  • Patent number: 11531825
    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.

  • Publication number: 20220383010
    Abstract: Embodiments of the present disclosure provide an alternative illuminator assembly and corresponding imaging assemblies utilizing the alternative illuminator assembly. The alternative illuminator assembly may provide alternative illuminations from those produced by an imager engine, such that the alternative illuminations may provide specific illuminations at specific illumination angles to illuminate a field of view for a desired purpose. In an example context, the alternative illuminator assembly provides one or more alternative illuminations for improving the likelihood of successfully reading specific direct part marking indicias of various types. Embodiments are provided using overlapping subassemblies that enable a small form factor assembly that can fit into mobile apparatus chasses, for example within conventional cell phone housings of around 7 millimeters.

  • Publication number: 20220303451
    Abstract: Embodiments of the disclosure relate generally to automatic focus selection in a multi-imager environment. Embodiments include methods, systems, and apparatuses configured for capturing by a first image sensor, a first image of a visual object with a background associated with a subject. A characteristic difference between the visual object in the first image and the background in the first image is determined and a distance determination mode is selected based on the determined characteristic difference. Accordingly, a distance to the subject is calculated based on the selected distance determination mode and a second image sensor is controlled to capture a second image of the subject, based on the calculated distance to the subject.

  • Patent number: 11450083
    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.
