Impressive engineering feats: the internet of things 
by John Eigelaar, Keystone Electronic Solutions   
 
The internet of things (IoT) has shifted gradually into the mainstream. The term describes a host of devices connected to the internet, and a blend of waveforms, fixed-line infrastructures and networks that deliver value to the organisation... (more)
In conversation with Eric Leger
by Hans van de Groenendaal, EngineerIT   
 
"There are two rationales to going green", says Eric Leger, country president for Schneider SA. "One is the financial benefit you want to extract out of going green and the second one is a corporate strategy around responsibility for the environment.  You want to build a brand that is ecologically sensitive and more green."...

Q&A - Air conditioning: challenges and solutions

by Michael McKechnie, Digital Air Solutions, Samsung SA
 
There are several types of commercial applications for cooling and heating, namely: chilled water and direct expansion. Chilled water air-conditioners are used for extensive developments like shopping centres, hotels, office blocks and hospitals... (more)
Virtual panel discussion: Lightning safety & risk management in hazardous locations  
by Hans van de Groenendaal, EngineerIT

In many locations, for instance in mining, the management of lightning risks is a formidable task. While standards do exist, not everyone in the industry fully agrees with all the recommended mitigations. We asked industry experts to share their views... (more
Wireless communications in the local government sector
Information from Emcom Wireless  
  

Digital radio communications in the African local government space can open up the world, but there are many challenges to overcome. Head of business development at Emcom Wireless, Tony Sipho Sibanda, sees the obstacles and has plotted a way to overcome them... (more)

UJ's Ilanga II solar race car launched
Information from the University of Johannesburg

The University of Johannesburg's Solar Team launched its Ilanga II solar race car on 5 August in anticipation of the biennial Sasol Solar Challenge. The eight-day challenge (27 September to 4 October 2014), starts in Johannesburg, passes through Port Elizabeth and finishes in Cape Town... (more)
The Minerals Automation Standard - a decisive step 
by Hans-J�rgen Seger, Siemens, Germany 
 
The Minerals Automation Standard is an innovative automation concept for mining that improves productivity, plant availability and efficiency. Years of experience and engineering know-how gained in projects in the cement and mining industries are at the heart of the concept... (more
Operations monitoring for plant performance, reliability and safety
A White Paper review by Hans van de Groenendaal, EngineerIT

The paper describes the implementation of an effective operations monitoring solution for process industry facilities. New software tools are available for systematically monitoring plant performance data and analysing deviations... (more)
by R Lockhart, Dataq Instruments
   
Isolating power sources and sensor signals is the most effective method for eliminating undesirable ground loop currents and induced electrical noise. When you move a data acquisition system from the controlled environment of the laboratory to validation testing or the manufacturing floor, some problems may arise... (more) 
Making conducted and radiated emissions measurements
Hans van de Groenendaal,  EngineerIT, reviews an application paper
    
An application note "Making conducted and radiated emissions measuremenrs" by Keysight Technologies looks at the pre-compliance measurement process and also discusses the US FCC requirements, emission testing and problem solving and troubleshooting... (more)
Designing for EMC: power options for LED luminaires
by Arnoldas Bagdonas, Future Electronics (Lithuania)
               


Compromises and work-arounds undertaken in an effort to meet the requirements of electro-magnetic compatibility (EMC) have had the potential in the past to markedly impair the reliability and efficiency, and increase the total production cost, of the power circuit in an LED luminaire...
Long range wireless technology enables the internet of things
by Hardy Schmidbauer, Semtech Corporation
  
New technology enables 10 x greater range than competing systems and the capacity to connect tens of thousands of nodes to a single gateway in a star architecture while maintain low power for multi-year battery operation.  This will enable the next wave of applications for internet of things (IoT)... (more)
by  Jonas Hansryd, Jonas Edstam, Bengt-Erik Olsson and Christina Larsson, Ericsson, Sweden 
 
The evolution to denser radio-access networks with small cells in cluttered urban environments has introduced new challenges for microwave backhaul. A direct line of sight does not always exist between nodes, and this creates a need for near- and non-line-of-sight microwave backhaul... (more
Information from Telit Wireless Solutions
  
We consider the internet of things (IoT) to be a concept that is based on machine-to-machine (M2M) technology. A "thing" is any smart device that can acquire data and transmit it to a facility that processes it into actionable, real-time information... (more)
by Hans van de Groenendaal, EngineerIT
  
It is true that in telecoms, fibre-based connectivity dominates in both demand and in the eye of the media with promises of low-cost business solutions and even the possibility of fibre to home solutions... (more)
