Abstract: A track changing apparatus for changing a track on an armored vehicle includes a plurality of moveable elements. The plurality of moveable elements of the track changing apparatus allows a track to be manipulated from loose or unmounted state, to a tensioned state wherein the track is located on the track changing apparatus, and finally, to a fully mounted state wherein the track has been transferred onto the armored vehicle. In at least one embodiment, the track changing apparatus may be used to remove a track from an armored vehicle. Methods of using a track changing apparatus are also described, including a method of mounting a track onto an armored vehicle.

Abstract: A method of aligning one end of a passenger boarding bridge with a doorway of an aircraft includes a step of parking the aircraft within a parking space that is defined adjacent to the passenger boarding bridge. Human intelligible information visually displayed proximate the parking space is determined, the human-intelligible information being uniquely associated with the passenger boarding bridge. Using an input device that is disposed aboard the aircraft, the human-intelligible information is provided to a communication module that is also disposed aboard the aircraft. A signal including the human-intelligible information is transmitted from the communication module to a receiver that is in communication with the passenger boarding bridge. Only signals determined to include the human-intelligible information are accepted as valid signals during a current bridge alignment operation.
