  • Patent number: 10991173
    Abstract: The present invention is one that enables an actual vehicle run on a chassis dynamometer to be reproduced in a vehicle drive train test, and includes: a loading device to be connected to a rotating shaft of a vehicle drive train; and a load controller that controls the loading device to change a load. In addition, the load controller includes a relationship data storage part adapted to store speed-load relationship data indicating the relationship between rotation speed of the loading device and a load corresponding to the rotation speed, and changes the timing of the load to be given by the loading device correspondingly to the rotation speed of the loading device with respect to timing determined by the speed-load relationship data. Alternatively, the load controller changes the load correspondingly to the rotation speed of a roller mounted with a tire in the chassis dynamometer.

  • Patent number: 10664063
    Abstract: A portable computing device includes a touch screen with a display, and a controller that causes a keyboard image and first and second command graphics to be displayed. The first and second command graphics each contain a direction-specifying area for selecting a direction of movement of a cursor that is movable within the keyboard image and a selection input area. Touch position information concerning whether the direction-specifying area or the selection input area has been touched is generated by the controller. When the direction-specifying area of the first or second command graphic is touched, the corresponding cursor is moved in one or more discrete key image units in the direction of movement indicated by a portion of direction-specifying area that was touched; when the selection input area is touched, the character of the character key image that the cursor is currently superimposed upon is displayed on the character display field.

  • Patent number: 10585288
    Abstract: When an imaging apparatus (30) captures an image of a finger performing an operation on a visual confirmation screen (S2), an operation determining unit (73) of a computer display device (1) mounted on eyeglasses (10) determines the contents of the operation performed by the finger based on image data obtained by the imaging apparatus (30). A positional data generating unit (74) generates positional data of the finger based on the image data. Based on data concerning the determined contents of the operation performed by the finger, the generated positional data of the finger, and reference data concerning the visual confirmation screen stored in a storage unit (90), an input control unit (76) determines the contents of an inputted instruction corresponding to the operation performed by the finger, and controls an original screen to be displayed on an display apparatus (20) in accordance with the determined contents of the inputted instruction.

  • Patent number: 10581682
    Abstract: It is possible to update firmware of domain masters during travelling. An in-vehicle communication system includes a plurality of domain masters, and a redundant domain master configured to be able to perform alternative operations of the plurality of domain masters. The domain masters transmits operation information to the redundant domain master prior to update of firmware. The redundant domain master executes the alternative operation of the domain master using the received operation information. The domain master receives, after the update of the firmware, operation information generated in the alternative operation from the redundant domain master and operates in the updated firmware.
