Abstract: A system for the recovery of a surface marine craft by a carrier ship includes a lifting device with which the carrier ship is intended to be equipped and which includes a lifting unit of the davit type, equipped with a lifting cable including, at one end, a connection interface, a pole bearing a guide cable, an anchor connected to one end of the guide cable, the connection interface for the lifting cable being coupled removably to the anchor, and a hauling cable. The system also includes a receiving device with which the marine craft is intended to be equipped, the receiving device including a forward module.
Abstract: A device (10) for detecting a signal of interest in order to locate an underwater source of the signal. The device includes a receiver (13) configured to detect the signal of interest, an actuator (14) configured to allow at least a portion of the detection device (10) to move towards a zone indicating a result of detection of the signal of interest in response to the receiver being operated, and an emitter (15) configured to indicate the result of detection of the signal of interest.
Abstract: Sonar intended to be carried by a naval vehicle including at least one element for transmitting an acoustic signal, at least one element for receiving the acoustic signal transmitted and reflected on the sea bed and at least two phase centers (PC1, PC2) that are disposed along a first and a second axis (v1, v2), respectively, forming an interferometric antenna. The sonar includes elements for determining the speed of movement of the vehicle as a function of the computed value of the relative trim angle (?) formed between a straight line (d1) that is perpendicular to the axes (v1, v2) of the phase centers and a straight line (d2) that is perpendicular to the sea bed (F) and of the value determined for the angle of sight.
Abstract: Marine or underwater vehicle designed to be secured to a recovery cable includes contactless elements (6) for detecting the recovery cable (2), the element being capable of guiding the vehicle (1) towards the cable (2) and elements (7) situated at one end (3b) of the vehicle (1) for coupling the cable (2).
Abstract: A device for monitoring and collecting information (10) from an area with potential risk of irradiation, including at least one storage box (12) intended to be positioned permanently in a nuclear infrastructure (2) and including a unit for communication with a control station (14) intended to be positioned outside (8) the nuclear infrastructure (2), characterized in that the storage box (12) is intrinsically protected from any external stresses, and includes a televisual inspection unit and a unit for measuring environmental parameters that can be deployed from inside the nuclear infrastructure (2).
