Abstract: A method for automatically undocking a passenger boarding bridge that is located in a docked position at a door of an aircraft, includes detecting a start signal to start the undocking procedure, confirming safety conditions, and automatically moving the passenger boarding bridge from the docking position to a parking position.

Abstract: A method for the automated docking of a passenger boarding bridge to an aircraft parked in a stand includes, determining a target position with respect to a door of the aircraft, to which target position a bridgehead of the passenger boarding bridge is to be moved, and moving the bridgehead to dock with the door of the aircraft based on the determined target position.

Abstract: A canopy for a passenger boarding bridge, includes a fixed frame, a flexible frame configured to align to a fuselage of a plane or a ship, a bellow roof clamped between the fixed frame and the flexible frame, and a suspension system. The suspension system includes a first cylinder actuator, and a second cylinder actuator, wherein the first cylinder actuator is configured to provide a pushing force in a first pushing direction and the second cylinder actuator is configured to provide a pushing force in a second pushing direction, wherein the first cylinder actuator and the second cylinder actuator are connected in series and the first pushing direction is opposite to the second pushing direction.

Abstract: A device that provides conditioned air to an aircraft may include a housing with a housing outlet end, a longitudinally collapsible hose that has a hose outlet for attachment to the aircraft and is partially received within the housing, a hose drive for extracting and retracting the hose by selectively pushing the hose in an outward or inwards directions, a drive control for controlling the hose drive, an outward marker attached to the hose, and a sensor for detecting the presence of the outward marker. The hose may have an extracted length that is at least twice a length of the housing. The hose may pass through the housing outlet end. The drive control may be adapted to respond to signals from the sensor to control the hose drive. Further, the marker may be adapted to provide a magnetic signal or a radio signal for detection by the sensor.
