System Design

Many electronics engineers create board level products, but their boards are integrated into systems at some point. And systems need things like enclosures, power supplies and environmental management.

New Electronics recognises the importance of system design and its impact on the final product. In this section, New Electronics reviews the latest developments in system design and brings visitors to the website information on how these developments are being applied.

Security risks in the connected world

To say the Internet of Things (IoT) is here to stay may be the understatement of the decade. We are all knee-deep in the IoT and there is no turning back – gone are the days of thinking connecting refrigerators, security systems and vending machines to the Internet is in a land far, far away.

What is viable and what is not with 3D printed enclosures

Unless you've been under a rock for the last 10 years, you will have heard about 3D printing. But many engineers are still wondering how they can use it for anything other than prototyping. However, 3D printing can provide a cost effective way to construct custom enclosures and this article will explain how, when and why you should consider using 3D printing for your product.

Critical steps in getting products to market

It is said that, within the electronics industry, only one in seven product concepts is a commercial success and just 25% of product designs prove to be a winner. This is also applicable across the UK and in all sectors. So what is going wrong and why do so many fall by the wayside?

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.

Security challenges in the e-enabled aircraft

The e-enabled aircraft can provide many benefits to operators in terms of operational efficiency, passenger comfort and MRO (maintenance, repair, and overhaul). Systems on these aircraft transmit their data via satellite or ground-based communications networks to analytics services, which provide airline operators with excellent situational awareness data, leading to many value-added services. However, to benefit from this real-time Internet of Things (IoT) data, there are significant data bandwidth and security challenges to be addressed once systems are connected to a network. Systems security is of particular importance as the risks associated with allowing passengers to hack or accidentally infiltrate insecure data and systems, including associated legal issues such as breaches of data privacy, must be considered throughout the whole lifecycle of the communications network. In addition, the scope, threats, risk assessment, architecture and testing must be assessed and mitigated for every internal and external interaction undertaken by the network.

Why security is critical to the success of IoT

The Internet of Things (IoT) has exploded on to both the consumer and business markets in the last few years and is starting to have a major impact in almost every industry. From construction and manufacturing to retail and healthcare. Like it or not, IoT is here to stay.

Squeezing the performance out of ATCA through virtualisation

It is more than 10 years since the release of PICMG 3.0, the standard which defined the Advanced Telecom Computing Architecture (ATCA). Deployed in many parts of the ‘network’, ATCA is now beginning to be adopted in markets such as military and aerospace, where highly reliable computing is a hard necessity.

Understanding the need for protection from lightning induced surges

Without question, the feat of landing a man on the Moon and returning him safely to Earth, has been one the greatest engineering accomplishments in history. The complexities of escaping gravity, entering orbit, and then travelling on to Earth’s ethereal rock companion still boggle the mind nearly fifty years later. Along with thrust, propulsion, astrophysics, and zero gravity considerations, perhaps the most critical element to be considered in the success of the lunar missions was circuit protection.

When it comes to securing the future of authentication finding a solution that is both simple and strong is crucial

The biggest challenge historically in the high-stakes, cat-and-mouse game between hackers and security/authentication solutions is that stronger authentication solutions tend to create troublesome and annoying user experiences. And any solution that’s not stronger than the previous ones is, almost by definition, not up to the task of stopping attacks. Finding a solution that’s both simple and strong has been elusive.

Companies should take a more holistic approach to product innovation

A desirable product that answers real needs and is intuitive to use is likely to generate more revenue for your business. That may seem obvious, but many companies continue to be driven by technology, rather than taking a more holistic approach to product innovation. These businesses typically end up adding more clever gadgets, apps or functionality, rather than focusing on the needs of their potential customers.

Minimising costs for wire-to-board connections

Wire-to-board connections incur high costs when handling large quantities in mass markets. Using the right connection technology, however, can cut costs significantly and it is often worth considering using tried-and-tested technologies that enable cables and circuit boards to be connected at little cost.

The demands placed upon frequency products manufacturers have never been greater

A critical parameter for electronic circuits in many applications is low jitter performance, due to its influence on data transfer. Whilst all the components in the overall circuit contribute to the jitter, the timing component has the biggest single impact. Quartz-based frequency products have been used for decades as they offer a highly stable frequency over a wide operating temperature range and, despite growing competition from silicon and MEMS-based products, they continue to provide excellent jitter performance.
