Testing Today’s Most Complex Consumer Device: The Ubiquitous Smartphone

We’ve come a long way since Alexander Graham Bell’s famous words, “Mr. Watson, come here” were spoken and the telephone was born. The simplicity of use of today’s smartphones, tablets, and similar smart devices belies the underlying complexity of creating a device that can connect virtually anywhere, at anytime. While there are other consumer electronic devices that have increased in complexity and capability, the majority of the smartphone’s complex structure is completely hidden from the user. At the same time, “when can I upgrade” is a common mantra of users. The fast-paced and high-volume production required in this environment continues to add complexity to mobile device testing, and has necessitated the rethinking of traditional test methods.

Camera Systems Rapidly Scan Large Structures

Thermography designed to protect aircraft from effects of aging finds use in power stations, manufacturing plants, and ships. Aging aircraft are an increasing concern. Commercial and government vehicles are being flown past their originally intended service life in order to save money. The answer, however, isn’t merely to build more aircraft. NASA’s Aircraft Aging and Durability (AAD) Project is taking a proactive approach to extending the life of aircraft even before age is a concern. The project targets young aircraft, and develops technologies and materials to mitigate the effects of aging as early — and for as long — as possible.

Speed2Design: A Chance of a Lifetime

I recently had the chance to spend a day at NASA’s Johnson Space Center in Houston with the ten winners of the Speed2Design contest sponsored by Littelfuse, a Chicago-based circuit protection company. The prize was a behind-the-scenes tour of the center, including technical conversations with the engineers working on robotics and rovers, astronaut training, and International Space Station (ISS) research. Having been to NASA facilities multiple times, I had a “been there, done that” attitude at first, but was quickly as amazed and awed as the winners by the technologies and facilities at NASA Johnson.

Industry Roundtable: Analysis & Simulation Software 2013

In our annual poll of executives at leading analysis and simulation software vendors, we found that high-performance computing is changing the way software is written and sold, and that in a competitive economic market, simulation is not just an advantage, but a necessity. In today’s environment of doing more with less, designers and engineers are constantly pressured to increase productivity, especially in small- and medium-sized businesses where a few people perform the tasks of many. As a result, simulation becomes not only a productivity tool, but also a competitive advantage, and as some of our executives put it, a competitive necessity.

Elemental Scanning Devices Authenticate Works of Art

A scanner used to analyze spacecraft components can help identify a real Van Gogh. Are the shoes you’re wearing really made of leather? Is the table nearby made of wood? How can you be sure? These questions may seem trivial in everyday life, but knowing the precise chemical makeup of spacecraft components is a crucial part of quality control and can help ensure a successful mission. And learning that the paint on a canvas was produced using modern materials could be what prevents a museum from spending $10 million on a forgery.

3D Visualization Technologies: Seeing a World of Opportunity

Industries as diverse as architecture, engineering, construction, advertising, and medical have all incorporated an array of 3D visualization technologies into their design, development, and production processes. A rapidly expanding library of 3D modeling tools, 3D content, and 3D printing materials have made design more cost-effective and expedited the product-to-market process. But how exactly do 3D visualization technologies work? Taking a closer look at the science behind the innovation reveals a striking convergence in which state-of-the-art research processes meet a growing understanding of visual communication.
