Patent ID: 8670815

Claim:
A system, comprising: a glucose sensor that produces a data stream indicative of a glucose concentration, the data stream comprising a plurality of time spaced sensor data points; a receiver that receives the data stream from the glucose sensor, wherein the receiver comprises: a processor; and a computer readable memory comprising: instructions configured to cause the processor to determine if calibration of the glucose sensor is appropriate; instructions configured to cause the processor to evaluate a change in at least one characteristic associated with the glucose sensor; instructions configured to cause the processor to determine a rate of change of the data stream from the glucose sensor; and instructions configured to cause the processor to not recalibrate or not update calibration of the glucose sensor when the rate of change of the data stream is above a threshold rate and when the evaluation of the change in the at least one characteristic is not indicative of the change in the at least one characteristic of the glucose sensor.
