  • Luminous intensity test device
    Patent number: 8902415
    Abstract: A luminous intensity test device includes an optical frequency converter, a display, and a processor. The optical frequency converter selectively converts at least a portion of light emitted by a light source into a digital signal. The display displays a color selection interface. The processor processes the digital signal and obtains the luminous intensity. When a tester inputs a color parameter into the color selection interface via an input device, the optical frequency converter converts a kind of light to the digital signal and then the processor processes the digital signal to obtain a luminous intensity and display the luminous intensity on the display.

  • ELECTRONIC DEVICE AND METHOD FOR PROMPTING OVERTIME USAGE OF ELECTRONIC DEVICE
    Publication number: 20130258074
    Abstract: An electronic device includes an image capturing unit and a processor. The image capturing unit captures image of a front of the electronic device. The processor periodically controlling the image capturing unit to capture the image of a front of the electronic device, determines whether a user begins to use the electronic device according to the image captured by the image capturing unit, begins to time if the user begins to use the electronic device, and generates a prompt if the timed time reaches to a predetermined time.
