Abstract: A measurement process, intended for measuring at least one wheel of a train, including an acquisition step, during which a plurality of profiles of at least a part of the wheel are acquired by plurality of optical sensors, as the train moves in front of the optical sensors, a mapping step, during which, for each optical sensor, the profiles acquired by the optical sensor are joined by a control module, to obtain a map of the part of the wheel further transformed into a cloud of points, a rejoining step, during which the clouds of points obtained from the optical sensors are joined to form a three-dimensional image of the wheel, and an analysis step, during which a plurality of reference points and reference distances are measured on the three-dimensional image.

Abstract: Method for detecting rail switches degradation and failures, the method having the steps of applying a Discrete Wavelet Transform to stored measurement data relative to a switch move to be analysed and obtaining a feature vector associated with said switch move and including Discrete Wavelet Transform coefficients delivered by the applied Discrete Wavelet Transform; comparing the obtained feature vector with feature vectors associated with rail switch moves previously obtained and associating each to a respective health class among several given health classes; and determining a health class for the said switch move to be analyzed by selecting one of the health classes associated with the previously obtained feature vectors based upon the comparison step.

Abstract: Disclosed is a method for determining the relationship between a track-circuit current signal and a railway vehicle location, including: sending, by a track circuit, current signal across a railway track block; measuring the current signal for different railway vehicles running successively on the railway track block; aligning the measured current signals and calculating a reference curve as the average value of all the aligned curves by using a Dynamic Time Warping algorithm, this reference curve representing the relationship between the track-circuit current signal and the railway vehicle location on the railway track block.

Abstract: A method for controlling the deformation of a wheel includes obtaining, for multiple predefined angular positions on the wheel, a parameter characterizing an angular velocity of the wheel when the wheel is in contact with the running surface at each predefined angular position while the wheel is rolling on a running surface, and calculating a radius value of the wheel for each predefined angular position using the parameter characterizing the angular velocity obtained for that angular position.

Abstract: Method and system for communicating data between a transmitter and a receiver via a physical transmission medium interposed there between, wherein the transmitter outputs over the transmission medium towards the receiver, a predefined precursor signal followed by a target signal carrying data packet. Based on the precursor signal received at the receiver, estimated values of actual electrical parameters of the physical transmission medium are computed via a predetermined model of the physical transmission medium, wherein the computed estimated values of the electrical parameters are indicative of a distortion caused by the physical transmission medium on the predefined precursor signal outputted by the transmitter. The data packets originally outputted by the transmitter are estimated based on the computed estimated values of the actual electrical parameters and on the target signal received at the receiver.

Abstract: This thermal conduction device intended to be installed between a first heat source part and a second heat dissipation part, comprises a male element comprising a protruding part relative to a base and a female element comprising an inner wall defining a housing for receiving the protruding part. The male element is configured to exert a radial force against the inner wall when the thermal conduction device is installed between the first heat source part and the second heat dissipation part so as to improve the thermal conduction between the male element and the female element.
