Electromagnetic system to replace steam launches on US Navy carriers

A fighter plane taking off from a strike carrier is a dramatic sight – not the least because of the woosh and plume of steam as the catapult blasts the aircraft into the air. In a few years, such launches may still be dramatic, but they’ll also be a bit quieter and very plume-free. That’s because the US Navy has completed testing of its Electromagnetic Aircraft Launch System (EMALS); clearing it for use on the new Gerald R Ford-class aircraft carriers.Read More

Exelis tests versatile new airborne sensor for explosives and dangerous chemicals

Hyperspectral imaging is a bit like super-vision. With it, you can not only see what’s there, but what it’s made of, which is a good thing if you’re looking for bombs, gas leaks, and smuggled nuclear material. Defense and information systems specialist Exelis has announced the successful test of a new airborne long-wave infrared (LWIR), hyperspectral (HSI) sensor that can be aimed in multiple directions and is capable of detecting explosives, gases and dangerous chemicals.Read More

Lunecase harvests electromagnetic energy from iPhone to power LED alerts

Smartphone cases are so common that you can pick one up at the supermarket checkout stand, so for one to stand out, it needs something more than a print of a cartoon kitten. Built by Concepter, a company based in Kiev, Ukraine, the Lunecase is s a batteryless, wireless phone case that not only interacts with an iPhone, but also powers itself from the electromagnetic radiation emitted by the device.Read More

BAE Systems develops a flat lens that acts like it's curved

Anyone who’s ever needed a pair of thick eyeglasses has a firm idea that lenses are the one thing where form follows function. However, BAE Systems and Queen Mary’s School of Electronic Engineering and Computer Science in London have put paid to that idea with a flat lens that works like a conventional curved lens, yet without any reduction in bandwidth performance. Using a combination of composite metamaterials and transformational optics for the first time, they have created a lens that's able to bend electromagnetic waves, yet isn't bound by its shape for its function.

Cefaly migraine prevention headband gets FDA approval

Though using electrical stimulation of the brain as a means of treating migraines has provided an alternative to over-the-counter medication, the administering of the electrical currents can be complex, involving bulky equipment or even surgically implanted electrodes. Cefaly, a battery-operated headband, has now been approved by FDA (US Food and Drug Administration) and is said to not only treat migraines, but possibly prevent them altogether. Read More

Electromagnetic Levitator headed to ISS for future materials research

Astronauts, get your welding goggles on – the space station is going into the foundry business. The International Space Station is set to do a spot of industrial research this June, when ESA’s Materials Science Laboratory-Electromagnetic Levitator heads for the station aboard Europe's’ ATV-5 Georges Lemaître unmanned space freighter as part of a program to study the casting of alloys in a weightless environment.Read More
