International Classification:

G01R 27/08
H03B 19/00

US Classification:

324693, 327113

Abstract:

A measurement circuit that has particular application for detecting a high impedance measurement signal from a liquid water sensor. The measurement circuit includes a high impedance resistance-to-frequency conversion circuit that is coupled to the sensor and receives a resistance signal therefrom. The resistance-to-frequency conversion circuit includes an oscillator that converts the resistance signal to a representative frequency. The measurement circuit also includes a frequency-to-voltage conversion circuit that receives the frequency signal from the resistance-to-frequency conversion circuit, and converts the frequency signal to a representative voltage that provides an indication of water on the sensor.

US Classification:

429432, 429428, 429430, 429433, 429442

Abstract:

A system for communicating measurement data from each fuel cell or a group of fuel cells in a fuel cell stack, including a plurality of fuel cells and a plurality of stack plates, where one stack plate is between each fuel cell and on each end of the stack. The system includes a plurality of embedded smart plates where each embedded smart plate is mechanically and electrically coupled to at least one of the plurality of stack plates, and where each embedded smart plate includes optical transceivers on a top side and a bottom side of the smart plate. The system further includes at least one aggregator device having at least one optical transceiver to initiate a series of communications between the embedded smart plates to determine the location and data collected by each of the smart plates.

US Classification:

320101, 320104, 320138, 320139

Abstract:

A system that monitors fuel cells in a fuel cell group. The system includes a plurality of voltage sensors coupled to the fuel cells in the fuel cell group, where each sensor monitors a different voltage of the fuel cells and where lower priority voltage sensors monitor higher voltages and higher priority sensors monitor lower voltages. The system also includes a plurality of oscillators where a separate oscillator is coupled to each of the sensors. Each oscillator operates at a different frequency where higher frequency oscillators are coupled to lower priority sensors and lower frequency oscillators are coupled to higher priority sensors. A light source that receives frequency signals from the oscillators and switches on and off in response to the frequency signals. A light pipe receives the switched light signals from the light source and provides light signals at a certain frequency at an end of the light pipe.

International Classification:

G01N 27/416

US Classification:

324429

Abstract:

A system and method for monitoring fuel cells in a fuel cell group. The system includes a sensor circuit, such as a voltage sensor circuit, that monitors a condition of the fuel cells. If the sensor circuit detects a low performing cell, then it sends a signal to a tone generator that generates a frequency signal that switches a load into and out of the cell group. A voltage sensor detects the voltage of the cell group including the frequency signal, and sends the detected voltage signal to a tone decoder that decodes the frequency signal to determine that the fuel cells are low performing.

International Classification:

G01R 19/00

US Classification:

324 7611

Abstract:

A method for providing calibration and synchronization pulses in a pulse width modulation (PWM) signal including cell voltage measurement pulses, where the calibration pulses are four calibration pulses having a pattern of a narrow width high voltage pulse followed by a wide width low voltage pulse followed by a narrow width high voltage pulse followed by a wide width low voltage pulse that has a very low probability of occurring in a practical fuel cell system. The method modulates a combined sequence of the voltage measurement signals and the calibration pulses using an inverted saw tooth wave to provide the PWM signal, where a width of the pulses representing the voltage signals are proportional to a width of the pulses representing the calibration pulses.
