Spread spectrum sensor technology blazes new applications
There are probably hundreds of variations of capacitance sensors in use today, as any quick patent or literature search will quickly reveal
[ + ]Tracing intermittent electrical faults
There's probably not a service engineer on the planet that wouldn't agree that intermittent electrical faults are the most difficult to trace. Although these may seem like random disasters, invariably they have a sound physical cause
[ + ]Molecular switches that assemble themselves
"Smaller means faster and more efficient" is the maxim of the electronics industry as it strives towards the greater miniaturisation. Conventional fabrication methods are reaching their limits, with the production of components around 100 nm in size
[ + ]Data, data everywhere
In today's dynamic telecoms environment the equipment loads on a DC power system and battery may be regularly increased through its life
[ + ]All aboard - So long as you have a card
Following tests, an electronic fare-management system is set to revolutionise public transport. With the EasyRide program, a special chipcard is all you need to travel from one end of the line to another
[ + ]Over reliance on patches?
Business needs to adopt a more holistic approach to security instead of relying on quick-fix patches to combat network attacks according to Top Layer Networks, Australia and New Zealand manager, David Britt. While patches may be an time saving necessity, they do not solve the underlying issues associated with network security in the same way as preventative measures, “there needs to be a much stronger emphasis on planned security measures, with an increasing focus on preventative infrastructure rather than ‘prescription-style’ cures,†Britt said.
[ + ]Wafer level reliability testing of semiconductors
As semiconductor devices shrink in size and become more complex, it has become necessary for fabricators (fabs) to use more parameters to monitor and control production processes
[ + ]ICs help implement a trim-Free VCO (Part 2)
A new family of integrated circuits can ease the task of developing compact, fixed-frequency, voltage-controlled oscillators (VCOs) for IF applications
[ + ]Determining accuracy in EMI measurement systems
During the last few years, EMI (electromagnetic interference) regulations have been introduced in most developed countries. Compliance with regulations generally requires type testing for emissions and immunity
[ + ]Connector pin recession and network analyser accuracy
The apparent effect of a recessed connector on network analyser measurements is often talked about, but without any quantitative measurements it is very hard to either predict or correct for the resulting errors
