Title: Method and apparatus for bandwidth allocation
Inventor: STANWOOD KENNETH L
IPC: H04L12/56
Filed: 2000-05-19
Granted: 2006-11-21
Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a "polling" method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a "poll-me bit" or, alternatively, it may be periodic. Another technique comprises "piggybacking" bandwidth requests on bandwidth already allocated to a CPE. In accordance with this technique, currently active CPEs request bandwidth using previously unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE. By using a combination of bandwidth allocation techniques, the present invention advantageously makes use of the efficiency benefits associated with each technique.

Abstract: A method for fabricating a piezoelectric macro-fiber composite actuator comprises providing a piezo-electric material (20) which has a first side and a second side. The method further comprises cutting the piezoelectric material to provide a plurality of piezoelectric fibers (26) in juxtaposition. Two electrically conductive films (28, 42) are then adhesively bonded to the two sides of the piezo-electric material. The first film (28) has first and second conductive patterns (30, 32) formed thereon which are electrically isolated from one another and in electrical contact with the piezo-electric material.  The first and second conductive patterns of the first film each have a plurality of electrodes to form a pattern of interdigitated electrodes. In one embodiment, the second film does not have any conductive patterns. In another embodiment, the second film (42) has a pair of conductive patterns (48, 52) similar to the conductive patterns of the first film. In another embodiment, the piezoelectric macro-fiber composite actuator further comprises a pair of anisotropically conductive sheets (210, 212) each positioned between one of the electrically conductive films and one side of the piezoelectric material.

Abstract: La présente invention concerne une méthode de signalisation et un élément de réseau pour réseau privé virtuel selon lesquels une demande d'insertion de signalisation du réseau privé virtuel est transmise d'un élément de réseau (DXD) à un élément de réseau précédent (DXC) s'il apparaît que la signalisation du réseau privé virtuel ne peut pas se poursuivre via une connexion du réseau de télécommunications. A l'aide d'un élément de réseau prédéterminé (DXB), on émet une information de transparence indiquant une transparence de signalisation pour le réseau privé virtuel à un élément de réseau d'origine (DVA) de la connexion, ceci en réponse à la réception de la demande d'insertion, la signalisation du réseau privé virtuel étant recueilli au niveau de l'élément prédéterminé de réseau (DXB). Ainsi, l'opérateur du réseau public peut optimiser la charge de signalisation du réseau privé virtuel et la fourniture de services en disposant l'élément prédéterminé de réseau (DXB) en un point approprié du réseau de transmission.

Granted: 2011-01-04
Abstract: An apparatus for sealing a passage through tissue includes an elongate shaft and a cylindrical plug disposed on a distal end of the shaft, the plug including a helical thread on its outer surface. Intestinal submucosa may be secured to the plus, e.g., in a cavity in its distal end, that may be delivered into the passage. Alternatively, the plug may be formed from a bioabsorbable material and may be released from the shaft within the passage.  The plug is threaded into the passage, thereby engaging the tissue to seal the passage. The shaft is rotated until it engages a blood vessel within the tissue while monitoring blood flow through the vessel. The shaft is rotated to thread the plug into the passage until blood flow ceases through the vessel, whereupon rotation of the shaft is reversed to back the plug until blood flow through the vessel resumes.
