A team of scientists from the Harbin Institute of Technology proposed a new spaceship antenna to prevent space communication blackouts. The group’s research has been published in the Journal of Applied Physics. The new antenna can prevent communication blackouts in space when spacecraft are coming back into Earth’s atmosphere. “The proposed technique can maintain … [Read more...]
‘Pregnant Women’ Wi-Fi Router Setting Causes Debate in China
Two Chinese tech firms, Qihoo 360 and Xiaomi, have quarreled over a wireless router with a unique setting for pregnant women. The two firms are intense rivals and have both recently released new products. Qihoo 360 released the wireless router that is currently at the center of controversy. The router has three settings: wall penetration, balance and pregnant women. The … [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...]
Saharan Ants Control Electromagnetic Waves to Stay Cool
A joint project conducted by Columbia University, The University of Washington and the University of Zürich indicates how Saharan Silver Ants stay cool in one of the hottest climates in the world. The team’s research paper titled ‘Saharan Silver Ants Keep Cool by Combining Enhanced Optical Reflection and Radiative Heat Dissipation’ was recently published in Science … [Read more...]
Defense Contractor to Produce Electromagnetic Aircraft Launch System
General Atomics, a defense contractor in San Diego, Calif., announced it will produce the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for the John F. Kennedy aircraft carrier under a contract from the U.S. Navy. The EMALS system uses bursts of electromagnetic energy to launch planes and jets into the air. It takes up less space on ships, … [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...]
NASA Developing Early Warning System for Solar Flares
NASA has announced it is developing an early warning system for solar flares to give the Earth more time to prepare for storms, thus reducing damage. Scientists from both NASA’s Goddard Space Flight Center and Imperial College London published their research and experiments in Space Weather in the June 9 edition. Their research demonstrates how the new warning system can both … [Read more...]
Fluid Operated Computer uses Electromagnetic Fields to Perform Operations
A group of engineers from Stanford University have produced the first ever water operated computer. The computer uses electromagnetic fields to pump water droplets impregnated with magnetic nanoparticles into gates to perform complex logical operations. Manu Prakash, a Stanford assistant professor, spent almost an entire decade thinking about the possibility of a … [Read more...]
