Mobile infrastructure must catch up with user needs and demands. Ubiquitous mobile computing is all around us. Some time in the next six months, the number of smartphones on earth will pass the number of PCs. As the power and capability of many mobile devices increases, the increased demand on networks. We watch more videos, →
Here is my collection of trends and predictions for year 2014: It seems that PC market is not recovering in 2014. IDC is forecasting that the technology channel will buy in around 34 million fewer PCs this year than last. It seem that things aren’t going to improve any time soon (down, down, down until →
Here is a tear-down of one automation product. It is a relay base made by Phoenix Contact. As you can see is is a pretty normal looking relay product you see on automation systems. It mounts to DIN rail. As you can see in the picture the whole product is designed for 48V DC operation. →
Knowing the electrical characteristics of direct current and its differences in comparison with alternating current is fundamental to understand how to employ direct current. Direct current presents different problems than alternating current with a regard to the phenomena associated to the interruption of high value currents since the arc extinction results to be particularly difficult. →
The rise of direct current using devices and direct current generation have some rethinking the use of alternating current in the grid. Let’s start from history of electric power transmission: In the late 19th century both alternating current (AC) and direct current (DC) were both used to power devices like motors and light bulbs. Over →
My article Signal reference grids in the data center shows that different types of data communication interfaces are classified into susceptibility classes: Data communication interface classification Susceptibility class: Low immunity Interfaces in class: Parallel ports, RS-232 ports, Proprietary back-plane, Video cables Characteristics: Copper cabling with ground referenced signals. Any shift in ground voltage between the →
Electronics industry hopefully starts to glow after not so good year 2012. It’s safe to say that 2012 has been a wild ride for all of us. The global semiconductor industry has demonstrated impressive resilience in year 2012, despite operating in a challenging global macroeconomic environment. Many have already ratcheted back their expectations for 2013. →
I wrote in the beginning of the year 2012 a blog article Telecom trends for 2012 that tried to predict trends for year 2012. Now when year 2013 has started here is my aftermath how well my article predicted last year. So here are my comments on how well the predictions went. I use symbol →
This is aftermath how well the predictions in my Computer technologies for 2012 went. The following predictions were right: ARM processor becomes more and more popular during year 2012. The rivalry between ARM and Intel in this arena is predictably intense Windows 8 Release Expected in 2012 article says that Windows 8 will be with →
Protecting your data center against power failure is crucial to providing maximum availability. Power loss or poor power quality is a major contributor to data center server down time. This task takes more than simply having UPS and a backup power source, such as a generator. Dual Power Paths: A Crucial Element in a High-Availability →
