Method and apparatus for body impact protection
First Claim
1. A motion analysis system comprising:
- at least one 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, anda 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 parameterswherein 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.

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.
