Abstract: Devices and systems for modifying feedback in response to a successful indicia decode are disclosed herein. An example device includes an imaging sensor configured to capture image data, and an indicia decoder communicatively coupled with the imaging sensor that is configured to decode an indicia from the image data. The example device further includes one or more processors configured to: determine an ambient lighting condition based on at least a portion of at least one image frame captured as part of the image data; determine, based on the ambient lighting condition, whether to cause the imaging device to output a first feedback response or a second feedback response in response to a successful indicia decode; and responsive to receiving a successful indicia decode indication from the indicia decoder, cause the imaging device to output the first feedback response or the second feedback response.

Abstract: Methods and apparatus for providing out-of-range indications are disclosed. An example imaging reader includes an image sensor and an optical assembly. The imaging reader may include a distance determining module configured to determine a distance to a target. The imaging reader may include an indication determining module configured to determine an out-of-range indication when the distance satisfies a first condition. An indicator may be included and configured to present the out-of-range indication. The image sensor may be configured to capture a representation of an image of the target when the distance satisfies a second condition. The imaging reader may include an indicia decoder configured to decode an indicia in the representation to determine an indicia payload and/or a communication interface to convey the indicia payload to a host system.

Abstract: A method includes: capturing, by a scanner device comprising an image sensor, first image data representing at least a portion of a first item; detecting, by the scanner device, a first barcode represented in the first image data; decoding the first barcode to determine first identifier data for the first item; performing a lookup using the first identifier data to determine a first entry for the first item stored in a data store; generating a sub-image representing a region-of-interest of the first item; generating, using an image encoder, a first vector representation of the sub-image; comparing the first vector representation of the sub-image to at least one second vector representation stored in the data store in association with the first entry; and generating first data indicating that the first barcode is matched with the first item.

Abstract: Barcode readers with transflective mirrors are disclosed herein. An example barcode reader includes a housing and a window positioned within the housing, an imaging sensor and second imaging sensor positioned within the housing, and a transflective mirror positioned within the housing and in a path of a field-of-view of the imaging sensor. The field-of-view of the imaging sensor passes through the transflective mirror and out the window with the transflective mirror in a transmissive state and the field-of-view of the second imaging sensor is reflected off of the transflective mirror and out the window with the transflective mirror in a reflective state.

Abstract: A method is disclosed for adjusting imaging parameters of a bioptic barcode reader. The method includes capturing, by an imaging assembly, an initial image of a target object having an indicia thereon. The imaging assembly captures the initial image according to an initial imaging parameter. The method further includes attempting to decode the indicia from the initial image, and responsive to being unable to decode the indicia, detecting a substantially static presence of the target object within a field of view (FOV) of the imaging assembly. The method then includes, responsive to detecting the substantially static presence of the target object within the FOV, adjusting the initial imaging parameter to a subsequent imaging parameter, wherein the subsequent imaging parameter is different than the initial imaging parameter.

Abstract: An imaging reader includes a light source generating an illumination beam over a working distance, and a variable focus imaging assembly with an image sensor, a variable focus optical element, a variable focus imaging controller that controls operation of the variable focus optical element to define a plurality of imaging planes over the working distance. The variable focus imaging controller assesses a variety of scanning parameters and determines the number of imaging planes over the working distance and the distance of each of imaging plane from the image sensor, to allow the imaging reader to capture images of a target object only at each of the imaging planes, thereby avoiding time-consuming autofocusing on the target. The imaging reader captures images in a sequential order greatly reducing image capture and image analysis processing time.

Abstract: Methods and apparatus for configuring reduced decode ranges for barcode scanners are disclosed. An example method includes determining a closest focus distance of a plurality of focus distances at which a barcode placed at a furthest limit of a reduced decode range can be successfully decoded; determining a furthest focus distance of the plurality of focus distances at which the barcode placed at a closest limit of the reduced decode range can be successfully decoded; determining a subset of the plurality of focus distances that consists of the closest focus distance, the furthest focus distance, and focus distances between the closest focus distance and the farthest focus distance; and configuring the barcode scanner to only use the subset of focus distances during subsequent attempts to decode barcodes.

Abstract: Barcode readers with transflective mirrors are disclosed herein. An example barcode reader includes a housing and a window positioned within the housing, an imaging sensor and an illumination source positioned within the housing, and a transflective mirror positioned within the housing. The field-of-view of the imaging sensor is directed through the window along a first central axis of the field-of-view of the imaging sensor and the illumination pattern from the illumination source is directed through the window along a second central axis of the illumination pattern that is substantially parallel to the first central axis of the field-of-view of the imaging sensor.

Abstract: A barcode reader includes an illumination assembly configured to illuminate a target; an imaging assembly configured to capture an image of the target, and a visual indicator assembly that includes: a projection lens; a first light source configured to emit first color light through the projection lens to project an aim pattern onto the target; a second light source configured to emit second color light through the projection lens to project a visual indicator onto the target; and an optical element configured to direct the light from both the first light source and the second light source to the projection lens. A memory and a processor of the barcode reader are configured to cause the first light source to emit light prior to the imaging assembly capturing the image; and cause the second light source to emit light subsequent to the processor successfully decoding a symbology in the captured image.
