Abstract
An arrangement (apparatus and method) using fuzzy logic for determining the ratios of barcode elements with respect to a reference barcode element. A barcode interface outputs width data for the reference barcode element and the other barcode elements of the barcode pattern in accordance with a predetermined barcode format. A latch array latches the width data of the reference barcode element and supplies the reference width data and a divided value of the reference width data to a fuzzy microcontroller as center and width data for a fuzzy membership function, respectively. The latch array also latches the barcode element width data from the barcode interface, divides the barcode element width data by a set of predetermined ratios, and outputs the quotient data to the fuzzy microcontroller. Each quotient data corresponding to one of the ratios is fuzzified by determining the distance of the crisp input from the center of the membership function and linearly complementing the distance with respect to the width of the membership function. The quotient data that has the highest membership value is deemed to correspond to the winning ratio. The fuzzy microcontroller uses rule-based logic that enables code recognition of the barcode scanner on the basis of successive determined ratios, as well as control of external devices in response to the determined ratios.
