Patent ID: 7549435

Claim:
A system for automatically detecting and correcting a fluid leak, the system comprising: a sensor configured to provide a first voltage level when exposed to a fluid flowing from a fluid source, wherein the sensor is further configured to provide a second voltage level when not exposed to the fluid; a valve module having at least one valve that is selectively switchable between an open position to allow fluid flow from the fluid source and a closed position to substantially arrest fluid flow from the fluid source; an adjustable resistance device configured to provide a voltage threshold; feedback circuitry configured to output a feedback voltage indicative of the position of the at least one valve; and a processor coupled to the sensor, the valve module, the adjustable resistance device and the feedback circuitry, wherein the processor is configured to output a first control signal to cause the valve module to close the at least one valve when the sensor is providing the first voltage level and the feedback voltage has not attained the voltage threshold, and wherein the processor is configured to output a second control signal to cause the valve module to open the at least one valve when the sensor is providing the second voltage level and the feedback voltage has not attained the voltage threshold.
