    Abstract: In accordance with one or more embodiments, a transmission device includes a receiver configured to receive an interfering signal via an antenna. A transmitter is configured to generate first electromagnetic signals conveying first data. A coupler is configured to generate first guided electromagnetic waves in response to combined electromagnetic signals, wherein the first guided electromagnetic waves propagate, without requiring an electrical return path, along a surface of a transmission medium of a distributed antenna system. A cancellation circuit is configured to generate the combined electromagnetic signals, based on the interfering signal and the first electromagnetic signals, wherein the combined electromagnetic signals mitigate interference by the interfering signal with the first guided electromagnetic waves.

  • Patent number: 10311367
    Abstract: Recommendation systems are widely used in Internet applications. In current recommendation systems, users only play a passive role and have limited control over the recommendation generation process. As a result, there is often considerable mismatch between the recommendations made by these systems and the actual user interests, which are fine-grained and constantly evolving. With a user-powered distributed recommendation architecture, individual users can flexibly define fine-grained communities of interest in a declarative fashion and obtain recommendations accurately tailored to their interests by aggregating opinions of users in such communities. By combining a progressive sampling technique with data perturbation methods, the recommendation system is both scalable and privacy-preserving.

  • Patent number: 10313351
    Abstract: A method includes, after expiration of a first passcode, receiving, at an access point, a first access request from a first device. The first access request may be encrypted based on the first passcode. The method further includes determining whether an identifier of the first device is included in a device list associated with the first passcode. The device list includes identifiers of devices that accessed the access point using encryption based on the first passcode before the expiration of the first passcode. The method also includes, in response to a determination that the identifier of the first device is included in the device list generating, at the access point, data representing a second passcode by encrypting the second passcode using the first passcode. The method further includes sending the data representing the second passcode to the first device from the access point.

  • Patent number: 10311094
    Abstract: A method and system for description of synthetic audiovisual content makes it easier for humans, software components or devices to identify, manage, categorize, search, browse and retrieve such content. For instance, a user may wish to search for specific synthetic audiovisual objects in digital libraries, Internet web sites or broadcast media; such a search is enabled by the invention. Key characteristics of synthetic audiovisual content itself such as the underlying 2d or 3d models and parameters for animation of these models are used to describe it. To represent features of synthetic audiovisual content, depending on the description scheme to be used, a number of descriptors are selected and assigned values. The description scheme instantiated with descriptor values is used to generate the description, which is then stored for actual use during query/search.

  • Patent number: 10313036
    Abstract: A mobile device may be configured with multiple receivers (e.g., a cellular receiver, a broadcast receiver such as FM, AM, DTV, a satellite receiver, a NWR receiver, etc.). Upon receipt of an emergency alert message via at least one of the receivers, the mobile device, via an application installed on the mobile device, may extract the emergency alert message from a data channel of the broadcast. The mobile device, via the application, may process the extracted emergency alert message to determine if the emergency alert message is to be rendered via the device. And, if the emergency alert message is to be rendered, the mobile device, via the application, may format the extracted emergency alert message to conform to a standard format (e.g., Commercial Mobile Alert System, CMAS, format).

  • Patent number: 10312965
    Abstract: Disclosed is a method and apparatus for reducing outbound interference in a broadband powerline communication system. Data is modulated on first and second carrier frequencies and is transmitted via respective first and second lines of the powerline system. A characteristic of at least one of the carrier signals (e.g., phase or amplitude) is adjusted in order to improve the electrical balance of the lines of the transmission system. This improvement in electrical balance reduces the radiated interference of the powerline system. Also disclosed is the use of a line balancing element on or more lines of the powerline system for altering the characteristics of at least one of the power lines in order to compensate for a known imbalance of the transmission system.
