Abstract: An electrically insulating mechanical joint checker for mechanical joints connecting rails of following track segments of a railway line, each track segment forming part of a track circuit. The track segment includes electric signal transmitting units and receiving units for transmitting and receiving train presence detection signals within the track segment and/or relating communication signals between the train and the track segment. The train presence detection signals and communication signals include a further joint detection signal, generated and transmitted by the transmitting units and received by the receiving units belonging to the same track segment, the joint detection signal relating to the track segment being different at least in respect to the one relating to the adjacent track segments. A method to detect a failure or breakage of a mechanical joint inside a track segment is also disclosed.

Abstract: This motor includes a frame defining an inner space (VI) in which a rotor, a stator and a fan are housed, the frame comprising an a first opening placing the inner space (VI) of the frame in fluid communication with the outside of the frame, a second opening placing the inner space (VI) of the frame in fluid communication with the outside of the frame along a radial axis (R) substantially perpendicular to a rotation axis (X) of the rotor. The fan being arranged near the second opening and being configured to create a flow (F) of a gaseous fluid, a first acoustic attenuation device is housed in the second opening so as to partially close the second opening.

Abstract: This test method for validating a specification of a graphical interface consists of developing a scenario file corresponding to the validation test to be performed. The scenario file includes a plurality of instructions, in a natural programming language, each instruction including a function, parameters and an expected state of the graphical interface following the application of the function. The test is automatically performed by interpreting the scenario file so as to generate commands intended for an engine capable of interacting with the graphical interface and monitoring the evolution of its current state, and then analyzing a result file associating each instruction of the scenario file with a result corresponding to the comparison of the current state of the graphical interface following the application of the corresponding command with the expected state.

Abstract: A method for applying a plurality of vehicles each including an onboard server and at least two apparatuses, an onboard server and each of the apparatuses storing initial data, each onboard server being connected to the apparatuses mounted in the same vehicle with a local network. The method includes the steps of transferring modified data, through an extended radiofrequency communication network, from a server on the ground towards the onboard servers, when the modified data have been stored in memory in each onboard server, emitting via the extended network, an updating command, and transmitting modified data to at least one apparatus through the corresponding local network, the modified data replacing, in said apparatus, the initial data.
