An interactive doll is disclosed having one or more sensors contained therein. A self terminating pre-charge section is connected to the input section and includes domino logic. The normalized calibration information includes a normalization relationship to normalize output signals measured by the measurement device of the biosensor system and at least one normalized reference correlation relating normalized output signals to reference sample analyte concentrations. The screen segments include magnetic elements with exposed poles that match the outward facing pole of the corresponding sets of magnetic elements on the vehicle. The volume is configured to complementarily receive the card in order to display advertising indicia disposed on the front of the card.
