Abstract: La présente invention concerne un cathéter à électrodes (2) comportant une poignée (4) sur laquelle est monté une tige (6) de cathéter. L'extrémité distale (10) de la tige du cathéter porte une pluralité d'électrodes (12). Des fils (12) bi-fonction partant d'un connecteur électrique (14) placé sur la poignée traversent des lumières axiales séparées (16) dans la tige du cathéter et aboutissent aux électrodes. Les fils bi-fonction sont physiquement assujettis par leurs extrémités distales et proximales respectivement à l'extrémité distale de la tige du cathéter et à la poignée de façon que la rotation de la poignée crée un couple se transmettant à l'extrémité distale de la tige du cathéter par l'intermédiaire des fils bi-fonction. Chaque fil bi-fonction présente une résistance électrique n'excédant pas environ 0,80 Φ/cm et une rigidité de torsion d'au moins environ 0,25 à 1,0 pouce-once (17654 à 70616 dyne-cm) par longueur de 110 cm de tige de cathéter sous une rotation de 3 tours de l'extrémité proximale de la tige du cathéter. Cette construction permet de réaliser simplement un cathéter à électrodes à couple de torsion et peu coûteux.

Abstract: A multiple recording layer rewriteable phase-change optical disk (12) and disk drive uses a reverse writing type of reversible phase-change material as the recording layer (53) nearest the incident laser light. The disk has a light-transmissive substrate (50) onto which the laser light is incident. The substrate supports at least two spatially-separated multilayer recording stacks (90, 92), each stack including an active recording layer (53, 64) of reversible or rewriteable phase-change material. The recording stack (90) located nearest the substrate (50) on which the laser light is incident includes a reverse writing type of reversible phase change material, i.e., a phase-change material with an amorphous starting phase that is recorded onto by laser heating that converts data regions to the crystalline phase. This first recording layer (50) has a dielectric layer (51) in contact with it that has a high index of refraction relative to the adjacent recording layer and that acts as an optical interference film to provide a constructive optical interference effect in the recording stack. The optical interference film optimizes the contrast, reflectivity, and transmissivity of the recording stack. The optical interference film is also nonabsorbing so that laser light can pass through it to focus on a recording layer (64) in a farther recording stack (92). This allows the farther recording layer to be written using reasonable laser power.

Abstract: A collaboration system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of data at intermediate hops, as well as video mosaicing and cut-and-paste technology.
