  • Patent number: 11610876
    Abstract: 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.

  • Publication number: 20110055606
    Abstract: 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.
