Title:3D Corrosion Mapping System for Complex Curved Surfaces
Abstract:SBIR Topic NAVY 09-093 clearly describes the roadblocks that must be overcome in order to provide 3D surface mapping of corrosion on complex curved surfaces. Barron Associates and Southwest Research Institute propose innovations in sensing, control, and signal processing that will serve as the foundation for a new 3D corrosion mapping system (3DCMS). The cornerstone of the 3DCMS is the integrated optical module (IOM). The IOM is a new high-resolution sensor architecture featuring an extremely compact head unit suitable for inspection of small diameter interior cylinders and exterior surfaces with a variety of fillets and transition radii. Accompanying designs of the intelligent feedback control system and 3D image registration techniques are of nearly equal importance and also require significant innovation. The actuation system will be based on commercially available robotic manipulator technology in order facilitate prototype demonstration. In order to fully satisfy the requirements of mapping an unknown surface of complex geometry without models of the nominal shape while minimizing operator interventions, an adaptive-autonomous 3D path planning algorithm will be integrated in the design. The Phase I effort will focus on design of the IOM and prediction of the feasible performance of the feedback control system and image registration algorithm.

Title:High Resolution Corrosion Mapping via In-Situ White Light Interferometry for Complex Geometries
Abstract:Corrosion damage costs the Navy time and money by requiring critical components to be monitored for fatigue on a scheduled basis rather than by need. When quantitative analysis of corrosion data is obtained, lifetime models and corresponding depot level re- work can be planned appropriately while maintaining fleet readiness. White light interferometry (WLI) uses white light interference patterns to determine surface features with vertical nanometer resolution. WLI has been shown to provide pitting and surface depth erosion of corroded structures. Luna Innovations Incorporated proposes to develop a conceptual design for a portable WLI that is capable of measuring the inside diameter of shafts and other complex geometries of mission critical structural components via three approaches 1) improve the situation awareness of the optical head to improve the accuracy of portable image acquisition, 2) utilize software programming to analyze a region of interest to reduce sampling time and file size and 3) a novel optic design to measure fillets and other high slope regions. It is anticipated that the conceptual prototype will be built and demonstrate a design that is simple to employ with improved resolution.

Title:Material Classification for Physics-Based Sensor Simulation Using Stereo-Pair Imagery
Abstract:The recent deployment of high-resolution stereo-imaging sensors aboard satellites affords a unique opportunity to to derive more realistic material classified terrain terrain databases for physics-based sensor and mission trainers. JRM is uniquely experienced and qualified in the many technology areas required to support this topic: EO, IR and radar signature synthesis and phenomenology understanding, material-classification algorithm and software development, real-time sensor simulation product development, an established network of sensor simulation customers and distributors, maintenance of a material measurement and spectrometry laboratory, partnerships with satellite imagery providers, and expertise in state-of-the-art GPU shader technology. In this Phase I SBIR, JRM Technologies proposes to explore and design a comprehensive set of innovations for exploiting stereo-pair satellite imagery toward improved physics-based simulation for war-fighter sensor training. JRM proposes the following specific innovations: 1. Fast, efficient algorithms and software for processing stereo-pair imagery into 3D-point clouds; 2. Improved material classification techniques and software for leveraging this 3D stereo- pair-derived data; 3. GPU-techniques for improved EO, IR, and radar channel simulation which leverage stereo-pair-enhanced material-classified terrain databases; and 4. Improved material data libraries for producing and exploiting stereo-pair-enhanced material-classified terrain databases. As an option, JRM also proposes a Proof of Concept demonstration with stereo pair imagery.

Title:Material Classification for Physics-Based Sensor Simulation Using Stereo-Pair Imagery
Abstract:In order to generate geospecific materialization and textures for synthetic scenes derived from satellite based stereo imagery, a complete model or description of the reflectance is required for surfaces in that scene. Surface reflectance accounts for various characteristics the human eye uses to distinguish objects in natural or image scenes. Attributes include: material type (metal, plastic, vegetation etc.), shape, specular versus diffuse reflection, glossiness and surface texture are examples. Reflectance is typically characterized by the Bidirectional Reflectance Distribution Function (BRDF) which describes the differential change in spectral radiance reflected (dLr (?r??r)) off a surface with respect to incident spectral irradiance dE(?i??i) to that surface. SimWright Inc. applies twelve years experience in remote sensing, 3D visual simulation, stereo photogrammetric image processing (including tool development) and systems integration to propose a remote sensing approach to measure BRDF for physics-based material classification and synthetic texture generation. The approach is built upon extensive airborne and ground based testing (model validation) which will measure target objects’ spectral radiance in elevation and azimuth. Skydome irradiance will also be characterized. Accurate BRDF models can be incorporated into physics based modelers to generate 3D terrain surfaces and objects for IGs.

Title:Material Classification for Physics-Based Sensor Simulation Using Stereo-Pair Imagery
Abstract:Current simulators can display very detailed imagery over very large geographic training areas in both visual and sensor channels. To provide a high-fidelity sensor channel, the simulation must be physics-based, and must rely on knowledge of the material properties of the simulation area. The proposed work includes the development and evaluation of algorithms for an advanced classifier and feature extractor that uses both color/multispectral imagery and digital elevation maps. It is specifically targeted to exploit the stereo imagery from the latest generation of earth imaging satellites. The extractor uses an initial multi-scale object-based process to segment the image, followed by an expert system for object classification and feature extraction. The proposed option tasks include the exploitation of height and intensity texture, and the extraction and representation of spatial variability within a material class.

Title:Innovative Analysis Tool for Damage Growth From Loaded Composite Fastener Holes
Abstract:A software tool for residual strength and life prediction of composite bolted joints will be developed by enhancing and integrating an existing mesh independent delamination and matrix cracking network model in ABAQUS. The tool will be able to model arbitrary location, size of damage, and geometric configuration of a composite structure with fastener holes without user intervention or remeshing. High computational efficiency and modeling fidelity is achieved via the integration of the discrete crack network model with a hybrid fatigue damage model within ABAQUS’ computational framework. Global Engineering and Materials, Inc. (GEM) has secured commitments for technical support from UDRI, LM Aero, and SIMULIA, who will provide existing solution modules, supporting data, customization plug-ins, and expertise. In addition, Dr. Iarve from UDRI will provide GEM with his stand alone 3D bolted joint stress analysis and damage growth prediction tool that has been in development for more than 10 years under the sponsorship of Air Force and NASA. The multi-faceted feasibility study consists of developing a method that will enable the prediction of multi-site, multi-mode damage initiation, propagation, and interaction in composite bolted joints subjected to monotonic and fatigue loading.

