A first layer is formed on the first electromagnetic insulating layer, the first layer having a plurality of first conductive rings composed of first conductive material, each first conductive ring being separated by first insulating material. A second electromagnetic insulating layer is formed on the first layer. A second layer is, formed on the second electromagnetic insulating layer, the second layer having a plurality of second conductive rings composed of second conductive material, each second conductive ring being separated by second insulating material. A third electromagnetic insulating layer is formed on the second layer. The second conductive rings of second conductive material are positioned such that a second conductive ring overlaps a portion of a first conductive ring and overlaps a portion of a second conductive ring, the second conductive ring being adjacent to the first conductive ring. The second electromagnetically insulating layer is composed of a self-healing dielectric material.

摘要： A segmentation and re-assembly (SAR) decode engine receives protocol data units of data from a communication channel between two computers, sequences the protocol data units, and re-assembles the data in the protocol data units into the messages exchanged by the computers. The SAR decode engine is responsible for unpacking the payloads from the protocol data units as instructed by a protocol interpreter associated with the protocol data unit, and for creating and maintaining a flow object database containing flow objects representing the data flows at each protocol layer. The SAR decode engine creates a protocol flow object for each protocol layer and logically links the protocol flow object to circuit flow objects that define two one-way circuits within the channel. The circuit flow objects linked to a protocol flow object are logical representations of the protocol data units for the next higher protocol layer. For protocols that fragment data, each circuit flow object is a vector list containing one or more vectors that define the length, starting location and position of the data fragments in the immediately lower layer circuit flow objects.

摘要： A medical device includes a pattern of electrically conductive material. The pattern of electrically conductive material has an anti-antenna geometrical shape such that the anti-antenna geometrical shape substantially prevents the medical device from creating an imaging artifact and/or substantially allows imaging of a volume within the medical device. The pattern may be formed by multiple “figure-8” shaped electrical conductors, multiple “figure-8” emulating electrical conductors, multiple sine-wave-like shaped electrical conductors, multiple zig-zag patterned electrical conductors, by multiple electrical conductors, each having sequential conductive loops, and/or a single conductor weaved into a loop mesh. The electrically conductive material may be titanium, tantalum, nitinol, stainless steel, and/or NbZr.
