  • Method and apparatus for protecting a money-handling unit vulnerable to liquid
    Patent number: 6000520
    Abstract: A control circuit of a money-handling unit receives an input from a coin sensor, and detects whether liquid is present by detecting the occurrence of a false signal caused by liquid shorting the output of the sensor. Two different thresholds of conductivity can be used to detect whether liquid is present and to distinguish between high conductivity liquids and low conductivity liquids. The control circuit carries out different courses of action to respond to the liquid depending on the conductivity. Either a temporary or permanent shut down is selected.
