  • Patent number: 6082621
    Abstract: A multi-bit digitizer (30) for a barcode reader detects the presence of edges of a scanned barcode symbol, and also measures the strength of each detected edge. A polarity or edge direction signal (8) indicates the direction of each detected edge, and a timing signal (6) is representative of the timing and also, by means of a variable pulse width, the strength of each edge. A gating signal (200) indicates that the data are unreliable and invalid if the measured voltage applied to the scanner motor of the barcode reader is higher or lower than defined limit values. Any scans made at a speed which were too high or too low are rejected.

  • Patent number: 5734152
    Abstract: An optical scanning system is provided for producing a signal representative of a spatial distribution of indicia having different degrees of reflectivity to light, such as a bar code. The system includes an optical scanner for scanning beam of light over the spatial distribution of indicia and for producing an electrical signal corresponding to changes in the degree of reflectivity of the indicia. A digitizer, responsive to detections in a predetermined characteristic of the produced electrical signal is provided. The digitizer converts the detections into digital words, such digital signals having a plurality of bits. The digitizer includes a timing generation circuit for producing a pulse in response to each one of the detections with a time duration representative of the degree of reflectivity of the indicia as the beam of light. A decoder converts the time duration of the pulse into the digital word having a plurality of bits. An enhancement filter is also disclosed.
