TY - JOUR PY - 2015// TI - Fall detection algorithm in energy efficient multistate sensor system JO - Conference proceedings - IEEE engineering in medicine and biology society A1 - Korats, Gundars A1 - Hofmanis, Janis A1 - Skorodumovs, Aleksejs A1 - Avots, Egils SP - 4974 EP - 4977 VL - 2015 IS - N2 - Health issues for elderly people may lead to different injuries obtained during simple activities of daily living (ADL). Potentially the most dangerous are unintentional falls that may be critical or even lethal to some patients due to the heavy injury risk. Many fall detection systems are proposed but only recently such health care systems became available. Nevertheless sensor design, accuracy as well as energy consumption efficiency can be improved. In this paper we present a single 3-axial accelerometer energy-efficient sensor system. Power saving is achieved by selective event processing triggered by fall detection procedure. The results in our simulations show 100% accuracy when the threshold parameters are chosen correctly. Estimated energy consumption seems to extend battery life significantly.
