Some smartphones are starting to incorporate 3-D gesture sensing based on cameras, but cameras consume significant battery power and require a clear view of the user’s hands. Univ. of Washington engineers have developed a new form of low-power wireless sensing technology that could soon contribute to gesture control by letting users “train” their smartphones to recognize and respond to specific hand gestures near the phone.
Technology being honed by French auto parts maker Valeo uses a dozen ultrasonic sound-wave sensors, 360-degree cameras and a laser scanner to safely park within a few centimeters of other vehicles. Then, when you're done with dinner or a business meeting, the car will return to you after another swipe of the thumb.
Engineers have created a shape-changing "soft" robot that can tread over a variety of adverse environmental conditions including snow, puddles of water, flames, and the crushing force of being run over by an automobile. The pneumatically powered, fully untethered robot was enabled by the careful selection of materials and composites, including silicone elastomer.
Researchers have designed a single molecule which can act as a useful building block in nanometer-size circuits. They found that the molecule functions as a resonant tunneling device, an essential component in mobile phones and WiFi. These devices typically have a complicated design consisting of several layers of different materials.
Researchers in Switzerland have created an Android app which lets users get together to crack a modern cryptographic code. Building on earlier work that used a network of 300 PlayStation consoles, the scientists decided to leverage the power of smartphones. By running the algorithm a very large number of times the code may be broken eventually.
Wireless technology is already widespread in the research laboratory and industrial settings, where solutions are supported by WiFi and the advent of smartphones and tablets. Dedicated wireless platforms for scientific instruments, however, are more unusual. The reason for this is economies of scale.
In 2006, DARPA launched a long-term project called CORONET, which sought to develop a cloud-based technology that could enable affordable, fast bandwidth and ensure the survival of cloud networks in the event of system-wide failures. After years of work, scientists from AT&T, IBM and Applied Communication Sciences have announced a proof-of-concept technology that reduces setup times for cloud-to-cloud connectivity from days to seconds.
A research team in Illinois has built a new type of tunable nanoscale antenna that could facilitate optomechanical systems that actuate mechanical motion through plasmonic field enhancements. The team’s fabrication process shows for the first time an innovative way of fabricating plasmonic nanoantenna structures under a scanning electron microscope, which avoids complications from conventional lithography techniques.
Lighting is crucial to the art of photography, but they are cumbersome and difficult to use properly. Researchers at Massachusetts Institute of Technology and Cornell Univ. aim to change that by providing photographers with squadrons of small, light-equipped autonomous robots that automatically assume the positions necessary to produce lighting effects specified through a simple, intuitive, camera-mounted interface.
A Brown Univ. group has developed a wireless virtual reality system to study a phenomenon that scientists don’t yet understand: How pedestrians interact with each other and how those individual behaviors, in turn, generate patterns of crowd movement. The system, which uses motion capture technology can immerse up to four people in a carefully controlled, realistic virtual crowd.
Altera Corp. of California and Lime Microsystems, a radio frequency transceiver developer in the U.K. have entered into a Strategic Cooperation Agreement focused on jointly developing and promoting programmable solutions for a diverse range of broadband wireless markets. The agreement will result in the development of optimized field programmable radio frequency (FPRF) transceivers and other digital RF solutions.
One might be hidden in a cross on a church lawn. Others are disguised as a cactus in the desert, a silo in farm country or a palm tree reaching into a sunny sky. Whatever the deception, the goal is the same: concealing the tall, slender cellphone towers that most Americans need but few want to see erected in their neighborhoods.
In early March, a mysterious ship the size of a large passenger ferry left Romania and plotted a course toward Scandinavia. About a month later, at the fenced-in headquarters of Norway's military intelligence service, the country's spychief disclosed its identity. It was a $250 million spy ship, tentatively named Marjata, that will be equipped with sensors and other technology to snoop on Russia's activities in the Arctic beginning in 2016.