Title:Innovative Analysis Tool for Damage Growth From Loaded Composite Fastener Holes
Abstract:For the Phase I effort, Global Engineering and Research Technologies (GERT) will develop a validated analysis tool to predict damage initiation and growth as well as residual strength composite multiple-lap joints with many staggered bolts. The analysis tool will be based on the merger of (local) classical continuum theory and (non-local) peridynamic theory. The Phase I effort will consider published experimental investigations in the validation of the proposed approach. The predictions will be compared against the measured failure loads and photo micrographs of failure modes. This effort will also demonstrate the feasibility of the proposed method by considering bolted lap joint configurations with multiple staggered bolts and multiple layers of different composite materials. Finally, the proposed method will be integrated into user friendly software modules that can be used to perform damage growth and life prediction of loaded holes in composite laminates.

Title:Innovative Analysis Tool for Damage Growth From Loaded Composite Fastener Holes
Abstract:We propose the development of a validated analysis tool to predict damage growth and useful life of loaded fastener holes in laminated composites. The objectives of Phase I are (1) to develop and verify a concept for comprehensive damage initiation and growth models applicable to loaded fastener holes; and (2) define a conceptual design for a prototype software/tool to perform damage growth and life prediction for loaded holes in composite laminates. The Numerical Technology Company team accumulated significant expertise and experience in the durability and damage tolerance technology development for composites and demonstrated unique abilities to predict damage and useful life through the rotorcraft industry verification. The team members developed a methodology for measurement of key matrix-dominated material properties as well as developed finite element-based techniques enabling accurate failure predictions for composites under quasi-static and fatigue loading. The proposed effort will further expand and verify/validate the durability and damage tolerance technology for loaded fastener holes in composites and establish a basis for the implementation of the algorithms in commercial software.

Title:Ordnance Handling MultiAgent System (OHMAS)
Abstract:In today’s asymmetric warfare, there is a clear need to accelerate the flow of weapons from magazine to aircraft. This involves developing a semi-automated system that will significantly improve ordnance handling aboard air-capable ships. This system should prepare a Weapons Handling Plan using as much autonomy as the Weapons Department personnel are comfortable with, from collaborative software aid to near complete autonomy. 21st Century Systems, Incorporated is pleased to introduce OHMAS, “Ordnance Handling MultiAgent System.” OHMAS’s heart is the Interactive Weapons Handling Plan (IWHP), which can be thought of as equal parts of spreadsheet, map, application menu, and weapons handling scheduler and planner. The IWHP utilizes leading edge technologies and is accessible as a web service. The IWHP collaborates with other Virtual Ordnance Handling Agents (VOHA) in order to construct a weapons handling plan. Each VOHA contains a knowledge model which encapsulates the decision processes of an Ordnance Handling Officer as he constructs and executes a Weapons Handling Plan. The optimal weapon routes through the ship are determined by an innovative space-time path finding algorithm, which handles several weapons simultaneously. And with a 100th percentile commercialization rating, we are just the company to deliver this capability to the warfighter.

Title:A Novel Adaptive Intelligent Agent Framework for Agile Supply Chain Management supporting Naval Weapons Planning, Plan Repair, and Scheduling
Abstract:This document presents a computational model for problems pertaining to the planning, plan repair, and scheduling of weapons handling in aircraft carriers. This class of complex problems can be represented by a supply chain of a manufacturing enterprise with networked weapon component suppliers, factories, warehouses, quality assurance sites, and distribution centers. Through the supply chain, weapons components are acquired, transformed into weapon products, and delivered-to or returned-from customers. In the proposed framework, supply chain elements such as resources, functions, and decision-points, are represented by autonomous intelligent agents. This project will research system architectures based on a loose aggregation of intelligent agents that collectively represent an agile weapon supply chain management system. We propose the concept of groups of agents based on the biological cell paradigm. Agents form virtual organizations able to adapt constantly to changing missions. Agents will be able to learn from their past experience as well as from observing changes and corrections made by human weapon handling experts. The proposed framework is generic and can be applied without modifications to a large set of similar problems, such as stowage plan generation, load plan execution monitoring, online plan repair, inventory shipment scheduling, and warehouse offload planning.

Title:Automated, Rapid Non-Destructive Inspection (NDI) of Large Scale Composite Structures
Abstract:The manual inspection of large composite structures on Navy aircraft such as the KC- 130J wing trailing edge requires significant manpower and calendar time. This reduces the availability of assets to the warfighter and increases the life cycle cost of the aircraft. The team of Texas Research Institute, Austin Inc. (TRI/Austin), Computational Tools, and Wesdyne propose to develop robotic nondestructive inspection (NDI) techniques using ultrasonic arrays, and to design and implement a new Automated Defect Analysis (ADA) to significantly reduce the manpower required to accomplish these necessary inspections. Wesdyne’s IntraSpectTM large area robotic scanners provide the hardware platform for the solution. Combining the robotic scanner with a linear ultrasonic array provides the fastest implementation possible of the most sensitive NDI method for typical composite aerospace structures. The TRI Team will then implement a new set of Automated Defect Analysis algorithms to analyze the data as it is being acquired. The ADA will be developed as an add-on to the existing TRI Team’s NDIToolboxTM software, to be integrated into the IntraSpectTM platform and transparent to the end user.

Title:Automated, Rapid Non-Destructive Inspection (NDI) of Large Scale Composite Structures
Abstract:Composite aircraft structures present significant inspection challenges to most NDI methods. Most widely used NDI modalities, e.g. visual inspection and coin tap, have little or no relevance to composite aircraft. These are typically qualitative techniques that are difficult to replicate, and depend on subjective interpretation by the inspector. Visual inspection, which is still widely used for metal airplanes, is largely ineffective in composites, since most problems that occur leave no indication at the surface. Single point ultrasonic inspection (A-scan) is time prohibitive and its effectiveness relies on operator skill. In the proposed Phase I program, we will address the shortcomings of current thermography technology, in order to develop an automated, large scale NDI system suitable for on- aircraft inspection of large composite structures at a NAVAIR depot. The system we propose will build on the existing thermography knowledge base but, if successful, will address a significantly greater thickness range than current technology allows. It will also reduce the total cost of inspection because of substantial time savings with the added benefit of improved reliability of fidelity of depot level inspections.

Title:Novel Analytical Methods for Sandwich Core Termination Features
Abstract:Sandwich structures often offer the most structurally efficient and lowest cost solution for airframe structures. However, for sandwich panels to interface with substructure and accommodate penetrations, the core must be ramped down to a solid laminate region. Designing and verifying the structural integrity of these core termination regions is challenging due to the complexity of the physics involved and the lack of suitable design tools. In Phase I of this project, the Advatech Team will develop and demonstrate the components needed and create a proof-of-concept for a design environment for designing and analyzing the core termination regions in aero-structure sandwich panels with the intent to develop an approach for, and determine the feasibility of, global and local level analyses of core termination regions. The design environment will be structured as a modular, multi-scale and expandable tool. It will employ a modular architecture using modern software development best practices and standards. In this fashion, it will be possible in the future to replace individual modules with updated capabilities without a major software redevelopment effort. The design environment will incorporate FEMAP / NASTRAN and ESRD’s P-version StressCheck finite element codes; and eventually custom programs and applications needed to link the various modules.

