  • Patent number: 6188388
    Abstract: A pointer remotely points a display screen of a large screen display device. The display screen is picked up by a monitor camera. An image processing unit extracts a feature of the pointer used for pointing based on the resulting image signal to identify the position of the pointing point and the pointer based on the feature. A computer generates information on an object to be displayed at a position pointed by the pointer. The generated information is displayed on a display device (CRT display device or large screen display device) assigned to the pointer. Even when a plurality of pointers are used, the information on the object to be displayed pointed by the pointer is properly displayed.

  • Patent number: 5777896
    Abstract: In an apparatus for operating and monitoring a plant, a manipulating device provides the plant with manipulation signals for operating the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device, a first display data producing device produces first display data needed for the operation of the plant changing every moment. On the basis of data supplied from the first display data producing device, a first display device displays information relating to the operation of the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device, a second display data producing device produces data needed for monitoring the plant. On the basis of data supplied from the second display data producing device, a second display device displays information relating to the monitoring of the plant on a larger display screen than that of the first display device.

  • Patent number: 5701394
    Abstract: Disclosed is an information processing system having a neural processing unit, an expert system for executing an inference using a rule, and an information selection unit. The neural processing unit and the expert system being arranged in parallel to each other. The information selection unit selects and outputs necessary information from the information outputted from the neural processing unit and the expert system. Since necessary information is selected and outputted from the information obtained from the neural processing unit and the expert system as a result of processing executed by the neural processing unit and the expert system in the parallelly different points of view, the certainty of the information to be selected is improved.

  • Patent number: 5677993
    Abstract: Each character string information obtained based on each information inputted by the CRT touch input device and the speech input device respectively is integrated by the input control unit and the memory. The input information analyzing unit analyses the integrated character string information. The output information generating unit generates presentation information corresponding to the demand information obtained by the analysis and outputs this presentation information to the display device. Since the input information from each input device is converted into character string information and it is integrated together and is then analyzed, input information is not restricted by each input device and each input device can be used in a free combination when information is inputted.

  • Patent number: 5581242
    Abstract: An alarm system in a plant for outputting a plurality of alarms with respect to devices constituting the plant and monitor information with respect to the devices. In the system, there is provided a unit for storing a table for correspondingly relating a plurality of alarm items to suppression reason items indicating that the display of the alarms can be suppressed. A generated alarm item and a generated event are specified by receiving the plurality of alarms and monitor information. A decision is made by reference to the table as to whether the generated alarm suppression reason item exists in the monitor information, the kind of generated alarm, and the generated event for each generated alarm item. An instruction is given to a display unit to suppress the display of alarms in which a decision is made that the suppression reason item exists.
