  • Patent number: 10311271
    Abstract: One aspect of the present disclosure is related to a barcode reader that includes a bright field illumination system, a dark field illumination system, and an additional illumination system that is better able to illuminate an area of the reader's field of view between the far zone (where bright field illumination is optimal) and the close zone (where dark field illumination is optimal). In this “center zone,” the dark field illumination may not be bright enough and the bright field illumination may not be diffuse enough for reading a barcode.

  • Patent number: 9928392
    Abstract: A barcode-reading system may include a barcode-reading enhancement accessory that is securable to a mobile device. The accessory may include an optic system that is configured to shape and filter illumination from a white light source of the mobile device to project targeting illumination onto a target surface. Calibration data may indicate a relationship between surface distance and at least one feature offset of the targeting illumination. A barcode-reading application may determine a feature offset of the targeting illumination in an image that is captured by the camera assembly of the mobile device. The application may also determine an estimated surface distance based on the calibration data and the feature offset. The application may also use the estimated surface distance to adjust at least one operating parameter of the mobile device.

  • Patent number: 9922128
    Abstract: This patent specification describes a barcode-reading system for a mobile device. The mobile device include an image sensor array for generating a color image of a target area. The color image includes sub-images each captured with a portion of the image sensor array sensitive to different bands of illumination. The barcode reading system may include an optic system configured to produce a targeting illumination pattern of a particular band of illumination passed by an optical filter within the target area. An image processing function of a barcode-reading application may create a grayscale composite image of a barcode by combining the sub-images. In combining the sub-images, a contribution from a sub-image captured by a portion of the image sensor array most sensitive to the particular band for the targeting illumination may be smaller than a contribution from the other two sub-images captured by other portions of the image sensor array.

Alternately, the data reader is operable to switch between handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change within or between frames.

  • Patent number: 8479993
    Abstract: A method of operating a barcode reader. The method includes (1) detecting a first pulling of the trigger while the barcode reader is at the waiting mode; (2) detecting a first release of the trigger within a first predetermined time period after the first pulling of the trigger is detected, for operating the barcode reader in the aiming mode if the first release of the trigger is detected within the first predetermined time period,; and (3) detecting a second pulling of the trigger while the barcode reader is at the aiming mode within a second predetermined time period after the first release of the trigger is detected, for operating the barcode reader in the decoding mode if the second pulling of the trigger is detected within the second predetermined time period.

  • Patent number: 8322617
    Abstract: Systems and methods are provided for selectively reading and accepting optical codes within a scan volume of the data reader. A method of processing an optical code within the scan volume comprises acquiring, via the data reader, scan data including an image or scan of an optical code located within the scan volume of the data reader, processing the scan data for decodable data corresponding to the optical code, and determining whether to accept or reject the optical code based on a position within the scan volume of the optical code relative to a configurable exclusion zone. The determination of whether to accept or reject the optical code may be based on other conditions of the optical code, such as a position of the optical code within the depth of field of the data reader, a symbology type of the optical code, and data encoded in the optical code.

  • Patent number: 8313031
    Abstract: An apparatus and method is provided for focusing an image of a target object. The apparatus comprises imaging circuitry for analyzing an image reflected from a target object that is projected onto an imaging sensor coupled to the imaging circuitry. A fixed imaging lens having an optical axis in alignment with the imaging sensor focuses the reflected image onto the imaging sensor. One of a plurality of apertures located within a selectable aperture of varying sizes is selected for optically enhancing the fixed imaging lens. An actuator is coupled to the selectable aperture for selectively selecting the one of the plurality of apertures in a direction transverse to optical axis for optically enhancing the fixed imaging lens.

  • Patent number: 8305192
    Abstract: A dual-mode RFID reader is capable of automatically switching from a far-field interrogation mode to a near-field interrogation mode upon the detection of certain operating or handling conditions. The RFID reader includes an RFID radio module configured to support a far-field interrogation mode and a near-field interrogation mode, an antenna arrangement coupled to the RFID radio module, and a mode-switch sensor architecture coupled to the RFID radio module. The mode-switch sensor architecture is configured to detect conditions indicative of near-field interrogation, and the RFID radio module automatically configures itself for operation in the near-field interrogation mode upon detection of such conditions.

  • Patent number: 8215564
    Abstract: Methods for efficiently retrieving information from an image of a symbol are described. Symbols are described that contain detection patterns that facilitate the determination of location, alignment, size and orientation of the symbol in an image. Detection patterns are described that possess geometric shapes susceptible to efficient decoding using probabilistic detection algorithms. Detection patterns are described that are provided in colors, shapes and sizes different from the color, shape and sizes of modules carrying information in the symbol. Methods are described for identifying the location and size of detection patterns in images of the symbol and for locating modules in the symbol to facilitate extraction of information carried by the modules.

  • Patent number: 8181878
    Abstract: A method and apparatus for indicating an in-focus or an out-of-focus condition for an imaging device (1, 2) in an optical reading and decoding apparatus (20) for receiving a coded image from a target area (29) on an article or package. In the method of the invention, two beams of light (27, 28) are generated to provide two illuminated aiming marks (32, 33) on the target. An in-focus condition is indicated when the two aiming marks are in a pre-defined spatial relationship relative to each other on the target. The in-focus condition or an out-of-focus condition can be signaled by controlling attributes of aiming marks (32, 33) or by controlling attributes of status indicator LEDs (12) on the apparatus (20) or by controlling an audible sound.
