  • Publication number: 20120289621
    Abstract: The invention relates to a method for functionalising a thermoset, crosslinked isocyanate-based polymeric solid material which is made of isocyanate and isocyanate reactive components, at least one of which comprises an anchor component which has at least one anchor group. The anchor groups on the solid material are formed by terminal alkene and/or alkyne groups. To functionalise this polymeric solid material it is brought in contact with a solution which contains at least one functional component. This functional component comprises at least one thiol group and is allowed to bind covalently to the polymeric solid material by a free-radical addition reaction between the thiol groups on the functional component and the terminal alkene and/or alkyne anchor groups on the undissolved solid material. An effective functionalisation of the polymeric material can thus be achieved notwithstanding the heterogeneous reaction conditions.

  • Patent number: 8266553
    Abstract: An integrated circuit device layout and a method for detecting mask data handling errors are disclosed in which integrated circuit device layout includes a device region in which operable circuitry is disposed. Integrated circuit device layout also includes a verification region in which verification elements are disposed. The verification elements include cells that are duplicates of at least some of the different types of cells in device region and can include structures that are duplicates of at least some of the types of structures in the device region. The patterns in verification region are used in the final verification process to identify mask data handling errors in a mask job deck. Because the patterns in verification region are easy to locate and identify, the time required to perform the final verification process is reduced and the chance of error in the final verification process is reduced.

  • Patent number: 8155739
    Abstract: Therapy optimization includes tracking electrode motion using an electroanatomic mapping system and generating, based on tracked electrode motion, one or more mechanical dyssynchrony metrics to thereby guide a clinician in therapy optimization (e.g., via optimal electrode sites, optimal therapy parameters, etc.). Such a method may include a vector analysis of electrode motion with respect to factors such as times in cardiac cycle, phases of a cardiac cycle, and therapy conditions, e.g., pacing sites, pacing parameters and pacing or no pacing. Differences in position-with-respect-to-time data for electrodes may also be used to provide measurements of mechanical dyssynchrony.

  • Patent number: 8063654
    Abstract: An integrated circuit device includes a stacked die and a base die having probe pads that directly couple to test logic of the base die to implement a scan chain for testing of the integrated circuit device. The base die further includes contacts disposed on a back side of the base die and through-die vias coupled to the contacts and coupled to programmable logic of the base die. The base die also includes a first probe pad configured to couple test input, a second probe pad configured to couple test output, and a third probe pad configured to couple control signals. Test logic of the base die is configured to couple to additional test logic of the stacked die to implement the scan chain. The probe pads are coupled directly to the test logic such that configuration of the programmable logic is not required to implement the scan chain.

  • Patent number: 7969706
    Abstract: A lightning-protected conductive composite fuel tank includes a conductive material arrayed on an outer surface to at least partially cover a fastener centerline. Through holes extend along the fastener centerline through the conductive material and the underlying fuel tank shell. These through holes are countersunk into the fuel tank shell to a depth such that a fastener in a through hole will avoid electrical continuity or communication with the conductive material on the fuel tank outer surface. The gap in the countersunk through holes, between the fastener heads and the coextensive outer surface of the fuel tank, is filled with a dielectric or nonconductive material.
