  • Patent number: 10436173
    Abstract: Provided are a rotary device for fluid power generation and a fluid power generation device that are capable of converting the kinetic energy of a fluid to an electric energy. By utilizing a longitudinal vortex as a driving force, a rotary body such as a cylinder as a high-strength and tough wing-shaped member can be rotated, and power can be efficiently generated in a wide range of flow rate without letting the longitudinal vortex disappear even if the flow rate changes in a wide range. This rotary device for power generation includes a rotary body 3; and a wake body 8 that is a distance away from the rotary body 3 toward the downstream side of a flow direction 10 of the fluid, and has at least one crossover section at which the wake body 8 intersects with the rotary body 3.

  • Patent number: 10343603
    Abstract: An image processing device according to an embodiment includes an image acquisition unit, an information acquisition unit, a generation unit, a composition unit, a determination unit, and a display control unit. The image acquisition unit acquires a captured image where an image of an environment of a vehicle is captured by an image-capturing device. The information acquisition unit acquires positional information regarding a detected position of an obstacle that exists in an environment of the vehicle. The generation unit generates a virtual viewpoint image where an environment of the vehicle is viewed from a virtual viewpoint, based on the captured image. The composition unit composites a notification image that provides notification of existence of the obstacle at the detected position with the virtual viewpoint image. The display control unit controls a display format of the notification image that is composited with the virtual viewpoint image, based on the positional information.
