  • Publication number: 20210097320
    Abstract: An optical dimensioning system includes one or more light emitting assemblies configured to project one or more predetermined patterns on an object; an imaging assembly configured to sense light scattered and/or reflected off the object, and to capture an image of the object while the patterns are projected; and a processing assembly configured to analyze the image of the object to determine one or more dimension parameters of the object. The light emitting assembly may include a single piece optical component configured for producing a first pattern and second pattern. The patterns may be distinguishable based on directional filtering, feature detection, feature shift detection, or the like. A method for optical dimensioning includes illuminating an object with at least two detectable patterns; and calculating dimensions of the object by analyzing pattern separate of the elements comprising the projected patterns. One or more pattern generators may produce the patterns.

  • Publication number: 20200387681
    Abstract: An indicia-reading module is capable of integration into the smallest face of thin-profile smart device. The module employs chip-on-board packaging and a customized sensor enclosure to eliminate the stack-up height found in conventional packaging. The module also employs a customized frame to reduce volume by integrating circuit subassembly circuit boards into a unique architecture and by serving as the lenses for the illuminator and the aimer, thereby eliminating the need for any extra lenses or holders.

  • Patent number: 10311274
    Abstract: The present invention embraces an optical indicia reader, e.g., barcode scanner, that captures images of optical indicia under multiple imaging conditions within the span of a single frame. The reader includes an image sensor having selectively-addressable pixels that can be divided into groups having regions of interest (ROIs) within the reader field of view. Each pixel group is shuttered separately to obtain independent partial frame images under separate imaging conditions.

  • Patent number: 10303909
    Abstract: An add-on device for an image scanner for scanning barcodes is provided. The add-on device includes a housing mounted to the standard range lens front on an image scanner, and a lens holder. The lens holder has a first position for holding a first lens, a second position being an aperture, and a third position for holding a second lens. A high-density lens is mounted in the first position. An extended range lens is mounted in the third position. The lens holder is mounted in the housing and is transverse to the optical axis of the standard range lens of the image scanner. Further, the lens holder is movable within the housing in order to alternately position the high-density lens, the aperture, and the extended range lens to be in alignment with the optical axis of the standard range lens of the image scanner.

  • Patent number: 10158612
    Abstract: A system and method for secure data transfer between two secure computer systems via display-based transfer in geometric form. A first computer network stores alphanumeric data. The alphanumeric data is encoded into a geometric data form, such as a bar code or matrix code representation or other non-text, non-numeric data form suitable for visual display. The bar code or matrix code, or other geometric data form, is displayed on a display monitor connected to the first computer network. The system and method then receives the displayed geometric data form on a second computer network. The second computer network has a camera which obtains a view of the bar code, matrix code, or other geometric data representation. The second computer network then decodes the geometric data representation to restore the data to its native form (such as text or numbers). The second computer network then stores the retrieved data.
