Patent number: 11951637Abstract: A calibration apparatus includes a processor, an alignment device, and an arm. The alignment device captures images in a three-dimensional space, and a tool is arranged on a flange of the arm. The processor records a first matrix of transformation between an end-effector coordinate-system and a robot coordinate-system, and performs a tool calibration procedure according to the images captured by the alignment device for obtaining a second matrix of transformation between a tool coordinate-system and the end-effector coordinate-system. The processor calculates relative position of a tool center point of the tool in the robot coordinate-system based on the first and second matrixes, and controls the TCP to move in the three-dimensional space for performing a positioning procedure so as to regard points in an alignment device coordinate-system as points of the TCP, and calculates the relative positions of points in the alignment device coordinate-system and in the robot coordinate-system.Type: GrantFiled: June 4, 2021Date of Patent: April 9, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Cheng-Hao Huang, Shi-Yu Wang, Po-Chiao Huang, Han-Ching Lin, Meng-Zong Li

Publication number: 20220120958Abstract: A method to form a light wave-guide optical element is disclosed. First, a flat organic optical layer is formed on an optically transparent substrate before using a template to transfer a pattern onto the flat organic optical layer to obtain a patterned organic optical layer. Then the patterned organic optical layer is cured in the presence of the template to obtain an organic optical material disposed on the optically transparent substrate before removing the template from the organic optical material. Later an anti-reflection stack is formed to conformally cover the organic optical material before applying an organic optical cover layer on the anti-reflection stack to cover the anti-reflection stack.Type: ApplicationFiled: January 3, 2022Publication date: April 21, 2022Applicant: HIMAX TECHNOLOGIES LIMITEDInventors: Yin-Dong Lu, Han-Yi Kuo, Han-Ching Lin
