  • Patent number: 8902734
    Abstract: A system and method for providing communication connection resilience between a mobile subscriber device and a network, such as the Internet. In one aspect, the invention provides improved communication connection resilience by using multiple nodes in multiple chassis to create redundant communication routes and to provide redundancy for control data relating to a mobile subscriber device. In one embodiment, a first node resides in a first chassis and a second node resides in a second chassis, and when an active communication link between the mobile subscriber device and the network via the first node becomes disrupted, the active communication link is rerouted such that data is communicated between the mobile subscriber device and the network via both of the first and second nodes.

  • Patent number: 8885562
    Abstract: A method, in a first network element of an inter-chassis redundancy (ICR) system, of cooperating with a second network element of the ICR system to provide ICR. The network elements are coupled by a synchronization channel. IP addresses are announced with a favorable traffic direction attribute. It is determined that the second network element either has announced the IP addresses with an unfavorable traffic direction attribute less favorable than the favorable direction attribute, or has not announced the IP addresses. Sessions that are connected through the IP addresses are handled. Session state synchronization messages that include session state for the handled sessions are transmitted over the synchronization channel to the second network element. It is determined, after an occurrence of a failure event that inhibits the first element from handling the sessions, that the IP addresses have been announced by the second network element with a favorable traffic direction attribute.

    Abstract: The present invention discloses an interventional medical device and methods of making the same. At least one coating layer is disposed on the outer surface of the interventional medical device and the material of the outmost layer of the coating layer is a sulfonate group-containing polymer. In the present invention, the material of the outmost layer of the interventional medical device is a sulfonate group-containing polymer. The polymer is endowed with a same surface property as that of heparin in addition to appropriate hydrophilicity due to the presence of the sulfonate group. After the interventional medical device is implanted into the human body, a hydrophilic surface is formed on the outer surface of the interventional medical device which is also negatively charged in the body fluid. Therefore, cells can easily adhere and grow on the outer surface thereof as a result of the enhanced cell compatibility.

  • Publication number: 20120273781
    Abstract: A method and device are provided for the RF characterization of nanostructures and high impedance devices. A two-terminal electronic nanostructure device is fabricated by dividing a length of a nanostructure into a plurality of shorter, identical nanostructures using a plurality of finger electrodes electrically connected in parallel. The nanostructure may include a single walled carbon nanotube subdivided into shorter identical copies of a metallic nanotube segment by situating multiple finger electrodes along the length of the single walled carbon nanotube. Each of the subdivided shorter nanotube segments are connected in parallel. This arrangement allows for close impedance matching to radio frequency (RF) systems, and serves as an important technique in understanding and characterizing metallic (and even semiconducting) nanotubes at RF and microwave frequencies.
