Video: Warping a telescope lens to match atmospheric distortion
NIWeek demo simulates atmospheric distortion collecting 500 high-resolution frames per second through machine vision, into an FPGA into four rack-mounted controllers that instruct more than 1,000 actuators how to change a 42 meter diameter telescope lens in less than 2 milliseconds.
Warping a telescope lens to match atmospheric distortion: A new European ground-based telescope uses NI-based parallel computing connected via a high-bandwidth backplane (via PXI System Alliance) to quickly adapt the lens to atmospheric distortions. The demo simulates atmospheric distortion with a flame, collecting 500 high-resolution frames per second through machine vision, into an FPGA into four rack-mounted controllers that instruct more than 1,000 actuators how to change the 42 meter diameter telescope lens, all in less than 2 milliseconds, explained Patrick Webb, NI PXI Systems, product marketing manager. The computational equivalent of 64 interconnected computer nodes could control and balance 320,000 inverted pendulums. Just 5 years ago, balancing one pendulum was an impressive demo, Webb said.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
