  • Publication number: 20190297252
    Abstract: A method for implementing animal nose pattern biometric identification system on a mobile device using visual guides displayed on a screen to position a camera in relation to a nose. Suitable types and sizes of visual guides are selected for each animal nose and are superimposed on the perimeter of the nose or features of the nose that are displayed on the screen through the camera. The visual guides help define areas for autofocusing and real-time or post-acquisition image quality assessment, as well as the region of interest used for biometric matching.

  • Publication number: 20190085730
    Abstract: A turbine support structure supports a turbine casing and is configured to be movable when the turbine casing is thermally deformed while a gas turbine is operated, thus preventing a fatigue fracture of the turbine casing from occurring. The turbine support structure includes a pair of supports, each having an upper and lower end, for supporting respective opposite side surfaces of the turbine casing at the upper end of either support; and a movable unit installed at the lower end of each support and configured to movably support the lower end of the support. The movable unit is spaced outwardly from the corresponding opposite side surface of the turbine casing, so that the corresponding support inclines toward the turbine casing and is rotatable. The lower end of each support is rotatably coupled to the corresponding movable unit so that the support is rotatable toward an axis of the turbine casing.

  • Publication number: 20190000742
    Abstract: A cosmetic composition for peel-off-type packs includes a thickener so that pearl or powder particles are stabilized in a formulation to thus impart a sophisticated and differentiated appearance. The content of an alcohol ingredient therein is controlled to accelerate drying, which maximizes a lifting effect. Silicone, imparting a feeling of conditioning, is introduced into polyvinyl alcohol and polyvinyl pyrrolidone, which are film formers, thus minimizing skin irritation upon peeling off.

  • Patent number: 10152792
    Abstract: The present invention relates to a method and apparatus for identifying a living eye, in which IR LED lighting and lighting for varying the ambient illumination are installed on the front surface or one side of an iris recognition camera so as to determine whether an iris of an eye is an iris of a living eye when capturing an iris image by the iris recognition camera, using one or more criteria of whether the ratio of the sizes of the iris and pupil changes by the variation of the ambient illumination, whether the number or location of the IR LEDs focused on the iris and/or the pupil changes, whether the region of the iris image changes by eye blinking, and whether the direction of the gaze changes.
