A metal crib bedstead includes a pair of symmetrical widthwise frames, a pair of symmetrical longitudinal frames, a mattress support frame and four elongated anchor planks. In one embodiment, individual inferior olive neurons are modeled in hardware, such as in an integrated circuit, and interconnected to form an artificial inferior olive. A first end of each feedthru wire is electrically coupled to a lead connector block. Also included is a generation module to transform the print features represented in the converted pixel map to a plurality of corresponding waveform features to produce the optical waveform of the selected marking, the corresponding waveform features including a plurality of spaced apart peaks representing respective optical signal levels of the print features.
