First Claim
Patent Images
1. A method of analyzing data from an analyte sensor, the method comprising:
- receiving data from the analyte sensor, the data comprising at least one sensor data point;
determining whether a signal artifact event has occurred; and
processing the received data, wherein the processing is based at least in part upon whether the signal artifact event has occurred.

Abstract
Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as interfering species, ischemia, pH changes, temperatures changes, known or unknown sources of mechanical, electrical and/or biochemical noise, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system processes some or the entire data stream continually or intermittently based at least in part on whether the signal artifact event has occurred.

20. A system configured to process data from an analyte sensor, the system comprising:
-
a data receiving module configured to receive sensor data from the analyte sensor, the data comprising at least one sensor data point; a signal artifacts module configured to detect a signal artifact in the sensor data; and a processor module configured to process the sensor data, wherein processing is dependent at least in part upon whether the signal artifact is detected.
