  • Publication number: 20070154937
    Abstract: Compounds having two reactive functional groups are described that can be used as a tethering compound to immobilize an amine-containing material to a substrate. The first reactive functional group can be used to provide attachment to a surface of a substrate. The second reactive functional group is a N-sulfonyldicarboximide group that can be reacted with an amine-containing material, particularly a primary aliphatic amine, to form a connector group between the substrate and the amine-containing material. The invention also provides articles and methods for immobilizing amine-containing materials to a substrate.

  • Publication number: 20070110614
    Abstract: A device for detecting a compound in a sample includes a substrate and a self-assembled monolayer. The substrate includes a support with a metallized top surface, and the self-assembled monolayer includes an alkanethiol attached to the metallized top surface of the substrate and having a functional group that reversibly or irreversibly interacts with the compound. A liquid crystal is disposed on the self-assembled monolayer opposite the side of the self-assembled monolayer attached to the metallized top surface of the substrate. The liquid crystal includes a moiety that interacts with the functional group of the alkanethiol. When the compound is present in a sample that contacts the self-assembled monolayer, the orientation of the liquid crystal is altered.

  • Publication number: 20070041405
    Abstract: A discussion of improving integrated device deterministic response to test vectors. For example, limiting the transmission delay for an integrated device's response within known bounds by synchronizing an initialization training sequence to a reset deassertion. Specifically, the proposal facilitates response determinism from the DUT by synchronizing training sequences and subsequently synchronizing flit transmission to reset assertion as sampled by reference clock.

  • Publication number: 20060246260
    Abstract: A filter element in the form of a nonwoven self-supporting filtration web having rows of folded or corrugated spaced-apart pleats, the web containing continuous thermoplastic fibers a majority of which are aligned at 90°±20° with respect to the row direction. The filter element can be made by forming rows of pleats in such a nonwoven web and cutting the web to a desired size and shape. The filter elements can provide improved mechanical and filtration properties and can exhibit reduced susceptibility to pleat deformation and the loss of space between pleats.

  • Publication number: 20050259696
    Abstract: Embodiments of the invention provide an algorithm for dividing a link into one or more reduced-width links. For one embodiment of the invention, a multiplexing scheme is employed to effect a bit transmission order required by a particular cyclic redundancy check. The multiplexed output bits are then swizzled on-chip to reduce on-board routing congestion.

  • Publication number: 20050262284
    Abstract: A technique is described by which two link agents with ports coupled together using a point-to-point interconnect in a system exchange their link width support capabilities and negotiate a link width that is mutually agreeable. The interconnect between each pair of agents comprises a pair of uni-directional links having multiple electrical wires, or lanes, where one link is used by a first agent to transmit data to a second agent and another link is used by the second agent to transmit data to the first agent.
