  • Patent number: 10782284
    Abstract: A breath analyte capture device includes a breath input port into which a user exhales a breath sample, and a cartridge insertion port for receiving a disposable cartridge containing an interactant. During exhalation of a breath sample, at least a portion of the breath sample is routed through the cartridge such that the analyte (such as breath acetone) is captured by the interactant. In some embodiments, the concentration of the analyte in the breath sample is measured by monitoring a chemical reaction that occurs in the disposable cartridge. The chemical reaction may be monitored by illuminating the cartridge at each of multiple light wavelengths while measuring reflected light.

  • Patent number: 10746655
    Abstract: Detector data representative of an intensity of light that impinges on a detector after being emitted from a light source and passing through a gas over a path length can be analyzed using a first analysis method to obtain a first calculation of an analyte concentration in the volume of gas and a second analysis method to obtain a second calculation of the analyte concentration. The second calculation can be promoted as the analyte concentration upon determining that the analyte concentration is out of a first target range for the first analysis method.

  • Patent number: 10724941
    Abstract: A liquid membrane 100 is formed by jetting a liquid sucked from a recovery reservoir 11a and pressurized using a pump 12 from a nozzle of a liquid membrane cartridge 20. The formed liquid membrane 100 makes contact with a slope wall of the liquid membrane cartridge 20 along a surface of the liquid membrane 100. The liquid running down from the slope wall is recovered and stored in the recovery reservoir 11a in order to recover the liquid running down along the slope wall in a decelerated state into the recovery reservoir 11a. As a result, it is possible to prevent air bubbles from being generated by agitation of a liquid of the recovery reservoir 11a when the liquid enters the recovery reservoir 11a.

  • Patent number: 10684167
    Abstract: An optical measurement method and system. The system includes, and method applies, a light source, a beamsplitter, at least one filter, a output photodetector for acquiring data of a sample, and a correction photodetector for correcting and maintaining output intensity from the light source. The filter is located between the light source and the correction photodetector for normalizing the spectrum of the input light being applied to input light correction. The filter may be incorporated into the beamsplitter and may be tuned to filter light from the light source for providing non-zero transmission of light with a near-zero gradient for wavelengths in a portion of the spectrum of the input light being applied to the sample and read by the output photodetector. The filter may also or alternatively be located downstream of the beamsplitter to correct for wavelength sensitivity of the correction photodetector.
