Mobile wireless terminals, such as vehicles in traffic, can determine the relative positions of other vehicles with improved precision by arranging to acquire GNSS (global navigational satellite system) signals simultaneously, and then analyzing the various data sets differentially. Simultaneous acquisition can cancel many important errors such as motional errors of the vehicles, atmospheric distortions, and satellite timebase errors. Differential analysis to determine the relative positions of vehicles (as opposed to their overall geographical coordinates) can reduce errors related to satellite ephemeris and velocity, as well as roundoff errors. Localization with a precision of less than 1 meter can greatly improve collision avoidance while discriminating near-miss scenarios from imminent collisions, according to some embodiments. Messaging examples, in 5G and 6G, to manage the simultaneous acquisition and differential analysis, are provided in examples. Many other aspects are disclosed.

Systems, methods, apparatuses, and computer program products for using a web browser extension or plug-in component to receive scanned barcode data. One method may include validating, by a computing device, machine-readable data, generating, by a computing device, at least one event based upon the validated machine-readable data, and publishing, by the computing device, the at least one event according to a rendering component.

A method and computer platform configured to engage a web browser running on a mobile device and displaying an ecommerce website, instruct the web browser to activate a camera module of the mobile device to capture an image using a camera of the mobile device, and update the ecommerce website that is displayed on the web browser to include product information associated with the image.

An automated system/method for identifying and enabling viewer selection/purchase of products or services associated with digital content presented on a display device. Products within the digital content are identified and existing product placement data is ascertained. For products that do not include such data, other methodologies, with the assistance of third-party servers, are employed to assess identity and purchase availability. Viewer input designate products to assess or products can be automatically assessed. Viewers initiate purchase of identified products via the display device or other electronic devices controlled by viewers, such as via viewers' smart phones. Various processes for identifying products include use of AI processing, access to data on third-party servers, crowd sourcing and other methodologies. Various techniques for selecting products for purchases are employed including employing 3D codes (e.g., QR codes) alongside presented products to enable other portable electronic devices to facilitate purchase. Other features are described.

A first computing device of a multi-part code system includes one or more optical scanners and a network application associated with a network computing device of the multi-part code system. The network application is operable to obtain a second portion of a code associated with a second computing device. The network computing device generated the code for an interaction between the first and second computing device. The network application is further operable to display the second portion of the code on a display area of an interactive display, receive a first portion of the code, and instruct a user to drag the first portion of the code to the display area to align with the second portion of the code. When the first and second portions of the code are aligned, the network application produces the code and sends a finalized interaction notification to the network computing device.

A method for authenticating an online transaction or a log-in process is provided. The method comprises: receiving image data of a visual graphical barcode from a user device, and the visual graphical barcode is configured to be displayed on an unauthenticated device for conducting the online transaction; analyzing the image data to obtain a transaction validation identifier (ID); comparing the transaction validation ID to a pre-stored validation ID; comparing a first set of collection data from the user device to a second set of collection data that is pre-stored; and determining whether to approve or reject the online transaction based on (1) a match between the transaction validation ID and the pre-stored validation ID, and (2) a match between the first set of collection data and the second set of collection data that is pre-stored.

Systems and methods configured to determine a machine-readable optical code based on screen-captured video are disclosed. Exemplary implementations may: monitor, in an ongoing manner, a directory to determine whether a screen-captured image is added; effectuate, responsive to the determination that the screen-captured image is included in the directory, an image decoding machine configured to parse and decode images and/or the video frames for information embedded into the images and/or the video frames to: parse the screen-captured image for a machine-readable optical code; extract embedded information from the machine-readable optical code; and decode the embedded information for metadata; and effectuate, via the user interface, presentation of information derived from the metadata.

Embodiments position a barcode reader, or other optical detector, to scan upright barcodes when the user hand is in the neutral position. To do this, embodiments rest the body of the ring scanner device on top of the index finger, with the palm facing inward toward the users body. Embodiments have integrated interactivity, including a touchscreen display and separate buttons that can be used to operate the optical detector and input data into an integrated computing device. The integrated computing device can run software applications on board the ring scanner device. Finally, the integrated computing device can be remotely managed.

The present disclosure provides a display device, a display apparatus, and a method for manufacturing a display device. The display device comprises a mainboard, a display panel disposed on the mainboard, and a fingerprint recognition sensor. The fingerprint recognition sensor is disposed on the mainboard, and the fingerprint recognition sensor is located between the mainboard and the display panel. A groove is formed on a surface of the display panel facing the mainboard, and an orthographic projection of the groove on the mainboard corresponds to a position of the fingerprint recognition sensor. The groove is configured to form an air gap between the fingerprint recognition sensor and the display panel.
