Abstract: A method of controlling purge of a fuel cell system for a vehicle is provided. The method determines whether a purge function is normally performed in controlling purge of discharging nitrogen, hydrogen, and vapor within an anode of a fuel cell system. Particularly, the method confirms whether purge is performed by measuring a duty or a current applied to a hydrogen supply valve and measuring a change in the duty before and after an application of a purge valve operation command while adjusting a pressure inside the anode, which supplies hydrogen, to be uniform. Further, a hydrogen supply amount supplied into an anode is estimated and a change rate of a hydrogen supply amount supplied to the anode and a hydrogen amount consumed during a generation of the fuel cell system are estimated during a purge function, to determine whether purge is actually performed based on the estimated information.

Abstract: A biosensor system determines analyte concentration from an output signal generated from a light-identifiable species or a redox reaction of the analyte. The biosensor system adjusts a correlation for determining analyte concentrations from output signals or determined analyte concentrations with one or more complex index function extracted from the output signals or from other sources. The complex index functions determine at least one slope deviation value, ?S, or normalized slope deviation from one or more error parameters. The slope-adjusted correlation between analyte concentrations and output signals may be used to determine analyte concentrations having improved accuracy and/or precision from output signals including components attributable to bias.
