  • Patent number: 10956010
    Abstract: A tool allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. Based on a laser input file with a pattern, a laser will burn the pattern onto apparel. With the tool, the user will be able to create, make changes, and view images of a design, in real time, before burning by a laser. Input to the tool includes fabric template images, laser input files, and damage input. The tool allows adding of tinting and adjusting of intensity and bright point. The user can also move, rotate, scale, and warp the image input.

  • Publication number: 20100288729
    Abstract: Methods for manufacturing a microstructure, wherein use is made of a powder blasting and/or etching and a single mask layer with openings and structures of varying dimensions, wherein the mask layer at least at one given point in time has been wholly worn away within at least one region by mask erosion while the microstructure is not yet wholly realized. Use can be made of a combination of ‘vertical’ erosion, i.e. parallel to the thickness direction and ‘horizontal’ erosion, i.e. perpendicularly of the thickness direction, of the mask layer. The horizontal mask erosion occurs at the edges of the mask structure.

  • Publication number: 20090258577
    Abstract: The present invention provides a method for trimming molds of automotive metal sheets, which comprise a top mold and a bottom mold. The top mold has a concave mold surface, and the bottom mold has a corresponding convex mold surface. The method comprises: 1. Use the top mold as the base mold, and smear dye on the top mold; 2. Close the bottom mold to the top mold; and 3. Polish the mold surface of the bottom mold. Thereby, the processing method according to the prior art is broken through, and an ergonomic trimming operation is hence provided. Accordingly, the trimming process is simplified, and the labor hours are reduced. Beside, the accuracy of trimmed molds is improved and the subsequent mold-clamping process can be omitted. Thereby, the exterior quality of the metal sheets can be enhanced while reducing substantial labor hours, and economic benefits for manufacturing molds of metal sheets for an automotive body can be achieved.

    Abstract: The invention is directed to large LCD image masks having a final flatness of less than 40 nm and a method of making such LCD image masks by utilizing subaperture deterministic grinding/lapping/polishing. In one preferred embodiment the final flatness is <20 ?m. In another the final flatness is <10 nm. The LCD image masks have a length and width that are each, independently of the other, greater than 400 mm and a thickness that is less than 20 mm. In at least one preferred embodiment the ICD image masks have a length and width that are each, independently, greater than 100 mm and the thickness is <15 mm. The glass LCD image masks can be of any glass materials suitable for LCD image masks. The method of the invention can be used with all such glasses. Exemplary LCD image mask glasses include fused silica, high purity fused silica and silica-titania containing 5-10 wt. % titania.
