  • Publication number: 20170144599
    Abstract: This application relates to an apparatus and a method for creating an image of the area around a vehicle. The apparatus for creating an image of the area around a vehicle creates an aerial-view image by converting an image of an area around a vehicle; creates a movement-area aerial-view image that is an aerial view of a movement area of the vehicle; creates a combined aerial-view image by combining a subsequent aerial-view image, which is a current image created after the previous aerial-view image is created, with the movement-area aerial-view image that is a past image; and creates a corrected combined aerial-view image by correcting an image to differentiate the subsequent aerial-view image that is the current image and the movement-area aerial-view image.

  • Publication number: 20170148136
    Abstract: This application relates to an apparatus and a method for creating an image of the area around a vehicle. The apparatus for creating an image of an area around a vehicle according to this application includes: a camera unit that creates an image of a peripheral area; an aerial-view image creation unit that creates an aerial-view image by converting a view point of the taken image; a movement information extraction unit that extracts information about movement of the vehicle; a movement-area aerial-view image creation unit that creates a movement-area aerial-view image, which is an aerial view of the area to which the vehicle has moved; and a combined aerial-view image creation unit that combines an aerial-view image subsequent to the previous aerial-view image with the movement-area aerial-view image.

  • Patent number: 5692645
    Abstract: In a wall or other vertical surface mounted dispensing apparatus which receives a tube of viscous material has a base which supports a pair of substantially vertical gear tracks for receiving a cylindrical roller which has a plurality of gear teeth about the periphery at each end of the roller for engagement with said gear tracks. The roller is provided with a handle mounted on and axle which is rotatably attached to the roller through end caps which maintain the axle along the central axis of the roller but permit rotation relative to the roller. A cover holds the roller in place by exerting pressure on the cylindrical surface adjacent to the peripheral gears. The axle engages a pair of weights a point offset free the central axis of the weight which cause rotation of the crank arm in the upwards direction when released. A recoil arm mounted on a rectangular section of the axle is displaceable along its longitudinal axis.
