      Introduction to measurement microphones (31/08/2017)

      Like all technological devices, loudspeakers, headphones, MEMS microphones, sonar emitters and police sirens all need to be measured and tested, both during design and production. Furthermore, products that generate any noise at all (such as motors, airplanes, wind turbines, coffee makers or HVAC) are often measured for safety or environmental impact, or are continuously monitored, listening for signature acoustic signals that indicate correct performance – or failure.

      Powering and protecting LED lighting (31/08/2017)

      From high bay and architectural lighting to outdoor street lighting, and even 75W incandescent bulb replacement, LEDs are fast becoming the lighting source of choice – despite costing more than incandescent lighting by a factor of 13! This article discusses why this is, and considers what LEDs need to power them – and also, how to protect them from the hazards they face within their respective implementations.

      Experience solves legacy test problems (25/08/2017)

      The test function has always been among the most challenging processes in electronics manufacturing. How can test equipment keep ahead of the sub-assemblies it needs to validate? In theory, it should be easier when testing legacy products, but successfully developing futureproof solutions requires not only knowledge of the new, but also experience of the old.

      Problematic pacemakers (25/08/2017)

      During the French Revolution, beheading was the preferred method of execution. The guillotine was used for thousands of executions, meaning there was no shortage of experimental material for biologist Marie Francois Bichat. Bichat tested the electrical stimulation of hearts, which was instrumental in the development of the modern day pacemaker. Nowadays, pacemakers are commonly used to maintain a regular heart rate. This article looks at how electrical interference can led to pacemaker issues.

      Power quality in the medical sector (25/08/2017)

      You may have seen more people in your social news feed checking in to A&E or posting selfies from their hospital bed recently. It’s not that all your Facebook friends have suddenly been under the weather: hospital patients and visitors are now allowed to use mobile phones on site, without fear of interfering with medical equipment. However, hospitals still have a long way to go to mitigate power quality issues.
