Patent CA-2320622-A1 (CA)
Inventor: MARLY NICK
IPC: H04L12/28
Filed: 2000-09-20
Abstract: The present invention relates to a method for connecting a first user-terminal to a second user-terminal over a network such as the Internet. This network contains a plurality of user-terminals and a plurality of network access servers where each of this plurality of user-terminals is coupled to a respective network access server of this plurality of network access servers.      If the second user-terminal connects to its respective network access server, this network access server sends connection information to the subscriber data server. At reception of the connection information the database of the subscriber data server is updated with this connection information.      The subscriber data server handles an incoming call request from a first user-terminal in order to establish a connection between the first user-terminal that is connected to a first virtual private network and the second user-terminal that is connected to a second virtual private network. The subscriber data server at first searches in its database for connection information of the second user-terminal and then determines the respective network access server that is connected to the second user-terminal based on the determined connection information. Then the second user-terminal is notified about the request for communication by the first user-terminal. The second user-terminal initiates and controls a switch-over of the connection of the second user-terminal from the second virtual private network to the first virtual private network.  The respective network access server of the second user-terminal switches the connection of the second user-terminal from the second virtual private network to the first virtual private network. Then at the switch-over of the connection of the second user-terminal from the second virtual private network to the first virtual private network there is also connection information sent by the adjacent respective network access server to the subscriber data server.

Title: Methods and apparatus for characterization, adjustment and optimization of wireless networks
Inventor: HOBBY JOHN D
IPC: H04B7/005
Filed: 2000-10-24
Abstract: Improved techniques for characterizing, adjusting and optimizing the overall performance of a wireless network. In an illustrative embodiment, the overall network performance for a particular network configuration is characterized by a vector with two components, one representing network coverage and another representing network capacity. Network coverage is defined by the likelihood of service under load, including interference, and may be further weighted by traffic density. Network capacity is defined by an amount of traffic with a given spatial distribution that can be served at a given overall target-blocking rate. The overall network performance may be characterized using a two-dimensional capacity/coverage diagram which plots overall network performance vectors, each including a network capacity component and a network coverage component, for various network configurations. The overall network performance may be improved or optimized with respect to a given subset of network parameters by using an algorithm that proposes potential network configurations and evaluates them with respect to their overall network performance.

Title: Systems and methods for delivering drugs to selected locations within the body
Inventor: MACFARLANE K ANGELA
IPC: A61F2/958
Filed: 1999-03-17
Abstract: A trans-vascular system (10) for delivering a drug to a tissue region from a blood vessel, such as a coronary vein, includes a catheter (12) having a distal portion (26) with puncturing (14), orientation (16), drug delivery (62), and imaging elements (18). The puncturing element (14) is deployed for penetrating the vessel wall to access the tissue region. The orientation element (16), e.g., a "cage" including a plurality of struts (38, 40), and/or a radiopaque marker has a predetermined relationship with the location of the orientation element (16) with respect to the tissue region to orient the puncturing element (14). The catheter (12) is percutaneously introducing into the vessel, the puncturing element (14) is oriented towards the tissue region, the puncturing element (14) is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device (230) may also be deployed to create a cavity in the tissue region for receiving the drug therein, or an indwelling catheter (214) may be advanced into, and left in the tissue region. An implanted reservoir device (350) is also disclosed, including an enclosed membrane (354) on an expandable frame (352) that defines a reservoir, and includes a porous region. The reservoir device may be deployed, expanded within a blood vessel, and may be filled in situ or pre-filled with a drug that passes through the porous region. Alternatively, a pair of expandable endovascular blockers may be used to isolate a section of a blood vessel which may be filled with a drug that may be absorbed by the surrounding tissue.

Title: Vehicle navigation system with improved powerup performance
Inventor: SPENCER LARRY E II
IPC: G06F1/32
Filed: 1999-04-02
Abstract: A navigation system includes a driver presence sensor and engine running detection circuitry. When the detection circuitry determines that the engine of the vehicle is not running, the navigation system enters a low power mode. When the presence of the driver is detected, the navigation system begins power up, switching from a low power to a full power operational mode. If the detection circuitry does not determine that the engine is running within a predetermined time period, the navigation system reenters the low power mode. The detection circuitry monitors the vehicle's electrical system and determines that the engine is running when an AC content exceeds a predetermined threshold.

Patent CA-2334319-A1 (CA)
Inventor: KLIMAN GERALD BURT
IPC: H02K17/26
Filed: 1999-06-25
Abstract: Cette invention concerne des rotors (R) à aimants divisés qui font appel à un écart angulaire étagé plutôt qu'à un écart angulaire hélicoïdal. L'écart angulaire étagé permet d'utiliser des sections d'aimant droites (44) que l'on insère dans les encoches (38) du noyau du rotor, ce qui permet d'éliminer tout besoin de formation d'une spirale à partir de la cage du rotor. L'écart angulaire étagé permet de découpler efficacement les harmoniques liées aux encoches du stator. Ce rotor (R) à écart angulaire étagé comprend en outre, dans certains modes de réalisation, des encoches ouvertes (22) qui permettent d'éviter que le rotor ne soit soumis à une saturation de son pont.

Filed: 2001-08-27
Abstract: A method of managing the change of time slot allocation in classical MS-SP  ring networks. In two-fiber rings, the criterion for choosing the low priority AU-4 to be used for the protection in case of simple failure can be summarized as follows: given an STM-n ring line signal, where "n" is the overall number of the handled channels, there results that LP AU-4#X LP = AU-4 #(X HP + n/2), where X is the HP AU-4 index in the failured span. In four-fiber rings, AU-4 LP = AU-4 #X HP.  Should two or more failures occur, criteria are provided for selecting one of the failured spans and tracing the problem back to the case of single two/four fiber ring failure.
