Defence

Electronics has always been an important element of the defence sector, enabling communications, intelligence gathering and navigation. But the market differs from many others in its reliability requirements and the need to support products for extended periods. This means companies involved in the sector, as well as those looking to enter the defence supply chain, need to keep up to date.

New Electronics covers developments in the defence sector, bringing technology updates and opinion from the market.

How innovation in rechargeable lithium cells is helping designers overcome power limitations in miniature devices

Designers of portable electronics products are familiar with the related challenges of space and weight reduction. It seems there is no limit to consumers’ desire for their devices to be thinner, lighter and sleeker. And in a product such as an earbud (or in-ear speaker), the form factor is absolutely constrained – in this case, by the size of the human ear.

M2.COM Internet of Things sensor platform unveiled

According to its creators – Advantech, ARM, Bosch, Texas Instruments and Sensirion – M2.COM is an evolutionary module technology designed specifically for IoT sensors and devices. With networking, computing and data collection features on one module, M2.COM is intended to help transform obsolete applications into IoT generation solutions. The partners note the modular design is said to make the concept flexible enough to support different applications and to meet the changing demands of the IoT world.

Part art, part science

The development of backplanes for high performance designs is certainly challenging. The key appears to be ‘don’t do it yourself’, especially if you are looking at customised designs.

A layered approach to enhancing security for safety-critical software

Today’s safety-critical embedded environments are becoming more connected to the outside world. The ongoing growth of the Internet and IoT solutions will further drive connectivity requirements for safety-critical systems for the foreseeable future. Aerospace, defence, automotive, medical and industrial control are just some of the vertical markets that will expand as the ability to interconnect and remotely work with devices grows.

Sensors for a smart environment

Sensors have evolved from simple measuring tools to smart appliances that are connected through the internet to the cloud and to each other. At the recent ISSCC-conference, researchers from imec and Holst Centre presented a number of developments which may pave the way to a world where sensors assist us to drive more safely, live more healthily and make the planet more sustainable.

High throughput, low power requirement

For cloud and IoT applications, there is a rising need for flexible GbE firewalls in corporate network infrastructures. With integrated Open Source and x86-based AMD Embedded G-Series SoCs, Deciso’s OPNsense firewall appliance offers double the flexibility. It enables high throughput with low power consumption making it suitable for both enterprise and IoT appliances.

3U VPX module wins PCB design competition

Form factors, new technology, thermal management and the need for more voltage rails are some of the challenges which face those designing board level products. While software is helping to address the challenges, the success or otherwise of the design comes down to good, old fashioned team work and skill.

ATEX and how this applies to power supplies

The acronym ATEX, derived from the French phrase "ATmosphere EXplosible”, was initially introduced in the European Union to facilitate the free movement of goods and services of equipment used in hazardous environments.The resulting ATEX Directive removed the need to test and document a product for each EU country by harmonising the way different hazardous explosive environments are classified across all industries.

How designers can take advantage of the latest product developments in intelligent power modules

The move to replace simple fixed speed motor drives with more sophisticated variable speed drives (VSDs) is gathering pace, driven by regulations such as the European Commission’s ErP (Energy related Products) Directive. As a result, manufacturers of electric motors are equipping their products with the ability to match their speed and power output to the load, providing for a reduction in average power consumption.

CES 2016 suggests technology business is alive and well

Looking for a drone? Angling for an HDR enabled TV or a virtual reality headset? Want the latest in smart home devices or to find out more about recent developments in autonomous vehicles, then the Consumer Electronics Show (CES), held in Las Vegas last month, wouldn’t have disappointed.

What is the usable power in a DC/DC converter?

The term ‘high usable power’ is widely used by the manufacturers of DC/DC converters to describe their product’s performance. Many engineers though tend to focus on the datasheet’s rated current and assume that, by selecting a more expensive, higher power converter, it will give them more derating and improved reliability.
