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.
Abstract:
Systems for power management of a fleet of devices through information storage sharing are described. According to one embodiment, each one of a group of networked devices offloads information to a substantially powered hub device before entering a low power consumption mode and receives the respective information back from the hub device upon wake. Another embodiment describes a system of networked devices in which each one of the networked devices offloads information to a selected networked device before entering a sleep mode and receives the respective information back from that selected networked device after entering a wake mode. Another embodiment describes a system whereby the original selected networked device then backups to a new selected networked device if the original selected networked device needs to enter a low power consumption mode, and the other networked devices receive the respective information back from the new selected networked device.
Abstract:
A system and method of determining if a surface contains print or is a screen of a mobile device is provided. The method is comprised of the steps of: acquiring a spectral wavelength signature of the surface; comparing the spectral wavelength signature of the surface to RGB triple-peak emission spectra; scanning the surface with an image-based scanner in non-illumination mode based upon the spectral wavelength signature of the surface corresponding to the RGB triple-peak emission spectra, and scanning the surface with an image-based scanner in illumination mode based upon the spectral wavelength signature of the surface not corresponding to the RGB triple-peak emission spectra.

Abstract:
Point-of sale (POS) devices and checkout devices are provided. An exemplary checkout apparatus includes a plurality of sensing elements arranged in fixed relationship with each other at the mouth of a bag. At least one of the sensing elements senses a code arranged on a product as the product is being placed into the bag.
Abstract:
A flexible scan element for a laser scanner is disclosed. The flexible can element may be made from a non-linear elastomeric material that twists sufficiently for scan operation but resists unwanted motion from shock/vibration through the use of a rigid motion-limiting member encapsulated, at least partially, within the body of the flexible scan element. In this way, no external components are required for limiting excess motion.
Abstract:
A method for determining the dimensions of an object comprises projecting a laser pattern (e.g., a visible laser pattern) onto an object, capturing an image of the projected pattern on the object, and determining the dimensions of the object based, at least in part, on the captured image. An exemplary method includes projecting a laser pattern (e.g., a grid or a set of lines) onto a rectangular box. Typically, the box is positioned such that two non-parallel faces are visible to the system or device projecting the laser pattern and a camera system with known field of view characteristics. The camera system is used to capture an image of the laser light reflecting off of the box.
Abstract:
Embodiments provide apparatuses, computer-implemented methods, and computer program products for generating an augmented aimer and using the augmented aimer to generate an augmented image. The augmented image is usable to aim a device, such as a reader, that captures image(s) for processing to detect and/or decode machine-readable symbologies therein. Some example embodiments include improved reader(s) configured to generate and/or utilize the augmented aimer. Some embodiments include receiving a first image captured by a first imager of at least one imager. Some embodiments further include generating, utilizing the first image, an augmented image comprising an augmented aimer corresponding to an optical center point associated with the first imager. Some embodiments further include causing rendering of the augmented image to at least one user interface. Some embodiments further include processing the first image to attempt reading of at least one machine-readable symbology in the first image.
Abstract:
Embodiments of the disclosure relate generally to illumination synchronization in a multi-imager environment. Embodiments include systems, methods, computer program products, and apparatuses configured for operating a near-field illumination source associated with a near-field image sensor, based on a first illumination pulse train. An exposure period of a far-field image sensor is determined and one or more characteristics of the first illumination pulse train are modified to accommodate the exposure period of the far-field image sensor.
Abstract:
Optical assembly, imaging reader, and method for dual-lens illumination are provided. For example, an example optical assembly may include first and second light sources, first and second collection lenses positioned and shaped to collect light emitted by the first and second light sources and transmit the collected light with reduced divergence, first and second pattern-shaping apertures positioned to allow at least a portion of the light transmitted by the first and second collection lens to pass therethrough, and first and second projection lens positioned to receive the light transmitted by the first and second collection lenses and passed through the first and second pattern-shaping apertures. The projection lenses are shaped to project the received light into the field of view of an imaging system with a higher intensity at a lateral side edge of the light projected and a lower intensity at a medial side edge of the light projected.
