Shape Memory Alloy Rock Splitters (SMARS)
Glenn's revolutionary Shape Memory Alloy Rock Splitters (SMARS) device is fabricated from nickel-titanium-halfnium (NiTiHf), nickel-titanium-zirconium compositions, or a combination. These compositions contain a secondary, nanometer-sized precipitate phase that is produced through processes of compositional...

Low-Light Night Vision Imaging and Video Capture
Conventional night vision goggles all use image intensification (I2) tube technology that multiplies ambient, visible, and near-infrared light several thousands of times, allowing a user to see and operate in very-low-light conditions. One shortcoming of I2 tube night vision devices is that they...

Optimetric Measurements Over Coherent Free-Space Optical Communication
High-precision ranging (optimetric) instruments are highly desired for both space navigation and communications as well as gravitational-based science missions. Traditionally, these measurements are made with instruments solely dedicated to ranging (i.e. Doppler shift of a...
Briefs: Medical
The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface lasers,...
Briefs: Sensors/Data Acquisition
The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to...
Briefs: Transportation
It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...
Briefs: Medical
Spectrometers are widely used for applications such as chemical analysis, remote sensing, quality control, environmental monitoring, spaceborne measurements, and optical measurements. Most spectrometers are...
Briefs: Test & Measurement
The Inductive Non-Contact Position Sensor is a highly accurate sensor for motion control applications. The sensor was designed to monitor the precise movements of an optical inspection system that measured...
Briefs: Communications
There are challenges involved when using magnetically responsive materials to achieve the one-way flow of light in a photonic chip, including the ability to place compact magnets on a chip. In...
Briefs: Photonics/Optics
A blue-light imaging method was developed that can be used to obtain visual data from large test fires where high temperatures could disable or destroy conventional electrical and mechanical sensors. The...
Briefs: Materials
Most naturally occurring materials have a disordered atomic structure that interferes with the propagation of both sound and electromagnetic waves. When the waves come into contact with these...
