Transition code recognition system
US 3637993 A
Abstract
An electronic identification system for obtaining information from data-encoded labels in which a plurality of contiguous colored bars are printed on the data-encoded labels, each colored bar being of a color different from the color of its neighboring colored bars, is disclosed. The data-encoded label is scanned by a probe which images a spot of light on the label and which receives, from the label, reflected light signals that are supplied to the identification system. The identification system is constructed to receive and to decode a predetermined number of data bits according to a "size code" that is contained on the label, to perform a parity check of the data bits that are encoded on the label, and to transmit the decoded data to a data utilization device regardless of whether the probe traversed the label in a forward direction or in a reverse direction.
