Patent CA-2394860-A1 (CA)
Title: Aiguille hypodermique munie d'une pointe poreuse et procede d'utilisation
Inventor: HOLMES DAVID R JR
IPC: A61K48/00
Filed: 2000-12-18
Abstract: L'invention concerne des aiguilles chirurgicales présentant une partie distale poreuse de laquelle un liquide d'injection s'écoule ou suinte dans plusieurs directions sous une pression d'injection, lorsque la partie distale poreuse de l'aiguille est insérée à l'intérieur d'une surface du corps. La partie distale poreuse de l'aiguille peut être fabriquée avec du carbone poreux, du métal, de la céramique ou un polymère. Elle présente, de préférence, un gradient d'impédance décroissant par rapport au fluide s'écoulant vers la pointe de l'aiguille pour compenser la chute de la pression d'injection lorsque le liquide se déplace vers la pointe, ce qui assure un écoulement uniforme du liquide d'injection le long du trajet d'injection. L'aiguille est adaptée pour se fixer à un cathéter ou à une seringue. Dans une autre forme de réalisation, on décrit un ensemble chirurgical dont une partie distale poreuse ayant des caractéristiques d'écoulement du liquide similaires est située le long de l'extrémité distale d'un cathéter, et une pointe d'aiguille est fixée à l'extrémité distale du cathéter (p. ex. un cathéter orientable) pour percer un tissu. Un cathéter-guide peut être utilisé pour diriger les dispositifs de l'invention vers un site d'injection interne éloigné. Les dispositifs et procédés de l'invention peuvent être utilisés pour injecter des liquides (notamment des liquides contenant des acides nucléiques destinés à un traitement génique) dans des parois ou des tissus d'un organe interne, tel qu'un coeur palpitant, sans déperdition importante de liquide et sans lésion notable du tissu provoquée par le liquide d'injection.

Title: Low nitrogen oxides emissions using three stages of fuel oxidation and in-situ furnace flue gas recirculation
Inventor: ASHWORTH ROBERT A
IPC: F23L9/02
Filed: 2001-06-01
Abstract: A method and apparatus for reducing NOx emissions from the combustion of carbonaceous fuels using three stages of oxidation and second stage in-situ furnace flue gas recirculation. In the first stage, a partial oxidation combustor is used to partially combust the fuel in the presence of heated combustion air. The fuel gas produced in the partial oxidation process is passed to a second stage partial oxidation combustor while molten slag is removed and disposed of. A second preheated combustion air is introduced into the second stage combustor to produce a reducing flue gas and is injected into the furnace in such a way as to create the desired in-situ furnace flue gas recirculation. A third combustion air is mixed with the flue gas in a third stage of combustion to substantially complete the combustion process.  Preheated steam may be added to the first or second stages of combustion.

Title: Terrain conforming track assembly
Inventor: BRAZIER GLEN
IPC: B62D55/04
Filed: 2003-03-25
Abstract: An endless track assembly that mounts to a wheeled vehicle. The assembly provides 1) a track suspension having fixed or adjustable, independently biased sets of idler wheels to vary the track contour without affecting track tension, 2) an eccentric bearing housing at a drive sprocket controls track tension, 3) a contoured peripheral edge at the drive sprocket prevents ice and mud buildup, 4) rubber-coated, plastic idler wheels facilitate track movement, 5) a multi-vehicle compatible adapter mounting plate accommodates a variety of vehicles, 6) a rotation limited torsion coupler and/or rotation limiting coupler arms prevent track contact with the vehicle, 7) a locking steering arm coupler prevents loss of steering control, and 8) shaped track lugs and channels clear and direct debris away from the track suspension and drive assembly. The improved suspension particularly supports sets of idler wheels in pivotal relation to the track support frame and resiliently biases a pre-tensioned rocker arm that links adjacent suspension arms mounted to the adjoining idler wheels. Suspension arm movement induces expansion and contraction of tension springs coupled to the rocker arms to augments shape changes at the track contact surface to optimize traction and steering control.
Patent CA-2423625-A1 (CA)
Title: Optical transmission system
Inventor: GHIGGINO PIERPAOLO
IPC: H04B10/43
Filed: 2001-09-28
Abstract: In an optical data transmission system, high frequency pulsed optical signals are transmitted along an optical fibre. These pulses are attenuated and distorted by transmission over long optical fibres, making detection of data difficult at the receiving end. The allowable pulse profile is determined by an eye diagram, and the invention uses an eye diagram which is non-symmetrical with respect to logic 1 and 0 levels. By positioning the eye diagram closer to the logic 0 level, detection in the presence of noise introduced during transmission of the optical pulses, can be significantly improved.
Patent CA-2423869-A1 (CA)
Title: Hdtv up converter
Inventor: LE DINH CHON TAM
IPC: H04N7/01
Filed: 1999-04-01
Abstract: An electronic apparatus for converting a standard video signal having 59.94 fields per second into an HDTV video signal having 60.00 fields per second, by adding a number of video fields into each sequence of 1000 video fields. The apparatus detects the best moment for adding the new video field, so that the human eye does not perceive an abrupt change in the video image, by detecting the best motion conditions which occurs either when the image motion is high or very low. For adding the new video field, the apparatus uses an interpolation technique for creating two interpolated video fields which are inserted in place of one existing video field which is deleted. The apparatus also comprises a de-interlacer module for deinterlacing the 60 Hz video image, by using an advanced interpolation technique for calculating the missing video lines. The proposed technique involves directional interpolations of the missing lines pixels in various directions and selection of the best interpolation direction for the creation of each pixel of the missing video lines. The corresponding de-interlacer apparatus comprises a novel edge direction detector which performs the mentionned interpolations in all interpolating directions and then selects the best direction for performing the interpolation for each interpolated pixel, based on the quality of the performed interpolations.
