Emergent Technologies Corp. (ETC) in conjunction with research partners at West Virginia University has developed and recently patented an innovation antenna that promises to revolutionize the science of antenna design, construction and utilization. The antenna, labeled the Countrawound Toroidal Helical Antenna (CTTHA), offers a number of significant advantages over conventional antennas. The CT ...

Space based lidar systems for the remote sensing of Ozone require high-power, high-efficiency lasers operating in the ultraviolet. Diode-pumped solid-state lasers are the primary candidates for this application. Operation in the ultraviolet is typically achieved through two or three frequency conversion steps using nonlinear optical materials. This reduces the efficiency of the laser systems placi ...

An opportunity exists to combine the structural elements of advanced launch vehicles with their thermal protection system (TPS) to create an integrated system, free of parasitic stand-offs and supports. An attractive approach, based on the marriage of two exciting technologies: continuously-brazed aluminum matrix composites (AMCs) and thermally-insulating carbon foam, can result in a more weight e ...

NASA has a critical need for intelligent change detection algorithms andgeoprocessing techniques for digital imagery archives of earth sciencedata obtained from satellites and aerial platforms. Currently, the changedetection process is slow, labor-intensive, and costly. Change detectionmethods that rely on pixel differencing detect all changes between imageryand are thus not well suited for detect ...

Dynamically certified seats (16g seats) are being fielded in all jet transports certified since 1988. In addition, the airlines are steadily replacing their older seats with 16g compatible seats in the older aircraft certified prior to that date. The implementation of the dynamic seat requirements has encountered one unanticipated problem. Under normal use, seat cushions must be replaced with iden ...

The global political structure has changed dramatically since the breakup of the former Soviet Union. World changes have caused the U.S. to reprioritize its National hypersonic needs. The United States government has looked to the needs of the future, and the hypersonic aeorospace plane is one of the systems included in alternative force structures. One of the hypersonic aerospace plane concepts w ...

S&K Electronics is proposing a visual programming environment for developing expert systems in CLIPS. This project will be known as the Visual Expert System Programming Resource, or VESPR. The visual environment will provide a graphical interface for easily capturing knowledge and converting it into the appropriate language constructs; it will also provide visualization of the system being develop ...

Nonlinear optical (NLO) materials play a critical role in current solid-state laser systems enabling broad tunability and operation at wavelengths not accessible by available laser gain media. At the same time, NLO materials limit the longevity and efficiency of these laser systems due to low damage thresholds, poor optical quality and small nonlinearities. As a result, new NLO materials are requi ...
