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.
