Coming Soon - Compact Vibration Damper

Do you have a need to reduce vibration in high performance structures? Then, you’ll want to attend this NASA Tech Briefs Webinar!NASA Langley Research Center has developed a compact tuned damper that reduces vibration occurring at a fixed frequency. Structural vibrations frequently need to be damped to prevent damage to a structure. Tuned dampers reduce vibration of the base structure by the dissipation of energy. The magnitude of the dissipated energy is proportional to the square of the displacement or velocity of the tuned mass, which in turn is proportional to the range of motion.

Smart Image Enhancement Process

Applications include improving pilot vision, real-time digital enhancement of videos, medical imaging, and thermal and night vision for surveillance systems. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center researchers have developed an automatic measurement and control method for smart image enhancement. Pilots, doctors, and photographers will benefit from this innovation that offers a new approach to image processing. Initial advantages will be seen in improved medical imaging and nighttime photography. Standard image enhancement software is unable to improve poor quality conditions such as low light, poor clarity, and fog-like conditions. The technology consists of a set of comprehensive methods that performs well across a wide range of conditions encountered in arbitrary images. Conditions include large variations in lighting, scene characteristics, and atmospheric (or underwater) turbidity variations. NASA is seeking market insights on commercialization of this new technology, and welcomes interest from potential producers, users, and licensees.

Compact Thermal Neutron Imaging System Using Axisymmetric Focusing Mirrors

This technology uses grazing incidence reflective optics to produce focused beams of neutrons from commercially available sources. Marshall Space Flight Center, Alabama NASA’s Marshall Space Flight Center has developed novel neutron grazing incidence optics for use with small-scale portable neutron generators. The technology was developed to enable the use of commercially available neutron generators for applications requiring high flux densities, including high-performance imaging and analysis. Nested grazing incidence mirror optics, with high collection efficiency, are used to produce divergent, parallel, or convergent neutron beams. Ray tracing simulations of the system (with source-object separation of 10 m for 5 meV neutrons) show nearly an order of magnitude neutron flux increase on a 1-mm-diameter object. The technology is a result of joint development efforts between NASA and MIT researchers seeking to maximize neutron flux from diffuse sources for imaging and testing applications.

Two- and Three-Dimensional Near-Infrared Subcutaneous Structure Imager Using Adaptive Nonlinear Video Processing

The battery-powered system uses off-the-shelf near-infrared technology that is not affected by melanin content, and can also operate in dark environments. John H. Glenn Research Center, Cleveland, Ohio Scientists at NASA’s Glenn Research Center have successfully developed a novel subcutaneous structure imager for locating veins in challenging patient populations, such as juvenile, elderly, dark-skinned, or obese patients. Spurred initially by the needs of pediatric sickle-cell anemia patients in Africa, Glenn’s groundbreaking system includes a camera-processor-display apparatus and uses an innovative image-processing method to provide two- or three-dimensional, high-contrast visualization of veins or other vasculature structures. In addition to assisting practitioners to find veins in challenging populations, this system can also help novice healthcare workers locate veins for procedures such as needle insertion or excision. Compared to other state-of-the-art solutions, the imager is inexpensive, compact, and very portable, so it can be used in remote third-world areas, emergency response situations, or military battlefields.
