  • Patent number: 9464891
    Abstract: A method for measuring thickness or defect depth by pulsed infrared thermal wave technology is described. The method includes heating a measured object by pulsed heating devices, and at the same time, obtaining a thermal image sequence on the surface of the measured object by an infrared thermography device, and storing the thermal image sequence in a general-purpose memory. The method also includes multiplying a temperature-time curve at every point of the thermal image sequence by a corresponding time, thereby obtaining a new curve. The method also includes calculating a first-order differential and obtaining a peak time thereof. The method also includes use of one or more formulas to thereby determine the thickness or the defect depth of the measured object.

  • Publication number: 20100134306
    Abstract: A circuit interrupter with end-of-life indicator is provided. A fuse is provided between the power supply and the control chip, and between the power supply and the main circuit. If the current passing through the control chip or the main circuit is drawing too much current, it indicates a short-circuit fault has occurred. In this case, the fuse is melted, and cutting off power supply to the control chip and the main circuit. An end-of-life indicator light turns off to signal to the user that an fault has occurred to the GFCI device.
