  • Patent number: 11924896
    Abstract: Aspects of the subject disclosure may include, for example, a radio device that has first and second subscriber identity modules; radio resources; a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of establishing a first communications network connection associated with the first subscriber identity module; establishing a second communications network connection associated with the second subscriber identity module; determining a communications activity on the first communications network connection; pausing or suspending activities of the second communications network connection; and blocking use of the radio resources by the second communications network connection. Other embodiments are disclosed.

  • Publication number: 20220130154
    Abstract: A mesh of existing infrastructures is usable to identify user identities and communications devices with physical objects (e.g., transportation vehicles, apparel, etc.). A system can receive image data representative of images of physical objects captured (e.g., by a camera) at locations. The system can also receive signal data representative of signals from communications devices. Based on time data and location data associated with the image data and the signal data, the system can, after multiple iterations, determine whether one of the physical objects is correlated with one of the communications devices. In response to a correlation, the system can store in a record data (e.g., a container, database, etc.) data elements representative of the physical object and a second data element associated with the communications device.

  • Patent number: 10722421
    Abstract: Methods, systems, and products estimate distances to aid a visually impaired user of a mobile device. As the user carries the mobile device, a camera in the mobile device captures images of a walking cane. The images of the walking cane are analyzed to infer a distance between a tip of the walking cane and the mobile device. The distance may then be used by navigational tools to aid the visually impaired user.

  • Patent number: 9853960
    Abstract: Concepts and technologies are disclosed herein for a peer applications trust center. A trust client can execute on a client computer and a trust service can execute on a server computer to provide the peer applications trust center. The trust client or trust server can register applications. During registration, the trust server or the trust client can generate a public key or other identifier for identifying the registered application. If another application requests access to the registered application, the trust server or the trust client can determine if the request specifies a registered application by name. If the requestor is granted access to the application, the requestor can be issued a token. Tokens can be revoked, updated, replaced, or renewed for various purposes.

  • Patent number: 9515972
    Abstract: Messages directed to a mobile device are selectively routed to message servers based upon the capabilities of a network to which the mobile device is connected. According to an illustrative method disclosed herein, a network connectivity server receives a network identifier from the mobile device, the network connectivity server receives a request for routing instructions for the message, and the network connectivity server determines if the network identified by the network identifier is capable of delivering the message. The network connectivity server then instructs the message server to route the message according to a standard delivery method for a message type of the message or to a message conversion server computer based upon the determination. The message conversion server computer converts the message into a new message type that the network is capable of delivering to the mobile device.
