Systems and methods for processing sensor data

Abstract

Systems and methods for processing sensor data are provided. In some embodiments, systems and methods are provided for calibration of a continuous analyte sensor. In some embodiments, systems and methods are provided for classification of a level of noise on a sensor signal. In some embodiments, systems and methods are provided for determining a rate of change for analyte concentration based on a continuous sensor signal. In some embodiments, systems and methods for alerting or alarming a patient based on prediction of glucose concentration are provided.

What is claimed is: 
     
         1 . A method for generating analyte measurements of a host, the method comprising:
 generating sensor data during a first time period using an analyte sensor coupled to a sensor electronics unit, wherein the sensor electronics unit is adhered to a body of a host;   receiving, using a receiver in wireless communication with the sensor electronics unit, a reference analyte value generated by a reference analyte monitor;   responsive to receiving the reference analyte value, determining a first estimated analyte concentration value to display using a first algorithm, wherein determining the first estimated analyte concentration to display includes using the reference analyte value in a first algorithm;   determining a second estimated analyte concentration value to display using the reference analyte value and the sensor data for the first time period in a second algorithm that is different from the first algorithm; and   displaying, on a display of the receiver, a numerical analyte value selected from the first estimated analyte value and the second estimated analyte value, wherein the first estimated analyte concentration value is selected as the displayed numerical value until the second estimated analyte concentration is available, and subsequently selecting the second estimated analyte concentration value to be the displayed numerical value.
