  • Patent number: 11938322
    Abstract: Embodiments in accordance with the present disclosure are directed to methods and apparatuses used for slow wave activity (SWA) optimization. An example method includes receiving one or more bio-signals from a user and classifying sleep stages by processing the bio-signals. The method further include determining dominant peripheral nervous system (PNS) oscillations based on the bio-signals and as a function of time and stage of sleep, and characterizing at least one property of the dominant PNS oscillations, including a phase, a phase shift, an amplitude, and/or frequency. The method further include providing an indication of an optimal window for maximizing SWA generation based on the phase, the phase shift, the amplitude, or the frequency. The indication is provided to stimulation circuitry that delivers stimulation to the user within the optimal window. Feedback is provided responsive to the stimulation based on an EEG signal of the user.

  • Patent number: 11804301
    Abstract: Embodiments in accordance with the present disclosure are directed to systems and methods for managing hot flashes and/or menopause symptoms. An example system includes sensor circuitry and logic circuitry. The sensor circuitry obtains a physical measurement associated with a user and communicates the physical measurement. The logic circuitry generates a predictive model that indicates a probability of the user having a hot flash at a date and time based on a plurality of input parameters, revises the probability based on the physical measurement using the predictive model, and communicates data indicative of an action in response to the revised probability being outside a threshold, such as providing cooling relief.

  • Publication number: 20120283583
    Abstract: Apparatus, method, and software for electrocardiogram-assisted non-invasive arterial blood pressure d stiffness measurement is disclosed including brachial cuff with flexible electrodes, control box with rigid electrodes, and associated hardware/software. Cuff is wrapped around upper arm while electrodes on device are touched with fingers of other hand. Device acquires simultaneous ECG/oscillometric data during cuff deflation. Processing unit determines ECG R-peak positions to isolate arterial pulses and calculate pulse transit time. Change in pulse amplitude as function of cuff pressure is used for constructing oscillometric envelope and calculating blood pressure using empirical coefficients. Change in pulse transit time as function of cuff pressure is used independently for constructing pulse transit time envelopes and finding blood pressure with/without empirical coefficients. Fusion algorithm combines results for robust blood pressure and vessel stiffness evaluation.
