Patent CA-2401234-A1 (CA)
Inventor: SOWA MICHAEL G
IPC: A61B5/00
Filed: 2001-04-12
Abstract: L'invention concerne un appareil permettant d'évaluer, dans le visible et le proche infrarouge, des paramètres tissulaires associés à l'état des tissus. Ledit appareil comprend une source lumineuse permettant d'éclairer les tissus dans la région spectrale visible et proche infrarouge. Lesdits tissus absorbent une certaine quantité de lumière, même si une grande partie de la lumière est diffusée à l'intérieur des tissus. Cette diffusion provoque la dispersion de la lumière dans toutes les directions, une fraction de la lumière diffusée pénétrant dans les tissus avant d'être renvoyée hors de la surface. La lumière renvoyée est collectée par un système de détection permettant de disperser la lumière selon ses composantes de longueur d'onde. La lumière peut être collectée au moyen de sondes à une ou plusieurs fibres optiques, qui entrent dans un dispositif dispersif de sélection de longueurs d'onde où la lumière dispersée est détectée au moyen d'un dispositif de détection des photons en milieu spectroscopique. De façon similaire, la lumière renvoyée peut être détectée par imagerie au moyen d'un système optique non dispersif de sélection et d'imagerie des longueurs d'ondes. La lumière renvoyée détectée dans les tissus contient des informations spectrales uniques au sujet de l'état de santé desdits tissus. Les images et les spectres ainsi acquis sont affichés en temps réel sur un écran, de manière à caractériser l'état de santé des tissus.

IPC: G05G15/00
Filed: 2001-05-07
Abstract: The invention relates to an actuating device (1) for displacing a control device (3), which is subjected to the action of force counter to the direction of displacement (2). Said actuating device comprises an actuating element, which, inside a device housing (4), can be axially displaced in a direction of displacement by a turning spindle (5) of an advancing device (6). The turning spindle is connected in a rotationally fixed manner to a turning sleeve (8), which is rotatably mounted in the device housing (4) and which surrounds the turning spindle. Said turning sleeve is fixed, in relation to an annular flange (9) that is connected to the device housing in a rotationally fixed manner, counter to an advance turning direction (11) of the turning spindle by means of a spiral spring (10). An emergency disengagement device for resetting the actuating element counter to the direction of displacement is assigned to the spiral spring. The aim of the invention is to improve the actuating device by providing it with a compact and simple design and, at the same time, by enabling the winding of the spiral spring to be easily and precisely adjusted with regard to the torsional strength of the connection of the turning sleeve and the annular flange. To this end, the emergency disengagement device comprises a tension sleeve (13) for the spiral spring that is detachably held in a tensioning position. Said tension sleeve can be torsioned between a tensioning position and a final tensioning position and is subjected to the action of force toward its final tensioning position.

IPC: F16J15/12
Filed: 2002-10-30
Abstract: A valve cover gasket has a perforated central core of metal including protrusions extending from planar sides of the core. Silk screened on each side of the core is a silicone foam rubber layer adapted to replace traditional cork gasket structures used for same purpose. The silicone rubber layers include a foaming agent that causes the material to expand during an oven-curing period. The amount of expansion of the silicone rubber coating is up to three times the thickness of the coating originally applied. As disclosed, the oven cure is for approximately minutes at 300 degrees Fahrenheit. The protrusions prevent the silicone rubber material from being fully compressed; the protrusions are designed not to flatten under normal gasket compression loads. The peaks of the protrusions act as compression loads stops to limit amount of permissible compression of the silicone rubber layers.

Title: System and method for concentration and load-balancing of requests
Inventor: FERWERDA PAUL
IPC: H04L29/06
Filed: 2001-07-17
Abstract: The invention relates generally to distribute computing environments and specifically to a system and a method for reducing the number of Object Request Broker (ORB) connections in an Internet Inter-ORB Protocol (IIOP) environment. Prior solutions required a n x m number of connections to handle requests from clients (82,84,86,88) to remote servers (92,94,96,98). The solution described allows there to be only m connections (81,91) through an intelligent concentrator (90), which significantly reduces requirements and allows scalability. Prior solutions did not utilize multiple intelligent master concentrator processes (90) to handle concentrator failure or dynamic scalability.

Abstract: Les piles à combustible HT-PEM utilisées à température plus élevée sont moins sensibles aux contaminations par CO que les piles à combustible PEM utilisées à température normale. L'invention vise à régénérer d'éventuelles contaminations par CO provoquées par le démarrage de la pile à combustible. A cet effet, on utilise les piles à combustible HT-PEM en mode pulsé sur une durée déterminée lors du chauffage ou à l'état chaud. Ainsi, il est possible de régénérer des électrodes des piles à combustible contenant du CO. Pour la mise en oeuvre du procédé de régénération de l'unité de commande et/ou de régulation (120), le dispositif de piles à combustible composé d'au moins un module de piles à combustible regroupant un empilement de piles à combustible HT-PEM, et d'une unité de commande et/ou de régulation correspondante destinée à la commande de procédé, comporte également une unité d'impulsion (125) activant la pile à combustible (110) en mode pulsé en fonction de paramètres prédéfinissables.

Inventor: SURJAATMADJA JIM B
IPC: E21B43/26
Filed: 2003-09-09
Abstract: Changes occurring downhole during a fracturing process can create or reflect pressure signals. Capturing and evaluating such pressure waves during fracturing enables personnel to monitor, in real time or later, what happens downhole. When a fracture extends, a burst of acoustic noise is embodied in a pressure wave or signal, as is noise coming from other sources. By transforming time-based pressure signals to a frequency base, one can monitor this acoustic noise. In a particular implementation, a waterfall plot of frequency spectra at successive time slices of the original signal is used to determine frequency ridges, such as a ridge of decreasing frequencies indicates fracture extension and a ridge of increasing frequencies indicates either closure or proppant backing up in the fracture. Filtering, such as wavelet filtering, can be used. A fracturing process can be controlled in response to determining whether the fracture is extending.
