Ringo CHEUNG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11631634
    Abstract: This disclosure relates to a leadless packaged semiconductor device including a top and a bottom opposing major surfaces and sidewalls extending between the top and bottom surfaces, the leadless packaged semiconductor device further includes a lead frame structure including an array of two or more lead frame sub-structures each having a semiconductor die arranged thereon, and terminals and a track extended across the bottom surface of the semiconductor device. The track provides a region for interconnecting the semiconductor die and terminals, and the track is filled by an insulating material to isolate the lead frame sub-structures.
    Type: Grant

  • Patent number: 11419727
    Abstract: Techniques for fabrication of implant material for the reconstruction of fractured eye orbit may include using an image processing system to analyze a set of two-dimensional images representing a three-dimensional scan of a skull of a patient, automatically detect an orbital fracture in the skull based on the set of two-dimensional images, and identify which/both of the two eye orbits containing any orbital fracture. The techniques may further include, for each of the two-dimensional images in which the orbital fracture is detected, determining a region of interest, and extracting the region of interest. The techniques may further include generating a three-dimensional reconstruction model for the fractured eye orbit, and outputting model data for generating an implant mold for the fractured eye orbit.
