Patent number: 11610876Abstract: A light conversion device includes a light-emitting unit, a photoelectric conversion unit, and an electroconductive bonding layer. Each of the light-emitting unit and the photoelectric conversion unit includes a first-type region and a second-type region opposite to the first-type region. The electroconductive bonding layer is disposed between the light-emitting unit and the photoelectric conversion unit for connecting the photoelectric conversion unit with the light-emitting unit. When the light conversion device is operated to receive a bias and an external light, the light-emitting unit generates a modulated light having a frequency different from that of the external light.Type: GrantFiled: September 23, 2021Date of Patent: March 21, 2023Assignees: EPISTAR CORPORATION, NATIONAL TSTNG HUA UNIVERSITYInventors: Meng-Chyi Wu, Jyun-Hao Liao, Hsiang-Hui Wang

Publication number: 20110055606Abstract: A computer system including a wireless module and a super IO module is provided. The wireless module communicates with a mobile device to detect whether the mobile device is within a predetermined distance to the computer system. The super IO module electrically coupled to the wireless module manages the status of the computer system based on the distance of the mobile device. If the mobile device moves away from the range of the predetermined distance, the super IO module sends a first management signal to switch the computer system to an inactive state. Conversely, if the mobile device moves into the range of the predetermined distance while the computer system is in an inactive status, the super IO module sends a second management signal to switch the computer system back to a normal operation status or power up the computer system.Type: ApplicationFiled: August 25, 2009Publication date: March 3, 2011Inventors: Meng-Chyi WU, Shih-Hsin Su
