Abstract: A cargo loading alignment device is integrally mounted to a movable cargo transport. The transport has a cargo door opening and loading ramp with a longitudinal centerline, and the alignment device is installed near the cargo door opening. The device includes at least one light source for projecting at least one beam of light onto the loading surface, for visually indicating a desired alignment of a delivery vehicle for transferring cargo to and from the transport. A preferred embodiment of the device includes a light source for projecting a first and a second planer beam of light perpendicularly to the centerline of the loading ramp; and a third planer beam of light extending parallel or coinciding with the centerline of the loading ramp.

Abstract: A visual guidance system and method includes a subsystem which both locates the aircraft and mating structures thereof and also determines their motion and their rate of change of motion. The locating subsystem has an electrical output which feeds the location and motion data to a guidance system computer which utilizes software which combines the data with other data in a database containing the dimensional size and configuration of the aircraft and mating structures. The combined data is converted to a suitable form and fed to the computer monitor which displays the aircraft and mating structures thereof in real time during the refueling operation. The computer and computer monitor are provided with image controls which allow the operator to select the perspective viewing angle as well as the image contrast and color in order to enhance the visual cues provided by the image and facilitate the refueling operation.

Abstract: This display system comprises, front to rear, an electro-luminescent information bearing display element which is substantially transparent when not energized, a background element which is dark (opaque) when it is energized and substantially transparent when not energized, and a backup display means which is visible when the two front elements are not energized.

Abstract: A display system is constructed such that upon failure of the primary display which comprises a Liquid Crystal Display (LCD) that becomes transparent upon failure, a backup display located directly beneath the primary display becomes visible to the display user.
