Patent ID: 7225652

Claim:
A graphical flatness display for a rolled steel sheet, comprising: at least one sensor for measuring a property of a rolled steel sheet at a plurality of locations on the rolled steel sheet and producing a property output signal corresponding to a magnitude of the sensed property at each of the plurality of locations; a processor operatively connected to the at least one sensor for receiving said sensor property output signals, a memory operatively connected to said processor storing property magnitude ranges and a color corresponding to each of said property magnitude ranges; and a color display operatively connected to said processor; wherein said processor receives a property output signal, determines the property magnitude range indicated by said received property output signal, and plots a point in the color corresponding to the determined property magnitude range on the display at a point on the display related to the location on the rolled steel sheet at which the property was sensed, wherein said processor produces an output for creating a first graphical image comprising a color illustration of a flat surface of the sheet of rolled steel and a second graphical image comprising a waterfall plot of the average tensions values.
