Abstract: This invention is a stent graft (2) including a stent member (6) having an inner surface and an outer surface, a generally tubular graft member (4) and a coupling member (8) that couples the stent member (6) to the graft member (4). The coupling member (8), which in the preferred embodiment is in the form of a ribbon, covers only a portion of the inner or outer surface of the stent member (6) and secures the stent member (6) and graft member (4) to one another. Alternatively, the coupling member (8) can be described as interconnecting less than entirely the inner or outer surface of the graft member (4) to the stent member (6). With this construction, regions of the stem member (6) do not interface with the coupling member (8). Shear stresses between the stent member (6} and the coupling member (8) and the risk of tearing the graft (4) or coupling member (8) or delamination therebetween may he reduced as compared to a fully enveloped stent member (6). This construction also provides improved flexibility and kink resistance.

Abstract: Cette invention concerne un répéteur qui va n'entraîner qu'un retard minimal lors du transfert d'un paquet de données depuis un réseau local source vers un réseau local de destination. Ce répéteur comprend un arbitre qui va garantir l'accès d'un port à un bus, ceci afin de diffuser un paquet de données reçu sur le bus, et de charger le paquet de données dans un tampon émetteur pour chaque port sortant. Cet arbitre garantit l'accès uniquement lorsque tous les ports ont signalé que leurs tampons émetteurs sont prêts à charger le paquet de données provenant du bus. Un tampon émetteur signale qu'il est prêt à être chargé lorsque passe la fenêtre de collision et qu'il transmet un paquet préalablement chargé dans le tampon émetteur. Le tampon émetteur va ainsi simultanément transmettre le paquet préalablement chargé, et charger le nouveau paquet une fois que l'arbitre a répondu au signal.
