    Abstract: Optical coherence tomography (herein “OCT”) based analyte monitoring systems are disclosed. In one aspect, techniques are disclosed that can identify fluid flow in vivo (e.g., blood flow), which can act as a metric for gauging the extent of blood perfusion in tissue. For instance, if OCT is to be used to estimate the level of an analyte (e.g., glucose) in tissue, a measure of the extent of blood flow can potentially indicate the presence of an analyte correlating region, which would be suitable for analyte level estimation with OCT. Another aspect is related to systems and methods for scanning multiple regions. An optical beam is moved across the surface of the tissue in two distinct manners. The first can be a coarse scan, moving the beam to provide distinct scanning positions on the skin. The second can be a fine scan where the beam is applied for more detailed analysis.

  • Patent number: 11141069
    Abstract: A method for increasing accuracy of measurement of body temperature includes a step of collecting an infrared signal to obtain an infrared signal value (step 1), a step of collecting a skin image to obtain a calibrating emissivity (step 2), a step of obtaining a calibrated infrared signal value according to the calibrating emissivity and the infrared signal value obtained in step 1 (step 3), and a step of making a conversion into an actual body temperature (step 4). Accordingly, an actual temperature value of the skin surface can be attained to increase the accuracy of measurement effectively, thereby allowing the measured result to be more close to the real body temperature of a tested target.
