Abstract: A system and method provide the capability to dynamically measure the diameter of a train wheel. An onboard sensor signals detection and loss of detection of a proximity plate having a predetermined length and placed along a direction of travel of the train. A signal generator generates a signal indicating the number of revolutions of the wheel. Based on the sensor signals indicating detection and loss of detection of the proximity plate, the length of the proximity plate, and the corresponding number of wheel revolutions, a controller automatically calculates the wheel diameter.

Abstract: Disclosed is a method of controlling a load in a railway signaling system, the method comprising providing a first autonomous controller connectable to the load and a second autonomous controller which is redundant with the first controller such that there is no single point of failure; operating the first and second controllers in one of two modes. There is an on-line mode wherein both controllers provide power to the load to control the load such that current through the load is shared between the first and second controllers. There is an off-line mode wherein a single controller does not provide power to the load and the other controller continues to operate on-line to control the load, whereby control of the load is uninterrupted.

Abstract: A signal aspect enforcement method for a rail vehicle includes determining if vehicle position is unknown. The system determines if rail vehicle speed is less than a line-of-sight threshold speed. The system determines the grade of the rail. A worst-case braking distance of rail vehicle is calculated. The signal aspect is determined using a camera system and a beacon system. The system determines if the signal aspect determined by camera system is same as signal aspect determined by beacon system and, if so, determines the route of rail vehicle and speed limit of rail vehicle.

Abstract: A method and a system are disclosed for detecting, isolating and estimating a degradation of a corresponding component of an actuator controlled by an actuator command signal, the method comprising obtaining a control signal of the actuator; obtaining a signal indicative of a displacement of the actuator; computing an envelope of admissible values for the displacement of the actuator; determining if the displacement of the actuator is outside the computed envelope and in the case where the displacement of the actuator is outside the computed enveloped computing an estimation of each parameter and state of the actuator; identifying at least one corresponding parameter responsible for causing the actuator displacement to be outside the computer envelope and providing an indication of the at least one corresponding parameter.

Abstract: A method of improving robustness of a deep neural network (DNN), the method including: applying a coverage metric to a trained DNN based on a test set to determine test set adequacy; monitoring a performance of the trained DNN; based on the performance, applying new data to the trained DNN; applying a novelty metric to an output of the trained DNN based on the applied new data to identify a subset of the applied new data in response to determining whether new features are generated; and identifying the subset of the applied new data.

Abstract: A vehicle-position monitoring system includes liquid-capacitive inclinometer sensor, configured to provide a measurement of grade (θgrade) of a surface over which a vehicle travels, and an accelerometer to measure acceleration of the vehicle along a principal axis (ax) of the vehicle along the surface. Direct measurement of the grade (θgrade) provides a position-tracking system with accurate information to extract acceleration due to motoring and braking (aMB) from acceleration experienced along the principal axis and track vehicle position without regard to wheel diameter calibration.

Abstract: The vehicle odometry and motion direction system and method is described. The vehicle odometry and motion direction system and method determines if the first ground speed data is acceptable. Ground speed data is calculated for all targets within a radar's field of view and targets ground speed data is processed to determine second ground speed data. The vehicle odometry and motion direction system and method determines trusted ground speed data using first ground speed data and second ground speed data and adjusts the trusted ground speed data due to errors in radar Doppler speed data.

Abstract: Systems and methods of calibrating an Inertial Measurement Unit (IMU) on a vehicle are disclosed. In some embodiments, a first tilt angle of the IMU is measured with the IMU while the vehicle is stationary. A second tilt angle of the IMU is measured with an inclinometer or tilt sensor while the vehicle is stationary. The orientation of the IMU is corrected based on the first tilt angle and the second tilt angle.
