Abstract: Methods for optimizing improper product barcode detection are disclosed herein. An example method, includes analyzing an object-based identification data against an indicia-based identification data to determine if there is a match. Responsive to there not being a match, entering a release condition state, where, instead of automatically sending a failed match signal to a symbology reader, a remote server awaits satisfaction of the release condition, before sending to the symbology reader. In some examples, a release condition is automatically satisfied by identifying a match in a subsequent comparison. In some examples, a user of the remote server is to satisfy the release condition.

Abstract: Embodiments of the present disclosure are directed to wakeup systems for indicia readers. In an example embodiment, the present invention leverages data sensed through a horizontal window of a bioptic barcode reader to switch from a sleep mode to a read mode. In particular, the sensed data may be used exclusively or as a determinative factor for waking up the barcode reader.

Abstract: A method of auxiliary data capture control includes: storing, at a data capture device, a trigger condition and a baseline value captured by a sensor; controlling the sensor to obtain captured data; determining, based on the captured data and the baseline value, whether the trigger condition is satisfied, wherein the trigger condition includes whether the captured data exceeds the baseline value; and when the trigger condition is satisfied, controlling an auxiliary data capture sensor to obtain auxiliary captured data.

Abstract: Methods of detecting scan avoidance events during decode sessions are disclosed herein. An example method includes during a timeout period at one or more processors of the symbology scanner, identifying and decoding a transaction affecting indicia on an object in one or more images to obtain a transaction affecting payload; during the timeout period at the one or more processors, identifying one or more visual features in the one or more images; and in response to identifying a non-transaction affecting indicia associated with the one or more visual features, and failing to identify or decode the transaction affecting indicia, determining a potential scan avoidance attempt and generating a scan avoidance alarm signal.

Abstract: Methods of detecting scan avoidance events when items are passed through a field of view (FOV) of a scanner are disclosed herein. An example method, during a decode session, receiving, at one or more processors of the symbology reader, an image of an object; during a timeout period, detecting, at the one or more processors, an indicia in the image of the object, the indicia having a decodable payload; during the timeout period, attempting to decode the indicia to identify the decodable payload, at the one or more processors; and after the timeout period expires, when at least one portion but less than all portions of the indicia is decodable, determining a potential scan avoidance attempt and generating a scan avoidance alarm signal.

Abstract: Methods of detecting scan avoidance events are disclosed herein. An example method includes measuring, by a weighing scale associated with a barcode reader, an unstable weight over a timeframe having a duration that is greater than a threshold duration. The method further includes monitoring for (i) the barcode reader's failure, during the first timeframe, to transition from a first state in which an imager of the barcode reader does not transmit images for decoding to a second state in which the imager captures images over an FOV including a product scanning region and transmits the captured images for decoding; or (ii) the barcode reader's failure to decode a barcode from images captured over the FOV including the product scanning region during the first timeframe; and generating an alert indicating a potential scan avoidance event responsive to both the measured unstable weight over the timeframe and one of (i) or (ii).

Abstract: Methods for accurate object tracking are disclosed herein. An example the method includes receiving, from a first optical imaging assembly having a first field of view (FOV), a first image captured over the first FOV and based on a decode of an indicia associated with an object of interest, identifying the object of interest within the first image. The method further includes determining a location of the object of interest within the first image and mapping the location of the object of interest within the first image to a predicted location of the object of interest within a second image, the second image being received from a second optical imaging assembly having a second FOV and the second image being captured over the second FOV.
