Abstract:
1. A device, comprising: at least one kinematic sensor that measures kinematic information associated with a wearer of the device, the kinematic information including threshold kinematic information and fall event kinematic information; and a controller that analyzes the threshold kinematic information to determine whether a threshold indicative of a postural disturbance is satisfied, and classifies the postural disturbance as a fall event or a recovery event based on the fall event kinematic information, wherein the controller further determines a fall direction based on the threshold kinematic information, wherein the fall event kinematic information includes at least one of an acceleration in the fall direction measured at a first predetermined time after onset of the postural disturbance and a vertical displacement measured at a second predetermined time after onset of the postural disturbance, and a vertical displacement measured at a third predetermined time after onset of the postural disturbance.
