SRD will develop a miniaturized atmospheric gas sensor array and design a gas analyzer (sensor analyzer module, SAM) capable of accurately detecting and autonomously monitoring critical atmospheric gases in enclosed spaces. In this Phase I effort, SRD will use its current, existing technology (miniaturized sensor platform, proprietary SMO sensor coatings and advanced signal processing algorithms) ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...

The recent emergence of the Silicon Drift detector (SDD), for use in Energy Dispersive x-ray Spectroscopy (EDS), has made possible x-ray event streams with input count rates in the range of 1-10 Mcps. Modern digital pulse processors are therefore required to run at fast time constants to achieve reasonable throughput; however, this causes significant coincidence artifacts to appear in the spectrum ...

This NIST Phase 1 SBIR effort will demonstrate the feasibility of low noise single photon up conversion using KTiOPO4 (KTP) or LiNbO3 (LN) or Stoichiometric LiTaO3 (SLT) periodically poled waveguides and an 1800nm pump for a high efficiency single photon detector. The key innovation is using low noise periodically poled waveguides with a long wavelength (1800nm) pump leading to higher efficiency s ...

THIS PROPOSAL IS TO STUDY THE FEASIBILITY OF APPLYING THEORETICAL MODELS OF PERCEPTUAL PROCESSING IN HUMANS TO ESTABLISH BETTER COMMUNICATION OF INFORMATION TO HUMANS FROMTHEIR TECHNOLOGICAL ENVIRONMENT. THIS STUDY WILL DRAW ON THE LITERATURE OF PERCEPTUAL AND NEUROPHYSIOLOGICAL INFORMATION. IT WILL INCLUDE THEORETICAL WORK AND DEMONSTRATION DISPLAYS. THREE AREAS WILL BE CONSIDERED: 1) OPTIMIZING ...

We propose to evaluate tree dominant semantics for description logic integrity constraints, as well as multiple proposals for adding syntax for integrity constraint axioms, to the Web Ontology Language standard, OWL. Further, we propose to implement a semantics, in the form of a syntax compiler and data set validator, in order to establish the feasibility and utility of such work for the validatio ...

Open-ocean finfish aquaculture presents many challenges including net handling, scuba diving in adverse conditions, maintenance, and feeding. In Phase I, Ocean Farm Technologies, Inc. successfully demonstrated the feasibility of pen rotation, which is essential to maintaining a fish pen offshore. Phase II will develop a prototype automated operations system for marine finfish net pens. Automate ...

Ocean Farm Technologies (OFT) proposes to examine using ocean wave energy to power offshore aquaculture. While developing offshore fish farming systems, OFT has recognized a pressing need for non-polluting, low-cost sources of power for system operations and diver support. The greatest need for power is in the form of pressurized air. OFT¿s AquaPodTM containment system utilizes air for posi ...

MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...

THE PROPOSED PROGRAM EXAMINES OPPORTUNITIES FOR LIGHTWEIGHT CONTAINMENT STRUCTURES IN AIRCRAFT AND ROTORCRAFT AND SEEKS TO DEVELOP FIBER REINFORCED MATERIALS AS THE ENERGY ABSORBING CORE OF POTENTIAL CONTAINMENT DESIGNS. THE PROGRAM BEGINS FROM BASELINE DESIGNS FOR FAN CONTAINMENT WHICH EMPLOY PLAIN WEAVE KEVLAR LAMINATES TO ABSORB BLADE FRAGMENT ENERGIES. VARIOUS ADVANCED FIBERS INCLUDING POLYETH ...
