Machine-readable coded data disposed on or in a substrate. The frame comprises a housing open at a front and a rear to form a central passageway along an axis at an oblique angle with respect to the horizon. A control current is applied to the at least one photon emission device. Once the elevator stops, the pusher component will advance to move the column of bottles into the rack. The method and system include: powering down the second integrated circuit chip; tri-stating a plurality of inputoutput drivers of the second integrated circuit chip so that the plurality of IO drivers do not drive any signals onto any connections for the shared external terminals; and performing testing of the first integrated circuit chip according to one or more regular testing routines.
