Friction Tester

Paul N. Gardner Co. (Pompano Beach, FL) offers a compact CFT friction tester that provides detailed information of the slip characteristics of packaging material. Surface slip is a key factor when printing, erecting, or filling packaging materials on an automatic line. The CFT measures both static and dynamic coefficients of friction. A sample of 2.5 × 2.5" with a weight acting over the entire surface area is moved over another sample at a given speed. Static and dynamic coefficients of friction (COF) are automatically calculated and displayed on-screen. Features include graphical representation of forces during test, and pre-loaded ISO/ASTM/TAPPI test methods. For Free Info Visit http://info.hotims.com/61064-404

Signal Analyzer

The MS2840A signal analyzer from Anritsu (Richardson, TX) features frequency coverage of 9 kHz to 44.5 GHz and close-in SSB phase noise performance. Frequency coverage can be extended to the millimeter wave (mmWave) range. The analyzer can conduct wideband and narrowband measurements on next-generation 4G/5G designs, micro wave and mmWave wireless backhaul, 79 GHz band automobile radar, satellite communications, and VHF/UHF Private Mobile Radio (PMR). The unit’s oscillator achieves phase noise performance of –123 dBc/Hz at 1 GHz measurement frequency, and 10 kHz offset frequency. For Free Info Visit http://info.hotims.com/61064-405

Precise Measurements on Earth Enable Further Exploration in Space

Measurement is the first step to success. If you can’t measure something accurately, it can’t be understood or improved. That is especially true for the spacecraft rockets and engines designed to operate under extreme temperatures and pressures at liftoff, or space stations the size of a six-bedroom house that must support people living and working in space for years.

Next-Generation Infrared Technologies Solve High-Speed Automotive Testing Challenges

Higher-speed IR cameras can improve design phase testing. Product research and development on internal combustion engines, brake rotors, tires, and high-speed airbags are just a few of the areas that truly benefit from high-speed, high-sensitivity thermal characterization testing. Unfortunately, traditional forms of contact temperature measurement such as thermocouples are not practical to mount on moving objects, and non-contact forms of temperature measurement such as spot guns — and even current infrared (IR) cameras — are simply not fast enough to stop motion on these high-speed targets in order to take accurate temperature measurements.

Creating Advanced Dosimeters Requires Thorough Inspection of Small Components

The McMaster University students will launch the small satellite into low Earth orbit to study the effects of ionizing radiation on the human body. Recent advancements in space technology have resulted in space exploration becoming a rapidly growing field, and the desire for human space exploration is drastically increasing. Previous manned missions include flights to low Earth orbit (LEO), such as to the International Space Station (ISS); however, upcoming flights are planned to go beyond LEO, such as to asteroids and eventually Mars. A major consideration in such missions is that the space environment is significantly different from that of Earth, especially with respect to the radiation environment. This drastic difference results in concerns regarding radiation dose.

In-Flight Pitot-Static Calibration

This precise yet time- and cost-effective method is based on GPS technology using output error optimization. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center has developed a new method for calibrating pitot-static air data systems used in aircraft. Pitot-static systems are pressure-based instruments that measure the aircraft’s airspeed. These systems must be calibrated in flight to minimize potential error. Current methods — including trailing cone, tower fly-by, and pacer airplane — are time- and cost-intensive, requiring extensive flight time per calibration. NASA’s method can reduce this calibration time by up to an order of magnitude, cutting a significant fraction of the cost. In addition, NASA’s calibration method enables near-real-time monitoring of error in airspeed measurements, which can be used to alert pilots when airspeed instruments are inaccurate or failing. Because of this feature, the technology also has applications in the health usage and monitoring (HUMS) industry. Flight test engineers can be trained to use this method proficiently in 12 days without costly specialized hardware.

Real-Time Radiation Monitoring Using Nanotechnology

Ames Research Center, Moffett Field, California NASA has patented a unique chemical sensor array leveraging nanostructures for monitoring the concentration of chemical species or gas molecules that is not damaged when exposed to protons and other high-energy particles over time. The nanotechnology-enabled chemical sensor array uses single walled carbon nanotubes (SWCNTs), metal catalyst-doped SWCNTs, and polymer- coated SWCNTs as the sensing media between a pair of interdigitated electrodes (IDE). By measuring the conductivity change of the SWCNT device, the concentration of the chemical species or gas molecules can be measured. These sensors have high sensitivity, low power requirements, and are robust and have a low manufacturing cost compared to other commercial chemical sensors for detection of trace amount of chemicals in gasses and liquids.
