    摘要: A computer system including a number of option bays that accommodate optional peripheral equipment, such as CD-ROM drives, DVD drives, magnetic tape backup systems and Zip drives. An unpopulated bay is segmented into compartments by a divider that extends through substantially the entire depth of the bay so that each of the compartments operates as a waveguide beyond frequency cutoff (WBFC). The resulting compartments are characterized by cross-sectional dimensions that are less than the cross-sectional dimensions of the bay, so that the compartmentalization effects substantially enhanced attenuation of electromagnetic signals having a frequency at the highest expected operating frequency of the computer system.

    摘要: An EMI gasket (20) includes a plurality of serrations (34) along at least one edge (35, 36). The serrations (34) are arranged side-by-side so that each may be articulated individually. That is, one of the serrations (34) may be displaced significantly out of the plane of the gasket without affecting adjacent serrations. Thus, when the edge of the gasket (20) is compressed between two surfaces which include a discontinuity (40) such as a step or protuberance between them, the serration in contact with the discontinuity is displaced out of the plane of the gasket without displacing adjacent portions of the gasket. Allowing a portion of an EMI gasket (20) to be displaced out of the plane of the gasket without affecting adjacent portions of the gasket substantially reduces or eliminates gaps which occur due to the failure of the gasket to precisely follow the contour of a component.

    摘要: An electrostatic discharge testing system includes a measurement chamber to hold a discharge electrode and a target electrode in separation from each other, a first conductive path to supply an ESD pulse to the discharge electrode, and a second conductive path to receive a discharge pulse from the target electrode. A transmission line, field-coupled to the second conductive path, generates a measurement signal in response to the discharge pulse.