HorseFly has eight rotors, a wirelessly recharging battery and a mission to deliver merchandise right to your doorstep. The new drone is the result of collaborative efforts by the Univ. of Cincinnati and AMP Electric Vehicles makers of the WorkHorse all-electric delivery truck. The newly designed, autonomous unmanned aerial vehicle was developed to work in tandem with AMP's delivery trucks to deliver packages in an efficient way.
The potential of terahertz waves has yet to be reached because they are difficult to generate and manipulate. Current sources are large devices that require complex vacuum, lasers and cooling systems. A Northwestern Univ. team is the first to produce terahertz radiation in a simplified system. Their room-temperature, compact, continuous terahertz radiation source is six times more efficient than previous systems.
A cooing, gesturing humanoid on wheels that can decipher emotions has been unveiled in Japan by billionaire Masayoshi Son, who says robots should be tender and make people smile. The machine, called “Pepper”, has no legs, but has gently gesticulating hands. It recently appeared on a stage in a Tokyo suburb along with announcement that it will go on sale in Japan next year for the equivalent of US$1,900.
In the last 10 years, the presence of wireless technology has blossomed in the industrial and manufacturing space, where a multitude of technologies, from Bluetooth to Zigbee to RFID, have been successfully employed to monitor conditions of machinery, products under assembly and the work force.
The ability to adapt to changing situations is critical for today’s labs. Today, many lab equipment systems are designed with the flexibility to accommodate these needs. Time is also of utmost importance, and the ability for a researcher to walk away from their work, or monitor it on the go, is a new standard.
After another year of flat spending in 2013, global investment in R&D is forecast to grow by 3.8% to $1.6 trillion in 2014, according the annual R&D Magazine Global Funding Forecast. In the U.S., federal spending is forecast to increase modestly (1.5%), another promising sign, but it’s fair to say the pressure is still on to do more with less, particularly in Big Pharma where recent R&D cuts have been the most dramatic.
Pharmaceutical companies are constantly seeking ways to improve efficiency in order to increase productivity, all while speeding up innovation and protecting intellectual property (IP). The use of mobile applications (apps) in the laboratory has been investigated as a means to achieve these goals. By allowing scientists to move freely around the laboratory, mobile apps add value to suboptimal processes requiring non-value-added steps.
Scientists at NIST and the Joint Quantum Institute have shown how attempts to "push" part of a light beam past the speed of light results in the loss of the quantum data the light carries. The results could clarify how noise might limit the transfer of information in quantum computers.
A new twist on 3-D imaging technology could one day enable your self-driving car to spot a child in the street half a block away or play “virtual tennis” on your driveway. The new system, developed by researchers at the Univ. of California, Berkeley, can remotely sense objects across distances as long as 30 feet, 10 times farther than what could be done with comparable current low-power laser systems.
A demonstration by NASA and MIT engineers last fall showed, for first time, that a data communication technology exists that can provide space dwellers with the connectivity we all enjoy here on Earth. Next month, the team will present the first comprehensive overview of the performance of their laser-based communication uplink between the moon and Earth, which beat the previous record transmission speed last fall by a factor of 4,800.
Scientists from the Biorobotics Laboratory (BIOROB) at EPFL in Switzerland have developed small robotic modules that can change their shape to create reconfigurable furniture. Like Lego bricks, these robotic pieces, or Roombots, can be stacked upon each other to create various structures. Each piece has three motors that allow the module to pivot with three degrees of freedom, and each also has a battery and wireless connection.
A new way of measuring sea level using satellite navigation system signals, such as GPS, has been implemented by scientists in Sweden. Sea level and its variation can easily be monitored using existing coastal GPS stations, the scientists have shown, and requires just two antennas that measure signals both directly from the satellites and signals reflected off the sea surface.
Now researchers have developed a new way to measure the thickness of paint layers and the size of particles embedded inside. A technique called terahertz reflectometry is used to characterize coats of paint without damaging them. No other current methods can do this successfully, and the technique could be useful for a variety of applications from cars to cancer detection.
