Patent ID: 7392144

Claim:
A method for generating a calibration data curve, comprising the steps of: determining a first target value that corresponds to a predetermined coordinate of a first selected data point that corresponds to the data curve; determining a second target value that corresponds to a predetermined coordinate of a second selected data point that corresponds to the data curve; determining a predicted third target value based on the first target value, the second target value, and a first predetermined predictor function; determining an actual third target value that corresponds to a predetermined coordinate of a third selected data point that corresponds to the data curve; determining a first correction between the predicted third target value and the actual third target value; determining a predicted fourth target value based on the first target value, the second target value, the actual third target value, and a second predetermined predictor function; determining an actual fourth target value that corresponds to a predetermined coordinate of a fourth selected data point that corresponds to the data curve; determining a second correction between the predicted fourth target value and the actual fourth target value; and generating a calibration data curve based on the first selected data point the second selected data point, the third selected data point and the fourth selected data point.
