Patent CA-2306992-A1 (CA)
Inventor: PERL JOHN
IPC: A61B17/00
Filed: 1998-09-23
Abstract: Cathéter (10) selon la présente invention qui comporte plusieurs passages pour l'administration d'une composition d'embolisation liquide par un premier passage, et l'administration d'un agent de solidification par un second passage. Ledit cathéter permet l'ajustement de la position longitudinale relative des deux passages pour réguler la solidification de la composition d'embolisation à l'intérieur du vaisseau sanguin. On utilise ledit système (10) de cathéter à plusieurs passages en introduisant le cathéter de manière intravasculaire sur un site d'anévrisme, en injectant une composition d'embolisation liquide par le premier passage et en injectant en même temps un agent de solidification par le second passage pour débarrasser la zone de l'anévrisme du sang qui est devenu saturé de solvant et remplacer ce sang par un agent de solidification neuf. La solidification régulée de la composition d'embolisation liquide à l'aide de l'agent de solidification permet de remplir l'anévrisme avec précision et rapidité, même lorsque cet anévrisme est situé de telle manière que la gravité ne provoque pas l'écoulement de la composition d'embolisation liquide dans l'anévrisme.
Patent CA-2313888-A1 (CA)
Inventor: MALKOWSKI ELIZABETH A
IPC: C08F2/48
Filed: 2000-07-13
Abstract: The invention comprises a composition and method for controlling the gloss of surface covering products through curing of the composition to create a wearlayer surface, and preferably on a floor covering product. The surface covering product preferably is prepared by application of an aromatic polyester acrylate composition including a flatting agent and/or hard particles, and at least one free-radical generating compound to a substrate, and then the coating is partially cured by exposure to low peak irradiance UV  light in either ambient or inert air, followed by fully curing the coating with high peak irradiance UV light in preferably an inert atmosphere to form a low gloss abrasion resistant wearlayer surface. Alternatively, a high gloss wearlayer surface is obtained by solely exposing the preferred composition to high peak irradiance UV light in ambient atmosphere.  Furthermore, a differential gloss flooring product is obtained by using the present inventive method described herein.

Title: Technique for parametric coding of a signal containing information
Inventor: SINHA DEEPEN
IPC: G10L19/00
Filed: 2000-11-22
Abstract: In a communications system, parametric coding in accordance with the invention is implemented to generate a representation of a stereo audio signal, which is composed of a left channel signal (L) and a right channel signal (R). To efficiently utilize transmission bandwidth, such a representation contains (1) information concerning only one of the L and R signals, and (2) parametric information based on which, together with (1), the other signal can be recovered. Because of the design of the parametric coding, the representation advantageously captures localization cues of the stereo audio signal, including intensity and phase characteristics of L and R. As a result, tie stereo audio signal recovered from the transmitted representation affords a high stereo quality.

Title: Method and apparatus for testing image sensing circuit arrays
Inventor: CHAMBERLAIN GEORGE
IPC: H01L31/10
Filed: 2001-03-13
Abstract: A method and apparatus for testing an image sensor array such as a C-MOS  imager which has sensing circuits arranged in rows and columns and wherein the sensing circuits include photosensitive devices is described. A reset voltage is applied to the photosensitive device in each of the sensor circuits such that at least adjacent circuits are reset to different voltage levels. The voltage on each photosensitive device is detected and compared to an expected level to determine if and where any faults may exist in the sensing circuits or lines in the array. A different reset voltage may be applied to each of the sensor circuits, however in one embodiment, a supply with only two voltage levels may be used. One voltage level is applied to every second column to provide a supply voltage to the photosensitive devices and to every second row to generate a reset enable signal for the photosensitive devices. The second voltage level is applied to the remaining columns and rows resulting in different reset voltage levels on adjacent sensing circuits.

Title: Shock absorber assembly for reducing break tension in an asphalt-coated sheet
Inventor: ASCHENBECK DAVID P
IPC: B65H20/24
Filed: 1999-12-27
Abstract: A shock absorber assembly (50) for a finish looper (32) that reduces breaks of an asphalt-coated sheet (20). The finish looper (32) includes a plurality of  looper rolls (34) forming a plurality of free hanging loops of the asphalt- coated sheet (20). The shock absorber assembly (50) is mounted on a frame structure (52) capable of relative movement with respect to the looper rolls  (34). The shock absorber assembly (50) includes a plurality of rolls includi ng an indexing roll (54), a guide roll (70), and a shock roll (64) positioned between the indexing roll (54) and the guide roll (70). Just prior to the la st free hanging loop (62) being completely payed out, the shock roll (64) is in  an up position and the indexing roll (54) is in a down position. When the asphalt-coated sheet (20) is further payed out, the asphalt-coated sheet (20 ) engages the indexing roll (54) and causes it to pivot (58) from the down position to an up position. The weight and acceleration of the adjacent, upstream free hanging loop (74) causes the shock roll (64) to move from the up position to the down position. The movement of the indexing roll (54) and shock rolls (64) shortens the path length of the asphalt-coated sheet (20) through the shock absorber assembly (50) and reduces the acceleration rate o f the sheet (20)in the next loop, thereby reducing breakage of the asphalt- coated sheet (20) when it is payed out from the last free hanging loop (62).  A method of reducing breaks in the asphalt-coated sheet (20) is also described .
