摘要： A measurement device intended to be immersed in water, includes a set of arms and a reference axis, the measurement device being able to be in a deployed configuration, the measurement device comprising a set of measurement units borne by arms of the set of arms and each comprising an acoustic-waves sensor, the set of measurement units being configured and arranged in such a way as to generate a torque on the measurement device about the reference axis upon a vertical translational movement of the measurement device in the deployed configuration, the measurement device comprising compensation means configured and arranged in such a way as to generate another torque on the measurement device about the reference axis during the vertical translational movement, the other torque being directed in the opposite direction to the torque and having an intensity less than twice that of the torque.

摘要： An underwater device intended to be deployed in the water, the device includes a set of arms articulated to a support body having a reference axis r, the arms being able to be kept in a furled configuration and able to deploy into a deployed configuration wherein the arms extend about the reference axis r, the arms deploying by distal ends of the arms moving away from the axis r, a set of at least one bending spring stressed elastically in bending when the arms are kept in a furled configuration and able to relax when the arms are released from the furled configuration, the set of at least one bending spring being configured and arranged in such a way as to exert, on at least one of the arms, when the arms are released from the furled configuration, a thrust that instigates the deploying of the arms.

摘要： A buoy includes a surface unit comprising a sealed tank comprising an inflatable bag, a tubular wall of axis z and a bottom, the tubular wall and the bottom delimiting a volume referred to as the inner volume, the surface unit comprising at least one cartridge enclosing a compressed gas that can be released in such a way as to inflate the inflatable bag such that it functions as a float in an operational configuration of the buoy, and the sealed tank comprises a projecting container protruding from the bottom and extending out from the inner volume, from the bottom.
