A Strip You Can Rely On: Tips for Designing Blood Glucose Test Strips

  • Magazine Article
  • TBMG-35335
Published 2019-10-01 by Tech Briefs Media Group in United States

When it comes to diabetes management, accurate blood glucose readings are paramount. And when it comes to generating accurate readings, the quality of the test strip is dependent upon the materials used in its design — each layer has to be able to perform its function without interference from other layers or external contamination.

Schlieren System Captures Brilliant Shockwave Images

  • Magazine Article
  • TBMG-35254
Published 2019-10-01 by Tech Briefs Media Group in United States

Supersonic flight over land is generally prohibited because sonic booms created by shockwaves disturb people on the ground and can damage property. Armstrong innovators are working to solve this problem with a novel system for capturing images of shockwaves created by supersonic aircraft. The Background Oriented Schlieren Using Celestial Objects (BOSCO) technology uses a celestial object, such as the Sun, as a background to secure unique, measurable shockwave images of full-scale aircraft. The patented image-processing technology captures hundreds of observations with each shockwave, benefitting NASA engineers in their efforts to develop a supersonic aircraft that will produce a soft “thump” in place of a disruptive sonic boom.

Published 2019-10-01 by Tech Briefs Media Group in United States

An automated system designs and 3D-prints complex robotic parts that are optimized according to an enormous number of specifications. The system fabricates actuators — devices that mechanically control robotic systems in response to electrical signals — that show different black-and-white images at different angles. The researchers 3D-printed floating water lilies with petals equipped with arrays of actuators and hinges that fold up in response to magnetic fields run through conductive fluids (see figure).

Published 2019-10-01 by Tech Briefs Media Group in United States

A new portable sensor can accurately measure patients’ hydration levels using a technique known as nuclear magnetic resonance (NMR) relaxometry. Such a device could be useful for not only dialysis patients but also people with congestive heart failure, as well as athletes and elderly people who may be in danger of becoming dehydrated.

UNIX Tools for Typesetting and Shell Programming

  • Magazine Article
  • TBMG-35256
Published 2019-10-01 by Tech Briefs Media Group in United States

Jet Propulsion Laboratory (JPL) has developed software tools that extend the capabilities of the Groff typesetting system for UNIX. Groff, or GNU Troff, descends from the Troff formatter originally developed at AT&T Bell Labs. It operates on text files containing a mixture of unformatted text and formatting instructions (in the same spirit as HTML or TeX) and produces finished documents in various formats suitable for viewing or printing (PDF, HTML, etc.).

The Challenge of Replacing Hard Chrome

  • Magazine Article
  • TBMG-35359
Published 2019-10-01 by Tech Briefs Media Group in United States

The search for a suitable replacement for hard chrome on aerospace components has been a key supply chain priority for aircraft manufacturers. This is because of the documented health risks to workers and the impact on the environment from exposure to hexavalent chromium, a carcinogen that occurs during the chrome plating process and is the most toxic form of chromium.
