#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.

#DM Blade Supercar has 3d printed Chassis: The Arduino of Cars Last year we saw Local Motorsstrati, a compact car with a 3d printed body, seats, windshield and support structures.
Divergent Microfactories (DM) Blade prototype supercar looks much better and is apparently much more powerful than the Strati,
but DM pride and joy is what inside the car. The DM Blade has a 700hp four-cylinder engine
But just like the Arduino, Raspberry Pi and other single-board computers, DM will measure its success by how many vehicles will be built
#Fove VR Headset Locks Onto Your Gaze Fove is the first virtual reality headset to feature eye-tracking--meaning, among other things,
that characters you view on screen can look right back at you. So far, close to 500 people have pledged nearly US$200,

and the ability to aim with the eyes that are separating the Fove from a growing pack of VR headsets preparing to come to market, according to Yuka Kojima, Fove cofounder and CEO."
"Fove enables users to truly immerse themselves into virtual reality worlds by allowing instant and precise user interface control using sight,
The company's proprietary algorithm, aka"Foveated Rendering,"measures depth of field focus by calculating the parallax between the wearer's eyes."
"Fove tracks a user's gaze and calculates where in 3d space a user is said looking,
"Kojima.""This enables the graphics engine to adjust focus and allocate rendering resources accordingly, giving the user the most natural VR experience."
"Along with giving wearers more control, the Fove's eye-tracking"drastically reduces"the motion sickness that has plagued many consumers who use headsets that rely only on head-tracking,
Kojima pointed out.""Fove also allows for greater emotional exchange with in-game characters, often leading consumers to perceive the characters as real,

such as healthcare, social networking and education. Virtual reality is said the future Roger Entner, principal analyst at Recon Analytics.
"There's some early eyeball tracking in the Samsung galaxy 6--and that works, more or less. It's a bit more than less,
the VR headset could be poised for success, he suggested. Gaming is the sector with the lowest-hanging fruit, Entner observed,
#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 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

With display devices such as HMDS it is possible to browse information without taking out a separate smart device.
Users can therefore receive information without occupying their hands. The problem however is that it is difficult to manipulate the information received.
Despite being ring-sized the device includes motion sensors for text input an NFC tag reader and wireless communication functionality.
This technology allows operators to manipulate data without stopping what they are doing and with a minimum of movement even while holding other tools.
and collects data on each as they interact with each other the researchers have learned already more about how T cells major players in the immune response become activated during infection.
The device is based on microfluidic technology developed by Joel Voldman an MIT professor of electrical engineering and computer science (EECS) in 2009.
This technique allows the researchers to follow hundreds of cell pairs over time and monitor

However, current ATRP methods by design use metal catalysts a major roadblock to applications for which metal contamination is an issue,
This new method of radical polymerization doesn involve heavy metal catalysts like copper. Their innovative, metal-free ATRP process uses an organic-based photocatalyst
Now this method opens doors for a new class of organic-based photoredox catalysts. Controlling radical polymerization processes is critical for the synthesis of functional block polymers.
Software developed by Fraunhofer researchers will ensure an optimum use of the available wind energy at any time.
Considering meteorological data the software for the new ship type uses a navigation algorithm to calculate a route with the optimum angle to the wind for maximum effect of the design. ith our weather routing module the best route can be calculated
such as aero-and hydrodynamic data as well as weather forecasts from the meteorological services, such as wind speed and wave height.
By the end of January 2015, the software will be handed over to the company Lade AS.
#Solar chip monitors windows It happens all too often in the cold times of the year:
By keeping both processor and chip extremely small, the latter is extremely frugal. In addition, the researchers constructed switches that consume little energy,
Depending on the user preferences, the sensor can be set so that it wakes up every few minutes,

smart dog collars. In the Media Laboratory class MAS 834 (Tangible Interfaces), Liang, Gips, and Noah Paessel SM 5 created dog collars equipped with RFID technology and accelerometers.
These tracked a dog movement, communicated with smart collars worn by other dogs, and pushed that data online.

#Nanoscale mirrored cavities amplify connect quantum memories The idea of computing systems based on controlling atomic spins just got a boost from new research performed at the Massachusetts institute of technology (MIT) and the U s. Department of energy (DOE) Brookhaven National Laboratory.
Such spin-photon interfaces are thought to be essential for connecting distant quantum memories, which could open the door to quantum computers and long-distance cryptographic systems.

#Computing at the speed of light University of Utah engineers have taken a step forward in creating the next generation of computers
and mobile devices capable of speeds millions of times faster than current machines. The Utah engineers have developed an ultracompact beamsplitter the smallest on record for dividing light waves into two separate channels of information.
and shuttle data with light instead of electrons. Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics.
The overhead view of a new beamsplitter for silicon photonics chips that is the size of one-fiftieth the width of a human hair.
University of Utah Electrical and Computer engineering Associate professor Rajesh Menon is leading a team that has created the world smallest beamsplitter for silicon photonic chips.
The discovery will lead to computers and mobile devices that could be millions of times faster than machines today
because the information or data that is computed or shuttled is done through light instead of electrons. Image credit:
Dan Hixson/University of Utah College of Engineeringsilicon photonics could significantly increase the power and speed of machines such as supercomputers, data center servers and the specialized computers that direct autonomous cars and drones with collision detection.
Eventually, the technology could reach home computers and mobile devices and improve applications from gaming to video streaming. ight is the fastest thing you can use to transmit information,
says Menon. ut that information has to be converted to electrons when it comes into your laptop.
In that conversion, youe slowing things down. The vision is to do everything in light. Photons of light carry information over the Internet through fiber-optic networks.
But once a data stream reaches a home or office destination the photons of light must be converted to electrons before a router
or computer can handle the information. That bottleneck could be eliminated if the data stream remained as light within computer processors. ith all light,
computing can eventually be millions of times faster, says Menon. To help do that, the U engineers created a much smaller form of a polarization beamsplitter
(which looks somewhat like a barcode) on top of a silicon chip that can split guided incoming light into its two components.
Before, such a beamsplitter was over 100 by 100 microns. Thanks to a new algorithm for designing the splitter
Menon team has shrunk it to 2. 4 by 2. 4 microns, or one-fiftieth the width of a human hair and close to the limit of what is physically possible.
The beamsplitter would be just one of a multitude of passive devices placed on a silicon chip to direct light waves in different ways.
By shrinking them down in size, researchers will be able to cram millions of these devices on a single chip.
mobile devices such as smartphones or tablets built with this technology would consume less power, have longer battery life
and generate less heat than existing mobile devices. The first supercomputers using silicon photonics already under development at companies such as Intel
and IBM will use hybrid processors that remain partly electronic. Menon believes his beamsplitter could be used in those computers in about three years.
Data centers that require faster connections between computers also could implement the technology soon, he says.
