CMOS Cameras

The LX series from Baumer (Radeberg, Germany) features high-resolution CMOSIS sensors, a dual GigE interface, and 240 MB/s bandwidth. The cameras operate with 8-, 12-, and 20-megapixel resolutions. Eight- and 12-megapixel models utilize the CMOSIS 5.5 μm pixel design. The 20 MP model, with 6.4-μm pixel structure, features a low noise of 8 e- and a dynamic range of 66 dB. Because of its standard-compliant Dual GigE interface, the 20-MP GigE Vision camera currently available enables cost-efficient system integration.

Products of Tomorrow: September 2014

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Robots are (Almost) People, Too

Biologically inspired robots have been an ongoing fascination in movies for years. We know that robots can’t cry, bleed, or feel like humans can, and that’s what makes them different. But what if they could think like humans? Biologically inspired robots are being realized by engineers and scientists all over the world. While much emphasis is placed on developing physical characteristics for robots such as human-like faces or artificial muscles, engineers in the Telerobotics Research and Applications Group at NASA’s Jet Propulsion Laboratory in Pasadena, CA, are among those working to program robots with forms of artificial intelligence similar to human thinking processes.

NASA Uses Analysis Software to Assess Orion Crew Module Heat Shield

HyperSizer® composite analysis and structural sizing software Collier Research Corp. Newport News, VA 757-825-0000 www.hypersizer.com Protected by the shell of its huge launch rocket during blastoff, NASA’s Orion Multi-Purpose Crew Vehicle (MPCV) must get back to Earth on its own at mission’s end. The flight plan for this next-generation craft includes a dramatic ocean splashdown reminiscent of the Apollo program that predated the Space Shuttle’s smooth runway landings.

Universal Mechanical Testers for Tribology Testing in the Automotive Industry

Universal mechanical testers provide tribology testing for friction, wear, coatings, and lubrication in macro, micro, and nano regimes. Bruker Nano Surfaces, Tucson, Arizona Very few industries are as affected by strict test standards as the automotive sector. Nearly every automobile component (engine parts, accelerators, clutches, brakes, tires, seatbelts, etc.) must exhibit adequate tribological properties in accordance with ASTM, DIN, JIS, ISO, and other comprehensive international standards. Universal mechanical testers (UMTs) that are able to perform multiple tests in a single platform with interchangeable modules can help manufacturers meet test specifications quickly and economically. For example, crankshafts and camshafts have critical requirements for proper functioning under diverse service conditions. Tests include evaluation of base materials, heat-treated parts, surface coatings, and lubricants. Tests can be run with diverse loads, velocities, and temperatures that simulate actual service conditions using various lubricants and liquids.

Photogrammetric Recession Measurement

This method can be used to measure the recession of ablative materials in insulation coatings, ceramics and composites, arc-jet systems, and soil erosion. Ames Research Center, Moffett Field, California The testing of materials that ablate as a design function requires detailed time history of the ablation process. The rate at which the surface recedes during testing is a critically important measure of the performance of thermal protection system (TPS) materials like heat shields for aerospace vehicles. Photogrammetric recession measurement (PRM) meets these needs by recording the surface of the ablating model during heating in hyperthermal test facilities (arc-jets), using two high-resolution digital cameras capable of recording simultaneously. The cameras are calibrated to yield three-dimensional object space measurement for each stereo pair of images, producing surface recession data over the portion of the model for which both cameras share a view.
