Patent Images
1. A method, comprising:
- processing, using one or more processors, sampled data from analyte sensor;
determining, using the one or more processors, a single, fixed, normal sensitivity value associated with the analyte sensor;
estimating, using the one or more processors, a windowed offset value associated with the analyte sensor'"'"'s for each available sampled data cluster;
computing, using the one or more processors, a time varying offset based on the estimated windowed offset value; and
applying, using the one or more processors, the time varying offset and the determined normal sensitivity value to the processed sampled data to estimate an analyte level for the sensor.

Abstract
Methods and devices to detect analyte in body fluid are provided. Embodiments include processing sampled data from analyte sensor, determining a single, fixed, normal sensitivity value associated with the analyte sensor, estimating a windowed offset value associated with the analyte sensor for each available sampled data cluster, computing a time varying offset based on the estimated windowed offset value, and applying the time varying offset and the determined normal sensitivity value to the processed sampled data to estimate an analyte level for the sensor.
