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.

Passenger bridge (100), comprising a proximal end (110), comprising a passenger passage opening (111); a distal end (120), comprising a bridge head (121); at least one first bridge segments (130), a proximal one (131) of which comprises, at the said proximal end (110), said passenger passage opening (111); at least one second segments (140), a distal one (142) of which comprises, at said distal end (120), the bridge head (121); a first support structure (150), arranged to support said first (130) and second (140) bridge segments so that at least one of said first segments (130) and at least one of said second segments (140) can be individually tilted; whereby the said first (130) and second (140) bridge segments together form a connected passage way for passengers between the proximal (110) and distal (120) ends, allowing the bridge head (121) to move vertically in relation the proximal end (110) by said bridge segments (130,140) tilting; characterised in that the length of the distal second bridge segment (142) can be telescopably adjusted, thereby moving the bridge head (121) horizontally in relation to the proximal end (110), and in that the passenger bridge (100) further comprises a second support structure (160), supporting the distal end (120) and being individually horizontally movable in relation to the first support structure (150).

Video messaging systems includes a plurality of camera systems, a plurality of network-based clients, a messaging hub communicatively connectable to the plurality of network-based clients, and a video frame transmission service communicatively connected to the messaging hub. The messaging hub is configured to transmit image data as encoded data to each of the plurality of network-based clients. The video frame transmission service is configured to selectively connect with at least one of the plurality of camera systems for a time period that is based upon a request received from at least one of the plurality of network-based clients.

Event recognition systems include a camera and a controller. The controller is communicatively connectable to the camera, and includes a processor and logic that, when executed by the processor, causes the event recognition system to perform operations including: recognizing an event involving an equipment object based upon image data captured by the camera, executing an event procedure based upon the event, the event procedure including controlling the equipment object, and transmitting the image data to a network-based client based upon the event.

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.

Event recognition methods include executing, with a controller, an algorithm which receives image data as an input and recognizes a first equipment object and a second equipment object in the image data; recognizing an event involving the first equipment object and the second equipment object based upon the image data using the controller; executing an event procedure based upon the event, wherein the event procedure includes controlling the first equipment object using the controller; and transmitting the image data to a network-based client based upon the event.

An aircraft boarding apparatus has a passenger bridge that has a confinement structure coupled to the second passenger bridge. The confinement structure exerts a ground-anchoring effect on the second passenger bridge to offset the ultralight configuration of the passenger bridge.