Title:Novel Analytical Methods for Sandwich Core Termination Features
Abstract:The proposed project will develop a structural analysis framework incorporating high performance composite design methodologies to predict the reliability of sandwich termination features. The sandwich core termination region offers many challenges to properly design and verify its structural integrity. Complexities such as numerous interacting failure modes and sensitivity to manufacturing variations make designing and analyzing the core termination region costly and time consuming. The work proposed by VEXTEC under this SBIR project will produce a composite damage propagation prediction tool. It will explicitly link state-of-the-art laminate design techniques with the mechanistic failure models. Phase I will focus on delamination as the most significant damage mode and the mechanism will be modeled using a virtual crack closure technique (VCCT). During the Phase I Option, the global local analysis will be combined with probabilistic methods to allow for consideration of manufacturing variability throughout the structure. Phase I will show proof that structural analysis and design methodologies for bond integrity between the face sheet and the core of composite sandwich structures is readily achievable.

Abstract:Applied Physical Sciences Corp. working with L-3 Communications Maripro will develop a trawl-resistant, Robust Deployable Acoustic Node (RDAN). The RDAN technology will enable the U.S. Navy to install and operate acoustic underwater training ranges in shallow water environment to enhance fleet readiness. The acoustic sensor on the node will be specially designed to provide excellent acoustic fidelity as a tracking hydrophone while maintaining a relatively low profile to minimize risk from commercial fishing activities. The RDAN system will be deployable from vessels-of-opportunity rather than specialized cable laying ships. Commercialization within the U.S. Navy and the oil and gas industry will be pursued.

Title:Protective Technologies and Installation/Implementation Methods for Undersea Instrumentation
Abstract:The proposed project will create an innovative Trawl Resistant Tether System to protect vertically suspended, bottom-tethered types of ocean bottom sensor installations from the vulnerabilities of trawl rig damage. It uses innovative geometry and fabrication techniques that do not impact the sensor performance in any way. The proposed system addresses two specific vulnerabilities: damage to the top of the tethered float and sensor assembly caused by contact with the trawl rig leading edge or door, and damage to the tether cable as it exits the truncated pyramid trawl resistant bottom mount base. To resist damage to the tethered float and sensor assembly, the solution incorporates a protective shield that prevents it from snagging in the trawl rigging at the point of transition between the tether and the float and sensor. To eliminate the risk of damage to the tether cable as it exits the base, a pinch- and shear-proof surround at the attachment point is incorporated and prevents the tether cable from being pinched or severed by the leading edge of the trawl rig or the bottom edge of the steel door. The proposed solution for feasibility study offers sensor protection not currently addressed by trawl resistant bottom mount products.

Title:Prognostic Integrated Multi-Sensor MEMS Module (PRISM)
Abstract:Impact Technologies, in cooperation with the MicroElectronics Department at the Rochester Institute of Technology, proposes to create a single-chip MEMS multi-sensor device capable of collecting comprehensive prognostic data. By integrating many of the sensing elements required for effective prognostic life estimation within a single tiny device, the invasiveness and expense associated with implementing condition-based maintenance practices can be dramatically reduced. The proposed MEMS-based module will record temperature, humidity, vibration/shock and stress/strain data for processing via prognostic algorithms. Key tasks of this Phase I effort include: - Design and Integration of multiple MEMS sensing elements operating in close proximity aboard a single silicon chip. - Development of signal conditioning circuitry tailored for driving and recording data from the prognostic MEMS sensing system. - Optimizing power usage based on data sampling rate and duration required for each specific application. - Creating an overall package design that encompasses the sensor, electronics, and communications in form factor that can be noninvasively deployed aboard most platforms. In phase I, a prototype MEMS sensor will be fabricated and parameter sensing will be verified. This provides the groundwork for the development of a deployable, near-final-scale prototype module in Phase II.

Title:A MEMS Multi-sensor Suite for Prognostic Health Monitoring Applications in Military Systems
Abstract:The ability to monitor the health of military assets/equipment, to know their history, and to estimate their condition and/or useful life is an important issue for military planners. A key aspect of such heath monitoring (HM) concepts is a system that can sense, record, and store the history data of environmental exposures of an asset over its lifetime. Environmental parameters of most interest include temperature, relative humidity, inertial shock, and stress-strain. Such systems ideally require sensors that: are very small, utilize little power, operate in extreme environments, are maintenance free, and are low cost. Sensors with additional integrated functionalities such as data storage, and “smart” data interpretation are highly advantageous. Due to their inherent size, flexibility, and scalability advantages, Micro-Electro-Mechanical-System (MEMS) based sensor technologies are strong candidates for HM systems. An integrated MEMS multi-sensor module that can incorporate the above sensor functionalities and support data collection would help address life cycle cost and operational effectiveness issues concerning many military assets/equipment. The primary objectives of Phase I are to evaluate the feasibility (and merit) of using MEMS technologies and manufacturing processes to develop such a multi- sensor module, and provide an initial specification for a MEMS based device with appropriate capabilities.

Title:Target-Ocean Scene Simulator for the Prediction of Electromagnetic Scattering Effects of Sea on the Radar Cross Section (RCS) of Small Boats in Littor
Abstract:The objective of this proposal is to demonstrate the feasibility of generating realistic ocean-like ground planes for the RCS prediction of small vessels in both shallow and deepwater environments. Although significant progress has been made in furthering the state-of-the-art in electromagnetic modeling for air and ground environments, predicting target signatures at sea has lagged, in part, due to the problem of modeling the stochastic nature of the ocean surface. This has left analysts predicting the signatures of sea based targets, particularly in cases where shallow look down angles aren’t applicable, with the very limited and highly unsatisfactory options of using ground planes with flat or Gaussian based distributions for the modeling of sea surfaces. This proposal outlines an approach to leveraging existing technology under development at Angle Incorporated to model the ocean surface using a highly tessellated grid with a height field perturbed in real time using power spectral density models such as those defined by Pierson- Moskowitz or Hasselman. Moreover, it proposes integrating this technology into an application that also incorporates a physics engine contained in its WaveLore simulator products to model real-time vessel dynamics. With the addition of a CAD geometry import- export capability the real-world dynamic relationship between the ocean surface and the vessel orientation would be captured, providing a revolutionary improvement in predicting the radar cross section of sea-based target data.

Abstract:A comprehensive approach is proposed to providing realistic geometric models for small craft moving in a littoral environment, including representations for the sea surface, suitable for use in computing radar returns from the combined surfaces using currently available electromagnetic solvers. In the phase I effort, HyPerComp, Inc., in collaboration with Prof. Patrick Lynett of Texas A&M University, will construct and demonstrate an interface that utilizes the output of Prof. Lynett''s COULWAVE software, which generates time-dependent sea surfaces representative of both shallow and deep-water conditions, in combination with HyPerComp''s sophisticated gridding tools, to provide complete surface-patch representations for the target environment. In later phases, this interface will serve the basis for writing a GUI that will allow the end user to specify a wide range of sea and target environments for the EM solvers.

