Abstract: A protective device includes an airbag assembly configured to extend at least partially around a waist or hips of an individual; a buckle attached to the airbag assembly, the buckle comprising a first buckle half, and a second buckle half, the first and second buckle halves being attachable to and detachable from one another; and an airbag actuator configured to actuate the airbag assembly. At least a portion of the airbag actuator is disposed in the first buckle half or the second buckle half.

Abstract: Systems including noise suppression devices for personal impact protection systems are provided. One such system includes an inflator having an inflator discharge port; a flexible permeable inner tube configured to receive gas from the inflator via the inflator discharge port; and a flexible outer tube surrounding the inner tube and configured to receive gas from the inner tube, the outer tube including one or more outer tube discharge ports. Another such system includes an inflator having an inflator discharge port; a flexible non-permeable tube configured to receive gas from the inflator via the inflator discharge port; and a permeable gas diffuser element disposed in or adjacent to the tube, the diffuser element being configured to receive gas from the inflator via the inner tube.

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.
