    摘要: Disclosed herein is a shock absorber for damping vibration transmitted to a vehicle according to a road state. The shock absorber includes a cylinder and a piston valve disposed within the cylinder and connected to a piston rod to divide the cylinder into a first chamber and a second chamber. The piston rod includes a hollow chamber formed within the piston rod, first and second orifices formed in upper and lower ends of the hollow chamber and connected to the first and second chambers, respectively, a floating piston disposed within the hollow chamber to move up and down and to divide the hollow chamber into upper and lower chambers, and a moving mechanism formed in the hollow chamber to move an operating fluid to upper and lower portions of the floating piston. The shock absorber can change a damping force according to a displacement of the piston rod, thereby improving driving comfort and stability of the vehicle.

    摘要: An apparatus and method for detecting a moving object in a sequence of color frame images is provided. The apparatus comprises a color normalizer for normalizing color components of the color frame image to produce a normalized frame image; a color transformer coupled to the color normalizer for color transforming the normalized frame image to a color transformed frame image; the color transformed frame image having intensity levels such that colors corresponding to said moving object are emphasized; a frame delay coupled to the color transformer for delaying the color transformed frame image by one frame; and a motion detector coupled to the color transformer and the frame delay for detecting the motion of the moving object and further intensifying the intensity levels of the color transformed frame image based on the detected motion.

    摘要: A method of manufacturing thermosets such as epoxy resins includes adding expandable hollow microspheres, which expand with temperature as shown in the accompanying graph, to the base thermoset components in the liquid phase and applying heat treatment to the mixture so formed causing the micropsheres to expand during or after curing of the thermoset. This results in a toughening mechanism caused by compressive residual stress around the microspheres which significantly increases the specific fracture energy of the epoxy resin.
