  • Patent number: 11577737
    Abstract: A heat management device for a vehicle equipped with heat related systems includes an acquisition unit and a flow rate control unit. The acquisition unit is configured to acquire a temperature related value from electronic control devices corresponding to the heat related systems. The temperature related value includes a temperature adjustment related value and/or an upper limit value. The flow rate control unit is configured to control switching devices that switch flow rate of fluid flowing through the heat related systems from a common path in which the fluid can circulate between the heat related systems. The flow rate control unit controls flow rate of the fluid flowing from the common path to the heat related systems by controlling the switching devices in response to the temperature related value acquired by the acquisition unit for a predetermined scene of the vehicle.

  • Patent number: 8807810
    Abstract: Three-dimensional information is presented directly on the surface of a target three-dimensional object without using a display device such as a display monitor and an HUD. Spatially coded light patterns are projected from two projectors on a target object surface. The light projected from the two projectors are added up on the object surface to produce unified color and luminance. On the object surface, light is simply added up, so that a pattern whose color and brightness correspond to distance and height appears. Hence, a distance to an object or a three-dimensional shape of an object can be highlighted by the color and brightness presented on the object for perception by human beings.

  • Patent number: 5401089
    Abstract: A lifter particularly usable for an LC display unit includes a slide board bearing the display unit overhead and driven for vertical movement by a lift drive motor associated with a swing arm kept in rolling contact with the slide board, a gear assembly mounted to the slide board for converting rotation of a tilt drive motor into corresponding tilting of the display unit, and various sensors for controlling rotation of the motors on detection of the positions of the display unit. Vertical movement of the display unit requires a quarter rotation of the swing arm which is very small in ambit and, as a consequence, a compact and light design of the entire lifter construction. The rolling contact of the swing arm with the slide board assures reliable fail-safe function when smooth vertical movement of the slide board is hindered by accidental introduction of a foreign matter in its path of travel.
