Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]
Canadian Police to Receive New Radio System after EMI Issues
Sault Ste. Marie Police are preparing for a new radio system, since their current system, which is 15 years old, experiences communication problems and constant radio frequency interference. However, police dispatchers still have problems ahead. “Motorola is phasing out support the console's main components. The withdrawal of assistance starts in 2016 and ends in 2018,” … [Read more...]
‘Radiogate’ Controversy in First NFL Game – Pittsburgh Experienced EMI in Helmets
Last night, during the NFL season opener in New England between the New England Patriots and the Pittsburgh Steelers, a technology malfunction reportedly caused the Patriot’s radio broadcast to air on the headsets of the Steelers’ coaches during the entire first half of the game. The nickname ‘Radiogate’ has surfaced – a play on the Patriot’s previous ‘Deflategate’ controversy … [Read more...]
SMD Ferrites Expanded; Company to Showcase EMC Components at Symposium
Würth Elektronik eiSos GmbH & Co. KG will showcase its new range of SMD ferrites, known as the WE-MPSB-SMD Ferrites, at the IEEE EMC Symposium in Dresden. The SMD ferrites are suitable for temporary peak current loads and for use in power supply lines. They can withstand 20 times their specified rated current load – which is 55 percent higher than other components on the … [Read more...]

Canted Coil Catalog Describes Benefits for EMI/RFI Shielding
Bal Seal Engineering, Inc. released a new 10-page catalog that describes the benefits of canted coil springs for EMI/RFI Shielding. It “provides engineers and designers with detailed information about how canted coil springs can be used to address electromagnetic interference/radio-frequency interference (EMI/RFI) shielding challenges. It describes how the compact, … [Read more...]
Energy-efficient Electric Car: No AM Radio Due to Possible EMI
The BMW i3 Electric Car was the most energy-efficient car sold in the U.S. this year, according to Green Car Reports. However, consumers noticed the car does not offer AM Radio. “AM is not offered due to negative performance influences of the electromagnetic interference of the electric drivetrain. Electric motors cause interference on AM which is why BMW decided to remove … [Read more...]
EMI from Smartphones May Affect Cardiac Devices
Dr. Carsten Lennerz, cardiology resident in Germany, presented results of a study on Monday at the European Heart Rhythm Association (EHRA) Eurospace Cardiostim. “Pacemakers can mistakenly detect electromagnetic interference (EMI) from smartphones as a cardiac signal, causing them to briefly stop working. This leads to a pause in the cardiac rhythm of the pacing dependent … [Read more...]
Military Radio Frequencies May Interfere with Garage Door Openers
Remote-control garage door openers near the Blue Grass Army Depot in Richmond K.Y. may stop working due to military radio systems switching to a new frequency range. The U.S. military will switch all land mobile radios (LMRs) to new frequencies, which are also the same frequencies used by certain unlicensed consumer devices, like garage door openers. These frequencies have … [Read more...]
Radio Interference May Cause Malfunction in Amtrak’s New Anti-crash System
Amtrak is working on an anti-crash system to prevent high-speed derailments, like the fatal derailment in Philadelphia P.A. last month that killed eight passengers, injured hundreds and caused more than $9.2 million worth of damages. However, the anti-crash system may malfunction near freight railroads. Radio interference from freight rails may disable Amtrak’s anti-crash … [Read more...]
