  • Patent number: 10880330
    Abstract: System and method for detecting an infected website are disclosed. A semantic finder receives top-level domains and identifies keywords of the top-level domains representing a predetermined semantics. The keywords are compared with irrelevant bad terms to find at least one irrelevant term. An inconsistency searcher searches the top-level domains and detects at least one fully-qualified domain name carrying the at least one irrelevant term. A context analyzer evaluates context information associated with the irrelevant term, identifies at least one frequently-used term identified in the context information, and determines whether the at least one frequently-used term is unrelated to a generic content of the at least one fully-qualified domain name An irrelevant bad term collector extracts the at least one frequently-used term unrelated to the generic content and adds the extracted frequently-used term to an irrelevant bad term list for detecting the infected website.

  • Patent number: 10778120
    Abstract: The present disclosure relates to nanogenerator technology, and discloses a method and a circuit for energy management in a Triboelectric Nanogenerator (TENG), as well as an apparatus including the circuit. The method includes: storing electrical energy outputted from the TENG temporarily in a temporary energy storage; and transferring the electrical energy stored temporarily in the temporary energy storage to an energy storage. With the above solution, the temporary energy storage can be charged and discharged periodically, so as to charge the energy storage. It is possible to achieve impedance match between the TENG and the energy storage and thus a significantly improved energy storage efficiency, such that an AC outputted from the TENG can be converted into a constant-voltage DC output efficiently.
