Abstract
A system and method is provided for detection of a human body fall event. The fall detection system () includes a monitoring unit (), including a plurality of accelerometers (), a processor () and a wireless transmitter (). The plurality of accelerometers () provide acceleration measurements to the processor (), the measurements describing the current acceleration of the person wearing the monitoring unit () in all directions. The processor () receives the acceleration measurements and compares the acceleration measurements to a value range to determine if the wearer is currently experiencing a fall event. The processor () generates a signal in response to the detection of a fall event and the transmitter () transmits the signal to a remote signal receiver (). The system and method can further detect non-movement in the wearer of the monitoring unit () subsequent to the fall event to detect an unconscious wearer.
