A stereoscopic image display includes a display panel, which selectively displays a 2D image and a 3D image and includes a plurality of pixels, and a patterned retarder for dividing light from the display panel into first polarized light and second polarized light. The circuit also includes an output voltage for providing an adjustable drive voltage to a drive circuit. By combining a continually updated database of computing system performance with the ability to analyze that information to detect faults and then communicating that fault information to correct the fault or provide appropriate notification of the fault results in achieving the goals of high availability and operational readiness. The earth shaping apparatus further has a ditching blade coupled to the earth shaping apparatus in front of the leveling blade with respect to the ditching direction.
