German Wi-Fi Network Breaks Speed Record 40Gbit per second
Experts of the Fraunhofer Institute for Applied Solid State Physics along with the Karlsruhe Institute for Technology have accomplished the wireless transmission of 40 Gbit/s at 240 GHz over a certain distance of one kilometer. Their newest presentation puts a new world record and even links in seamlessly with the potential of optical fiber transmission. In the near future, like radio links has the ability to close gaps in delivering internet by supplementing the network in remote areas and also spots that are not easy to access.
Electronic, mobile phone as well as networked – transforming media consumption habits of modern society demand the much faster transmission of increasing volumes of data. In comparison with the European standard, Germany lags behind in the increase in the fiber-optic network , based on research from the FTTH Council Europe. Deploying modern fiber-optic cables is expensive and even complicated whenever there are natural or urban barriers for instance rivers or perhaps traffic junctions. Broadband radio links help get over this kind of crucial places, in this manner empowering the development of the network infrastructures. In rural areas they are generally an inexpensive as well as a very useful substitute for “Fiber to the Home”.
Experts have finally established a new world record in wireless data transmission: For the very first time, completely integrated electronic transmitters with receivers have been made for a frequency of 240 GHz, that enables the transmission of data rates of up to 40 Gbit/s. This is equivalent to the transmission of an entire Dvd movie in under a second or simply 2400 DSL16000 internet connections. Ranges of over one kilometer are actually covered by utilizing a long range demonstrator, which the Karlsruhe Institute of Technology establish between two skyscrapers as part of the project “Millilink”. “We have managed to develop a radio link based on active electronic circuits, which enables similarly high data rates as in fiber- optic systems, therefore allowing seamless integration of the radio link”, states Prof. Ingmar Kallfass, who coordinated the project at Fraunhofer IAF within the field of a Shared Professorship between IAF and KIT. As 2013, Kallfass with the University of Stuttgart, whereby he continues to take the project.
High Frequencies allow Fast Data Transmission
Utilizing the high frequency range between 200 and 280 GHz not only allows the quick transmission of large volumes of data, but will also bring about compact technical assembly. As the size of electronic circuits and also the antennae scales with frequency/ wavelength, the transmitter and receiver chip only measures 4 x 1.5 mm². The semi-conductor technology designed at Fraunhofer IAF, based upon transistors with high carrier mobility ( HEMT ), makes it possible to employ the frequency between 200 and 280 GHz with active transmitters and receivers in the form of compact, integrated circuits. The atmosphere displays low attenuation with this frequency range, which allows broadband directional radio links. “This makes our radio link easier to install compared to free-space optical systems for data transmission. It also shows better robustness in poor weather conditions such as fog or rain”, states Jochen Antes of KIT.
Up to this time, radio links were unable to directly transfer the data rates of glass fiber. It might change in the future, since the test setup of the project exhibits. Like an excellent performance system would even have the advantage of the so-called bit transparency, i.e. ( the signal of a glass fiber could be fed directly and also without energy-consuming transcoding into a radio link). This could then be transmitted and redirected into a glass fiber. The record data from the test setup is usually the initial stages. “Improving the spectral efficiency by using more complex modulation formats or a combination of several channels, i.e. ( multiplexing, will help to achieve even higher data rates”, states Antes. This might provide groundbreaking momentum to the development of the broadband network.

How Strong and Secure is Your Password?
A password is generally a secret word along with series special characters and numbers that’s used in authentication, to help you to prove identification along with gain access to some sort of account. An appropriate password needs to be managed secret from those prohibited to gain accessibility. There’s not necessarily for an account password to be precise words or numbers, an account password which is definitely not precise words or numbers, moreover combining with special characters can be more difficult for someone to guess a desirable protected account. But during this day there are advance software’s have been developed by some bad guys to generate a particular correct combination of a password within just a minute.
That’s why it’s better to update and to know how secure and strong your account password is. Then I recommend some kind of “Password Checker”. Lately, when I search the phrase “Password Checker” on the Google Search Engine I came up with some results. Based on the results, I found three websites which offer a free service in checking a password security but before that I investigate first if these websites are trusted and safe. Then I go to www.scamadviser.com, I check the trust rating of these websites, luckily they got a high trust rating. Therefore these websites are advisable to be a “Password Checker”. (See the list of websites below which offers a free service in checking a password security.)
A Microsoft Password Checker, checks your password strength and rate it in four categories: weak, medium, strong and best. It offers also some tips about how to create passwords that are easy for you to remember but difficult for others to guess.

