  • Patent number: 11203990
    Abstract: A vehicle equipped with an automatic stop/restart system for an internal combustion engine includes a hydraulic continuously variable transmission and a parking mechanism. The continuously variable transmission changes power of the internal combustion engine using hydraulic pressure boosted by rotational driving force of the internal combustion engine. The parking mechanism holds the vehicle stationary by locking, with a locking member, the rotation of a power transmitting member between the internal combustion engine and driving wheels when a shift position is in a parking range. In an automatic stop state of the internal combustion engine, when the shift position is in the parking range and brakes are turned off, an electronic control unit executes restart if an inclination angle of the vehicle is greater than or equal to a predetermined value, and maintains the automatic stop state if the inclination angle is smaller than the predetermined value.

  • Patent number: 9926156
    Abstract: A sheet size specification system for specifying size of a sheet on a sheet stacking tray of an image forming device, by using an image capture unit of a portable terminal. The system includes an analyzer and a size specifier. The analyzer analyzes image data captured by the image capture unit, the image data indicating the sheet stacking tray and the sheet thereon. The size specifier acquires, from the analyzed image data, first position data indicating positions of predefined feature points of the sheet stacking tray and second position data indicating positions of an outline of the sheet, and specifies size of the sheet on the sheet stacking tray based on the first position data and the second position data.
