  • Patent number: 8880494
    Abstract: A LPM search engine includes a plurality of exact match (EXM) engines and a moderately sized TCAM. Each EXM engine uses a prefix bitmap scheme that allows the EXM engine to cover multiple consecutive prefix lengths. Thus, instead of covering one prefix length L per EXM engine, the prefix bitmap scheme enables each EXM engine to cover entries having prefix lengths of L, L+1, L+2 and L+3, for example. As a result, fewer EXM engines are potentially underutilized, which effectively reduces quantization loss. Each EXM engine provides a search result with a determined fixed latency when using the prefix bitmap scheme. The results of multiple EXM engines and the moderately sized TCAM are combined to provide a single search result, representative of the longest prefix match. In one embodiment, the LPM search engine supports 32-bit IPv4 (or 128-bit IPv6) search keys, each having associated 15-bit level 3 VPN identification values.

  • Publication number: 20140078404
    Abstract: A method and system for automatically adjusting television volume, and a television set or a remote controller are disclosed. In the method and system, it judges whether the environmental sound surrounding the television includes the same sound component with a preset phone ringing, and thereby identifies whether there is an incoming call when the user is watching television, and if there is an incoming call, an operation of reducing television volume is automatically performed, without the user's manual operation of reducing the TV volume. When receiving a call when watching TV, the user does not need to find a remote controller and look for the phone, which brings great convenience for the user. The system can be provided on the television, and can also be provided on a television remote controller or a controller, to automatically adjust the television volume according to the phone ringing.

  • Publication number: 20120156693
    Abstract: A method for generating and localizing a signal in a solid phase substrate detection system comprises applying a solution of target material to a substrate; binding the target with a specific affinity molecule having an attached label, the label comprising multiple signal precursor molecules; applying a carrier to the substrate, and treating the label to convert the signal precursor molecules to signal generating molecules. The carrier comprises solvent for the label and thickener for localizing the signal. The carrier may include developer that converts signal precursor molecules to signal generating molecules. Developer is not necessary if the signal precursor molecules are converted to signal generating molecules by e.g. temperature change, pH change, sonication, light irradiation, microwave heating. A test device for detecting target in a fluid sample, and a kit of parts for determining the presence of target in a fluid sample are also disclosed.
