Nano, MEMS are advancing energy harvesting technology

Using nanotechnology and MEMS technology in energy harvesting applications is a work in progress that nevertheless shows huge potential, experts said.

Progress was in evidence at this week's Sensors Expo here, including a session on using nanotechnology and MEMS in energy harvesting applications. Panelists said companies like EaglePicher, Tadiran and Varta are capitalizing on existing lithium technologies to offer micro batteries for energy harvesting applications.

Jet engine tested at 10 times speed of sound

An experimental jet engine has been successfully tested at speeds of up to 11,000 km (6,835 miles) per hour, or 10 times the speed of sound, during trials in Australia's outback, defense scientists said on Friday.

The experimental scramjet engine is an air-breathing supersonic combustion engine being developed by Australian and U.S. defense scientists that researchers hope will lead to super-high speed flight.

Plastic That Heals Itself

Researchers have developed a new material that can fill in its own surface cracks.
Researchers at the University of Illinois at Urbana-Champaign (UIUC) have made a polymer material that can heal itself repeatedly when it cracks. It's a significant advance toward self-healing medical implants and self-repairing materials for use in airplanes and spacecraft. It could also be used for cooling microprocessors and electronic circuits, and it could pave the way toward plastic coatings that regenerate themselves.

Auditory Nerve Implant Promises Better Hearing

Tiny array placed in auditory nerve may one day offer superior alternative to cochlear implants, U-M animal study suggests.

More than three decades ago, scientists pursued the then-radical idea of implanting tiny electronic hearing devices in the inner ear to help profoundly deaf people. An even bolder alternative that promised superior results — implanting a device directly in the auditory nerve — was set aside as too difficult, given the technology of the day.

MIT cuts the cord

In a perfect world, there'd be no wires. They clutter the view, get tangled behind desks and limit how far networks can reach. That's why the telegraph gave way to the radio. Cell phones unstrung telecommunications. Wi Fi liberated computer data.

Now even the last knotty wire that seemed destined to remain — the power cord — could be on its way out.

Military Target: Solar-Beaming Sats

Last month, a man at a bar introduced himself as "Coyote," and told me he was working on the Pentagon's plans to build a string of satellites that beamed solar rays down to Earth.

My first thought was to call my wife, the psychiatrist.

Wireless energy promise powers up

A clean-cut vision of a future freed from the rat's nest of cables needed to power today's electronic gadgets has come one step closer to reality.
US researchers have successfully tested an experimental system to deliver power to devices without the need for wires.

Potatoes: The Next Plastic?

The usual choices for potatoes include baked, mashed or french fried, but a new study suggests another option: plastic.

A report by the University of Maine's Margaret Chase Smith Policy Center says the state's potato industry could benefit by becoming a producer of bioplastics, which are made from plant starch rather than crude oil and petroleum products.

Web 2.0 Explained

'Field Sense' May Be Teachable

The likes of Wayne Gretzky, Michael Jordan, and Diego Maradona, besides their athletic ability, have an incredible sense of the players around them, which allowed them to display incredible plays in their respective sports.

Peter Vint is a researcher at the US Olympic Committee, and showed Wired his research on how great players quickly adapt to their environments and how this can be taught to others.

Ghost Cities Of 2100

For 900 years, Moenjodaro, a city in what is now Pakistan, was the urban hub of a thriving civilization, the New York or London of its day. Around 1700 B.C., residents suddenly abandoned the Indus Valley city, and it was lost in the sands of time until archaeologists began excavating it in the 1920s.

Today, visitors can wander for hundreds of acres among its deserted streets and homes.

Text messaging could soon be the new way to call for help

Texting on your mobile could soon be the quickest way to call for police help.

The Government has given the go-ahead for a new 999 text-messaging emergency line which will work in tandem with the traditional call centre.

Soon typing in text speak "hlp 5-o sum1 hs brokN n2 my hous" - 'Help police, someone has broken into my house' - should summon an emergency response.

U.S. general laments Google Earth capability

The head of U.S. Air Force intelligence and surveillance on Thursday said data available commercially through online mapping software such as Google Earth posed a danger to security but could not be rolled back.

"To talk about danger is, if I may, really is irrelevant because it's there," said Lt. Gen. David Deptula, deputy chief of staff for intelligence, surveillance and reconnaissance.

