Patent CA-2338085-C (CA)

IPC: H04Q3/66
Filed: 1999-03-16
Granted: 2004-02-17
Abstract: When a subscriber calls into its Internet Service Provider (ISP), a central office receiving the call is triggered to perform a Local Number Portability (LNP) query. This LNP query is sent to an Intelligent Traffic Routing and Control (INTRAC) unit resident on a Service Control Point (SCP) which determines whether the call is to an ISP. If the call is to an ISP, the INTRAC unit polls a Remote Authentication Dial-In User Service (RADIUS) server to determine whether resources are available. The RADIUS server tracks the resources of the ISP and of other ISPs and informs the SCP of the available resources. The SCP then inserts the Local Routing Number (LRN) of the preferred resource into a reply that is sent to the central office. If resources are not available, the call is terminated before signaling occurs with any switch associated with the ISP. On the other hand, when resources are available, the subscriber can be directed to the preferred resource for the subscriber. The subscriber, for instance, can be directed to an access server within the ISP that has excess capacity or can be directed to an access server that provides the best service for the subscriber, whereby subscribers can be directed to X2 type service if they have an X2 modem or to K56Flex type service if they have a K56Flex modem. As another example, if one ISP is at maximum capacity, the subscriber can be directed to a second back-up ISP.

Granted: 2006-01-31
Abstract: A mechanism for use in latching a pivotable access door of a cabinet includes a latch housing within which is rotatably mounted a catch member between latching and unlatching positions upon a carrier which, in turn, is rotatably supported in the latch housing. The carrier is biased into engagement with a cam pin which acts as a pivot stop for the carrier. A cross pin extends through a pair of laterally spaced slots formed in the latch housing and terminal ends of the cross pin are adapted to depress electronic switches through movement of the carrier when the latching mechanism assumes the latched position. The catch member is rotated to the latching position upon engagement with a latch striker and can be rotated to release the latch striker, in accordance with various embodiments of the invention, either through the use of a handle or upon tugging on the access door.

Abstract: The present invention concerns a method and an apparatus for defrosting frozen wood prior to debarking. The defrosting method of logs of the invention is based on bringing heat zone-specifically to logs in transfer motion on a conveyor according to their heat receiving capacity immediately from the moment of starting of the defrosting, and at the end of the defrosting process, the heat volume per time unit, supplied at a higher temperature, is only a part of the heat volume of the starting phase of the defrosting process. For instance, it is possible to spray water on the wood to be defrosted so that the row interval of the showers in the initial part of the piping is a fraction of the row interval in the tail end of the piping. In the tail end of the defrosting conveyor steam can also be supplied.

Abstract: A magnetically guided catheter (210) with sensor (256) provides a permanent magnet (34), and a sensor, both in the distal end portion of the catheter. T he sensor is responsive to the presence of a magnetic field of predetermined strength supplied by an external magnet. The external magnet forms a magneti c coupling with the catheter magnet to permit manipulation of the catheter in response to movement of the external magnet. The sensor responds to the magnetic field of the external magnet, but only when the external magnet, an d the catheter magnet are magnetically coupled sufficiently to create a tracti on force so that the catheter distal end portion can be manipulated by the movement of the external magnet. The apparatus for creating a magnetic guidance path for a remote device includes a follower magnet (12), a sensor, both of which are attached to the remote device, and a leader magnet (34). T he leader magnet forms a magnetic guidance path by permeating the location of t he remote device to form a magnetic coupling between the leader magnet, and the follower magnet. The sensor responds to the magnetic field provided by the leader magnet only when the leader magnet, and the follower magnet are magnetically coupled sufficiently to permit manipulation of the follower magnet by movement of the leader magnet.
