AUGMENTED REALITY: Beyond Gaming to Real-World Solutions

Ask a stranger off the street what Virtual Reality (VR) is or how it works, and most people will have some inclination of what the technology entails; however, ask that same person about Augmented Reality (AR), and the answers are less likely to be easily gained. Maybe someone will talk about the gaming aspect of the technology, or its earliest incarnation in the failed Google Glass.

Using Formal Methods for Engineering Embedded Systems

Between 1985 and 1987, a radiation therapy device called the Therac-25 was involved in at least six incidents in which the device delivered massive overdoses of radiation. The patients involved suffered radiation burns and symptoms of radiation poisoning. Three of those patients eventually died, all because of a latent software bug. A race condition had gone undetected. It was a test case no one had thought to define.

Software Models Electromagnetics of Wireless Power Transfer

Imagine coming home and dropping your phone, laptop, and Bluetooth® headset on your kitchen table so that they all recharge simultaneously. What if you could drive your electric car into a garage, park above a mat, and know it will be charged in the morning? What if there was a new medical implant to replace the one you wear — and the new version does not include power cords or the need to replace batteries?

Improving Weapons with Simulation

As engineers design new weapons or modify existing ones, reducing time and money on development can be critical in providing soldiers with improved weapons without undue delay. A new sight may be planned for the M4 rifle, but how well does a prototype design work, and where would be the best place to mount it for the best accuracy and ease of use? Or new, nonlethal weapons may be needed, but will they perform as expected at different ranges?

Simulating Material Migration

Accurately tracking and predicting the subsurface migration of specific materials over time and over multiple phases is critical to efficient and effective strategy development and deployment in a growing number of applications. STOMP (Sub surface Transport Over Multiple Phases) is a general-purpose tool that provides multidimensional analysis of subsurface flow and reactive transport phenomena. It was originally designed to support environmental remediation of subsurfaces contaminated with volatile organic compounds and/or radioactive material.

Optimizing Fuel Filters via Simulation

Cars contain numerous filters for air, fuel, and oil. Those who develop these filters are confronted with many requirements. The products must withstand intense temperature fluctuations and vibrations, fit into a predefined installation space, and comply with increasingly stringent quality standards, all while development times get shorter.

Designing for 3D Printing

3D printing has progressed over the past decade to include multimaterial fabrication, enabling production of powerful, functional objects. While many advances have been made, it still has been difficult for non-programmers to create objects made of many materials (or mixtures of materials) without a more user-friendly interface.

A 40-Year Legacy and Excitement for the Future

As I approach retirement after 40 years as CEO of National Instruments (NI), I am reminded of the great progress and innovations the test and measurement industry has witnessed over that time. We have gone from an industry driven by vacuum tube technology in the era of General Radio, to a time where the transistor ruled with Hewlett-Packard, to today where software truly is the instrument — a transition that NI helped shepherd.

The Synergy of Engineering

At the Hannover Messe trade fair in Germany, Eplan Software & Service, with its affiliate company Cideon, introduced Syngineer, an innovative communication and information platform that integrates mechanical engineering, software engineering, and controls engineering through one mechatronic structure. Eplan, a sister company of Rittal Corporation in the Friedhelm Loh Group, offers Syngineer as a solution for simplifying synchronization across all three disciplines, accelerating design engineering and development.

Celebrate Pi Day with NASA Goddard and Discover Pi-Sat

The Innovative Technology Partnerships Office (ITPO) at NASA’s Goddard Space Flight Center (Goddard) in Greenbelt, MD, invites you to celebrate Pi Day on March 14 and discover Pi-Sat. Current technology trends indicate a shift in satellite architectures from large, single satellite missions, to small, distributed spacecraft missions. At the center of this shift is the smallSat/cubesat architecture.
