  • Patent number: 11964881
    Abstract: A method for making iridium oxide nanoparticles includes dissolving an iridium salt to obtain a salt-containing solution, mixing a complexing agent with the salt-containing solution to obtain a blend solution, and adding an oxidating agent to the blend solution to obtain a product mixture. A molar ratio of a complexing compound of the complexing agent to the iridium salt is controlled in a predetermined range so as to permit the product mixture to include iridium oxide nanoparticles.

  • Patent number: 11943939
    Abstract: An integrated circuit (IC) device includes a substrate and a circuit region over the substrate. The circuit region includes at least one active region extending along a first direction, at least one gate region extending across the at least one active region and along a second direction transverse to the first direction, and at least one first input/output (IO) pattern configured to electrically couple the circuit region to external circuitry outside the circuit region. The at least one first IO pattern extends along a third direction oblique to both the first direction and the second direction.

  • Patent number: 10685474
    Abstract: The present invention provides a method for repairing incomplete 3D depth image using 2D image information. The method includes the following steps: obtaining 2D image information and 3D depth image information; dividing 2D image information into 2D reconstruction blocks and 2D reconstruction boundaries, and corresponding to 3D reconstruction of blocks and 3D reconstruction boundaries; analyzing each 3D reconstruction block, partitioning into residual-surface blocks and repaired blocks; and proceeding at least one 3D image reconstruction, which extends with the initial depth value of the 3D depth image of each of the residual-surface block and covers all the corresponding repaired block to form a repair block and to achieve the purpose of repairing incomplete 3D depth images using 2D image information.

  • Patent number: 7850315
    Abstract: A light integration rod having a light input end and a light output end opposite to each other is provided. The light integration rod includes a first reflective plate, a second reflective plate, a third reflective plate and a fourth reflective plate. The second reflective plate is opposite to the first reflective plate. The third reflective plate and the fourth reflective plate connect the first reflective plate and the second reflective plate, and are disposed opposite to each other. A long side of the first reflective plate is not equal to a long side of the second reflective plate. A short side at the light output end of at least one of the first reflective plate and the second reflective plate is separate from a short side of the third reflective plate and a short side of the fourth reflective plate at the light output end.
