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.

Abstract: The present invention allows for non-invasive monitoring of the blood sugar levels in diabetic patients. At least one heat and waterproof applicator is applied to the skin surface by a dosage pressure. Temporal dynamics of physiological parameters of the local tissue region are measured under the applicator. Temporal dynamics of climatic parameters of the environment are measured simultaneously or before the beginning of measurement of physiological parameters in the monitoring mode. Further, enthalpy of tissue is calculated with account for the influence of climatic parameters. Magnitude of thermal effect of metabolism of the local area of living tissue is calculated on the basic thermodynamics equation, connecting enthalpy of tissue with variables of thermodynamic state. Relative changes in the level of glucose are calculated in blood, proportional to the value of the thermal metabolism of the local area of living tissue.

Abstract: A method and system including a monitoring device to detect, during a session, a set of radar signals associated with first respiratory-related movements of a first person and second respiratory-related movements of a second person located within a detection zone comprising at least a portion of a bed. The method and system dynamically generate an out-of-bed zone adjacent to a side of the bed. The out-of-bed zone is monitored to detect motion within the zone to determine when the first person exits and enters the bed. The method and system identify a portion of the set of radar signals collected during a time period when the first person is determined to be out of the bed. The identified portion of the set of radar signals is removed from the set of radar signals collected during the sleep session.

Abstract: A system for augmenting uterine forces includes a medical apparatus having a balloon body that transitions between a compacted state and an expanded state, a catheter that receives the medical apparatus and obtains electrical signals indicative of intrinsic uterine contractions, and a controller coupled to the catheter to receive the electrical signals, and to a source of an agent. The controller processes the electrical signals to detect an onset of an intrinsic uterine contraction, an increase in uterine contraction forces, or a decrease in uterine contraction forces. In response to a detection of an onset of an intrinsic uterine contraction or an increase in uterine contraction forces, the controller causes an agent to be delivered from the agent source to the balloon body to expand the balloon body. In response to a detection of a decrease in uterine contraction forces, the controller causes agent to discharge from the balloon body to collapse the balloon body.
