Enabling High Performance Instruments for Astronomy and Space Exploration and ALD

Benefits of ALD for NASA instruments and applications: a) Ultrathin, highly conformal, and uniform films over arbitrarily large surface area. b). High quality films (density, roughness, conductivity, etc.) . Angstrom level control of stoichiometry, interfaces, and surface properties: 1) Multilayer nanolaminates/nanocomposites. 2) Low temperature surface engineering. Flight applications enabled by ALD: a) Anti-reflective coatings/Mirrors/Filters/Optics for UV/Vis/NIR Detectors. b) Superconducting Films for Submillimeter Astronomy.

Real-time non-invasive eyetracking and gaze-point determination for human-computer interaction and biomedicine

Eyetracking is one of the latest technologies that has shown potential in several areas including human-computer interaction for people with and without disabilities, and for noninvasive monitoring, detection, and even diagnosis of physiological and neurological problems in individuals.

Experimental Verification of the Pulse Shepherding Concept in Dispersion-Shifted Single-Mode Fiber for Bit-Parallel Wavelength Links

A new way to dynamically control in-flight pulses by a co-propagating shepherd pulse in a wavelength divsion multiplexed (WDM) single-mode fiber system was proposed at the MPPOI '96 Conference. That system functionally resembles an optical fiber ribbon cable, except that all the bits pass on one fiber optic waveguide.
