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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diegoís Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a personís sweat.
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.
