  • Publication number: 20230370726
    Abstract: A visible light communication method transmits a signal by visible light communication. The visible light communication method includes modulating the signal into a predetermined blinking pattern, and transmitting the signal by causing visible light to blink according to the predetermined blinking pattern, from a projector disposed in an indoor space surrounded by a wall toward the wall. The visible light communication method also includes projecting video from the projector toward the wall, wherein the visible light is reflected by the wall to prevent the signal from being received in an outside of the indoor space, and the signal is used to transmit data related to the video projected to a terminal in the indoor space.

  • Patent number: 11781511
    Abstract: A fuel supply device includes a flange unit and a pump unit. The flange unit includes a flange main body for closing an opening formed in an upper wall of a fuel tank. The pump unit includes a joint member that is connected to the flange main body so that both components may be movable relative to each other in the vertical direction. The interval in the vertical direction between the flange main body and the joint member is restricted from going below a minimum vertical interval. The minimum interval occurs when a stand-off portion provided as part of the flange main body and a connecting plate portion provided as part of the joint member come into mutual contact with each other and abut each other in the vertical direction.

  • Patent number: 11767055
    Abstract: Provided are a lane separation line detection correcting device/method and an automatic driving system for stabilizing the behavior of a vehicle by correcting overestimated curvature information resulting from an erroneous detection of a curvature of a lane separation line. A travel speed detecting circuit detects, for example, a target travel speed as vehicle sensor information. A maximum curvature estimating circuit estimates, based on the target travel speed, a maximum curvature of a road along which an own vehicle is traveling. A curvature correcting circuit corrects a curvature of a lane separation line input thereto based on the maximum curvature. A control unit controls steering of the own vehicle based on the lane separation line having a corrected curvature. As a result, vehicle steering can be automatically controlled so as to prevent the own vehicle while traveling from departing from a driving lane.
