Abstract
The invention relates to a device for the detection of an obstacle (43) in relation to a controlled-movement panel (3), including: deformable tubular means or a flexible tube (31) for the propagation of low-frequency dynamic pressure waves; means for transmitting (40a) and receiving (40b) the low-frequency dynamic pressure waves; and means for processing (9) said dynamic pressure waves, which, upon detection of an obstacle, are designed to allow the panel (3) to be moved in relation to the obstacle (43), the panel being stopped, lowered or re-opened.
