Cheng-Hao Yu 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: 11270950
    Abstract: An apparatus and a method for forming alignment marks are disclosed. The method for forming alignment marks is a photolithography-free process and includes the following operations. A laser beam is provided. The laser beam is divided into a plurality of laser beams separated from each other. The plurality of laser beams is shaped into a plurality of patterned beams, so that the plurality of patterned beams is shaped with patterns corresponding to alignment marks. The plurality of patterned beams is projected onto a semiconductor wafer.
    Type: Grant

  • Patent number: 8355010
    Abstract: A load cell touch control device includes a touch panel, a plurality of load cells and a control unit. The touch panel receives a stress applied thereon. The load cells are implemented in the touch panel to detect respective components of the stress received by the touch panel. The control unit is connected to the load cells in order to receive magnitudes of the respective components to thereby calculate a magnitude, position and motion trace of the stress on the touch panel based on the respective components detected by the load cells in the touch panel.

  • Publication number: 20100061790
    Abstract: A label roll holder returning mechanism is provided for a barcode printer and includes at least one restoration roller, a coiled resilient element, at least two movable rails, and at least two label roll holding elements. The restoration roller is rotatably mounted to a bottom of the barcode printer and has a top portion forming a positive-movement engagement section. The coiled resilient element is received inside the restoration roller to provide a restoration force to the rotation of the restoration roller. The movable rails are set to the bottom of the barcode printer in a substantially parallel manner. Each movable rail has a surface forming at least one counterpart positive-movement engagement section engaging the positive-movement engagement section of the restoration roller.
