Patent CA-2460772-C (CA)

Abstract: La présente invention concerne une architecture donnant un accès haute vitesse par des canaux à multiplexage de fréquences et permettant l'émission de trames Ethernet et/ou l'accès par d'autres données à un réseau de transmission par câble ou une autre forme de transport à multiplexage de fréquences. Cette architecture implique des techniques de multiplexage par répartition de fréquences vers l'aval et l'amont, de façon à permettre des communications simultanées et parallèles utilisant une pluralité de canaux de fréquences. En outre, un contrôle automatique de fréquence (CAF) résout certains problèmes propres à une synchronisation relaxée (4708) dans un syntoniseur amont du concentrateur central du fait de l'exécution de réglages prenant en compte l'erreur de fréquence moyenne de plusieurs fréquences de référence amont actives. Dans les modes de réalisation préférés, la contrôle automatique de fréquence utilise une boucle de rétroaction pour au moins chacune des fréquences de référence amont actives (Fig. 47). De la même façon, on calcule la moyenne des fréquences de référence amont actives et on s'en sert pour fournir la rétroaction servant à régler le contrôle automatique de fréquence (CAF) (Fig. 47).

Abstract: Ancrage osseux (46) et procédés permettant d'attacher des tissus mous tels que des tendons, à un os, ce qui permet une attache par suture se trouvant entièrement sous la surface de la corticale de l'os. Avantageusement, le matériau de suture entre les tissus mous et l'ancrage osseux est maintenu sans qu'il soit nécessaire de faire un noeud. L'attache par suture à l'ancrage osseux (46) est obtenue par la formation d'une boucle de fil de suture autour d'une poulie se trouvant à l'intérieur de l'ancrage osseux, par serrage du fil de suture et des tissus mous attachés et par blocage par serrage du fil de suture à l'intérieur d'un passage contenant une pluralité d'éléments de blocage (62a, 62b) de fil de suture. Les éléments de blocage (62a, 62b) peuvent être minces et en forme de C. Un ou plusieurs bouchons d'obturation (68a, 68b) fixés sur des tiges d'actionnement séparables (70) sont axialement mobiles dans le passage et agissent sur les éléments de blocage (62a, 62b) pour déplacer ces derniers radialement. Un passage généralement uniforme à travers les éléments de blocage (62a, 62b) lorsqu'ils sont dans leur première position se transforme en un passage irrégulier plus petit lorsque les bouchons d'obturation (68a, 68b) déplacent les éléments de blocage (62a, 62b) vers leur seconde position, ce qui provoque un blocage effectif de la suture. Ledit ancrage osseux (46) peut en outre comprendre une structure de blocage (72a, 72b) destinée à fixer l'ancrage osseux dans une cavité osseuse.

Title: System and method for dynamically altering connections in a data processing network
Inventor: FERNANDES LILIAN SYLVIA
IPC: H04L12/66
Filed: 2002-10-28
Granted: 2007-04-03
Abstract: A data processing network and system in which a network connection is enabled to migrate among a multitude of available servers and/or clients to provide the connection using the most efficient available set of resources. Typically a server and client would indicate their respective support of this connection migration feature when the connection is established. An operating system or application program would monitor existing connections for characteristics including basic functionality and performance. If an existing connection were found to be faulty or low performing and the client and sever associated with the connection supported connection migration, the software would then determine if an alternative and more effective connection existed. Upon discovering such a connection, the parameters that define the connection would be altered to migrate the connection to the preferred hardware. In an embodiment in which the network connections are established with a transmission control protocol (TCP), each connection includes a four-tuple that completely defines the connection, namely, a source IP address, a source port number, a destination IP address, and a destination port number. By altering one or more of the connection's defining four-tuple, the invention is configured to migrate the connection to a NIC or system that is functioning more efficiently.

Abstract: A wireless local area network includes multiple access points with overlapping coverage, and modes of different power consumption are available to the access points. It is assessed whether the traffic load of the network may be adequately supported using fewer access points in an active mode. If so, the traffic load is redistributed from certain active access points among the remaining access points in the active mode. The certain access points are switched into a mode of lower power consumption than the active mode. Similarly, it is assessed whether the traffic load of the network is adequately supported by the current number of access points in an active mode. If not, certain access points which are in a mode of lower power consumption are switched to the active mode. The traffic load is redistributed among the access points in the active mode including the certain access points.
