  • Patent number: 11972537
    Abstract: A method for flattening a three-dimensional shoe upper template is provided. The method includes providing a three-dimensional last model, obtaining a three-dimensional grid model, obtaining a three-dimensional thickened grid model, obtaining a two-dimensional initial-value grid model, and obtaining a two-dimensional grid model with the smallest energy value. A system and a non-transitory computer-readable medium for performing the method are also provided. The method makes it possible to precisely flatten a three-dimensional last model with a non-developable surface and thereby convert the three-dimensional last model into a two-dimensional grid model.

  • Patent number: 7471893
    Abstract: A digital camera has a printed circuit board which comprises a main area and a flexible area. An optical sensor chip (e.g. a CCD) is fixed onto the flexible area. The flexible area has flexible character relative to the main area. Therefore, even if the printed circuit board is stressed, such stress will be almost or completely eliminated in the flexible area, so that the optical sensor chip and an optical lens can be coupled together in a precise manner.
