Abstract: Cette invention porte sur l'utilisation conjointe de l'électronique transistorisée et de la fonction neuronale dans le cadre de nouvelles analyses électrophysiologiques à fort rendement pour la détermination des effets chroniques et aigus d'un composé sur des fonctions cellulaires. L'intégration de l'électronique, de la chimie des phénomènes de surface, des biotechnologies et des neurosciences fondamentales débouchent sur un type d'analyse dans lequel l'élément rapporteur est une batterie de cellules électriquement actives. Cette technologie novatrice convient pour des analyses de neurotoxicité et pour le criblage de composés à partir de la chimie combinatoire, de l'analyse fonctionnelle des gènes et les applications fondamentales des neurosciences. Le système selon l'invention permet d'analyser comment le potentiel d'action est interrompu par des médicaments ou des toxines. Les différences entre potentiels d'action sont dues à diverses toxines qui agissent sur des chemins biochimiques différents, ce qui, à son tour, a une incidence sur les canaux ioniques et entraîne pour chaque toxine une modification en propre de la forme du pic du potentiel d'action. Des algorithmes utilisés pour analyser les écarts entre les formes de pic des potentiels d'action renseignent sur le ou les chemin(s) touchés par la présence d'un nouveau médicament ou d'un nouveau composé dont certains aspects de la fonction la cellule considérée peuvent être déduits. On peut exploiter cette information pour déterminer la catégorie fonctionnelle de l'action biochimique d'un composé inconnu. La chimie de surface, qui permet d'établir un joint d'impédance élevée entre la cellule et la micro-électrode métallique, constitue un aspect important de l'invention. Ce joint recrée l'interface qui rend possible l'électrophysiologie par patch-clamp et micropipettes, avec électrophysiologie extracellulaire sur une plaquette de microélectrodes. Ainsi, grâce à cette invention, il est possible d'utiliser des cellules vivantes à des fins diagnostiques et d'effectuer des analyses en temps réel et à cadence élevée de la fonction cellulaire.
Patent CA-2376301-A1 (CA)
Inventor: ABEND KENNETH
IPC: G01S15/89
Filed: 2000-06-14
Abstract: A thinned (greater than ~ wavelength element spacing) array of ultrasound transducers is used to form a large number of received near-field focused beams within an insonated region. Since array thinning allows for unambiguou s scanning or imaging over only a limited region or segment, a set of transmitters are fired one at a time to insonate one segment at a time. The receiver is an array of elements, all receiving simultaneously, and a plurality of transmitters is used, each aimed at a different segment. The transmit beam is steered by switching between transmitters, and a large numb er of focused receive beams are formed digitally for each transmitted pulse. Th e transmitters are designed to provide very little energy in the direction of the receiver spatial ambiguities or "grating lobes". Also provided is a thinned array wherein the roles of the transmitters and receivers as describ ed above are interchanged.

Patent CA-2386975-A1 (CA)
Title: Novel multimode fiber for narrowband bragg gratings
Inventor: SIPE JOHN EDWARD
IPC: G02B6/036
Filed: 2002-05-16
Abstract: A novel multimode fiber structure with modal propagation characteristics tailored to facilitate the creation of narrowband, high reflectivity, fiber Bragg gratings is disclosed. The fiber structure comprises concentric cylindrical shells of higher and lower refractive index material. A full vector, second order finite element method is used to analyze the proposed multimode fiber structure.  Simulations of the modal profiles show that high order modes are localized to particular high refractive index shells. We present the theoretical characterization of the modal propagation constant as a function of inner shell radius, shell separation, and harmonic mode parameter. It is shown that a fiber with a minimum inner shell radius of at least 25.lambda. (where .lambda. is the vacuum wavelength), and a minimum shell separation of at least 10.lambda. provides a reasonable trade off between fiber size and grating performance. A simulation of the multimode fiber grating shows that a grating with a FWHM bandwidth on the order of 10-4.lambda. is theoretically possible if optical power is launched strictly into modes with angular harmonic parameter p=1.

Filed: 2000-12-12
Abstract: L'invention concerne un coupleur de guide d'ondes optique élargissant la condition de correspondance de phase et facilitant le couplage entre un guide d'ondes optique et un résonateur. La lumière produite dans un guide d'ondes optique multimode (1) est directement couplée avec un résonateur microsphérique (2) par l'intermédiaire d'une lumière évanescente. Etant donné la petite taille de ce résonateur microsphérique (2), l'efficacité du couplage entre le résonateur microsphérique (2) et le guide d'ondes optique multimode (1) est faible. Par conséquent, sous la condition de non-résonance, l'influence du résonateur microsphérique (2) est faible, la propagation de lumière à travers le guide d'ondes optique multimode (1) n'étant alors pas influencée. Toutefois, étant donné que l'intensité de la lumière stockée dans le résonateur microsphérique (2) est élevée sous les conditions de résonance même si l'efficacité de couplage est faible, le résonateur microsphérique (2) produit de la lumière dont l'énergie est approximativement la même que celle de la lumière produite dans le guide d'ondes optique multimode (1). Ainsi, une forte condition de couplage est toujours satisfaite, le coupleur de guide d'ondes optique fonctionnant comme un filtre du fait de l'interférence entre la lumière produite dans le guide d'ondes optique (1) et la lumière ayant traversé le résonateur microsphérique (2).
