Patent number: 7864671Abstract: A connection control apparatus includes a monitoring unit, a determining unit, a transferring unit, and a notifying unit. The monitoring unit monitors a status of a communication terminal. The determining unit determines, on a basis of a monitoring result, whether or not the communication terminal is able to respond to a connection request therefor. The transferring unit transfers the connection request to the communication terminal when the transferring unit has received a connection request for the communication terminal and the determining unit determines that the communication terminal is able to respond to the connection request. The notifying unit calls attention around the connection control apparatus when the determining unit determines that the communication terminal is unable to respond to the connection request after the transferring unit has received the connection request.Type: GrantFiled: September 23, 2005Date of Patent: January 4, 2011Assignee: Kabushiki Kaisha ToshibaInventors: Kensaku Yamaguchi, Shinya Murai, Junko Ami

Patent number: 7529237Abstract: Communication packets having a same channel identifier are exchanged between a pair of Bluetooth devices within a Bluetooth network. The packets are passed to a lower level layer through a connection handle in which their requested quality of service is indicated. In the lower level layer, the communication packets are distributed to buffers, each of which corresponds to each type of quality of service set in the connection handle. Alternatively, a service identifier corresponding to the quality of service is given to the communication packets in the lower level layer, and the packets are distributed to a suitable buffer based on the service identifier.Type: GrantFiled: February 13, 2002Date of Patent: May 5, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Junko Ami, Yoshiaki Takabatake

Publication number: 20070233663Abstract: An acquiring unit acquires a first search criterion from outside. A first searching unit extracts a first search result that satisfies the first search criterion from a storing unit that stores information to be searched. A first output unit outputs the first search result to a first output device. A changing unit changes the first search criterion to a second search criterion based on a predetermined condition. A second searching unit extracts a second search result that satisfies the second search criterion from the storing unit. A second output unit outputs the second search result to a second output device that is different from the first output device.Type: ApplicationFiled: March 1, 2007Publication date: October 4, 2007Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Junko Ami, Yasuyuki Masai, Takehide Yano, Hisayoshi Nagae, Kazuhiko Abe, Tetsuya Sakai, Hideki Tsutsui, Kazutaka Ohigashi

Patent number: 6885643Abstract: A wireless network system capable of controlling highly efficient transfer of AV data by an upper application, using information indicating a wireless link condition that varies dynamically is disclosed. In this wireless network system, a wireless terminal and a wire gateway apparatus each store collected wireless link condition information in a descriptor. An upper application on the wireless terminal reads the descriptor at said terminal device and obtains wireless LAN link condition information. The wireless gateway apparatus makes notification to a wireless terminal of a VTR, for example, that actually exists in a 1394 terminal as if it existed as a sub-unit in the local terminal device. The wireless terminal accesses the collected wireless link condition information and selects a AV/C command to be sent to the VTR sub-unit of the wireless gateway apparatus. The wireless terminal transfers the play command for playback to the wireless gateway apparatus.Type: GrantFiled: September 28, 2000Date of Patent: April 26, 2005Assignee: Kabushiki Kaisha ToshibaInventors: Keiichi Teramoto, Yoshiaki Takabatake, Junko Ami, Kensaku Fujimoto
