Chemochromic Hydrogen Leak Detectors

At NASA, hydrogen safety is a key concern for space shuttle processing. Leaks of any level must be quickly recognized and addressed due to hydrogen’s lower explosion limit. Chemochromic devices have been developed to detect hydrogen gas in several embodiments. Because hydrogen is odorless and colorless and...

A method of calculating (usually for the purpose of maximizing) the power-conversion efficiency of a segmented thermoelectric generator is based on equations derived from the fundamental...

Mechanical Mounting/Connection/Release System

The internal mechanism of the connector part of this system works to maintain positioning repeatability and rigidity, and compensates for wear over time, while both the connector and receiver are tapered in two planes to assure repeatable positioning. Together, the two form a rigid connection that...
