A programming interface for a computer platform can include various functionality. The processor may include a first pipeline stage configured to generate data costs associated with a first tile selected from the first image, wherein the data costs is generated based on pixels in the first tile and corresponding pixels in the second image. This combination of elements substantially prevents exposure of the display unit to laundering-specific operating conditions, such as high temperature and elevated humidity conditions. The apparatus and methods further include receiving an indication of a selected data aggregation, as well as a selected function to carry out with respect to the selected data aggregation. One end of the actuator is connected to the drogue while the other end is connected to the refueling aircraft to form a triangular configuration, allowing only small interaction forces thereby restraining relative motion between the probe and the drogue.
