SIGNAL PROCESSING FOR CONTINUOUS ANALYTE SENSOR
First Claim
1. A method for processing sensor data, the method comprising:
- receiving sensor data from a continuous analyte sensor;
receiving reference data from a reference analyte monitor measured at a reference time period;
estimating at least one analyte value based on the sensor data for the reference time period; and
forming at least one matched data pair by matching the reference data to the at least one estimated analyte value.

Abstract
Systems and methods for dynamically and intelligently estimating analyte data from a continuous analyte sensor, including receiving a data stream, selecting one of a plurality of algorithms, and employing the selected algorithm to estimate analyte values. Additional data processing includes evaluating the selected estimative algorithms, analyzing a variation of the estimated analyte values based on statistical, clinical, or physiological parameters, comparing the estimated analyte values with corresponding measure analyte values, and providing output to a user. Estimation can be used to compensate for time lag, match sensor data with corresponding reference data, warn of upcoming clinical risk, replace erroneous sensor data signals, and provide more timely analyte information encourage proactive behavior and preempt clinical risk.
