People may imagine the battery as being an energy storage device that is similar to a fuel tank dispensing liquid fuel. For simplicity reasons, a battery can be seen as such; however, measuring stored energy from an electrochemical device is far more complex. The battery fuel gauge is generally poorly understood in the medical field, and this article describes the challenges of measuring energy in a battery.

Operational amplifiers provide fundamental building blocks that can be used for the buffering, amplification and/or filtering of signals. In addition, these measurements may be required under harsh conditions, such as extreme temperatures, centrifugal forces and electrically noisy environments. System designers must be diligent in designing the appropriate signal conditioning to deal with these environmental issues, and their operational amplifier’s speed should not be overlooked.

Although force measurement has become commonplace in most manufacturing environments, many of us may still appreciate being refreshed on its rudiments from time to time. Many who have attempted to educate themselves on this topic will tell you that the reading material can be a bit unpalatable. Because of this, we are pleased to offer an overview to force measurement

The intersection of nanopositioning and microscopy is expanding and deepening rapidly. The evolutions of disciplines as diverse as single-molecule biophysics, super-resolution microscopy and automated microassay scanning share several common themes which combine to increase the prevalence of piezo-based positioning systems added-to or integrated into microscopic setups. Recently developed mechanisms of significant relevance to microscopic applications present substantial new opportunities for advancement.

This article discusses the impact of increased signaling traffic fueled by growing mobile broadband and machine-to-machine (M2M) connectivity on networks, systems and network processors. While data offload strategies have received considerable attention in industry, the impact of signaling overload and mitigation strategies have not been widely addressed. A good understanding of the reasons for signaling traffic increases, its impact at the network level, system level and network processor level is needed to clear misnomers prevailing in the industry.

As applications engineers supporting ADI’s compact, low-cost, gravity-sensitive iMEMs accelerometers, we get to hear lots of creative ideas about how to employ accelerometers in useful ways; but sometimes the suggestions violate physical laws! We’ve rated some of these ideas on an informal scale, from “real” to “dream land”:
