When you’re driving down the highway, the last thing you want to hear is unexpected engine noises. These noises, including buzzes, squeaks, and rattles (BSRs), make drivers nervous. Before a car ever hits the road, auto manufacturers perform rigorous tests to remove annoying BSRs.

Following instructions is not something that comes naturally to me. From my first LEGO ® model to a build-your-own-crystal-radio kit and now to IKEA flat-pack furniture, I like to ...
The official technical resource for integrating with the LabVIEW development environment and creating LabVIEW toolkits.
The middle schoolers on St. Gabriel's FIRST LEGO League team in Austin can't drive a car, but they can program a robot. They're living proof that the shift to project-based learning in science, technology, engineering, and math (STEM) education has been wildly effective.
Student teams spent six months designing and building robots that can navigate an obstacle course while identifying and retrieving objects—all without human intervention.
What if you could make a paper sketch into a digital prototype using computer vision? It's already happening: http://bit.ly/19iHxQ9


Vision Used to Design New Prototyping Tool
On this episode of Kickstarter of the Week, AppSeed has turned to Kickstarter to help grow their idea of turning paper sketches into prototypes.

Most of us know that Muhammad Ali and Michael J. Fox have Parkinson’s disease, which leads to shaking and difficulty with movement. Each year, more than 50,000 Americans are diagnosed with this neurological disorder. What you might not know is that detecting Parkinson’s is very complex, especially in the early stages of the disease.


Norconnect, Inc. set out to build a system that could algorithmically determine if subjects have Parkinson’s disease. Using NI LabVIEW and a USB-6008 data acquisition device, they built a system that detects Parkinson’s based on electromyogram (EMG) signals from hand muscles during handwriting.

The system works with gel surface EMG electrodes. These electrodes are placed in predetermined locations on the hands, and gloves hold the electrodes in place. Subjects then write on a tablet for a predetermined amount of time, during which the USB DAQ devices collects data and LabVIEW analyzes the data.


The system’s analytical program was built in LabVIEW and evaluates muscle activity during the controlled handwriting movements. LabVIEW’s intuitive graphical programming features enabled the team to develop a GUI for data collection within minutes. This statistical software is the defining differentiator between Norconnect’s system and others on the market.


Today, the system is used in medical centers and university athletic departments, and the Norconnect team presented their results at an international conference in Florence, Italy.
