An open problem confronting Uninhabited Tactical Aircraft (UTA) is the control concept for their successful operation in combat. Unlike reconnaissance UAVs, it will not be practical to operate UTAs with fully pre-programmed missions nor will it be possible to continuosly fly with them from remote cockpits. A new control paradigm is needed. One that supports a full range of intervention from dir ...

BioMedical Enterprises, Inc. (BME) and NASA Ames Research Center (NASA ARC) are developing NASA's aerospace insulation materials for use as an osseous scaffolding to facilitate and support bone wound healing and regeneration. Fibrous reusable composite insulation (FRCI) developed by NASA for use on the space shuttle was modified to promote bone ingrowth and will be evaluated for its ability to fo ...

This SBIR Phase I program will test the feasibility of achieving a high effective radar cross section over extremely wide bandwidth in a small, low-cost, RF repeater module, using a retrodirective array of a very small repeaters. The array factors effectively multiply the RF characteristics of a single channel to realize high array gain and power using low-performance amplifier. An integral goal ...

Microwave resonators of linear dielectrics for wireless applications have been fabricated in bulk form using conventional ceramic processing in the current commercial market. Machining and fine polishing are frequently required for dimension control and surface finish in addition to the inherent unfeasibility to fabricate miniaturized electronic circuits. It is vital to develop a suitable thin f ...

One approach to wider use of mixed mode technology requires polymer-based packaging materials, which place greater demands on the thermomechanical performance of the package design. Electronic Packaging Services (EPS) proposes to develop a commercial instrument for the experimental measurement of out-of-plane thermal displacements in populated mixed mode electronic assemblies. The system will be ...

Electronic Packaging Services (EPS) proposes to develop a commercial instrument for the experimental measurement of out-of-plane thermal displacements for large area electronic substrates. The system will be based on shadow moire, a full-field non-contact optical technique. Phase stepping analysis, which convolutes multiple moire fringe images with fixed phase differences between them, extends t ...
