  • Patent number: 9454415
    Abstract: In accordance with one aspect of the present description, an indication that a communication failure reported in a predetermined time interval is more likely the result of a software failure than a hardware failure may be made if the number of communication links reporting a communication failure in the predetermined time interval exceeds a communication link failure threshold, and the number of communication link devices such as nodes or communication paths which have been implicated as causing a communication failure, exceeds an implicated device threshold. Other features and aspects may be realized, depending upon the particular application.

  • Patent number: 9262982
    Abstract: A timing controller for a liquid crystal panel and a timing control method thereof are provided. The timing controller includes a timing control unit for analyzing an input signal to generate a system state transition voltage (STV) signal and a base STV signal, and the timing control unit outputs a base trigger signal and a switch trigger signal having asynchronous frame rates to a select unit at the same time. A compare unit determines whether frequencies of the two state signals are same, so that the select unit determines to forward the base trigger signal or the switch trigger signal to a level shift circuit. Finally, a signal-time control unit controls an output time of the base trigger signal, and controls an output time of the switch trigger signal, so that a liquid crystal unit connected to each gate line has an equal charge time.

  • Patent number: 8749506
    Abstract: A noise cancellation circuit includes at least one antenna, a multiplexer, and a readout circuit. The at least one antenna is used for coupling noise of a touch panel and noise of a liquid crystal panel coupled to the touch panel. The multiplexer is used for receiving first X axis sensing signals and first Y axis sensing signals of the touch panel. The readout circuit is used for utilizing the noise of the touch panel and the noise of the liquid crystal panel to cancel noise of the touch panel and noise of the liquid crystal panel in the first X axis sensing signals and the first Y axis sensing signals, and to generate and output second X axis sensing signals and second Y axis sensing signals not including the noise of the touch panel and the noise of the liquid crystal panel.

  • Patent number: 8654107
    Abstract: A shading signal generating circuit includes an output port, a first switch, a second switch, a third switch, a first control unit, a second control unit, and a resistor. The output port is electrically connected to the first switch, the second switch, and the third switch. The first switch is electrically connected to a first voltage source and switched on according to a clock signal. The second switch is electrically connected to a second voltage source. The first control unit converts the clock signal to an inverse clock signal, thereby outputting a switch signal for switching on the second switch. The resistor is connected between a third voltage source and the third switch in series. The third switch controls the electric connection between the output port and the third voltage source. The second control unit switches on the third switch according to the inverse clock signal and the switch signal.
