Patent number: 11934027Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.Type: GrantFiled: June 21, 2022Date of Patent: March 19, 2024Assignee: TDK TAIWAN CORP.Inventors: Chao-Chang Hu, Chih-Wei Weng, Chia-Che Wu, Chien-Yu Kao, Hsiao-Hsin Hu, He-Ling Chang, Chao-Hsi Wang, Chen-Hsien Fan, Che-Wei Chang, Mao-Gen Jian, Sung-Mao Tsai, Wei-Jhe Shen, Yung-Ping Yang, Sin-Hong Lin, Tzu-Yu Chang, Sin-Jhong Song, Shang-Yu Hsu, Meng-Ting Lin, Shih-Wei Hung, Yu-Huai Liao, Mao-Kuo Hsu, Hsueh-Ju Lu, Ching-Chieh Huang, Chih-Wen Chiang, Yu-Chiao Lo, Ying-Jen Wang, Shu-Shan Chen, Che-Hsiang Chiu

Publication number: 20210199634Abstract: A rapid detection method of sulfide content is provided, which includes determining the concentration and volume of a metal ion solution, the volume of a sample, and the amount of a chemical reducing agent, depending on a threshold value. It also provides preparing the metal ion solution, sampling the sample, and mixing the metal ion solution with the sample to result in a mixture solution. The chemical reducing agent is added into the mixture solution to obtain the resulting solution. Naked-eye observation of the resulting solution is used to determine whether the sulfide content of the sample is over the threshold value. When the resulting solution is clear, this indicates that the sulfide content of the sample is greater than or equal to the threshold value. When the resulting solution contains precipitates, this indicates that the sulfide content of the sample is lower than the threshold value.Type: ApplicationFiled: December 30, 2019Publication date: July 1, 2021Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Win-Lone LIN, Huan-Yi HUNG, Chien-Wei LU, Han-Wen CHU, Hsiu-Li SU, Yueh-Hsing LI, Chong-You CHEN, Ting-Yu TSAI

Patent number: 10996518Abstract: A light switchable device is provided. The light switchable device includes a first conductive layer, a second conductive layer disposed opposite the first conductive layer, and a sealant layer disposed between the first conductive layer and the second conductive layer. The first conductive layer, the second conductive layer, and the sealant layer form a closed space. The light switchable device also includes a light switchable layer disposed in the closed space, wherein the light switchable layer includes a plurality of alignment structures and polymer-stabilized liquid crystals (PSLC). The plurality of alignment structures is disposed on the first conductive layer or the second conductive layer, and the PSLC's are distributed between the plurality of alignment structures. A height of the plurality of alignment structures is less than a height of the sealant layer, and greater than or equal to 5% of the height of the sealant layer.Type: GrantFiled: December 26, 2019Date of Patent: May 4, 2021Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Tien-Shou Shieh, Chien-Wei Lu, Pei-Hsin Chien, Huan-Yi Hung, Mei-Rurng Tseng

Patent number: 9194856Abstract: method for diagnosing corrosion of an underground storage tank system is provided. The method includes the following steps. A sample from the underground storage tank system is collected, wherein the sample comprises at lease one metal ion. The species and the concentration of the metal ion in the sample are detected by an analysis instrument. A concentration threshold value is determined from a database according to the species of the metal ion. A mapping step is performed, wherein the concentration of the metal ion and the concentration threshold value are compared to diagnose if the underground storage tank system is corroded.Type: GrantFiled: July 10, 2013Date of Patent: November 24, 2015Assignee: Industrial Technology Research InstituteInventors: Pang-Hung Liu, Huan-Yi Hung, Chien-Wei Lu, Han-Wen Chu, You-Zung Hsieh
