  • Patent number: 10356666
    Abstract: A module includes a switching request receiving unit configured to receive, when the module is connected with one terminal, a switching request indicating a connection switching to another terminal, an address changing unit configured to change the connection destination address using the reception of the switching request by the switching request receiving unit as a trigger, a connection disconnecting unit configured to forcibly disconnect the connection with the one terminal when the connection destination address is changed by the address changing unit, and a connection process executing unit configured to receive a connection request from the another terminal by the connection destination address changed by the address changing unit after the connection with the one terminal is disconnected by the connection disconnecting unit and to connect with the another terminal.

  • Patent number: 10129030
    Abstract: A wearable device generates a temporary ID, generates an encrypted user ID, and transmits the temporary ID and the encrypted user ID to a shop system. The shop system receives the temporary ID and the encrypted user ID, transmits a temporary ID corresponding to the received temporary ID and the encrypted user ID to a server, and transmits the temporary ID transmitted by an identifier transmission unit and waiting state information to the server. The server stores the user ID in association with an information delivery destination of the user ID, receives the encrypted user ID and the temporary ID, associates the temporary ID and the information delivery destination of the user ID, receives the temporary ID and the waiting state information, and transmits the waiting state information to the information delivery destination of the user ID corresponding to the temporary ID.

  • Patent number: 9779568
    Abstract: In a coin-operated locker, a short-range wireless communication unit receives UIM information, which is information for connection to a mobile communication network, from a wearable device by short-range wireless communication. A server communication unit communicates with an authentication server that holds authentication-relevant information by mobile communication using the UIM information. The server communication unit receives authentication information from the authentication server. An authentication unit performs authentication using the authentication information received from the authentication server and a locking control unit performs locking control on the basis of the authentication result from the authentication unit.

  • Patent number: 8423859
    Abstract: It is possible to provide a terminal device, a terminal device control method, and a recording medium which enables an error correction without modifying hardware. The terminal device receives a data stream formed in the NAL Unit by a hard decoder based on the H.264 standard. The terminal device includes error correction means which analyzes data encoded in the data stream by software and performs an error correction before inputting the data to the hard decoder.
