  • Patent number: 11042746
    Abstract: In an approach for presenting information on an object to be observed, a processor obtains information from a sensor about an object. A processor predicts a time period in which the object is expected to be at a location and in a state, based on historical data, obtained from the sensor, associated with the object. A processor determines whether the object is at the location and in the state within the time period. A processor presents information to a user, wherein the information is about the object.

  • Patent number: 10983743
    Abstract: A programmable display includes a display data generator that generates display data for pages corresponding to their page identifier, a display portion that displays a page corresponding to the page identifier on its display screen based on the display data that is generated by the display data generator, and a touch detector that detects touch operations on the display screen of the display portion. The display portion generates display data for displaying the device wave of the device that is specified by the subject device settings based on the chronological data, which is stored in the PLC, when the touch detector detects a predetermined second touch operation on the display screen. The display portion displays a second page or a device wave on the display screen based on the display data that is generated by the display data generator.

  • Patent number: 10948039
    Abstract: A braking system of an industrial vehicle includes an accumulator accumulating hydraulic oil, a hydraulic oil cooler cooling the hydraulic oil, an electromagnetic switch valve switching between an oil channel for the accumulator that allows supplying the hydraulic oil from a hydraulic pump to the accumulator and an oil channel for the hydraulic cooler that allows supplying the hydraulic oil from the hydraulic pump to the hydraulic oil cooler, and a controller controlling the electromagnetic switch valve to switch from the oil channel for the hydraulic cooler to the oil channel for the accumulator with timing of an increase after a drop in an engine speed when a cargo-handling operation is detected while an oil is at a setting pressure value or less and while the engine speed is at a setting engine speed or less.

  • Patent number: 10936568
    Abstract: Displaying pieces of data includes displaying a tree structure on a display device, identifying, in response to a first node being selected from among nodes constituting the displayed tree structure, all nodes connected to the first node in a high-order direction and a low-order direction as a first node group, and identifying, in response to a second node being selected, the second node not being included in the first node group, all nodes connected to the second node in the high-order direction and the low-order direction as a second node group. The second node moves toward the first node according to an operation. A node not to be displayed is determined according to a rule and movement of the second node group. A display device is instructed to display the first node group and the second node group close to each other omitting display of the determined node.
