Abstract: The present disclosure pertains to a method and system for determining the blood pressure dip of a subject based on features extracted from information generated by an on-body sensor system. The on-body sensor system includes a photoplethysmographic (PPG) sensor and a motion sensor. Blood pressure variation is captured throughout the day and utilized along with determinations of whether a subject is asleep or awake. The blood pressure determinations collected throughout the day, along with determinations of sleep periods, are used to determine a blood pressure dip for the day the on-body sensor system is worn.

Abstract: A device and a signal processing method that can monitor human memory performance by recognizing and characterizing high-gamma (65-250 Hz) and beta (14-30 Hz) band oscillations in the left Brodmann Area 40 (BA40) of the brain that correspond with the strength of memory encoding or correct recall. The signal processing method detects high-gamma and beta band oscillations in the electrical signals recorded from left BA40, and quantifies the spectral content, power, duration, onset, and offset of the oscillations. The oscillation's properties are used to classify the subject's memory performance on the basis of a comparison with the subject's prior human memory performance and the properties of the corresponding oscillations. A report of the subject's current memory performance can be utilized in a closed loop brain stimulation device that serves the purpose of enhancing human memory performance.
