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.
Claims25
A method comprising:
- providing a signal representative of a blood glucose concentration;
- and
- selecting an output signal for use in estimating said blood glucose concentration from among a plurality of signal-filter paths based, at least in part, on a measurement of noise associated with said signal.
An apparatus comprising:
- means for providing a signal representative of a blood glucose concentration;
- and
- means for selecting an output signal for use in estimating said blood glucose concentration from among a plurality of signal-filter paths based, at least in part, on a measurement of noise associated with said signal.
An apparatus comprising:
- a blood-glucose sensor to generate a sensor signal representative of a blood-glucose concentration in a patient;
- and
- a controller adapted to select an output signal for use in estimating said blood glucose concentration from among a plurality of signal-filter paths based, at least in part, on a measurement of noise associated with said sensor signal.
An article comprising:
- a storage medium comprising machine-readable instructions which, if executed by a computing platform, are adapted to direct said computing platform to:
- select an output signal for use in estimating a blood glucose concentration from among a plurality of signal-filter paths based, at least in part, on a measurement of noise associated with a signal representative of a blood-glucose concentration.
