Abstract: A barcode reader having lower and upper housings, a weigh platter in the lower housing, and an off-platter detection assembly. The weigh platter has a proximal edge adjacent the upper housing, a first lateral edge, and a distal edge. The off-platter detection assembly comprises an off-platter indication system having a plurality of linearly aligned light sources, each light source representing a location along the first lateral edge, and controller operatively coupled to the plurality of light sources. The controller is configured to: determine if an object extends over the first lateral edge; determine a location of the object along the first lateral edge; and illuminate a first portion of the light sources representing a distance between the proximal edge of the weigh platter and the object and de-illuminate a second portion of the light sources representing a distance between the object and the distal edge of the weigh platter.

Abstract: Example methods and apparatuses to mitigate specular reflections and direct illumination interference in bioptic barcode readers are disclosed. An example method includes creating a first sub-field of view passing through a first window, creating a second sub-field of view passing through a second window, while activating a first illumination source to illuminate the first sub-field of view and deactivating a second illumination source associated with the second sub-field of view, capturing first images of the first sub-field of view, while activating the second illumination source to illuminate the second sub-field of view and deactivating the first illumination source, capturing second images of the second sub-field of view, and attempting to decode a barcode within at least one of the first images and the second images.

Abstract: A system and methods for implementing a transflective mirror as a rolling shutter sensor. The method includes. The method includes a controller setting a current state of an obfuscator to a transmissive state at a first point in time, the first point in time being a time when all pixels of an imaging sensor are in an active state. An imaging sensor then obtains an image of an object in a field of view of the imaging sensor. The image is obtained at a time when the obfuscator is in the transmissive state. The controller then sets the current state of the obfuscator to an obfuscative state at a point in time before a single pixel of the plurality of pixels is switched to an inactive state, wherein the active state of a pixel is a state in which a pixel is an active optical detector, and the inactive state is a state in which a pixel is not an active optical detector.

Abstract: A weigh platter assembly includes a weigh platter and a parallax based off-platter detection assembly having a light emission assembly, a light detection assembly, and a controller. The light emission assembly has a light source to emit a light beam along a lateral edge of the weigh platter. The light detection assembly detects at least a portion of the light beam reflected from an object extending across the light beam and includes a sensor offset from the light source and an aperture positioned in front of the sensor and configured to limit a field of view of the sensor along the lateral edge between proximal and distal edges of the weigh platter. The controller is configured to provide a first signal in response to a first value received from the sensor and to provide a second signal, different from the first signal, in response to a second value.

Abstract: Methods and systems include using three-dimensional imaging apparatuses to capture three-dimensional images and analyze resulting three-dimensional image data to enhance captured two-dimensional images for scanning related processes such as object identification, symbology detection, object recognition model training, and identifying improper scan attempts or other actions performed by an operator. Imaging systems such as bi-optic readers, handheld scanners, and machine vision systems are described using three-dimensional imaging apparatuses and described capturing three-dimensional images and using with captured two-dimensional images.

Abstract: Techniques for preventing accidental triggers for off-platter detection systems are disclosed herein. An example system includes a weigh platter having a first surface; a scale configured to measure a weight of an object placed on the first surface; an off-platter detection assembly configured to detect an off-platter condition based on a portion of the object resting on a second surface off the weigh platter and/or some portion of the object extending beyond a perimeter of the weigh platter; a processor in communication with the scale and the off-platter detection assembly; and a non-transitory machine-readable storage medium storing instructions that, when executed by the processor, cause the system to generate an alert responsive to at least: (i) the off-platter detection assembly detecting the off-platter condition and (ii) a measurement by the scale of a stable weight greater than a threshold weight, for a time period greater than a threshold time period.

Abstract: Bioptic barcode readers with multiple imaging devices are disclosed herein. An example bioptic barcode reader includes a housing with a generally horizontal window and an upright window, a barcode reading device positioned within the housing, a first imaging device positioned within the housing, and a second imaging device positioned within the housing below the first imaging device. The first imaging device has a first field-of-view directed out of the upright window, the second imaging device has a second field-of-view directed out of the upright window, and a first central imaging axis of the first field-of-view intersects a second central imaging axis of the second field-of-view at an intersecting angle that is greater than or equal to 15 degrees and less than or equal to 55 degrees. The second central imaging axis of the second field-of-view extends upward above the generally horizontal window at a second angle that is greater than 0 degrees.
