1. A method comprising:
- obtaining a sensor signal from a blood glucose sensor of a sensor component of an apparatus, the sensor signal being representative of a blood glucose concentration;
mapping a measurement of noise associated with the sensor signal to one of three or more discrete levels or values;
selecting an output signal for use in determining an estimate of the blood glucose concentration from among a plurality of distinct signal-filter paths arranged concurrently based, at least in part, on the one of three or more discrete levels or values;
generating one or more commands for an insulin delivery component of the apparatus based, at least in part, on the estimate of the blood glucose concentration; and
transmitting the generated one or more commands to the insulin delivery component to regulate a rate of fluid infusion into a body.

Abstract
Disclosed are a method and/or system for filtering sensor measurements. In one particular implementation, a sensor signal may be processed concurrently in a plurality of signal-filter paths. A particular signal-filter path may be selected to provide an output signal for obtaining a measurement based, at least in part, on a measurement of noise associated with the sensor signal.
