1. An apparatus comprising:
- a filter unit to receive one or more signals based on blood glucose sensor measurements, the filter unit comprising one or more processors to;
determine one or more composite sensor glucose concentration values for a patient based, at least in part, on a combination of a plurality of estimated sensor glucose concentration values;
wherein the plurality of estimated sensor glucose concentration values are based, at least in part, on a plurality of functions for estimating a blood glucose concentration in the patient from sensor measurements based, at least in part, on a plurality of probability models; and
wherein the plurality of estimated sensor glucose concentration values are also based, at least in part, on a plurality of blood glucose reference sample-sensor measurement pairs.

Abstract
Disclosed are methods, apparatuses, etc. for calibrating glucose monitoring sensors and/or insulin delivery systems. In certain example embodiments, blood glucose reference samples may be correlated with sensor measurements with regard to a delay associated with the sensor measurements. In certain other example embodiments, a blood-glucose concentration in a patient may be determined based, at least in part, on one or more probability models, one or more functions for estimating blood-glucose concentrations, and/or blood glucose reference sample-sensor measurement pairs.
