  • Publication number: 20250032011
    Abstract: This document describes techniques and devices for blood-solute calculation with a mobile device using non-invasive spectroscopy. A mobile device includes a light source that emits light toward an interferometer that uses mirrors to separate and recombine the light. The interferometer directs the recombined light toward a person. Light reflected from, or transmitted through, the person is received through a reception port to a photodetector that outputs photodetector data that corresponds to a measured light intensity of the reflected and transmitted light as a function of a path length of the light or a mirror position of the interferometer. Based on the photodetector data, an interferogram is generated. Applying a technique such as a Fourier transform to the interferogram, a spectrum data set of the reflected and transmitted light is generated. Based on the spectrum data set, a concentration of solutes in the person's blood is calculated.

  • Publication number: 20240423512
    Abstract: The present disclosure provides computer-implemented methods, systems, and devices for non-invasively measuring a level of an analyte in a user using Stimulated Raman Scattering. A user computing device includes a Raman pump source that emits pump light toward a skin surface of the user at a pump wavelength. The device includes a Stokes source that emits Stokes light toward the skin surface at a plurality of Stokes wavelengths within a window of Raman measurement wavelengths. The Stokes light comprises a plurality of narrowband emissions at a respective plurality of center wavelengths ranging across the window of Raman measurement wavelengths. The device includes a photodetector that measures light that emanates from the skin surface. The device includes a processor that processes the measured light to provide an estimated analyte level of the user.

  • Patent number: 12150759
    Abstract: This document describes techniques and devices for blood-solute calculation with a mobile device using non-invasive spectroscopy. A mobile device (502) includes a light source (504) that emits light toward an interferometer (508) that uses mirrors to separate and recombine the light. The interferometer directs the recombined light toward a person. Light reflected from, or transmitted through, the person is received through a reception port (506) to a photodetector (510) that outputs photodetector data that corresponds to a measured light intensity of the reflected and transmitted light as a function of a path length of the light or a mirror position of the interferometer. Based on the photodetector data, an interferogram is generated. Applying a technique such as a Fourier transform to the interferogram, a spectrum data set of the reflected and transmitted light is generated. Based on the spectrum data set, a concentration of solutes in the person's blood is calculated.
