Abstract: The present invention relates to a system for monitoring the state of vigilance of an operator including: a camera furnished with a sensor responsive in the near infrared, a circuit for real-time processing of the signals delivered by the camera, so as to determine characteristic points for each of the images. By analysing the characteristic points, the information relates to a part at least of the indicators including: the inclination of the head in three orthogonal directions, the position of the pupil, the opening of the eye, and/or the configuration of the mouth. Furthermore, a computer controlled by a program determines the state of vigilance as a function of the indicators and of their temporal evolution.

Abstract: The system for rapid mounting and removal of a carrier on and from a support frame comprises a handle which is accessible at the front of the carrier and the ends of which are joined to two side arms pivotally mounted on two shafts. The handle is locked in the top position by means of a blade-spring device. Two studs come into position within notched portions of the arms. Each stud is attached to a spring, the other end of which is attached to the support frame. The springs are stretched in order to bring the studs into an initial stop position. After mounting of the carrier, higher tension is exerted and has the effect of locking the carrier position.
