Patent ID: 8448665

Claim:
A fuel overflow alarm system, comprising: a fuel tank; a fuel inlet conduit provided in fluid communication with the fuel tank; at least one fuel splash valve provided in the fuel inlet conduit; a pressure-sensing tube provided in fluid communication with the fuel tank; a pressure sensor provided in fluid communication with the pressure-sensing tube; a microcontroller interfacing with the pressure sensor and the at least one fuel splash valve, the microcontroller adapted to automatically terminate dispensing of fuel into the fuel inlet conduit by closing the at least one fuel splash valve responsive to input from the pressure sensor; a fuel gauge connected to the microcontroller; a vent conduit provided in fluid communication with the fuel tank and at least one valve provided in the vent conduit and interfacing with the microcontroller; and at least one accelerometer interfacing with the microcontroller, the microcontroller adapted to close the at least one valve provided in the vent conduit responsive to sensing of movement by the at least one accelerometer.
