摘要： A sensor system includes one or more sensors 116 that sense vibrations of a vehicle 104 and one or more processors 106; 118 that can determine a speed of the vehicle 104 and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle 104) indicate damage to a propulsion system 110 of the vehicle 104. The one or more processors 106; 118 optionally may determine a hunting frequency of a wheel 112 and axle set and/or a lateral acceleration of the wheel 112 and axle set from the vibrations. The one or more processors 106; 118 can determine a conicity of a wheel 112 in the wheel 112 and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

摘要： A system is provided for use with a wheeled vehicle. The system includes a media reservoir capable of holding a tractive material that includes particulates; a nozzle in fluid communication with the media reservoir; and a media valve in fluid communication with the media reservoir and the nozzle. The media valve is controllable between a first state in which the tractive material flows through the media valve and to the nozzle, and a second state in which the tractive material is prevented from flowing to the nozzle. In the first state, the nozzle receives the tractive material from the media reservoir and directs the tractive material to a contact surface such that the tractive material impacts the contact surface that is spaced from a wheel/surface interface. The system can modify the adhesion or the traction capability of the contact surface with regard to a subsequently contacting wheel.

摘要： Methods and systems detect short circuits in an electrical system (104), such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements (202) of an electrical system (104). The current is supplied to the electrical system (104) from a power source (102) as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements (202) is determined. The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source (102). A short circuit event is identified based at least in part on the resistance change signal.
