Abstract: A method for evaluating the angular velocity of a railway vehicle circulating on a track, the vehicle including an inertial unit including at least one angular velocity sensor, the method including measuring an instantaneous angular velocity provided by the sensor, determining the bias of the angular velocity measured around at least one axis, the velocity bias being taken as equal to the value of the angular velocity measured around this axis when the measured angular velocity is substantially constant for a predetermined period, and calculating the evaluated angular velocity, by subtracting from the measured angular velocity, the previously determined velocity bias.

Abstract: A device includes an air curtain generator including air curtain diffusor able to diffuse at least one air curtain along a plane, in at least first and second different diffusion directions. The air curtain generating device includes a control unit able to control the diffusion of the at least one air curtain in one and/or the other of the first and second diffusion directions.

Abstract: The lighting management device comprises a variable lighting system which includes: at least one exterior light sensor, that is capable of measuring the characteristics of the exterior light outside the vehicle, and at least one interior image capture device, that is capable of capturing images within the interior of the compartment; and a control unit for controlling the lighting system, configured so as to adjust the lighting in the compartment based on the brightness of the exterior light measured outside the vehicle and the images captured within the interior of the compartment.

Abstract: A specific module of a communications network comprises (i) first and second telephone interface mechanisms respectively connected to telephone channels, (ii) interconnection mechanisms between these first and second interfaces, and (iii) a processing mechanism. In response to a request for a telephone call from a telephone set calling a call (dialing) number assigned to a portable handset, the call request being received at one of the first interfaces, an attempt is made to establish, in addition to the first telephone connection from the calling set to said first telephone interface, a second telephone connection from the portable handset to one of the second telephone interfaces in accordance with predetermined conditions, and the interconnection of the first and second interfaces concerned is obtained.

Abstract: In a communications network between fixed stations and fixed terminals, the said fixed stations being linked to the telephony channels while the fixed terminals include an antenna for mutual interaction over distance with independent stations, connection means to the telephony channels of the network are provided, and there is established a telephony relationship between an independent station and another station linked to the telephony channels of the network, by an intermediary of a primary link between the independent station and the connection means, via antennas of a primary fixed terminal. A secondary fixed terminal is chosen on the basis of predetermined selection criteria, and a secondary link is established between the independent station (SA) and the connection means, via an antenna of the secondary fixed terminal.
