Abstract: The present invention relates to a cooling fan including a cooling device that directly transfers heat from a heat source to a rotating fan blade and implements direct cooling by a convective contact between a surface of a rotating fan blade and air in the atmosphere, without fixed heat dissipating fins. The present invention relates to a cooling fan using a surface cooling effect for a rotating fan blade part, including: a heat source part; a heat dissipating plate part installed on the heat source part; a coolant circulating pipe part for moving a coolant in a heat dissipating plate when the heat dissipating plate part uses the coolant to dissipate heat; a rotating fan blade part configured at a position at which the coolant flows in order to forcibly cool the coolant; and a driving part for rotating the rotating fan blade part.

Abstract: A transparent LED wafer module and a method for manufacturing the same are provided. In a conductor LED device epitaxial process, the conductor LED device is grown on a transparent material wafer, where both surfaces of the conductor LED device are entirely grown on the transparent material, and then a transparent glass substrate is restacked, thereby securing a high amount of light.

Abstract: An iris identification system for confirming identity of a person and method thereof are disclosed. The iris identification system comprises a mode converter for selecting one of registration and identification modes, an image input means, a luminance adjustment module, a registration module, an identification module, a reference iris image storage, and a main control unit. The registration module captures iris images when the registration mode is selected, preprocesses the captured iris image, defines the preprocessed iris image as main, auxiliary, negative main and compensation data, encodes the defined data, and registers the encoded data as data of the reference iris images; The identification module captures an iris image when the identification mode is selected, preprocesses the captured iris image, defines the preprocessed iris image as main, auxiliary, negative main and compensation data, encodes the defined data, and analyzes similarity both data.
