Fedora Will Get Full Mp3 Support, As IIS Fraunhofer Terminates Mp3 Licensing Program (fedoramagazine.org)
An anonymous reader quotes Fedora Magazine: Both MP3 encoding and decoding will soon be officially supported in Fedora. Last November the patents covering MP3 decoding expired and Fedora Workstation enabled MP3 decoding via the mpg123 library and GStreamer... The MP3 codec and Open Source have had a troubled relationship over the past decade, especially within the United States. Historically, due to licensing issues Fedora has been unable to include MP3 decoding or encoding within the base distribution... A couple of weeks ago IIS Fraunhofer and Technicolor terminated their licensing program and just a few days ago Red Hat Legal provided the permission to ship MP3 encoding in Fedora. -
Underwater Pumped-Storage Hydroelectric Project Completes Its First Practical Test (forschung-energiespeicher.info)
What if you built massive concrete spheres -- 98 feet in diameter, with 10-foot walls -- under the ocean to help generate electricity during peak periods? Slashdot reader nachtkap reports that German researchers just finished testing their 1:10-scale prototype StEnSEA: It was retrieved from Lake Constance, where it was submerged at a depth of 100 meters [328-feet] since November. The system was developed by the Fraunhofer-Institut IWES in Kassel, Germany in collaboration with its inventors... The German Trade Department and Department of Education and Research as well as the German construction company Hochtief are also involved with the project.
The system's hollow concrete spheres are intended to be used in conjunction with off-shore wind-farms to serve as energy storage for peak hours. The spheres are ultimately supposed to be submerged near off-shore wind-farms and pumped free of water with excess energy. When additional energy is needed during peak hours the system goes into reverse and water rushes in, driving a turbine... At 700 meters the system has a capacity of 20MWh, with a linear capacity increase as depth increases. -

Massive New CT Scanner Assesses Car Crash Data
cartechboy writes "If you've ever been in a serious car accident, you've probably had a CT scan to give doctors a clearer idea of your injuries. Soon, your car might get a CT scan, too. Scientists at the Fraunhofer Institute have developed a giant new CT scanner (dubbed, yes, XXL CT) that can scan very large objects, like cars. It Turns out a CT scan of a post-crash vehicle offers an unprecedented precision look at the internal damage details, without disturbing the wreckage further. A crashed car is hoisted onto a turntable, and as it turns, two X-ray detectors on either side scan it. Then multiple images are merged into a single, three-dimensional CT scan. The scanner also can handle airplane wings and shipping containers, which means there may be possible anti-terrorism uses in the future." -
Germany Produces Record-Breaking 5.1 Terawatt Hours of Solar Energy In One Month
oritonic1 writes "Germany is rapidly developing a tradition of shattering its own renewable energy goals and leaving the rest of the world in the dust. This past July was no exception, as the nation produced 5.1 TWh of solar power (PDF), beating not only its own solar production record, but also eclipsing the record 5TWh of wind power produced by German turbines in January. Renewables are doing so well, in fact, that one of Germany's biggest utilities is threatening to migrate to Turkey." -
German Scientists' Visible Light Network Hits 3Gbps
Mark.JUK writes "Scientists working at Berlin's Fraunhofer Heinrich Hertz Institute have developed new components that can turn standard 'off-the-shelf' LED room lights into an Optical Wireless Local Area Network (OWLAN) that delivers data transmission rates of up to 3Gbps. The new kit is an extension of HHI's earlier work, which in 2011 delivered the first 800Mbps capable network using ordinary flashing LED lights. Since then the kit has been improved to achieve a transmission rate of 1Gbps per single light frequency (basic LEDs usually use up to three light frequencies) and the operating bandwidth has been pushed to 180MHz from 30MHz." -
Pinhead-Sized Implant Could Replace Hearing Aids
An anonymous reader writes "Depending on the level of hearing impairment, conventional aids may not be good enough and a hearing implant is the only option. Until now the required surgery to fit them has taken several hours. However, that is about to change. A new implant that can be fitted with outpatient surgery has been developed consisting of a 1.2mm electro-acoustic transducer, which is positioned at the so-called 'round window,' which is where the middle and inner ear connect. It then produces amplified mechanical vibrations that stimulate the auditory nerve. Even though the transducer is tiny, it can reach volumes of up to 120 decibels." -
Power Plant Converts Fruit and Veggie Waste Into Natural Gas For Cars
Zothecula writes "Some readers might remember the Mr. Fusion unit in Back to the Future that Doc Brown fills with household garbage, including a banana peel and some beer, to power the iconic time-traveling DeLorean. While we're still some way from such direct means of running our cars on table scraps, researchers at Fraunhofer have developed a pilot plant that ferments the waste from wholesale fruit and veg markets, cafeterias and canteens to make methane, which can be used to power vehicles." -
800Mbps Wireless Network Made With LED Light Bulbs
