Patent CA-2197608-C (CA)
Inventor: TAYLOR CHARLES S
IPC: A61B19/00
Filed: 1997-02-14
Granted: 2000-02-01
Abstract: L'invention a trait à des instruments et à des techniques utilisant une pression d'aspiration (succion) ou un vide obtenus au moyen d'un instrument chirurgical, pour maintenir en place une partie de la surface d'un coeur qui bat, de manière à faciliter la réalisation d'une intervention chirurgicale. Les instruments appliquent une pression d'aspiration à plusieurs points du coeur, de sorte qu'une partie du coeur est maintenue en place par la succion appliquée au moyen de l'instrument chirurgical. Parce que l'instrument maintient en place le tissu et que les instruments demeurent toujours à la même distance de la partie du coeur faisant l'objet de l'intervention chirurgicale, l'instrument peut également servir de support ou de plate-forme pour faciliter l'utilisation d'autres instruments au site. Dans certaines applications, les instruments décrits sont structurés de manière à faciliter l'utilisation d'instruments chirurgicaux supplémentaires de sorte que l'emplacement du dispositif de succion permet au chirurgien de manipuler facilement d'autres instruments pendant l'intervention chirurgicale. La pression d'aspiration est préférablement appliquée par plusieurs éléments pouvant se trouver sur une surface presque plane de l'instrument qui est en contact avec les tissus cardiaques.

Title: Http distributed remote user authentication system
Inventor: REICHE ALBERT F
IPC: H04L29/06
Filed: 1997-11-25
Granted: 2004-02-03
Abstract: The present invention relates to the field of data and computer network security. Data and computer network security is of the utmost importance to most organisations that possess such networks. One of the difficulties that users and managers of these networks face is that the users have to provide a user ID and password every time they wish to access one of the organisation's secured HTTP servers or URLs. This creates a problem for users and managers since lists of numerous user IDs and passwords need to be maintained and therefore can easily be lost or their confidentiality compromised. This invention addresses these problems by providing a transparent, scalable, single point of authentication for remote users across any number of HTTP servers anywhere on a data network, such as an Intranet, using any user ID and password scheme implemented by a main authentication HTTP server.

Abstract: L'invention concerne l'utilisation de matériaux alvéolaires à des fins d'isolation. Ces mousses polymères sont obtenues par polymérisation de certaines émulsions eau dans l'huile dont le rapport de la phase aqueuse à la phase huileuse est relativement élevé, connues de manière générale sous la dénomination d'émulsions à phase interne élevée ou "HIPEs". Les matériaux alvéolaires dérivés d'HIPE utilisés dans cette invention comportent une structure alvéolaire polymère non ionique d'alvéoles ouvertes interconnectées, qui est de manière générale hydrophobe, souple, semi-flexible ou rigide. Ces structures alvéolaires comportent: A) une aire de surface spécifique par volume de mousse d'au moins approximativement 0,01 m?2¿/cc, B) une masse volumique inférieure à approximativement 0,05 g/cc, et C) une température de transition vitreuse (Tg) comprise entre -20· et 90 ·C. Ces mousses s'utilisent comme matériaux isolants thermiques, phoniques et/ou mécaniques. Dans un mode préféré de réalisation, les mousses utilisées peuvent être préparées, emballées et transportées, comprimées, à haute densité et reviennent à leur densité initiale, dès qu'elles sont activées (par ex. sous l'effet de la chaleur).

