Abstract
A motion analysis system includes: at least one orientation sensor configured to detect three-dimensional torso motion over time, the at least one orientation sensor including: a multiaxial accelerometer configured to detect acceleration in at least three orthogonal directions, and a gyroscope; and a controller configured to receive data from the at least one orientation sensor, the controller programmed to process the data to: determine at least one of a state and a transition of the torso; identify normal parameters for the determined at least one of the state and transition; and determine whether motion of the torso is outside the normal parameters. The controller is configured to identify, in real-time, the occurrence of a fall in progress of an individual from at least one of a standing state, a standing-to-seated transition, and a seated-to-standing transition.

32. A motion analysis system comprising:
-
at least one first orientation sensor configured to detect three-dimensional torso motion over time, the at least one orientation sensor comprising; a multiaxial accelerometer configured to detect acceleration in at least three orthogonal directions, and a gyroscope; at least one second orientation sensor configured to detect three-dimensional motion of a vehicle frame or an animal torso; and a controller configured to receive data from the at least one first orientation sensor and the at least one second orientation sensor, the controller being programmed to process the data to; compare the three-dimensional torso motion detected by the at least one first orientation sensor to the three-dimensional motion detected by the at least one second orientation sensor over a period of time, identify the degree of variation over time between the three-dimensional torso motion detected by the at least one first orientation sensor and the three-dimensional motion detected by the at least one second orientation sensor, and determine whether the degree of variation over time between the three-dimensional torso motion detected by the at least one first orientation sensor and the three-dimensional motion detected by the at least one second orientation sensor is within an allowable degree of variation. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
