Abstract
A monitoring method is performed by a digital processor while a subject is asleep or with little movement. The method includes receiving transducer signals for a subject and training a model for characteristics of a subject or subject group. The model is used in generating sleep data according to real-time correspondence and values of transducer signals including subject rib displacement, subject abdomen displacement, subject torso movement, and subject orientation. Combinations of the transducer inputs are used to determine features from which outputs such as an AHI score are determined. A feature matrix is normalized based on dynamically-generated positional epochs bordered by subject movements to new positions and used to provide a normalization matrix.
