Abstract: L'invention concerne un procédé servant à distribuer les itinéraires afin d'optimiser les services multiples d'un réseau de transmission SDH. Ce procédé consiste à : a) diviser le réseau de transmission en réseau secondaire selon des anneaux et calculer l'itinéraire original en fonction des besoins du service dans le réseau de transmission ; b) estimer séparément si les ressources de liaison des réseaux secondaires entre les anneaux et à l'intérieur des anneaux sont surchargées et, si c'est le cas, recalculer l'itinéraire de transmission ; c) décider si le réseau secondaire annulaire répond aux besoins d'équilibrage de charge et, dans le cas contraire, ajuster l'itinéraire de transmission ; d) évaluer si l'indice d'intégration du réseau secondaire central répond à la condition de convergence après division de ce réseau secondaire en réseau secondaire périphérique et en réseau secondaire central et, dans le cas contraire, évaluer si le temps de calcul d'itinéraire atteint le seuil, puis, dans un cas positif, mettre fin au processus de distribution d'itinéraire, sinon recalculer l'itinéraire de transmission. Cette invention permet d'améliorer l'efficacité de calcul de distribution d'itinéraire dans un réseau à grande échelle, tout en faisant appel à moins de ressources du réseau et, simultanément, optimisant l'équilibrage de charge du réseau.

Abstract: L'invention concerne lors de la production d'un laminé à partir de couches métalliques (7) et de couches de liaison en plastique renforcées par des fibres (8), un bloc (6) est formé puis placé sur un gabarit de formage (1). Un milieu d'évacuation (12) et un film sous vide (13) sont placé par dessus le bloc, de telle sorte que le bloc puisse être pressé contre le gabarit de formage sous l'effet du vide. Enfin, les couches sont liées les unes aux autres dans un autoclave sous l'effet de la chaleur et d'une pression. Plus particulièrement, dans le cas des grosses pièces à usiner, se pose le problème du déplacement des couches les unes par rapport aux autres. Souvent, ce déplacement n'est pas souhaitable et les couches doivent être maintenues dans une position correcte les unes par rapport aux autres. A cette fin, une tige (4) est utilisée; elle est fixe par rapport au gabarit de formage. Les diverses couches présentent des orifices (9), de telle sorte qu'elles peuvent être placées sur le gabarit de formage dans une position correcte par rapport à la tige. Le milieu d'évacuation et le film sous vide sont ensuite déposés sur le haut de la tige, puis le vide est appliqué. Le film sous vide et le milieu d'évacuation sont ensuite découpés, la tige est retirée et le film sous vide est de nouveau scellé. Pendant ce processus, le vide reste pratiquement intact, de cette manière, les couches restent dans la bonne position les unes par rapport aux autres.

Abstract: There is provided a liner for a container that provides a gas and moisture barrier. The liner includes a first sealant web of polyethylene that defines a self-supporting layer of the liner. An adhesive layer is applied to an outer surface of the first sealant web, and a metal foil layer is adhered to the adhesive layer. A second sealant layer is attached to the metal foil layer. The second sealant layer may be heat-sealed to the first sealant web so that when the liner is adhered to the inside surface of a container, the liner may be sealed to itself with a lap seal. The first sealant web defines a self supporting layer because it provides structural support to the liner. Accordingly, the first sealant web advantageously serves as a carrier web for the liner while the liner is being manufactured.

Title: Patient monitoring device with multi-antenna receiver
Inventor: GOEDEKE STEVEN D
IPC: A61B5/00
Filed: 2004-01-27
Abstract: A patient monitoring device incorporates a receiver capable of single-antenna or multi-antenna operation. Multi-antenna operation permits the monitoring device to take advantage of spatial diversity for improved communication with an implantable medical device in the presence of fading. However, the small size of many patient monitoring devices can make the incorporation of multiple antennas difficult. To permit spatial diversity operation, a base station includes at least a second antenna that can be coupled to the patient monitoring device. Alternatively, the base station may have one or more high quality antennas that are used by patient monitoring device instead of the antenna in the patient monitoring device when the patient monitoring device is coupled to the base station.