Abstract: Cette invention porte sur la démodulation d'un signal dans un système à accès multiple par spectre dispersé mettant en oeuvre une onde pilote sur une liaison aller. Le récepteur en râteau sépare le traitement de signal en fonction de la période pendant laquelle survient le traitement. Le traitement du taux de modulation est réalisé par un seul chemin de données (34) MAC en temps partagé qui dessert des circuits d'entrées à doigts de démodulation multiples (312) et un circuit d'entrée d'exploration (314). Les circuits d'entrée (312) sont des circuits spécialisés qui exécutent tous les traitements de débit des éléments, produisant un vecteur de données et affichant un fanion indiquant que les résultats sont prêts à être exploités par le chemin de données partagé.  Une unité de commande de chemin de données (308) arbitre l'utilisation du chemin de données entre les circuits d'entrées à doigts de démodulation multiples (312), le circuit d'entrée d'exploration (314) et des fonctions de combinaison, configurant le chemin de données pour qu'il les desserve selon le principe du premier arrivé, premier servi. L'unité de commande (308) met en ordre le chemin de données au moyen d'une routine fixe comme prescrit par le traitement de signal associé au bloc desservi.

Title: Slave cylinder stabilizer for harvester header
Inventor: O'HALLORAN MICHAEL
IPC: A01D41/14
Filed: 1998-05-27
Granted: 2002-04-09
Abstract: The windrower or other harvester has a hydraulic lift circuit for its header that includes a pair of double-acting cylinders which operate in concert to raise the header and provide a solid, lower limit for downward swinging of the header. The two cylinders are connected to one another in a master-slave relationship, and the slave cylinder has its return line normally blocked by a one-way check valve so that a body of fluid is trapped against the piston of the slave cylinder during field operations. This stabilizes the two cylinders to reduce header bounce.

Title: Laser-imageable recording constructions utilizing controlled, self-propagating exothermic chemical reaction mechanisms
Inventor: ELLIS ERNEST W
IPC: B41C1/10

Title: Transit vehicle door system
Inventor: BOWEN SCOTT N
IPC: E05D15/32
Filed: 1998-10-05
Granted: 2003-12-30
Abstract: The invention provides a door system for a transit vehicle. It has an actuator which provides a rotary motion about an axis of the actuator for moving the door panel between an open position uncovering the aperture and a closed unlocked position covering the aperture. The actuator also provides a linear motion along the axis of the actuator for moving the door panel between the closed unlocked position and a closed locked position. The rotary motion followed by the axial motion is provided by a cylinder having a piston moved by fluid pressure. The piston includes a guide track in its exterior which engages rollers in the cylinder. The guide track has one portion curving around the piston and one portion parallel to the axis. The curving part provides the rotary motion and the straight part provides the axial motion. When the rotary motion is completed the piston encounters a stop on a shaft which supports the door. The actuator then moves the door axially to engage locks.

Filed: 1997-07-03
Granted: 2008-09-23
Abstract: A direct sequence spread spectrum receiver samples an incoming signal and translates the signal to an IF signal. The IF signal is sampled ans stored in memory (192, 194). In one embodiment, the memory consists of two memory banks which alternately receive sample segments. During a write period to one of the memory banks, the other memory bank supplies its output to a processor (70). This continues in a ping-pong manner. In another embodiment, a single memory bank is filled and read as necessary, the receiver ignoring incoming signal until the processor has completed processing the sample available at the output of the memory. Such a receiver is useful in global positioning satellite (GPS) signal processing where the incoming signal contains several satellite transmissions encoded with CDMA encoding.

Granted: 2004-09-28
Abstract: An apparatus and method reduce out-of-band frequency components of an amplified, multichannel RF signal able to have at least two frequency bandwidth limited signal channels, each channel having a respective carrier frequency which is not known in advance. The channels can, for example, be dedicated to CDMA signals. Each channel of the amplified RF signal has both in-band frequency components and out-of-band frequency components. The apparatus and method feature a network for amplifying an input signal for producing the amplified RF signal, the network having adjustable electrical characteristics, and a control system connected to the network for locating a frequency within the bandwidth of one of the channels of the amplified RF signal and for detecting energy in the out-of-band frequency components for the one located channel for producing control signals relating to the energy in that one channel. As a result of adjusting the electrical characteristics of the network, the energy in the out-of- band frequency components for that channel, and all other channels of interest, can be reduced.
