Fraunhofer IIS presented the first DRM chip design for car radios. This car radio solution will enable drivers to select their preferred radio program from hundreds of different radio stations. However, it is something more than purely listening to favorite music: the new radio formats offer multilingual support to ethnic news or talk programs. In this way, drivers will get local news or may listen to programs in foreign languages – at any time and any place.
With the international CES exhibition in Las Vegas on January 6 - 9, 2005, the vision of Digital Radio Mondiale DRM car radios got one step closer to reality. Based on Philips‘ ”SAF7730” digital car radio platform, Fraunhofer Institute for Integrated Circuits IIS presented the first DRM implementation that seamlessly fits into today’s car radios. For the OEM, upgrading to the international DRM standard is just a matter of inserting a ”DRM module” into an existing connector slot. Initially, the ”DRM module” upgrade allows to differentiate products with minimum investment, risk and time to market. In the next stage, the evolving road maps with fully integrated ”DRM car radio chip sets” will lower the system cost further, completely inline with the requirements of the mass market.
The DRM standard applies the latest advanced audio coding algorithms for music and speech transmission – to provide FMlike sound quality at very limited bandwidth. DRM programs are digitally transmitted and highly compressed. Therefore, they may be stored on-the-fly in the car radio’s memory, to build up a personal music collection. In addition, DRM programs carry other types of multimedia content and information, including headline news or traffic and tourist information. This data is transmitted in the background and will be immediately available after one gets into the vehicle.

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
