  • Patent number: 10141925
    Abstract: A circuit for strengthening load transient response compensation is provided, including a comparator, a first MOSFET and a second MOSFET. The comparator compares a system voltage of an electronic device with a reference voltage. The first MOSFET is coupled to the comparator and a first power supply. The second MOSFET is coupled to the comparator and a second power supply of the electronic device. When an external device is connected to the electronic device such that the system voltage is lower than the reference voltage, the comparator outputs a low-level signal and the first MOSFET becomes conductive, so that the external device is powered by the first power supply.

  • Patent number: 10120637
    Abstract: A mirror display system having low data traffic comprises a transmitting-end device and a receiving-end device. The transmitting-end device stores a first file and transforms the first file into the first page images. The receiving-end device stores a second file with same content of the first file and transforms the second file into the second page images. The transmitting-end device selects one of the first page images according to a page-selecting operation, and transmits an identifying page data of the selected first page image to the receiving-end device. The receiving-end device selects and displays one of the second page images corresponding to the identifying page data. With pre-storing the file duplicate in the receiving-end device and the receiving-end automatically generating the image, the required data traffic of the mirror display is effectively reduced and the mirror display operation is made smoother.
