Naval Exercise Causes Mobile Phone Black Spot

 

Plymouth Sound, a bay in England, lost mobile phone signal during a naval exercise last week. The navy said it was testing new ‘communication equipment’ when a mobile phone black spot occurred in the PL1 and PL2 postcodes. Local residents made numerous complains to mobile network operators and as a result, Ofcom, the communications regulator in the United Kingdom, is … [Read more...]

Multilayer Ceramic Capacitor Increases Capacitance by 50 Percent

 

The first commercially available X5R/X6S 330μF multilayer ceramic capacitor has been produced by TAIYO YUDEN. Compared to the previous products, in the same size capacitor, capacitance increases by more than 50 percent. This capacitor was designed to replace electrolytic capacitors and to reduce noise and smooth ripple current in power supply circuits. It offers longer product … [Read more...]

Physicists Discover Graphene Absorbs up to 50 Percent of Microwave Radiation

 

A team of physicists from the University of Namur in Belgium have discovered that graphene serves as an effective shield against microwave inference. Graphene has the ability to reduce microwave pollution and to enhance the electromagnetic compatibility of future electronic devices. Philippe Lambin, project lead, and and his colleagues demonstrated that “the conductivity of … [Read more...]

U.S. Navy Tests Electromagnetic Catapult

 

Traditional steam-powered catapults assist aircraft carriers’ jets and bombers in getting off the ground as quick as possible on a short runway. The U.S. Navy is now testing an electromagnetic version of a catapult on the 337-metre long USS Gerald R. Ford aircraft carrier. “The Electromagnetic Aircraft Launch System (EMALS) uses a burst of electromagnetic energy to launch … [Read more...]

New Bill Could Affect Road Safety Technology

 

The U.S. government says Wi-Fi contributes to more than $140 billion of economic activity per year and demand is growing for the limited available spectrum, according to CBS news. A new bill has been drafted to fix this problem. Lawmakers plan to open a Wi-Fi space for the public; however, it could negatively impact vehicle-to-vehicle commutation (V2V) technology, which … [Read more...]
