Abstract: A universal canister flush valve having a valve body configured to be fixed relative to a toilet tank and having a hollow wall defining an internal flow passage; a guide post coupled to and extending away from the valve body; a float fitted about and configured to slide relative to the guide post between a closed position and an open position, the float having an open top; and an extender that selectively couples to the open top in a first position, in which a first end of the extender is received in and coupled to the open top, and in a second position, in which a second end of the extender is received in and coupled to the open top, wherein the extender and float define a first overflow height in the first position and define a second overflow height in the second position.

Abstract: A system and method of verifying the identity of a user or registrant. The user or registrant provides identification information and registration information. The identification information may be a visual representation of an identifying item associated with location information. In some embodiments, the identification information may be a visual representation of a government issued identity. An identification module verifies the identification information and compares the verified identification information to the registration information.

Abstract: A fuel cell temperature-measuring system includes a coolant source that provides coolant at a total coolant flow rate and an initial coolant temperature. A flow field plate defines peripheral flow channels and active area flow channels through which coolant flows. The flow field plate is adapted to be positioned in a fuel cell stack between individual fuel cells. A total coolant flow provided to the common input divides into a bypass flow that flows through the peripheral flow channels and an active area flow that flows through the active area flow channels. The bypass flow combines with the active area flow to emerge from the common output with an output coolant temperature. The fuel cell temperature-measuring system includes a temperature sensor that measures the output coolant temperature from the common output. Finally, a temperature estimator estimates an active area coolant temperature from the output coolant temperature.

Abstract: A fuel cell voltage recovery system includes a fuel cell stack having a fuel cell stack voltage between fuel cell stack terminals which is at a first voltage during normal fuel cell operation. The system also includes a high voltage electrical system operating at a first DC operating voltage that is generally higher than the first voltage of the fuel cell stack. A boost converter in electrical connection with the fuel cell stack and the high voltage electrical system operates in a normal control mode to transfer electrical power from the fuel cell stack to the high voltage electrical system through regulation and control of average stack output current (boost input current) during normal fuel cell operation. The boost converter can also operate in a voltage control mode to lower the fuel cell stack voltage to a second voltage that is lower than the first voltage. A FCS controller controls the operation of the boost converter.
