Tag Heuer's US$6200 Meridiist mobile phone handset
If your Swiss watch has been complaining that it doesn't want to be seen in public with your mobile phone any more, you could do worse than check out Tag Heuer's first foray into the handset market. The Meridiist will feature high-grade steel casings, unscratchable dual crystal displays and nearly a month of standby time. Naturally it looks very classy too, but at up to US$6200, without any mention of 3G connectivity, it could be more a piece of palm jewelery than a serious telephone.

HTC Shift: ultra-compact, dual-interface mobile computing
With a form factor that sits somewhere between a fully-fledged laptop and a pocket-size PDA, the light weight HTC Shift mobile PC offers a full QWERTY keyboard and a 7-inch "slide-'n-tilt" touch-screen interface backed by Wi-Fi and HSDPA/3G connectivity, a 40-gigabyte hard drive, two days standby battery life and a handy "always-on mode" that allows access to emails and other features without the need to fully boot up the device.

Volkswagen demonstrates fully-automatic reverse parking system
Minor collisions as a result of parking mishaps are a common, costly and extremely frustrating occurrence and for several years auto manufacturers including BMW have indicated that solutions that take human error out of the equation are on the way. The latest news in the area comes from Volkswagen, which has demonstrated its "Park Assist Vision" system at this year's Hanover Fair. The fully-automatic, remotely-operated self-parking system lets you get out of the car and watch as it backs itself into even the skinniest of perpendicular spaces, using cameras located in the left and right exterior mirrors to gauge the dimensions of the parking area available and communicate this information to the computerized steering and drive systems.

Beijing's gargantuan Capital International Airport
Terminal 3 of the Beijing Capital International Airport became fully operational on March 26, becoming the largest airport terminal complex built in a single phase. The US$3.5 billion expansion commenced in March 2004, and the 986,000 square meter airport can now absorb all five of Heathrow's terminals with 17% left to spare.

The world's fastest grass muncher?
If you're looking for a lawn-mower to park in the garage beside your Bugatti Veyron, the Excalibur may be just the ticket. Billed as the world's fastest lawnmower by its Indiana based manufacturer Dixie Chopper, the Excalibur 3874 promises to manicure 9.2 acres per hour at speeds of up to 15mph.

Tests demonstrate effectiveness of BioSentry water monitoring system
The World Health Organisation states that one billion people lack access to clean drinking water, and the Intergovernmental Panel on Climate Change believes this number will rise. In the developed world, the issue is one of monitoring and maintaining the fresh water supplies that already exist, and that's where systems like JMAR Technologies' BioSentry water monitoring system come in. Biosentry uses laser-produced, multi-angle light scattering technology to identify individual microorganisms, eliminating the need for consumables or reagents and is able to detect bacterial pathogens up to 25 times better than any other water monitoring system according to recent test results from the U.S. EPA.

Thermador electric cooktops with infrared sensor technology
Thermador's latest range includes electric cooktops with sensor technology that uses an infrared beam to continuously monitor the heat from the cookware itself and automatically maintains precise cooking temperature to help save time and effort in the kitchen.

H2Origin demonstrator vehicle achieves 300km range
A three year collaborative research project by PSA Peugeot Citroën and fuel cell specialist Intelligent Energy has born fruit in the form of the H2Origin demonstrator vehicle, a battery-electric vehicle that uses a specially designed hydrogen fuel cell to triple its range to an impressive 300km (186 miles). The hydrogen storage system developed for the zero-emission demonstrator vehicle, which is based on the Peugeot Partner Origin van, is compact enough to squeeze under the bonnet and utilizes a swappable storage rack of compressed hydrogen tanks that slide out the rear, by-passing the need for a conventional fuel station and therefore simplifying the infrastructure needed to make hydrogen-powered vehicles a commercial reality

Mitsubishi Lasers in on Hi-Def TV
The first-ever laser-powered television, LaserVue, is being rolled out by Japanese electronics giant Mitsubishi, which says laser beams provide the widest range of rich, complex colors, along with the most clarity and depth of field, and will deliver a range of color never before seen in home entertainment. LaserVue's new features include the latest generation of TI's DLP chipsets, and completely eliminate the color wheel and lamp found on regular DLP HDTVs. The TV cabinet size and depth will also be reduced over standard DLP models. Mitsubishi says current HDTVs display less than 40 percent of the color spectrum visible to human eyes, and that its product offers twice the color gamut of either LCD or Plasma TVs.

