摘要： The present invention relates to a face recognition and/or iris recognition system and method using a mobile device equipped with a stereo camera, which acquire a stereo image of a user's face using at least two cameras or a method corresponding thereto and, even when the size of the stereo image is varied according to distance, correct the size of the stereo image. The stereo camera uses a single-focus lens with a long depth of focus to acquire a focused iris image over a wider range. When the user is not located at a position suitable for iris recognition, a message is sent to the user such that an iris image suitable for recognition is acquired. Furthermore, an iris image correction process according to distance is performed to prevent recognition rate from decreasing even when the size of the iris image is changed.

摘要： Provided is an absorbent for capturing carbon dioxide. The absorbent may include an amino acid with multiple amine groups and an alkali-metal hydroxide mixed with the amino acid and thus, may increase an absorption capacity for carbon dioxide. When a sterically hindered effect is induced to the amino acid with multiple amine groups, the absorption capacity for carbon dioxide may increase and heat of absorption reaction may decrease and thus, energy consumed for regeneration of an absorbent may be reduced. The absorbent for capturing carbon dioxide may include amino acid with multiple amine groups and the metal hydroxide, and may provide a functional group around the amine groups to cause an sterically hindered effect and thus, the absorption capacity for carbon dioxide and an carbon dioxide absorption rate may increase, and the capital cost for a carbon dioxide capturing process and an operating cost may be significantly reduced.

摘要： An iris identification system and method of identifying the identity of an animate being through iris scanning are disclosed. The system features an iris system pick-up unit including a camera for capturing iris images to create input image signals. The iris image pick-up unit is operated with a control unit that is interfaced with a data processing unit for preprocessing the input image signals into processed data. The processed data is representative of one of a plurality of parameters for iris identification selected from the group consisting of (1) the density and texture form of the iris fiber structure using a frequency transformation method, (2) pupilliary reaction, (3) the shape of the pupil, (4) autonomous nervous wreath reaction, (5) shape of the autonomous nervous wreath, (6) the existence of lacuna, (7) the location of the lacuna, and (8) the shape of the lacuna. The control unit is operable to compare processed data with parameters pre-stored in a data base that correspond to the processed data parameters to determine a match indicative of a confirmation of identity.
