Abstract
Systems and methods for applying time-dependent algorithmic compensation functions to data output from a continuous analyte sensor. Some embodiments determine a time since sensor implantation and/or whether a newly initialized sensor has been used previously.
Claims43
A method of processing sensor data output by a continuous analyte sensor implanted within a body, comprising:
- generating sensor data using a continuous analyte sensor implanted within a body of a host;
- receiving and processing the sensor data output by the sensor using sensor electronics including a processor;
- measuring a change in sensitivity or baseline of the sensor over a time interval;
- determining a drift compensation function to be applied to a plurality of time-spaced data points output by the sensor over a next interval of time, wherein the drift compensation function is based at least in part on sensitivity information from a previous sensor session of the host;
- and
- applying the drift compensation function continuously to the data points over the next interval of time.

A system for processing data, the system comprising:
- a continuous analyte sensor configured to be implanted within a body of a host;
- and
- sensor electronics configured to receive and process sensor data output by the sensor, the sensor electronics including a processor configured to:
- measure a change in sensitivity or baseline of the sensor over an interval of time;
- determine a drift compensation function to be applied to a plurality of time-spaced data points output by the sensor over a next interval of time, wherein the drift compensation function is based at least in part on sensitivity information from a previous sensor session of the host;
- and
- apply the drift compensation function continuously to the data points over the next interval of time.
