20110305146 | Carrier Signals For Synchronization - Disclosed herein are methods and systems that may help a WiMAX base station function without a GPS signal by providing a high-stability reference signal via a subcarrier of a broadcast signal, such as an FM radio signal. An exemplary broadcast station may therefore be configured to phase-lock a subcarrier signal to a GPS signal, and include this subcarrier in its broadcast signal, thereby providing the subcarrier signal for use by a base station as a high-stability reference signal for local-oscillator stabilization at the base station. The broadcast station may further modulate a timing signal onto the subcarrier signal. An exemplary base station may therefore receive the broadcast signal, decode the broadcast signal to acquire the subcarrier signal, and use the subcarrier signal to stabilize its local oscillator, rather than using a GPS signal. The base station may further demodulate the subcarrier to acquire the timing signal, which the base station may use for frame-start synchronization, instead of a GPS signal. | 12-15-2011 |

20150055636 | Alternatives To Satellite Signals For Synchronization In Macro Network - Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality. | 02-26-2015 |

20120124146 | Messaging System with Multiple Messaging Channels - A messaging system facilitates communication between users through various messaging channels. The messaging system supports multiple communication channels and includes a messaging module that automatically selects one or more of the messaging channels for delivering a message to a recipient of the message using, for example, a set of policy rules or a trained model. The messaging module may also provide, in a user interface for sending and receiving messages, a visual indication of the selected messaging channel to the sender of the message to provide the user with transparency about how the message will be delivered. Additionally, the message may be delivered via multiple messaging channels, where the messaging module may rescind messages from some of the messaging channels upon receiving a reply from the recipient of the message or other confirmation that the recipient has seen the message via one of the communication channels. | 05-17-2012 |

20130191466 | Claiming Conversations Between Users and Non-Users of a Social Networking System - Users of a social networking system initiate conversations between other users and additional users who may not be registered to use the social networking system. Each additional user is identified by an item of contact information, and conversation messages are sent to an additional user using the contact information. The conversations are associated with the item of contact information and saved in the social networking system. A user of the social networking system may subsequently claim the item of contact information. The claiming user is given access to the associated conversations if the social networking system can verify that the item of contact information belongs to the claiming user. | 07-25-2013 |
20140089418 | STRUCTURING NOTIFICATIONS OF EVENTS TO USERS IN A SOCIAL NETWORKING SYSTEM - A social networking system identifies an event based on a thread including messages from users of the social networking system and communicates invitations to the event to one or more invited users. The social networking system receives a response to an invitation from a responding user and identifies a group of users invited to the event that have not responded to the invitation. From the users invited to the event that have not responded to the invitation, a subset of users having a threshold affinity to the responding user are selected. The social networking system notifies the subset of users of the responding user's response to the invitation and may also provide the subset of users with a suggestion for attending the event. | 03-27-2014 |
