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 marine surface drone including: - an on-board multi-beam sonar; - a system for controlling the sonar, configured to command, for a given position of the drone, a plurality of consecutive transmissions of acoustic waves, the control system controlling the sonar transmitters so as to vary the characteristics of the transmitted acoustic waves, from one of the transmissions to the next, and - an acquisition unit configured to determine, from echo signals acquired in response to the plurality of transmissions, a three-dimensional image representing the content of a given observation volume. The invention also relates to a method for characterising an underwear environment, implemented by such a drone.

Abstract: Disclosed is an echosounder configured to: a) drive the transducers of its emitting antenna to emit first and second acoustic waves having first and second frequencies, these waves being superposed over one another along an axis of superposition that is directed toward a point of the bottom of the subaquatic environment, and b) acquire an echo signal, the frequency of which is equal to the difference between the first and the second frequencies, the echosounder being configured to perform steps a) and b) a plurality of times while varying the orientation of the axis of superposition, and to determine, on the basis of the acquired echo signals, an image representative of the content of the sub-bottom of the subaquatic environment beneath each of the points. Also disclosed is an associated method for characterizing a portion of the sub-bottom of a subaquatic environment.

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.
