    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.

    摘要: An apparatus and method for planarizing a surface of a substrate using a chamber separated into two parts by a membrane, and two separate electrolytes is provided. The embodiments of the present invention generally provide an electrochemical mechanical polishing system that reduces the number of defects found on the substrate surface after polishing. An exemplary electrochemical apparatus includes a physical barrier that prevents any trapped gas or gas generated during processing from residing in areas that can cause defects on the substrate. The process can be aided by the addition of various chemical components to the electrolyte that tend to reduce the gas generation at the cathode surface during the ECMP anodic dissolution process.
