NI Week, the huge exposition that NI
puts on every year, is around the corner. We hope to see as many of
you there as we possibly can, whether at the Convention Center or afterwards
on 6th Street. Even though Independence Day is past,
this collection of slow motion fireworks is cool: http://www.popsci.com/science/article/2011-06/celebrating-fourth-july-ultra-slow-motion. I especially liked the extended version
of the mayonnaise jar (the “Mayo Bomb”) linked farther down the
page. Thanks for reading!

 Part 4: RIO Process Communications Reference Designs in an Embedded LVRT Application
|
|
We wrap up the series on embedded applications with a closer look at some Reference Designs for inter-process communications. The app architecture for the RIO platform sketched out last month has three components: FPGA, RT, and Client PC. Data and state is shared between these parts by using FIFOs for lower level code and TCP between the RT layer and the PC. The TCP-based communications should be based on some standardized code, called Reference Designs. Viewpoint developed such code years ago for our project work. Now, NI has some tools on their website as free downloads that are very similar to ours. You should use them too. Read on... |

50 Years of In-flight Movies |
|
Fifty years ago the first in-flight movie, By Love Possessed, was shown on a Trans World Airline flight from New York to Los Angeles. The screening was available only in the first-class cabin. This air travel entertainment was developed by David Flexer, a film buff who owned a small chain of movie houses. Flexer was on a transcontinental flight in 1956 when he realized that “air travel is the most advanced form of transportation and the most boring”. Flexer had several technical problems to overcome; he needed to find a way to put full films onto single reels and build a projector that could withstand the turbulence of flight and be light enough to mount on a plane. Finally, after three years of development and $1 million of his own money, Flexer’s company Inflight Motion Pictures developed a new design that projected large 16mm reels and weighed less than 100 pounds. Most airlines were not interested in partnering with Inflight Motion Pictures, except TWA who was looking to increase its profile. On July 16, 1961 TWA began offering films to first class passengers. The response was overwhelming and passengers began paying huge fees just to be able to catch a show in-flight. In-flight movies quickly became a staple of air travel and continue to be a popular mode of entertainment along with in-flight satellite radio, video on demand, and wireless internet. http://www.wired.com/thisdayintech/2011/07/0719twa-inflight-movies/ |
