Patent number: 10436671Abstract: A shock-resistance testing apparatus includes a support base, a first rotating component and a controller provided on the support base. A second rotating component is coupled to one side of the first rotating component. A testing board is placed on the first rotating component. A falling board is placed on the testing board. The controller controls the first rotating component to drive the second rotating component rotating from one side of the testing board to another side of the testing board. The controller controls the second rotating component to lift the testing board. The controller controls the second rotating component to move away from the testing board so that the testing board falls.Type: GrantFiled: March 1, 2017Date of Patent: October 8, 2019Assignees: Fu Tai Hua Industry (Shenzhen) Co., Ltd., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Kang-Xian Yang, Ke-Rui Zeng, Kun-Jia Hsieh, I-Cheng Huang, Wen-Hsien Huang

Patent number: 10264952Abstract: A method for positioning an endoscope involves installing an auxiliary positioning device on a robot arm, coinciding a terminal of a docking member of the auxiliary positioning device with a spherical remote center of motion defined by the robot arm, inserting and fixing the endoscope inside the auxiliary positioning device, removing the docking member of the auxiliary positioning device so that a terminal of the endoscope coincides with the spherical remote center of motion of the robot arm, and then inserting the endoscope into a body cavity catheter for finalizing positioning. Thereby, the method helps to save time used for preoperative preparation and provides more precise positioning, without using any additional positioning tools to approach the body cavity, thereby reducing the risk of infection.Type: GrantFiled: March 24, 2015Date of Patent: April 23, 2019Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Hung-Ju Yang, Kun-Jia Hsu, Ren-Jeng Wang
