Abstract: A method includes receiving location information from a mobile device, the location information indicating a location of a mobile device operating the mobile device in a global positioning navigation satellite system (GNSS)-location-denied environment. One or more communication parameters associated with communications between the mobile device and a network can be identified. The communication parameters can be associated with the location of the mobile device. The mobile device can provide the location information using a social networking site, for example, using a check-in feature or drop-down location menu.

Abstract: Systems and methods are provided for enabling social network navigation. The method at a client device comprises obtaining a node graph from a social networking service, the node graph comprising a plurality of nodes visualizing a social network, each node having an associated profile corresponding to a member in the social network; displaying the node graph; enabling navigation through the node graph to display portions of the node graph in corresponding views; updating the displayed node graph after receiving an update for at least one profile from the social networking service; and updating the displayed node graph after detecting a first interaction with at least one node in the node graph.

Abstract: Techniques for use in providing object indicators for video recording or playback are described. A mobile device includes a media recorder module and a sensor device. The media recorder module is used to record video data in a media file. The sensor device detects signals which indicate the presence of an object during a time period of the recording. The mobile device receives object data comprising an identification of the object, and stores the object data in association with timestamp data which corresponds to the time period during which the object is present during the recording.
