  • Patent number: 7239278
    Abstract: 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.

  • Patent number: 7123126
    Abstract: A monitoring method includes acquiring tag identification information unique to a radio frequency identification tag carried by a person, and reader identification information about a tag reader that detects the radio frequency identification tag. Next, attribute information about the person is acquired based on the tag identification information, and area information about a detection area of the tag reader is acquired based on the reader identification information. Finally, it is determined whether the person carrying the radio frequency identification tag having the attribute information acquired is allowed to enter into the detection area based on the area information.

  • Patent number: 6963277
    Abstract: 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.

  • Patent number: 5983210
    Abstract: 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.

  • Patent number: 5865274
    Abstract: In a vertically movable elevator group management control apparatus for control of a plurality of transversely shiftable cars among plural shafts, control is done by storing route data with respect to each said car, generating target floor data including a target floor, based on car call data obtained in correspondence with each said car and station call data as obtained correspondingly to each floor, estimating the time taken for said car to reach said target floor, based on at least said route data, said target floor data and said car call data, and assigning a certain car to a certain floor call, based on the estimated arrival time.

  • Patent number: 5347447
    Abstract: 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.
