| Open-sourcers launch campaign to weaken European patents |
A group of companies promoting open-source software launched a campaign
in Europe Wednesday that is designed to bolster the use of copyright law
at the expense of patent law in a move they believe will help safeguard
the spread of open-source software. The initial corporate backers of the
campaign, called NoSoftwarePatents (NPS), are Red Hat, MySQL, and 1&1.
Large established corporations generally resort to patent protection to
protect their positions over newer and smaller companies, e.g.,
open-source firms. The issue figures directly into IT organisations
moving towards open-source software, whose migration efforts are slowed
because of the copyright-patent debate.
The NSP campaign will attempt to influence 12 major European countries
to work to water down patent protection for software. The campaign seeks
to eventually influence pan-European patent agencies, including the
European Patent Convention to promote new legislation. The final goal is
to help spread open-source software by removing onerous IP regulations. |

| Miniature jet engines could power cellphones |
Engineers of the Georgia Institute of Technology, US, have moved a step
closer to batch producing miniaturised, jet engine-based generators from
a single stack of bonded silicon wafers. These chip-based 'microengines'
could one day power mobile electronic devices.
By spinning a tiny magnet above a mesh of interleaved coils etched into
a wafer, the researchers have built the first silicon-compatible device
capable of converting mechanical energy - produced by a rotating
microturbine - into usable amounts of electrical energy. It produces 1.1
watts of power, already enough to power a cellphone or GPS receiver, and
it is just in the research stage. Achieving this power requires 100,000
revolutions per minute.
The key advantage of microengines is that they pack in at least 10 times
more energy per volume of fuel than conventional lithium batteries, take
up less space and work more smoothly than much-touted fuel cells. |

| NEC strikes blow in supercomputer battle |
The battle for supercomputing supremacy took a new twist on Tuesday when
Japanese manufacturer NEC launched a new generation of computational
building blocks that could be laced together to form the most powerful
supercomputer in the world.
NEC will sell single SX-8 'nodes' for about $11,000. Each node is
capable of 128 gigaflops (128bn floating point operations per second).
But the company says that if 512 of these units were laced together, the
maximum number, the result would be a supercomputer capable of a massive
65 teraflops - 80 per cent faster than its nearest rival.
On 29 September, IBM's 'Blue Gene' knocked NEC's Earth Simulator from
first place in the world rankings, performing at a speed of 36 teraflops
during a standard benchmark test. The Earth Simulator, built from an
array of NEC SX-6 nodes, had been the defending champion since June
2002. NEC is now seeking to regain its crown with this new set of
building blocks that are smaller, faster and less power-hungry than
those used in the Earth Simulator. |

| Smart fabrics make for enhanced living |
Imagine a handbag that warns you if you are about to forget your
umbrella or wallet, and which you can later turn into a scarf that
displays today's pollution levels.
All these objects could soon be possible thanks to a system of
computerised fabric patches developed by MIT's Media Lab. Each patch
contains a functional unit of the system - a microprocessor and memory
plus either a radio transceiver, a sensor, a microphone, batteries or a
display. Put the patches together in different ways and you can create a
variety of information-providing or environment-sensing objects.
To keep it waterproof, the circuit board inside a patch is coated with a
hard transparent resin. It is then padded with a thin layer of foam and
encapsulated in the chosen fabric. It can be populated with a variety of
components, from Bluetooth transmitters to a cut-down PC motherboard.
The patches are joined using Velcro, which has been modified to enable
electrical as well as physical connections. In this way, data and power
can flow from one module to the next. |

| New display 'as clear as a glossy magazine' |
Hewlett Packard has developed a revolutionary liquid-crystal display
technology which it hopes will ultimately lead to ultra
high-resolution flat screens ranging in size from a magazine page to an
advertising billboard. Moreover, the screens will use far less power
than ordinary LCD screens, and can be made using cheap technology.
Conventional computer screens can only manage 1600 by 1200 pixels, and
even high-definition TV displays create their images with an array of
1920 by 1080 pixels at best. Now, HP reckons it can make an A4-sized
screen with 7000 by 5000 pixels - matching the quality of a glossy
magazine. HP says it will be able to replicate this quality on screens
all the way up to large electronic posters and billboards.
HP calls the new system a post aligned bistable nematic (PABN) LCD. This
week, HP demonstrated two 4 by 3-centimetre prototypes. The images on
the prototypes were undeniably coarse, with visible blemishes and faulty
pixels. But HP stressed that PABN will not be ready for market any time
soon. Rather, the demonstration is proof that the technology works. |

| Printers betray document secrets |
That staple of crime novels - solving a case by identifying the
typewriter used to write a ransom note - is being updated for the modern
day. Scientists at Perdue University in Indiana have discovered that
every desktop printer has a signature style that it invisibly leaves on
all the documents it produces. The work will help track down printers
used to make bogus bank notes, fake passports and other papers.
Before now it was thought that the differences between cheap,
mass-produced desktop printers were not significant enough to make
individual identification possible. But the researchers have developed
techniques that make it possible to trace which printer was used to
produce which document.
The differences emerge in the way that a laser printer lays down ink on
the paper and which can be spotted with the Purdue system. Typically,
different printers lay down ink in distinct bands that can be spotted by
image processing software. The team is now working to extend its
techniques to cover inkjet printers and on ways to manipulate printers so
they lay down ink with more easily identifiable signatures. |

| Hollywood chip will bring digital TV to mobiles |
Texas Instruments (TI) announced details of a wireless chip on Thursday
that will let mobile phone users watch high-definition television on
their handset.
Codenamed 'Hollywood', the chip will support two emerging digital TV
standards - Digital Video Broadcasting - Handheld (DVB-H), a European
specification that should also be deployed in the US; and Integrated
Services Digital Broadcasting - Terrestrial (ISDB-T), a similar Japanese
spec. At present, a mobile phone manufacturer would have to include
three separate chips - a TV tuner, a signal demodulator and a channel
decoder. The Hollywood chip includes all this functionality.
Texas Instruments said that the chip will be able to receive a live TV
broadcast at up to 30 frames per second. But Hollywood is some distance
away from commercial deployment. TI says it is already being trialled
but manufacturers are not expected to receive samples until 2006. There
will also need to be significant advances in battery technology, as
digital TV will be a big drain on a mobile's power resources. |

| New gadget turns off TVs |
A new keychain gadget that lets people turn off most TVs - anywhere -
has become an instant best-seller. Inventor Mitch Altman's TV-B-Gone
says orders are pouring in so fast his website keeps crashing.
Hundreds of orders came in after the tiny remote control was mentioned
in Wired magazine and other online media outlets. The keychain fob works
like a universal remote control but one that only turns TVs on or off.
With a zap of a button, the gizmo goes through a string of about 200
infrared codes that controls the power of about 1,000 television models. |
