Fewer cords, smaller antennas and quicker video transmission. This may be the result of a new type of microwave circuit that was designed at Chalmers Univ. of Technology. The research team behind the circuits currently holds an attention-grabbing record: 40 Gbps, about twice as fast as the previous record at 140 GHz. The results will be presented at a conference this week in San Diego.
Sensors developed by SmartCardia, a spin-off from EPFL in Switzerland, use various biological vital signs to transmit data to a host of everyday objects. This data, which includes heart rate, respiration activity, skin conductivity and physical exertion, can be used dim a light, control immersive playing on a computer, and track yoga exercises in real time.
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.
The fastest land animal on Earth, the cheetah, is able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop. Now, researchers have developed an algorithm for bounding that they’ve successfully implemented in a fully functional robotic cheetah.
A habitual party crasher, Apple has a history of arriving late and making a big splash in various gadget categories. But can it continue with the Apple Watch? Smartwatches have been around for a few years, but makers such as Samsung and Sony have failed to make them a runaway hit. Apple's Watch won't go on sale until early 2015 and raises questions: Can the company work its magic as it has in the past?
Rice Univ. wireless researchers have found a way to make the most of the unused UHF TV spectrum by serving up fat streams of data over wireless hotspots that could stretch for miles. In a presentation today at the Association for Computing Machinery's MobiCom 2014 conference, researchers will unveil a multiuser, multiantenna transmission scheme for UHF, a portion of the radio spectrum that is usually reserved for television broadcasts.
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.
