A system and method for mitigating EMI in an electronic device rely on a set of foam dummy plugs specially configured for insertion into socket connectors according to connector type. The foam plugs have no electrical terminals or wiring, but are made from a foam composite material that attenuates electromagnetic radiation by absorption. The foam composite material includes a foam matrix and electrically conductive particles impregnated within the foam matrix. A handle may be unitarily formed with the foam plug. The handle may include a stamped through-hole, forming a ring, to facilitate insertion and removal of the dummy plugs by hand.

The average EMR emissions of an electronic device may be reduced by implementing an electrically-active modulated termination. For example, the impedance may be continuously varied at one or more termination locations between two metal substructures to cause a like variation in the amplitude of each component of the EMR. According to one approach, cyclically varying the electrical impedance with a period of less than the time interval over which the EMR is measured will result in a reduction in the average measured EMR.

An isolated signal probe comprises an input module, an output module, and a fiber optic line connecting the input module to the output module. The input module includes external positive and negative terminals, an input translation circuit electrically connected to the external positive and negative terminals, a first power supply for driving the input translation circuit, and an electrical-to-optical converter that receives a first signal from the input translation circuit. The output module includes an optical-to-electrical converter, an output translation circuit for receiving a second signal from the optical-to-electrical converter; a second power source for driving the output translation circuit, and an output connector electrically connected to the output translation circuit. The fiber optic line connects the electrical-to-optical converter to the optical-to-electrical converter.

A method of mitigating EMI in an electronic device includes selecting a subset of surface-mount socket connectors on an electronic device to be connected with corresponding working plug connectors and connecting the working plug connectors with the selected subset of socket connectors by inserting the working plug connectors into the selected subset of socket connectors. The method further includes positioning a dummy plug in each of the unselected surface-mount socket connectors, the dummy plug comprising a flexible foam material configured to attenuate electromagnetic radiation by absorption and having a dummy plug profile generally matched to a socket profile of the corresponding socket connector.

Systems and methods for preventing leakage of electromagnetic waves from electronic devices, or for preventing unwanted RF fields from entering an electronic device. According to an aspect, a system includes a body and a cover positioned to define an enclosed interior space for placement of an electronic device. The system also includes a gasket attached to or integrated one of the body and cover to seal the interior space from outside the electronic device enclosure. Further, the system includes an electromagnetic wave absorptive material attached to a portion of the gasket for absorbing electromagnetic waves generated within or outside of the electronic device enclosure.

Detecting electrostatic discharge (“ESD”) events in a computer system, includes: determining, from an ESD detector installed in the computer system, that an ESD event has occurred; identifying a component of the computer system within a predefined proximity to the ESD detector as possibly affected by the ESD event; and notifying a user of the computer system of the component possibly affected by the ESD event.
