How to Choose a Controller for Motor Applications
For many engineers, pulling all the parts together - the controller with embedded or separate algorithms, the drivers, and the MOSFETs - is a multidisciplinary task, and one for which they dont want to "reinvent the wheel."

China Adopts Cybersecurity Law Despite Foreign Opposition
Bloomberg News: China has green-lit a sweeping and controversial law that may grant Beijing unprecedented access to foreign companies’ technology and hamstring their operations in the world’s second-largest economy.
The Cyber Security Law was passed by the Standing Committee of the National People’s Congress, China’s top legislature, and will take effect in June, government officials said Monday. Among other things, it requires internet operators to cooperate with investigations involving crime and national security, and imposes mandatory testing and certification of computer equipment. Companies must also give government investigators full access to their data if wrong-doing is suspected.
China’s grown increasingly aggressive about safeguarding its IT systems in the wake of Edward Snowden’s revelations about U.S. spying, and is intent on policing cyberspace as public discourse shifts to online forums such as Tencent Holdings Ltd.’s WeChat. The fear among foreign companies is that requirements to store data locally and employ only technology deemed “secure” means local firms gain yet another edge over foreign rivals from Microsoft Corp. to Cisco System Inc.

For Visio, PDF is the new DWG
During discussions with the Visio product team I realized that PDF is the new intermediate file format for Visio, not DWG. For example, PDFs from AutoCAD are plotted at a specific paper size and scale, perfect for Visio.
Industry 4.0-based Network Manager Ensures Solid Industrial Connectivity
Network connectivity of industrial equipment and devices is a vital element of Industry 4.0. If the connection fails, all data communication from field devices to back-end servers and cloud networks will be halted, disrupting the operation of Industry 4.0.
How Blockchain will Transform the Enterprise
With machine-to-machine communication, how does one validate "identities" and secure data at such massive scale.
Using 3D Printers in Manufacturing
The 3D printing industry is expected to change nearly every industry it touches, completely disrupting the traditional manufacturing process. As a result, the projected value of the industry is expected to explode in the near future
Hall Effect Technology Reaches a New Level
For electrical motors with variable speed drives, fine current control in varying operating temperatures improves speed and torque control and can also provide energy savings of up to 30% or more.
From OLED Encapsulation to Plagiarism Protection
When ultra-thin transparent varnishes are applied onto transparent foil tapes, defects in the coating can now be made visible immediately during the coating process. This is possible thanks to an inline detection system that uses fluorescence dyes.
Additive Manufacturing
The most popular and widespread technology is FDM (fused deposition modeling), known also as FFF (fused filament fabrication). The majority of companies apply this technology in numerous printers, both of "amateur" and of "professional" classes.
Metamaterial Mechanisms
From the Hasso Plattner Institute:
Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions.
So far, metamaterials were understood as materials—we want to think of them as machines. We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. Our metamaterial Jansen walker consists of a single block of cells—that can walk. The key element behind our metamaterial mechanisms is a specialized type of cell, the only ability of which is to shear.
In order to allow users to create metamaterial mechanisms efficiently we implemented a specialized 3D editor. It allows users to place different types of cells, including the shear cell, thereby allowing users to add mechanical functionality to their objects. To help users verify their designs during editing, our editor allows users to apply forces and simulates how the object deforms in response... (project homepage)
3D Printers in Schools
Just imagine: students are working in a classroom at their computers modeling their projects, then 3D print their models. Some time ago it would look like a fantasy, now its going to be a reality.
Factory Equipment Maintenance and Industry 4.0
The automation and collection of information thats available from machine to machine communication enables manufacturers to transition from corrective to preventive maintenance and ultimately to predictive technologies which rely on more information and data collection.
