Multiple-Cone Sunshade for a Spaceborne Telescope
|
|
Date added: 01/02/2008 |
|
V-groove radiator technology is applied to large telescope sunshade to provide thermal isolation to the telescope from solar heat. This new application of the v-groove
heat rejection system provides a cocoon to protect the telescope from this heat during maneuvers. |

Nuclear-Spin Gyroscope Based on an Atomic Co-Magnetometer
hot!
|
|
Date added: 01/02/2008 |
|
We describe a nuclear spin gyroscope based on an alkali-metal–noble-gas co-magnetometer. An
optically pumped alkali-metal vapor is used to polarize the noble gas atoms and detect their gyroscopic precession. |

Mosaic-Detector-Based Fluorescence Spectral Imager
|
|
Date added: 12/03/2007 |
|
A totally new fluorescence detection scheme is used to
overcome problems; a molecular fluorescence spectrum is imaged by a novel mosaic-structured hyperspectral detector array. Each detector in the array consists of a thin film filter and a Si CCD/CMOS tailored to respond to a specific range of wavelengths.

Multiple-Parameter, Low-False-Alarm Fire-Detection Systems
|
|
Date added: 12/03/2007 |
|
A multi-parameter, microsensor-based low-false-alarm fire-detection system (MMFDS) has been developed and demonstrated. Under false alarm and actual fire conditions, the new technology demonstrated a zero false alarm rate in contrast to a conventional system, which consistently triggered false alarms, while both systems consistently detected fires. |

Cryogenic Shrouds for Testing Thermal-Insulation Panels
hot!
|
|
Date added: 11/01/2007 |
|
Cryogenic shrouds were required for two test configurations Titanium (Ti-6A1-4V) wide panel dog bone and Aluminum Lithium (2195-T8) wide panel standard wide panel configurations. Each cryogenic shroud
design is required not to introduce any measurable loads into the wide panel test article during mechanical
induced loads. |

Portable Microleak-Detection System
hot!
|
|
Date added: 11/01/2007 |
|
The measurement of micro-leaks, which are too small to be detected with soap-bubble techniques, is a complicated task. For the case where micro-leak detection is required for very complex geometric shapes, which are loaded with complex mechanical loads and are at extreme temperatures, the describe innovation is an effective and efficient system. |
