An automatic technique for generating signatures for malicious network traffic performs a cluster analysis of known malicious traffic to create a signature in the form of a state machine. The cluster analysis may operate on semantically tagged data collected by connection or session and normalized to eliminate protocol specific features. The signature extractor may generalize the finite-state machine signatures to match network traffic not previously observed.

The present invention relates to an apparatus and a method for performing power calibration in a wireless power transmission system. The present specification provides a wireless power transmission apparatus comprising: a power conversion unit configured to transmit, in a power transfer phase, wireless power generated on the basis of magnetic coupling to a wireless power receiving device; and a communication / control unit configured to perform an initial calibration for a power parameter prior to the power transfer phase, receive a first received power packet from the wireless power receiving device indicating the power received by the wireless power receiving device during the power transfer phase, and detect foreign matter by using the received power and a first power loss determined on the basis of the initial calibration. It is possible to adaptively respond to a newly changed wireless charging environment to calibrate transmission power and reception power, and it is possible to detect foreign matter more precisely by detecting a power loss on the basis of the calibrated transmission and reception power.

The present invention provides a moisture detection sensor, a defect detection sensor, and a sensor array using the same, the moisture detector sensor comprising at least one moisture sensitive compound selected from the group consisting of Calcein, Calcein acetoxymethyl ester, Calcein-AM and Calcein blue. The moisture detection sensor and the defect detection sensor of the present invention have excellent selectivity, thereby being able to accurately quantify only moisture without being influenced by a coexisting gas, and are reversible so that the moisture detection sensor and the defect detection sensor can be re-used continuously, whereby it possible to reduce costs required and effectively monitor changes in moisture concentration. As such, the moisture detection sensor and the defect detection sensor can measure moisture barrier properties or water vapor transmission properties. In addition, the moisture detection sensor and the defect detection sensor have advantages of accurately detecting moisture due to excellent sensitivity and being very fast in response speed. Further, the present invention can easily monitor defects by utilizing the phenomenon whereby moisture easily penetrates into the defect detection sensor through a defect and thus fluorescence intensity increases.
