  • Systems and methods for monitoring subjects in potential hypoxic distress
    Patent number: 11642052
    Abstract: A method of monitoring a subject for the risk of Acute Mountain Sickness (AMS) includes obtaining real-time pulse arterial oxygen saturation (SpO2) measurements from the subject. The SpO2 measurements are transformed into a novel metric known as Accumulated Hypoxic Debt (AHD). The AHD metric is used as the independent variable in a longitudinal generalized linear mixed model to calculate the probability D that the subject is at risk of AMS. Based on the probability D, appropriate courses of action may be communicated to the subject via the output device of a wearable or portable monitor.

  • Renaturation of proteins
    Patent number: 6022722
    Abstract: The invention relates to a method for the renaturation of denatured proteins in which they are treated with a renaturant which has on vicinal carbon atoms a hydroxyl group and at least one fluorine atom.
