Abstract: Embodiments of the present disclosure include a walker equipped with one or more sensors, an onboard controller, powered wheels and associated motor controllers. The walker can sense its distance from the user and activate the powered wheels when commanded by the controller. The controller can execute programming including an automatic feedback control algorithm that regulates the distance between the walker frame and the user. In this manner, the walker automatically follows the user, keeping the user from having to expend energy to pull the walker along. The walker can then be utilized by the user solely for balance and support.

Abstract: A vehicle system comprises an interface assembly and a controller both on board a first rail vehicle. The interface assembly comprises one or more mechanical couplers, fuel couplers, fluid couplers, and electrical connectors, to detachably couple the first rail vehicle to a separate, adjacent fuel tender vehicle, for the transfer of one or more of fuel (e.g., compressed natural gas) from the fuel tender vehicle to the first rail vehicle, heated fluid from the first rail vehicle to the fuel tender vehicle (e.g., for regasification of liquid natural gas stored in the fuel tender vehicle to the compressed natural gas), or electrical power and/or control signals between the first rail vehicle and the fuel tender vehicle. The controller is configured to at least partially control operations of the first rail vehicle in relation to interfacing with the fuel tender vehicle for fuel transfer, heated fluid transfer, etc.

Abstract: A system, method and device for communicating information from a wayside device to a vehicle are provided. In one embodiment, the device comprises.

Abstract: A communication method includes the steps of, at a first system, communicating with a second system for the establishment of a mutual clock and, at the first system, performing a first set of operations based on the mutual clock and performing a different, second set of operations based on a first clock of the first system, wherein the first clock is different from the mutual clock.

Abstract: A system for controlling a consist of at least first and second rail vehicles, the first and second vehicles being configured for receiving control signals via a communication link. The system includes a first control unit electrically coupled to the first rail vehicle, the first control unit being configured to receive signals representing a level of a non-propulsion consumable resource on-board the first rail vehicle and a second control unit electrically coupled to the second rail vehicle, the second control unit being configured to receive signals representing a level of a non-propulsion consumable resource on-board the second rail vehicle. The level of the non-propulsion consumable resource on-board the first rail vehicle and the level of the non-propulsion consumable resource on-board the second rail vehicle are shared across the communication link.

Abstract: A display system for displaying information to a vehicle operator comprises one or more projectors positioned in an operator cab of a vehicle. The projector is configured to project a heads up display of a plurality of data sets on a windscreen of the vehicle. Projected data sets are positioned in the heads up display and/or moved within the heads up display based on assessed relative priority levels of the data sets. Thus, for example, a data set with a higher assessed relative priority level may be positioned in a location of greater operator viewing prominence. If the priority level drops, the data set may be moved to a position of lower operator prominence. Respective heads up displays may be projected on more than two separate windscreens of the vehicle, either simultaneously or at alternate times, and possibly depending on an operational mode of the vehicle.
