1. A method, comprising:
- receiving, at one or more processors, glucose related data from an in vivo analyte sensor;
determining, using the one or more processors, a first filtered value associated with the received data based on a first predetermined time period and the received data;
determining, using the one or more processors, a second filtered value associated with the received data based on a second predetermined time period and the received data;
determining, using the one or more processors, a rate of change of the glucose level based, at least in part, on the received data;
determining, using the one or more processors, a variance in the rate of change of the glucose level;
generating, using the one or more processors, a weighted average value based upon the first filtered value, the second filtered value, a weighting function, the determined rate of change of the glucose level, and the determined variance in the rate of change of the glucose level;
determining, using the one or more processors, a third filtered value associated with the received data based on at least in part on the weighted average value and a predetermined parameter; and
modifying, using the one or more processors, the weighting function based upon the third filtered glucose value.

10. An apparatus including a glucose monitoring device, comprising:
-
a communication unit to receive glucose related data from a transcutaneously positioned in vivo glucose sensor; a processing unit coupled to the communication unit; and a memory storing instructions which, when executed by the processing unit, causes the processing unit to determine a first filtered value associated with the received data based on a first predetermined time period and the received data, to determine a second filtered value associated with the received data based on a second predetermined time period and the received data, to determine a rate of change of the glucose level based, at least in part, on the received data, to determine a variance in the rate of change of the glucose level, to generate a weighted average value based upon the first filtered value, the second filtered value, a weighting function, the determined rate of change of the glucose level, and the determined variance in the rate of change of the glucose level, to determine a third filtered value associated with the received data based at least in part on the weighted average value and a predetermined parameter, and to modify the weighting function based upon the third filtered glucose value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
