    摘要: A method and a system for obtaining path information as well as a PCE are disclosed herein. All the PCEs from the source PCE to the confluent PCE compute the shortest path from the source node to the egress border node of the domain covered by the respective PCE one by one, and send the computation result to the next-hop PCE until the confluent PCE. Meanwhile, all the PCEs from the destination PCE to the confluent PCE compute the shortest path from the destination node to the ingress border node of the domain covered by the respective PCE one by one, and send the computation result to the previous-hop PCE until the confluent PCE. After receiving computation results from the previous-hop PCE and the next-hop PCE, the confluent PCE computes the shortest path between the source node and the destination node, and sends the shortest path to the source PCE.

    摘要: High compression rate codecs in gateways servicing Voice-over-Internet Protocol (VoIP) and Voice Band Data (VBD) calls distort modem/fax Answer Back Tones (e.g., 2100 Hz), which may lead to signal distortion and call hang-ups. To prevent such occurrences, a method or corresponding apparatus forces originating and terminating gateways to stay in a low complexity non-voice compression codec (e.g., ITU G.711) after prenegotiating a high complexity, voice compression codec (e.g., G.729 or G.726) during a short beginning period of a voice call. The low complexity codec avoids distorted answer back tone leakage associated with previous solutions that use a notch filter to block the leakage, thereby significantly improving the success rate of a VBD call by completely eliminating modem answer back tone distortion caused by high complexity codecs that use voice compression and by completely eliminating use of the notch filter.

    摘要: A clamping system for clamping aerofoils. The clamping system has pivotally mounted engagement members that engage the aerofoil mounted on a pivotally mounted arm either side of the pivotal mounting. The arm can pivot as required relative to the item, to accommodate differences in shape in the item, whilst providing a substantially equal clamping force by both engagement members.

    摘要: A retaining ring for use with electrochemical mechanical processing is described. The retaining ring has a generally annular body formed with a conductive portion and a non-conductive portion. The non-conductive portion contacts the substrate during polishing. The conductive portion is electrically biased during polishing to reduce the edge effect that tends to occur with conventional electrochemical mechanical processing systems.
