A firewall clustering system connects two or more firewalls between an internal network and an external network. The plurality of two or more firewalls are combined to supply high-availability and scaling of processing capacity. Firewalls maintain client-server state information. Flow controllers are connected to the firewalls and placed on both the internal “trusted” side and the external “untrusted” side of the firewalls. Flow controllers are placed on both sides of the firewalls to ensure that traffic for a given client-server session flows through the same firewall in both inbound and outbound directions. The firewalls perform filtering operations and/or network address translation (NAT) services. In both cases, the flow controllers supply high availability, scalability, and traffic distribution for the firewalls in the firewall cluster.

A distributed antenna system is provided for communicating with a plurality of base stations. The distributed antenna system includes a system controller and a master unit communicating with at least one of the plurality of base stations. A remote unit communicates over a high data rate media with the master unit and/or a downstream remote unit. Alternatively, the distributed antenna system includes a controller and a digital time/space crosspoint switch controlled by the controller. A digitizing transceiver is in communication with the digital time/space crosspoint switch. The crosspoint switch is configured to transmit and receive digital data through the digitizing transceiver.

Methods are provided for the synthesis and secretion of recombinant proteins preferably large mammalian proteins or hetero-multimeric proteins at high levels and for prolonged time in polyploid, preferably diploid yeast. These methods use various mating competent yeast, including Pichia. In a preferred embodiment, a first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.

A nano graphene-enhanced particulate for use as a lithium-ion battery anode active material, wherein the particulate is formed of a single sheet of graphene or a plurality of graphene sheets and a plurality of fine anode active material particles with a size smaller than 10 μm. The graphene sheets and the particles are mutually bonded or agglomerated into the particulate with at least a graphene sheet embracing the anode active material particles. The amount of graphene is at least 0.01% by weight and the amount of the anode active material is at least 0.1% by weight, all based on the total weight of the particulate. A lithium-ion battery having an anode containing these graphene-enhanced particulates exhibits a stable charge and discharge cycling response, a high specific capacity per unit mass, a high first-cycle efficiency, a high capacity per electrode volume, and a long cycle life.

A method for communication over a wireless local area network (WLAN) includes receiving uplink signals from a plurality of stations in the WLAN. Responsively to the uplink signals, a set of the stations is selected for inclusion in a spatial multiplexing group. Downlink signals are transmitted simultaneously to the stations in the set using spatial division multiplexing (SDM).

The present invention relates to novel electroactive energy storing polyacetylene-co-polysulfur (PAS) materials of general formula (C2Sx)n wherein x is greater than 1 to about 100, and n is equal to or greater than 2. This invention also relates to novel rechargeable electrochemical cells containing positive electrode materials comprised of said polyacetylene-co-polysulfur materials with improved storage capacity and cycle life at ambient and sub-ambient temperatures.

A method is described for preparing a niobium suboxide represented by the formula, NbO_x, in which 0.7<x<1.3. The method involves reacting NbO_y (in which y<1.8<2.1) with a stoichiometric amount of niobium metal, in the presence of hydrogen. The niobium suboxide produced by such method may be used to fabricate anodes for solid electrolyte capacitors.

A communication system (10) supports the provision of a plurality of dedicated communication resources (50–64), such as copper drops, RF links and optical fibers, to dedicated home-gateway devices (44–48) or distribution points (124). The communication resources (50–64) support broadband interconnection (104) between the dedicated home-gateway devices (44–48) or distribution points (124) and an access multiplexor (30) in a network (12). Each gateway device (44–48) or distribution point (124) generally includes a local RF transceiver (84) and associated control logic (80–82) that allows local communication (86) between gateway devices (44–48) and hence statistically multiplexed access (60–64, 89) to multiple communication resources, thereby providing increased bandwidth in uplink and/or downlink directions. With the control logic (80) operable to provide a routing and prioritisation/arbitration function, each gateway (44–48) is able to selectively engage use of supplemental, non-reserved communication resources usually associated with a dedicated ono-to-one connection between the access network (12) and at least one secondary gateway. Physical layer access to information routed via a secondary gateway within a virtual neighborhood network (90–92) comprising several gateways is restricted through an end-to-end encryption algorithm between an originating gateway and, at least, the access multilpexor (30).

A system and method capable of performing multiple types of non-invasive tomographic techniques. The system is capable, via electronic control, of detecting and imaging materials within a volume using electrical capacitance, displacement phase current, magnetic inductance, and magnetic pressure sensing. The system is also able to control the amplitude, phase, and frequency of individual electrode excitation to increase imaging resolution and phase detection. This allows many dimensions of non-invasive data to be captured without the need for multiple instruments or moving parts, at a high data capture rate.

A computer-implemented method for double auction trade-building by matching, based on feasibility and price/cost heuristics, a plurality of electronically posted bid with a plurality of electronically posted ask records. A one-pass sequential trade building method selects ask records one at a time and sequentially inserts, in one pass, as many of the bid records as possible while maintaining feasibility criteria. A two pass sequential trade building method inserts the bid records in two stages, the first terminating when the trade becomes feasible and the second when no further bids can be inserted.

A bioabsorbable interference screw having a tapered profile which extends along substantially the entire length of the screw. The tapered profile makes the screw easy to insert while providing superior fixation resulting from a progressively increasing diameter. Upon insertion, the screw engages cortical bone at the back end of the bone tunnel and fills all but 5-10 mm. of the tunnel, thereby providing increased fixation strength while also promoting fast healing. The screw includes a head provided with a specially designed drive socket with radially extending slots at its outer end for receiving corresponding protrusions on the shaft of screwdriver. The drive socket optimizes the torque capacity of the screw. To maintain wall thickness, the socket has a taper corresponding to the tapered outer profile of the screw. The taper of the socket also permits easy insertion of the tip and shaft of the driver into the screw.

A multi layered wound dressing for use on wounds producing high levels of exudate, the dressing comprising a transmission layer having a high MVTR; an absorbent core capable of absorbing and retaining exudates; and a wound contacting layer which transmits exudate to the absorbent core, the absorbent core and wound contacting layer limiting the lateral spread of exudate in the dressing to the region of the wound.
