Vehicle Communication System
A communication system uses a vehicle system controller to control operation of a vehicle system. An electronic air brake (EAB) controller and an electronically controlled pneumatic (ECP) brake controller control operation of a brake of the vehicle system. One or more network connections communicate data packets between the vehicle system controller and the brake controllers to allow the vehicle system controller to control the brake of the vehicle system using data packets communicated between or among two or more of the vehicle system controller, the EAB controller, or the ECP controller to allow the vehicle system controller to control the brake of the vehicle system.

WINDSCREEN FOR HOUSING A SANDING SYSTEM, RAILWAY VEHICLE WITH SANDING SYSTEM, AND METHOD FOR INSTALLING A SANDING SYSTEM IN A RAILWAY VEHICLE
A windscreen for housing a sanding system, a railway vehicle with a sanding system, and a method for installing a sanding system in a railway vehicle are described. The windscreen includes a first shell element and a second shell element, the first shell element being detachably connected to the second shell element, wherein the first and second shell elements, when assembled, form an interior space. A container is in communication with a sanding system for housing material used when the sanding system is in operation, wherein the container is configured to be positioned in the interior space formed by the first and second shell elements of the windscreen.
Compressor Piston Shape to Reduce Clearance Volume
A piston assembly for reducing clearance volume in a reciprocating compressor for compensating for piston tilt and improving the volumetric efficiency of the compressor includes a piston located within a piston cylinder, the piston having a first end and a second end, a wrist pin associated with the first end of the piston, and a cylinder head/valve assembly associated with the second end of the piston, wherein at least a portion of the second end of the piston includes an angled portion. The piston having the angled portion can be used with oil free cylinders and trunk type pistons. The piston can also be used in a multiple stage, multiple cylinder compressor including a series of piston assemblies. A method of increasing the volumetric efficiency of a reciprocating compressor can also be achieved using the piston having an angled portion.
SYSTEMS AND RESISTORS FOR DYNAMIC BRAKING
A resistor includes an elongated cylindrical body having nodes and elongated members. The elongated members interconnect the nodes to form openings between the nodes and the elongated members for the flow therethrough of a cooling fluid. The body is configured to receive electric current from a powered system and to conduct and provide electric resistance to the electric current to dissipate at least part of the electric current as heat from the body. The body may be coupled with at least one other resistor of the powered system in one or more of a parallel or series arrangement in an electric circuit.
Rail vehicle braking device
A rail vehicle braking device has at least one first electrodynamic brake with a drive unit that includes at least one drive motor and a power supply unit for supplying the drive motor in a traction mode of the drive unit. A brake control unit controls, in a first brake mode, the respective power supply unit for providing a braking effect. In order to optimize the system with a fall-back measure in case of a braking effect loss in respect of the cause thereof, there is provided at least one sensor unit, which detects a braking effect parameter for the first braking mode of the brake. A monitoring device is assigned to the first brake. It is independent of the brake control unit and considers, in a first monitoring mode, the braking effect parameter for the introduction of a fall-back measure concerning the brake.

Convoy operations for electrified military vehicles
An electrified military vehicle system includes a first military vehicle and the second military vehicle. The first military vehicle includes a prime mover configured to drive the first military vehicle and a first mechanical coupling interface positioned at a rear end of the first military vehicle. The second military vehicle includes an axle, a second mechanical coupling interface positioned at a front end of the second military vehicle where the second mechanical coupling interface is configured to engage with the first mechanical coupling interface to selectively couple the second military vehicle to the first military vehicle, an energy storage system, and a generator coupled to the axle and electrically coupled to the energy storage system. The generator is configured to generate electric power while the axle rotates as the second military vehicle is towed by the first military vehicle to charge the energy storage system.
Anti-collision method and apparatus for trains in cooperative formation
The embodiments of the present application disclose an anti-collision method and apparatus for trains in a cooperative formation. The anti-collision method includes: determining whether it is necessary to control the current train to brake; determining whether a real-time distance between the current train and a previous adjacent train in the same formation as the current train is greater than a preset minimum safety distance; controlling, under a condition that the real-time distance is less than the preset minimum safety distance, the current train to perform electromagnetic braking; and calculating, under a condition that the real-time distance is greater than the preset minimum safety distance, a real-time safety distance between the current train and the previous adjacent train, and controlling, under a condition that the real-time distance is less than the real-time safety distance, the current train to brake.
