Brazilians were outraged when they learned their country was a top target of the U.S. National Security Agency's overseas spying operation, with data from billions of calls and emails swept up in Washington's top secret surveillance program. Yet when it comes to the cloak and dagger effort of catching philandering lovers, all high-tech weapons appear to be fair game.
A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennas that absorb more sunlight than fully natural ones. In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles into a structure that soaks up sunlight.
NASA’s Robonaut currently exists on the ISS as a torso, bolted to a pedestal, and is connected to the station with wires for power and control. The robot will be upgraded soon with legs and batteries that will allow it to move freely through the station.But that free movement will only be possible if all of the wires are gone – including the ones used for control and monitoring.
Flight safety experts studying recent high-profile plane crashes found sudden autopilot disconnection to be a design flaw that creates unnecessary emergencies by surprising pilots during critical, high-workload episodes. Eric E. Geiselman, along with coauthors Christopher M. Johnson, David R. Buck, and Timothy Patrick, have combined expertise as pilots, crew resource management instructors, and human factors researchers.
The TDRS fleet provides communications support to an array of science missions, as well as several launch vehicles. The network has provided critical real-time communication with NASA’s human spaceflights since early in the Space Shuttle Program. TDRS network operations continue to provide support for International Space Station activities.
This week on WDD’s HotSpot, brought to you by Memory Protection Devices, xPico Wi-Fi helps consumers leverage mobile solutions; spoofing an 80 million-dollar yacht; bulk metal foil COTS resistors; and a synthesized RF signal generator from Saelig.
The quadcopter, which was developed at TU Vienna, can negotiate its way through a room completely on its own. It does not need any human interference, and in contrast to other models, it is not assisted by any external computer. All the necessary computing power in on board; the image processing is done by a standard smartphone.
Nano-sized gas sensors in mobile telephones that measure the atmospheric humidity are nothing new as such. However, so far it was necessary to rely on complex lithographic methods to produce the required nano-structure of the sensors, and they have the added disadvantage that they do not work well on uneven surfaces.
Smartphones are getting bigger as people use them more to watch movies and play games. A new one from Samsung is beyond big. With a screen measuring 6.3 inches diagonally, the Galaxy Mega is almost as big as a 7-inch tablet computer. The difference: It makes phone calls.
In a partnership between NTU, JTC, and Induct Technologies, and supported by the Singapore Economic Development Board (EDB), an autonomous electric shuttle manufactured by Induct is expected to ply the two kilometer route providing a safe, reliable, and environmentally-friendly alternative mode of transportation.
In a story that has everyone talking, Elon Musk of Paypal, Tesla Motors, and Space X fame has announced his newest plan for revamping the world of public transportation. The system is called Hyperloop and it would allow passengers to travel the 350 miles from LA to San Francisco in 30 minutes.
When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals – a technique known as electronic attack (EA) or jamming. Conversely, electronic protection (EP) technology prevents hostile forces from using EA methods to disable U.S. radar equipment assets.
Monnit has made some recent enhancements to the wireless range extender, improving the RF communication and performance of networks using the device. Monnit wireless range extenders allow you to extend the coverage area of your wireless sensor network.
As LTE networks start to mature across the world, more and more carriers are looking introduce voice services on LTE networks using a technology called Voice over LTE (VoLTE). What is not always understood is that voice services on LTE are very different from those on 2G and 3G networks. An appreciation of the differences leads us to the conclusion that we must think and act differently for 4G.
RFMW has announced design and sales support for a 6 GHz single-pole, triple throw (SP3T) switch from TriQuint Semiconductor. The TQP4M0011 is controlled using positive DC voltages from 1.8 to 5 V.
The introduction of high-density microelectronics enabled the incorporation of signal conditioning and processing functions inside the LVDT housing rather than requiring an external box. The DC-operated LVDT maintains all the desirable characteristics of the AC-operated LVDT, but has the simplicity of DC operation. It is comprised of an AC-operated LVDT and a carrier generator/signal conditioning module.
This week on Engineering Newswire, brought to you by Interpower Corporation, the premier supplier for power system components with a one week manufacturing lead-time and over 4 million parts in stock, we’re hacking yachts, stopping trash can spies, creating feelings with Disney research, and putting the first Navy Infrared Camera in the crow’s nest.
Teseq now offers a 100 A, 3-phase burst pulse coupling/decoupling network (CDN) designed for electrical fast transient (EFT) or burst testing. The new manual CDN 3083-B100 is ideal for use in the power and telecom industries.
Consumers waiting for Microsoft's revamped version of its latest Windows operating system will be able to get the software beginning Oct. 17. The release date for Windows 8.1 is nearly a year after the debut of Windows 8, a dramatic overhaul of the operating system that has been powering most personal computers for decades.
A team at the University of California, Riverside Bourns College of Engineering has developed a novel way to build what many see as the next generation memory storage devices for portable electronic devices including smart phones, tablets, laptops, and digital cameras.
Antivirus software running on your computer has one big weak point - if a new virus is released before the antivirus provider knows about it or before the next scheduled antivirus software update, your system can be infected. Such zero-day infections are common.
ETH-researchers cannot "beam" objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A to B – for the first time in an electronic circuit, similar to a computer chip.
Apple's shares srged passed the $500 threshold — their highest level since January. Wednesday's gains came a day after activist investor Carl Icahn said he thinks the iPhone maker should do more to revive its stock price. The outspoken billionaire said in Twitter posts Tuesday that he had acquired an unspecified stake in Apple and had spoken to its CEO about boosting share repurchase plans.
Microsoft said it has fixed a problem that prevented some people from getting their email on Outlook.com, but mobile users might still be having problems.Service had been restored on the Web shortly after 2 p.m. PDT Wednesday, according to an update on Microsoft's website.
A group of smartphone app developers and weather experts discovered a way to use the temperature sensors built into smartphone batteries to crowdsource weather information. These tiny thermometers usually prevent smartphones from dangerously overheating, but the researchers discovered the battery temperatures tell a story about the environment around them.
