    Abstract: An enhanced services display message protocol (ESDMP) facilitates display of messages in a compliant analog telephony device (ATD). An exemplary gateway device in a voice over packet (VOP) network can activate enhanced services in a compliant ATD using the ESDMP and includes a controller and first and second interfaces. One of the interfaces can transmit and receive communications over a VOP network. The other interface can transmit and receive voice band message data modulated according to a frequency shift keying (FSK) protocol. The ESDMP can be used to configure the gateway to activate features supported by the ATD, to update call state information and to display feature state information.

    Abstract: A fixed communication device includes a transceiver operable to transmit and receive communications to a gateway, and a processor cooperatively operable with the transceiver. The processor is configured to facilitate establishing a foreign exchange office (FXO) connection to the gateway over the transceiver; formatting a message in a multiple data message format (MDMF) message format; and transmitting the message from the transceiver to the gateway using frequency shift keying (FSK) modulation, after the FXO connection is established

    Abstract: The invention relates to a film comprising greater than 80 wt % single-wall carbon nanotubes wherein the tensile modulus is at least about 6 GPa at 0.2% strain and the conductivity of the film is at least about 70,000 S/m. The tensile modulus is typically about 8 GPa at 0.2% strain. The method for making the film comprises preparing a solution of single-wall carbon nanotubes in a superacid, such as oleum containing approximately 20 to 30% sulfur trioxide, under a dry, oxygen-free atmosphere. The solution is placed on a surface in a moisture-containing atmosphere, wherein the solution absorbs moisture and acid leaches out. The film is washed to further remove acid, dried, and, optionally, subjected to a heat treatment. Besides free-standing films, coatings of single-wall carbon nanotubes can be made on a variety of surfaces including polymers, glass, metals, and ceramics. The surfaces can be flat planes, fibers or contour shapes.

    Abstract: Providing interoperability on a voice communication network by detecting incompatible bit packing payload formats of ADPCM encoded voice data signals in an encoder/decoder. A mismatch of bit packing formats between little endian format and big endian format is determined through the use of a media gateway control protocol package called Real Time Protocol that allows a Call Agent to detect the presence of garbled audio and allows an intelligent gateway to detect the payload format being used by remote endpoints during call setup procedures and then switch the gateway's encoding for the payload to the payload format being used by the remote endpoint. The invention may be applied to an ITU G.726 encoder/decoder.

    Abstract: A conductive carbon nanotube film having high tensile strength and initial tensile modulus comprises primarily oxidized small-diameter carbon nanotubes wherein the diameter of the small-diameter carbon nanotubes are at most about 3 nm. A method for making the film comprises refluxing an aqueous mixture comprising carbon nanotubes and an oxidizing agent to form a refluxed nanotube dispersion; forming a carbon nanotube film from the refluxed carbon nanotube dispersion; optionally removing nitric acid or other oxidizing agent from the carbon nanotube film; drying the carbon nanotube film; and heat-treating the carbon nanotube film to form a heat-treated carbon nanotube film. The method can also comprise sonicating the nanotubes prior to or after refluxing. A heat-treated small-diameter carbon nanotube film can have a tensile strength of over 70 MPa and an initial tensile modulus of about 5 GPa.

    Abstract: The present invention relates to compositions comprising rigid-rod polymers and carbon nanotubes. The compositions comprise dispersed carbon nanotubes aligned with rigid-rod polymers. The alignment of the nanotubes and polymers can be liquid crystalline. The rigid-rod polymers of this invention include, but are not limited to, polymers and copolymers comprising benzobisazole, pyridobisimidazole and benzamidazobenzo-phenanthroline repeat units. Dispersion of carbon nanotubes is achieved by in-situ polymerization in the presence of the carbon nanotubes, which may be either single-wall or multi-wall or a combination of both. The polymer compositions comprising carbon nanotubes may be spun into fibers or formed into films. The strength of the resulting fibers of the present invention is significantly greater than that of fibers without carbon nanotubes.
