Abstract:
1. A computer implemented method for correcting a measurement of at least one sensor by estimating an offset of the at least one sensor, the method comprises: calculating combinations of running sums of temperature that are received from a temperature sensor and an associated offset that is derived from data received from the at least one sensor to compute one or more slopes for the at least one sensor, wherein the one or more slopes indicates how the estimated offset of the at least one sensor changes with temperature; wherein the calculating includes computing an average slope for a set of data from the at least one sensor that contains a fourth order equation of the distance along a temperature axis for all combination of pairs of points by using running sums of various powers of the data; and wherein the estimated offset is subtracted from the measurement of the at least one sensor to provide a corrected measurement by the at least one sensor.
