SIGNAL PROCESSING FOR CONTINUOUS ANALYTE SENSOR
First Claim
1. A method for compensating for a time lag of continuous analyte sensor data, the method comprising:
- receiving sensor data from a continuous analyte sensor, wherein the sensor data comprises a) a physiological time lag with respect to blood analyte data or reference analyte data, b) a membrane-induced time lag, and/or c) a computationally-induced time lag;
continuously and/or intermittently estimating one or more analyte values based on the sensor data, wherein the step of estimating comprises compensating for a time lag associated with the sensor data; and
continuously and/or intermittently providing an output based on the time-lag compensated estimated analyte values.

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.
