NPL, in collaboration with Surrey University, has developed a compact 
Electronically Steerable Parasitic Array Radiator antenna (ESPAR). 
Technology&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 

ESPAR technology is well known in the relevant scientific and user 
communities but not yet widely adopted as a commercial product. ESPAR antennae 
maximise the radiation towards the desired users and nulls towards the sources 
of interference, which improves the bandwidth and range for wireless 
communications and related applications. These devices are inherently more 
expensiv...]]></description><pubDate>Fri, 14 Oct 2011 02:15:23 GMT</pubDate><author>peter.benson@npl.co.uk</author><guid>http://npl.technologypublisher.com/technology/8042</guid></item><item><title>A 3D vibrating micro-CMM probe</title><caseId>MP005</caseId><link>http://npl.technologypublisher.com/technology/8041</link><description><![CDATA[

A novel micro-scale 
co-ordinate measuring machine (CMM) probe designed for use on CMMs for miniature 
parts. The probe is designed to overcome many of the adverse effects experienced 
by standard micro-scale CMM probes, while still

A 
portable and passive gas dilutor that is “charged” with a Standard gas mixture 
and when connected onto a cylinder of diluting gas provides a flow of “zero” gas 
and seven selectable dilutions of the Standard mixture.


&nbsp;
Main 
Features
&nbsp;


The 
AGS is portable, rugged, weather proof and requires no power, so is 
intrinsically safe. Little Standard gas is consumed due to the high dilution 
ratios of ~1:1000.


&nbsp;
Applications
&nbsp;


The AGS is ideal for 
in-fi eld calibration and linearity testing of gas analyzers and some laboratory 
applications, especially to provide low...]]></description><pubDate>Fri, 14 Oct 2011 01:56:49 GMT</pubDate><author>peter.benson@npl.co.uk</author><guid>http://npl.technologypublisher.com/technology/8040</guid></item><item><title>Pump Cavitation Detection</title><caseId>MP004</caseId><link>http://npl.technologypublisher.com/technology/7957</link><description><![CDATA[Remote detection of incipient cavitation (vapour/gas

The NPL 
CaviMeter™ is the first instrument capable of measuring localised ultrasonic 
cavitation (the implosion of bubbles in a liquid when a high frequency sound 
wave is applied), and will transform the way in which hospitals clean medical 
instruments , and the way in which manufacturers develop foodstuffs, biofuels 
and pharmaceuticals, by providing a new measurement 
capability.
&nbsp;
The 
CaviMeter’s key component is a novel spatially-sensitive sensor that detects 
aultrasonic signals from acoustic cavitation activity in fluids. Coupled with a 
bespoke electronics ...]]></description><pubDate>Mon, 10 Oct 2011 09:21:23 GMT</pubDate><author>peter.benson@npl.co.uk</author><guid>http://npl.technologypublisher.com/technology/7956</guid></item></channel></rss>
