The software may be the instrument, but at NIWeek, the hardware is the entertainer. Itís the hardware demos that help attract thousands of engineers to enjoy the 100 degree Texas heat. Software demos spark the mind, but the image of senior vice president of R&D Tim Dehne swinging a bat or test driving a virtual car while wearing a helmet prompt greater response.
Dehne demonstrated the performance of CompactDAQ by hitting a baseball. Using a bat equipped with an accelerometer, temperature and strain gauge sensors, he showed the 3 Msamples per second speed of the modular hardware without causing concern that he will be tested under baseballís steroid crackdown.
Another colorful demo showed NIís hardware in the loop testing capability. A compactRio-based antilock braking system was tied to a vehicle/road simulator. The vehicle skidded out during a turn made without the aid of the ABS hardware, courtesy of invisible black ice that was built into the program. When Dehne drove across the icy surface with the ABS unit enabled, the vehicle remained manageable until it stopped.
The hardware demos also included outsiders. Two recent grads from Rensselaer Polytechnic Institute explained how they used NIís Graphical Design System concept to create a Human and Object Transport Vehicle thatís akin to the Segway People Mover.
The two created virtual sensors to test out the performance of the inclinometer and MEMS gyroscope that help keep the HOT-V upright as it travels. When they progressed to building hardware, they used the same software to run it through its paces. Reusing software let them focus on the higher level aspects of design, so finalizing the vehicleís operation required only three days.
Software reuse helped students develop the HOT-V during a single semester.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
