Abstract: Provided is a multi-scale digitizer using a 3D magnetic force sensor and a magnetic force pen, wherein one or more magnetic force sensors are installed inside a recognition device, and a change in a magnetic field of an external input unit with a magnetic material installed therein is measured through the sensors to detect a position of the external input unit. Since the digitizer capable of detecting position information of an external input unit by using the magnetic force sensors installed inside the recognition device is implemented, there is no need to provide a separate digitizer panel, and thus, a display device may be reduced in weight and thickness.

Abstract: A cargo screen device for a vehicle may include a housing unit which has a screen drawing groove, and a screen unit which includes a screen member that may be wound in the housing unit, or deployed from the housing unit through the screen drawing groove, wherein the screen unit includes a wire member which may be made of a flexible material, and coupled to the screen member along a tip of the screen member.

Abstract: A functional styrene-butadiene copolymer is disclosed. More specifically, the copolymer is prepared by radical polymerization of a styrene monomer, a butadiene monomer and an epoxy acrylate monomer in an emulsion state and ring-opening of the resultant styrene-butadiene-epoxy acrylate copolymer. When blended with silica, the disclosed copolymer provides excellent wet stopping performance and superior wear resistance. Therefore, it can be usefully applied for industrial materials including fuel-efficient tires, snow tires, belts, hoses, etc.

Abstract: An isolation structure and method of forming the same. The isolation structure includes a first isolation structure having including an insulation layer formed in a trench in a substrate and a second isolation structure, formed on the first isolation structure. The second isolation structure includes a first impurity region formed in the substrate, the first impurity region having a first impurity doping concentration, and a second impurity region that is formed around the first impurity region, the second impurity region having a second impurity doping concentration that is greater than the first doping concentration.

Abstract: Provided is a touch screen integrated digitizer including a three-axis magnetic force sensor and a magnetic pen, which measures a distribution and a change amount of a magnetic force vector, generated by moving the magnetic pen generating a magnetic force, to accurately sense a position of the magnetic pen which is moved on a touch screen. Since the digitizer for detecting position information of an external input unit is implemented with a magnetic force sensor installed at an internal edge of a display device, a separate digitizer panel is not provided, and thus, the display device is lightened and slimmed.
