  • Method for finding disconnection of conductive wires formed on plate glass and apparatus therefor
    Patent number: 7332718
    Abstract: The invention relates to a method for finding disconnection of a conductive wire formed on a plate glass. This method includes the steps of (a) applying a voltage to the conductive wire; and (b) imaging thermal radiation from a surface of the conductive wire by an infrared image sensor, while the step (a) is conducted, thereby producing a temperature distribution image. An apparatus for conducting the method includes (a) a power source for applying a voltage to the conductive wire; and (b) an infrared image sensor for imaging thermal radiation from a surface of the conductive wire, thereby producing a temperature distribution image.
    Type: Grant
