when the electromagnetic fluctuations of radio antennas are in sync with those of their surroundings, a phenomenon known as resonance can amplify radio signals.
One example of resonance is the way a playground swing will climb higher from repeated pushes.
and radio signals could propagate through, they explained. For the resonance to work, the thickness of this matched layer and the plasma sheath must be smaller than the wavelengths of the radio signals used for communication, the scientists noted.
The properties of the plasma sheath can vary during flight, complicating any efforts to generate resonance,

#Fove eye-tracking headset aims to shake up VR, launches on Kickstarter Update: Fove has reached its Kickstarter goal as of 6: 47 pm JST on Friday, May 22, just three days into its 45-day campaign.
Oculus managed to raise US$400, 000 during its first 24 hours on Kickstarter, but it still exciting to see an Asian competitor hit its target so quickly.

when social media behemoth Facebook finalized its acquisition of the company for a staggering US$2 billion.
Even before Facebook surprise acquisition, Oculus had piqued (or, perhaps, re-piqued) consumer interest in virtual reality.
Sony entered the budding space with the announcement of its Project Morpheus headset in March last year.
Facebook chairman Mark Zuckerberg allegedly tested out Sony VR hardware, designed for its Playstation 4 console,
a week before announcing his company intent to buy Oculus. Just a month after Morpheusunveiling and Facebook shock announcement,
a silent competitor to both was setting up its office at Tokyo University Intellectual Backyard startup incubator.
and, of course, playing video games wants to revolutionize the resurgent VR platform by integrating advanced eye-tracking technology into its own headset.
While headsets like Oculus and Morpheus display everything in the virtual environment in sharp focus imagine a wrap-around HDTV Fove eye-tracking technology recreates the depth of field that human eyes see naturally.
This effect is achieved on Fove 2560×1440 display thanks to a graphics engine that adjusts its focus based on where a user is gazing in real time.

#Researchers Power Small Electronics Using Wi-fi: Clarkson Waves Your Wi-fi router already brings you Netflix and cat pictures,
but someday it might become even more important to your life. A group of researchers from the University of Washington were able to send energy from a Wi-fi router to low power electronics from up to 28 feet away,
without interfering with the router and neighboring routersability to transmit data. They call their technology Power over Wi-fi (Powifi.
Using Atheros chipsets, the researchers made several Powifi routers that worked as normal but also sent meaningless packets of data over multiple 2. 4ghz channels.
They programmed these routers to send these nintrusive power trafficonly when the router isn sending data to connected devices.
They then built four low power devices: a temperature sensor, a camera, a coin battery charger and the AA battery charger shown above.
Each of those devices was equipped with a harvester that converted the radio waves from the router
whether it contained actual data or the aforementioned power traffic into direct current voltage, which was boosted then to a usable voltage with a DC-DC converter.
In their tests, they were able to operate the camera up to 17 feet away, the temperature sensor up to 20ft away and the battery chargers up to 28 feet away from their router.
Using a 2. 4ghz antenna and their harvester the researchers also built a wireless USB charger (top image.
It was able to charge a Jawbone UP 24 from 0%to 41%in 2. 5 hours while placed a couple of inches away from their router.
Finally, the researchers tested how their routers fared in real world settings. They asked six different households to use a Powifi router for their usual Internet activities for a few days.
They also installed harvester-equipped temperature sensors 10 feet away from each router. Their results showed that the routers performed well,
adjusting for client traffic both within the households and from neighboring routers while still sending enough power to the temperature sensors.
The researchers hope that their technology will lead to battery-free sensors and mobile devices that are powered continuously by Wi-fi routers.

#IBM-Led Team Pulls Off Major Chip Feat IBM Research on Thursday announced that an alliance it leads has produced the first 7nm node test chips with functioning transistors.
The 7nm chips are the result of the first program out of IBM's 2014 US$3 billion investment in research--a five-year investment that aims to push the limits of chip technology to meet the needs of cloud computing
said Mukesh Khare, vice president of IBM Semiconductor Technology Research.""We intend to incorporate 7nm into the road maps for IBM systems in the future,
"he told Technewsworld.""This milestone is the first step towards a silicon-based proof point with all elements demonstrated in our 300nm research facility at Albany."
"The History of Sige Technology IBM introduced Sige technology into mainstream manufacturing in 1989. It currently is collaborating with AMD on program to develop Sige stressed-silicon 65nm technology.
the need for faster CPUS and more processing power grows. However, it's becoming increasingly difficult to attain higher clock speeds,
That has led semiconductor firms to look at packing more cores onto their processors. The number of transistors in an integrated circuit doubles roughly every two years, according to Moore's Law,
Intel apparently expects to be able to build 5nm transistors at some point.""The higher the density of transistors, the more cores you can put in a given space,"noted Rob Enderle, principal analyst at the Enderle Group."
"A very high-density part would be ideal for the cloud, which is why ARM
and Intel are also chasing it, "he told Technewsworld. Challenges IBM Will Face The IBM alliance has to ensure that it develops technology that will let it manufacture Sige transistor channels in high volumes,
Enderle cautioned.""This is where most of the really promising technology fails, "he pointed out.""They can get it to work in the lab,
The control software evolved directly from the Dextre and Canadarm programs at MDA, and the vision was adapted from their satellite navigation work for the CSA.

#Smart keyboard cleans and powers itself and can tell who you are In a novel twist in cybersecurity,
self-powered smart keyboard that can identify computer users by the way they type. The device, reported in the journal ACS Nano, could help prevent unauthorized users from gaining direct access to computers.
Zhong Lin Wang and colleagues note that password protection is one of the most common ways we control who can log onto our computers
and see the private information we entrust to them. But as many recent high-profile stories about hacking

and speed that can accurately distinguish one individual user from another. So even if someone knows your password,
he or she cannot access your computer because that person types in a different way than you would.
It also can harness the energy generated from typing to either power itself or another small device.
The scientists conclude that the keyboard could provide an additional layer of protection to boost the security of our computer systems r
