Electromagnetic Interference (EMI) Expert

Crosstalk: EMI and RFI

Electromagnetic interference (EMI) and RF Interference (RFI)—also known as crosstalk—are serious and increasing forms of environmental pollution. There are man made and natural sources of this interference. Regardless of the source, the effects can range from minor annoyances to potentially fatal accidents. EMI and RFI travel in invisible radio waves. They have the capacity to interrupt electrical and electronic equipment and communications systems.

These interruptions cause devices to malfunction, resulting in dangerous situations. Documented consequences of EMI & RFI crosstalk include:

Death of a heart patient when EMI disabled her heart monitor/defibrillator
Residential gas ovens turned on by cell phone emissions
Failure of a surgery patient’s anesthetic gas monitor
Powered wheelchairs and scooters spontaneously drive off curbs or piers
Apnea monitors malfunction and erroneously detect respiration

Even worse, crosstalk is often initially overlooked as a potential cause of accidents.

Wireless Expert

Wireless devices, networks, and signals are everywhere, impacting our daily lives. I lead investigations related to failures of these complex systems.

Telecommunications Expert

I help clients understand the technical issues surrounding complex telecom systems, including E911, 5G, LTE, Internet, GPS, RF, and radar systems.

An Overlooked Cause

EMI & RFI waves are ubiquitous. They can be caused by:

The sun
Lightning
Power lines
Automobiles
Consumer electronics
Motors
Switches
Heaters
Cell phone equipment
Microwave ovens
Electronic toys
Lighting systems
Radio transmitters

These interference waves are present at some level all the time. They can be dangerous when they interact with certain electrical systems. They can cause malfunctions and accidents in mines, hospitals, businesses, and homes.

Unfortunately, many lawyers and even engineers are unaware of the potential devastating effects. The cause often goes unnoticed. We cannot see, hear, taste, smell, or feel crosstalk. Additionally, few engineers have the specialized education and experience required to investigate.

Discovery Engineering can handle the most complex crosstalk investigations. Call today for an analysis.

Who Is at Risk?

Any device that has electronic circuitry is susceptible to crosstalk. We use and depend upon electronics every day. Additionally, our electronic devices are increasingly complex and sophisticated. These factors increase the potential risk of EMI and RFI.

The threat of this interference can be minimized by adopting the practices of electromagnetic compatibility (EMC). Call to learn more.
