The novel gold-on-polymer sensors have been successfully operated and regenerated to detect organic solvents and Hg at ppm/ppb levels required by NASA.

The bidirectional pressure regulator is a flow control device that controls the flow and pressure of fluids that are moving through it. The unique feature of this control is that it is capable of controlling the pressure on either side of the control to a given setpoint at any given moment in time. The regulator works with gases and liquids.

The invention consists of an incandescent lamp of tiny dimensions and method of fabricating. The package is closed with a transparent window normally used for ultra-violet erasing of volatile electronic memories.

This technology will enable cost-effective "metrology webs," in which tens or hundreds of measurement beams are deployed to monitor the dimensional stability of an instrument or structure with subnanometer accuracy and minimal footprint.

This document presents various aspects for vicarious radiometric calibration of airborne and spaceborne sensors of visible and infrared radiation. The methodology reported is used in place of laboratory calibration.
