologies of various database resources and the query engine is designed to consult the server so that it can construct a query that will operate effectively across the disparate database resources.

Title: Stationary welding device and method for longitudinal welding of profiles
Inventor: KRUECKELS THOMAS
IPC: B23K26/26
Filed: 2003-10-17
Abstract: A method and a device for the longitudinal welding of profiles (25, 13) are provided in which a profile (13) that is to be provided with a weld seam (22, 23) is guided through a welding device (1), and in the welding device (1) a welding head (14, 15) produces a weld point (20, 21) on the profile (13), in order to manufacture a weld warn (22, 23). The profile movement is braked at selectable intervals from an essentially constant production speed down to the point at which the profile (13) is at a standstill, and is subsequently accelerated back to the production speed, while the application of welding energy to the profile (13) is switched off below a threshold transport speed. in order to avoid a gap in the resulting weld seam (22, 23), according to the present invention a welding head control system is used, with the aid of which the location of the weld point (20, 21) is moved in the direction of transport (12) of the profile (13), beginning from an initial point, each time the profile (13) is at a standstill, the weld point (20, 21) being moved back to the initial position, against the direction of transport (12) upon restarting of the transport movement, after the threshold transport speed has been reached.

Title: Magnetic circuit arrangement for a transducer
Inventor: BITTO ENNIO
IPC: G01F1/84
Filed: 2002-04-24
Abstract: The magnetic circuit arrangement, which is preferably used in a fluid-measuring transducer, comprises at least one coil which is traversed in operation by a current. It further comprises two armatures that are fixed to two flow tubes vibrating in phase opposition. The coil is float-mounted by means of a holder to a double flow tube configuration formed by the flow tubes. The armatures are shaped and aligned relative to each other in such a manner that magnetic fields produced by means of the magnetic circuit arrangement are essentially concentrated within the magnetic circuit arrangement, whereby the latter is also largely insensitive to extraneous magnetic fields. The magnetic circuit arrangement is marked by a long service life and, particularly if the transducer is used for fluids with high and/or varying temperatures, by constantly high accuracy in operation.

Title: Method of computing wavelets temporal coefficients of a group of pictures
Inventor: ZILIANI FRANCESCO
IPC: H04N19/63
Filed: 2003-10-22
Abstract: The invention relates to a method of computing wavelets temporal coefficients of a GOP (Group Of Pictures) the length of which is 2n. A controlled temporal transform is applied recursively generating n decomposition levels. Each decomposition level comprises the mean and the mean difference of each couple of input signals. During the last n-1 decomposition levels each decomposition level transform block is controlled by a control signal corresponding to the sum of two temporal mean differences outputted from the previous decomposition level. The corresponding temporal means of said previous decomposition level are the input signals for said transform block. When the said control signal is equal to zero the output values of said transform block is the temporal mean value and the temporal mean difference of the input signals. When the control signal is different from zero, the output signals are the said input signals.

Title: A method for manufacturing rubber weather stripping
Inventor: TARTER-GARRO MANUEL
IPC: B05B12/24
Filed: 2003-12-02
Abstract: The machine is fed with rubber mesh that has ducts all along the run, which expel air in order to ensure the rubber mesh slides along smoothly inside the machine. A system of bevelled blades separated from each other by semicircular shaped grooves apply pressure to the mesh when it passes over a metal roller that has semicircular grooves on its surface that coincide exactly with those of the upper part. The cavity created between both makes a perfectly round cut across the foam rubber, and welded seams along the whole of its length. A nozzle system releases the glue at a high temperature. A double system releases the glue at a high temperature. A double winding system that inserts the hubs alternately into the axes performs the rewinding operation, without the process having to be stopped and once completed, the weather stripping is packaged in cases that are equipped with special parts.
