Abstract: An optical emitter-receiver module includes a light source, a photodetector and a fiber. The light source emits an emitted beam. The fiber includes a core and an optical axis. The fiber has an outer surface, inclined at an angle of 45° with respect to the optical axis, having a mirror. The fiber has a notch, extending to the core of the fiber and having a face having a dichroic filter for reflecting a received beam. The light source is arranged relative to the mirror so that the emitted beam is reflected by the mirror and transmitted in the fiber. The photodetector and the face of the notch are positioned so that the received beam reflected by the dichroic filter is directed towards the photodetector.

Abstract: A system to communicate via modulated optical signals of the Li-Fi signal type to transmit data to and from a plurality of defined privileged spaces. The communicating system includes a plurality of first light sources, each first light source emitting, in the infrared, a first modulated optical signal. A plurality of optical fibers, each optical fiber guiding the first modulated optical signal from a single first light source in the direction of an optical interface. The optical interface transmitting the first modulated optical signal into a defined privileged space. Each optical fiber also transporting a second modulated optical signal from the associated defined privileged space in the direction of a device configured to acquire the second modulated optical signal.

Abstract: A method and assembly for locking/unlocking, formed of one of several a removable module (2) and a mount plate (3). The assembly includes a support wall (4) supporting each removable module (2). The removable module (2) being provided with two lugs (5) through which an aperture passes. The lugs (5) extending out of the removable (2) so that they can be inserted into opening (7) formed in the support wall (4). This assembly is equipped with a locking/unlocking system (100) having a lever (10) extending under the support wall (4) and provided with circular eccentric cams (11) arranged with offset axial symmetry in the form of an S about a central rotation axle (20) perpendicular to the support wall (4). The lever (10) being fixed in terms of rotation on this central axle (2) at equal distances from the two openings (7).

Abstract: A data management structure (1a) on board a transportation device, incorporating a cabin (100) provided with seats (110), includes a data resource block (210) incorporating audiovisual transmission system units (211 to 213), outward communication systems (100) and/or cabin systems, a standardised data distribution architecture (10a), and devices (E1 to E4) for operating said systems. In the structure (1a), the standardised architecture (10a) includes a concentration box (11) for the bidirectional transfer, on the one hand, of base signals with the resource block (210) and, on the other hand, optical signals with the devices (E1 to E4) of the cabin (100) on at least one optical fibre (2, 3; 2a, 2′a; 2b). This concentration box (11) houses units for processing (211 to 213) by signal switching, bidirectional conversion into optical signals, and optical signal management by wavelength allocation and distribution of downstream (F1) and upstream (F2) optical flows. This concentration box (11) is connected to the devices (E1 to E4) of said systems via intermediate boxes (30, 40) also housing processing units (111 to 113) according to the devices (E1 to E4) to which they are connected.