Title:Broadband, lightweight, low profile passive phased array
Abstract:The FIRST RF design combines cutting-edge technology in broadband phased array elements and high impedance metamaterials to produce a lightweight, low profile antenna array covering UHF through C-band frequencies. The array architecture minimizes the variation in gain and beamwidth over a nearly 20:1 bandwidth using a straightforward aperture architecture that avoids complex frequency-dependent excitation schemes. Wide scan volume is supported at all frequencies without grating lobes. Conventional broadband arrays use absorbing cavities to achieve a low profile and wide bandwidth, but at the cost of sacrificing antenna efficiency. The FIRST RF approach achieves efficient low frequency performance in a low profile using exciting emerging technologies in manufacturable, lightweight RF metamaterials. The techniques shrink the depth of the antenna to a small fraction of a wavelength while simultaneously mitigating interaction with the host platform and maintaining maximum efficiency. The phase 1 effort will demonstrate the critical antenna element and metamaterial technologies in small subarrays, with larger array demonstration planned for phase II.

Title:Low Frequency Ultra-Wide Band Connected Array
Abstract:Under prior efforts, FreEnt Technologies has developed a break through UWB Connected Array and then later a record breaking low frequency UWB Artificial Magnetic Conductor (AMC). The proposed effort is to integrate the new UWB AMC into the UWB Connected Array in order to achieve a new milestone in UWB array performance that achieves ALL the solicitations requirements with significant margin. The new array is expected to be highly producible and very low cost because it is made with conventional Printed Circuit Board (PCB) materials and manufacturing processes. This construction also supports a very low weight design, wherein even a vibrational ruggedized array should not weight but a few kilograms.

Title:Broadband, lightweight, low profile passive phased array
Abstract:Innovative approaches that improve overall antenna performance while minimizing antenna profile are desired solutions for all volumetrically restricted platforms. This is especially critical for advanced intelligence, surveillance, and reconnaissance (ISR) platforms that are expected to provide extended time on station. Spectra Research proposes an innovative approach to accomplishing the program objectives by employing advances in fragmented aperture antenna designs, in concert with the extensive Spectra Research capability in designing specialized antennas, to develop solutions for a unique ultra broadband phased array. Both Cartesian and cylindrical FDTD simulations will provide a set of design rules that then may be used to modify analytical approximations. Once this is done, the design rules will be applied to intelligently optimize a candidate antenna design in the presence of specialized materials. In Phase II of this program, an advanced antenna design will be implemented based on lessons learned and sponsor guidance and a prototype demonstration will be constructed and measured.

Title:Multi-Sensor Automated Ship and Small Craft Classification Tools
Abstract:The current state of the art in assisted target recognition separately processes individual image frames from different sensor modalities (e.g., ISAR and EO/IR) and forms a decision based on a weighted sum of classification confidence for each modality. The request for proposal (RFP) indicates that it is desirable to investigate the potential benefit of simultaneous processing of ISAR and EO/IR with the intent of using the EO/IR data to improve the focusing of the ISAR imagery on a frame-by-frame basis. While this approach may yield improved tracking of the scatterer field for improved focusing and hence improved classification/recognition, it is possible that more robust and relatively better focusing performance could be obtained through signal processing techniques that exploit radar transmit-receive (Tx-Rx) phase center diversity. In contrast, exploitation of radar Tx-Rx phase center diversity would not require EO/IR imagery (or for that matter any other sensor data) to be needed for improved ISAR focusing.

Title:Advanced Real-Time Imagery Fusion for Targeting and Mission Planning Using Volumetric Display
Abstract:The US Navy seeks innovative capabilities for the accurate and efficient volumetric display of geospatial data in real-time on a small form factor to support feature extraction for targeting in forward deployed environments. To meet this requirement, IAVO Research and Scientific proposes the development of the GeoMRSV (Geospatial MultiResolution Scene Visualization) suite. GeoMSRV will provide a highly innovative, fundamentally sound, low risk solution for rapidly ingesting, displaying volumetrically and extracting features from multiresolution, multisensor geospatial data that may be manifested in a small form factor hardware solution such as a ruggedized laptop. The underlying photogrammetric capabilities of GeoMRSV set it apart from traditional existing and emerging solutions supporting the rapid integration of new sensors and real-time update of newly acquired sensor data. GeoMRSV will leverage existing state of the art GPU protocols to enhance plug-and-play technologies to support holographic, pseudo- holographic, and other emerging display capabilities.

Title:Advanced Real-Time Imagery Fusion for Targeting and Mission Planning Using Volumetric Display
Abstract:MNB Technologies presents a novel approach to integrating mission-specialized adaptive knowledge fusion front-end systems to their unique hardware accelerated real time synthetic holography visualization engine and projector. The result of this will be a portable distributed system that may be used to integrate disparate information into a cohesive volumetric perspective of the battlespace from sea floor to low earth orbit. Of particular significance is the system’s ability to extract highly accurate target mensuration and mission planning knowledge from real-time data sources using a holographic display with “reach in” human interface. Unlike approaches that demand new information schema to work, the proposed system is intended to uptake information from existing sources and integrate it, on demand, into actionable knowledge presented holographically. The system is highly scalable and may be used with wearable, notebook, and desktop class human interface systems connected to hand-held, tripod-mount, or fixed-mount projectors. Further, the system will find beneficial use in non-defense application areas including: medical imaging, education, air traffic control, drug discovery, homeland security, scientific visualization, and entertainment.

Abstract:To address the Navy’s need for an innovative volumetric visualization technology using a real-time 3D display within a laptop environment, Physical Optics Corporation (POC) proposes to develop a new real-time Holographic Volume Multiplex 3D (HOLOVOX-3D) volumetric visualization system based on high-speed projection of volume cross-sectional image planes using a novel multiplexed holographic screen. The innovative use of free- space volume image integration via hybrid electronic image processing, with optical image fusion allows the system to operate in real-time within a laptop environment, and also allows use of an interactive interface such as hand, dataglove, or wand to extract 3D spatial data from the displayed volumetric image. The system provides full-parallax volumetric 3D imagery with minimal electronic processing of 2D, stereo 2D, 3D, and computer-generated synthetic imagery, and optical image fusion by projection of multiperspective images into a common volumetric 3D space, which directly addresses the Navy’s requirements for targeting and mission planning. In Phase I, POC will demonstrate the feasibility of HOLOVOX-3D system by design, simulation, and experimental demonstration of key performance by integrating a laboratory breadboard prototype. In Phase II, POC plans to design, develop, and demonstrate a fully functional prototype system to the Navy.

Title:Analog to Information (A2I) Sensing for Software Defined Receivers
Abstract:ELINT systems are often limited in bandwidth because the Nyquist criterion restricts the sampled bandwidth to one half of the maximum sampling rate of the A/D converter. While A/D converter technology has improved over the last several years, it is still not sufficient for many wideband applications. Compressive sensing (CS) is a revolutionary concept recently proposed that allows for wider bandwidths to be processed using sampling rates less than the Nyquist rate when the sampled signals are sparse. Radar signals, such as those detected by an ELINT receiver typically meet such requirements for sparseness. GIRD Systems proposes herein a novel new compressive sensing method that is optimized for ELINT receivers that detect radar signals. By selecting an appropriate basis function set, we can deliver a system that meets performance expectations while still capable of being implemented in hardware.

