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: 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: Systems for alternative illumination in global shutter barcode readers are disclosed herein. An example system includes an imaging apparatus configured to capture an image during an image capture period, and an imaging shutter configured to actuate and expose the imaging apparatus to an external environment during the image capture period. The example system also includes an illumination light emitting diode (LED) configured to emit illumination, and an illumination drive circuit configured to cause the illumination LED to emit the illumination (i) during the image capture period and (ii) when the imaging apparatus is shielded from exposure to the external environment by the imaging shutter.

Abstract: Barcode readers and methods for directing fields-of-view of imaging sensors of barcode readers are disclosed herein. An example barcode reader includes a housing, an 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 transflective mirror reflects at least a first portion of the field-of-view of the imaging sensor in a first direction with the transflective mirror in a reflective state and allows the field-of-view of the imaging sensor to pass through and continue in a second direction, different than the first direction, with the transflective mirror in a transmissive state.

Abstract: Methods and systems for tracking focus of an adjustable variable focus lens-based imaging system are disclosed. An example method includes identifying an initial focus position of an adjustable variable focus lens assembly and determining focusing parameters corresponding to that focus position. The focusing parameters are compared to a lens behavior model and a new, compensated focus position of the lens assembly is determined correcting for changes in lens assembly performance. A small window focusing sweep range, between forward and aft positions, may also be adjusted based on the lens behavior model to better identify the compensated focus position.

Abstract: Systems and methods for anonymizing image data are disclosed herein. An example implementation includes: capturing, with an indicia reader, an image data of a field of view (FOV) associated with an imager within the indicia reader; determining, with the indicia reader, a facial area within the image data; producing, with the indicia reader, an anonymized image data by altering pixel data of the facial area of the image data; and (i) storing the anonymized image data in a nonvolatile memory of the indicia reader, or (ii) transmitting the anonymized image data from the indicia reader to one or more host processors.

Abstract: Methods and systems to implement a miniature long range imaging engine with auto-focus, auto-zoom, and auto-illumination are disclosed herein. An example method includes detecting, by a microprocessor, a presence of an aim light pattern within the FOV; determining, by the microprocessor and in response to the detecting, a target distance of an object in the FOV based on a position of the aim light pattern in the FOV, the target distance being a distance from the imaging engine to the object; causing, by the microprocessor, a variable focus optical element to focus on the object based on the target distance; and responsive to making a first determination, by the microprocessor, selecting, based on the target distance, one of a plurality of zoom operation modes.

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.
