The passenger boarding includes a rotunda, a tunnel portion, a cab and a first detection device configured to detect an angle of the rotunda from the first axis around an origin point, and a second detector configured to measure a distance of the tunnel from the origin point in the extensible/contractable direction, provided at the tunnel.

A passenger boarding bridge includes: a rotunda rotatable about a vertical axis; a tunnel unit; a cab; a lifting/lowering mechanism; and a travel unit. A control method includes, at a time of docking the cab with an entrance of an aircraft: calculating relative positional information indicating a position of the entrance as seen from the cab when the travel unit is at a movement start position; calculating positional information of a destination position based on the movement start position and the relative positional information in a case where a distance from the movement start position to the destination position is less than a horizontal distance from the vertical axis to a center point of the travel unit; calculating a target travel angle; and controlling the travel unit such that a travel angle of the travel unit is kept to the target travel angle during traveling.

A method for calculating an optimal wheel position control angle of passenger boarding bridge automatic docking system includes collecting ranging information of a sensor to rotate the bridgehead direction via a distance measuring sensor on both sides of the bridgehead of the passenger boarding bridge, making the bridgehead parallel to the aircraft fuselage; collecting information of an aircraft door by a camera at the bridge head of the passenger boarding bridge to obtain a center position D of the aircraft door; in an ideal docking situation, the aircraft door should appear at the bridge head position as D″; the position where D″ is projected vertically onto the aircraft fuselage is D′, that is, the line segment DD′ is the horizontal distance deviation between the current passenger boarding bridge and the aircraft door, the line segment D′D″ is the distance between the current boarding bridge and the aircraft fuselage.

Provided is a passenger boarding bridge that includes: a rotunda connected to a terminal building and supported in a horizontally rotatable manner; a tunnel unit whose proximal end is connected to the rotunda, the tunnel unit being extendable and retractable; a travel device that supports the tunnel unit and includes travel wheels, the travel device being configured such that a travel direction of forward travel of the travel wheels and a travel direction of backward travel of the travel wheels are changeable; a cab provided at a distal end of the tunnel unit, the cab being configured to be docked with an aircraft; and a determiner configured to, at a time before undocking the cab docked with the aircraft from the aircraft, perform determination whether or not the travel direction of the backward travel of the travel wheels at the time is a direction within a smooth undocking range.

A linear actuator assembly includes a motor. The linear actuator assembly also includes a ball screw rotatably driven by the motor. The linear actuator assembly further includes a nut coupled to the ball screw and rotationally fixed, the nut translatable along the ball screw upon rotation of the ball screw. The linear actuator assembly yet further includes a flange having a first surface and a second surface, the nut mounted to the first surface and the second surface having a non-planar geometry, the non-planar geometry defined by curvature about an axis from a first side of the flange to a second side of the flange, the first side and the second side of the flange being on opposite sides of the flange from each other.

A jalousi wall assembly for a passenger bridge, which jalousi wall assembly including a first jalousi wall in turn having a first end and a second end, which first end is arranged to be wound up on, and off from, a first roll with a first vertical rotation axis (A2), and which second end is arranged to be fastened to the passenger bridge, wherein the first roll is arranged to be fastened to the frame of a movable opening of the passenger bridge and to follow horizontal movements of the frame by the first jalousi wall being wound up on, or off from, the first roll, whereby a horizontal length of the first jalousi wall, between the first end and the second end, is adjusted in response to a horizontal movement of the frame. The application relates to a jalousi wall assembly further including a wire having a first and a second end, which first end is wound about the first vertical rotation axis (A2) such that the first jalousi wall is wound up on the first roll when the wire is pulled at its second end, and in that the jalousi wall assembly further includes a wire tension device including a gas spring arranged to maintain a tension in the wire while the frame moves.

A passenger bridge including a least one passenger bridge end segment; a bridge head, arranged at a distal end of said bridge end segment; a cabin, arranged to move about an outer periphery of the bridge head and comprising a door for passengers; and a cabin suspension, arranged to allow the cabin to rotate in relation to the bridge head about a vertical axis (A1). The application further relates to a cabin suspension including a pivot arm in journaled engagement with an upper part of the bridge head so that the cabin can swing in a first horizontal plane (P1), and in that a cabin holding part of the pivot arm is fastened to an upper part of the cabin, whereby the cabin hangs from the said cabin holding part.

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.

A system is provided that guides aircraft driven with landing gear wheel-mounted electric taxi drive systems without reliance on airport ground personnel to park the aircraft parallel to an airport terminal with connections to multiple passenger loading bridges, automatically docks the aircraft, and connects the multiple loading bridges to multiple forward and rear doors. Cooperative on-aircraft monitoring systems, airport docking systems, loading bridge and terminal monitoring systems, and processors are integrated to use real time information and guide the aircraft to safely maneuver into and automatically dock in a parallel orientation at a parking location with multiple aircraft forward and rear doors connected to multiple loading bridges. The system may automatically undock the aircraft and retract the loading bridges and guide the electric taxi drive system-driven aircraft out of the parking location without reliance on airport ground personnel.

A device may receive one or more images that depict one or more shapes associated with a first object that includes a portal. The device may identify, based on the one or more images, one or more characteristics of the one or more shapes. The device may determine, based on the one or more characteristics of the one or more shapes, one or more attributes of the portal. The device may determine, based on the one or more attributes of the portal, positioning information to be used to position a second object relative to the portal of the first object. The device may output, based on the positioning information, one or more control signals associated with positioning the second object relative to the portal.
