Abstract: A barcode reader configured to capture interleaved frame types optimized for vision capture and barcode capture are disclosed herein. An example barcode reader is configured to operate in a pre-determined repetitive pattern of capturing a first frame and capturing a second frame over a reading cycle having a fixed duration after a triggering event, wherein the first frame is captured over a first exposure period having a first duration, and the second frame is captured over a second exposure period having a second duration, and wherein the first frame is associated with a first brightness parameter, and the second frame is associated with a second brightness parameter.

Abstract: A bioptic barcode reader is disclosed for selective use of illumination color to capture appropriate data. The bioptic barcode reader includes a housing and a primary imager positioned within the housing, configured to scan a target object during a first time period. The bioptic barcode reader further includes a primary illumination source positioned within the housing configured to emit primary illumination in a primary wavelength range during the first time period. The bioptic barcode reader further includes a secondary imager configured to capture one or more images of a target object during a second time period. The bioptic barcode reader further includes a secondary illumination source configured to emit secondary illumination in a secondary wavelength range during the second time period, wherein the second time period and first time period are interleaved and the secondary wavelength range is different from the primary wavelength range.

Abstract: A barcode reader has a weigh platter and an off-platter detection assembly. The weigh platter is configured to measure a weight of an object and has a surface extending in a first transverse plane, a proximal edge, a first lateral edge extending non-parallel to the proximal edge, and a distal edge. The off-platter detection assembly includes a light emission assembly and a light detection assembly. The light emission assembly is configured to emit a collimated light beam along the first lateral edge, above the surface. The light diffusing barrier is positioned in a path of the collimated light beam and is configured to diffuse the light beam such that the light diffusing barrier appears to be illuminated when contacted by the light beam and appears not to be illuminated when not contacted by the light beam.

Abstract: Multiple field of view (FOV) systems are disclosed herein. An example system includes a bioptic barcode reader having a target imaging region. The bioptic barcode reader includes at least one imager having a first FOV and a second FOV and is configured to capture an image of a target object from each FOV. The example system includes one or more processors configured to receive the images and a trained object recognition model stored in memory communicatively coupled to the one or more processors. The memory includes instructions that, when executed, cause the one or more processors to analyze the images to identify at least a portion of a barcode and one or more features associated with the target object. The instructions further cause the one or more processors to determine a target object identification probability and to determine whether a predicted product identifies the target object.

Abstract: A bioptic reader assembly includes a scale assembly, bioptic barcode reader, and video upgrade module. The scale assembly includes a support frame and a platter and has a width that is less than or equal to 11½ inches. The bioptic barcode reader is mounted to the support frame and includes a lower housing portion positioned below the platter, an upper housing portion extending above the lower housing portion and the platter, and a camera. The video upgrade module is operatively connected to the bioptic barcode reader, is in communication with the camera, and is configured to process and interpret images received from the camera. The video upgrade module is positioned within the width of the scale assembly and within a height defined from a top surface of the platter to a bottom of the lower housing portion, which is preferably less than or equal to 4 inches.

Abstract: A modular off-platter detection assembly for use with a barcode reader includes a housing, a first light source, a first light sensor, and a controller operatively coupled to the first light source and the first light sensor. The housing is configured to be removably mounted to the barcode reader, a frame supporting the barcode reader, or the workstation. The first light source is positioned within the housing and emits a first light along a first lateral edge of a weigh platter. The first light sensor is positioned within the housing, has a first field-of-view along the first lateral edge, and is configured to detect at least a portion of the first light reflected towards the housing. The controller is configured to provide a first alert in response to receipt of a first value from the first light sensor indicating there is an object extending across the first lateral edge.

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.
