It hasn’t just been Mt. St. Helens that has caused havoc; in fact, it might have been rather tame when compared to Iceland’s Eyjafjallajökull 2010 explosion that caused an economic hit of approximately $2.2 billion to Europe’s aviation industry, and severely affecting easyJet.

Launched by a Kickstarter program that raised its goal of $35,000 in just 11 hours, and ultimately reached $346,127, the iSketchnote digitizing iPad cover will be available commercially in July 2014 at a price of $189.


Using an array of MEMS magnetometers from STMicroelectronics, users can draw on any sheet of plain paper laid on the inside flap of the open cover to digitize their schematics in realtime, which appear on the iPad screen as they draw. Passive pens with embedded ring magnets are tracked by the magnetometers to reproduce the drawings on the iPad screen with sub-millimeter accuracy, according to ISKN.

ISKN has developed algorithms that can very precisely locate the position of the pen’s tip, from the location of the magnet in the pen body, using the three-axis magnetometers from STMicroelectronics,” said Stephen Walsh, a consultant for ISKN who also teaches electronics classes as an adjunct faculty member at North Carolina State University (NCSU).

Walsh plans to use the iSketchnote to draw electronic schematics for his classes when it becomes available next year. A special animation feature will also be useful, since it allows the sequence of a drawing to be played back, allowing him to pre-draw schematics one stage at a time, then play back the animation in class explaining each stage as it is redraw for the students.


The iSketchnote was not conceived by ISKN with engineers specifically in mind, but rather for iPad users who miss the freedom of drawing or taking notes by hand on real paper. It will come with a variety of different colored pens, which the iPad will reproduce in the matching color.


Next, the engineers at ISKN plan to expand from iPad covers into whiteboards, game boards, 3-D animations and other applications of their pen-tracking technology.

With increasing speed of computing hardware and increasing complexity of in-flight systems, space travel is becoming more and more dependent on software. A small group of professionals from JPL, APL, The Aerospace Corporation and SWRI kept finding themselves gathering after other events to discuss the software-related issues with space flight and ultimately decided to create their own event, The Flight Software Workshop.

Lineback also pointed to companies such as Facebook and Google as drivers of the current market. Large internet service providers are interested in doing customized servers and having them just assembled in Asia, and that’s also having an impact on the market as well,” he said. It’s taking away some business from HP and Dell, leaders of the traditional server market.”

That period of growth may be short-lived, however. According to the report, servers made up 13% of total computer systems revenue in 2013 and are expected to reach record high sales in the next three years. But then another economic downturn is expected to halt that rise in 2017. That’s the year when we expect to see an economic down year. Most of the markets are going to go through that,” Lineback said. We just see ’16 being the peak year in the current cycle, but it’s due to the overall economy and is not specific to servers.”

Elsewhere in its report, IC Insights predicts that microserver sales will rise by 139% in 2014 to $580 million from an estimated $243 million in 2013. The report also projects microserver sales to increase by nearly 72% between 2012 and 2017, coming to $1.2 billion by 2017. These increases are taking place in what Lineback calls an emerging market niche.” He adds that the numbers show growth that’s rather strong as internet service providers and those running the networks are looking for ways to deal with the huge volume of traffic going over the internet. Most of the work is relatively mundane or low, lightweight computing,” he said. It’s somewhat akin to blade servers where you can pack a lot more onto a single core. There’s an effort right now to apply microservers to a wider range of computing.”

Lineback made reference to rumors that Google is looking to make its own processors as an indication of the new trend that internet service providers are coming into the server business in full force. It fits into what Apple did with the iPhone and the iPad. It makes sense for what Google is trying to do. They’re a big enough company. They could deliver cloud computing to chromebook, their platform. They’d be interested in maybe going so far as doing their own processors. They could easily do what Apple did and find their own foundry. It could be Samsung. Apple and Samsung already work together and Apple and Google see each other as competitors. Google has enough places to go to get server processors. Google could go to TSMC or Globalfoundries, wherever.”
