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...

Gated Chopper Integrator (GCI)
Microvolt-level signals require gains of at least a thousand. Offsets and noise in the amplifier chain will be amplified by the same amount, which can saturate the amplifier or swamp the signal so it is not resolvable. Other methods use chopping and/or autozero techniques to lower the offset and noise. The key...
