  • Patent number: 7814120
    Abstract: A buddy list manager stores a buddy list sent from a receiver terminal and manages the buddy list. A controller accepts an updating request and identifying information of a third party terminal from the third party terminal. When the controller accepts the updating request and the identifying information from the third party terminal, the controller determines whether the third party has an updating authority for updating the buddy list or not, using the identifying information. If the controller judges that the third party has an updating authority for updating the buddy list, then the controller permits the third party terminal to update the buddy list.

  • Patent number: 7763365
    Abstract: A polymer light emitting material, wherein the material has a light emitting mechanism based on transition from an excited triplet state to a ground state or transition through an excited triplet state to a ground state of an electron energy level, and the material comprises a nonionic light emitting part which constitutes a part of the polymer or is bound to the polymer. The polymer light emitting material exhibits high light emission efficiency above 5%, which is the limit of external quantum efficiency of fluorescence and can be designed so as to have a large area and hence are suitable for mass production of organic light emitting devices.

  • Patent number: 7752273
    Abstract: When the status of a client X is changed to a status i, a group management unit generates a group agent Xi, corresponding to the status i and registers the generated group agent in the server S, and the presence issuing unit issues the status i and the identifier of the group agent Xi. Initially, a member management unit of the group agent xi manages the client X only. When other clients, such as clients B and C, that are observing the status of the client X send an instant message (IM) to the group agent Xi identified by the issued identifier, an IM delivery unit of the group agent Xi adds the clients B and C, which are IM senders, to the members managed by the member management unit and sends the IM to all members.

  • Publication number: 20100146632
    Abstract: When a viewer views content, it is reproduced by a reproduction procedure depending on a dynamic condition set in the content. Here, a content object data input unit obtains an externally-input content object. The content object is stored in a content object data retention unit, if necessary. The content object includes a reproduction rule and a content data. A reproduction rule evaluation and execution unit obtains the reproduction rule in the content object and performs processing in accordance with the reproduction rule. The reproduction unit reproduces a reproducible data specified by the reproduction rule evaluation and execution unit. An identifier management unit retains an identifier of a content object reproduction device and provides the identifier upon request. It is thus possible to reproduce in accordance with the reproduction rule set in the content object data and to control the reproduction procedure depending on the dynamic condition.
