Patent CA-2327441-A1 (CA)
Inventor: MOORBY PHILIP R
IPC: H04N13/221
Filed: 1999-03-26
Abstract: Cette invention se rapporte à un procédé de poursuite de traits sur plusieurs trames d'images apparentées, par développement d'un réseau dense de traits et de leurs trajectoires sous la forme d'une grille déformable à espacements réguliers, dans laquelle les vecteurs de chaque point de trait nodal de la grille sont dérivés par un processus apparenté au flux optique. Le réseau de traits dense qui en résulte peut être appliqué à des techniques telles que la poursuite de formes bidimensionnelles sur des trames, l'estimation de trajectoires tridimensionnelles de points de traits choisis, l'estimation de trajectoires de caméras tridimensionnelles à partir de multiple points de traits ou la récupération de structures de scènes tridimensionnelles estimées (y compris les profondeurs estimées de surfaces d'objets) à partir de données de poursuite de traits.

IPC: C08F214/22
Filed: 2000-12-20
Abstract: La présente invention décrit la préparation puis la copolymérisation ou la terpolymérisation de monomères trifluorovinyliques à extrémité nitrile avec des monomères fluorés. Ce procédé conduit à la synthèse de nouveaux élastomères nitriles fluorosulfonés réticulables présentant de très basses températures de transition vitreuse (T g), une bonne résistance aux acides, au pétrole et au x carburants et de bonnes propriétés de mise en oeuvre. Ces élastomères contiennent, à titre d'exemple, de 2 à 10 % en moles de 5,5,6-trifluoro-5- hexènenitrile (F-CN), de 20 à 30 % en moles de perfluoro(4-méthyl-3,6- dioxaoct-7-ène)fluorure de sulfonyle (PFSO2F) et de 66 à 78 % en moles de fluorure de vinylidène (VDF ou VF2). Dans ce cas précis, ils sont préparés p ar copolymérisation radicalaire du F-CN et du PFSO2F ou par terpolymérisation radicalaire du F-CN, du PFSO2F et du VDF en présence de différents amorceurs organiques comme par exemple des peroxydes, des peresters ou des diazoïques. D'autres oléfines fluorées telles que le fluorure de vinyle, le trifluoroéthylène, le chlorotrifluoroéthylène, l'hexafluoropropène, le 1,2-difluorodichloroéthylèn e, le 1,1-difluoro-2-chloroéthylène, ou le 1-hydropentafluoropropène peuvent aussi être utilisées dans la tétrapolymérisation. En outre, la présente invention concerne un procédé de réticulation de ces polymères.
Patent CA-2329441-A1 (CA)
Title: Laminated integrated circuit package
Inventor: PLEPYS ANTHONY R
IPC: H01L23/498
Filed: 1999-03-31
Abstract: A low-cost integrated circuit package is provided for packaging integrated circuits. In preferred embodiments, the package comprises a flexible circuit that is laminated to a stiffener using a dielectric adhesive, with the conductive traces on the flexible circuit facing toward the stiffener but separated therefrom by the adhesive. The conductive traces include an array of flip-chip attachment pads. A window is formed in the stiffener over the attachment pad array, such as by etching. The adhesive is then removed over the attachment pads by laser ablation, but left in place between the pads, thus forming a flip-chip attachment site. In preferred embodiments, this invention eliminates the need for high-resolution patterned adhesive, and it also eleminates the need for application of a solder mask at the flip-chip attachment site, because the remaining adhesive performs the solder mask function of preventing bridging between attachment pads. This package provides a die attachment site having a high degree of planarity due to tensile stresses formed in the flexible circuit and adhesive layers during lamination of those layers to the stiffener. Embodiments of this invention may be used with TBGA, frangible lead, and other packaging technologies.

Patent CA-2336274-A1 (CA)
Title: Method for optimizing the available transmission capacity at subscriber line networks
Inventor: SCHRODER STEFAN
IPC: H04J3/16
Filed: 1999-02-08
Abstract: In customer access networks wherein information is exchanged according to a transmission method xDSL, a problem arises in that the maximum available transmission capacity is highly dependent on physical conditions of compatibility. If these conditions are modified, the modems must adapt themselves again. If the initial transmission capacity is not reached any longer, the xDSL line is taken out of service. The present invention solves this problem by establishing a communication channel between the modem and a central control logic.

Abstract: Apparatus for generating foam for use in fire fighting having two plates (50, 60) housed in a chamber (10) which respectively introduce pressurized air and a water/surfactant solution between the two plates (50, 60) where foam is generated and emitted from an aperture (40) on the side of the chamber (10).  The pressurized water/soap solution enters the chamber (10) through an orifice (52) in one plate (50). Pressurized air enters the chamber (10) through a number of channels (64) bored through the other plate (60), such channels (64) appearing in an annular groove (63) which circumscribes the water inlet (52). The restricted area (70) balances the pressure between the incoming water and the incoming air by achieving an equilibrium at some particular radius out from the center of the two plates (50, 60). The apparatus also includes a pressure regulating system (182) that automatically cuts off the flow of pressurized water and air when the foam dispensing nozzle (174) is turned off.

Abstract: L'invention concerne des composés 4',5'-dihydropsoralène 5'-substitués, (5) portant des acides tertiaires (et des sels de ceux-ci), des fractions d'ammonium quaternaire ou des fractions organomercurielles. L'invention concerne également des mercuriméthyl-2-3-dihydro-benzofuranes 2-substitués représentés par la formule (7). L'invention concerne également des synthèses directes polyvalentes réalisées à l'aide de composés inconnus jusqu'alors, tels qu'un 3-R-4,8-diméthyl-4',5'-dihydro-5'-bromométhylpsoralène ou un 3-R-4,8-diméthyl-4'-5'-dihydro-5'-iodométhylpsoralène permettant de préparer un ensemble à diversité structurelle de psoralènes et de benzofuranes partiellement réduits. La présence d'une charge d'ammonium permanente dans ces psoralènes empêche le passage membranaire, et la mono-insaturation empêche la réticulation d'un ADN nucléaire, ce qui réduit les effets secondaires mutagènes/carcinogènes associés aux thérapies dérivées du psoralène. La présence d'une valence fonctionnelle de mercure produit un groupe de liaison cellulaire réactif sur ces psoralènes à cytotoxicité unique sans activation de la lumière, et une amélioration de l'activité cytotoxique par activation de la lumière. L'invention concerne également les psoralènes partiellement réduits et quaternarisés, les psoralènes amino substitués, les psoralènes mercurio affichant une pharmacologie impressionnante contre les kératinocytes PAM 212, une lignée cellulaire modèle utilisée comme système de test pour mettre en évidence la cytotoxicité épidermique et le cancer. Les composés de l'invention possèdent également une activité antimicrobicide utile dans les agents pharmacologiques pour mammifères (par exemple, pour le traitement de la tuberculose), ainsi que dans le contrôle de la croissance de micro-organismes sur des substrats et dans des systèmes aqueux.
