The present invention provides a hollow IM-5 molecular sieve sphere and the preparation process thereof. The method performs skew correction and connected component analysis on the check image and removes components smaller than average size before identifying the regions using projection profiles. The aerodynamic boundary so generated replaces mechanically moveable solid surfaces used to vary the geometry of prior-art intakes. A programmed processing system is operatively coupled to the memory and the projector for generating a series of images to be projected by the projector. The vehicle has a loading edge, where loading edge exhibits a slant for supporting the loading floor at a second end region.
