The 1D works great, but when we tried to load a large 2D map, we got an endless pop up error that wouldn't go away until we deleted the control from the workspace.

Two important elements in a sustainable urban infrastructure are public transportation and green structures. Not only are they important, but they also help create sustainable living conditions for a

community. That’s why engineers at National University of Singapore created the first working prototype of a zero-energy bus stop (node) that was also user friendly for commuters.


Powering a zero-energy bus node that is self-sustainable requires electricity. The engineers needed to situate solar panels on the top of the bus node. To further the energy supply, they mounted the solar panels on a rotational base that causes the panels to adjust with the weather information received by a controller. Using the energy supply from the abundant sunlight created enough to power one entire bus node.


The next crucial element was creating a solar panel powered system. The engineers created a three-part system made up of sensors, actuators, and a controller. They used NI CompactRIO hardware and LabVIEW software to give the controller capabilities for obtaining up-to-date arrival times, current traffic conditions, and other navigation information for passengers right on-site.

The use of integrated NI hardware and software helped engineers create the first working prototype of a zero-energy bus node. This entire bus node is 100 percent self-sustainable in electricity consumption and Singapore now has a ready platform for energy control activities that will help create a more sustainable infrastructure in the future.

TDMS files can store large amounts of test and measurement data. However, when a channel contains an extremely large amount of files, your system can get overloaded. If you want to free up some space and keep your front panel from locking up, this example code can help divide these large channels into smaller segments and add them back together for a more efficient system. Your computer shouldn’t get stuck opening and closing a file 50,000 times just because you have 50,000 samples in one channel.

Budgets and budget cycles can sometimes interfere with making wise training investments. With training credits, you can purchase training now (when you have the budget) and schedule it later (when you need the training).


Purchasing for yourself? You don't have to know what, when, or where you will take training yet. Managers don't even have to know who will be trained yet. Spend the budget while you have it, and schedule the training later when you need it.
