• Nanomaterial in shoes, cloths converts movement into power

    New nanomaterials achieve 80 percent efficiency at converting mechanical energy (as that being generated from walking) into electricity; a single PZT crystal, implanted into a shoe, could theoretically generate 10 milliwatts of power: enough to operate 10 iPods; the goal is to embed the crystals in shoes and cloths of both soldiers and civilians so that the wearer’s movements would power whatever electronic gear he or she carries

  • High school students offer engineering solutions to everyday challenges

    Milwaukee high school participates in Project Lead the Way program, a national curriculum that offers mathematics, science, engineering, and technology education courses to middle and high schools students; students in the program solve everyday problems using engineering technology; they are also mentored by industry insiders, and are encouraged to patent their inventions

  • DHS: New bioterror detector will provide near real-time results

    The BioWatch program now monitors more than 30 U.S. urban areas - 20 more will be added in the near future - for the presence biological pathogens, including anthrax, smallpox, plague, and tularemia; the process of collecting the sensors’ filters and analyzing them takes about 36 hours; DHS says Generation 3 technology will provide near real-time analysis; some experts are skeptical

  • One in four Germans willing to have microchip under skin

    A poll shows one in four Germans would be happy to have a microchip implanted in their body if they derived concrete benefits from it; 5 percent of people said they would be prepared to have an implant to make their shopping go more smoothly

  • U.S. Army looking for robots to extract wounded soldiers from battlefield

    Rescuing wounded soldiers under fire is itself a major cause of military death and injury; the U.S. Army asks inventors to come with idea for a Robotic Combat Casualty Extraction device; the robot should not only be strong and dexterous, but should also be capable of planning an approach and escape route without prior knowledge of the local terrain and geography

  • Robot evaluates safety inside structures

    Researchers develop new method to inspect to interior of dangerous structures — dangerous because of structural damage or because terrorists or criminals are hiding there; a remote-controlled robot that is equipped with an infrared camera and LIDAR (light detection and ranging) technology, which sends out multiple laser points that bounce off objects and provide feedback

  • Smart CCTV detects brush-fire in early stage

    Researchers develop a CCTV that can detect the first flames of a brush fire; a specially developed software for the CCTV analyzes video images for the characteristic flicker and color of a flame; the software looks for pixels which change from one frame to the next, and which also have a fire-like color

  • VTOL, ducted-fan UAV for security monitoring of the London Olympics

    A U.K. company developing a ducted-fan, VTOL UAV says the ability of the vehicle to take off vertically and maneuver around the tops of buildings would make it ideal for security monitoring at the London Olympics and other urban law-enforcement mission; the U.K. start-up says that compared to other UAVs, the Flying Wing can work more aptly against wind gusts, making it suitable for helping troops in mountainous Afghanistan

  • Israel unveils world's largest UAV

    The Eitan is 79 feet long, has a wingspan of 86 feet — about the size of a Boeing 737 airliner — and can stay aloft for 20 hours at high altitude; powered by a 1,200-horsepower turbojet engine, it has a maximum altitude of 40,000 feet and can carry hundreds of pounds of equipment, such as high-resolution cameras and electronic systems and presumably weapons; Israel says the UAV has the capability of reaching the Gulf

  • Intellectual Ventures: A genuine path breaker or a patent troll?

    Intellectual Ventured has amassed 30,000 patents, spent more than $1 million on lobbying last year, and its executives have contributed more than $1 million to Democratic and Republican candidates and committees; the company says it wants to build a robust, efficient market for “invention capital”; critics charge that some of its practices are closer to that of a patent troll

  • Killing malaria bugs dead with laser

    Mosquito-killing laser demonstrated; if bed nets are the low-tech solution to combat the deadly malaria — caused by a parasite transmitted when certain mosquitoes bite people — the laser is a high-tech one; the laser detection is so precise, it can specify the species, and even the gender, of the mosquito being targeted

  • New fiber nanogenerators could lead to electric clothing

    UC Berkeley researchers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles; these nano-sized generators have “piezoelectric” properties that allow them to convert into electricity the energy created through mechanical stress, stretches, and twists

  • New technologies unveiled to protect U.K. 75 million mobile phone users from crime

    U.K. e-commerce, or contatcless, mobile transactions, will account for £151 billion by 2013. the U.K. government’s Design Council unveils three solutions aiming to make mobile phones – and, hence, e-commerce – safer

  • Oak Ridge develops powerful intrusion detection systems

    The attack analysis program uses machine learning to increase effectiveness; ORCA effectively sits on top of off-the-shelf intrusion detection systems, and its correlation engine processes information and learns as cyberevents arrive; the correlation engine supplements or replaces the preset rules used by most intrusion detection systems to detect attacks or other malicious events

  • Revolutionary water treatment system may make coping with disaster easier

    Researchers develop a revolutionary waste-water treatment device which uses little energy, is transportable, scalable, simple to set-up, simple to operate, comes on-line in record time, and can be monitored remotely; new system cleans influent wastewater within twenty-four hours after set-up to discharge levels that exceed the standards established by the Environmental Protection Agency (EPA) for municipal wastewater
