    Abstract: Systems and methods for placement of an introducer needle into the subclavian vein. A needle for subclavian vein penetration includes a straight needle portion, a bent needle portion, and a hub. The bent portion allows for needle placement with minimized chance of complications. The needle and hub form a lumen through which a guide wire can be placed. The bent needle portion has an inner diameter substantially similar to the inner diameter of the straight needle portion to reduce resistance due to movement of the guide wire.

  • Patent number: 8533647
    Abstract: In order to realize some of the advantages described above, there is provided a computer-implemented method for verification of an intellectual property (IP) core in a system-on-chip (SoC). The method comprises generating a plurality of verification specific abstracted views of the IP core each of the plurality of verification specific abstracted views having a plurality of verification specific attributes at an input/output (I/O) interface of each of the abstracted view of the IP-core. A unified abstracted view of the IP-core is generated.
