Title: Dispositifs de chirurgie et des procedes s'utilisant dans des procedures d'ablation de tissus
Inventor: REEVE LORRAINE E
IPC: A61B18/14
Filed: 2001-02-09
Abstract: L'invention concerne des dispositifs et un procédé destinés à assister un chirurgien lors de l'ablation de chemins conducteurs dans les tissus, notamment le coeur. Un dispositif peut être conçu de manière à agir en tant que gabarit adhérant à la surface des tissus, et permet au chirurgien de couper plus facilement le chemin conducteur en vue de former une lésion au niveau d'un emplacement désiré. Le gabarit peut notamment être utilisé afin de guider un chirurgien dans l'utilisation d'un instrument de chirurgie le long d'un chemin d'ablation désiré. Dans certains cas, le gabarit peut comporter un matériau qui supporte de façon structurelle l'instrument lorsqu'il se déplace le long du chemin d'ablation. Un instrument de chirurgie, tel qu'une sonde d'ablation, à savoir, une sonde d'ablation radiofréquence, laser, ultrasonore, hyperfréquence, thermique, chimique, mécanique ou cryogénique, peut être utilisée pour couper les chemins conducteurs. Des mesures établies sensiblement en même temps que l'opération d'ablation de du chemin conducteur peuvent être utilisées afin d'évaluer si le degré désiré d'ablation a été atteint. Le dispositif peut également inclure la rétroaction afin de comparer le degré désiré d'ablation du chemin conducteur avec le degré mesuré, et peut désactiver l'instrument de chirurgie lorsque le degré désiré est atteint. Dans certains cas, le gabarit peut être conçu de manière à assurer une stabilisation locale des tissus d'organe, en particulier pour un organe mobile tel qu'un coeur palpitant. Dans d'autres cas, le gabarit ne peut assurer qu'une faible stabilisation ou pas de stabilisation du tout, mais il fournit une structure guide destinée au déplacement de la sonde d'ablation dans une même proportion que celui des tissus mobiles. De même, dans certaines applications, le gabarit peut être positionné de manière à faciliter l'application d'autres dispositifs thérapeutiques, tels que des sondes diagnostics, des sondes de pacemaker, et des dispositifs de distribution de médicaments, à la surface d'un organe mobile.

Title: System and method for adjusting pcm data frames for robbed bit signaling in a telephone network
Inventor: PILOZZI JOHN
IPC: H04L25/49
Filed: 2001-02-01
Abstract: A system and method for shifting the relative phases of a PCM data frame and a network RBS frame by one or more symbols is disclosed. The method includes determining whether or not RBS is present (100). If RBS is present, the slots affected by RBS are identifed. Next it is determined what data slots, if any, are affected by encoding (102). The PCM data frame is shifted to the RBS constraint and the encoding constraint do not coincide at any particular data slot (104). For one particular PCM upstream modulation scheme, the digital modem adjusts the relative phases of the data-mode frame and network RBS frame such that a minimum number of trellis-modified symbols fall on network RBS affected slots. This information is transmitted to an analog modem (106).      The amount of shift can be conveyed to an analog modem in the same data sequence used to send upstream constellation sets and mapping parameters during an initial training sequence. The present invention improves the performance of any PCM modem that employs a data frame structure in which not all symbols are subject to the same constraints, for example, due to trellis coding.

Title: Drive roller control for toric-drive transmission
Inventor: CAREAU FERNAND
IPC: F16H61/664
Filed: 2002-09-05
Abstract: A toric-drive transmission comprising a drive disk adapted for receiving a drive input from actuation means. A driven disk is opposite the drive disk and adapted for transmitting motion to output means. Drive rollers are between the drive disk and the driven disk. The drive rollers have three rotational degrees of freedom. A first one of the rotational degrees of freedom is for transmitting motion from the drive disk to the driven disk. A second one of the rotational degrees of freedom changes an input-to- output ratio between the drive disk and the driven disk. A third one of the rotational degrees of freedom initiates rotation about the second one of the rotational degrees of freedom. Control means are provided for controlling motion of the drive rollers in the second and third ones of the rotational degrees of freedom.

Title: Multi-phase adaptive network configuration
Inventor: BESHAI MAGED E
IPC: H04Q3/00
Filed: 2003-03-10
Abstract: The present invention enables fast reconfiguration of paths associated with bufferless core nodes in a network where any two edge nodes may interconnect through a core node. In order to enhance network agility and performance, edge nodes associated with a core node are separated into a plurality of groups based on, for example, round-trip delay from the core node. This separates the short-haul paths from the long haul paths, thereby enabling the short-haul paths to be configured more frequently than the long-haul paths. It is preferable that the periods be set such that each additional period is an integer multiple of the previous one. This allows for simultaneous configuration of groups of paths. Although the methods and apparatus of the present invention are most effective for bufferless optical switches, they are still effective for electronic switches which may be bufferless or equipped with input data buffers.
