An interactive fall and loss of consciousness detector system

A device capable of automatically detecting a fall with loss of consciousness (FloC), and activate an alarm by means of an accelerometer sensor is presented. Four hundred trials were performed by 20 participants (10 young and 10 elderly adults). The algorithm relies on the recognition of the effects of three events characterizing a FLoC: impact of the body against the ground, lying and immobility. All FLoC cases were correctly detected as well as all activities of daily living (ADLs). This result corroborates both usefulness and applicability of the device proposed.
