Publication number: 20240167982Abstract: An apparatus and method for testing sensitivity consistency of an acoustic emission sensor are provided. The apparatus uses a cylindrical polymethyl methacrylate (PMMA) rod as a test bench. A clamping seat, a clamping block, and a mounting cylinder are mounted on one end of the test bench in cooperation. Under an action of a pressure spring, an end face of a tested sensor keeps pressure-stable coupling contact with an end face of the test bench. A bracket is mounted on another end face of the test bench, and keeps, together with a fixing seat and the clamping seat, the test bench horizontally placed on a desktop. By adjusting a width and an amplitude of a pulse excitation signal of a signal generator, and according to sensitivity distribution and aggregation between tested sensors, a consistency calculation method is used to screen out tested sensors with first, second, and third sensitivity consistency.Type: ApplicationFiled: September 26, 2023Publication date: May 23, 2024Inventors: Junjiao ZHANG, Yongna SHEN, Gongtian SHEN, Zhiquan WANG, Daqing CHEN

Patent number: 11733475Abstract: A lens barrel includes a front end portion. The front end portion includes an outer surface facing toward an object side and an inner surface facing toward an image side. The inner surface includes an inner side conical surface. The inner side conical surface is connected to the outer surface. The inner-side conical surface includes a plurality of toothed structures, an inner edge near an optical axis and an outer edge away from the optical axis. The outer edge is closer to the image side than the inner edge. The inner edge forms a clear hole. Each of the toothed structures includes a tooth peak and a tooth valley. The tooth peak and the tooth valley are disposed at the inner edge, and the tooth peak extends from the inner edge to the outer edge to form a convex strip.Type: GrantFiled: August 5, 2020Date of Patent: August 22, 2023Assignee: GENIUS ELECTRONIC OPTICAL (XIAMEN) CO., LTD.Inventors: Junjiao Chen, Jianhai Huo, Shang-Hao Su, Qingshu Ye

Patent number: 11460612Abstract: A spacer, including a spacer body, a light transmissive film, and a light absorbing film, is provided. The spacer body has an outer side surface, an inner inclined surface, an object side surface, and an image side surface. The object side surface faces an object side and connects the outer side surface with the inner inclined surface. The image side surface faces an image side and connects the outer side surface with the inner inclined surface. The inner inclined surface is located between an optical axis of the spacer and the outer side surface, and includes an inner edge adjacent to the optical axis and an outer edge away from the optical axis. The inner edge forms a light through hole. The light transmissive film and the light absorbing film are disposed on the inner inclined surface. All surfaces facing the optical axis are inclined relative to the optical axis.Type: GrantFiled: July 31, 2020Date of Patent: October 4, 2022Assignee: GENIUS ELECTRONIC OPTICAL (YIAMEN) CO., LTD.Inventors: Ziwen Xu, Junjiao Chen, Haibin Zhan
