What Engineers and Customers Need from a Motion Control System

In the automation industry, engineers strive every day to advance their process and products. Engineers have to select components, learn and use many tools to construct their automation systems, and support the systems in production. More importantly, to be successful and competitive, they are faced with many challenges to achieve higher throughput and ease of use within budget and time limitations.

Product of the Month: August 2015

Microchip Technology, Chandler, AZ, offers the PAC1921 high-side current/power sensor with both a digital output and a configurable analog output that can present power, current, or voltage over a single output pin. Power-related output values are also available over the 2-Wire digital bus, which is compatible with I2C™. The sensor, available in a 10-lead 3 x 3-mm VDFN package, was designed with the 2-Wire bus to maximize data and diagnostic reporting, while having the analog output to minimize data latency. The analog output can also be adjusted for use with 3V, 2V, 1.5V, or 1V microcontroller inputs. The sensor is suited for networking, power distribution, power supply, computing, and industrial automation applications that do not allow for latency when performing high-speed power management. A READ/INT pin enables host control of the measurement period, and the pin can be used to synchronize readings of multiple devices. For Free Info Visit http://info.hotims.com/55592-120

NASA and Industry Create Mid-Infrared Detector

NASA Goddard scientist Xiaoli Sun and his industry partner, DRS Technologies (Dallas, TX), have created the world’s first photon-counting detector sensitive to the mid-infrared wavelength bands — a spectral sweet spot for a number of remote-sensing applications, including the detection of greenhouse gases on Earth, Mars, and other planetary bodies as well as ice and frost on comets, asteroids, and the Moon.

A Tale of Tails

Tests were conducted recently by Boeing and NASA to answer the question: What if reducing the size of an aircraft’s tail could lead to more efficient air travel? The tests, focused on a technology called active flow control, are part of the Boeing ecoDemonstrator program. Active flow control is a technology that could result in a tail that is 17% smaller. This would reduce drag by about 0.5%, and would also reduce the tail’s weight, both of which cut an airplane’s fuel use and carbon emissions.

Editor's Choice: August 2015

NASA is developing the next generation of radiators using a composite that combines low density, high thermal conductivity, and high strength. A scalable process was developed that incorporates nanoparticles into magnesium that forms a high-strength, high-thermal-conductivity nanocomposite. Other applications for this technology are consumer electronics, automobile components such as brake systems, drill bits, mining equipment, and corrosion-resistant coatings.

Custom 3D Printers Revolutionize the Space Supply Chain

Additive manufacturing technology could enable future astronauts to build any part or piece needed on long-duration missions. A spaceflight crew has to bring with it everything it will need over the course of its journey. In space travel, not only is payload capacity at a premium, but objects carried into space also must be made to withstand the g-force and jarring vibrations of liftoff.
