  • Patent number: 12163288
    Abstract: Treated substrates and methods of forming the same are provided. In an exemplary embodiment, a treated substrate includes lignocellulose and a polymer fixed to the lignocellulose to form the treated substrate. The polymer includes a succinic moiety that can reversibly change between a succinic anhydride and a succinic acid moiety. The treated substrate has a wet tensile index of about 3 newton meters per gram or less.
    Type: Grant

  • Patent number: 11335018
    Abstract: The present application provides a volumetric measuring method and apparatus based on a TOF depth camera, which is achieved by: acquiring depth images; denoising the depth images; selecting a first feature area of the first depth image and a second feature area of the second depth image that have been denoised respectively, traversing each pixel point in the first feature area at multiple traversal speeds, and matching a first depth value of a current pixel point with a second depth value of a target pixel point corresponding to the current pixel point in the second feature area to acquire multiple total similarity values; determining a traversal speed corresponding to a maximum total similarity value as an instantaneous speed at a current moment; calculating a package volume according to the instantaneous speed. The present application effectively solves the problem that an accurate package volume cannot be obtained when a speed of the conveyor belt is not fixed, and high in feasibility.

  • Publication number: 20180045137
    Abstract: An internal combustion engine piston having an internal cooling cavity structure is provided, which includes a piston body, and a ring body fitted with the piston body to form the internal cooling cavity structure. The ring body and the top of the piston body form a first fitting region, and the ring body and a top end of a skirt portion of the piston body form a second fitting region. The first fitting region includes a body fitting portion and a ring body fitting portion arranged at the top of the ring body. Compared with the conventional technology, the ring body welding cylindrical surface in the present application is fitted with the body welding cylinder surface, and the welding seam formed by the welding does not extend into the cooling cavity.
