First claim
Opening claim text (preview).
What is claimed: 1. A fuel storage system comprising: a storage vessel including a dielectric liner; a voltage sensor formed by a pair of plates disposed on opposing surfaces of the liner; and a controller configured to determine a gas pressure in the storage vessel based on voltages measured by the sensor. 2. The system of claim 1 wherein the controller is further configured to determine a capacitance of the sensor based on the voltages measured by the sensor. 3. The system of claim 2 wherein the controller is further configured to determine a distance between the plates based on the capacitance of the sensor. 4. The system of claim 1 wherein one of the plates is electrically grounded. 5. The system of claim 1 wherein the plates are electrically conductive. 6. A fuel storage system comprising: a storage vessel including a dielectric liner; a first sensor formed by a first pair of plates disposed on opposing surfaces of the liner; a second sensor formed by (i) a second pair of plates disposed on opposing surfaces of the liner and (ii) a thermistor disposed within the storage vessel and electrically connected with one of the second pair of plates; and a controller configured to determine a gas temperature in the storage vessel based on respective voltages across the first and second sensors. 7. The system of claim 6 wherein the controller is further configured to determine a capacitance of the first sensor based on the voltage across the first sensor. 8. The system of claim 7 wherein the controller is further configured to determine a distance between the first pair of plates based on the capacitance of the first sensor. 9. The system of claim 8 wherein the controller is further configured to determine a gas pressure within the storage vessel based on the distance between the first pair of plates. 10. The system of claim 6 wherein the controller is further configured to determine a resistance of the thermistor based on the voltage across the second sensor. 11. The system of claim 6 wherein one of the first pair of plates is electrically grounded. 12. The system of claim 6 wherein the one of the second pair of plates is electrically grounded via the thermistor. 13. The system of claim 6 wherein the first pair of plates are electrically conductive. 14. The system of claim 6 wherein the second pair of plates are electrically conductive. 15. A method for detecting a gas pressure within a storage vessel having a dielectric liner comprising: measuring a voltage over time across a sensor formed by a pair of metal plates disposed on opposing surfaces of the liner; and determining a gas pressure within the storage vessel based on the measured voltage across the sensor. 16. The method of claim 15 wherein determining a gas pressure within the storage vessel based on the measured voltage across the sensor includes determining a capacitance of the sensor based on the measured voltage across the sensor. 17. The method of claim 16 wherein determining a gas pressure within the storage vessel based on the measured voltage across the sensor includes determining a thickness of the dielectric liner based on the capacitance of the sensor.
