Abstract: A train detection system is capable of realizing reliable train detection with a train detection apparatus of simple construction using a track circuit. This is attained by a transmitter 11a adding data of a first unique code to a train detecting signal received from wayside controller 100 and transmitting it to a track circuit; a receiver 11b adding data of a second unique code to the train detecting signal added with the first unique code data received from the track circuit and transmitting it to the wayside controller 100; and the wayside controller 100 checking whether or not the data received from the receiver 11b agrees with predetermined data.

Abstract: An objective is to effectively specify a method of synchronizing a video image with computer processing. At step 1200, a frame in which a script is desired to be defined is selected and displayed on the editing region 200 of a display screen. Then, at step 1210, when an item "script" is selected from the editing menu 130, the script editor is opened. At step 1220, a desired process is described in the script editor in terms of a predetermined language. If the description has no error, it is stored (step 1230). When an item "execute" is selected from the main control menu 120, a video image is reproduced, a frame for which a process has been defined is displayed, and at the same time the defined process is executed.

Abstract: A system information input means takes in system information and a system state determining means determines states of the system. A component operation state determination means determines operation states of system stabilizing components. A control plan deciding means decides a control plan of the system in consideration of operation states of the system and the system stabilizing components. In deciding the control plan, a swing mode analyzing means firstly analyzes the swing mode at each place of the system on the basis of waveforms of time domain response simulations. Then, a control allotment setting means determines control allotment for each of the system stabilizing components based on the mode analysis and a control parameter setting means control sets the control parameters of each of the system stabilizing components. If plural control plans are obtained, the optimal one is selected based on eigenvalues of dynamics of the system or by evaluating time domain system responses by simulation method.

Abstract: When presentation is made while displaying presentation information on both of audience-site and presenter-site screens, presenter-site additional information for supporting the progress of presentation is not displayed on the audience-site screen but displayed on the presenter-site screen. When drawing information displayed on the audience-site screen is to be displayed also on the presenter-site screen, the drawing information is displayed after abridged. When presentation is made by using a plurality of screens and when presentation information is to be displayed on any one of the screens, the presentation information is automatically assigned to any one of the screens by assignment deciding functions. As a result, the progress of presentation by the presenter can be smoothened.

Abstract: A plurality of letter output devices (workstations, printers) are connected to a letter data control device by a transmission path. The control device stores letter data for transmission to the letter output devices, and is able to convert that letter data to a desired layout (e.g. from a vector font to a dot font) and then transmits the converted letter data to one or more of the letter output devices. The control device is able to select part of its stored letter data for transmission so that only commonly used letter data need be transmitted during start up of the system. Since a large amount of letter data may be stored in the control device, and only part may be transmitted to the letter output devices, those output devices can have a relatively small memory.

Abstract: A user interface system receives data from input devices and, on input of data, that data is associated with one of a plurality of names, which names are stored in a reference memory. The resulting data signal is processed by suitable a processing device, which determines the operation to be carried out on the data on the basis of selection of one of a plurality of operations stored in a rule base memory, which selection is determined by the name that has been associated with the data. A control output to e.g. a display is then generated by the processing device. One of the operations stored in the rule base memory is that which determines the association of names and data. By configuring the user interface in this way, a more flexible arrangement can be achieved.

Abstract: An improved system and method for controlling the interstand tension in a tandem rolling mill by computing the interstand tension on the basis of detected process data, computing the difference or error between the computed interstand tension and the desired value, and controlling the speed of the rolling stand drive motors so as to cancel the error. A shear is generally disposed upstream of the tandem rolling mill to shear the leading and trailing ends of a workpiece. When the shear is cutting the trailing end of the workpiece, a backward tension is produced between the shear and the first rolling stand of the tandem rolling mill, resulting in abrupt variations of the process data used for the computation of the interstand tension. The system operation will become unstable when such abruptly varying process data are used to compute the interstand tension for the purpose of the motor speed control.
