  • Patent number: 10222260
    Abstract: An approach to noninvasively and remotely detect the presence, location, and/or quantity of a target substance in a scene via a spectral imaging system comprising a spectral filter array and image capture array. For a chosen target substance, a spectral filter array is provided that is sensitive to selected wavelengths characterizing the electromagnetic spectrum of the target substance. Elements of the image capture array are optically aligned with elements of the spectral filter array to simultaneously capture spectrally filtered images. These filtered images identify the spectrum of the target substance. Program instructions analyze the acquired images to compute information about the target substance throughout the scene. A color-coded output image may be displayed on a smartphone or computing device to indicate spatial and quantitative information about the detected target substance.

  • Patent number: 10222324
    Abstract: A non-destructive method of estimating hematocrit (Hct) of whole blood from a dried blood sample prepared from the whole blood, the method comprising: a) determining the amount of hemoglobin derivatives comprising oxyhemoglobin, met-hemoglobin and hemichrome (total hemoglobin) in a dried blood sample, wherein the sum of the amounts of the hemoglobin derivatives remains constant in the dried blood sample in function of time, and b) estimating the hematocrit from the sum of the amounts of the hemoglobin derivatives, wherein the hematocrit is estimated using a calibration curve providing a correlation between hematocrit and the amount of the hemoglobin derivatives in a dried blood sample. The amount of the hemoglobin derivatives is preferably determined by measuring the reflectance, absorbance, or transmittance of the dried blood sample at the quasi-isosbestic point of the hemoglobin derivatives about 589 nm or at multiple wavelengths within the range of 450 to 750 nm.

  • Patent number: 10213113
    Abstract: A wearable device includes a measurement device adapted to be placed on a wrist or ear having a light source with LEDs to measure physiological parameters. The measurement device generates an optical beam having a near infrared wavelength between 700-2500 nanometers by modulating the LEDs, and lenses to deliver the beam to tissue, which reflects the beam to a receiver having spectral filters in front of spatially separated detectors coupled to analog to digital converters that generate at least two receiver outputs. Signal-to-noise ratio of the beam reflected from the tissue is improved by comparing the receiver outputs, and by increasing light intensity from the LEDs. The receiver is synchronized to the modulation of the LEDs and uses a lock-in technique that detects the modulation frequency. The measurement device generates an output signal representing a non-invasive measurement on blood within the tissue.
