  • Stress model based on RR integral average
    Patent number: 9301695
    Abstract: A method of determining stress includes receiving a data signal including multiple consecutive RR intervals of a subject. The method may also include calculating heart rate variability (HRV) data for the subject from the data signal. The method may also include calculating an RR integral average (RRIA) from the HRV data, the RRIA indicating a stress level of the subject.

  • Frequency domain analysis transform of renal blood flow doppler signal to determine stress levels
    Patent number: 9168020
    Abstract: A method of determining stress based on renal blood flow. The method includes receiving data indicating renal blood flow of a subject. The method also includes calculating a power spectrum of a signal derived from the data. The power spectrum indicates a stress level of the subject.

  • Calculating and monitoring the efficacy of stress-related therapies
    Patent number: 8622900
    Abstract: In particular embodiments, a method includes accessing data streams from at least two of an accelerometer, a heart-rate monitor, a blood-pressure monitor, a pulse oximeter, or a mood sensor monitoring a person, analyzing data sets collected from the person when the person is engage and not engaged in a therapy, and determining a current stress factor for the therapy on the person based on the analysis.
