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
[ + ]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?
[ + ]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
[ + ]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
[ + ]Mutton dressed as lamb (Part 1)
With the advent of faster FPGAs with sizeable quantities of RAM, it's becoming possible to breathe new life into old micro designs whose days would otherwise be numbered
[ + ]Battery breakthrough puts NZ on the map
Two electrochemists at Massey University have come up with a formula that could rock the foundations of the $200 billion global battery market. Keith Newman backgrounds this new 'disruptive technology'
[ + ]Silencing the silent service
It is well known that the first few Collins class submarines suffered from a higher level of noise emissions at the beginning of their service life than was desirable. The good news is that the early issues are being successfully corrected.
[ + ]Minimising errors in low resistance measurements
This article looks at variables in measuring low resistance values and the errors that may occur in making those measurements