Army's Greatest Inventions for 2006

Researchers behind the Army's top 10 greatest inventions for 2006 were recognized recently at a ceremony in Arlington, Virginia. The Army's Greatest Inventions for 2006 are:

Blow Torch Counter Improvised Explosive Device System, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. This vehicle-mounted system detonates IEDs at safe stand-off distances, minimizing vehicle damage and Soldier injuries.

"It's fairly easy to operate, and it gives a sense of security to the Soldiers when they're on convoy duty," said Maj. Brian Hackenberg, who helped develop the system.

Integrated Robotic Explosive Detection System, U.S. Army Aviation and Missile Research, Development and Engineering Center, Redstone Arsenal, Ala. Capable of crossing rugged terrain, this remotely operated system incorporates an explosive trace detector onto a robotic platform.

Plastic Shaped Charge Assembly for Remote Destruction of Buried IEDs, U.S. Army Armament Research, Development and Engineering Center, Picatinny Arsenal, N.J. Remotely emplaced, the PSCA destroys known or suspected unexploded ordnance with higher accuracy than similar devices currently in use. Its low-fragmentation plastic housing eliminates collateral damage.

Humvee Crew Extraction D-ring, U.S. Army Aviation and Missile Research, Development and Engineering Center, Redstone Arsenal, Ala. Combat locks on the up-armored Humvee provide security for Soldiers but often get so damaged the doors can't be opened. The D-ring provides solid anchor points for the hooks of a tow strap, chain or cable to pull open damaged doors.

"There was an issue of Soldiers getting trapped inside Humvees that had been damaged for whatever reason ... enemy fire or being flipped. Soldiers had problems getting the doors off these up-armored Humvees so we took their advice and created the D-ring," said Wesley D. Patterson, who is part of a Fast Assistance in Sciences Team that deploys to help Soldiers solve problems that can be resolved within six months.

M1114 Humvee Interim Fragment Kit 5, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. This kit was fielded as a ballistic improvement for the M1114 Humvee in April 2006. A prototype door solution with fabrication and mounting instructions was provided within one week with automotive testing and safety certification.

Remote Urban Monitoring System, U.S. Army Communications-Electronics Research, Development and Engineering Center, Fort Belvoir, Va. RUMS hardware combines emerging technologies in Wireless Local Area Network technology, night-vision cameras and unattended ground sensors to eliminate false alarms. Tripped sensors transmit an alarm signal to the camera module and operator after video and audio from multiple camera modules confirm the unattended ground sensor's alarm signal.

Constant Hawk, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. Constant Hawk is a surveillance capability that uses an electro-optic payload to collect intelligence and identify areas that require increased surveillance by other assets.

OmniSense Unattended Ground Sensor System, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. OmniSense is an unattended ground sensor system used to detect and classify personnel and vehicles in perimeter defense.

EM113A2 Rapid Entry Vehicle, U.S. Army Armament Research, Development and Engineering Center, Picatinny, N.J. The REV provides rapid entry, non-lethal crowd control and rescue-squad insertion capabilities into areas requiring non-lethal intervention. The vehicle increases Soldier survivability through improved situational awareness and the ability to move and fire from within an armored vehicle.

BuckEye System, U.S. Army Engineer Research and Development Center, Vicksburg, Miss. BuckEye uses a digital camera to produce geospatial information for intelligence, surveillance and reconnaissance. It also produces high-resolution 3D urban mapping.

Chief Warrant Officer 4 Michael Harper said the BuckEye System has been instrumental in allowing a maneuver commander to rapidly map battle space through high-resolution imagery and to collect elevation data to give a 3D view.

"What it gives to Soldiers is added situational awareness they need to fight in an urban terrain," he said. "BuckEye has essentially mapped almost every major city in Iraq thus far."

Turning cars into wireless network nodes

Taking It to the Streets: UCLA Scientists Seek to Turn Cars Into a Mobile Communications Network

It's no secret Americans love their cars, and modern computer systems have enhanced vehicle performance and safety. For computer science professor Mario Gerla and researcher Giovanni Pau at the UCLA Henry Samueli School of Engineering and Applied Science, the next step is to take that digital processing power and push it outward even further — by using cars as computer nodes in a mobile network on wheels.


ONARCHITECTURE- Intelligent design: Will robots take over architecture?


