Abstract
A fall detection system includes a wearable monitoring device that monitors the movement of a person. The device monitors a sensor and detects variation from the normal range and duration thereof. The system determines whether the wearer has fallen through an algorithmic analysis technique using parameters to evaluate the accelerations and timings of the events that comprise a fall. If the combination of the timing and variations from the normal ranges are sufficient as compared to preset thresholds, a fall report will be generated. The wearable device optionally allows qualified professionals to adjust or customize the parameters to optimize the evaluation to the requirements of particular users or classes of users. The wearable device generally transmits data and alerts over a short distance to a console or over a long distance using a connection to a long-distance back haul communication system such as cell network or internet or both. The device thus transmit data and alerts to a call center or other designated location.
