  • Patent number: 11743592
    Abstract: Systems and methods for fast autotuning of industrial fixed vision cameras are disclosed herein. An example method includes modifying illumination settings of a camera until a brightness value for captured image data reaches a minimum value; modifying a focus level of the camera to determine a range of camera focus levels for successfully decoding barcodes; configuring the camera to operate using a midpoint focus value of the range; modifying illumination settings of the camera until the brightness associated with the captured image data reaches an optimal value; and modifying the focus level of the camera, within the range, to determine an optimal focus level at which sharpness for the captured image is optimized; and capturing, by the camera, operating at the determined optimal focus level and with illumination settings for the optimal threshold brightness value, image data associated with a new target object affixed with a new barcode.

  • Patent number: 11743748
    Abstract: A computing device includes: a wireless communication interface; and a processor configured to: establish a connection with a wireless network; while a network-layer status of the connection is active, monitor attributes of the connection at the wireless communication interface, the attributes including (i) a number of uplink packets transmitted since a most recent downlink packet was received, and (ii) a time period elapsed since the most recent downlink packet was received; determine that the attributes meet recovery criteria indicative of a network-layer interruption in the wireless network; in response to the determination, control the wireless communication interface to initiate a recovery action to resolve the network-layer interruption.

  • Patent number: 11734529
    Abstract: An optical assembly for illuminating at least one object appearing in a field of view (FOV). The optical assembly includes first and second illumination sources configured to provide first and second illumination to illuminate a target of the object. An aperture configured to collimate the first and second illumination and to provide the illumination to a dual collimator. The dual collimator is disposed to collimate the first and second illumination and to provide the first and second illumination to a dual microlens lens array (MLA).

  • Patent number: 11734528
    Abstract: An imaging device includes a housing having an optically transmissive window, a first imaging assembly, a second imaging assembly, and illumination emitter for generating a user interface visual indicator. The illumination emitter may be a light emitting diode or other light source. To prevent internal reflection of the user interface visual indicator off the window and appearing in captured images from the imaging assemblies, the imaging device synchronizes emitter-on times and sensor exposure-on times to prevent substantial overlap therebetween, thereby allowing for more accurate image captures, including color image captures of the imaging device.

  • Patent number: 11734530
    Abstract: Systems and methods are described for implementing scanner configuration based on focus of one or more host application screens. Example systems and methods comprise detecting a focus event of an application (app) as executing on one or more processors. An active focus module (AFM) detects the focus event. The AFM or a scanner device is configured to receive data in a first data app format. Scan data is scanned by the scanner device and is formatted, at the AFM or at the scanner device, into app data having the data app format. The app data is then provided to the app.

  • Patent number: 11727664
    Abstract: Systems and methods for adaptively determining a region of interest (ROI) are disclosed herein. An example device includes an imaging assembly and a controller. The imaging assembly captures image data comprising pixel data from a plurality of pixels. The controller calculates a contrast value for each pixel of the plurality of pixels, generates a histogram of contrast values, calculates an area under the curve of the histogram, and determines a contrast value threshold to delineate between high-contrast value pixels and low-contrast value pixels. The controller also identifies a ROI within the image data by locating a region within the image data that (i) satisfies a pre-determined size threshold and (ii) contains a largest number of high-contrast value pixels relative to all other regions that satisfy the pre-determined size threshold, and adjusts imaging parameters of the imaging assembly based on the ROI to capture at least one subsequent image.

  • Patent number: 11727229
    Abstract: A method and system for operating an indicia reader are disclosed herein. An example method includes detecting a first object in the scanning region; capturing one or more images of the first object to create first image data; determining that a successful decode of an indicia has not occurred; retrieving the first image data of the first object; generating, using the first image data, an embedding of the first image data; detecting a second object in the scanning region; retrieving one or more support samples from an image database; comparing the embedding of the image data to each support sample of the one or more support samples; based on the comparison that the embedding of the image data does not match any support sample, performing an operation.
