METHOD AND SYSTEM OF SEGMENTATION AND TIME DURATION ANALYSIS OF DUAL-AXIS SWALLOWING ACCELEROMETRY SIGNALS

摘要

The proposed invention is a method and system for the segmentation of dual-axis accelerometrysignals for the purpose of identifying problematic swallowing events. Themethod and systememploy a sensor, a data collection means including an algorithm for analysisof the data. Theproposed invention considers the stochastic properties of swallowing signalsin both directions,A-P and S-I to extract events associated with swallowing. A segmentationalgorithm may beapplied to the signals to establish the time duration of swallows and swallowsmay be classifiedwith respect to gender, body mass index, age or types of swallow.
