  • Patent number: 10733748
    Abstract: An optical dimensioning system includes light emitting assemblies configured to project a predetermined pattern on an object. The optical dimensioning system further includes an imaging assembly configured to sense light scattered and/or reflected of the object, and to capture an image of the object while the pattern is projected. A processing assembly, in the optical dimensioning system, is configured to analyze the image of the object to determine one or more dimension parameters of the object.

  • 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.

  • Publication number: 20190026912
    Abstract: An optical dimensioning system includes one or more light emitting assemblies configured to project a predetermined pattern on an object; an imaging assembly configured to sense light scattered and/or reflected of the object, and to capture an image of the object while the pattern is projected; and a processing assembly configured to analyze the image of the object to determine one or more dimension parameters of the object. A method for optical dimensioning includes illuminating an object with at least two identical patterns; capturing at least one image of the illuminated object; and calculating dimensions of the object by analyzing pattern separation of the elements comprising the projected patterns. The patterns can be produced by one or more pattern generators.

  • 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.

  • Patent number: 10055627
    Abstract: Performance and size improvements in indicia readers are disclosed. The improvements provide for the integration of a barcode image scanner in a size restricted mobile computer device, such as a slim mobile data terminal or a smart mobile phone, and provide for the ability for the indicia reader to read direct product marking (DPM) type of barcodes. The improvements include the incorporation of an illumination module or bar that can generate dark field and bright field illumination. The illumination module can be designed to match the front end of a smart mobile phone and maintain a low profile design. Symmetric arranged multi-field, multi-color illuminator with close-up corrective lens and near coaxial aimer optics provide illumination and aiming support for the DPM scanning. The improvements allow the indicia reader, assembled in a slim mobile data terminal, to read direct product marking (DPM) type of barcodes.

  • Patent number: 9955099
    Abstract: A CMOS image sensor for a camera assembly is provided, having a sensor die with opposing faces, an upper face, and a lower face. On the upper face, the sensor die is provided with a sensor array, an analog-to-digital conversion module, a digital logic circuit, and a timing and clock control circuit. The sensor array is substantially centered on the sensor die. The analog-to-digital conversion module is split into two submodules. Each submodule is disposed adjacent to the sensor array and positioned on opposing sides of the sensor array. The digital logic circuit forms a first row. The timing and clock control circuit and the analog signal processing circuit are adjacent and form a second row. The first and second rows have similar dimensions and are disposed on opposite sides of the sensor array.