Title:Analog to Information (A2I) Sensing for Software Defined Receivers
Abstract:Propagation Research Associates, Inc., (PRA) proposes to design a receiver that will significantly reduce the sample rate required for a pulsed-Doppler EW sensing application using Compressive Sensing (CS) technology. The PRA Adaptive CS receiver will provide a compression in information space that will be sufficient to characterize multiple pulsed- Doppler waveforms accurately over a relatively large frequency band of interest. A pulsed-Doppler waveform can generally be characterized by a few parameters such as signal frequency, pulse width, pulse repetition frequency, dwell time, and bandwidth. The CS receiver will sample a number of channels (8) at the information rate required to determine the waveform parameters of interest instead of the Nyquist rate. By sampling at the information rate, the Analog-to-Digital Converter sample rates will be reduced by a factor of 50 to 1. An additional signal reconstruction channel (9th channel) will designed that can adapt to the output of the CS receiver to minimize the ADC sample rate. PRA will simulate the CS receiver and demonstrate its capability to (1) characterize pulsed-Doppler waveforms with varying pulse parameters, and (2) reconstruct the signal with minimal ADC sampling.

Title:Analog to Information (A2I) Sensing for Software Defined Receivers
Abstract:Radar Warning Receivers (RWRs) are an integral part of Tactical Aircraft Protection Systems and are used to quickly detect imminent threats so that countermeasures or other actions can be used to avoid attack. Threat Radar signals include pulsed Doppler signals with typical carrier frequencies from 2-40 GHz with the possibility to extend to even higher. An ideal RWR would be one based on the concept of a Software Defined Receiver (SDR), in which all key receiver algorithms are implemented in some form of programmable device. However, a significant limitation of a SDR based RWR is that the received RF signal must be sampled with an A/D converter which limits the usable bandwidth of a SDR to roughly 2 GHz. The relatively new field of compressive sensing is based on the notion that the information content of a signal may be much less than its instantaneous bandwidth, and that this signal “sparseness” can be exploited directly during the sensing operation. When applied to the sampling of wideband Radar signals, compressive sensing can allow Radar signals to be sampled well below the Nyquist rate, allowing COTS ADC devices to be used as a front end to a flexible software defined Radar Warning Receiver. This Phase 1 program will extend compressive sampling to the area of signal parameter estimation in order to detect and parameterize unknown received Radar signals over the entire Radar bandwidth from 1-100 GHz with a single ADC front- end receiver.

Abstract:In support of the Naval Air Anti-Submarine Warfare (ASW) Systems'' mission to rapidly deploy portable, autonomous sensor systems for training ranges in threat representative locale, NanoSonic offers Piezo-Rubber™, maritime power harvesting transducers. Piezo- Rubber™ distributed skins would exploit the natural energy sources from the sea (light, salinity gradients and water movements) to generate electricity. The unique, low mass density, shape changing transducers may eliminate the need for finite, battery powered sensors and lengthy cables. As NanoSonic has recently demonstrated Shape Memory- Metal Rubber™, EMI shielding (-88dB), flexible, adaptive materials that can morph underwater; the Piezo Rubber™ skins offer dual-use technology as self-powered underwater, or near surface and at surface unmanned vehicles. The Piezo-Rubber™ self-powered morphing skins would be tested at sea in sensor systems and within a line of bio-mimicking naval platforms which will require the strength, flexibility, and ability to embed sensors within a realistic skin-like enclosure. Materials evaluation shall be carried out with our defense prime partner to verify the feasibility to sustain 10-1000 Watts of power for 30 days to 1 year during Phase I-II to increase the TRL from 4-8. TRL9 shall be reached when Piezo-Rubber™ transducers operate at water depths ranging from 100- 5000 feet for 2-20 years.

Title:Power Harvesting Systems for Use with In-water Instrumentation
Abstract:Energy harnessing technology must be tuned to the environment that they harness. The ocean harnesses energy created by the sun storing most of it in the surface in the form of heat, light, and kinetic energy. The deeper in the ocean you travel, your options become reduced. Near the ocean floor there is essentially only one viable source still present besides biological energy. It is kinetic energy in the form of a small slow moving current that changes direction. Typically, the current will be 0.25 m/s. Turbines are unrealistic due to bio-growth and the small amount of power available. A solution presents itself in the form of vibrations created by vortex shedding. On the freeway in older model vehicles, an antenna will start to move side to side and back and forth violently at certain speeds. This is when a long cylinder reaches its intrinsic resonant frequency. Take this antenna, and instead of suppressing this effect, we maximize it, tune it, and mount it onto a circular rigid base plate sandwiching numerous, specially designed piezoelectric vibration harnessing generators. You now have a system that can capture slow moving current energy from any direction, for the use of sea floor transducers.

Title:Single Crystal Transducer Technology for Undersea Tracking Ranges
Abstract:Undersea tracking ranges are used to monitor and assess the performance of submarines, torpedoes, ships and targets conducting tests and exercises on weapon system performance. The ability to track these platforms is largely based on the performance of the transducers used in the tracking systems. Current state-of-the-art piezoelectric ceramic (PZT) transducers have performance limitations; therefore this SBIR will investigate the use of newly developed transducer material, lead magnesium niobate- lead titanate (PMN-PT), commonly known as single crystal, to provide desired tracking range performance enhancements. The improved electromechanical coupling factors, dielectric constant, and loss tangent associated with PMN-PT material will provide improved transducer response. These improvements include increased bandwidth and source level capability and operational depth for the projector elements, as well as enhanced sensitivity and improved self noise for the hydrophone system. The proposed program will model transducers using this material to establish a baseline approach, fabricate a prototype transducer and perform in-water testing to establish performance enhancements relative to PZT material. LewTech has formed a strong team with UnderSea Sensor Systems, Inc., a major manufacturer of sonar systems, surveillance systems and sonobuoys, to support the design and development of practical, cost effective transducers utilizing single crystal material.

Title:Safe, High-Power Battery for Sonobuoys
Abstract:• The Navy has established a need to update the present high power sonobuoy power source used in Air Anti Submarine Warfare (ASW) Systems. Present technology for the ASW sonobuoy battery utilizes a primary Lithium/SO2 battery chemistry which is capable of providing 20, 10 second pulses drawing 5500 W of power at 65 V. The existing system offers a low cost, high power solution, however concerns have been raised over the safety of this chemistry. Under high rates of discharge, the SO2 cell generates excessive amounts of heat which cause the cells to vent, releasing toxic fumes to the surroundings. MaxPower offers a baseline Li/MnO2 cell system as replacement for the Li/ SO2. Unique in this baseline cell are the cathode formulation and superior solution properties that can sustain high discharge condition. We showed equivalent pulse data showing that the Li/MnO2 cell system can meet the established power requirements, and we will validate this capability at the full size cell hardware level.

