  • Patent number: 11931142
    Abstract: Aspects of the present disclosure are directed to detecting apneic and/or hypopneic events, utilizing a physiological signal. Various apparatuses and/or methods involve computing time series of interbeat intervals are from data characterizing activity of a beating heart, decomposing the time series is into subcomponents, and identifying ones of the subcomponents that relate to a portion of the data during which an apneic and/or hypopneic, as may be detected via oximetry. Once identified, these subcomponents and related formula/weighting can be utilized in computing further subcomponents from the data, and identifying further apneic and/or hypopneic events therefrom. In this context, such events may be detected without necessarily involving further use of oximetry.

The quality value is calculated from reflectance data received at the detectors of the oximeter device. An accelerometer of the oximeter device can detect movement of the oximeter device when oximetry measurements are made by the oximeter device. An amount of the movement is an indicator of a probe face of the oximeter device changing position with respect to the tissue when the measurements are made. The accelerometer information is used by the oximeter device to adjust the quality value to reflect the amount movement. The oxygen saturation and the adjusted quality metric value are displayed on a display of the oximeter device so that a user may view the quality of the displayed information.

  • Patent number: 11666227
    Abstract: This disclosure relates to selection of optimum channel in twin radars for efficient detection of cardiopulmonary signal rates. State-of-the-art solutions involve use of IQ (In-phase and Quadrature) channel radar which need continuous calibration. Distance of the radar from a subject being monitored affects performance. The present disclosure enables enhanced cardiopulmonary signal rate monitoring using a time domain approach, wherein only the data from signal reflected off the radar is considered. The solution is also time window adaptive. Signal property and radar physics-based methods have been implemented for selecting an optimum channel in twin radars thereby enhancing detection of respiration rate and breath rate.
