Abstract (en)
[origin: WO2007003719A1] The invention concerns a device for detecting a body falling in a volume of water (20) of a pool comprising a probe (1) adapted to transmit aquatic waves propagated in the pool (20) and an electronic unit (4) adapted to receive and interpret electric signals representing pressure variations caused by the aquatic waves received by the probe. The probe (1) has a free end (11) immersed in the pool (20) and a substantially vertical axis (12). The device further comprises an immersed rigid obstacle (3) extending between the immersed end of the probe and the surface of the volume of water of the pool in a plane substantially perpendicular to the axis of the immersed probe. The rigid obstacle (3) enables disturbances caused by the surface waves to be eliminated from the measurements of pressure variations caused by the aquatic waves in the probe (1).
