Abstract
A system and a method for detecting if a person has fallen down is provided. The system includes at least two sensors which remotely detect energy in at least two zones. The output of the sensors are analyzed and compared to characteristics which are determined to be representative of a fall. If the sensor outputs match the particular characteristics, the system concludes that a fall has occurred and outputs this result. An alarm may be generated if the system detects a fall.
