  • Patent number: 10690528
    Abstract: An electrochemical sensor may measure the flow of ions and/or electrochemical species in a solution passing the sensor because the electroactive species will continually come into contact with the electrode and an electric signal will be generated by the combination of diffusion and convection bringing the electroactive species to the electrode. The electric signal measured will vary by concentration of ions and/or electrochemical specie(s) and by flow rate. Flow rate may be measured if the concentration of ions and/or electrochemical specie(s) is known; conversely, the concentration of ions and/or electrochemical species may be measured if the flow rate is known. The sensor may also be used to confirm the delivery of a fluid containing ions and/or electrochemical specie(s).

  • 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: 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: 9981267
    Abstract: The combined value of integrating optical forces and electrokinetics allows for the pooled separation vectors of each to be applied, providing for separation based on combinations of features such as size, shape, refractive index, charge, charge distribution, charge mobility, permittivity, and deformability. The interplay of these separation vectors allow for the selective manipulation of analytes with a finer degree of variation. Embodiments include methods of method of separating particles in a microfluidic channel using a device comprising a microfluidic channel, a source of laser light focused by an optic into the microfluidic channel, and a source of electrical field operationally connected to the microfluidic channel via electrodes so that the laser light and the electrical field to act jointly on the particles in the microfluidic channel.

  • Patent number: 9976994
    Abstract: A system reduces unwanted noise due to pump movement. The system includes a pump including a non-conductive piston extending into a pumping chamber for pumping the sample fluid along an analysis fluid path, a wash chamber, and a seal fluidly separating the pumping chamber from the wash chamber. The system also includes a wash path supplying a wash fluid from a wash reservoir to the wash chamber, an electrical conductor electrically connecting the analysis fluid path to the wash fluid path, and a ground conductor electrically connecting the electrical conductor to ground via a resistor. The electrical conductors and resistor combination between the chambers reduces unwanted noise in the conductivity detector due voltage potentials between the eluent and wash chambers created as the piston moves between the chambers.

  • Patent number: 9939406
    Abstract: A biosensor has an underfill detection system that determines whether a sample of a biological fluid is large enough for an analysis of one or more analytes. The underfill detection system applies an excitation signal to the sample, which generates an output signal in response to the excitation signal. The underfill detection system switches the amplitude of the excitation signal. The transition of the excitation signal to a different amplitude changes the output signal when the sample is not large enough for an accurate and/or precise analysis. The underfill detection system measures and compares the output signal with one or more underfill thresholds to determine whether an underfill condition exists.

  • Patent number: 9907542
    Abstract: A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.