What if a building could build, repair, dismantle, and recycle itself? What if a building were equipped with sensors to track your movement through a space and could adapt its shape, texture, light, sounds, and heat to your presence? Finally, what if you could talk to a building and it could talk back?

Those are the kinds of questions students in UVA architecture professor Jason Johnson's Robotic Ecologies seminar are encouraged to ask and explore.


French Research Agency Validates Flapping Wings for Micro Drone



Flapping wings might be better than rotors for a small surveillance UAV, engineers with the French aerospace research agency ONERA said June 18 at the 47th Paris Air Show.

ONERA’s simulation studies on a third-generation micro air vehicle dubbed Remanta show that such wings used less energy than a mini-helicopter design while delivering speedy flight, hover, endurance and agility, engineers Agnès Luc Boulah and Bruiec Danet said.

The Remanta is a partial demonstrator with a 15-centimeter wing and endurance of around 10 minutes. The micro-drone would fly on a programmed route into confined spaces, perform urban reconnaissance and send imagery for target acquisition and designation. The range would be a few hundred meters and include day/night capability.

Actuators would drive the flapping carbon-fiber wings. The major challenge is finding the power source, which must be compact and deliver 10 to 20 watts. Advances in power cells for mobile phones show promise.

A working demonstrator could be fielded in 10 years, the engineers said.

Labs in Cranfield and Shrivenham in Britain, German researchers and DARPA are also working on flapping wings for micro aerial vehicles.

Homemade Microwave Weapons



The US military is hard at work designing, building, and using directed energy weapons (HERFs -- high energy radio frequency or microwave weapons) for use against micro-electronics and fuel vapor.

Unfortunately, directed energy weapons are much more valuable to global guerrillas than nation-state militaries due to the target imbalance between nation-states and non-state foes. The technology needed to build these weapons is generally available and inexpensive (numerous experiments, including this one, scroll to bottom, with a converted microwave oven demonstrate this).

Homemade directed energy weapons will eventually become the weapon of choice for global guerrillas intent on infrastructure destruction.

Online and offline worlds merge

Google has launched a tool designed to make it easier for computer users to use online applications offline.

One of the key limitations of web services such as e-mail, word processing and calendars, is that they require a net connection to function.


Hi-tech tool tracks city graffiti

US cities are battling the problem of vandalism head on with a hi-tech system that analyses and tracks graffiti and its perpetrators.

In the US, cleaning up graffiti is estimated to cost about $10bn (£5bn) per year. Rather than simply obliterate the graffiti, the system keeps a permanent record of it which allows police to compile a database of similar daubings.

China To Use Computer Viruses As Cyberwarfare First Strike


The Defense Department reports that the People's Liberation Army is moving beyond traditional battlefields and into cyberspace.

The People's Liberation Army in China is building up its cyberwarfare capabilities, even creating malware that could attack enemy computer systems in first-strike attacks, according to a report from the Department of Defense.


A Smarter Web

New technologies will make online search more intelligent--and may even lead to a "Web 3.0."

Last year, Eric Miller, an MIT-affiliated computer scientist, stood on a beach in southern France, watching the sun set, studying a document he'd printed earlier that afternoon. A March rain had begun to fall, and the ink was beginning to smear.

Five years before, he'd agreed to lead a diverse group of researchers working on a project called the Semantic Web, which seeks to give computers the ability--the seeming intelligence--to understand content on the World Wide Web. At the time, he'd made a list of goals, a copy of which he now held in his hand. If he'd achieved those goals, his part of the job was done.

TV Screen: Thin as Paper

In the race for ever-thinner displays for TVs, cell phones and other gadgets, Sony may have developed one to beat them all - a razor-thin display that bends like paper while showing full-color video. Sony Corp. released video of the new 2.5-inch display.

In it, a hand squeezes a display that is 0.3 millimeters, or 0.01 inch, thick. The display shows color images of a bicyclist stuntman and a picturesque lake. Although flat-panel TVs are getting slimmer, a display that's so thin it bends in a human hand marks a breakthrough. Sony said it has yet to decide on commercial products using the technology.

"In the future, it could get wrapped around a lamppost or a person's wrist, even worn as clothing," said Sony spokesman Chisato Kitsukawa. "Perhaps it can be put up like wallpaper."

