Vigi’Fall detects falls using multidimensional contextual analysis.  It is a miniature accelerometric box attached to the chest with an adhesive patch.  Motion sensors are placed in several rooms of the home and doubt-removal software is placed in a home box.  The system is linked to a remote call center which contacts rescue teams in the event of a fall.  The next phase of the product will incorporate heartbeat monitoring.
