  • Publication number: 20060292367
    Abstract: The present invention relates to an anti-slip agent having a sufficiently large adhesion strength while being easily peeled off, that is, an anti-slip agent having a much larger resistance to the external force applied along the adhesion surface than to the external force applied perpendicular to the surface. The anti-slip agent of the present invention comprises 10 to 40 wt % of a volatile solvent, 1 to 5 wt % of a crystallization inhibitor, 1 to 10 wt % of a humectant, 0.5 to 5 wt % of a preservative, 0.1 to 1 wt % of a leveling agent, 1 to 10 wt % of a viscosity modifier and a biodegradable polymer material as residual.

  • Publication number: 20050094901
    Abstract: A method and apparatus for searching, browsing and summarizing moving image data using the fidelity of a tree-structured moving image hierarchy, which can partition or divide the moving image data into predetermined units, extract a key frame or representative frame from each of the partitioned or divided units, create a tree-structured key frame hierarchy on the basis of the extracted key frames, store a fidelity value of each of the key frames, which is a sub-tree information representative degree of each key frame, at an edge between adjacent ones of the key frames, and effectively and efficiently search, browse and summarize the moving image data using the stored fidelity values. Therefore, a query image or video clip desired by a user can more rapidly and accurately be searched for.

  • Patent number: 6256488
    Abstract: A method for processing a dialed signal in a WLL terminal. Upon sensing of an off-hook state of a telephone connected by wires to a WLL terminal, a DTMF signal corresponding to a key input from the telephone is generated and it is converted into a digital signal. If the digital signal is not a predefined specific key, the digital signal is stored in a dial buffer. If the digital signal is a predefined specific key, the DTMF signal corresponding to the digital signal stored in the dial buffer is sequentially generated to be radio-transmitted.
