The NIST patented six-degree of freedom micropositioner technology associated with this subtopic has been identified by E M Optomechanical, Inc. (EMOM) as a technology that could be incorporated into the company¿s long-working distance interference microscopes. A key element in these microscopes is a piezo-actuator device, installed in a manual pitch/yaw mount, which translates a small flat mirro ...

Over 10 million coral specimens a year are traded in the +$100 million/year ornamental-recreational aquaria industry. Over ninety percent of commercial coral specimens come from some form of mass harvesting of wild corals from coral reefs. This can have a detrimental impact to coral reefs. We have invented a method of perpetual propagation of corals through tissue engineering. Hundreds to thou ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

American health care is in the midst of momentous change. Quality improvement principles are being used increasingly to enhance productivity and efficiency of health care delivery and to help contain costs. In producing patient outcomes and resource utilization measures, it is vital to control appropriately for case mix (i.e., differences in patients due, e.g., to illness severity) in the predicti ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...

The objective of the proposed program is to address the high service costs of the current U.S. Navy fleet of aircraft by developing a distributed optical fiber sensor system that will help reduce the costs associated with corrosion damage and extend the lifetime of existing aircraft. Annual corrosion of Navy metallic structures has been estimated as high as $1 billion. Additional costs aris ...

The near-field scanning optical microscope can supply information on the shape and electrical properties of surfaces with nanometer resolution. The quantitative interpretation of images is difficult because of the difficulty of electromagnetic field solutions in the near-field limit. We propose to supply software to aid in this analysis. The finite-element programs generate two and three-dimension ...

A growing number of fire fighters are suffering third degree burns; this has led to questions about the adequacy of thermal protective performance (TPP) measurements for protective clothing. A new heat flux sensor, whose response approximates that of skin, will be developed to provide better measurements of heat transfer in TPP tests. This sensor will be used with nonlinear parameter estimation an ...
