Abstract: A vent grid has parallel first electrically-conductive members and parallel second electrically-conductive members intersecting with the first electrically-conductive members. The intersection between the first and second electrically-conductive members is forced to have a larger cross-sectional area. The characteristic impedance thus increases. The electric current flowing through the first and second electrically-conductive members turns over at the boundary between the intersection and the first and second electrically-conductive members. The flow of the electric current is in this manner interrupted. Accordingly, the vent grid fails to induce electromagnetic wave. Moreover, the electrically-conductive piece is merely located at a corner of the opening. Decrease in the percentage of the opening is thus suppressed to the utmost per a unit area. A sufficient airflow can be established through the vent grid. Decrease in the cooling efficiency and performance can be suppressed.

Abstract: A resilient, electrically conductive EMI gasket is disposed between two jaws. A cam-lever or other actuator is operably linked to the jaws. The cam-lever can be used to drive the jaws closer together, thereby squeezing the gasket and causing a portion of the gasket to protrude, preferably beyond an edge of at least one of the jaws.

The gap is closed against passage of EMI radiation without relying on device insertion force to cause the EMI gasket to adequately contact the mating surface. Alternatively, an inflatable resilient EMI gasket is in fluid communication with a pump, and an actuator is operably linked to the pump.
