Abstract: A portable physical phase stratification and separator device that includes a “U”-shaped frame connected to a fluid sump having a tank with an inlet port is disclosed. The inlet port is connected to a calibrated sampling column having a graduated cylinder by a gate valve. Above the sampling column is a vacuum port that selectively applies a vacuum to draw a fluid sample from a reservoir. The vacuum can be supplied by an external vacuum pump or by an internal venturi pump. The drawn fluid sample is directed into the cylinder where it separates. A sample of the drawn fluid can be extracted for external analysis. Various valves and fittings route pressures and vacuums and fluid sample as required around and out the portable physical phase stratification and separator device.

Abstract: A system and method which may include on each locomotive a propulsion system and a braking system; a transceiver for communication between the locomotives; and sensors for sensing operational conditions on the locomotive. A processor receives the sensed operation conditions, communicates information including the sensed operational conditions to the other locomotive, determines a propulsion or braking value or command based on the sensed operational conditions, pre-selected criteria and the information received from the other locomotive, and outputs the propulsion or braking value or command.

Abstract: Systems and methods are disclosed for a computer implemented concierge system. The system includes receiving an itinerary having one or more guest interests indicated therein; receiving one or more vendor features or capabilities; filtering candidate trips by matching the guest interests with the vendor features; and displaying the filtered candidate trips for selection.

Abstract: A remote control locomotive simulator including a display and a first input device similar to a remote control locomotive controller to be operated by the operator to provide train signals. A computer drives the display to move a train relative to a track in response to the train signals. A remote control locomotive controller may be an actual remote control locomotive system or may be a virtual remote control locomotive controller where the input device is one or more of a keyboard, a mouse or a touch screen of the computer. Data associated with a simulator session of this device is recorded and made available for real-time or post-processing analysis including visual review of train management using the included computer generated graphics system.

Abstract: Setting a reference voltage for a bus agent including identifying a present configuration of a bus, the bus including conductive pathways connected to bus agents, the bus agents including computer hardware devices that use the bus for data communications among bus agents, the present configuration of the bus including the identity of the bus, the identities of one or more bus agents presently connected to the bus, and the order in which the bus agents presently are connected to the bus; identifying a reference voltage value for each bus agent; and applying a reference voltage to each bus agents in dependence upon the identified reference voltage value for each bus agent.

Abstract: A portable train simulator, including a microprocessor, a display and an input device for the microprocessor. A first program drives the display to depict indicia of a control stand and to respond to control inputs from the input device. A second program drives the display to depict a track to be traversed from a data file in response to the control inputs. A virtual control stand is one of the elements that allows the true portability of a train simulator. The system can display and switch between the present operating parameters of the train and/or a history of the operating parameters of the train, as selected by the input device. Thus, the system can switch from playback mode to simulation mode to provide a take-over of recorded conditions to allow an operator to explore alternate methods for managing the train.

Abstract: A tube heating assembly having a heating tube with proximate and distal end portions, a manifold insert disposed concentrically within the heating tube and likewise having proximate and distal end portions, and a pair of end caps removably secured to the proximate and distal end portions of the manifold insert and the heating tube respectively. The manifold insert includes a raised spiral thread on its surface. An electrical assembly such as a resistive path applied to the outer surface of the heating tube is used to heat the tube. The tube heating assembly may be embodied in a system and method for delivering an automotive fluid in a vehicle, wherein the tube heating assembly is installed as a heat exchanger in a fluid delivery path through which the fluid is pumped, preferably in pulses to enhance heating of the fluid.

Abstract: A test system for computerized single car test devices. The test system includes at least one car tester having a first connector for connecting a first port to a brake pipe of the car, valves for selectively interconnecting ports of the tester, at least one pressure sensor sensing pressure at one or more of the ports, a communication circuit and a local controller connected to the valves and sensor and programmed to perform a test of the brake system and connected to the communication circuit to transmit test results. A plurality of car testers may be in communion with and controlled by the central controller at the same time.

Abstract: A method of processing and displaying train performance including analyzing train data received from the train or train simulator real time or from a data storage and preparing display data of the results of the analysis. Computer graphic images are created from the display data; and the computer graphic images are provided for display. A display may be a drive with the display data and displayed portions of the display data may be selected to be created into computer graphic images. The computer graphic images may be transmitted over the internet or stored on a portable store and ultimately displayed on a video player. The computer graphic images may be viewed and edited or enhanced.
