    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.

    Abstract translation: LPM搜索引擎包括多个精确匹配（EXM）引擎和中等大小的TCAM。 每个EXM引擎使用前缀位图方案，允许EXM引擎涵盖多个连续的前缀长度。 因此，代替覆盖每个EXM引擎的一个前缀长度L，例如，前缀位图方案使每个EXM引擎能够覆盖具有前缀长度为L，L + 1，L + 2和L + 3的条目。 因此，较少的EXM引擎潜在地未充分利用，这有效地减少了量化损失。 当使用前缀位图方案时，每个EXM引擎提供具有确定的固定延迟的搜索结果。 多个EXM引擎和中等大小的TCAM的结果被组合以提供单个搜索结果，代表最长的前缀匹配。 在一个实施例中，LPM搜索引擎支持32位IPv4（或128位IPv6）搜索密钥，每个具有关联的15位3级VPN标识值。

    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.

    Abstract: A memory system including a content addressable memory (CAM) array and a non-CAM array. The non-CAM array, which may share word lines with the CAM array, stores one or more error detection bits associated with each row of the CAM array. A state machine reads entries of the CAM array and corresponding error detection bits of the non-CAM array during idle cycles of the CAM array. Error detection logic identifies errors in the entries read from CAM array (using the retrieved error detection bits). If these errors are correctable, the error detection logic corrects the entry, and writes the corrected entry back to the CAM array (an updated set of error detection bits are also written to the non-CAM array). If these errors are not correctable, an interrupt is generated, which causes correct data to be retrieved from a shadow copy of the CAM array.

    Abstract: Disclosed is an optical sensing device, which comprises a light source emitting a light; a beam splitter; an SPR sensor unit comprising a sensing surface; and a detecting mechanism; and a converting unit converting the first beam and the second beam from the optical device into a two-dimensional interference fringe pattern. From the above-mentioned configuration, an extra phase shift of a detection beam in SPR phase measurement is obtained. The differential measurement approach has shown to achieve a sensitivity figure significantly better than the best result that can be obtained from the prior art in the field of the measurement based on an SPR sensor.
