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 […]

Are you getting optimum value from your investment in thermal imaging?

  Thermography is not just pointing the camera at an object. You have to know what you are imaging and then how to interpret the image. Thermal imaging is not just about pointing a camera at a switch, a transformer or risky cable connection. As in photography, a “mik en druk”  (point and press) camera cannot […]

VSATs are alive and well and growing

  Optical fibre-centric companies often give the impression that satellite are fading out the picture, but in fact the opposite is true.  Very small aperture terminal (VSAT) services are growing and remain vital in the communication mix. Satellites still remain popular and critical to connecting large parts of Africa where many areas have no access […]

Standards for measuring voice quality

  Hello…hello…can you hear me…hello please can you move to another spot so that the signal can improve. This type of conversation is becoming more the norm than the exception in South Africa lately. With the mobile voice penetration in South Africa being almost 100% it evident that voice traffic is aprominent medium of communication. […]

Modern techniques of verification for wireless M2M communication

  M2M (machine-to-machine) communication brings valuable benefits both to device manufacturers and to end users: remote sensing, monitoring, tracking and data-logging bring a new dimension to the functions of machines in industrial, commercial, military and other market segments, in applications such as automation, vending, smart metering and logistics. Wireless is the preferred mode of communication […]
