Myoung-Hoon Kwak has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11962321
    Abstract: There is provided an analog-stochastic converter for converting an analog voltage signal into a pulse signal having a corresponding probability. The analog-stochastic converter is implemented using a threshold switching element and a simple logic circuit, thereby reducing a size of the analog-stochastic converter and enabling a low power operation thereof. In addition, in order to update a weight, instead of an analog signal, a probability signal is applied using the above-described analog-stochastic converter, thereby updating a weight in a fully-parallel manner in a synaptic element array having an intersection structure. Accordingly, it is possible to shorten a time for weight update.

  • Publication number: 20120026159
    Abstract: An active-type stereographic image display apparatus includes an image display unit; a touch sensing unit to sense a touch position through a first transparent electrode layer and a second transparent electrode layer that are arranged to cross with each other, and to separate an image output from the image display unit through a lens array into a first eye image and a second eye image based on a refractive index of light; and a lens driving control unit to control a focal length by controlling the lens array. The method for driving the active-type stereographic image includes displaying a stereographic image comprising a first eye image and a separate second eye image, sensing a touch position of a user input, separating an image output into a first eye image and a second eye image, and controlling a focal length provided by a lens array.

  • Publication number: 20120026112
    Abstract: Provided are a stereographic image display apparatus and a manufacturing method thereof. The stereographic image display apparatus includes an image display unit and a touch sensing unit which is positioned on the image display unit and is configured to interpose a lens array between a first transparent electrode layer and a second transparent electrode layer. The manufacturing method of the stereographic image display apparatus includes: allowing a transparent conductive material to be deposited on both surfaces of a lens array; forming first and second transparent electrode layers by etching the transparent conductive material deposited on the both surfaces of the lens array thereby generating a touch sensing unit; and adhering the touch sensing unit to an upper surface of an image display unit.

  • Publication number: 20110079499
    Abstract: A dome sheet structure of a mobile communication terminal may include: a metal dome covering a contact point printed on a printed circuit board; and a light guide film disposed on the metal dome. The light guide film may be bonded with the metal dome in a bonding area, and the bonding area may be an area between two concentric circles having different diameters and centered at a center of the metal dome.

  • Publication number: 20040189851
    Abstract: The present invention relates generally to a camera rotation drive module of a mobile terminal equipped with a camera. More particularly, the present invention relates to a camera rotation drive module of a mobile terminal equipped with a camera, which allows a user to push an external button of the mobile terminal to drive a motor and rotate the camera by the driven motor, and which senses an exact position of the camera by a sensor to stop the camera at a predetermined position.
