In an effort to reevaluate the use of portable electronic devices (PEDs) during flight, the Federal Aviation Administration (FAA) has requested comments from aircraft operators, pilots, PED manufacturers and PED designers on the current regulations in place. Though the FAA notes in their request that some devices do not transmit or receive any signals, they may still generate … [Read more...]
Integrated Circuits for EMI Reduction of Clock Dependent Signals
ON Semiconductor, a supplier of silicon solutions for energy efficient electronics has introduced a new series of active spread spectrum clock generator integrated circuits (ICs) to manage electromagnetic interference (EMI) and radio frequency interference (RFI) and deliver “system-wide EMI reduction of all clock dependent signals.” According to Ryan Cameron, vice president of … [Read more...]
Pennsylvania Voting Machine Malfunction EMI Related?
The recent election night proved to be a test for even the most determined voters. In addition to the long, slow-moving polling lines and the haphazard solutions put hastily into place for hurricane-ravaged areas of the Northeast, voters were also subjected to electronic voting machine malfunctions in several states across the country. In Pennsylvania, a voting machine was … [Read more...]
World's Tallest Broadcast Tower Experiences Interference
The world’s tallest broadcast tower, the 634 meter Tokyo Skytree, has experienced unanticipated radio interference, despite being twice the height of the next tallest tower in Tokyo - Tokyo Tower. The Sky Tree was completed in May 2012. The transfer of radio wave transmission from Tokyo Tower to Tokyo Skytree was originally planned for January 2013 but has been delayed because … [Read more...]
New Research Suggests Monolayer Graphene is Most Effective Material for EMI Shielding
Scientists have discovered that ultra-lightweight carbon nanostructure-based nanocomposite materials outperform conventional metal shielding due to their lighter weight, cost efficiency, flexibility and resistance to corrosion. The research is an attempt to overcome the weight issue of traditional metal-based EMI shielding in electronic devices in order to produce smaller and … [Read more...]
Debate Over Harmful Effects of Radio Waves Continues
Though the level of general concern about possible harmful effects from radio frequency radiation given off by mobile phones, wireless networks and smart meters has decreased in recent years, a small percentage of the population remains convinced that the electromagnetic radiation from wireless technology is dangerous. Patients with one condition, electromagnetic … [Read more...]
