  • Microfluidic based integrated sample analysis system
    Patent number: 10906043
    Abstract: A portable microfluidic system capable of rapid diagnosis is described, which is able to analyze genetic, protein and cell composition of a sample in parallel for specific diseases from a relatively small sample. The method uses a single microfluidic chip integrated into a unique portable microfluidic platform and provides improved diagnostic accuracy, allows for frequent monitoring and is suitable for easy use in clinical settings.

    Assignee: Biomed Canada Corporation
    Inventors: Gong Zhang, Francis Lin, Edward Stewart Richmond, Marshall Ring
  • PPG measurement of arterial health using disease library
    Patent number: 10881309
    Abstract: The arterial health of an individual can be determined by: attaching a fingertip photopiethysmography device to a fingertip of the hand of the elevated arm of the individual; measuring the analog pulse contour of the individual using the fingertip photopiethysmography device; digitizing the analog pulse contour; analyzing the digitized pulse contour for stable waveforms; processing the stable waveforms of the digitized pulse contour using dynamic time warping; comparing the stable waveforms to a library of known disease state waveforms; and assigning a most probable disease state for the individual based on said comparison.
