  • Patent number: 11483303
    Abstract: Provided are a blockchain-based one ID service system and method, in an authentication method according to the embodiment of present invention, an authentication support server maps and registers a first ID issued by a first SP server to a first user and a first site of the first SP server, which is an issuing server, and, upon receiving the first ID from a second SP server, the authentication support server returns information on the first site mapped to the first ID to the second SP server. To this end, there is no need for a separate server configuration to perform an authentication procedure, and it is possible to lessen the burden of performing authentication for SPs.

  • Patent number: 11295976
    Abstract: A substrate support device includes a blade and at least one pad provided on the blade to support a substrate. The pad includes a first fixed member, a second fixed member, and a bridge. The first fixed member is provided at an outer portion of the blade. The outer portion is located outside an outer circumference portion of the substrate when the substrate is supported on the pad. The second fixed member is provided at an inner portion of the blade. The inner portion is under the substrate when the substrate is supported on the pad. The bridge is flexible and connects the first fixed member and the second fixed member to support the outer circumference portion of the substrate. An upper surface of the bridge is inclined downward from the first fixed member toward the second fixed member when the substrate is not supported on the pad.

  • Patent number: 10928575
    Abstract: A display couples a display panel over a light guide plate in a sharp edge housing by adapting the light guide plate side to have a beveled surface that fits along its perimeter into a reduced depth of the housing. The light guide plate beveled surface has angled sides relative to the light guide plate illumination side and reflective side to fit against parallel sides formed in the housing as the housing narrows towards its base where the light guide plate couples. A diffusive pattern formed in the light guide plate reflective surface that directs light towards the illumination surface extends onto the light guide plate side beveled surface.
