Patent ID: 8574895

Claim:
A device for use in a metering device for measuring analyte levels in a sample fluid, said device comprising: a housing a controllable electronic driver; a plurality of penetrating members; a cartridge; a plurality of analyte detecting members positioned in the cartridge and each of an analyte detecting member being associated with a penetrating member, each of said detecting member providing an indicator of analyte levels in said sample fluid, wherein the analyte detecting member comprises natural pyrolloquiniline quinone (PQQ) and used in conjunction with an autooxidisable electron acceptor: a processor in communication with at least one of the plurality of detecting members, the processor configured to provide for compensation of fixed pattern noise in the at least one of the plurality of detectors and reduce frame rates, with different fixed pattern noise to detect signals from different analyte detecting members; the cartridge housing the plurality of penetrating members and analyte detecting members; and a cartridge advancement device coupled to the cartridge in the housing and in operation configured to move the cartridge through an angle equal to an angular spacing from a centerline of one of the penetrating members to a centerline of an adjacent penetrating member.