Can cyborg moths bring down terrorists?

A moth which has a computer chip implanted in it while in the cocoon will enable soldiers to spy on insurgents.

At some point in the not too distant future, a moth will take flight in the hills of northern Pakistan, and flap towards a suspected terrorist training camp.

But this will be no ordinary moth.

Inside it will be a computer chip that was implanted when the creature was still a pupa, in the cocoon, meaning that the moth’s entire nervous system can be controlled remotely.

Mapping Traffic Flow

New trafficking software will enable drivers to find the quickest route to their final destination.

Drivers are always searching for the fastest route--whether they are traveling home on a busy Friday afternoon or rushing to the airport for an early-morning flight. Now Tele Atlas, a Boston-based company that provides digital maps and navigational content, has integrated new trafficking software into its map database so that drivers can find the most optimal route based on speed rather than distance--for any stretch of road at any hour of any day of the week.


New tech may boost indoor mobile coverage


A new technology to boost the indoor coverage of mobile-phone networks — and a possible rival to combined fixed-mobile offerings, such as BT's Fusion — is set to hit the mass market in less than a year, a manufacturer said.


Several companies are developing so-called femtocells, small indoor base stations for third-generation mobile-phone networks, allowing operators to improve indoor coverage at a substantially lower cost than the traditional way of adding more cell towers.


Researchers use gene therapy to restore sight in mice

University of Florida researchers used gene therapy to restore sight in mice with a form of hereditary blindness, a finding that has bearing on many of the most common blinding diseases.

Writing in Nature Medicine, scientists describe how they used a harmless virus to deliver corrective genes to mice with a genetic impairment that robs them of vision.

The discovery shows that it is possible to target and rescue cone cells - the most important cells for visual sharpness and color vision in people.

NATO says urgent need to tackle cyber attack

NATO defense ministers agreed on Thursday that fast action was needed to tackle the threat of "cyber attacks" on key Internet sites after Estonia suffered a wave of assaults on its computer networks last month.

"There was sentiment round the table that urgent work is needed to enhance the ability to protect information systems of critical importance," NATO spokesman James Appathurai told a news conference at a two-day meeting in Brussels.

China won't scrap blog registry

New rules by a Chinese government-backed Internet group maintain strict controls over the country's bloggers, requiring them to register with their real names and identification cards
.

The guidelines from the Internet Society of China (http://www.isc.org.cn), a group made up of China's major Internet companies, contradict state media reports this week claiming that China was considering loosening registration requirements for bloggers to allow anonymous online journaling.

Aerospace companies target young recruits online

Justin Wong, an aerospace engineering student from the Massachusetts Institute of Technology, was schmoozing on Facebook.com last fall when he came across a sleek Boeing job ad.

Wong, who had just interned at the aerospace company, saw the banner on the popular social networking site as a "two-way street" — a defence behemoth reaching out to today's youth in their virtual playground.

"My first impression was that Boeing is getting with the times," said the 21-year-old senior, who will work at Boeing's satellite division after graduation. "It shows the company is making an effort to talk to us on our level."

Backlash against RFID is growing

Civil rights and privacy rights groups have opposed radio frequency identification, or RFID, for years. But now, researchers in the field and some lawmakers are beginning to voice concerns about the security of the technology.

In the past year, twenty-two states have introduced legislation regarding RFID technology, which uses tiny radio transmitter chips, or "tags," that can be inserted in a pallet full of goods, a pair of jeans, or a passport.

New Book: Five minds for the future

New fuel for 21st century -- aluminum pellets?

Pellets made out of aluminum and gallium can produce pure hydrogen when water is poured on them, offering a possible alternative to gasoline-powered engines, U.S. scientists say.

Hydrogen is seen as the ultimate in clean fuels, especially for powering cars, because it emits only water when burned. U.S. President George W. Bush has proclaimed hydrogen to be the fuel of the future, but researchers have not yet found the most efficient way to produce and store hydrogen.


Lasers for video surveillance

Researchers at the Oak Ridge National Laboratory (ORNL) have built a new optical surveillance based on lasers. Their Laser-Based Item Monitoring System (LBIMS) is designed to protect high-value items in high security environments.

It’s also supposed to respect your privacy and be the equivalent of cameras with a 10,000-megapixel resolution. The LBIMS can be used in situations where conventional surveillance systems cannot be employed, such as areas where video surveillance has been specifically prohibited and areas where a RFID system could trigger an explosion. It should become commercially available this year.