Mark.JUK writes "German scientists working at Berlin's Fraunhofer Institute for Telecommunications have set a new world record for Visible Light Communication technology after they succeeded in using regular red, blue, green and white LED light bulbs as the basis for building a new 800Mbps capable ultrafast Wireless Local Area Network. Dr. Anagnostis Paraskevopoulos explained: 'With the aid of a special component, the modulator, we turn the LEDs off and on in very rapid succession and transfer the information as ones and zeros. The modulation of the light is imperceptible to the human eye. A simple photo diode on the laptop acts as a receiver. The diode catches the light, electronics decode the information and translate it into electrical impulses, meaning the language of the computer.' The solution, which could be installed on ceilings and would cover approximately 10 square meters, would be ideal for HD video streaming and inside Hospitals or Aircraft where traditional Wi-Fi is often banned. However visible light signals can easily be blocked, such as when a hand is passed in front of the transmitter." -
Smart Self-Service Scales
Roland Piquepaille writes "German researchers have developed intelligent self-service scales for supermarkets, able to recognize fruit or vegetables placed on them (photo). The scales automatically recognize the item being weighed and ask the customer to choose between only those icons that are relevant, such as various kinds of tomatoes. The scales are equipped with a camera and an image evaluation algorithm that compares the image of the item on the scale with images stored in its database. Store managers can add items to the database. The scales are now being tested in about 300 supermarkets across Europe." -

Shredded Secret Police Files Being Reassembled
An anonymous reader writes "German researchers at the Frauenhofer Institute said Wednesday that they were launching an attempt to reassemble millions of shredded East German secret police files using complicated computerized algorithms. The files were shredded as the Berlin Wall fell in 1989 and it became clear that the East German regime was finished. Panicking officials of the Stasi secret police attempted to destroy the vast volumes of material they had kept on everyone from their own citizens to foreign leaders." -
Computers That Feel our Mood
Roland Piquepaille writes "It certainly happened to you to be so frustrated by the 'reactions' of your computer that you wanted to break it. And the computer industry has noticed, trying to build hardware and software as user-friendly as possible. Still, it would be a good idea for your computer to guess when you're about to become mad at it. Researchers at the Fraunhofer Institute in Germany are working on computers that estimate our emotions. Their solution involves cameras and image analysis, but also special gloves equipped with sensors to record your heartbeat and breathing rate, your blood pressure or your skin temperature. And even if it's difficult to train a computer to interpret emotions, they have enough confidence in their system to demonstrate it at the next CeBIT in March 2006." -
Heliodisplay In Production
David writes "News of a 3D display that projects an interactive image into thin air, the Heliodisplay, is not exactly fresh. What is new however, is that this once far-fetched conceptual object is now real, working and being sold. For those of you who have forgotten, the Heliodisplay from company IO2Tech projects into the air (without a need for special screen) images fed to it from a variety of sources. In a way, it's a working version of R2D2s holographic projection system." A similar product, the Pocket Beamer was previously covered on Slashdot. -
'MP3' Celebrates its Tenth Anniversary
Sachin Garg writes "The Data Compression News Blog reports that on July 14th 2005, the name "MP3" celebrates its tenth anniversary. On this day back in 1995, the researchers at Fraunhofer Institute for Integrated Circuits IIS decided to use ".mp3" as the file name extension for their new audio coding technology. Development on this technology started in 1987, in 1992 it was considered far ahead of its times, then MP3 became the generally accepted acronym for the ISO standard IS 11172-3 "MPEG Audio Layer 3" and no other coding method so far (2005) could uncrown MP3 as the popular standard for digital music on the computer and on the Internet." -
German Robot Dogs Dominate 2005 RoboCup U.S. Open
fishdan writes "As reported over on Sportsdot, the 2005 RoboCup US Open wrapped up today in Atlanta, Georgia. The American entry from the University of Texas fell 2-0 in robot soccer to the powerhouse German squad, the MicroSoft HellHounds. After the match, the German robot dogs were programmed to flex their metal biceps. With the time to devote to development and the financial backing of a company like Microsoft, the German entries are much more polished then their American counterparts at the moment. Last month at the RoboCup German Open, the Germans dominated nearly every category. (Slashdot has covered Robocup in previous years, too.)" -
The Future of Digital Audio
Andru Edwards writes "It can be said that the current digital music scene can be a bit overwhelming with all the competing technologies and file formats. No matter what format you use, these fairly new compression methods make it easy to carry along your entire music collection with you wherever you go, surpassing anything we could have done a decade ago. So where are we headed? This article examines what the future of digital music will bring, both from the hardware and software perpectives." -
A Projection Display For Your Pocket
lub writes "The German Fraunhofer-Instituts für Siliziumtechnologie is developing a pocket beamer. It uses a laser beam and a rotating mirror to display the image. Another laser and a photo diode is used to verify whether the displayed image is shown correctly, so the electronics can adjust the image when the beamer moves. No colors yet; 320x240 in nice shades of red is what they have now, but higher resolutions and color might be implemented later. I want this in my BlackBerry!" -
