iFall - a new embedded system for the detection of unexpected falls

This paper describes a new embedded system, called iFall, for the detection of unexpected falls for elderly people. In combination with a new sensors system and the monitoring of its own rotation, iFall is able to detect a fall in its very beginning. It is thus able to initiate some emergency actions, such as inflating a tiny airbag, in order to alleviate a fall's consequences, primarily potential injuries. In that respect, iFall is unique. It's physical properties, such as size, weight, and energy resources, make it almost invisible, so that it can be worn at any time at any occasion by any person
