  • Patent number: 10525665
    Abstract: A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.

  • Patent number: 10032288
    Abstract: Provided is a method and system for integrating multiple image markers to generate a single integral image marker for configuring content such as game content. The present invention proposes a method of expressing, in a global coordinate system, feature points for each image marker whose positions are expressed in their local coordinate system by calculating relative positions of the image markers and applying the calculated relative positions to the image makers other than a reference image maker to transform 3D positions of feature points in each image marker.

  • Patent number: 9151752
    Abstract: Provided is a method for amplifying a frequency variation of a detected signal in a biosensor that is used for detecting a biomolecule by measuring a change in frequency of an oscillating signal, the change being caused by pressure a biomolecule applies to a piezoelectric substance. The method for amplifying a frequency variation of a detected signal comprises the steps of: (a) applying a sample to a probe being fixed to an upper portion of a substrate of the biosensor to allow a biomolecule in the sample to be bound to the probe; (b) applying protein tagged with a metal particle to the biosensor to allow the protein and the biomolecule to be bound with each other; and (c) applying a metal enhancer to the biosensor to allow the metal enhancer to be bound to the metal particle having been bound to the protein.

  • Publication number: 20150224402
    Abstract: Disclosed herein is a game bot detection apparatus and method. The game bot detection apparatus delivers a natural language query to a game user and determines whether the game user uses a game bot, based on expression of a response to the natural language query, received from the game user so as to determine whether the game user uses the game bot. The game bot detection apparatus includes a query generation unit for generating a natural language query to be provided to the game user. A keyword extraction unit receives expression of a response to the natural language query, input by the game user, and extracts a keyword from the response expression. An association analysis unit analyzes an association between the natural language query and the keyword, and determines whether the game user uses a game bot, based on results of analysis of the association.
