Wireless, One-way, Sensor to Base Station Monitoring System for Explosive and Non-hazardous Environments

Jensen S.L., NASA - Stennis Space Center, US

The technology developed is a monitoring system that includes a base station and at least one sensor unit mounted at some distance away, which is in wireless, one-way communication with the base station. The sensor [...]

In Situ Health Monitoring of Piezoelectric Sensors

Jensen S.L., NASA - Stennis Space Center, US

The technology developed is an in-situ measurement system for monitoring the performance of piezoelectronic sensors, particularly accelerometers. With this technology, characteristics such as resonant frequency, response, cable status, connectivity, bonding and linear range, can be [...]

Measurement of O-phthallaldehyde (OPA) by High Pressure Liquid Chromatography (HPLC) with Post Column Derivatization

Watkins A.E., Butler T., Dees D., NASA - Stennis Space Center, US

O-phthaldehyde (OPA) is commonly used as a disinfectant that demonstrates microbicidal activity against a range of microorganisms. The Internal Active Thermal Control System (IATCS) is a water based system that helps facilitate heat transfer aboard [...]

Conical, Floating Piston Isolation Valve

Farner B.R., NASA - Stennis Space Center, US

This valve consists of a hollow, moveable floating piston pressed against a stationary solid seat, and can use the working fluid or an external pressure source to seal the valve. This open/closed valve has a [...]
