  • Publication number: 20150268346
    Abstract: According to one embodiment, an optical axis directing apparatus includes a base, a lens, a light source, a beam splitter, an image sensor, an image processor, and a galvano scanner. The lens is supported on the base and has a wide viewing angle. The light source generates first light. The beam splitter allows transmission of at least one of the first light traveling to the lens and second light traveling from the lens. The image sensor acquires the second light from the beam splitter and acquires an image of the second light. The image processor receives the image and calculates a position of a feature point included in the image. The galvano scanner receives the first light and defines an optical path along which the first light travels to the position through the lens.

  • Patent number: 9106366
    Abstract: Provided are techniques for distributing data in a trackable manner while suppressing an increase in the size of data to be distributed as much as possible and minimizing interruption of usage of the data. A method for distributing data to multiple clients from a server includes the steps of: generating a common noise by using noises unique to the multiple clients, respectively; embedding the common noise in the data to be distributed to make the data unusable; and distributing the data containing the embedded common noise, so that the data containing the embedded common noise is made usable by each of the multiple clients using a unique noise generated in the client.

  • Publication number: 20150113061
    Abstract: A user causes a portable device (information processing device) to approach one PC (communication apparatus), and the PC transfers to the portable device by means of NFC unique connection information, such as a password, required for communication connection. Also, the user causes the portable device which has obtained the connection information to approach another PC. The portable device transfers connection information unique to the one PC to another PC by means of NFC. Another PC uses the obtained connection information to execute communication connection with the one PC. Thus, connection information required for communication connection is transferred among a plurality of PCs so as to easily execute communication connection among the plurality of PCs.