Title:An Innovative In-Flight Refueling Probe Component that Eliminates Accidental Overload of the Mast Assemble During Air Refueling
Abstract:gggGiven the U.S. Navy’s goal to eliminate the potential loss of an F-35/Joint Strike Fighter aircraft during in-flight refueling operations it is desirable to modify today’s probe and drogue system that is based on a “weak link” design. Refueling hose-whip is a long standing problem that leads to stress overloading of refueling components, which in turn break off leading to catastrophic Foreign Object Damage (FOD) to the single fighter engine. In response to this potential danger of losing the engine, Design By Analysis, Inc. (DBA) of New Britain, Connecticut, proposes to develop a detailed understanding of the physics of hose-whip and use it, together with newly available nanotechnology, to engineer a novel, robust probe concept that can be quickly developed and introduced into the field as a finished product. DBA is a developer of innovative fuel delivery systems, with extensive experience in the design, analysis and testing of flight mechanical components. DBA calls this new probe a Reliable Energy Absorbing Probe (REAPTM) to highlight the key features it intends to incorporate into this design. Namely, the REAPTM probe will provide both flexibility and energy dissipation to dampen system response to protect against overload forces from hose whip.

Title:An Innovative In-Flight Refueling Probe Component that Eliminates Accidental Overload of the Mast Assemble During Air Refueling
Abstract:A flexible hose and drogue system typically employed in military aircraft refueling operations has proven reliable except when excessive shear forces on the receiving aircraft’s refueling probe are induced, which can induce a break-away design feature. New concepts are required to eliminate this break-away feature, reducing FOD and potential damage to the aircraft. This requires a new innovative probe design that can withstand high loads and will not break-away, resulting from utilization of a high strength and flexible attachment mechanism. Innovative concepts may include flexible linkages, active control devices or other attachment mechanisms that can absorb the loads on the probe relative to the drogue. Phase I will develop refueling simulation models of the flexible hose and drogue with the receiving aircraft’s refueling probe to predict the induced loads relative to specified operational parameters. The simulation models will be based on existing cable-body dynamic analysis software and a 6 DoF aircraft model in an integrated simulation. Design concepts will then be developed and examined in a number of parametric studies for typical operational scenarios to demonstrate the design feasibility. One or two of the most promising concepts will be down-selected for consideration in Phase II prototype development and testing.

An innovative heat exchanger concept has been identified, which can reduce system weight and volume to below 100 lbs and 8 cubic feet, respectively, while also reducing pressure drop and cost. Under the proposed project, the innovative heat exchanger technology will be analyzed, developed and tested, to prove performance. In addition, the complete thermal management system, which incorporates this heat exchanger, will be analyzed to show that steady and transient system performance meet Navy requirements, and that costs are reduced, versus conventional approaches.

Title:Thermal Management System for Tactical Airborne High Power Laser Applications
Abstract:An efficient, compact, and lightweight thermal management system (TMS) is needed to enable integration of a 30kW solid-state high-energy laser (SSHEL) system into tactical airborne applications. Ultimately, the TMS should be less than the final design target of 100 lbs and 8 ft3 in volume. Inherent limitations to state-of-the-art technologies must be overcome to meet program goals. Aspen Systems proposes to develop one of two promising system design concepts presented in this proposal. One system (JP5 Concept) transfers heat from a water/glycol-based liquid loop which cools the laser to a jet fuel (JP-5) through a high-performance liquid-to-liquid heat exchanger (HX) which is also very lightweight and compact. This high-performance HX and system is enabled by microchannel surface enhancement geometries which increase thermal transport mechanisms between the fluid and heat exchanger surface material. The other system (Radiator Concept) transfers heat from a water/glycol-based liquid loop which cools the laser to ambient air by means of a high-performance liquid-to-air heat exchanger (HX). However, due to the inherent limitations of the thermal transport properties of air, the HX and air fan/motor contributes to a system which also achieves a weight and size less than final program targets, but to a lesser degree.

Title:Development of a Thermal Management System for Tactical Airborne High Power Laser Applications
Abstract:Current aircraft thermal management systems are not capable of dissipating high-heat- flux thermal loads or transporting and rejecting overall thermal loads on the order of those associated with tactical lasers. Beyond overcoming limitations of existing systems, the developmental system must meet strict volume, mass, and reliability requirements associated with aircraft operation. In Phase I, Mainstream will complete both an analytical evaluation of candidate high-heat-flux cooling technologies and system architectures for an airborne tactical fiber laser system as well as an experimental evaluation of a sub- scale thermal management system. During the Phase I option, Mainstream will design the complete full-scale fiber laser thermal management system in order to accelerate the timeline to testing a working full-scale system in Phase II. This ambitious effort will be made possible by leveraging Mainstream’s extensive experience and background in advanced thermal management and heat transfer.

Title:Universal Signal Matching for RF Threat Classification
Abstract:In response to Navy SBIR Topic NAVY 09-113, “Universal Signal Matching for RF Threat Classification,” Michigan Aerospace Corporation proposes a robust method to identify emitter Electronic Intelligence Notation types from sensor data streams based on state-of- the-art techniques in estimation and detection for radar signatures developed in the arena of Signals Intelligence for Specific Emitter Identification. Our approach combines advanced time-frequency analysis to generate feature vectors for individual pulses, with cluster analysis for de-interleaving. This provides the basis for identifying the frequency agility of pulses as well as the PRI agility of the radars. These features are then compared to a library using Ensembles of Decision Trees, which provide robust classification as well as known/unknown detection. The feature vectors of newly discovered emitters are added to the library and additional examples of previously-known emitters are added to supplement description of the higher-order statistics of the clusters of these emitters in feature space. RF data streams from observational platforms often contain instances of several emitters, multi-path artifacts, and receiver coloration. It is possible to obtain concurrent streams from multiple platforms. In this situation, we employ a technique like Blind Equalization Source Recovery to recover undistorted transmitted pulses from the plurality of sensors.

Title:Universal Signal Matching for RF Threat Classification
Abstract:The U.S. Navy uses digital wideband electronic warfare (EW) receivers for RF threat warning and cueing of countermeasures to protect Navy aircraft. The receivers accomplish these functions by processing RF waveforms from enemy radars, extracting pulse parameters, and conducting emitter identification. The receiver''s ability to accurately identify the emitter type (necessary for warning and countermeasure cueing) depends completely on its ability to form accurate parameter estimates from waveform pulse trains. In particular, the radio frequency (RF) and pulse width (PW) parameters are typically measured directly, but the pulse repetition interval (PRI) must be derived based on the output of a deinterleaving algorithm. This algorithm searches through the pulse input buffer associating pulses together using a variety of matching techniques. Missing pulses, receiver blanking, and mis-associations can cause the PRI estimate produced by the deinterleaver to be incorrect. Corruption of the PRI estimate is the primary source of the emitter identification problems. To deal with emitter identification issues, Navy EW engineers modify the emitter identification (EID) table that is used with EW receivers to accommodate known failure modes of the deinterleaving algorithm. However, doing so increases work load and leads to sub-optimal receiver performance in certain conditions. To mitigate the need for human intervention, a new approach is needed for EW receiver processing. The objective of this project is to develop a new corrupted pulse train resolution algorithm that will process the data produced by the deinterleaving algorithm and attempt to identify corruptions in the pulse train data that could lead to an incorrect identification. In taking this approach, knowledge of the scenarios that cause corrupted pulse trains to be generated by the deinterleaver can be embedded in the algorithm instead of being encoded in the EID table. Thus, the receiver will be able to maintain a universal table, and the need for adapting the EID table to specific missions will be mitigated.

