POS Optical scanning station

An analog to digital wave shaping system comprising, a source of analog signals, adaptive threshold circuitry coupled to said source, said adaptive threshold circuitry having an output selected as a function of the intensity of said analog signal compared to a fixed intensity signal, and, comparator circuitry coupled to said source and to the output of said adaptive threshold circuitry.

Analog to digital wave shaping system

A symbol decoding system for decoding symbols comprised of plurality of bars some of which representing characters, comprising, means for providing a series of pulses representative of said bars, means for counting the interval between positive transitions between adjacent pulses, means for counting the interval between negative transitions between adjacent pulses, means for storing said counted intervals, means for testing for certain predetermined relationships among said counted intervals, and means identifying particular characters whenever said predetermined relationships are satisfied.

UPC symbol decoding system

Optical scanning apparatus for scanning and sensing information contained on a label-bearing article includes a light source, a rotatable member having a reflective surface, optical means for directing light from the source to the reflective surface and optical means for directing light reflected from the reflective surface to form a scanning pattern on a predetermined plane; the scanning pattern being comprised of a plurality of segments together forming at least one pair of overlapping X-shaped traces.

Retro-reflective multiple-X optical scanning system

An optical scanning station includes means for generating a predetermined scanning pattern along a given plane, and a member embodying said scanning pattern in the form of open slots substantially coincident with said given plane.
