  • Patent number: 10871461
    Abstract: A method for accurately measuring the conductivity of substances. This method incorporates two points of measurement that are isolated from each other. Each of these points is in contact with the substance to be measured. A continuous, constant electrical current is passed through the substance at the measurement points by means of an electrical force that is not constant but varies depending upon the amount of electrical force required to maintain the constant electrical current through the substance. This constant current is passed through the substance in two directions. This change in direction is achieved by reversing the polarity of the electrical force across the two measurement points. The time periods for each of the two directions of constant current flow are equal. The amount of electrical force or voltage that is required to maintain this constant amount of current is directly related to the resistance of the substance.

  • Patent number: 10446861
    Abstract: A flowing electrolyte fuel cell system design (DHCFC-Flow) is provided. The use of a flowing oxygen-saturated electrolyte in a fuel cell offers a significant enhancement in the cell performance characteristics. The mass transfer and reaction kinetics of the superoxide/peroxide/oxide ion (mobile oxygen ion species) in the fuel cell are enhanced by recirculating an oxidizing gas-saturated electrolyte. Recirculating oxygen-saturated electrolyte through a liquid channel enhances the maximal current observed in a fuel cell. The use of a oxygen saturated electrolyte ensures that the reaction kinetics of the oxygen reduction reaction are fast and the use of convection ameliorates concentration gradients and the diffusion-limited maximum current density. The superoxide ion is generated in situ by the reduction of the oxygen dissolved in the gaseous electrolyte. Also, a dual porosity membrane allows the uniform flow of fuel (e.g., methane) on the fuel side, without allowing phase mixing.

  • Patent number: 10371707
    Abstract: A method for measuring bilirubin levels in a subject. The method can include the steps of providing a sample to be measured from the subject, wherein the sample comprises bilirubin bound to albumin; adding a release agent to the sample, the release agent configured to release the bound bilirubin from the albumin; measuring electrochemical data of the sample using an electrochemical cell; and determining a total serum bilirubin concentration of the sample using the electrochemical data. This method is capable of providing a simpler, faster, and more robust measurement when compared to traditional bilirubin assay methods.

  • Patent number: 10352887
    Abstract: A method for accurately measuring the electrical conductivity of substances. This method incorporates two points of measurement that are isolated from each other. Each of these points is in contact with the substance to be measured. A continuous, constant electrical current is passed through the substance at the measurement points by means of an electrical force that is not constant but varies depending upon the amount of electrical force required to maintain the constant electrical current through the substance. This constant current is passed through the substance in two directions. This change in direction is achieved by reversing the polarity of the electrical force across the two measurement points. The time periods for each of the two directions of constant current flow are equal. The amount of electrical force or voltage that is required to maintain this constant amount of current is directly related to the resistance of the substance.

  • Patent number: 10324052
    Abstract: A method of extracting complex impedance from selected volumes of the material under test (MUT) combined with various embodiments of electrode sensor arrays. Configurations of linear and planar electrode arrays provide measured data of complex impedance of selected volumes, or voxels, of the MUT, which then can be used to extract the impedance of selected sub-volumes or sub-voxels of the MUT through application of circuit theory. The complex impedance characteristics of the sub-voxels may be used to identify variations in the properties of the various sub-voxels of the MUT, or be correlated to physical properties of the MUT using electromagnetic impedance tomography and/or spectroscopy.

  • Patent number: 10309922
    Abstract: Proposed is a device for detecting a chemical/physical phenomenon, in which, via a novel scheme, charges are accumulated in a charge accumulation region. An amount of charges thus accumulated reflects the potential of a sensing region and the potential corresponds to an external environment (chemical phenomenon or physical phenomenon) to be detected. A charge accumulation region 5 includes a first potential well region FD1 that is continuous with a sensing region 3, the boundary potential of the charges held in the first potential well region FD1 being made equal to the potential of the sensing region 3, whereby the potential of the sensing region 3 is made to be reflected in the amount of charges held in the first potential well region FD1.
