    Abstract: The present disclosure provides an indicia decoding device with a printed circuit board (PCB) that allows signals from internal imaging assemblies to pass through a sealed cavity boundary to an external host. This device comprises a decode module, an upright and horizontally mounted window, and multiple imaging assemblies housed within a sealed cavity. The PCB is partially located inside and outside the cavity, featuring ports inside and outside the sealed cavity. Signals from secondary imaging assemblies bypass the decode module, utilizing electrically conductive paths on the PCB, ensuring signal integrity without modification. The PCB may also include image processing circuitry, with results transmitted to the host.

    Abstract: An imaging engine including a telephoto lens for compact long range barcode readers is disclosed herein. An example imaging engine includes an imaging sensor and a telephoto lens assembly. The example telephoto lens assembly includes a first lens, disposed along an optical axis; a second lens, disposed along the optical axis to correct for pupil aberrations of the image projected after a fourth lens onto the imaging sensor; a third lens, disposed along the optical axis to correct for chromatic aberration of the image projected after the fourth lens onto the imaging sensor; and the fourth lens, disposed along the optical axis to correct for optical field curvature of the image projected after the fourth lens onto the imaging sensor.

    Abstract: Concepts described herein described herein relate to the determination of media that is presented to indicia readers for digital reading of said indicia. In some cases, embodiments described herein rely on operating an imaging reader in a particular mode of operation where image frames are captured with the intensity of the illumination light varying during said capture and subsequently determining, by analyzing those frame, a media type appearing within the FOV based on one of (i) a lack of an optical signature associated with varying the intensity of the illumination light during the capture of the frame or (ii) a presence of the optical signature associated with the varying the intensity of the illumination light during the capture of the frame.

    Abstract: Methods, systems, and devices for locating and tracking an object in a machine vision field of view based upon an affixed indicium visible in an indicium decoding field of view are provided herein. An example method for object tracking includes receiving, from a first optical imaging assembly having a first field of view (FOV), a first image captured over the first FOV, receiving, from a second optical imaging assembly having a second FOV, a second image captured over the second FOV, decoding an indicium in the first image, detecting at least a portion of the indicium in the second image, and identifying an object of interest associated with the indicium in the second image based upon a location of the at least the portion of the indicium in the second image.

    Abstract: An imaging system includes a first imager, a second imager, and an aiming assembly. The aiming assembly is configured to selectively output light having at least one of a first pattern or a second pattern, where the light having the first pattern intersects a first imaging axis of the first imager and the light having the second pattern intersects a second imaging axis of the second imager. The aiming assembly defines a first light pathway that is common to the light for the first pattern and the second pattern and defines second and third light pathways. The light travels from the first light pathway along the second light pathway to selectively output the first pattern and travels from the first light pathway along the third light pathway to selectively output the second pattern.

    Abstract: A method includes: capturing an image; partitioning the image into sub-images; for each sub-image: providing the sub-image to a detection model, receiving, from the detection model, one or more sub-image regions of interest (SROIs), each SROI defined by (i) a position of the SROI, and (ii) one of a set of symbology categories, each symbology category encompassing a plurality of barcode symbologies; generating one or more regions of interest (ROI) from the SROIs, each ROI defined by a position of the ROI in the image, and a symbology category; and providing the ROIs to a decoder.
