  • Patent number: 10444208
    Abstract: A method in which a concentration of a chemical species of interest is obtained. The method comprises measuring a property (e.g. the oxidation reduction potential) of a reagent (typically based on a simple single electron redox couple) to obtain a baseline measurement. The reagent is mixed with the solution under test, then the property of the mixture is measured to obtain a post reaction measurement. Then the concentration of the chemical species of interest is determined based on the baseline measurement and the first post reaction measurement, typically by calculating a difference of the baseline measurement and the post reaction measurement, then using the difference and a pre-determined conversion table to determine the concentration of the chemical species of interest.

  • Patent number: 9013170
    Abstract: The present invention has an object to provide a lightning current detection sensor that has a configuration resistant to high voltage and high current in a lightning strike and has high sensitivity and high resolution. In a lightning current detection sensor 10, an insulation-coated wire 22 wound in multiple turns is collectively covered with a base tape 21 and a cover tape 23. Thus, even when the insulation-coated wire 22 is wound in multiple turns to increase sensitivity, a minute area can be detected to increase resolution. Also, with the base tape 21 and the cover tape 23 covering the insulation-coated wire 22 and also a shield portion 12 made of an insulating material and a gap 40 formed between the shield portion 12 and the coil portion 20, a sufficient shielding property is ensured and detection with high accuracy can be performed against high current and high voltage without capacitative coupling.

  • Patent number: 8990034
    Abstract: A health monitoring system for a fuel cell stack using current fuel cell architecture to enable the electronic control unit (ECU) to continue to monitor the health of the fuel cell stack despite a component failure. The system uses an embedded measurement module (EMM) connected to a group of fuel cells in the fuel cell stack to monitor the health of that group of fuel cells. The EMM produces a pulse width modulation signal that is sent to the ECU. A total voltage value for the group of fuel cells is embedded into the calibration signal or end of frame sequence. The ECU uses an algorithm to determine a missing voltage of at least one fuel cell in the event of the component failure of that fuel cell by adding up the cumulative value for each fuel cell reporting their voltage and subtracting that value from the total voltage value found in the end of frame sequence.

    Abstract: A charge detection device includes a dielectric member, a base plate coupled to the dielectric member, and a processing unit coupled to the plate. The dielectric member is representative of at least one material on a location of a vessel and the dielectric member induces an electrostatic potential energy when charged. The plate channels the induced energy through at least a portion of the device. The plate further receives at least one signal that is representative of an electrostatic discharge from a different location of the vessel. The processing unit generates at least one first output of a measurement for the induced energy. The processing unit further generates at least one second output of the presence of the electrostatic discharge to facilitate a correlation between the first and second outputs such that a user is enabled to determine the presence of at least one hazardous charging condition on the vessel.
