Abstract: During operation of a machine, an understanding of terrain features is critical. Accordingly, disclosed embodiments augment a video stream, captured by a camera mounted on the machine, with terrain information. In particular, an overlay is generated on at least one image frame. The overlay, which may comprise one or more semi-transparent bands, may cyclically recede from a foreground to a background of the image frame(s), cyclically advance from a background to a foreground of the image frame(s), or cyclically move horizontally across the image frame(s). The overlay may be colorized to illustrate the height of the terrain underneath the overlay.

Abstract: In a transportation system (rail system or otherwise), a wayside device potentially operates in a plurality of operational modes. The wayside device is outfitted with an interface system for interfacing the wayside signal device with a vehicle control system. The interface system determines the present operational mode of the wayside device and independently communicates information relating to the determined present operational mode to the vehicle control system. The vehicle control system may control the vehicle based on the information relating to the determined present operational mode. The interface system includes functionality for validating the determined present operational mode prior to transmission of the information to the vehicle control system, to ensure that the vehicle control system is provided with correct and/or current information. The wayside device may be a wayside signal device whose operational modes (as determined by the interface system) are signal aspects conveyed to a vehicle.

Abstract: A method is provided for controlling movement of a plurality of vehicles over a guideway partitioned into a plurality of guideway blocks. The method uses a control system including an onboard computer (OBC) located on board each vehicle, at least one server for communicating with the OBCs, and a vehicle tracking system. The method including the steps of determining a composite block status for all guideway blocks, broadcasting the composite block status to the OBCs, and controlling movement of each vehicle based on the composite block status.
