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.
