Security cameras – it’s all in the technology

  Selecting the right camera for security applications is far more complicated than what one would think. It is not just selecting the right camera; lens technology and image processing technology are also factors to be considered, as well as whether quality pictures are possible in low light conditions; or whether the image processing technology […]

Ultra-low-power MCU modes – efficiencies and obstacles

  The market offers a large range of microcontrollers described as “ultra-low-power” (ULP). These MCUs aim to reduce and optimise the power consumption of all applications, so as to – in the case of battery-operated systems – extend the battery life. Several complying techologies exist: starting from an optimised energy-consuming active mode, to various sleep […]

EMI shielding effectiveness in conductively coated plastics

  Conductively coated plastics are becoming increasingly popular for EMI shielding. Vacuum metallising is a cost effective way to get fast turnaround in small quantities. Commonly, shapes can be complex, making it impossible to get absolutely uniform coatings. The article covers comparative shielding effectiveness (SE) tests on various configurations, primarily to assess the impact of […]

Super-broadband speeds – it’s all in the chip!

  The first deployment of the Infinera DTN-X platform across South Africa will deliver businesses with the simplicity, scalability, and efficiency expected from a fibre network – and it is all in the chip! Internet Solutions (IS), the first in South Africa to deploy the new technology, is now able to react to changing business […]

Electrical systems’ complexity increases the challenges for OEMs

  This abridged White Paper discusses the rising demand for electrical/electronic (E/E) systems functionality in automotive and military/aero vehicles due to customers and legislative requirements. To deal with these complexities would a systems engineering approach not be better to deal with these new demands? In a White Paper by Mentor Graphics “Managing electrical complexity with […]

Power electronics in automotive applications

  Over the last few decades, electrical loads in an automotive system have evolved from lighting and battery-charging towards infotainment, sensors and safety, thanks to component miniaturisation. This has made the car smarter and more fun to drive! While the trend of electronics in infotainment systems continues, a future trend is electronics in power train […]

3D printing technology produced locally

  The 3D printing technology which has revolutionised the design and manufacturing field the world over has also become popular in Africa. Our biggest challenge is that most of these devices originate from overseas, so obtaining one locally is expensive. Now the first locally designed 3D printer will soon be available.

Ambient LED lighting advances in tomorrow’s vehicles

  The advancement of ambient LED lighting solutions stems from the quest by automotive-OEM interior stylists to add value and make their vehicles more appealing while creating a truly positive driving experience and increasing brand awareness. Electronics is the fastest-growing sector of automotive content, over mechanical, pneumatics and hydraulics. With the increasing number of ambient […]

Infrared LED technology for touchscreens

  The advent of high-efficiency infrared LEDs has made intuitive and robust touchscreens for various devices and controllers attractive to both industry and the end-user. Download the Pdf

Antenna matching for RFID reader

This article describes the design method for determining an antenna matching circuit. While there are an infinite number of possible impedance matching networks, this application example focuses on a 50 Ω three element match. A three-element match is recommended as it allows the designer to select the required antenna quality factor, Q, for the application. […]
