Technical article: Mike Might Know — semiconductor strain sensors download

Sherborne SensorsTue, 21 Oct 2014

Apart from its originally intended purpose for strain measurement, the metallic resistance strain gauge is extremely commonplace in transducer applications. Its low cost, high accuracy and ease of application make it an ideal transduction element and it is widely used in pressure, load, force, torque and displacement transducers. However, this article in Sherborne Sensors’ ‘Mike Might Know’ series focuses on semiconductor strain sensors.

Data centre and server security

Technical article: 21st century technology catches up with access control in data centres downloadweblink

EMKAThu, 9 Oct 2014

There have been several breaches of security at high-profile institutions in recent times, and almost every day brings a new story of how a building has been compromised and critical data or hardware destroyed or stolen. Data centre operators have long understood the need for physical access control on server cabinets. There are many ways of securing data centres, and many solutions have evolved over time to address access control at doors and server cabinets.

Audio precision 2722 analyser measures oscillator THD at –110dB, about 3ppm

Application note: fidelity testing for A→D converters download

Linear TechnologyMon, 29 Sep 2014

According to Linear Technology’s Jim Williams and Guy Hoover, the ability to faithfully digitise a sine wave is a sensitive test of high-resolution A?D converter fidelity. This test requires a sine-wave generator with residual distortion products approaching one part-per-million. Additionally, a computer-based A?D output monitor is necessary to read and display converter output spectral components.

Application note: closed-loop 100A active load brute force marries controlled speed download

Linear TechnologyWed, 24 Sep 2014

Digital systems, particularly microprocessors, furnish transient loads in the 100A range that a voltage regulator must service. Ideally, regulator output is invariant during a load transient. In practice, some variation is encountered and becomes problematic if allowable operating voltage tolerances are exceeded; 100A load steps exacerbate this issue. To meet this need, a closed-loop, 500kHz-bandwidth, linearly responding, 100A-capacity active load is used.
