A reader device is configured to wirelessly read medical information from a medical identification device and location information from a location identification device when the devices are within a range of the at least one reader device. A tracking device receives an indication that first medical information and first location information was read at a first location when a first medical identification device associated with the first medical object and a first location identification device associated with the first location was read at the first location by at least one reader device, and a last-known location of the first medical object associated with the medical identification device is generated based on the first location information read at the first location. In response to receiving a tracking request for a delivery status of a first medical object, the last-known location is provided display responsive to the tracking request.

Examples provide for a mobile computing device to include a camera, a processor and a memory resource to store a printing control application. In examples, the processor can execute the printing device control application to control the camera to capture a series of images of a region surrounding the mobile computing device using a plurality of image setting. Additionally, the processor can process individual images of the series of images using a corresponding image setting of the plurality of image settings and detect, by processing the individual images, a graphical encoding element in at least a first image of the series of images, using the corresponding image setting of the at least first image. Upon the processor detecting the graphical encoding element, the processor can perform operations to implement an encoding recognition state to interpret an encoding of the detected graphical encoding element.

The disclosed embodiments are generally directed to improving feature detection of rapidly acquired images using camera-enabled mobile devices involving a 2-D decal code, such as a QR code, for improving the reading accuracy of a rapid diagnostic antigen or antibody or enzymatic colorimetric directed test, such as for COVID-19 diagnosis. One primary issue with evaluating a Covid-19 rapid test is detecting and quantifying positive test lines from sampled test strips based on digital images of the test strip. Aspects of the present invention contemplate masking a QR code to improve the sample image resolution and contrast. Other aspects of the present invention contemplate methods and techniques to evaluate a test line on the sample image by enhancing an intensity curve along the test line and control line containing area by way of calculating the instantaneous change in pixel intensity and evaluating the position and intensity of those signals.

A bioptic scanner optical arrangement with a single sensor split four ways is disclosed herein. An example bioptic scanner optical arrangement includes a housing, an imaging assembly having a primary FOV, a decode module, a generally horizontal window supported by the housing, a generally upright window supported by the housing, and a mirror arrangement positioned within the interior region. The mirror arrangement is configured to divide the primary FOV into a plurality of subfields, to redirect at least two of the plurality of subfields through the generally horizontal window, and to redirect at least another two of the plurality of subfields through the generally upright window. The bioptic barcode reader has no other imaging assembly communicatively coupled to the decode module and used to process images for decoding indicia.

Systems and methods for point of sale age verification are disclosed. According to one disclosed embodiment, a system includes: a scanner configured to scan a passive data source on an identification card; and a processor coupled to the scanner, the processor configured to: receive a scanner signal from the scanner; verify an age of a user based on the scanner signal; and transmit verification information to a point of sale device, the point of sale device configured to authorize a sale of age-restricted material based on the verification information.

The present disclosure relates to a smart shopping cart, a server, a smart shopping system, and a method. The smart shopping cart includes a shopping cart body, an image capturing unit, and a display unit. The image capturing unit is configured to capture an image of a user face, such that the server identifies the image of the user face to obtain user identity information, query a user consumption history database based on the user identity information to obtain user consumption history data, generate user consumption interest data according to the user consumption history data, and generate product push information according to the user consumption interest data. The display unit is configured to receive and display the product push information.

A digital camera in a mobile device, such as in a smart phone, can be used for super-fast scanning of optical codes. The camera uses a wide-angle lens, high frames per second, very short exposure time, and/or a torch. For example, an ultra-wide angle camera can be used to provide a wide field of view and a large depth of field while decoding multiple optical codes.

There is provided a barcode detection device including an image sensor and a processor. The image sensor captures an image frame of a color barcode. The processor sequentially processes every row of the image frame to find at least one color segment in each row of the image frame, categorizes color segments of a same color in one cluster according to a position relationship and a color similarity of the color segments in the image frame, and recognize a color of the pixels in one cluster according to color parameters of pixels in said one cluster.

A method includes receiving, with an apheresis system, data associated with a donor; determining, based on the data associated with a donor, an identification of the donor; receiving, with the apheresis system, data associated with a blood component collection set; receiving, with the apheresis system, data associated with a plasma collection bottle; and performing, with the apheresis system, a plasma donation process based on the identification of the donor, the data associated with the blood component set, and the data associated with the plasma collection bottle. Receiving the data associated with the donor may include scanning, with a scanner, an image. The scanner is disposed on the apheresis system and the image may include one of a one-dimensional barcode or a two-dimensional barcode. The data associated with the donor may be displayed on a user device.