Which is the Better Motion Sensor: MEMS Sensor or Camera?
An article from TechOn! compares the motion sensing capabilities of both a MEMS sensor and a camera. Motion sensing is generally done with two methods: the MEMS (microelectromechanical system) method using acceleration and angular velocity sensors, and another method that comprehends motion from changes in images of surroundings captured by CCD, CMOS and other camera systems. According to Hiroshi Usuda from Usuda Research Institute & Systems Corporation Ltd, both methods have their own unique benefits and drawbacks. While MEMS sensor technology allow tens of thousands of signals to be processed every second and provides more accurate recognition of motions, camera-based methods will keep costs down because there is no need to add new hardware to mobile phones.

New Laser is "Brightest in the Universe"
The world's most powerful laser, the pulses from which are more intense than any known light source in the universe, has been developed by researchers at the University of Texas, USA, who say the temperatures and pressures it generates when it hits a target will let them explore conditions found in exploding stars and the cores of giant planets. The laser can blast out infrared pulses of more than one petawatt—one million billion watts—of power, far more than the output of all the world's power plants put together, a sum measured in terawatts, or trillions of watts. In the 1990s, the now-defunct Petawatt laser at the Lawrence Livermore National Laboratory achieved pulses of more than one petawatt, but the Texas Petawatt Laser is expected to eventually produce pulses of 1.4 petawatts. The energy contained in each pulse is only about 200 joules, according to the researchers, as much as a light bulb consumes in a few seconds, but the energy is packed into a very brief pulse just one-tenth of a trillionth of a second long, which makes it vastly more powerful.

Thinking Machines from Algorithms and Microprocessors
An algorithm similar to the one governing human cognitive abilities may be the key to true thinking machines, according to the startup firm Numenta, headed by Jeff Hawkins, creator of the Palm Pilot and Treo. Because human brains work in parallel, in contrast to serially calculating computer processors, Numenta believes computers can get close to the processing power of brains if the software architecture is based on the cerebral cortex. Scientists hope that artificial brains of software and silicon will produce more powerful computers, as well as insights into the structure of human brains and consciousness. Read more

Using Spectral Data and Neural Networks to Measure Flame
Using the multilayer perceptron neural network to translate the spectral data into thermal data, scientists from the Universidad Carlos III of Madrid, Spain are studying the use of optical techniques for the measurement of parameters, mainly the temperature of a flame, in combustion processes. Researchers hope to control the parameters automatically, reduce contamination and increase efficiency. The scientists use computer simulations of optical techniques, in particular the infrared emission spectroscopy of the gases produced in the reaction, such as carbon monoxide (CO) or nitrogen oxides (NOx). The spectral information is mathematically related to the temperature of the flame, researchers say, allowing for its calculation inside a combustion chamber. Since the spectral measurements are taken in high definition, the required calculations for their interpretation using "machine learning" techniques is very high, reducing performance. Although a lot of spectral data is required to evaluate the spectrum accurately, researchers say the excess of information is not suitable for a neural network approach. Read more

Technology Turns Thought Into Action
Using computers for checking e-mail, drawing images and playing games seem like common tasks for most people. For the severely paralyzed, however, these undertakings can be beyond their reach. New research in neurotechnology and deep brain stimulation, where medical devices are placed on the brain in an effort to control bran activity, could be changing that. By converting brain signals into action, BrainGate, a neural interface system developed by Cyberkinetics Neurotechnology Systems, is helping participants perform tasks such as moving a cursor or spelling out words on a monitor with only their thoughts.

A Brainy Approach to Image Sorting
Teams of researchers at Honeywell, Teledyne Scientific & Imaging and Columbia University in New York, USA are developing a way to combine the speed of a computer with the sensitivity of the human brain when it comes to identifying and sorting images. The researchers are hooking image analysts up to EEG machines, reading their brain activity, and speeding up data sorting by up to six times the rate of humans. According to Deniz Erdogmus, a computer science professor collaborating on the project, the system could be used for searching desired images in a large database and would be much faster than a manual search. While it takes 300 milliseconds (ms) for a human to consciously recognize specific information in a picture and another 200 ms for that person to react to the image, there is actually electrical activity in the brain's visual cortex about 150 ms after seeing an image. This activity, called an event related potential, is what the researchers are trying to isolate and take advantage of in their ongoing research. Read more

The Future of Digital Signal Processing Could Be DNA
Performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future, according to researchers writing in the March 2008 edition of Proceedings of the IEEE, whose research includes studying the use of DNA for digital signal processing. DNA strands can be used as input and processing elements, and is an excellent medium for data storage. According to the researchers, digital samples recorded in DNA can be kept in a liquid form in test tubes to save space, are easily replicated using common laboratory techniques, and would allow for an easily searchable database, regardless of size. Using bacteria to process signals has spurred a competition - the International Genetically Engineered Machine Competition at the Massachusetts Institute of Technology, USA, where undergraduate students compete to design biological systems that can perform simple computations. In 2005, a group of students modified E. coli cells to react to light and created a layer of these bacteria that could perform edge detection of an image, a basic processing task. Read more
