Trusting the battery in critical situations
A battery is a corrosive device that begins to fade the moment it comes off the assembly line. The stubborn and unpredictable behaviour of a battery has left many users in awkward situations.
[ + ]Data bus concepts and considerations
The digital data bus MIL-STD-1553B was designed in the early 1970s to replace analog point-to-point wire bundles between electronic instruments. The latest version of the serial local area network (LAN) for military avionics known as MIL-STD-1553B was issued in 1978. Since then, various notices have been published to update the standard and after 30 years the data bus continues to be the most popular militarised network.
[ + ]Water could hold answer to graphene nanoelectronics
Researchers at Rensselaer Polytechnic Institute in New York have developed a method for using water to tune the band gap of the nanomaterial graphene, opening the door to new graphene-based transistors and nanoelectronics.
[ + ]Standby comfortable but energy inefficient
The former ‘green’ theme of energy efficiency has become a household issue in an energy-conscious society. The old filament bulb disappears step by step, and washing machines and dishwashers have become unsaleable without energy-saving programs. But most industrialised societies waste energy on a massive scale by indulging in comfortable ‘standby mode’ in domestic electronics.
[ + ]Fundamentals of FBG optical sensing
Electrical sensors have, for decades, been the standard mechanism for measuring physical and mechanical phenomena. Despite their ubiquity, these sensors have inherent limitations such as transmission loss and susceptibility to electromagnetic interference (noise) that make their usage challenging or impractical in many applications.
[ + ]Wireless measurement and data acquisition
The embedded developer b-plus was looking to migrate its XScale-based visualisation client, which is designed to be the mobile HMI for Zigbee measured data, to an Atom-based platform, to benefit from enhanced graphics and processing performance, easier long-term scalability in performance and openness in software development. One major question needed to be answered: what is the most efficient hardware platform for this application?
[ + ]Multichannel scopes enable MIMO RF testing
Multiple-input multiple-output offers the potential to increase data rates for a single user by using two or four streams of data transmitted with multiple antennas.
[ + ]The evolution in medical equipment
Cables are hidden inside hinges, shells and behind displays to save space, weight and money in manufacturing electronic equipment.
[ + ]New tricks for old dogs
We’re all familiar with the old ‘break-fix’ model of service - it’s been the way of life for many years. It works well; it generates revenue and keeps you in business alongside hardware sales. The problem is that it’s a short-term solution for a long-term user.
[ + ]Temperature control and hand devices
Quality managers and line supervisors are routinely tasked with the responsibility of ensuring that the hand soldering process is under control. The method most commonly used is to measure the idle tip temperature of the soldering station and to use this reading as a benchmark of system compliance.
[ + ]Emerging trends of HMI solutions
What are the latest trends in human machine interface (HMI)? And what should you look for, or be aware of, when you browse the market in search of new HMI solutions? The purpose of this article is to outline and describe some of the most recent key trends in software-driven industrial HMI solutions.
[ + ]LDMOS takes on the power supply
RF LDMOS (RF laterally diffused MOS), now referred to as LDMOS, is the dominant device technology used in high-power wireless infrastructure power amplifier applications for frequencies ranging from less than 900 MHz to 3.8 GHz.
