New Standards Developed to Improve Metal Detector Testing

Metal detectors now appear routinely in the entrances of many schools, airports and even houses of worship. They serve as portals to correctional facilities, prisons and courthouses, and guards often wave hand-held models around the bags of incoming ticketholders at sports arenas. The increased usage is making it more important than ever to know that these machines will always work as expected and can be counted on to help detect weapons and other threats. To help meet these demands, scientists at the National Institute of Standards and Technology (NIST) have researched and developed four metal detection testing standards. Three have been published by the ASTM International standards organization and a fourth is still in development.

Streamlining Post-Processing in Additive Manufacturing

Undoubtedly there are many benefits associated with the use of additive manufacturing (AM) as a production technology. On a pan-industrial basis, manufacturers exploit the fact that through the use of AM they can not only build complex parts, in one piece, which were previously impossible, but they can also build stronger, lighter-weight parts, reduce material consumption, and benefit from assembly component consolidation across a range of applications. These advantages have all been well documented during the last 10-20 years as AM has emerged as a truly disruptive technology for prototyping and production, and are invariably seen as being enabled by the additive hardware that builds the parts. In reality, however, this is a partial picture, particularly for serial production applications of AM. AM hardware systems are actually just one part – albeit a vital part – of an extensive ecosystem of technologies that enable AM, both pre- and post-build.

Tips for Reducing Error When Using Eddy Current Measuring Techniques

Inductive eddy current technology is an extremely versatile non-contact method for measuring an object's position, distance, or vibration. Unaffected by environmental contaminants or target finish characteristics, these sensors can operate in a vacuum or in fluids, so they work well for dirty applications, like those with oil or dust present. To get the most out of eddy current sensors, follow these tips for reducing errors that can affect a measurement's accuracy.

The Three Rs of Analog Position Sensor-Based Mechanical Measurements

Those of us old enough to remember the “good old days” recall that grade school focused on learning the 3 R's: reading, ‘riting, and ‘rithametic. In the world of sensors, there are also 3 R's: Repeatability, Resolution, and Response. As important as these sensor parameters are, there is often confusion in the mind of users about exactly what they mean and in what ways they tend to interact with each other. This article will attempt to explain the 3 R's for position sensors and dispel any confusion that might exist.

Research Highlights Future Hypersonic Flight Challenges

Southwest Research Institute engineers are conducting tests that elucidate the conditions a future aircraft may experience traveling faster than 10 times the speed of sound. Because that environment is so unique, recreating realistic flight conditions to test vehicles for hypersonic flight is a challenge.

How to Dismantle a Nuclear Bomb

How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets.

Engineered Resilient Systems

Analyzing large data is the process of methodically and systematically making decisions to reduce incomprehensible datasets down to a manageable size that can be viewed and understood easily. These reductions are made by performing data analytics, producing metrics, identifying patterns, and/or producing any other criteria of comparison that can be mathematically modeled.

Defeating Commercial Drone Threats with Open-Source SDR

It’s nearly impossible to look at technology news without seeing an article about drones. Whether detailing how Amazon wants to use drones to deliver packages or revealing amazing aerial video of drones following Olympic snow-boarders, commercial drones are ubiquitous. Drone emergence has benefited many applications including sports broadcasting and wildlife preservation wilderness surveys. Offering powerful, intelligent software, drones are becoming less expensive and easier to use, with substantial operating range.
