Abstract: Various embodiments are directed to a conveyor assembly and method of using the same. In various embodiments, a conveyor assembly may comprise a plurality of rollers defining a conveyor section configured for transporting one or more objects disposed thereon along a transportation path, wherein the plurality of rollers comprises a drive roller, the drive roller being selectively configurable between a first operating condition and a second operating condition; and a controller configured to generate one or more control signals to control the drive roller; wherein the conveyor section is selectively configurable between a single-zone configuration and a dual-zone configuration based on the configuration of the drive roller in one of the first operating condition and the second operating condition, the dual-zone configuration being defined by the drive roller selectively driving operation of a first conveyor zone and a second conveyor zone defined within the conveyor section independently of one another.

Abstract: A visual display system for an aircraft is provided. The system includes a database for storing obstacle information and a processor coupled to the database and configured to construct an obstacle warning envelope for the aircraft and receive obstacle information from the database based on the obstacle warning envelope. The processor is further configured to supply display commands associated with the obstacle warning envelope and the obstacle information. The system further includes a display device coupled the processor for receiving the display commands and operable to render a three-dimensional view, including the obstacle warning envelope and the obstacle. The display device provides a warning when the obstacle is within the obstacle warning envelope.
