In the vertical configuration, the first window is in a generally upright orientation.

The present invention provides a product label with a colorimetric sensor array and a code, and the system and the method of the present invention are mainly that the product label is attached to a fresh food, so that at least one sensing material of the colorimetric sensor array undergoes a chemical reaction with at least one metabolic molecule of the fresh food to change from an initial color to an indicating color. The present invention, by obtaining an image comprising an appearance, the code and the indicating color of the fresh food through an image acquisition device, also provides an instant information associated with the fresh food by a processing device according to a comparison result of the image and a database.

A barcode reader having calibration of scanner image brightness with multiple FOVs from a single sensor is disclosed herein. An example barcode reader includes an imaging system having a first and second FOV. A first illumination system is configured to illuminate the first FOV. The first illumination system has a first tolerance range and a first characteristic. A second illumination system is configured to illuminate the second FOV. The second illumination system has a second tolerance range and a second characteristic. The first characteristic is established to achieve a minimum desired brightness at a beginning portion of the first tolerance range and a maximum desired brightness at an end portion of the first tolerance range. The second characteristic is established to achieve a minimum desired brightness at a beginning portion of the second tolerance range and a maximum desired brightness at an end portion of the second tolerance range.

A self-service checkout apparatus includes dispensers each configured to dispense an article, first sensors each configured to detect a presence of the article in the corresponding dispenser, first indicators each configured to indicate that the presence of the article in the corresponding dispenser, a second sensor configured to detect whether a user is present, and a processor configured to, when one or more articles are detected by the first sensors and the user is detected by the second sensor, perform first notification using the respective one or more of the first indicators, and when one or more articles are detected by the first sensors and the user is not detected by the second sensor, perform second notification according to a priority order predetermined for each article, using at least one of a second indicator of the self-service checkout apparatus and a third indicator of another apparatus.

A barcode scanning device for determining an object orientation of an object includes: a barcode reader; a decoding processor interconnected with the barcode reader, the decoding processor configured to: control the barcode reader to read the barcode and generate barcode data representing the barcode; and an orientation processor interconnected with the decoding processor, the orientation processor configured to: receive the barcode data and determine a barcode orientation based on the barcode data; determine the object orientation based on the barcode orientation; and output an indication of the object orientation.

A method of optically scanning indicia on an object includes providing a coherent light source for illuminating the object with coherent light. The object is marked with indicia including a first feature and a second feature, with the first feature including reflection of coherent light and said second feature including emittance of non-coherent light when illuminated. An imaging device is capable of distinguishing coherent light from non-coherent light. The indicia are illuminated with coherent light generated by the coherent light source causing the indicia to reflect coherent light and emit non-coherent light. The coherent light is distinguished from the non-coherent light emitted from the indicia by a controller for identifying a pattern of one of said first feature and said second feature.

A detection device, which includes a scanning module, a detection module operated at a distance from the scanning module, and an evaluation unit. The scanning module includes a laser light source for generating a laser beam, a deflection unit to deflect the beam, and a control unit for controlling the laser light source and the deflection unit, so that the beam is moved in a scanning pattern. The detection module includes a light detector, with which the light of the beam reflected on an object in the beam path is detected and converted into a received signal. The first laser light source is controlled so that the beam is modulated as a function of its deflection and in this way is provided with synchronization marks. The evaluation unit identifies these synchronization marks in the received signal and synchronizes the received signal with the deflection of the beam based on them.

Disclosed are barcode scanners and methods for scanning a barcode. The barcode scanners and methods for scanning a barcode may include receiving a raw image from a scanner. Channel information may be extracted from each pixel of the raw image. A composite image may be created using the channel information from each pixel of the raw image. Finally, product information may be extracted from the composite image.

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.
