Analysis of the vehicle occupant posture is a key problem in designing “smart airbag” systems. Vision based technology could enable the use of precise information about the occupant’s size, position, and posture in making airbag deployment decisions. In this paper, we present our experiments in estimation of the body posture of a sitting person using a motion capture system that performs analys...

Wind instrumentalists require a sophisticated functioning of their respiratory system to control their air stream, which provides the power for optimal musical performance. The air supply must be delivered into the instrument in a steady and controlled manner and with enough power by the action of the expiratory musculature to produce the desired level of sound at the correct pitch. It is sugge...
