20120162060 | LASER NAVIGATION MODULE - Disclosed herein is a laser navigation module, including: a light source radiating a laser beam; a housing provided with a window transmitting and reflecting the laser beam radiated from the light source and shielding the introduction of visible rays and provided with a transparent part or a translucent part to radiate light radiated from the inside thereof to the outside; a lighting device mounted in the housing; and a light diffusing member transferring the light radiated from the lighting device and having a groove part formed at an edge of an opposite side of the lighting device. | 06-28-2012 |
20130133426 | INERTIAL SENSOR - Disclosed herein is an inertial sensor including: a membrane; a mass body provided under the membrane; a plurality of patterned magnets provided under the mass body; and a magnetoresistive element provided to be spaced apart from the mass body and measuring static DC acceleration acting on the mass body through resistance changed according to magnetic fields of the plurality of patterned magnets. The plurality of patterned magnets and the magnetoresistive element are included, thereby making it possible to measure static DC acceleration (particularly, gravity acceleration) that is difficult to measure using an existing to piezoelectric element. | 05-30-2013 |
20130220015 | INERTIAL SENSOR - Disclosed herein is an inertial sensor including: a membrane; first and second driving units provided in a first axis direction (an X axis direction) so as to be symmetrical to each other based on a predetermined point of the membrane to thereby vibrate while being expanded and contracted in the first axis direction; and third and fourth driving units provided in a second axis direction (a Y axis direction) perpendicular to the first axis direction so as to be symmetrical to each other based on a predetermined point of the membrane to thereby vibrate while being expanded and contracted in the second axis direction, wherein the first and second driving units have different vibration frequencies so that they vibrate while being expanded and contracted in the opposite manner and then vibrate while being expanded and contracted in the same manner. | 08-29-2013 |
20130255376 | INERTIAL SENSOR AND MEASURING METHOD FOR MEASURING ANGULAR VELOCITY USING THE SAME - Disclosed herein is an inertial sensor. The inertial sensor according to a preferred embodiment of the present invention includes: a plate-shaped membrane; a mass body provided under the membrane; posts provided under an outside edge of the membrane and surrounding the mass body; a piezoelectric body formed on the membrane; sensing electrodes formed on the piezoelectric body; driving electrodes formed on an outer circumference of the sensing electrodes, wherein tri-axis angular velocity can be measured without time division by a driving control unit continuously applying first driving voltage and second driving voltage that are is AC driving voltage having a phase difference of 90°. | 10-03-2013 |
20130320793 | SPINDLE MOTOR - Disclosed herein is a spindle motor including: a shaft forming the center of rotation of the motor; a sleeve receiving the shaft therein and rotatably supporting the shaft; a thrust plate press-fitted into the shaft so as to be perpendicular to an axial direction of the shaft; and a sealing cap spaced apart from the thrust plate in an upward axial direction and bent to enclose an outer side surface of the sleeve to thereby be coupled to the thrust plate, wherein the sealing cap is provided with a sealing part having concave parts and convex parts alternately formed along an inner peripheral surface thereof in a radial direction. | 12-05-2013 |
20140055380 | TOUCH PANEL - Disclosed herein is a touch panel including an electrode pattern formed by forming imaginary lattices configured of same polygons as each other, randomly generating predetermined points in the polygons, and connecting the predetermined points and vertexes of the polygons to each other. The electrode pattern is irregularly formed, thereby making it possible to prevent a Moire phenomenon and improve visibility. | 02-27-2014 |
20140062901 | TOUCH PANEL - Disclosed herein is a touch panel, including: an electrode formed in a pattern including rectangles arranged while sharing sides, the rectangle includes a first side and a second side which are parallel and a third side and a fourth side which are parallel, the first side being longer than the third side, and in the rectangles, among the rectangles, a first side of a first rectangle and a third side of a second rectangle form a straight angle, a first side of the third rectangle and a third side of a fourth rectangle form the straight angle, and a first side of the second rectangle and a fourth side of the third rectangle form the straight angle. | 03-06-2014 |
20140062902 | TOUCH PANEL - Disclosed herein is a touch panel, including an electrode formed in a pattern including continuous rectangles, and in first rectangles which are continuous in a first direction among the rectangles, first common sides and second common sides are alternately formed among the first rectangles, in second rectangles which are continuous in a second direction among the rectangles, third common sides and fourth common sides are alternately formed among the second rectangles, and the first common sides, the second common sides, the third common sides, and the fourth common sides are parallel to each other and have the same length as each other. | 03-06-2014 |
20140083758 | MAGNETIC BOARD AND METHOD FOR MANUFACTURING THE SAME - Disclosed herein is a magnetic board including a composite film including a rigidity film and a ductility film, and a magnetic sheet attached to one surface of the composite film and having fracture lines formed on portions joined with the ductility film. | 03-27-2014 |
