Abstract: PURPOSE: Automatic focus eyeglasses are provided to improve convenience and to offer a wide viewing angle. CONSTITUTION: Automatic focus eyeglasses include one pair of lenses(200), a focus measurement unit(300), and a focus control unit(400). One pair of lenses is formed in the left side and the right side of an eyeglasses frame. The focus measurement unit measures a focal length by being formed in a specific location of the eyeglasses frame. The focus control unit is connected with a pair of the lenses and the focus measurement unit and controls a focus of the lens according to the measured focal length in the focal length measurement unit.

Abstract: PURPOSE: A location-based authentication system and an authentication method using the same are provided to efficiently prevent the distribution of imitation products by comparing first intrinsic information with first location information stored in an authentication server with each other. CONSTITUTION: A communication module(510) receives first intrinsic information and first location information of products. The communication module receives third location information of a consumer terminal while receiving second intrinsic information and second location information of the products from the consumer terminal. An encoding module(520) encodes the first intrinsic information and the first location information by using an encoding key.

Abstract: PURPOSE: A manufacturing method for separation membrane of asymmetric polyimide is provided, which can increase productivity by rapid soaking polyamic acid solution into non-solvent and also can selectively decide the structure of separation membrane by controlling imidification rate. The manufactured separation membrane is excellent in resistance to solvent and can be used at the temperature that is over the limit temperature of general membrane separation process. CONSTITUTION: The manufacturing method is as follows: (i) prepare separation membrane by heating for partial imidification before impregnating polyamic acid of 15-20 wt.% into non-solvent of water or low-grade alcohol for phase separation; and (ii) imidify at a high temperature to prepare polyamide separation membrane.

Abstract: The connecting matrix between input and output neurons is adjusted to reduce errors between the desired output and the actual output, and the number of adaptive elements are reduced so that large scaled optical implementation is done easily. The optical neural network includes a multi-layer hologram (47) for interconnecting input neurons and output neurons, spatial light modulators (3,8) for providing local adaptive interconnection of neurons, a foward path (1) for adaptive learning, a reverse path (2) for calculating error transmitted reversly, a two dimensional detector (5) for calculating sigmoid function in the output plane, a two-dimensional detector (10), for calculating error in the input stage, and a personal computer (6) for designating strength of local adaptive interconnection of the spatial light modulators (3,8) .
