Windows 8 takes an inspired new approach to its user interface. The latest OS changes the way you'll interact with your PC—and your test and measurements. If you’re worried that this change will cause complications: don’t. For the most part, software that works in Windows 7 will transition seamlessly to Windows 8.

National Instruments has done extensive testing with our application software and hardware device drivers to ensure that customers who move to the new OS will have few problems. And in 2013, National Instruments will officially support Windows 8 as an OS option for our controllers.

There are also some great features available in this OS. One we’re most excited about for NI is the upcoming Surface Pro tablet, which will run the same version of the OS as desktop PCs. It will allow customers to plug in their USB DAQ devices and run LabVIEW applications on their tablets. The Surface Pro will release in Q1 2013.


National Instruments will also have a version of the NI Data Dashboard available for Windows RT on the Surface tablet in the next few months. Data Dashboard 1.0 for Windows RT will allow engineers to create custom dashboards to monitor LabVIEW applications remotely.

NI LabVIEW is a diverse graphical system design tool, and people who use it are doing some awesome things. LabVIEW is used in almost every industry, and when it comes to the medical industry, nothing compares. Researchers using LabVIEW are making huge progress in their industries, and the latest and greatest from the medical industry is a cost-effective liver dialysis prototype for clinical trials.

"The combination of LabVIEW and CompactRIO hardware significantly contributed to the deployment success of the prototype of our innovative liver dialysis therapy. Using NI technologies helped us deliver the first system within just seven months.”  Holger Chab, Hepa Wash GmbH

 

 

 

Researchers at Hepa Wash wanted to create a prototype that met performance and specification requirements set forth by the company, and achieved medical device safety under guidelines set forth by the International Electrotechnical Commission. Researchers used the LabVIEW FPGA and LabVIEW Real-Time modules with NI CompactRIO hardware to control the liver dialysis therapy prototype, as well as NI Requirements Gateway software to automatically create traceability documentation between requirements, tests, and design. By using all of these tools Hepa Wash achieved authorization for clinical studies within seven months.

Red Bull is sponsoring the Red Bull Stratos project that will take world famous base-jumper and pilot, Felix Baumgartner, 120,000 feet above earth to make the longest stratospheric free-fall jump known to man. The mission is to gather data while setting history, and for Felix to be the first human to break the speed of sound with his body.

To keep Felix safe, and make sure that he is prepared, the Red Bull Stratos team uses LabVIEW to control and monitor everything from altitude, air pressure, temperature and more. In a preliminary training scenario recorded and published in the video below, screenshots of LabVIEW are shown measuring and monitoring the capsule and air pressure around it.

 

 

 

 

 

 

This preliminary training scenario takes Felix into a pressure chamber that simulates the conditions of the jump and atmosphere. This prepares Felix and his body for the cold, vacuum like conditions of falling through the real atmosphere. When it comes to Red Bull Stratos and LabVIEW, it isn’t just about making history, it’s about protecting Felix’s life too.

In the United States diabetes is on the rise, with 25.8 million Americans known to be diagnosed in 2011. Since there is such a large diabetic population, many medical device companies are developing innovative and more efficient ways to help manage diabetes, especially for our “on-the-go” fast paced society. That’s where NI LabVIEW comes in.

 

Advanced Instruments Technologies Inc.—a National Instruments Alliance Partner— and Test Systems Pro Inc. used LabVIEW software, the NI Spectral Measurements Toolkit, NI TestStand, and NI PXI RF hardware during RF and production tests of a subcomponent for an FDA Class II medical glucose meter and insulin delivery system. This system uses RF technology to wirelessly communicate the blood glucose readings of the diabetic to an insulin delivery actuator that pumps insulin accordingly. LabVIEW was used to create fast, repeatable tests and streaming RF record and playback, which made integration quick and easy.

 

With this technology, we are one step closer to finding a cure for diabetes. The ability for a glucose meter to wirelessly communicate to an insulin delivery device opens the door for diabetics to have better control and fewer complications.

Today, bridge structures are tested with unique constraints. Vehicle loads and extreme conditions give researchers a better understanding of the impact these structures can withstand. However, bridges are not being designed for both of these conditions at the same time.

 

Researchers at the University of Nevada, Reno are using graphical system design to test bridge sections and the extreme conditions they may endure. To better understand the behavior of these immense structures during an earthquake and the combined load of a vehicle, researchers wanted to accurately test how the vehicles suspension system interacts with the movement of a bridge. They achieved this by building bridge sections and simulating earthquakes with large hydraulic shakers.

 

NI data acquisition hardware and the NI LabVIEW Real-Time Module helped the researchers easily program a system that could monitor critical components of their simulation such as strain, force and displacement. The ability to collect and process accurate data all with one platform made the test system a huge success. The entire system design gives researchers the capabilities to better understand the behaviors and movements of the structures we drive across every day.

According to leading global market research firm Frost & Sullivan, the PXI market is expected to cross the $1 billion mark by 2017. And in a recent report, they added how NI is paving the way with our continuously advancing PXI modular instrumentation powered by LabVIEW.

 

“The PXI market is growing, gaining share over rack-and-stack instruments, and National Instruments is the undeniable leader in PXI-based test and measurement equipment,” said Jessy Cavazos, industry manager for measurement and instrumentation at Frost & Sullivan. “This is not surprising considering the breadth and depth of its PXI product portfolio.”

Armed with NI LabVIEW software, CompactRIO, and PXI hardware, researchers at the University of Zagreb in Croatia have established the Laboratory for Renewable Energy Sources, or LARES. We all know that green is the way to be, but as the demand for clean energy grows, the need to make it efficient and readily available does as well. To meet such demands, LARES conducts research on controlling and storing wind, hydrogen, and solar energy.

 

Let’s get the nuts and bolts straight. LARES is a microgrid consisting of a custom-made wind turbine, an electrolyzer and fuel cell stack for hydrogen production, and solar panels. It was designed to investigate and develop microgrid algorithms to control specific energy sources. Designing these control algorithms can be tricky, because the amount of energy produced by renewable sources is often unpredictable. The algorithms require many control loops and real-time hardware operation on a millisecond time scale. That’s a definite need for speed. With the help of NI products, the LARES engineers laid the foundation for virtual power plant control and made green energy a more reliable power source for the future. Captain Planet would be proud.
