A previously developed video-oculography system has been enhanced for use in measuring vestibulo-ocular reflexes of a human subject in a centrifuge, motor vehicle, or other setting. The system as previously developed included a lightweight digital video camera mounted on goggles. The left eye was illuminated by an...

A system has been designed to reduce the hydrogen molecule content in inert gases that are used for shielding the welding arc and molten weld area during the manual fusion, automated welding, and induction brazing process. Two desiccant pipeline dryer cartridges are connected together using either...

Copper tubes having diameters between about 100 and about 200 nm have been fabricated by electrodeposition of copper into the pores of alumina nanopore membranes. Copper nanotubes are under consideration as alternatives to copper nanorods and nanowires for applications involving thermal and/or...

Flow-splitting and flow-mixing thermally actuated spool valves have been developed for controlling flows of a heat-transfer fluid in a temperature-regulation system aboard the Mars Science Laboratory (MSL) rover. Valves like these could also be useful in terrestrial temperature-regulation...

Cylindrical optics module assembly machines ABTech Swanzey, NH 603-358-6431 www.abtechmfg.com ABTech has completed the first of two cylindrical optics module assembly machines for Columbia University’s Nevis Astrophysics Laboratory. The multi-axis air bearing machine platforms are...

Charge coupled device (CCD) imaging sensors e2v Chelmsford, UK 44 (0)1245 493493 www.e2v.com e2v CCD imaging sensors were launched recently on the Space Shuttle Atlantis as part of a mission to upgrade and repair the Hubble Space Telescope. The imaging sensors equip the Wide Field Camera 3...

This technology takes ZDDP — Zinc Dialkyl Dithiophos - phate, an anti-wear oil additive — and enhances it by adding fluorine to the chemical backbone. The resulting new molecule improves engine fuel economy by 3%, reduces engine wear from that available with conventional ZDDP, and...

Successful performance of BFM (Basic Flight Maneuvers) presents the greatest challenge facing combat pilots. Acquiring and maintaining the required skills for dogfights is a long, complicated and costly process. The solution is a system that provides automatic assessment of a situation and automatic recommendation...

A company seeks technologies that enhance the duration that herbicides, insecticides, fungicides, and similar products are held at a targeted depth within the top layers of soil. Duration should be between 30 and 60 days. The targeted depth varies with the crop plant,...
