Abstract: This underwater vehicle for cleaning submerged surfaces comprises a chassis and at least one brush for cleaning the surface to be cleaned, rotationally driven by a motor about an axis of rotation of this brush, the brush being able to move, with respect to a fixed part of the vehicle, in a translational movement along its axis of rotation in such a way that it can be pressed firmly against the surface to be cleaned under the effect of a vacuum created by the rotation of the brush, the brush comprising a rotation shaft inserted into a sleeve that rotates as one with the brush and rotationally driven by a drive system, the brush rotating as one with the sleeve because of fingers fixed to the sleeve and inserted into holes of the brush with the possibility of sliding parallel to the axis of rotation of the brush.

Abstract: The invention relates to a process for fitting connectors to optical elements to an integrated optical circuit (26) consisting of connecting at least one optical element to this circuit such that the outputs and/or inputs of each element are located approximately in the same plane (xoz) as the inputs and/or outputs of this integrated optical circuit (26), also located in the same plane (xoz). This process comprises the following steps:the circuit (26) is positioned on a template (35) with patterns that enable subsequent precise alignment of optical elements with inputs and/or outputs of the circuit (26);at least one block (29, 30) capable of holding the optical element(s), is positioned on the template facing the inputs and/or outputs of the circuit (26), and is fixed to the circuit (26);the template is removed, and the optical element(s) is (are) placed in each block (29, 30) the blocks then being aligned with the inputs and/or outputs of the circuit (26).
