Abstract: An exemplary system directs a camera included within a mobile device to capture a video feed, directs the mobile device to display the video feed within a display screen of the mobile device, and identifies a plurality of adjacent pixel blocks within the display screen that have signal characteristics that uniformly vary by more than a threshold amount over a predetermined time period. Based on the uniformly varying signal characteristics, the system determines that a pixel region constituted by the pixel blocks corresponds to a position of a display device within a field of view of the camera. The system identifies a media content instance being displayed by the display device, identifies augmented reality content associated with the media content instance, and directs the mobile device to display the augmented reality content within the pixel region of the display screen.

Abstract: An exemplary device renders, within a field of view of an immersive virtual reality world (“world”) presented on a display screen, content of the world based on a stream of a first content file comprising a first content sector of the world encoded in a high resolution and a second content sector encoded in a low resolution. The device detects user input to shift additional content included in the second content sector but not the first content sector into the field of view. In response, the device switches from receiving a stream of the first content file to receiving a stream of a second content file comprising the first content sector encoded in the low resolution and the second content sector encoded in the high resolution. The device then renders the additional content from the second content sector in the high resolution based on the second content file.

Abstract: An exemplary device renders, within a field of view of an immersive virtual reality world (“world”) presented on a display screen, content of the world based on a stream of a first content file comprising a first content sector of the world. The device predicts that a user will provide user input representative of a request to shift additional content included in a second content sector of the world but not the first content sector into the field of view. Based on the prediction, the device requests and begins receiving a stream of a second content file comprising the second content sector. The device then detects the predicted user input from the user and, in response, switches from rendering the content included in the first content sector based on the first content file to rendering the additional content included in the second content sector based on the second content file.

Abstract: A primary application and a secondary application installed on a mobile communication device are both configured to obtain input from a user of the device through an application session of the primary application. The primary application transmits a notification to cause the secondary application to begin execution in the background. The primary application further transmits a request for user interface (UI) information to the secondary application. Based on UI information received from the secondary application, the primary application generates a graphical user interface (GUI) including an interface for receiving user input relating to the secondary application. The generated GUI is displayed on the device in the application session of the primary application, and user input relating to the secondary application is received in the application session of the primary application. The primary application then transmits to the secondary application user input identified as relating to the secondary application.

Abstract: A mobile device executes an application installed on the mobile device to detect transmissions of broadcasted advertising packet data units (PDUs) via a short range wireless protocol. The mobile device receives a first broadcasted advertising PDU via the short range wireless protocol from a first Internet of Things (IoT) device, and the application determines a first geo-location associated with the first IoT device and generates a first timestamp based on receipt of the first broadcasted advertising PDU. The application at the mobile device forwards, via a wireless protocol that is different than the short range wireless protocol, the first broadcasted advertising PDU, the first geo-location, and the first timestamp to a remote data server.

Abstract: A mobile device pass through for signaling messages procedure allows smart devices to participate in and control multimedia communications by providing the ability to control multimedia communications to the smart device by the mobile device. A mobile device and a smart device establish a channel of communications between the mobile device and a web browser executing on the smart device, e.g. when both are connected to the same Wi-Fi access point. When the web browser accesses a web application that utilizes signaling messages to control multimedia content, the web browser will send signaling message requests to the mobile device. The mobile device, in turn, generates and forwards the signaling message. Media content is delivered directly to the smart device without passing through the mobile device or the established channel of communications.

Abstract: Systems and methods for application signing are disclosed. In some implementations, an application package identifier and a password may be received at an application signing server. Upon authenticating the application package identifier and the password, a fingerprint identifying the developer is received. Upon receipt of the fingerprint, the application signing server generates a secure key for the application based on the fingerprint, where the secure key is provided to the developer for inclusion within the application. Upon determining that the application package identifier and the secure key included in a request from an operating system of a mobile device matches an authorized application package identifier and an authorized secure key stored at the application signing server, the application signing server provides the requested list of the one or more APIs to the operating system to grant the application access to the APIs in the list.

Abstract: To reduce the contribution of data communications for background applications to network congestion, the examples implement techniques in which congestion detection leads a mobile device to impose restriction on data communications by any application running in the background. The mobile device may detect congestion and/or the need to restrict background data communications in response to a message or instruction received from a node of the network; or the mobile device may itself more directly detect congestion from monitoring and analysis of device/network interaction behavior and trends. Upon detecting congestion, the mobile device turns on a background data restriction. For example, with the restriction on, all applications only running in the background without direct user interaction are blocked from sending requests for data communication to/through the network. However, with the restriction active, the mobile device can still provide data communication in response to user interaction with the device.

Abstract: An application installed on a mobile device currently activated for service with a mobile wireless communication network captures information uniquely identifying a currently unsubscribed mobile device. The unique information may be captured from the currently unsubscribed mobile device via any of several short range transfer mechanisms. The application transfers the captured information and other information used to activate the currently unsubscribed mobile device to an activation service of the mobile wireless communication network, and the service activates the currently unsubscribed mobile device. In another example, a self-activation portal system determines an identifier of an owner of an account associated with an identifier provided by a user of a mobile device to be activated for use with a mobile wireless service. The system sends a message to the account owner offering options to accept or decline the activation request.
