  • Patent number: 11918703
    Abstract: The present invention relates to an extrudable photocrosslinkable hydrogel comprising a biochemically modified extracellular matrix (ECM) with an electroconductive nanomaterial embedded; a photoinitiator and a solvent, the method for its preparation starting from decellularized extracellular matrices (dECMs) and its applications for preparing electroconductive scaffolds, electroconductive extrudable hydrogels for in situ defect-filling, conductive grafts, in situ or in vitro printed tissues or organs, adhesives for different tissues, or bone adhesives.
    Type: Grant

  • Patent number: 10410406
    Abstract: A method of rendering a three-dimensional point cloud in a two-dimensional display includes inputting the three-dimensional point cloud that includes three-dimensional coordinates of a set of points, creating a depth buffer for the three-dimensional point cloud that includes depth data for the set of points from a viewpoint location. The method further includes determining a foreground depth buffer by, for each respective pixel area of the two-dimensional display, determining a foreground depth by detecting a closest point to the viewpoint location among a subset of the set of points corresponding to the respective pixel area, and assigning a depth of the closest point as the foreground depth for the respective pixel area. The method further includes filtering the depth buffer to obtain a filtered depth buffer by removing points that are not in the foreground, and outputting the filtered depth buffer to the two-dimensional display.
