Abstract: Controlling a level crossing includes one or more transceivers located in proximity of a level crossing area on a first side of a railway track; corresponding passive reflective targets located in proximity of the level crossing area on a second side of the railway track opposite to the first side where each transceiver is located and a control unit connected to each transceiver. Each target is arranged to receive RF signals coming from each transceiver and to send back corresponding reflected signals. Each transceiver is arranged to elaborate said reflected signals to calculate predetermined parameters values. Also, the control unit is arranged to acquire said parameters values from each transceiver and to elaborate them to detect the presence of a train in an area around the level crossing area and, in case of presence of said train, to send a warning message and/or close bars of the level crossing.
Abstract: System for determining train information relative to a train moving along a railway track having a pressure measuring device placed along the railway track and arranged to measure the speed of an airflow generated by the train when moving on the railway track, and to generate a speed signal; and a controller arranged to receive said speed signal and to determine train information relative to the train in function of said speed signal.
Abstract: This electrical switching apparatus has at least two power components each including first and second power transistors.

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: A method for commanding a railway level crossing protection system comprising: a) activating a railway signal preventing a train from driving beyond a level crossing; b) detecting an incoming train approaching the level crossing and measuring a speed of said incoming train; c) calculating a waiting time, as a function of the train's measured speed; d) waiting until expiration of the calculated waiting time and, once said waiting time expires, sending an order to commute the protection system into the protected state; and e) querying the state of the protection system and if said protection system is found to have commuted into the protected state, deactivating said railway signal, and maintaining said railway signal in the activated state otherwise.

Abstract: When an event prevents a train from moving along a route in a nominal direction, this method makes it possible to cause it to circulate in an opposite direction by: selecting (120) an origin zone and an output signal; drawing (130) a pseudo-route on the successive zones between the origin zone and the output signal; opening (140) the pseudo-route by associating a sub-route with each zone, corresponding to the reservation of said zone for said train; informing (150) the train that it must circulate in the opposite direction; determining (160) a movement authorization for the train from sub-routes that are open and a list of obstacles that is updated regularly; sending (180) the movement authorization to the train, the determination (160) and transmission (170) steps being iterated until the train crosses the output signal.
Abstract: The cooling device (12) according to the disclosure includes a case (20), designed to be arranged on a roof (16) of the vehicle, said case (20) comprising two side walls (22) and one upper wall (24) together delimiting a housing for each component. Each housing forms an air guiding duct in which the corresponding component is housed, said duct extending between at least one side air inlet opening (32) arranged in one of the side walls (22) and one upper air outlet opening (34), arranged in the upper wall (24).
