Systems and methods for automatically locating web-based social network members

Deciding whether to contact a particular friend, classmate, or coworker often hinges on where the person is located and what that person is doing. Such a decision typically has to be made in a limited amount of time with a limited amount of information. Further, when a person arrives at a particular location, such as a park or shopping mall, they often want to know if someone else they know is also at the same location. There is thus a need for systems and methods for automatically locating web-based social network members. The present invention relates generally to web-based social networks, and more particularly to systems and methods for automatically locating web-based social network members, is the subject of a patent recently obtained by Facebook.

Text-based communication control for personal communication device

This patent, assigned to Apple, relates to text-based communication devices. The proliferation of computers and compact portable devices has led to vast amounts of text-based communication. One problem with text-based communications is that there is no way to monitor and control text communications to make them user appropriate. For example, users such as children may send or receive messages (intentionally or not) with parentally objectionable language.

Method of Production of Graphene

The present invention relates to a method of production of graphene, notably employing a stage of annealing under irradiation.Graphene is a two-dimensional crystal in the form of a sheet of carbon, in which the atoms are positioned following a regular order of hexagonal structure, the thickness of this sheet corresponding to that of a carbon atom, thus corresponding to a thickness of less than a nanometre.
