Unlock the Hidden Potential of Your CMMs

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 controller technology now offer the opportunity to transform existing CMMs, providing greater accuracy, faster measurement, more automation and new capabilities, whilst taking full advantage of CAD-driven programming. In the current economic climate, upgrading makes good economic and ecological sense.

Four Ways to Enable Automated SAE Standard HUD Measurement

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 outline optical measurement geometries and requirements for determining HUD performance using light measurement systems. Although no single system is specified, there are several differentiating features among SAE-compliant systems that greatly reduce HUD evaluation time, enabling automated production-level measurement, ensuring compliance, and limiting cost and time to market.

Handheld Spectral Analyzer for Point-of-Care Diagnostics

A spectral transmission-reflectance-intensity (TRI) analyzer was developed that attaches to a smartphone and analyzes patient blood, urine, or saliva samples as reliably as clinic-based instruments. It is capable of performing thousands of current tests that may be adapted to the device, including an enzyme-linked immunosorbent assay (ELISA) that detects and measures a wide variety of proteins and antibodies in blood, and is commonly used for a wide range of health diagnostics tests. The system is capable of detecting the output of any test that uses a liquid that changes color, or a liquid that generates light output (such as from fluorescent dyes).

On-line Phased Array Ultrasonic Testing (PAUT) System for Friction Stir Welding (FSW)

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, and maritime. As with any welding technique, the quality of a weld must be determined to ascertain reliability and safety. For this reason, a welded structure has to go through a rigorous screening process.

Forward Voltage Short-Pulse Technique for Measuring High-Power Laser Diode Array Junction Temperature

NASA’s Langley Research Center has developed a new technology for measuring the junction temperature of laser diode arrays (LDAs) that can support dramatically improved LDA fault analysis and lifetime estimates. This technology provides better spatial and temporal resolution than spectral chirp or thermal imaging methods, and can be integrated into existing LDA systems, such as laser diode drivers, without significant additional costs (including weight, power, and space). Potential applications include quality control and screening of LDAs for maximum lifetime, optimizing development of operational parameters, or providing real-time operational diagnostics/prognostics.

Apparatus and Method to Test Abrasion Resistance of Material Using Airborne Particulate

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 sample surface, or the test sample is rubbed against an abrasive surface. While these tests do provide valuable data, they do not accurately or reliably predict resistance to impact damage from wind-borne particulate matter. These prior art techniques are typically used to test hard protective coatings to determine their resistance to scratching; however, such protective coatings are prone to shattering upon impact of a fast-moving object, such as a grain of sand.

Miniature Airborne Particle Mass Monitor

Particulate matter (PM) exposure and health effects have become top U.S. environmental research agenda items over the past decade. Environmental epidemiological studies rely on information from both sides of the dose-response equation: risk factor measures and health outcome data. The ability to resolve relationships from environmental data depends upon the quantity, accuracy, specificity, and precision of both. Although health surveillance and data collection methods have improved dramatically through database system advances, the techniques for PM exposure are not adequate.
