  • Patent number: 10063022
    Abstract: A power distribution unit is connected to a three-phase electric power source having three phase wires with different phases, and includes a socket and a switch. The socket has a first socket terminal connected to one of the phase wires, and a second socket terminal. The switch includes a first switch terminal connected to another one of the phase wires, a second switch terminal connected to a neutral, and a third switch terminal connected to the second socket terminal. By selectively connecting the third and the first switch terminals, or connecting the third and the second switch terminals, a line-to-neutral voltage or a line-to-line voltage from the three-phase electric power source is outputted by the socket.

  • Patent number: 10008171
    Abstract: A gate driving circuit is provided. The gate driving circuit includes multistage driving modules, where an Nth stage driving module includes a setting circuit, a first driving circuit, an isolating switch circuit, a second driving circuit and an anti-noise circuit. The setting circuit generates a first precharge signal according to a gate driving signal of an (N?2)th scan line or a start signal. The isolating switch circuit coupled between the first driving circuit and the second driving circuit provides a second precharge signal, so as to effectively avoid a flickering problem of a display image caused by a surge of the gate driving signal due to a coupling effect of a parasitic capacitance of the transistor and a bootstrap capacitor, and meanwhile the bootstrap capacitor is not used, so as to effectively reduce a bezel area.

  • Publication number: 20170230231
    Abstract: In one embodiment of the invention, a redundancy system/method based on the Virtual Router Redundancy Protocol, it includes a master router and at least one backup router preselected. The master router and at least one backup router may have a weight value and Virtual LANs composed of same routing path. A communication representative is chosen from one of the Virtual LANs of each of the master router and the backup router. The communication representative of the master router may continuously transmit the advertisement packet to that of the backup router, and continuously transmit an Address Resolution Protocol table to the backup router. When a communication representative of the backup router doesn't receive the advertisement packet, all the Virtual LANs of the master router will be judged abnormal, and the master router may be replaced, therefore enhance the redundancy switching efficiency and increase the number of the available Virtual LANs.
