Fuel cell hydrogen promises portability
Engineers at Purdue University have developed a way of producing hydrogen for fuel cells to automatically recharge batteries in portable electronics, such as notebook computers, and eliminate the need to use a wall outlet
[ + ]Let there be light...emitting diodes
Russell Dupuis talks about the development and future of this revolutionary technology in conversation with Jane Sanders
[ + ]More power and name change to GS1
More than 250 delegates attended the two-day event that attracted speakers from countries that included Britain, the US, China and India
[ + ]A bright future for display technologies
The value of worldwide shipments of electronic displays is expected to grow to $114.8 billion by 2006. Yet the price of the displays is continuing to come down and the market for displays will continue to see high growth for many years to come
[ + ]Where a probe is not an echo
Researchers at the University of Southern California's Viterbi School of Engineering have demonstrated a novel high-resolution ultrasonic transmission tomography (HUTT) system that offers 3D images of soft tissue
[ + ]Fans keep their cool with ceramics
DC type cooling fans are essential for many different types of cooling applications, but they do have a relatively short life expectancy when used on products that are designed to operate continuously in hot or hostile environments
[ + ]ABCs of DMMs
How do you make measurements safely? What features do you need? What is the easiest way to get the most out of your meter? Which meter is best suited to the environment you're working in?
[ + ]Close look at power MOSFETs - Part 1
Discrete power MOSFETs employ semiconductor processing techniques that are similar to those of today's VLSI circuits, although the device geometry, voltage and current levels are different from the design used in VLSI devices
[ + ]Can you trust a low-cost battery?
The battery pack is a mystical black box that does not change size, weight and colour during its lifetime. Neither does it reveal the charge level and state-of-health. And yet, the battery plays a key role in many portable applications
[ + ]Test system - a sound investment?
Cochlear faced the challenge of reducing escalating costs and development time for a new generation of hearing implants by creating an automated, mixed-signal test system using off-the-shelf technology
[ + ]Speeding up embedded systems
Embedded products are becoming more complex and are processing more data than ever before. Consequently they require faster means of communication to external systems, compared with traditional methods such as RS232 or RS485
[ + ]Verifying RF transceivers
The global market for portable communication products such as pagers, two-way radios, cordless phones, mobile phones, personal GPS receivers, wireless internet browsers and portable video phones is growing at a rapid pace
[ + ]The light at the end of the tunnel
While enormous machines gouge out 7 m wide tunnels from the hard rock beneath Martin Ams' feet as part of the Epping to Chatswood Rail Line, the Macquarie University PhD student focuses on making tunnels just five microns wide
[ + ]Good vibrations
The cars and aircraft of the future will be safer and the buildings and production lines more efficient thanks to wireless sensors powered by tiny generators being developed at ANU
[ + ]Flat-panel TV is 25% brighter
Agilent has announced a colour management system for backlighting LCD flat-panel TVs that delivers 25% more brilliant colours than current fluorescent backlighting
