Abstract: Areal weight or thickness of a moving coated metal sheet along its entire cross directional width is derived by correlating thermographic image data to online, scanning basis weight measurements. Thermal imaging camera captures thermal images of a heated moving coated metal sheet material along a cross direction at a first position along the machine direction to generate sequential temperature profiles. Scanning beta gauge measures the areal weight of the moving coated metal sheet downstream at a second position. An infrared temperature sensor also measures the temperature of the moving coated metal sheet which is at a lower temperature at or near the second position. The temperature differential between the cross directional thermographic image data and the latter infrared temperature is a function of the basis weight. Basis weight measurements from the beta gauge is used to extrapolate cross directional basis weight data.

Abstract: A method for inertial sensor error modeling and compensation comprises obtaining multiple bias drift datasets for an elapsed time period for one or more gyroscopes; generating a 3D bias drift data plot using the multiple bias drift datasets; generating a partial bias drift data image based on the 3D bias drift data plot; and inputting the partial bias drift data image into a machine learning algorithm to predict how bias drift evolves over time for the gyroscopes. The machine learning algorithm uses the partial bias drift data image, the elapsed time period, and temperature history to compute a predicted bias over temperature with respect to time, to thereby predict bias drift data for a future time period for the gyroscopes. The machine learning algorithm outputs a completed bias drift image that represents drift data from the elapsed time period and the predicted bias drift data for the future time period.
