Abstract: Example methods and apparatuses to indicate off-platter weigh conditions are disclosed herein. An example barcode reading and weighing apparatus includes a weigh platter; a scale; an off-platter detection assembly configured to detect an off-platter weigh condition; 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 barcode reading and weighing apparatus to, responsive to detecting the off platter condition: compose a weight-conveying message, the weight-conveying message including (i) a weight-conveying field having the weight encoded therein and (ii) overhead information, the overhead information being operative, when the weight-conveying message is received by a POS system, to cause the POS system to not accept the weight for the transaction, the overhead information also not indicating the off-platter weigh condition to the POS system; and send the weight-conveying message to the POS system.

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: A method of auxiliary data capture control includes: storing, at a data capture device, a trigger condition and a baseline infrared value captured by an infrared sensor; controlling the infrared sensor to obtain captured infrared data; determining, based on the captured infrared data and the baseline infrared value, whether the trigger condition is satisfied, wherein the trigger condition includes whether the captured infrared data exceeds the baseline infrared value and whether a variance in the captured infrared data over a configurable time period is below a variance threshold; 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: A method of auxiliary data capture control includes: storing, at a data capture device, (i) detection criteria corresponding to events having respective event identifiers; and (ii) a registration indicator associated with at least one of the event identifiers; controlling a primary data capture sensor to obtain primary captured data; in response to detecting, based on the primary captured data, that the detection criteria are satisfied for a detected one of the event identifiers, determining whether the registration indicator is associated with the detected event identifier; and when the registration indicator is associated with the detected event identifier, 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 decoding, during a timeout period at one or more processors of the symbology scanner, a first indicia in a first image captured during the timeout period to determine a first indicia payload; conveying, during the timeout period at the one or more processors, the first indicia payload to a point-of-sale (POS) system for affecting a transaction; detecting, during the timeout period at the one or more processors, a second indicia in the first image or in a subsequent image captured during the timeout period; and in response to determining that the second indicia is the same as the first indicia and is decodable, determining a potential scan avoidance attempt and generating a scan avoidance alarm signal.