Right Body Posture in Front of Computer
At this point, a lot of us spend our day facing a PC, typing away, sitting uncomfortably, and chatting on the handset without using our hands to be able to finalize our job. The majority of us also suffer pain from neck, back as well as eye anxiety. Did you realize that is a right method to sit down at the computer desk which can help you ease the pain as well as discomfort.
So what is correct computer posture? Several body placements that work together to ensure you suffer the least amount of strain, including the best position to of your eyes, back, neck, foot and knee placements. Even lighting can have a strong impact on our bodies.
Bad computer posture symptoms can be sore wrists, shoulder and neck strain as well as low back pain, tired eyes and even headaches. Long term bad posture can cause long term chronic pain, but can easily resolved by taking the time to ensure we are sitting correctly.
Many offices now work to improve their employee’s computer posture to ensure their long term health and happiness. Taking these relatively few measures of safety is more than just a luxury and could raise your productivity at work thus the potential benefits of these measures by far outweigh the costs if any.
Have a look at the above diagram, and check in with your body. After a long day of sitting at your desk, where does your body feel strain, there is probably a change that needs to be made. Talk to your employer about getting an ergonomics specialist to come in and check out the workstations of all their employees. If you are suffering from strain, make an appointment to assist you in finding some relief.

Google Glass: Google's latest and hottest gadget
Google's latest and hottest gadget is the Google Glass it needs a little introduction. Since its public unveiling in April 2012, the tiny head-mounted Android computer has been collecting controversy and sociological analysis. It is currently available in limited beta to eminent members of the tech community and to a selection of Glass Explorers.
Google Glass is a wearable computer with an optical head-mounted display (OHMD) that is being developed by Google in the Project Glass research and development project, with a mission of producing a mass-market ubiquitous computer. Google Glass displays information in a Smartphone-like hands-free format, that can communicate with the Internet via natural language voice commands.
While the frames do not currently have lenses fitted to them, Google is considering partnerships with sun-glass retailers such as Ray-Ban or Warby Parker, and may also open retail stores to allow customers to try on the device. The Explorer Edition cannot be used by people who wear prescription glasses, but Google has confirmed that Glass will eventually work with frames and lenses that match the wearer's prescription; the glasses will be modular and therefore possibly attachable to normal prescription glasses.

The awesome Galaxy Gear Smart Watch revealed
Lately, Samsung revealed their Galaxy Gear smart watch, a couple before the official opening of the IFA Berlin trade show. After an early reveal of the Gear on the wrists of Icona Pop singers in New York, Samsung Chief executive officer J.K. Shin announced the main thing in the Tempodrom event venue, in front of exactly what we're informed is a crowd of 2, 500 people.
The device's specs are quite less exciting compared to what was rumored : a 1.63-inch, 320 x 320 pixel Super AMOLED screen, a 1.9-megapixel camera (put on the wristband), an 800MHz processor, 512MB of RAM and 4GB of storage space.
If perhaps you're questioning what exactly that camera could be used for, here’s: Memographer. It's a feature that allows users pictures and videos on the move and shares them on social networks. Definitely, that doesn't appear as well revolutionary, however the reality that you are able to do it from your own wrist without taking the phone from your pocket it makes a bit more useful.
Gear provides support for voice operation, allowing the user hands-free calls right away from the watch. Additionally you can music played on a Samsung Galaxy device, and it has a built-in pedometer that can be used to monitor physical activity.
Samsung describes Galaxy Gear the "perfect partner for the Galaxy Note 3." The Gear will ship with the Note 3 and is fully compatible with it. Samsung doesn't go into details on compatibility with other devices, but claims the Gear will be compatible with the Galaxy range.

Samsung Flexible Phone Displays
In last January 2013 Samsung officially released their flexible OLED displays, naming it YOUM displays. YOUM panels are bendable - however it's likely that the very first product to manage those displays will in fact be rigid. The display is generally "curved" thought.
Many predicted that the very first products with flexible OLEDs are going to be mobile phones. Those phones will be lightweight and thinner compared to existing mobile phones , as well as the display will be much stronger (a plastic material based AMOLED will likewise also be shatterproof). It's also possible that Samsung will indeed utilize a curved display.
When are we going to see the very first YOUM product?
Samsung did not give a particular commitment, however it might seem that the company is looking to begin manufacturing YOUM panels in 2013. We think that the production volume will be minimal, and the panels will be somewhat more expensive when compared with glass based panels. The OLED Association states that the Note 3 Smartphone or tablet is going to be the very first product with a plastic OLED, 5 .9" or more in size. It will certainly ship in the quarter of 2013, however in limited quantities.

Low Cost 3D Printer: Formlabs Form 1
Desktop computer 3D printing has got mainly become the sector of extrusion-based machines. Although this process’s print size, speed as well as quality have developed over the years, it often lags behind the capabilities of pricier, professional stereolithography devices, in which Ultra-violet light treats remarkably thin layers of resin to produce objects equivalent to manufactured goods.
Creating the the Form 1 printer at a consumer price range has up to now become an challenging objective , however a today trio of MIT grads with remarkable backers revealed a new machine , known as the Form 1 , which could possibly deliver professional-grade 3D prints to the home garage .
Plastic material isn't placed on a build platform; rather than, components are taken out from a gooey pool of resin. Along with its increased precision, this method also creates translucent components as well as complicated geometries possible. It really can print objects 4 .9 by 4 .9 by 6 .5 inches with layers that are only 25 microns (0 .001 inches) thick.
The technology is unique, yet the product’s design is spectacular. Cranor and his co-founders invested early in brilliant engineering as well as high quality industrial design. The Form 1 has only several moving parts making for silent operating process, although the anodized aluminum casing provides it a respectable, serious appearance. The Formlabs staff views the product in unique classification compared to the present class of plywood-clad, inexpensive printers and wanted the product design to reflect that.
The translucent orange box at the top of the machine covers the resin inside from ultra-violet rays, but likewise helps designers look at their products getting built in real time. “The 360-degree view was a conscious decision, so the part is the focus” states Lobovsky “The printer is cool, but your project is cooler.”

