Bing Dips Toe Into Real-Time Search With Twitter Tie-In
Search engines generally take their time in getting recently posted content into their search databases. Bing, Microsoft's new search engine, is making a push toward real-time search capabilities by roping in just-tweeted Twitter posts from a smattering of celebrities and well-known techies. The content, of course, will be tied to advertising.

Apple Files Touchscreen-Related Patent Applications
Apple may be developing technology that would provide non-visual feedback when a person touches the screen of a laptop, smartphone, or other electronic device, according to a patent application filed by the company Thursday.
Such technology could fix one of the biggest complaints of the iPhone's virtual keyboard, which is the lack of any non-visual response. The haptic response could be in the form of a vibration and paired with an audible noise, the document filed with the U.S. Patent & Trademark Office says.

WiMax Ready To Surge Again
The roaring deployment of WiMax equipment rollout is expected to pause for a few months, then take off again by the end of the year, according to a report from Infonetics Research.
The rapid growth of the wide-area technology has been slowed by the worldwide economic meltdown, but also appears to have been influenced by a simple need to reorganize after its earlier soaring growth, the market research firm said as it released its quarterly report on mobile infrastructure this week.

First Flight of Land-Based MQ-8B Fire Scout
A Northrop Grumman Corporation MQ-8B Fire Scout Vertical Unmanned Aircraft System (VUAS), designated P7, has successfully completed first flight operations at Yuma Proving Grounds, Ariz. Unlike current Navy configured Fire Scouts, P7 was built in an operational land-based configuration.
It is the first MQ-8B to fly without flight test instrumentation normally installed for developmental flights, a clear indication of MQ-8B's system maturity. P7 continues Northrop Grumman's commitment to customers around the globe by building upon the rigorous developmental testing being supported by P6, the first company owned Fire Scout.

Hard disk or solid-state?
Though solid-state drives are in vogue, market forces and technical issues are giving the venerable hard-disk drive new life.
DRAMexchange, a Taipei-based market intelligence firm, said last week that the adoption of solid-state drives by computer vendors has slowed as the price of the NAND chips--the raw material of solid-state drives--has increased. The firm also said that computer makers have been cautious about using solid-state drives because current Windows operating systems are not fully optimized for SSDs.

Synthetic Fuels Move Toward Acceptance
The possibility of commercially available synthetic jet fuels took a step closer to reality last week when ASTM International’s aviation fuels subcommittee passed a new specification for alternative jet fuel. The new specification details the properties and criteria required to control the production and quality of synthetic fuels for aviation use.

Boeing Team to Develop Revolutionary Spacecraft Power System
DARPA's FAST program aims to develop a new, ultra-lightweight High Power Generation System (HPGS) that can generate up to 175 kilowatts -- more power than is currently available to the International Space Station. When combined with electric propulsion, FAST will form the foundation for future self-deployed, high-mobility spacecraft to perform ultra-high-power communications, space radar, satellite transfer and servicing missions.

Alternative armour
A textile-based protection system designed to replace bar and slat armour could provide the UK military with a new level of defence against rocket-propelled grenade attacks.
Resembling a mattress, the lightweight Tarian system is currently being used on a number of Heavy Equipment Transporters in Afghanistan. AmSafe Bridport, the Dorset-based company that designed the system, claimed it is seven times lighter than traditional steel armour and 50 per cent lighter than aluminium.

Beam shaping improves diode-laser performance
While high-power diode lasers are attractive for applications in which size and efficiency matter, other inherent characteristics have limited their use. Now the European Space Agency has demonstrated that design detail and beam correction can enable these devices to deliver efficient illumination with superior brightness.

Fleets Turn to Small Ships for New Conflicts
During a speech at the U.S. Naval War College in April, Defense Secretary Robert M. Gates cited the value of developing a viable force of small warships that are better suited to face current threats in the littorals than vessels designed for blue-water operations.
“You don’t necessarily need a billion-dollar ship to chase down a bunch of teenaged pirates,” he told a group of Navy officers. “The size of the ship in such cases is less important than having Navy Seals on board. To carry out the missions we may face in the future—whether dealing with non-state actors at sea or near shore, or swarming speedboats—we will need numbers, speed and ability to operate in shallow waters.”
