Abstract: An improved testing system and method for testing a flat-panel display is disclosed herein. A display is positioned under a high resolution camera for detection of, for example, brightness uniformity across the display. Errors in the detected image due to aliasing are avoided in the present invention by incrementally shifting the displayed image relative to the camera and detecting the displayed image at various shifted positions. A resulting accurate display can then be reconstructed by identifying those detector pixels generating a maximum signal. A single image may then be reconstructed using only those detected maximum pixel signals. The reconstructed image will be free of aliasing. The reconstructed image may then be analyzed electronically, and any anomalies in the pixels forming the display panel can then be accurately detected.

Abstract: An improved board game based upon American football; an improved board display and elements therefor including a scaled football field representation, score markers, down and quarter markers, ball position markers, and, as well, a reversible, invertible, largely transparent slide indicator actively cooperating with the field representation, which represents, successively, play moving from each end of the field and additionally serves as a strategy selector for both defense and offense; an array of probability (chance) dial selectors so presented and structured as to permit in depth representation and operation of all the features and facets of play of football on both defense and offense; a teaching device employing the subject board game and its apparatus elements.
