Method and apparatus for body impact protection
First Claim
1. A system comprising:
- a first orientation sensor configured to detect three-dimensional torso motion over time of a torso of a rider of a vehicle or animal, the first orientation sensor comprising;
a multiaxial accelerometer configured to detect acceleration in at least three mutually orthogonal directions, anda gyroscope;
a second orientation sensor configured to detect three-dimensional motion of a vehicle frame of the vehicle or an animal torso of the animal; and
a controller configured to receive data from the first orientation sensor and the second orientation sensor, the controller being programmed to process the data to;
compare the three-dimensional torso motion detected by the first orientation sensor to the three-dimensional motion detected by the second orientation sensor over a period of time,identify a degree of variation over time between the three-dimensional torso motion detected by the first orientation sensor and the three-dimensional motion detected by the second orientation sensor, anddetermine whether the degree of variation over time between the three-dimensional torso motion detected by the first orientation sensor and the three-dimensional motion detected by the second orientation sensor is within a programmed limit of the degree of variation; and
a body impact protection device comprising an inflator and an inflatable airbag;
wherein, when the controller determines that the degree of variation over time between the three-dimensional torso motion detected by the first orientation sensor and the three-dimensional motion detected by the second orientation sensor is outside the programmed limit of the degree of variation, the controller sends a signal to the body impact protection device to cause the actuator to inflate the inflatable airbag.

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.
