  • Publication number: 20190188727
    Abstract: A disassemble monitoring device of an electronic device includes a detecting unit, a one time programmable register, a storage, and a processor. The detecting unit is configured to detect whether the electronic device has been disassembled, and upon detecting that the electronic device has been disassembled, generate a detection signal. The one time programmable register is electrically coupled to the detecting unit and is configured to change a storage value of the one time programmable register in response to the detection signal. The storage value can only be changed once. The processor retrieves the storage value from the one time programmable register in response to a user operation and determines whether the storage value has been changed. Upon determining that the storage value has been changed, the processor confirms a result of determination that the electronic device has been disassembled and outputs the result of determination.

  • Patent number: 10297240
    Abstract: A system for image production in a KTV setting uses more than one display screen, a first screen for displaying a star MV and a song menu and a second screen for images of a singer as captured by cameras within the KTV setting. The system includes a capturing unit and a processing unit. The capturing unit captures images of the singer. The processing unit produces a singer MV according to the images of the single or plurality of singers, which can be enhanced with special effects, and displays the singer MV on the second screen.

  • Patent number: 10271445
    Abstract: A casing of an electronic device includes a shell composed of a number of unit bodies arranged in a number of unit body layers. Each of the unit bodies is a hollow structure including a main portion and two end portions. The two end portions are located at opposite ends of the main portion. The main portion is a hollow hexagonal column. Each of the end portions includes three rhomboid faces extending from the main portion and forming a tip. The unit body layers are arranged such that the tips are staggered.

  • Patent number: 10249188
    Abstract: A method applied to a pedestrian user terminal for road safety includes detecting whether a display device of the user terminal is in an active mode when predetermined signals are received by the user terminal. A prompt can be transmitted when the display device is in the active mode thus providing a warning to the pedestrian user to cross the road, on the display device he or she is viewing. The display device is deactivated when the display device is determined to be still in the active mode after a predetermined time period that starts from the prompt is transmitted.

  • Publication number: 20180307541
    Abstract: A method for analyzing a motherboard for detecting an abnormally heated element of the motherboard includes placing the motherboard in a sealable container and powering on the motherboard, adjusting a temperature inside the sealable container to a predetermined temperature/temperature range, capturing a first image of the motherboard under ultraviolet light, capturing a thermal image of the motherboard, calibrating a position of the first image and the thermal image, combining the calibrated first image and the calibrated thermal image into a second image, and carrying out differential and image binarization processing on the second image and a template image to identify an abnormally heated element of the motherboard. A motherboard analysis device is also provided.

  • Patent number: 10015371
    Abstract: An electronic device able to receive a target frame for tracking a moving target which is included in a search reference sets at least one first detecting region in the target frame. The processor determines similarities between the search reference and the at least one first detecting regions. Then, the processor determines a specific first detecting region in the target frame and determines an actual position of the moving target based on the specific first detecting region.
