PREDICTIVE CALIBRATION
First Claim
1. A method of operating a portable medical monitor system that generates an estimate of an analyte level being monitored, the method comprising:
- generating a calibration curve for generating the estimate of the analyte level being monitored, wherein the calibration curve is based on at least two 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;
generating an estimated level value of the analyte level being monitored, based on sensor output from a sensor associated with the portable medical monitor system, in accordance with the predictive calibration curve.

Abstract
A portable medical monitor system generates a current calibration curve for generating the estimate of the level of an analyte, such as glucose, being monitored. The current calibration curve is based on at least two measured data values of the level being monitored. The system determines a transformation function based on the calibration curve and at least one preceding calibration curve such that the transformation function produces a predictive calibration curve, and generates an estimated level value of the level being monitored, based on sensor output from a sensor associated with the portable medical monitor system, in accordance with the predictive calibration curve.
