    摘要: A dual function solid state power converter operable from a three phase AC input current simultaneously provides; an AC or DC output current on an aircraft power cable which extends from a stowed position to provide ground power to a parked aircraft, and a low voltage DC current on a battery charging power cable which extends from a stowed position to charge batteries in nearby service vehicles. The power converter includes an AC to DC converter which converts the AC input current to a DC current on an internal DC bus, a DC to AC converter which converts the DC bus current to an AC current at a higher voltage and frequency, or a DC to DC converter which converts the DC bus current to a lower voltage DC, for supplying ground power by means of a connecting cable to a parked aircraft, and a DC to DC converter for converting the DC bus current to a lower voltage battery charging current on the battery charging cable. In an airport environment the power converter may be advantageously mounted on a passenger boarding bridge and a motion inhibit circuit may be provided to prevent movement of the boarding bridge when either the aircraft ground power cable or battery charging cable are not in a stowed position. The power converter may also be mounted on a wheeled cart for positioning by a tug, or installed in a remote stationary position.

    摘要: A device may obtain, from one or more cameras, an image that depicts one or more encoded decals positioned on a body of a vehicle. The device may process the image and may identify, based on processing the image, one or more characteristics of the one or more encoded decals. The device may determine, based on the one or more characteristics of the one or more encoded decals, positioning information to be used to position a loading bridge relative to the body of the vehicle. The device may determine one or more control signals based on the positioning information. The device may provide the one or more control signals to one or more actuators to automatically position the loading bridge relative to the body of the vehicle.

    摘要: A method for positioning an access or loading assembly against the fuselage of an aircraft during the loading or unloading process, in which at least two multichannel scanners are oriented toward the aircraft fuselage and disposed above one another at a distance from each other, each with several light emitting units and at least one detector. First, a reference position is determined by using the scanners, then a current position of the aircraft fuselage relative to the access or loading assembly is determined at determined time intervals by the multichannel scanners. The current position is compared with the reference position to determine a deviation. In case of a deviation between the two positions, a signal is transmitted to the control system of the positioning drive for realigning the access or loading assembly and reducing the deviation.
