Abstract: Example embodiments relate to implementing electromechanical drive systems and auxiliary braking systems on freight cars and other railway vehicles. Such motive systems can include electric motors and power sources that can be installed on new or existing non-locomotive railway vehicles to supplement and/or replace energy typically generated by one or more locomotives in the trainset. Some motive systems further include regenerative braking systems that can supplement existing braking systems and enable energy to be captured and stored locally at batteries onboard the railway vehicle for subsequent use by the drivetrain. A computing system may use sensor data from onboard sensors, route data, weather data, and/or other sources of information to determine and execute control strategies that leverage the drive system and auxiliary braking in ways that reduces the power required by locomotives and/or the stress impacting couplers between railway vehicles within the train.

Abstract: A helical pile including a heat exchanger is described. The pile is formed from a lead section and one or more extension sections. The interior of the lead and extension sections are hollow and form a heat exchanger cavity. At the lower end of the lead section is a helical blade. Rotation of the lead section causes the helical blade to screw into the ground, thus pulling the lead section downward. Extension sections are added to the lead section and the pile is rotated until it is installed to a desired depth. The pile includes an inflow tube extending a predetermined distance into the heat exchanger cavity and an outflow port connected with the heat exchanger cavity. In operation, a heat carrying fluid is pumped into the inflow tube from a heat source or sink, for example, a heat pump for a building heating and cooling system. The fluid exits the tube at a point near the bottom of the heat exchanger cavity. The fluid flows upward through the heat exchange cavity and exchanges heat with the surrounding soil.

Abstract: Systems and methods for using stratigraphic heat maps to steer a well being drilled. Data from one or more offset wells can be provided to a computer system and used with data from a well being drilled to generate one or more stratigraphic heat maps during the drilling of the subject well.
