    Abstract: The disclosed embodiments provide a system that non-invasively analyzes blood flow in a sample of living tissue. During operation, the system obtains light from a temporally coherent source, and splits the obtained light between a reference path and a sample path. Next, the system multiply scatters light from the sample path by passing the light through the sample. The system then recombines light from the reference path and the multiply scattered light from the sample path. Next, the system uses a sensor array to detect an interference pattern resulting from the recombination. Finally, the system analyzes signals from the sensor array to determine a blood flow in the sample.

    Abstract: A method includes a first acquisition step of acquiring exercise intensity of exercise done by a target person, a second acquisition step of acquiring an electrocardiographic waveform of the target person who does the exercise, a third acquisition step of acquiring a predetermined feature amount from the acquired electrocardiographic waveform, and an estimation step of estimating an AT of the target person based on a relationship between the predetermined feature amount and the acquired exercise intensity. The estimation step includes a step of estimating the AT of the target person based on exercise intensity corresponding to an inflection point in a change of the predetermined feature amount with respect to the acquired exercise intensity.

  • Publication number: 20210030302
    Abstract: An integrated device of a patch and sensor assembly detects extravasation or infiltration. A transmitter is positioned to direct power into a body portion. A sensor is positioned to receive the power transmitted through the body portion. A substrate is attachable to an outer surface of the body portion and supports the transmitter and the sensor. A signal processor is coupled to the transmitter and the sensor for detecting a change in a fluid level in the body portion from extravasation or infiltration based on the power received by the sensor. A power supply is coupled to the transmitter and the sensor. An indicator is responsive to the signal processor to indicate a detected change in a fluid level in the body portion from extravasation or infiltration.

    Abstract: Analysis of a breath sample is a noninvasive point-of-care tool with ever increasing clinical applicability. Herein we describe a method to analyze the content of low-level, trace volatile organic compounds from alveolar breath captured as a breath sample from a patient. The breath sample is then analyzed using a gas phase analysis methodology, such as gas chromatography-mass spectroscopy (“GCMS”), to generate an analysis result, such as a GCMS spectrum. A computer system is then used to develop a fingerprint pattern from the analysis result. The fingerprint pattern is then used to determine a patient status for the patient. The fingerprint pattern is typically a grouping of 75 to 450 compounds of known concentration which are indicative of a particular neurodegenerative disease.
