A growing number of applications require linear motion sensing, including X-Y tooling tables, pneumatic pistons, automatic sliding doors and zoom lenses. One commonly used technique involves resistive strips (potentiometers). While this approach is simple and inexpensive, it depends on mechanical contacts so it is prone to wearing out.
Gyroscopes are often used for inertial navigation or other applications where high accuracy or stability is required. To maximize performance, the gyros used in these applications are generally calibrated and externally temperature compensated. This article outlines a method for performing calibration and temperature compensation.
Is the designer responsible for the effects of the device created? Is the manufacturer? What about the salesperson or the marketing department creating the demand? Is the user ultimately responsible? Every tool and technology, no matter how mundane, has effects beyond the intended function.
Will unmanned drones ever replace manned fighter jets?
Blizzard Entertainment has narrowly avoided a public relations nightmare: an unfavorable comparison with Communist China. The game publisher recently announced plans (then shelved them) to require real names (“Real ID”) on its forums. Meanwhile, China has vowed “to reduce anonymity” on the internet.
In this month's Roundtable, we ask our guests about the impact of military RPV tech on the development of civilian systems.
ARM counts six large silicon suppliers as licensees for the Cortex-M3 processor core, which attests to its popularity. Microcontroller manufacturers license the Cortex-M3 core and its attendant debug-and-trace macrocells, called CoreSight. The CoreSight block includes many capabilities, and hardware and software engineers should know how to take advantage of them.
Today’s high-performance equipment calls for innovative components designed specifically to meet their market demands. The developments in linear-position sensors have proven to be an effective means for increasing productivity, quality assurance, and profitability in many industrial applications.
JTAG, also known as IEEE 1149.1, is one of the most successful electronic standards of all time. Invented over 20 years ago to uncover printed circuit board manufacturing, JTAG is now used in nearly 100% of printed circuit boards and has become a critical part of many integrated circuits.
There are many industries that depend on the proven design concepts that require high voltages to operate. Radar, X-ray machines, traveling wave tubes, down-hole logging, particle accelerators, aerospace ignition systems, partial discharge detection, power utilities and welding equipment are some examples.
Multi-core and embedded virtualization offer embedded device and equipment manufacturers the chance to consolidate and innovate. They can consolidate multiple individual processors into a single processor, whether single core or multi-core, and innovate by improving the capabilities of their devices beyond what was previously achievable.
With increasing pressure to lower test costs, many RF test engineers face the challenge of reducing measurement time. As you might expect, wireless LAN (WLAN) device testing is no exception. Whether you are creating an automated test system for design validation or final production test, it has become increasingly important to optimize a test system for measurement speed.
Multi-core has become a hot topic in recent years. We have now reached a point where multi-core adoption is starting to follow common use cases. The following provides a framework for understanding how multi-core can apply to your project.
As the capabilities of end products continue to multiply, many embedded system developers are forced to steer away from working with single core processors and move towards multicore processors. Only multicore processors can deliver on today’s demands of increased processing power, robust power performance and lower costs.
4G, LTE, WiMAX, IPTV, etc. – you name it and these advanced IP-based services are upon us, and more are coming. The IP communications layer for multimedia and data-centric Next Generation Networks needs tremendous performance and sophisticated improvements in order to connect billions of devices...
