  • Publication number: 20140282920
    Abstract: Dynamically selecting a DHCP server for a DHCP client terminal device, according to an example, includes: triggering, by a network device with a DHCP relay function, an authentication performed by an authentication server on a DHCP client terminal device user when receiving a DHCP packet for requesting a configuration parameter sent from a DHCP client terminal device; receiving, by the network device, an identity of a DHCP server designated by the authentication server for the DHCP client terminal device user when the DHCP client terminal device user passes the authentication, and establishing an entry for user information of the DHCP client terminal device user and the identity of the designated DHCP server; and matching, by the network device, the user information carried in a packet with established entries when receiving the packet subsequently sent from the DHCP client terminal device, and forwarding the packet using the identity of the DHCP server in the entry matching the user information.

  • Patent number: 8576785
    Abstract: A data communication method includes providing a sender node having a data packet of information. The data packet includes at least one first field and a second field. The second field has content that is dependent upon actual content of the at least one first field. The content of the second field of the data packet is transmitted from the sender node to a receiver node. The receiver node is used to predict the actual content of the first field of the data packet. The receiver node is used to calculate the content of the second field of the data packet based upon the predicted content of the first field. The predicted content of the first field is confirmed to be equivalent to the actual content of the first field. The confirming step includes comparing the calculated content of the second field to the transmitted content of the second field.

  • Publication number: 20110293522
    Abstract: Polymer surface modification method comprising the steps of first forming a surface of primary reactive end groups tethered to the polymer chain ends during fabrication of an article, and then modifying the reactive surface with bio-active molecules, hydrophilic and hydrophobic monomers, oligomers, or polymers to attain specific surface properties. Alternatively, a multifunctional coupling agent can be used to couple the primary reactive group to a second reactive group capable of reacting with a functional group associated with bio-active molecules, hydrophilic and hydrophobic monomers, oligomers, and polymers to attain specific surface properties. The invention involves bringing reactive endgroups to the surface with surface active spacer attached to the polymer chain end. The surface active spacer allows the migration and enrichment of reactive end groups to the surface during fabrication.

  • Publication number: 20110257027
    Abstract: Polypeptide substrates based on modifications or fragments of the various APP isoforms, assay methods based on the use of these substrates, and screening methods directed toward identifying inhibitors of ?-secretase activity. The assay methods and the screening methods are adapted for use in high throughput multi-well plate assay apparatuses. In many embodiments the substrate polypeptides are labeled for ease of detection, and/or may bind specific ligands that themselves are labeled. Generally the labels promote high specificity as well as high sensitivity of detection. These features render the assay and screening methods that employ the labeled substrates especially suited for use in high throughput assay formats. This disclosure further identifies small polypeptides based on a subsequence motif of A? that are shown herein to be potent inhibitors of the activity of ?-secretase.

  • Publication number: 20110124772
    Abstract: Polymers with non-leaching antimicrobial activity and their use as surface coatings or bulk resins for medical devices. The antimicrobial polymers are prepared with antimicrobial moieties covalently bonded to a polymer chain end or to a polymer backbone at a side chain end. The antimicrobial moiety-containing endgroups include surface active (or surface assembling) moieties which promote enrichment of antimicrobial endgroups at the polymer surface and thus formation of an antimicrobially active surface. Polymers with built-in antimicrobial endgroups can be used as bulk resins, as antimicrobial additives, or as infection preventative coatings in the manufacture of medical devices (e.g., catheters, vascular access devices, peripheral lines, IV sites, drains, gastric feeding and tubes, and other implantable devices).

  • Patent number: 7884171
    Abstract: Polymers whose surfaces are modified by endgroups that include amphipathic surface-modifying moieties. An amphipathic endgroup of a polymer molecule is an endgroup that contains at least two moieties of significantly differing composition, such that the amphipathic endgroup spontaneously rearranges its positioning in a polymer body to position the moiety on the surface of the body, depending upon the composition of the medium with which the body is in contact, when that re-positioning causes a reduction in interfacial energy. An example of an amphipathic surface-modifying endgroup is one that has both a hydrophobic moiety and a hydrophilic moiety in a single endgroup. For instance, a hydrophilic poly(ethylene oxide) terminated with a hydrophilic hydroxyl group is not surface active in air when the surface-modifying endgroup is bonded to a more hydrophobic base polymer.
