  • Patent number: 9495564
    Abstract: A reader electro-optically reads symbols by image capture to obtain read data, and a controller processes symbol images of the symbols captured by the reader, and decodes the read data to obtain symbol data indicative of the associated products. The controller also collects time-to-decode metadata by determining the decode time periods that are taken for the symbol data to be successfully decoded, associates the decode time periods with the symbol images, stores the longest decode time period and its associated symbol image, and displays the stored symbol image associated with the stored longest decode time period to determine a cause of the reading performance of the reader.

  • Patent number: 9489554
    Abstract: A reader electro-optically reads symbols associated with products to obtain read data, and a controller decodes the read data to obtain symbol data indicative of the associated products. Reading performance is assessed by collecting time-to-decode metadata by determining each decode time period that is taken for each symbol data to be successfully decoded, by associating the collected time-to-decode metadata with the symbol data, by comparing the collected time-to-decode metadata with a predetermined long amount of decode time that is indicative of a slow reading performance, by storing each decode time period that at least equals said predetermined long amount of decode time, and by storing the symbol data associated with each stored decode time period.

  • Patent number: 8950676
    Abstract: An arrangement for, and a method of, electro-optically reading a target by image capture, employ an aiming assembly for projecting an aiming light pattern on the target that is located within a range of working distances relative to a housing, an imaging assembly for capturing an image of the target and of the aiming light pattern over a field of view, and for generating an electrical signal indicative of the captured image, and a controller for determining a distance of the target relative to the housing based on a position of the aiming light pattern in the captured image, and for processing the electrical signal into information relating to the target when the target lies in a restricted zone within the range of working distances.

  • Patent number: 8579198
    Abstract: A laser scanning device is described. The device includes a laser for projecting a light beam. A mirror is optically coupled to the laser. The mirror reflects the light beam onto a target. A detector generates an analog signal in response to detecting a reflection of the light beam from the target. A processor is capable of modifying a scanning parameter of the laser scanning device. The processor processes the analog signal to generate a digital bar pattern and can embed the scanning parameter in the digital bar pattern.

  • Patent number: 8376234
    Abstract: Symbols having symbologies with multi-unit, bar and space element, start and stop patterns on curved surfaces of objects, are electro-optically read by capturing light from a target symbol over a scan line, and by generating an electrical analog signal indicative of the captured light over the scan line. A controller digitizes the electrical analog signal into a digitized signal, decodes the digitized signal between the start and stop patterns into valid characters of the target symbol, identifies leading and trailing waveform portions of the analog signal indicative of the start and stop patterns, matches the identified leading and trailing waveform portions of the analog signal against known analog waveforms of the start and stop patterns of the target symbol, and verifies that a match has occurred when the matching between the leading and trailing waveform portions and the known analog waveforms exceeds a known threshold correlation.

  • Publication number: 20110073657
    Abstract: A method and apparatus for detecting a barcode like region contained in a target object. The method includes capturing an image of the target object, calculating a total confidence value for the captured image, and determining a presence of a barcode in the captured image based on the total confidence value, wherein the total confidence value is calculated as a function of at least one of a first, second, and third confidence values. The method of calculating the confidence values includes calculating the first confidence value based on a vertical projection signal of the barcode like region in the captured image, the second confidence value based on a horizontal projection signal of the barcode like region in the captured image, and the third confidence value based on a start and stop pattern of the barcode like region in the captured image.
