  • Publication number: 20120025340
    Abstract: The vertical silicon photomultiplier according to the present invention includes a trench electrode and a PN-junction layer perpendicular to the trench electrode forms and can maximize the quantum efficiency at optical wavelengths, 200˜900 nm in such a way that: it generates electric fields horizontal thereto, by applying a reverse bias voltage to between the trench electrode and the PN junction layer, so that, although ultraviolet light does not reach the PN-junction layer but is incident on the surface, electron-hole pairs can be produced by the horizontally generated electric fields although and an avalanche breakdown can be thus generated, and it allows ultraviolet light, capable of being transmitted to a relatively deep depth, to react with the PN-junction layer.

  • Publication number: 20110219010
    Abstract: The present disclosure provides an apparatus and method for packet classification using a Bloom filter and includes determining a matching length of how long each field value of one or more fields in an input packet coincides with a field value of the corresponding field stored in a rule set by performing a field-by-field search on the fields in the input packet, and generating a tuple list made up of a combination of one or more of the matching length for the respective fields; selecting particular tuples existing in the rule set from the tuple list; filtering each of the selected tuples by using the Bloom filter; and searching for a best matching rule as a search pool exclusively within the tuples with the positive result of the filtering. According to the present disclosure, the object tuples to search can be substantially relieved to improve the searching performance.
