Development of an Optimal Bioaerosol Sampler with enhanced optical triggering capability is proposed, following a highly successful Phase I effort that clearly demonstrated feasibility. The threat of a bioaerosol attack can be partially mitigated by deployment of a cost-effective sensor network. High priority programs, such as BioWatch and Portal Shield will benefit from a sensor compliant to Join ...

Bearing failure in satellite applications is related to lubricant starvation rather than fatigue, and health monitoring systems for these applications must be able to observe subtle changes related to lubrication state. Phase I included an experimental study to identify candidate monitoring approaches, and the data collected confirmed that cage motion characteristics and instability are highly sen ...

Lubrication problems in rolling element bearings are the leading cause of failure in spacecraft momentum/reaction wheels, control moment gyros, gimbals, and similar applications. Condition monitoring technologies developed for terrestrial or aircraft applications are not adequate due to unique spacecraft conditions and the need to prevent rather than just detect damage. Sentient Corporation, in co ...
