  • Publication number: 20250017495
    Abstract: An authentication device includes an image acquisition unit, an identification unit, and an authentication unit. The image acquisition unit acquires an image of an eye of a subject. The identification unit identifies the colored pattern of a colored contact lens worn by the subject by comparing a reference image with the image of the eye. The authentication unit identifies the subject, using a feature in a region other than a colored region of the colored pattern in the iris region of the eye.

  • Patent number: 10092048
    Abstract: The present invention embodies a garment which can smoothen motions of its wearer by a new technique, which is totally different from that of exerting a tightening force on a muscle, according to findings that the range of motion of a joint can be widened if a structure for extending and gathering respective parts of a skin gathering and leaving when the joint works in relation to bending/extension or abduction/adduction of the wearer is added to the garment and that the range of motion of the joint can be widened if a structure for moving the skin along a direction of motion of a muscle when the joint works in relation to turning of the wearer is added to the garment, on the basis of a close relationship between a motion of the skin when the joint works and an extending direction of a tension line.

  • Patent number: 9642401
    Abstract: On the front side of the main part, the first start part separates the main part into a portion covering a knee joint of a wearer and a portion covering at least one of femoral and shin parts of the wearer. On the back side of the main part, the second start part separates the main part into a portion covering the knee joint of the wearer and a portion covering at least one of the femoral and shin parts of the wearer. On an outer side face side of the main part, the third start part at least partly extends under the portion covering the knee joint of the wearer. On an inner side face side of the main part, the fourth start part at least partly extends downward in a part lower than a crotch part of the wearer.
