Achieve High Resolution with Robust Magnetic Motion Sensors

July 21, 2010 9:39 am | by Marcel Urban, austriamicrosystems | Comments

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.

Calibration Improves Accuracy and Stability of MEMS Gyroscopes

July 21, 2010 6:59 am | by Harvey Weinberg, leader of the Applications Engineering group for inertial products, Analog Devices, Inc. | Comments

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.

Regulations and responsibility

July 20, 2010 7:54 am | by Alix Paultre, Editorial Director, ECN | Comments

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.

Blizzard avoids PR nightmare, comparisons to China

July 13, 2010 11:46 am | by Jason Lomberg, Technical Editor | Comments

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.

Debug Code for ARM Cortex-M3 MCUs

July 13, 2010 4:59 am | by Jon Titus, Senior Technical Editor | Comments

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.
