Resolve signal integrity issues in cloud computing platforms

May 29, 2013 4:10 pm | by Bill Weir, Pericom, www.pericom.com | Comments

While the cloud promises to reduce enterprise network infrastructure and operating costs, the remote execution of applications makes factors such as latency, performance, and reliability critical considerations in the design and deployment of cloud computing platforms. A key factor determining server performance, cloud or not, is maintaining a bit error rate (BER) on the order of 1.E-12 for the overall system.

Companies can’t help the government help itself to your private electronic communications – for now

May 28, 2013 2:08 pm | by Chris Warner, Executive Editor | Comments

If nothing else, those television commercials for Microsoft’s privacy campaign really make me stand back and wonder. Usually I ask myself why the company suddenly embraces user privacy. Do they really think that Bing is going to make a measureable dent in Google’s search dominance, or do they have some kind internal or external data that suggests Americans are at least little concerned about online privacy?

Evolution of light sensor integration

May 21, 2013 10:59 am | by Darrell Benke, Sr. Marketing Manager, Opto Sensors and Lighting, ams AG | Comments

Light sensing technology, in the form of photodiodes and phototransistors, was invented around the 1950s. Since the inception of the first optosensors, the devices have gradually found their place in commercial and industrial applications, but their adoption was limited due to the size, cost and overall performance.

Certifying industrial systems using IEC 61508

May 21, 2013 10:52 am | by Shrikant Satyanarayan, LDRA, Inc., www.ldra.com | Ldra Technology, Inc | Comments

The IEC 61508 standard is a risk-based approach for determining the SIL (Safety Integrity Level) of safety instrumented functions. If computer system technology is to be effectively and safely exploited, it is essential that the available guidance on these safety-related aspects is adequate to make correct decisions.

Designing for heat

May 21, 2013 9:53 am | by M. Simon, Technical Contributor | Comments

I want to start off with a look at the four methods of cooling: conduction, convection, radiation, and pumping. What? They don't teach the four methods of cooling in physics class? Only the first three? The fourth method is a combination of the first three with the addition of pumps.

Wireless networks balance military’s defense-in-depth, custom requirements

May 20, 2013 4:44 pm | by Chris Warner, Executive Editor | Ultra Electronics Ems Development Corp. | Comments

Wireless and wired technologies have advanced to the point where automated control systems are routinely networked together. Information can be shared and tasks performed across long distances, via the Internet, linking systems in large industrial spaces, or across remote or rugged areas. Networked control systems (NCS) offer many benefits such as far greater efficiency than manual controls....

Hybrid capacitor characteristics, performance, and applications

May 16, 2013 2:15 pm | by David A. Evans, Evans Capacitor Company, www.evanscap.com | Comments

An electrolytic capacitor has two electrodes, one with a dielectric, that relies on electrostatic charge storage. A battery has electrodes that store energy faradaically in electrochemical reactions involving the electrodes and electrolyte. A hybrid capacitor is the combination of two electrodes, one that stores charge electrostatically, and the other storing charge faradaically.

Smart electronics reduce energy consumption and improve performance of piezoelectric ultrasonic motors

May 16, 2013 2:10 pm | by David Henderson, co-CEO, New Scale Technologies, Inc., www.newscaletech.com | Comments

Piezoelectric ultrasonic motors (piezo motors) are a distinct class of rotary and linear actuators requiring unique driving circuits to achieve practical, reliable, precise and efficient operation. A piezo motor uses the ultrasonic vibrations (greater than 20 kHz) of a “stator” structure that is frictionally coupled to a moving slide or rotating shaft. Piezo motors with operating frequencies from 40 to 700 kHz are commercially available.
