The software may be the instrument, but at NIWeek, the hardware is the entertainer. It’s 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 baseball’s steroid crackdown.
Another colorful demo showed NI’s 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 NI’s Graphical Design System concept to create a Human and Object Transport Vehicle that’s 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 vehicle’s operation required only three days.
Software reuse helped students develop the HOT-V during a single semester.
Halloween isn’t just a time for creative costumes. Thanks to the element14 online design community, the holiday this year also brings us a number of creative electronic device design ideas aimed at making your Halloween party a unique experience.
On April 15, 2010, President Barack Obama gave a major speech at the Kennedy Space Center in Florida, announcing that the US would send astronauts to Mars by the mid-2030s. But in order to do so, NASA would first need to ramp up its capabilities through missions directed toward "a series of increasingly demanding targets," i.e. asteroids.