Title:Universal Signal Matching for RF Threat Classification
Abstract:This effort investigates and assesses the feasibility of new robust dynamic methods to classify threats from received RF signals for application across a variety of sensors and platforms using new information that can now be obtained from modern digital EW receivers. Mathematical and statistically based techniques including covariance functions, autocorrelation and kurtosis to automatically characterize additional emitter characteristics proposed will be justified. Classification includes classic parameters (RF, PW, PRI) and new automatic statistical processes for scan, PRI and RF Agile typing and characterization. New descriptors for Waveform Function (e.g. Track, Search) and Type (e.g. Pulse Doppler, FMCW) will be developed to automatically assess waveform intent for improved situation awareness, support EA, and improve ID. Intentional Modulation on Pulse (IMOP) Type and Characteristics are incorporated into emitter track / correlation using FPGA based IMOP results from a prior Phase II/III SBIR. The processes will be integrated into existing multi-hypothesis Bayesian belief network enabled tracking, classification and identification MATLAB processes (C/C++ for real-time). Established metrics of effectiveness are used to characterize performance. Proof of concept MATLAB code will be demonstrated with signals from RAS’ suite of synthetic signals, real-world modern stressing radar digitized data (unclassified), and PRI and Scan Pattern generation tools.

Abstract:Advanced Coherent Technologies, LLC (ACT) has demonstrated the value of simple Visible-Near Infrared (VNIR) EO multispectral system in small packages in recent US Navy sponsored Small Business Innovative Research (SBIR) programs (N06-013, N05-119 and N07-019) as well as in the current Multimission Advanced Sensor System (MASS) project which is focused on deploying a VNIR multispectral sensor on the TigerShark UAV for NAVIAR 4.5.x. The sensor system being developed for Whale Search Radar (SBIR N07- 019) will consist of three VNIR mulitispectral cameras, one Sony block zoom video camera and one LWIR microbolometer. The cameras are integrated into a modified CloudCap T2 turret (7 lbs). The success of these programs provide an excellent launching point to satisfy the current SBIR topic. The ACT team plans to leverage the progress made in current VNIR MSI programs and will focus both on miniaturizing the system for deployment in UAV’s (replacing the current single board computer used for processing with a field programmable gate array based system for example) and on tailoring the system for JMMES applications. It is the objective of this project to incorporate as much of the multimission capability available in the JMMES system into the Tier II UAV payload package.

Title:SiC/SiC Composites with Multiple Concepts to Reduce Foreign-Object-Damage
Abstract:Existing SiC/SiC composites have shown inferior resistance to foreign-object-damage (FOD) which limits the applications of SiC/SiC composites high potential to reduce weight and increase specific power in gas turbine engines. There are a number of concepts that individually may only minorly increase the resistance to FOD, but when combined in one composite become additive and possibly synergistic to increase FOD resistance that enables SiC/SiC composites to be utilized in areas sensitive to FOD. This program will define several individual concepts that reduce FOD to SiC/SiC composites through confirmed testing, and demonstrate combining the individual concepts to produce a SiC/SiC composite which substantially eliminates FOD as a design limitation. Composite specimens will be delivered to the Navy, further optimized in the option, and transition into Phase II for testing in a platform with an OEM.

Abstract:MR&D is proposing to perform a combined analytical, fabrication, and experimental program to achieve the program objectives of developing innovative approaches to improving FOD resistance of CMC materials, specifically GE’s HyPerCompTM SiC/SiC CMC material. MR&D will develop finite element math models of the CMC material specimens and the high velocity metal projectiles to simulate impact testing. The models will first be verified by reproducing experimental data measured on impacted CMC specimens. Candidate methods for potential improvements to the FOD resistance to the HyPerCompTM CMC material will be analytically investigated, through mathematical simulations of impact tests. Manufacturable methods which have analytically demonstrated promise in mitigating impact damage will then be fabricated by CCP and experimentally evaluated through impact testing.

Title:Innovative Approaches to Develop Foreign-Object-Damage (FOD) Tolerant Coatings for Ceramic Matrix Composites (CMCs)
Abstract:CMCs are currently being considered and used for aeroengine airfoil applications with a goal of increased specific power. Of a particular concern of CMCs regarding of life- limiting degradations is impact damage by small foreign objects. Fracture toughness and hardness have been the dominant material properties for determining the foreign objective damage (FOD). A material with both high hardness and high fracture toughness would be expected to have better FOD tolerance. Ceramics are promising for impact resistant coating (IRC) to alleviate the FOD due to their high hardness and high fracture strength. However, their fracture toughnesses are not sufficiently high to fully utilize such useful properties. Such problems can be solved by applying the UES composite coating technology. The composite coatings are remarkably tough, strong, hard, and readily coated, and that seems to meet the needed material properties. The goal of the Phase I program will be both demonstration of technical feasibility and development of tough, strong, and hard coating on commercial SiCf-SiC composites, in order for alleviating the FOD. Subsequently, muti-functional all-in-one coating system that can realize both FOD tolerance and oxidation resistance, will be developed during the Phase II program.

Abstract:The overall objective is to develop new technologies to optimize the design of electrically small, broadband antenna arrays for communication, electronic support, and radar systems. The critical elements to be investigated are individual broadband (multiple octave) radiator design, optimal integration into an array where strong mutual coupling is present, and intelligent impedance matching to ensure the delivery of maximum power between the radiator and transceiver, helping to improve the overall efficiency of the array. We propose a time domain analysis and design technique for arbitrary shaped conducting structures using associated Laguerre polynomials for analysis and synthesis of broadband electrically small antenna arrays.

Title:Optimized Corrosion Resistant Bearing and Gear Steel Thermal Processing
Abstract:Pyrowear® 675 is noted as a high performance bearing material used in turbine engine and other higher temperature applications. The mechanical properties and stability necessary for these applications is achieved via carburizing by design. The carbides that form to provide the hot hardness and desired mechanical properties for bearing service are at the expense of corrosion resistance. As the carbides form during carburizing, the alloying elements responsible for much of the corrosion resistance are removed from solution. When the alloying elements are tied up in carbide phases, the corrosion protection is drastically reduced. With the current thermal processing methods, the corrosion protection cannot be maintained when the hardness requirements are met. IBC Materials and Technologies will develop innovative thermal processing technologies based on solution nitriding and a vacuum carburizing with post-low temperature ion plasma nitrocarburizing. This solution will achieve an expanded S-phase austenite (S- phase) in the Pyrowear® 675, leading to superior hardness and corrosion resistance of the bearings and gears.

