Abstract: Disclosed is a system and a method for deploying and recovering an autonomous underwater craft by a ship-towed recovery vehicle. The craft is stored in the recovery vehicle's housing. The deployment is carried out in a first stage submerging the recovery vehicle with the craft stored therein, and a second stage releasing the craft. The ship includes a tilting launch ramp where the recovery vehicle is stored. The launch ramp takes at least a raised position with the recovery vehicle out of the water and an inclined position with the launch ramp rear end immersed. A translational device enables, in the launch ramp inclined position, the recovery vehicle to move along the launch ramp to be submerged and move from the ship while in tow during deployment and to be raised along the launch ramp during recovery. The system and the craft form an underwater exploration assembly.

Abstract: Disclosed is a method for estimating angular errors of coders for a looped system including a rotating actuator and an angle coder producing a position measurement signal, and including a calculation device controlling the actuator, the calculation device receiving a setpoint signal, as well as the measurement signal, for looping, the calculation device calculating in a corrector a control signal. In a test phase, a specific corrector Cωrj(q) is synthesised for constant rotation speed ωrj, the corrector having substantially zero gain at the frequency and harmonics, resulting in opening the loop at the frequencies, a matrix relation is established between position measurements and a function of parameters characterizing the coder errors and the torque ripples, the test phase repeats with different speeds, the matrix relations are concatenated producing an identifiable global matrix relation, the encoder error and torque ripple parameters are estimated by resolution of the global matrix relation.

Abstract: In a method for calculating, by an estimator, an instantaneous velocity vector {right arrow over (Vu)} of a rail vehicle, the estimator receives measurements from an inertial unit at a fixed point in the vehicle body and determines a mathematical model M of the dynamics of the vehicle moving on a track, the model being dependent on the bias of the inertial unit and installation parameters, a virtual sensor is determined based on the model M, the virtual sensor enabling calculation, from model parameters, two theoretical transverse velocities δvyc, and δvzc along axes yc and zc, respectively. An iterative estimator calculates {right arrow over (Vu)}, and includes the virtual sensor, the estimator being configured so the two theoretical transverse velocities are zero regardless of the rail configurations, the estimator enabling correction of the biases of the inertial unit and estimate installation parameters. Auxiliary velocity or distance travelled sensors are not used to calculate {right arrow over (Vu)}.

Abstract: An electrical connector includes an electrically conductive contact element (122) and a support (70). The contact element (122) is supported by an intermediate element (120) made of an elastically deformable material and connected to the support (70). An electrical connection assembly including a connector of the type is also described.

Abstract: Disclosed is a bathymetric system including a multi-beam emitting and receiving device attached to a carrier vehicle, configured, in a first recurrence, to measure the amplitude of a first plurality of beams reflected off the seabed, and a computer to determine three-dimensional spatial coordinates of a first scan swath. In a second recurrence, the device emits a second incident beam and measures the amplitude of a second plurality of beams reflected off the seabed, the computer determines the three-dimensional spatial coordinates of a second scan swath, so that at least one probe point of the first scan swath is redundant with a probe point of the second scan swath, and the computer calculates an altitude variation of the carrier vehicle using altitude variations of the at least one redundant probe point between the first recurrence and the second recurrence.

Abstract: Disclosed is a method for compensating for disturbing couples for a movement simulator, the simulator including, for each axis, a monovariable correcting unit that receives a signal giving the difference between the setpoint θrj and the measurement θj for the corresponding axis and producing the control signal Uj. The disruptive couples are Coriolis, centrifugal and gravitational couples and furthermore a compensating law calculates a formula (a) estimating the disruptive couples, calculated on the basis of an error εj(t) that is the control signal Uj filtered by a filter H(q−1), and the simulator is modelled with a dynamic model expressing the couples in an affine way with respect to a set of base parameters χ according to a matrix relationship of the type: formula (b), and a subset j of base parameters, the estimation of the couples being formula (c), and, online, the αj are calculated via an iterative equation.

Abstract: Disclosed is a broadband underwater acoustic transceiver device. The device can be used in particular for positioning, detection, range finding or underwater acoustic communication. The device coaxially combines, within a transceiver device, a Tonpilz transducer and a FFR transducer, the FFR being arranged in front of the transmission face/horn of the Tonpilz transducer. In such a configuration, the Tonpilz horn also acts as reflective tape for the FFR transducer, forming a common tape-horn element. Furthermore, an annular baffle surrounding the Tonpilz pillar creates a Helmholtz cavity for broadening the emission band towards the low frequencies.
