DARPA Funds a $300 Software-Defined Radio For Hackers

Sparrowvsrevolution writes with this story from Forbes: “Over the weekend at the ToorCon hacker conference in San Diego, Michael Ossmann of Great Scott Gadgets revealed a beta version of the HackRF Jawbreaker, the latest model of the wireless Swiss-army knife tools known as ‘software-defined radios.’ Like any software-defined radio, the HackRF can shift between different frequencies as easily as a computer switches between applications–It can both read and transmit signals from 100 megahertz to 6 gigahertz, intercepting or reproducing frequencies used by everything from FM radios to police communications to garage door openers to WiFi and GSM to next-generation air traffic control system messages. At Ossmann’s target price of $300, the versatile, open-source devices would cost less than half as much as currently existing software-defined radios with the same capabilities. And to fund the beta testing phase of HackRF, the Department of Defense research arm known as the Defense Advanced Research Projects Agency (DARPA) pitched in $200,000 last February as part of its Cyber Fast Track program.”

DARPA Creates Machine Which Extinguishes Fires With Sound

July 15th, 2012 07:04 admin View Comments

Science

SchrodingerZ writes “The Defense Advanced Research Projects Agency (DARPA) is known for making odd scientific advances ranging from hypersonic unnamed rockets to bionic prosthetic limbs to insect-sized reconnaissance drones. But recently DARPA has made a interesting advancement in the field of fire suppression. Using two speakers arranged on either side of an open liquid fuel flame, an acoustic field was emitted and engulfed the fire. ‘The sound increases air velocity, which then thins the area of the flame where combustion occurs, known as the flame boundary.’ This make the flame weak and much easier to douse. Another wonderful thing about this, its not even that loud! DARPA began its testing in 2008, stating that despite extensive research in this area, there have been no new methods for extinguishing and/or manipulating fire in almost 50 years. The agency plans to expand on this experiment and try to make it successful on a practical scale.”

Gigapixel Camera Catches the Small Details

Technology

An anonymous reader sends this quote from Nature: “David Brady, an engineer at Duke University in Durham, North Carolina, and his colleagues are developing the AWARE-2 camera with funding from the United States Defence Advanced Research Projects Agency (abstract). The camera’s earliest use will probably be in automated military surveillance systems, but its creators hope eventually to make the technology available to researchers, media companies and consumers. … AWARE-2 sidesteps the size issue by using 98 microcameras, each with a 14-megapixel sensor, grouped around a shared spherical lens. Together, they take in a field of view 120 degrees wide and 50 degrees tall. With all the packaging, data-processing electronics and cooling systems, the entire camera is about 0.75 by 0.75 by 0.5 metres in volume. The current version of the camera can take images of about one gigapixel; by adding more microcameras, the researchers expect eventually to reach about 50 gigapixels. Each microcamera runs autofocus and exposure algorithms independently, so that every part of the image — near or far, bright or dark — is visible in the final result. Image processing is used to stitch together the 98 sub-images into a single large one at the rate of three frames per minute.”

DARPA Aims To Reuse Space Junk

ISS

CowboyRobot writes “Space junk has increased to the point where pieces of it are colliding and breaking into smaller pieces. The problem is now so bad that NASA has had to modify the design of satellites to protect them from flying debris. The Defense Advanced Research Projects Agency (DARPA) wants to turn disabled satellites and their components, including antennas and solar arrays, into functioning systems. They are hosting a conference on June 26 to explore how to build ‘refurbished’ satellites from already-orbiting material for less than what it would cost to build them from scratch and launch them from the surface of the Earth.”

Pentagon Wants Disposable War Satellites

The Military

Hugh Pickens writes “BBC reports that the Pentagon’s Defense Advanced Research Projects Agency (DARPA) has invited manufacturers to propose squads of disposable mini-satellites costing about $500,000 each, capable of providing reconnaissance to soldiers at the press of a button. ‘We envision a constellation of small satellites, at a fraction of the cost of airborne systems, that would allow deployed warfighters to hit “see me” on existing handheld devices and in less than 90 minutes receive a satellite image of their precise location to aid in mission planning,’ says the agency. The U.S. Army already has access to drone aircraft to provide intelligence from the skies, and last year they announced that new helicopter-style machines equipped with 1.8 gigapixel cameras will soon go into service in Afghanistan. However, DARPA says such unmanned aircraft cannot cover extended territory without frequent refuelling. The SeeMe constellation will consist of some two-dozen satellites, each lasting 60-90 days in a very low-earth orbit before de-orbiting and completely burning up, leaving no space debris and causing no re-entry hazard. ‘With a SeeMe constellation, we hope to directly support warfighters in multiple deployed overseas locations simultaneously with no logistics or maintenance costs beyond the warfighters’ handhelds,’ says program manager Dave Barnhart.”

US Wants Natural Gas As Major Auto Fuel Option

Government

coondoggie writes “Natural gas has never been much of an option for U.S. car drivers, and it’s going to take a lot of effort by the government and auto manufacturers to make it a viable alternative to gas. But that’s just what a $10 million program from the Department of Energy’s advanced project development group The Advanced Research Projects Agency — Energy (ARPA-E) aims to start anyway. ARPA-E’s Methane Opportunities for Vehicular Energy (MOVE) program wants to develop system ‘that could enable natural gas vehicles with on-board storage and at-home refueling with a five-year payback or upfront cost differential of $2,000, which excludes the balance of system and installation costs.’”

Pentagon To Crowdsource Weapons Software Testing

The Military

An anonymous reader writes “The Pentagon plans to fork over $32 million to develop ‘fun to play’ computer games that can refine the way weapons systems are tested to ensure they are free from software errors and security bugs, according to a Defense Department solicitation. The goal is to create puzzles that are “intuitively understandable by ordinary people” and could be solved on laptops, smartphones, tablets and consoles. The games’ solutions will be collected into a database and used to improve methods for analyzing software, according to the draft request for proposals put out by the military’s venture capital and research arm, the Defense Advanced Research Projects Agency.”

DARPA Wants To Get Rid of Password Protection

coondoggie writes “Researchers from the Defense Advanced Research Projects Agency will next week detail a new program it hopes will develop technology to dramatically change computer system security authorization. The program, called Active Authentication, looks to develop technology that goes way beyond today’s use of hard to remember password protection and determine identity through ‘use of software applications that can determine identity through the activities the user normally performs,’ DARPA said.”
