  • Patent number: 10958863
    Abstract: The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

  • Patent number: 9275293
    Abstract: A method and associated systems for object identification and subsequent processing based on digital imaging and physical attributes. An object-identification system receives, in a materials-handling environment, a digital image and physical attributes that characterize an unidentified object. An attempt is made to identify the object by matching the image and attributes to those of known objects stored in an image database, an attribute database, or another external source. The object is associated with a label that identifies the actual object, associates the object with a similar object that may be substituted for the actual object in a desired application, or designates the object as unidentifiable. The digital image, label, and external sources used to identify the object may be updated by associating them with metadata gathered during the identification process. Subsequent processing is governed by business rules that operate as functions of the label data.

  • Patent number: 9230140
    Abstract: Barcode verifiers automate the verification process by capturing an image of the printed barcode and analyzing the image according to an industry specification. Industry specifications (e.g., ISO/IEC 15416,15415) identify common printing errors and prescribe test methods for detecting and quantifying these errors. Typically, these tests sample a barcode along one or more scan lines. Print errors that are parallel to these scan lines may be missed by the test. The present invention embraces a system and method to detect unprinted lines in barcodes resulting from a printer malfunction and produce a printer malfunction report with information regarding the quantity, position, and magnitude of these print errors.

  • Patent number: 9104935
    Abstract: Systems and methods for use with a mark reader that reduce the trigger-to-decode response time by prioritizing images to be decoded based on the likelihood of a successful decode are provided. A reader attempts to decode a priority image(s) first to avoid attempting to decode images that are less likely than other images to be successfully decoded. Images are rated based on feature attributes, and then prioritized for decoding. Image feature attributes are correlated with parameter groups, and the parameter groups are prioritized for use in subsequent image acquisitions.

    Abstract: An indicia-reading system is provided that incorporates a hybrid approach to decoding indicia such as barcodes. An indicia-capturing subsystem acquires information about indicia within the indicia-capturing subsystem's field of view. An indicia-decoding module decodes indicia information acquired by the indicia-capturing subsystem. The indicia-decoding module includes a primary, basic signal processor for initially decoding indicia information, and a secondary, advanced signal processor for decoding indicia information that is not decoded by the primary, basic signal processor.

    Abstract: A process system for expediting the interpretation of information encoded or contained with an optical image capture for barcode decoding and machine vision applications that uses one or more each of which define one or more windows arranged according to equal rows or columns in the captured image that will be further processed to extract encoded or designer information. The scenarios and windows contained therein may be defined in memory and then recalled as needed based on the particular application so that multiple barcodes contained within a single image may be efficiently and expeditiously decoded.

  • Patent number: 8978985
    Abstract: The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

  • Patent number: 8967481
    Abstract: Techniques and systems for decoding optical codes using symbol-based algorithms are described. In one example, a method includes acquiring a signal representative of light reflected from an optical code comprising one or more symbols of a finite set of symbols and applying a decoding model to the signal. The decoding model may relate measured signals to the finite set of symbols, such that each of the symbols of the finite set of symbols are associated with a respective encoded character of a finite set of encoded characters. The method may also include determining, by a processor, a sequence of one or more of the encoded characters based on the application of the decoding model to the signal. In this manner, the optical code may be decoded by directly fitting an acquired signal from the optical code to possible symbols within the optical code and the associated encoded characters.

    Abstract: An optical reader for decoding an encoded symbol character of a symbology includes a scan data signal processor having as an input a scan data signal encoding information representative of the encoded symbol character. The scan data signal processor includes a first time delay stage adapted to provide a primary phase waveform from the scan data signal, a second time delay stage adapted to provide an early phase waveform from the scan data signal, and a third time delay stage adapted to provide a delayed phase waveform from the scan data signal. The early phase waveform has a propagation delay less than the primary phase waveform, and the delayed phase waveform has a propagation delay greater than the primary phase waveform. The scan data signal processor further includes a peak window detection stage for generating a peak window timeframe when an amplitude of the primary phase waveform is greater than, less than, or equal to both an amplitude of the early phase waveform and the delayed phase waveform.
