Patent number: 7239278Abstract: A detection system includes a sensitiveness level setup control section and a receiver control section. The sensitiveness level setup control section looks into a sensitiveness level setup file and finds the sequence of levels of sensitiveness to the received signals corresponding to the setup ID. The receiver control section converts, for each component, a sequence of levels of sensitiveness to received signals received from the sensitiveness level switching section into signals for designating levels of sensitiveness to received signals corresponding to the respective receivers, and transmits the signals for designating levels of sensitiveness to received signals through the communication network.Type: GrantFiled: July 7, 2004Date of Patent: July 3, 2007Assignee: Kabushiki Kaisha ToshibaInventors: Takashi Koiso, Kanako Hattori, Naoki Imasaki, Shigeru Kambayashi

Patent number: 6963277Abstract: A behavior of a group of persons is monitored. Each person is given a radio frequency identification tag. Tag identification information that is unique to the radio frequency identification tag, and reader identification information that is unique to a tag reader, which detects the radio frequency identification tag, are acquired. A position of each of the persons in the group is detected based on the tag identification information and the reader identification information. A position of majority of the persons in the group is regarded as the position of the group. If the position of a person is different from the position of the group, then that person is determined as having parted from the group.Type: GrantFiled: March 25, 2003Date of Patent: November 8, 2005Assignee: Kabushiki Kaisha ToshibaInventors: Naoki Imasaki, Hideyuki Aisu, Toshiaki Tanaka, Takeichiro Nishikawa

Patent number: 5983210Abstract: Each of a plurality of units 2 has the learning section 9 which updates the parameters PRM and performs learning. The learning means 9 modifies the parameters PRM based on the error signal OS' propagated from one unit to another. To build a system consisting of such units 2, the user uses the GUI or some other method to select the units 2 as well as the signal paths for connecting the units via the user interface, displays the system configuration status, and adjusts the functions of units 2. Therefore, an easy-to-build data processing system and a system-build system and method used to build such a system can be provided.Type: GrantFiled: December 23, 1996Date of Patent: November 9, 1999Assignee: Kabushiki Kaisha ToshibaInventors: Naoki Imasaki, Hideyuki Aisu, Satoshi Sekine, Makoto Kano, Kyoko Makino

Patent number: 5347447Abstract: The basic state feedback gain is derived and selected by the on-line identification based on the on-line input/output data of a controlled object, and at the same time, the sensitivity of the state feedback gain is directly and sequentially calculated based on the on-line input/output data of the controlled object. The state feedback gain is finely adjusted when the state feedback gain is not optimum. Further, the sensitivity of the state feedback gain of the controlled object is derived by the feedback gain sensitivity calculating unit according to the on-line input/output data of the controlled object. When the sensitivity is determined to be zero based on the criterion by the controller, the state feedback gain is determined to be optimum. When the sensitivity is determined to be near zero, the state feedback gain is finely adjusted by use of the sensitivity.Type: GrantFiled: October 27, 1992Date of Patent: September 13, 1994Assignee: Kabushiki Kaisha ToshibaInventors: Junichi Kiji, Naoki Imasaki, Tsunekazu Endo
