Abstract: The invention relates to a power switching device having at least one transistor of the SiC or GaN MOSFET type able to be traveled by a main current. The power switching device has at least one measuring module configured to indirectly measure the main current of the transistor from the electromagnetic field produced by the transistor and at least one protection circuit configured to detect a short-circuit based on the sign of the temporal drift of the main current.

Abstract: This method comprises the steps of generating an elementary signature for each electronic board from stored configuration data, transmission to each electronic board of the elementary signature, calculation by each electronic board of the signature variable as a function of the configuration variables, and checking by each electronic board of the validity of the stored configuration variables using the received elementary signature and the signature variable. The method comprises the implementation step for each electronic board for which the configuration variables are considered invalid, and comprises the retrieval of the configuration data specific to this board, and the modification of the configuration variables starting from the configuration data retrieved.

Abstract: A traffic management method, for managing traffic of a transportation network, comprising the steps of managing the traffic and the transportation network, according to a basis instruction timetable, automatically detecting and/or predicting a conflict in the traffic, generating a conflict solution in knowledge of the conflict, and managing the traffic and the transportation network with a modified instruction timetable based on the generated conflict solution. In the invention, the step of generating the conflict solution comprises the sub-steps of automatically splitting the transportation network into a local part, in which the conflict is involved, and a complementary part distinct from the local part, automatically generating a local solution relative only to the local part, automatically generating a complementary solution relative only to the complementary part, the complementary solution being generated in consideration of the local solution, and automatically combining the local and complementary solutions for obtaining the conflict solution.

Abstract: A method is for maintenance of a ground-level power supply for a transport vehicle. The device includes: a power supply rail, a detector of spatial coordinates of a vehicle; and a power supply shoe. The device and the shoe equip the same vehicle. The supply shoe includes a vibration sensor. The method includes measuring vibrations of the shoe and simultaneously detecting spatial coordinates of the vehicle during the movement of the vehicle along the rail, followed by comparing measured vibrations of the shoe with a threshold value, and determining spatial coordinates corresponding to vibrations above the threshold value.

Abstract: The invention concerns a method for determining the location of a railway vehicle comprising a first navigation module determining a regular resolution position of the railway vehicle with a first accuracy measurement and a second navigation module determining a high resolution position of the railway vehicle with a second accuracy measurement, using the received signals. The method comprises the steps of determining a first confidence area around the regular resolution position, based on the first accuracy measurement, of determining a second confidence area around the high precision position, based on the second accuracy measurement, and of assigning a weight of confidence to the knowing of the actual location of the railway vehicle, by analyzing the overlay of the first and the second confidence areas and the first and the second accuracy measurements.

Abstract: The present invention relates to a method for determining the location of a train on a track or of a broken rail of a track, the track including a first section having a first end and a second end, the method including: injecting a current into the track at one end of the first end and second end; detecting the amplitude of the injected current at the same end at which the current was injected; and determining, based on the detected amplitude, the location of the train on the track or of the broken rail of the track.

Abstract: Controlling a level crossing of a railway track by providing a train having an onboard processor communicating with a wayside processor associated to a level crossing, said train having a forward end and a rear end; moving the train forward along the railway track lowering down gates of the level crossing when train is at a predetermined distance upon detection of the train approaching the level crossing; when the forward end passes over a first reference point defining the beginning of an island area of the level crossing, sending a first message from the onboard safety processor towards the wayside processor informing that the train is approaching the level crossing; maintaining down gates; when the rear end passes over a second reference point defining the end of the island area, sending a second message from the onboard safety processor to the wayside processor informing that the train has left the level crossing; and lifting the gates.

Abstract: A method controls the height of a floor of a car of a vehicle relative to a platform. The car includes a body provided with a distance sensor, at least one bogie and at least one secondary suspension between the bogie and the body. The method includes measuring the distance between the distance sensor and the platform via the distance sensor, calculating the difference between the height of the platform and the height of the floor from the measured distance, and adjusting the height of the secondary suspension based on the difference.
