We propose a high performance library of signal processing tools that incorporate a newly developed technique known as fluctuation enhanced sensing (FES) to enhance the novel microsensor developed at NIST. Our goal is to improve the performance of the NIST sensor from two angles. One is to apply our existing proven algorithms to the NIST data. The other one is to incorporate advanced FES concept t ...

RoadNarrows proposes a novel architecture to be implemented in a 6DOF vision system with applications in autonomous robotics. The system will report objects of interest along with location and pose information to a supervising computer. This system will be built around an advanced 3D vision platform that can deliver multiple video streams and 3D spatial measurements. The sensors will deliver high- ...

G2 proposes to develop an intuitive, interactive SCAP content creation and editing utility that will provide a user-friendly operating environment. The promise of security automation offers the opportunity for great advances in software assurance, security governance/reporting, and ongoing monitoring activities. Hindering that promise is the fact that current data exchange protocols are cumbersome ...

Computational tools that accurately predict the performance of electric propulsiondevices are highly desirable and beneficial to NASA and the broader electric propulsioncommunity. The current state-of-the-art in electric propulsion modeling relies heavily onempirical data and on numerous computational "knobs". In Phase I of this project, wedeveloped the most detailed ion engine discharge chamber m ...

Electrodynamic tethers are optimally suited for use in Low-Earth-Orbit (LEO) to generate thrust or drag maneuver satellites. LEO region is polluted with space debris from the left over of rockets and abandoned satellites. It becomes important to clean them, i.e., de-orbit and ED tethers are promising for such applications. ED tethers are operating without propellants, so less polluting in our spac ...

We propose novel and real-time smart software tools to process spectroscopy data. Material abundance or compositional maps will be generated for rover guidance, sample selection, and other scientific missions. First, we propose a novel anomaly detector called clustered kernel Reed-Xiaoli (CKRX) algorithm. This tool was developed by us, is fast, and can achieve very high anomaly detection rate in ...

This proposal describes the preliminary development of surface acoustic wave (SAW) based hypergolic fuel sensors for NASA application to distributed wireless leak detection systems. SAW devices are a platform technology for passive wireless sensing of numerous possible measurands. ASR & D and its collaborators have demonstrated passive wireless sensors using SAW devices, for applications includi ...

The proposed project will develop a set of at least 100 passive wireless surface acoustic wave (SAW) RFID sensor-tags for near-simultaneous remote monitoring of groups of conventional sensors. Coded SAW sensor-tags have been demonstrated by ASR & D under NNX09CE49P to be capable of providing a passive wireless interface to external sensors, including switches, thermistors, and strain gages, as we ...

NASA is interested in advancing green technology research for achieving sustainable and environmentally friendly energy sources for both terrestrial and space applications. It has been reported that thermo-electric power generation (TEPG) can contribute to electrical power generation scavenged from waste heat sources. Significant advantages to TE technology include: no moving parts, low-weight, mo ...

Fiber reinforce polymer (FRP) composite materials are seeing increasing use in the construction of a wide variety of aerospace structures. However, uncertainties regarding the material's impact durability continue to plague the FRP composites community. To address this need, ADA Technologies, Inc. (ADA), Littleton, CO, in partnership with the University of Delaware's Center for Composi ...
