NASA’s Marshall Space Flight Center has developed a unique prototype for measuring the liquid level in a tank, employing a novel process. The technology can operate in a wide range of environments, including high and low temperatures and pressures, and is simpler and less expensive than other...

Measurement is vital to any manufacturing business, providing essential information to control processes and verify products. But older co-ordinate measuring machines (CMMs) can become bottlenecks if they fail to keep pace with changing measurement needs. Advances in sensor, metrology software and...

Manufacturers of test equipment for automotive head-up displays (HUDs) have partnered with the Society of Automotive Engineers (SAE) Committee to define standard measurement criteria to assess HUD quality. The new standard (SAE J1757-2 “Optical Metrology for Automotive HUD”) will...

Friction Stir Welding (FSW) is a relatively new solid-state welding process, and many industries are now relying on this technique to produce advanced structures. Industries employing this technique include, but are not limited to, aeronautical, motor vehicle,...

Prior art techniques for testing abrasion resistance, such as the Taber test and the Bayer test, typically use a rubbing or scratching mechanism to test materials for abrasion resistance; specifically, either an abrasive material is rubbed across the test...

Air sampling is used to collect samples of airborne particles present in an environment. Analyses of the air samples can provide information concerning potential exposure to harmful respirable agents. Bioaerosol sampling can be used to identify...
