Researchers use inkjet acumen to create wireless explosive sensor from paper

Posted in: military, prototype, research, sensor, Today's Chili
Meet Krishna Naishadham and Xiaojuan (Judy) Song. They’re researchers at the Georgia Institute of Technology, and those little devices they’re holding may one day save you from an explosive device. This petite prototype is actually a paper-like wireless sensor that was printed using basic inkjet technology, developed by professor Manos Tentzeris. Its integrated lightweight antenna allows the sensor to link up with communication devices, while its functionalized carbon nanotubes enable it to pick up on even the slightest traces of ammonia — an ingredient common to most IEDs. According to Tentzeris, the trick to such inkjet printing lies in the development of “inks” that can be deposited at relatively low temperatures. These inks, laced with silver nanoparticles, can then be uniformly distributed across paper-based components using a process called sonication. The result is a low-cost component that can adhere to just about any surface. The wireless sensor, meanwhile, requires comparatively low amounts of power, and could allow users to detect bombs from a safe distance. Naishadham says his team’s device is geared toward military officials, humanitarian workers or any other bomb sniffers in hazardous situations, though there’s no word yet on when it could enter the market. To find out more, careen past the break for the full PR.

How Stealth Works

Posted in: military, Today's Chili, top

Stealth bombers are not invisible—far from it, in fact. The Northrop Grumman-designed B-2 Spirit has a hard-to-ignore 175-foot wingspan and a thin, disk-like silhouette that makes it look like a cross between a stingray and an alien craft from a summer blockbuster. More »

Mesa Robotics’ mini-tank is perfectly happy on point (video)

Posted in: military, robotics, Today's Chili, video, wargadget

The Acer ground-bot from Mesa Robotics does way more than your average 4,500-pound semi-autonomous mule. In addition to carrying kit and providing that extra bit of ballistic steel-deflecting cover, it also scans for IEDs using ground-penetrating radar and then autonomously switches into “flail” mode when it finds one — digging up and detonating that critter with barely a break in its 6MPH stride. Did we mention it also acts as a landing pad for small drones? No? That’s because the video after the break says it all. Cue obligatory guitars, game controllers and armchair gung-ho.

Flight sim bubble offers 360-degree view, makes earth seem round

Posted in: military, projector, Today's Chili

You’ve got the yoke, you’ve got the ridiculously over-priced gaming chair, so now all you need is Barco’s 360-degree display dome. It uses 13 separate projectors to create a hi-def simulacrum of paradise inside a 3.4-meter acrylic sphere. The pilot sits in the middle, suddenly remembers why he took up aviation, and then connects with up to seven other bubbles to practice complicated squadron missions. More desperately inviting pics after the break.

IEE brings glasses-free 3D to the battlefield

Posted in: military, Today's Chili, wargadget
In a war zone, having the right data is as important as the right bomb sniffing laser. IEE has melded its 4.8-inch 800 x 400 military data display with 3Ms autostereoscopic film so soldiers can see mission-critical data in three dimensions. The Preliminary Advanced Information device is designed to show accurate terrain maps, relay the picture from a drone camera or bring up the occasional blast of Monday Night Football.

Giant tablet lets commanders control war with the swipe of a finger

Posted in: military, slate, tablet, Today's Chili, wargadget

America’s armed forces have added some major tech to their arsenal lately, from smartphones for soldiers to giant surveillance blimps. And now, AAI has unveiled a new tool for battlefield commanders in the form of giant touchscreen tablet. Its screen is three feet by two feet and employs surveillance information to give those in charge an overhead view of a war zone that shows the position of both good guys and bad. Icons represent troops, air support, and spy drones, which are then deployed by tapping and dragging them on the touchscreen. Such input doesn’t actually control battlefield assets, but it does send orders to the appropriate personnel so they can be executed, and soldiers confirm receipt of the order via instant message. The company’s still trying to sell the system to the Army, but we’d imagine that such drag and drop warfare will appeal to Uncle Sam. Who knows, perhaps all those hours spent honing your Starcraft skills can soon be put to good use defending the country.

ITT unveils GhostRider encryption device capable of securing US Army smartphones

Posted in: Android, military, motorola, operating system, OperatingSystem, os, phone, security, smartphone, Today's Chili, ui, wargadget
That may look like a Motorola Atrix, but it’s actually something known as the GhostRider — a new encryption device that could go a long way toward securing the Army’s smartphones. Developed by defense company ITT, this revamped handset would allow military personnel to transmit secure text messages and phone calls over the Army’s network, even if they’re out on the battlefield. All they’d have to do is place their personal phones next to the GhostRider, tap and hold its touchscreen to activate the security features and begin texting away. When another GhostRider user receives an SMS, he or she would have to enter a pass code before reading it. The phone’s security mechanisms, meanwhile, have been certified by the cryptographers at the NSA, which would certainly help justify its $1,500 price tag. The handset’s display, meanwhile, looks awfully similar to the Army’s Nett Warrior platform — an Android-based OS that features a host of mapping functions designed explicitly for war zones. Officials unveiled the latest incarnation of Nett Warrior at the recent Association of the US Army gala in DC, though the platform’s creators are still looking for the appropriate commercial device to host it — unless, of course, GhostRider’s software replaces it altogether. “We think Nett Warrior should be something like this,” ITT vice president Richard Takahashi told Wired. “This can be the smart device.” March past the break for more information, in ITT’s jargon-laced PR.

Raytheon shows off TransTalk speech translator for Android, hopes to find a home in the Army’s app store

Posted in: Android, military, mobilepostcross, Today's Chili
We’ve already heard about some of the smartphone apps that may or may not eventually find their way into the Army’s own app store, and Raytheon is now hoping that it’ll be tapped it to provide a key one. As Wired’s Danger Room reports, the company has developed a new version of its TransTalk app for Android phones, which is able to translate speech from English to Arabic, Dari and Pashto (and vice versa). Since it’s designed specifically for the Army, the app is geared towards translating phrases commonly used by soldiers on patrol, and it’s also able to display and store the conversation as text. Just don’t count on it hitting the Android Market anytime soon — while the app runs on off-the-shelf Android hardware (a Motorola Atrix, in this case), there’s no plans for it to be made available to the general public.

This giant military spy blimp is really hard to miss

Posted in: laser, military, minipost, Today's Chili, wargadget
What’s this spy blimp doing next to an 18-wheeler? We’re not entirely sure, but it’s certainly not being subtle about it. This jumbo-sized floater, codenamed “Blue Devil Block 2,” measures some 370 feet in length and comprises a whopping 1.4 million cubic feet. Originally inflated in September, the definitely-not-blue Blue Devil took flight for the first time last week in North Carolina and, if all goes to plan, should head to Afghanistan by the middle of next year. The Air Force says the blimp will hover above the country for five days at a time, collecting surveillance data from 20,000 feet above the ground and transmitting its findings to US intelligence officers on the ground, via laser. When that’s taken care of, it’ll be used to make the biggest omelette ever.

How the Nazis Sunk the Largest Underwater Treasure In the World

It was a dark, ice-cold February. The merchant ship SS Gairsoppa was seeking refuge in Ireland when a Nazi U-boat sunk her. She was loaded with seven million ounces of silver. That’s worth $202.74 million in today’s dollars. More »