The Days of the Transparent Smartphone
The Taiwan’s Polytron Technologies is a subsidiary of US firm Polytronix. Polytron wants to transform the method we see and deal with glass which is among mankind’s most well-known inventions. Polytron creates huge projection touch screens, selectively opaque glass, holographic glass, LED-impregnated glass, color-changing glass, rainbow glass, as well as glowing glass. Today, they’ve put their views on transparent glass Smartphone's.

Polytron targets to finalize their Smartphone by the end of 2013 , moreover at least one breathless blogger believes it’ll become a competitor of Apple’s iPhone , comparing by the prototype Polytron provides more work ahead of them . However the phone’s transparency, its main appeal, is an issue they’ve already solved. The firm’s flagship product, Polyvision Privacy Glass, is an electrically switchable, selectively opaque or simply transparent pane of glass.
Each Polyvision Privacy pane is a sandwich of glass, conductive material, and liquid crystal film. In its own natural state, the central crystalline structure is randomly oriented, scattering incoming light to make the surface opaque. But when an electric current is introduced, the liquid crystals line up and become transparent, transmitting light from one side to the other.
Polytron additionally creates a huge transparent touchscreen monitor known as the Polytouch Frame. Probably both of these technologies combine in their transparent Smartphone.
Generally speaking, it’s awesome to see transparent Smartphone’s get shape. Yet the technology behind them isn't new. Samsung, for instance, continues to be tested with transparent screens for several years.

Smart Mirror By Seraku: LCD Monitor Rendered Transparent
Recently, Japan’s Smartphone & Mobile Expo has demonstrated a few unique technologies in the past bringing exhibitors together with consumers in person. What exactly it was clear that interesting this year is usage of a mirror to see weather conditions, temperature, or the most recent news. The concept has become introduced and exhibited by a Japanese company, Seraku. The mirror is definitely an LCD monitor which is rendered transparent with the aid of a semi-transparent reflective glass.
A multitude of features display on the mirror, which are actually Android apps mirrored from a tablet. You don’t actually need to tap on the mirror thanks to RF proximity sensors that help you in providing input through gestures. This magic mirror actually reminds us of Samsung’s smart window, which is capable of turning any transparent surface to a touch-sensitive interface.

Analyze Any Urine Sample via Smartphone
The Inventor Myshkin Ingawale who's best known for developing a needle-free test for hemoglobin got some laughs when he unveiled his latest project. It's revolutionary, he said, and will one day put your future "in the toilet."
Background: Ingawale and a small team have developed uChek, a smartphone app that analyzes your urine. If it gets through the app store's screening process, it'll be the first app that can visually analyze any urine sample with any type of urine test.
A lot of people living with chronic diseases, like diabetes, rely on urine analysis to easily check for chemical changes. The dipstick is the standardized way to test urine: you pee into a cup, then dip the stick into the cup. Boxes on the stick change color based on what's in the urine. A certain box changes shade for an excess of proteins, another changes for the number of leukocytes. Problem is, there's no standard dipstick: different dipsticks change different colors. And they're not always easy to read with the naked eye.
uChek creates a cheap, universal way to read urine tests by standardizing those color indicators. How? Creators upload color "keys" saying blue means this, orange means that, and so on.
With the colors standardized, you can test your urine using any generic urine test. First you place your dipstick in a color-correction sleeve--sort of a little rainbow palette that makes sure your phone's camera is properly adjusted to the room's light--then you snap a photo of the stick. The app analyzes the colors, then spits out statistics on your urine. More importantly, it spits out understandable statistics: you can click on a specific stat to determine what it means. Do you have leukocytes? Tap to learn that's potentially caused by a urinary tract infection.
At the talk, Ingawale explained how the technology could eventually be added to bathrooms, giving you a free urine test whenever you, uh, go.

The Best Free Antivirus of 2013
The antivirus is a software that used to stop, detect as well as eliminate viruses on a computer. However free security applications don’t usually provide as much functions as commercial suites, their quiet simplicity tend to be beneficial of course the cost can’t be defeated.
We’ve rounded up the best free antivirus products (see below) to enable you to choose the best product to meet your needs.
Avast Free Antivirus
This friendly and attractive antivirus tool is our recommended free option. That’s partly thanks to great malware protection, but it also offers a generous set of secondary features (by the standards of free software), including a configurable sandbox and an easy-to-use remote assistance tool. A commendably low impact on system resources seals the deal.
