World record 10.4 Gigabit wireless transmission: "University of Essex21.06.2005?World record 10.4 Gigabit wireless transmission Researchers at the University of Essex are claiming a world record for the amount of computer data sent over a point-to-point wireless channel.
The results achieved by the team from the Department of Electronic Systems Engineering are the equivalent of more than 162,000 phone calls or over 10,000 broadband internet connections being made simultaneously. Such large capacity could revolutionise wireless internet download times for many households and local businesses, small and large.
While the techniques used by the Essex group don%u2019t fit exactly to the MultiBand Alliance template in the IEEE (Institute of Electrical and Electronics Engineers) 802.15 ultra-wideband radio standardisation process, they are important because they show that 10 Gigabit radio is feasible. The successful experiment at Essex demonstrates that far greater capacity could be obtained from present generation wireless links given appropriate standardisation.
The Essex Department of Electronics Systems Engineering is one of the strongest in the country, and currently has a grade 5 rating for carrying out research of national and international excellence. In 2001, researchers in the department achieved a world record for the amount of computer data sent over a single multimode optical fibre, which won them a slot in the Guinness Book of Records.
The latest record-breaking results came at the end of a two-year project by MSc student Terry Quinlan, part of precursor work which will be further enhanced by a recently-announced ?1 million Higher Education Funding Council for England equipment award. Eventually, the mm-wave region could be used where even higher data rates may be possible.
Head of the Essex project, Professor Stuart Walker, said: %u2019This achievement represents the culmination of many months of painstaking work. Multigigabit transmission systems of any sort require really detailed design and wireless is no exception. The original aim was just to investigate the performance of cheap flat patch antennas. We were pleasantly surprised by the initial results and kept on improving the experimental set-up. "

Will Knight Billions of tiny mechanical levers could be used to store songs on future MP3 players and pictures on digital cameras.
As bizarre as the idea might sound, researchers at a Dutch company have already demonstrated that miniscule mechanical switches can be used to store data using less power than existing technologies and with greater reliability.
Nanomech memory, developed by Cavendish Kinetics in the Netherlands, stores data using thousands of electro-mechanical switches that are toggled up or down to represent either a one or zero as a binary bit. Each switch is a few microns long and less than a micron wide - roughly a hundred times smaller than the width of a human hair.
Existing computer memory typically stores data as an electrical or magnetic charge. Cavendish Kinetics claims Nanomech memory can read and write data using 100 times less power than such systems, and works up to 1000 times faster. It is also much more resilient to both temperature and radiation, the company claims.
Intermolecular forces
Nanomech memory incorporates hundreds of thousands of conductive metal levers, each just a few microns long. These are created by lithographically etching a design onto a template and then chemically dissolving away unwanted layers."

Mighty Morphing Power Processors: "Mighty Morphing Power Processors IBM and others are racing to create chameleon chips that change to suit the job
Even by the standards of the Lone Star State, the claim by two Texas researchers -- Douglas C. Burger and Stephen W. Keckler -- can seem a trifle grandiose. 'We're reinventing the computer,' asserts Keckler.
A glance at their backers, though, dispels some of the skepticism. IBM (IBM
) is working closely with the two University of Texas computer scientists. And the Pentagon's Defense Advanced Research Projects Agency in 2001 handed them $11 million in development funds. Now, IBM is gearing up to manufacture the first prototype of their concept for a radically new computer-brain chip. If it delivers what Burger and Keckler promise, high-tech gurus are betting it will spawn a new family of superchips from Big Blue -- chips capable of crunching a trillion calculations every second.
Such blistering speed would itself be amazing; it's roughly the oomph of a $50 million supercomputer in 1997. But more impressive, the chip can rewire itself on the fly -- a feat known as reconfigurable computing. With this technology, a future Macintosh from Apple Computer Inc. (AAPL
) might rejigger the circuitry on its PowerPC chip and then run software written for Intel (INTC
) Corp.'s microprocessors. Or an iPod music player could turn into a handheld computer -- or detect an incoming call and convert itself into a cell phone.
IBM is hardly the only chipmaker chasing morphing semiconductors. Virtually every major supplier of so-called logic chips is working on some such notion, including Hewlett-Packard (HPQ
), Intel, NEC (NIPNY
), Philips Electronics (PHG
), and Texas Instruments (TXN
). A dozen or more startups are in the race as well, including Velogix, picoChip Designs, and MathStar."

Perpendicular recording: Why it matters - page 2 | Perspectives | CNET News.com: "Fifty years ago, when the first 5MB drive was introduced, few if any observers could have predicted the current state of the industry. They would likely not have believed that a read/write head could fly 100mph over a spinning platter at a distance that is less than 1/10,000th the width of a human hair. Or that hard drives the size of matchbooks would be capable of storing entire music libraries. This all would have been in the realm of science fiction.
Yet they would likely understand the scientific concepts and physical laws that have made these advances possible. While there has been a great deal of invention, the basic science--like Danish inventor Valdemar Poulsen's discovery of magnetic recording more than 100 years ago--has remained relatively constant.
Such constancy gives rise to confidence across the industry that the challenge of superparamagnetism will be met. Perpendicular recording is most likely the first technology bridge in this realm, but it is by no means the last."
