    摘要: An apparatus has a permittivity attenuation layer interposed between a substrate and a first conductive trace, wherein the permittivity attenuation layer comprises a resin matrix containing functionalized carbon nanomaterial, such as functionalized single-wall carbon nanotubes (f-SWNTs). In some embodiments, a design structure for designing, manufacturing, or testing the apparatus is tangibly embodied in a machine readable medium. In some embodiments, the apparatus comprises an enhanced laminate core for use in a printed wiring board (PWB) that contains a differential pair having an inner-leg conductive trace and an outer-leg conductive trace. A permittivity attenuation layer is interposed between the inner-leg conductive trace and a laminate core, wherein the loading level of f-SWNTs in the permittivity attenuation layer is selected to attenuate the permittivity of the inner-leg conductive trace to match the permittivity of the outer-leg conductive trace.

    摘要: An apparatus suitable for EMC shielding applications comprises a first component comprising an electrically conductive first surface, and a gasket member comprising an electrically conductive exterior surface. The exterior surface is configured to couple with an electrically conductive second surface of a second component. The apparatus further comprises an adhesive layer disposed between the first component and the gasket member. The adhesive layer comprises an arrangement of conductive fibers, the conductive fibers extending along respective long axes between the first surface and the exterior surface.

    摘要: A method for managing data communication traffic in a network routing device includes monitoring a bandwidth utilization of the network routing device and determining whether the bandwidth utilization exceeds a threshold. The method may additionally include receiving a first signal, the first signal having a first bandwidth, the first signal further having stream of packets. A second signal may be generated based on determining that the bandwidth utilization exceeds the threshold. The second signal may include the stream of packets. The second signal may additionally have a second bandwidth, where the second bandwidth is larger than the first bandwidth. The method may be continued by routing the second signal along a loopback path external to the network routing device. The method may then include extracting, based on determining that the bandwidth utilization is at or below the threshold, the stream of packets from the second signal for processing.

    摘要: A system and method for controlling an EMC protection apparatus in a removable component. The removable component is inserted into an end product. As a result of the insertion power is applied to the EMC protection apparatus. A determination is made as to whether a power good signal is detected within the removable component. In response to a power good signal, an EMC protection device is rotated from a retracted state to an engaged state such that the EMC protection device is placed over an enclosure opening in the removable component forming an EMC seal. Full functionality of the removable component can be delayed until such time as the rotation is completed.
