  • Method, apparatus, and system for establishing voice communication
    Patent number: 9332039
    Abstract: Methods, apparatus and systems for establishing voice communication are provided herein. An exemplary method can be implemented by an electronic device. A request initiated by a user can be received. The request can include one of a voice-communication request, a voice-communication-invitation request, a temporary-voice-communication request, a temporary-voice-communication-invitation request, an exclusive-voice-communication request, and an exclusive-voice-communication-invitation request. According to the request, a voice-room number can be obtained from a first server or a second server, without using third-party communication software. The method further includes starting a voice client and entering a voice room directly using the voice client, according to the voice-room number.

  • PROCESS FOR MODIFYING SUBSTRATES WITH GRAFTED POLYMERS
    Publication number: 20100256251
    Abstract: The present invention relates to a chemical process for modifying inorganic and organic substrates with thin polymer films that are grafted to a substrate. The preferred composition includes a dimethylamino terminated precursor that is deposited as a self-assembled monolayer onto a gold or silicon oxide, or other substrate. The polymerization is then initiated by irradiation with UV light in the presence of monomer and an optional photosensitizer.
