Coming Soon - What is Measurement Risk?

Do you think your measurement is "In-Tolerance" if the measured value is within the manufacturer's accuracy specification? If the calibration provider is not considering the test uncertainty ratio, chances are your measurements are not what you think they are and it is very likely that you may be making bad measurements.

6 Critical Errors to Avoid in Reusable Packaging Design

Designing a reusable, durable packaging solution for your product or service is much more than picking a type of package and a size. There are many things to consider about how your product will be used, where it will be used, and who will be using it. This list of six common errors will ensure your initial design decisions put you on the path to the most cost- effective case that combines the required protection with superior usability.

Sound-Off: The Imaging Advantages of Blue Light vs. White Light

Digital Image Correlation (DIC) is a non-contact optical method of measuring deformation and strain on a given material. Measurement accuracy, however, depends on contrast, illumination, and light intensity.

A Balancing Act: How Months in Space Impact Astronauts' Performance

When you arrive back on Earth after a year in space, you’re going to feel it.

NASA and Jacob Bloomberg, senior scientist in the Houston, TX- headquartered Johnson Space Center, have been trying to quantify exactly what those effects will be — and how 12 months of microgravity impact an astronaut’s ability to perform simple operational tasks like opening a hatch or climbing a ladder.

Mini Spectrometer Has Big Potential

Researchers have created a miniaturized, portable version of the mass spectrometer, which traditionally has been bulky, limiting its in-field potential. Other smaller spectrometers have been less sensitive and more likely to break down.

Portable Kit Recovers Traces of Chemical Evidence

This measurement kit can recover trace chemicals such as environmental pollutants, and forensic evidence such as arson fire debris.

An arson investigation typically requires collecting one or two liters of ashes and debris from various locations within a fire scene in metal cans similar to those used for paint, and sending the material to a lab. The testing methods typically include gas and liquid chromatography or various versions of spectroscopy, with gas chromatography being the most widely used in fire debris analysis. When the fire debris is received at the testing facility, samples are taken for testing. Sometimes this will involve suspending a strip with activated charcoal in the air or “headspace” directly above the sample in the metal can for a period of time that can vary, depending on the judgment of the analyst, for 2-3 hours or up to 16 hours.

Overspeed Protection for Turbine Flowmeters in Cryogenic Applications

Flowmeters for cryogenic applications often fail in service. Turbine flowmeters in particular fail due to very high speeds encountered during chill-down operations. Very cold, very high-velocity gas causes the turbine to spin uncontrollably, which quickly degrades bearings. Those flowmeters that do not fail are often unreliable, degrading their effectiveness as instrumentation to monitor and control cryogenic propellant loading.

Handheld Device with Reagents for Detection and Diagnostics

The high risk associated with biological threat agents determines that any suspicious sample be handled under strict surety and safety controls, and processed under high-level containment in specialized laboratories. These specialized facilities are complex, very expensive to operate, and need to be staffed by personnel from an extremely limited pool of experts. In addition, safe means of transporting samples suspected of containing highly virulent agents to specialized high-level containment laboratories for analysis is also expensive, requiring, in many countries, the custody of armed personnel. It can be estimated that several million dollars are spent annually worldwide to secure and safely transport an increasing stream of suspicious biological samples that are collected in theaters of war, as well as in domestic environments.
