Claim Text:
1. A method of operating a portable medical monitor system that generates an estimate of an analyte level of a patient being monitored with an analyte sensor, the method comprising: generating a current calibration curve for generating the estimate of the analyte level being monitored, wherein the current calibration curve is based on at least two measured data values of the level being monitored; determining a transformation function based on the current calibration curve and at least one preceding calibration curve such that the transformation function produces a predictive calibration curve that predicts changes to the current calibration curve resulting from sensor drift since the acquisition of the at least two measured data values used to generate the current calibration curve; generating an estimated level value of the analyte level being monitored, based on sensor output from the analyte sensor, in accordance with the predictive calibration curve; and causing medicament to be delivered to the patient with a portable infusion pump based on the estimated level value of the analyte being monitored.
