Abstract:
1. A device for detecting an obstacle in relation to a movement-controlled panel and/or for controlling the movement of the panel in relation to the obstacle, characterized in that it comprises: deformable tubular means or a flexible tube for the propagation of dynamic pressure waves of low frequency, less than 500 Hz, these deformable tubular means or flexible tube also being able to create and propagate a dynamic pressure pulsed wave of very low frequency, less than 100 Hz, emitted in response to the docking impact of the moving panel on the obstacle, means for emitting and receiving said low-frequency dynamic pressure waves, and receiving said very low frequency dynamic pressure pulsed wave, these emitting and receiving means being adapted notably in dynamic pressure impedance to said deformable tubular means or flexible tube, means of processing said dynamic pressure waves and dynamic pressure pulsed wave adapted to: determining the detection of the obstacle by the moving panel, docking impact or deformation of said deformable tubular means or flexible tube, and