A new postal service… from space

In September 2007, the European Space Agency (ESA) will launch its Foton M3 microgravity mission from Baikonur. The spacecraft will carry the Young Engineers' Satellites (YES2) payload.

The goal of this experiment — designed by 500 European students — is to send a 6-kilogram package from space to earth. This spherical parcel, named Fotino, will be attached at the end of a 32-kilometer-long tether. This tether, made of Dyneema, will have a thickness of only 0.4 millimeter. When it's completely deployed at an altitude of about 250 kilometers, it will be cut and Fotino will re-enter the atmosphere to land in Russia, inaugurating the first space postal service.

Faster "slamming" robots

SLAM is an acronym for 'simultaneous localization and mapping,' and slamming robots are simply robots which at the same time build a map of their environment while keeping track of their own localization.

Now, according to New Scientist, Purdue University engineers have designed P-SLAM robots based on a prediction-based SLAM algorithm. This algorithm contains an environmental-structure predictor to predict the structure inside an unexplored region. As these robots make some guesses about their environments, they are able to react faster in unfamiliar buildings. But if this technique is working well in offices — which have some repetitive characteristics from room to room — it is not yet well-adapted to outdoor environments.

A swimming robot — inside your body

The Boston Globe describes the efforts of a Japanese-born scientist to develop new technologies for use in surgery. His last project is to build a swimming robot designed to explore the human gastrointestinal tract (GI tract) from esophagus to colon.

This 2-centimeter long robot will have a swimming tail to deliver the energy picked from the outside and use it to steer it in the GI tract. It will also be able to send back images to the physicians and to deliver therapy. Coincidentally, the Philadelphia Inquirer is reporting about another medical robot helper able to crawl like an inchworm into your heart.

Scientists Create Fire-Safe, Green Plastic

Scientists from the University of Massachusetts Amherst have created a synthetic polymer-a building block of plastics-that doesn't burn, making it an attractive alternative to traditional plastics, many of which are so flammable they are sometimes referred to as "solid gasoline."

The new polymer wouldn't need the flame-retardant chemicals that are added to many plastics before they can be used in bus seats, airplanes, textiles and countless household items. Some of these additives have been showing up in dust in homes and offices, fish, fat cells and breast milk, raising concern that they pose a risk to human health and the environment. (The state of Washington recently banned a class of flame-retardants from use in household items from mattresses to computers-the first state to do so.)


Future of War

Military dictionaries say that what distinguishes war from peace is the massive use of weapons. But today this interpretation is desperately obsolete. The goal of a war of the future will not be to seize enemy territory but to deal surgical strikes against sensitive targets.

International borders are not violated, large-scale use of ground troops and armor is becoming a thing of the past, and the role of strategic aviation is diminished. The traditional nuclear triad is being replaced with non-nuclear high-accuracy weapons with different basing modes.

A Robot Is Built To Rescue Soldiers


U.S. researchers are developing a remote-controlled robot designed to rescue injured or abducted soldiers without putting their comrades at risk. The prototype of the nearly 6-foot-tall Battlefield Extraction-Assist Robot, called Bear, can lift nearly 300 pounds with one arm, and its developer, Vecna Technologies of College Park, Md., is focusing on improving its two-legged lower body.

Naval Robot Wars

A new report drafted by the well-connected Center for Strategic and Budgetary Assessments makes a strong case for an accelerated development of unmanned combat aircraft for carrier battle groups.

With a simple equation, Tom Ehrhard and Robert Work of CSBA lay out the benefits of UCASs for the CVW, saying the increase in range and stealth drones bring to the maritime strike fight are inarguable...


Using technology to enhance humans


It's a well-known fact that technology can improve our lives. For example, we can reach anyone and anywhere with our cellphones. And people who can't walk after an accident now can have smart prosthesis to help them. But what about designing our children on a computer or having a chip inside our brain to answer our email messages? Are we ready for such a future?


In "Robo-quandary," the Milwaukee Journal Sentinel reports that many researchers are working on the subject. And as a professor of neuroscience said, "We can grow neurons on silicone plates; we can make the blind see; the deaf hear; we can read minds." So will all we become cyborgs one day?
