"Disposal of spent fluorescent lamps everywhere, and on ships in particular, is made difficult by the hazardous levels of both liquid and vaporous mercury they contain. Existing practice is storing whole lamps for on-shore disposal, which is both expensiveand dangerous - storage space, unnecessary handling, accidental breakage (due to the handling of long tubes of glass in confined areas) with re ...

"The objective of this proposal is to describe an automated (or semi-automated) lightweight, low-cost handling system for lauch & recovery of offboard vehicles which can be fitted to existing Navy ships or designed into new classes of ships. Many of thesystems required for this effort are either in preliminary development of have been developed. It is intended that by combining existing offboard h ...

"A low-cost chemical solution derived material is being proposed as an environmentally-friendly corrosion resistant coating material to combat the corrosion problems faced by the MDA. The coating material is a newly discovered inorganic oxide, calledCerablak, which is amorphous, or glassy, in nature and can be deposited as a hermetic, dense, and pin-hole free film by a simple dip coating, paintin ...

"In a network stack Denial-of-Service (DoS) attack, numerous network packets flood the packet queues on a computer system, rendering the processing software on that machine (the "network stack") incapable of processing normal traffic. (This is not the sameas a network bandwidth attack, in which copious packets overwhelm the capabilities of the data lines in and out of the computer.)We propose to ...

"This Phase II proposal uses multi-axis fiber grating strain sensors to characterize strain fields interior to complex composite materials. Advantages of this approach include the ability to measure transverse strain, transverse strain gradients and axialstrain simultaneously at multiple points along a single fiber line. Models and software will be developed to complement a data base generated t ...

"Single and multi-axis fiber grating strain sensors were used to detect damage in a Phase I composite cryogenic tank. Acoustic signatures were collected from multiple fiber grating sensors during impact. Multi-dimensional strain field measures were usedto measure damage remotely through three cryogenic cycles. The first cycle occurred prior to impact and the second and third after two subsequen ...

"Single and multi-axis fiber grating strain sensors were used to detect delaminations and cut tow damage sites in composite motor casings during Phase I of this program. Acoustic signatures were collected from multiple fiber grating sensors during impactand pressure cycling of the Phase I test article. Multi-dimensional strain field measures were used to measure damage remotely. The Phase II ef ...

"This Phase I SBIR will study the potential of a multi-axis fiber grating strain sensor system that is capable of monitoring strain internal to a solid rocket motor bondline. This multi-axis technology would allow unique multidimensional strain fieldanalysis via a non-intrusive, embedded optical sensor. This technology could not only be used to monitor solid rocket motors, but has a wide range of ...

"Blue Road Research intends to extend the use of both high reflectivity, wavelength multiplexed grating sensors and low reflectivity, interferometrically multiplexed grating sensors to measure multi-dimensional strain fields in bonded joints in aerospacestructures, and use this strain field information to monitor structural integrity over the vehicle lifetime. In addition, Blue Road Research in ...
