Abstract:
1. A method for calibrating an analyte sensor, the method comprising: receiving sensor data from an analyte sensor, wherein the sensor data comprises one or more sensor data points; receiving reference data from a reference analyte monitor, wherein the reference data comprises a reference data point; predicting an estimated sensor data point from the one or more sensor data points for a time corresponding to a time stamp of the reference data point; matching the reference data point to the predicted, estimated sensor data point to compensate for a time lag of the one or more sensor data points relative to the reference data point; forming a calibration set comprising the reference data point and the predicted, estimated sensor data point; creating a conversion function based at least in part on the calibration set; and converting, using a processor, the sensor data into calibrated data using the conversion function, wherein the sensor data points are smoothed using a data smoothing filter, and wherein the time lag compensation is based at least in part on a time delay introduced by the data smoothing filter.
