  • Patent number: 10282721
    Abstract: A system for verifying a price associated with an item in a retail environment includes a price tag having an optical member that includes an optical characteristic that modifies an amount of optical energy that leaves the optical member relative to an amount of optical energy received by the optical member, and a price tag holder including an optical sensor having an emitter and a detector. The emitter is positioned to emit optical energy onto the optical member and the detector is positioned to receive optical energy leaving the optical member. A computing device in operable communication with the optical sensor is operative to determine whether the price tag is accurate based upon a comparison between the amount of optical energy received by the detector and the amount of optical energy emitted by the emitter.

  • Patent number: 10244180
    Abstract: An imaging reader has near and far imagers for imaging illuminated targets to be read over a range of working distances. A range finder determines a distance to a target. A default imager captures a minor portion of an image of the target, and rapidly determines its light intensity level. At least one of the imagers is selected based on the determined distance and/or the determined light intensity level. The exposure and/or gain of the selected imager is set to a predetermined value, and an illumination level is determined, also based on the determined light intensity level and/or the determined distance. The selected imager, which has been set with the predetermined value, captures an image of the target, which has been illuminated at the illumination light level.

  • Patent number: 10216840
    Abstract: Various of the disclosed embodiments concern computer systems, methods, and programs for extracting information from an asset tag that can be used to monitor the corresponding asset. An operator, e.g., employee of an enterprise, logs into an application executed by a mobile device that includes a camera. A tag template can then be manually selected by the operator or automatically selected by the application. The tag template is used during scanning to locate and identify machine-readable elements, human-readable elements, structural elements, or some combination thereof. Once the application registers a successful scan of the asset tag, the operator can review and confirm the information was extracted correctly. Generally, the extracted information is transmitted to an asset management system, which creates a database entry that allows the asset to be continually monitored by the enterprise, e.g., each time the asset tag is subsequently scanned.

  • Patent number: 10158777
    Abstract: An image processing apparatus includes a memory, a correction circuit, and a calculation circuit. The memory stores image data of an original image that is moved in a sub-scanning direction with respect to an image sensor. The correction circuit sequentially reads the image data from the memory line by line in the main scanning direction, extracts a pixel in a position corresponding to the inclination, and forms an inclination-corrected line in the main scanning direction to correct the inclination. The calculation circuit calculates an amount of movement of a corner of the original image with respect to the sub-scanning direction before and after correction of inclination of the original image with respect to a main scanning direction. The correction circuit restricts progress of formation of the inclination-corrected line based on the amount of movement. The amount of movement is applied when the inclination of the original image is corrected.

  • Patent number: 10096500
    Abstract: The present invention discloses apparatuses and methods for simultaneous viewing and reading top and bottom images from a workpiece. The present ID reader can comprise an enclosure covering a top and bottom section of the workpiece with optical elements to guide the light from the workpiece images to a camera. The optical element can be disposed to receive images from a high angle with respect to the surface of the workpiece. The present ID reader can further comprise a light source assembly to illuminate the image. The light source assembly can utilize a coaxial light path with the images, preferably for bright field illumination. The light source assembly can also utilize a non-coaxial light path, preferably for dark field illumination.

  • Patent number: 10096218
    Abstract: An RFID/object recognition system monitors the passage of an object through a portal into a space. An RFID reader adjacent the portal communicates with an RFID tag within a preselected distance from the RFID reader. A data processor processes data from the RFID reader. A 3-dimensional scanner has an RGB camera and a depth sensor with an infrared laser projector and a monochrome CMOS sensor. An infrared laser controller is electronically coupled with the infrared laser projector, and a monochrome CMOS processor is electronically coupled with the monochrome CMOS sensor. The infrared laser controller, monochrome CMOS processor, and RGB camera are electronically coupled with a processor. The RFID reader receives data from an RFID tag when an RFID-tagged object passes within the preselected distance from the RFID reader through the portal. The 3-dimensional object recognition assembly identifies where the RFID-tagged object is located within the defined space.

    Abstract: Apparatus for generating a dynamic structured light pattern for optical tracking in three-dimensional space, comprises an array of lasers, such as a VCSEL laser array, to project light in a pattern into a three-dimensional space; and an optical element or elements arranged in cells. The cells are aligned with subsets of the laser array, and each cell individually applies a modulation, in particular an intensity modulation, to light from the laser or lasers of the subset, to provide a distinguishable and separately controllable part of the dynamic structured light pattern. A method of generating a structured light pattern is disclosed, in which light is provided from an array of lasers, and light is individually projected from subsets of the array of lasers to provide differentiated parts of the structured light pattern.

  • Patent number: 10074228
    Abstract: This invention proposes a per-piece unique optical randomness on security labels that enables a unique color profiling. Verification of Color-profiling is fully automated. Color profiling is captured under a light homogenizer. Color profiling starts at certain intersection point (within security label) of line joining reference circle to centre of security label. To detect duplication, multiple color-profiles are acquired with scanner flash light switched-on & switched-off. Even if same label is reapplied after tampering the asset the color profiling gets auto changed and can be automatically verified. Color profiling based security is layered on fundamental layer of spatial orientation. Also optically variable region can be leveraged to quickly verify if label is original without matching with stored color profile in cloud during registration scan.
