Electromagnetic Interference in Implantable Pacemakers*

Pacing and Clinical Electrophysiology, 1978
The inhibited pacemaker (VVI or AAI) has become the most popular in recent years because of its ability to combine a physiological advantage with economical current consumption in cases with spontaneous activity. One of its disadvantages is its sensitivity to external electromagnetic interference. Though today's pacemakers possess, effective protection

Electromagnetic interference of CCTV

2015 International Conference on Information and Digital Technologies, 2015
All electronic and electrical devices generate interference signals that may effect on working other devices in the area. The paper describes a level of electromagnetic interference that IP cameras generate. The measurement must accomplish requirement according to the norm CSN EN 55022 ed.3.

Electromagnetic-Interference Control

IEEE Transactions on Electromagnetic Compatibility, 1980
The use of shield topology concepts to design interference control is described. Starting with the postulate that electromagnetic environments can he separated by closed shield surfaces, the proper design of essential compromises such as insulated power and signal conductors, and openings for access and ventilation are deduced. The role of grounding is

Electromagnetic Interference (EMI)

2002
Electric and magnetic signals originating outside of a defibrillator may affect its operation, a phenomenon known as electromagnetic interference (EMI). EMI usually refers to interference from environmental electromagnetic instrumentation and should be distinguished from other sources of electromagnetic noise causing ICD malfunction (Table 1).

Materials for Electromagnetic Interference Shielding

Journal of Materials Engineering and Performance, 2000
Materials for the electromagnetic interference (EMI) shielding of electronics and radiation sources are reviewed, with emphasis on composite materials and resilient EMI gasket materials, which shield mainly by reflection of the radiation at a high frequency.

Electromagnetic interference: A radiant future!

2015 IEEE 5th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2015
Although Electromagnetic Interference and Electromagnetic Compatibility are well established domains, the introduction of new technologies results in new challenges. Changes in both measurement techniques, and technological trends resulting in new types of interference are described.

Sources of Electromagnetic Interference

1987
Any device or apparatus that transmits, distributes, processes, or otherwise utilizes any form of electrical energy can be a source of EMI if any aspect of its operation generates conducted and/or radiated electromagnetic signals that can cause a degradation of performance of any other equipment or system that shares the same environment.

Intentional Electromagnetic Interference

2009
Intentional electromagnetic interference (IEMI) is an extension of the work by the well-known electromagnetic compatibility (EMC) and electromagnetic interference (EMI) communities. Additional threats have recently surfaced that suggest that various individuals and groups can build devices to intentionally cause electronic systems to fail.
