Defense Advanced Research Projects Agency

The Defense Advanced Research Projects Agency (DARPA) was created with a national sense of urgency in February 1958 amidst one of the most dramatic moments in the history of the Cold War and the already-accelerating pace of technology. In the months preceding the official authorization for the agency's creation, the Soviet Union had launched an Intercontinental Ballistic Missile (ICBM), as well as the world's first satellite, Sputnik 1.

Using Formal Methods for Engineering Embedded Systems

Between 1985 and 1987, a radiation therapy device called the Therac-25 was involved in at least six incidents in which the device delivered massive overdoses of radiation. The patients involved suffered radiation burns and symptoms of radiation poisoning. Three of those patients eventually died, all because of a latent software bug. A race condition had gone undetected. It was a test case no one had thought to define.

Now that metal additive manufacturing (AM) is creating fully functional industrial parts, many OEMs are taking a closer look at how the technology might support their individual production goals. Interest has also been piqued by the commitment to AM of some major companies. “I think the news about the GE Leap engine fuel nozzle really resonated throughout industry,” said Doug Hedges, President and COO of Sintavia LLC, a metal AM service provider for aerospace, defense, and other industries. “That got everyone's attention, and certainly increased the pace of inquiries for us.” The nozzle, produced internally at GE, was the first 3D-printed part certified by the U.S. Federal Aviation Administration (FAA) to fly inside a commercial jet engine.

Asphere Measurement System

The AspheroCheck UP from TRIOPTICS (Weden, Germany) is designed with a completely automated measurement process that requires no manual interaction to accurately measure aspheres. Lenses with aspherical surfaces are frequently used in small, light, high-performance optics to reduce spherical aberration. While the decentration of an aspherical surface can be determined with the centration measurement that is also used for spherical lenses, determining a possible tilt requires an additional, off-axial test.

Lindley Johnson, Planetary Defense Officer, NASA Headquarters, Washington, D. C.

NASA’s Planetary Defense Coordination Office (PDCO), managed at NASA Headquarters in Washington, D.C., is responsible for early detection of potentially hazardous objects, like asteroids and comets, and issuing warnings about their potential impacts. This requires teamwork from observatories around the world. NASA’s Planetary Defense Officer, Lindley Johnson leads the global effort to detect and follow near-earth objects

Product of the Month: July 2017

Tektronix, Beaverton, OR, introduced the TTR500 Series USB vector network analyzer, a USB-based RF test instrument. It includes VectorVu-PC analysis software and built-in bias tee for testing active devices. The 2-port, 2-path S-parameter VNA features 100 kHz to 6 GHz frequency range, 122 dB dynamic range, less than 0.008 dB trace noise, and -50 to +7 dBm output power. The built-in bias tee allows for 0 to ± 24V, and 0 to 200 mA on both ports for active devices. The analyzer operates with any Windows PC or laptop, and VectorVu-PC software controls and calibrates the instrument. For automated test systems in design or manufacturing, the software offers programmatic support for SCPI commands, including command compatibility with common legacy VNAs for integration into existing test systems. In addition, the software offers an offline mode for data analysis with an output file format compatible with common EDA simulation tools. Accessories include a rugged carrying case, rack mount kits, phase-stable cables, attenuators, adapters, and calibration kits.

Photoluminescence Spectrometer (PRIORITY)

Edinburgh Instruments (Kirkton Campus, UK) introduces the FLS1000 state-of-the-art, modular photoluminescence spectrometer. The instrument excels in both steady state and time-resolved spectroscopy. It can be configured for spectral measurements from the ultraviolet to the mid-infrared spectral range, and for lifetime measurements spanning time resolutions over 12 orders of magnitude from picoseconds to seconds. Its ultimate sensitivity for the standard water Raman measurement is >30,000:1.

National Institute of Standards and Technology (NIST)

The National Institute of Standards and Technology (NIST) was founded in 1901, and is now part of the U.S. Department of Commerce. Based in Gaithersburg, MD, it was established to remove a major challenge to U.S. industrial competitiveness at the time — a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals.