Title:Optimized Corrosion Resistant Bearing and Gear Steel Thermal Processing
Abstract:New, patented highly advanced thermo-chemical processing (LINTERPROCESS™) and heat-treatment (LINHEAT™) technologies, presented in this proposal, were developed by SANOVA to address and solve metal and alloy performance issues described in this SBIR. Based on these innovative technologies, SANOVA will design treatment process which creates highly durable protective surface layers on components made from Pyrowear® 675 alloy with superior corrosion resistance and other strong mechanical properties. Pyrowear® 675 is one of the more promising relatively new materials being studied for use in bearing and gear manufacturing. But achieving adequate corrosion resistance on the surface of this alloy, while maintaining required mechanical properties and microstructure, proved to be a formidable challenge for traditional heat-treatment technologies. SANOVA’s LINTERPROCESS™ and LINHEAT™ technologies have a distinct advantage over traditional furnace-based treatment processes due to combination of specially generated and applied highly effective active media and precise control of treatment parameters, and are able to produce desired mechanical performance, microstructure and compression stresses of Pyrowear® 675 surface layer, while keeping chromium levels adequate to exhibit strong corrosion resistance. LINTERPROCESS™ and LINHEAT™ technologies are unique and offer important performance advantages and cost savings over traditional heat-treatment technologies. They produce highest-quality results in shortest treatment durations.

Abstract:Impact Technologies, LLC, in cooperation with American Fujikura LTD/ Noyes (AFL Noyes), propose to develop a hand-held fiber optic connector inspection system that provides a “GO / NO-GO” result based on automatic determination of the terminus endface cleanliness, workmanship, and health. This teaming brings together the research expertise of Impact technology in health monitoring, and embedded data collection with the deep manufacturing knowledge and leadership in hand-held fiber optic inspection from AFL Noyes. Thus a seamless integration from research to market transition is expected. The problem of ambiguity in conventional inspection systems, lack of decision recording, complex and conflicting specification, and challenging test application, are investigated and matched with modern technologies to radically improve the inspection operator’s process and decision-making criteria. A simple, compact, and intelligent “GO/ NO-GO” system is proposed that leverages existing form factors as well as the state of the art in fiber optic probe sets, CMOS technologies, and image processing algorithms to provide the operator with firm decision-making capability as well as the flexibility needed for field and avionic application—specifically JSF. Of significance, this proposal has a high innovation and transition opportunity for commercialization, as AFL/Noyes is a dominant supplier of fiber optic test equipment to the communication industry.

Title:Fiber Optic Connector Inspection Test Set
Abstract:The endface of an optical connector must be precisely manufactured and well maintained to ensure reliable optical signal performance throughout its life. Harsh environments of military applications expose a connector to conditions that greatly increase the possibility for damage or contamination. We propose the development of a comprehensive, simple and robust testing instrument to objectively evaluate the complete health of existing pin and socket fiber optic termini at the site of installation. Phase I will explore the feasibility of integrating advanced micro-optical phase measuring functionality into a handheld imaging probe. The instrument will generate an enhanced data set of both visual and 3D information about connector endface parameters and produce a clear Go/No-Go evaluation. Connector health assessment will consider defects, contaminants as well as connector endface geometry parameters. PROMET is an excellent candidate for this project because of the extensive experience gained from the development of the FiBO line of interferometer products as well as optical instruments for various military applications. A hand-held interferometric probe would complement PROMET’s FiBO line of fiber optic testing products and could be quickly and efficiently commercialized through its existing distributor network to customers in the defense, aviation and commercial sectors.

Abstract:We propose to develop a power scalable, multi-spectral, fiber laser source, capable of simultaneous laser ourput in the mid-IR (2-5um) atmospheric propagation bands of interest. The fiber laser is based on non-silica oxide fibers being developed by Fibertek and its partners, and is optimized for both low loss in the mid-IR region, as well as for high non-linearity. This all-fiber architecture with multi-spectral laser output is enabled by directly writing multiple fiber Bragg gratings (FBG) in such mid-IR fibers, via femtosecond laser micromachining.

Title:High Average Power Superconituum in the Mid-Infrared
Abstract:Infrared countermeasure (IRCM) systems defend many aircraft and ground vehicles located in combat zones from infrared-guided attacking missiles. These systems disable the incoming threat through the use of directed infrared laser energy. To protect from various heat-seeking missile threats, Multiple-band coverage is required in the infrared region (1-5 micron). Currently available IRCM solutions are very expensive and suffer limitations and disadvantages such as excessive size and weight; long initial cool-down time (cryogenic temperatures), short operating time, limited duty cycle, complex packaging, low wall plug efficiency, poor beam quality, and limited output power. The proposed work will develop an innovative compact chalcogenide fiber-based broadband (1-5 microns) high average power (5-10 Watt) source using supercontinuum generation. The feasibility of generating supercontinuum in novel chalcogenide nonlinear fiber will be studied. Phase I activities will include theoretical modeling and design for the nonlinear fiber and supercontinuum generation. A prototype fiber will be delivered.

Abstract:NP Photonics proposes to develop a supercontinuum (SC) fiber laser with the capability to propagate a multi-spectral laser beam with 10 Watts of time-averaged power. This program focuses on all fiber optic approach with particular emphasis on covering the mid- IR portion of the electromagnetic spectrum.

Title:Inverse Autofrettage for Titanium Hydraulic Tubing
Abstract:“Inverse Autofrettage” is an adaptation of the century old autofrettage method used to generate residual compressive stresses at the inner surface of thick walled tubes like cannon barrels. It relies upon briefly exposing formed hydraulic tubing (which is thin wall, in this case) to very high hydrostatic pressure in a specific manner that results in large residual hoop compression strain. With inverse autofrettage the entire wall thickness of the tube is prestrained, not just the inner bore surface. This prestrain reduces the operating hoop tensile stress in the tube under hydraulic pressure, significantly increasing fatigue life and reducing propagation rate of surface flaws such as scratches. In Phase I the process is optimized both analytically and through process trials on ¼” tubing. Tube sections are treated to various residual strain levels, and these strains measured by X- ray diffraction. Tube specimens are then impulse pressure fatigue tested at 5,000 psi, with and without a series of carefully controlled, laser generated surface notches to generate fatigue life curves. In the Option, similar work is performed with formed (curved) tubing sections. Substantial improvements in cycle life and flaw tolerance are anticipated, and several commercialization partners have expressed interest in the process.

Title:Cavitation Peening of Hydraulic Tubes for Fatigue Improvement
Abstract:In order to reduce weight and improve performance, many new aircraft designs are using titanium hydraulic tubing because of it’s high strength to weight ratio and high pressure rating. Higher hydraulic pressures enable the use of small and lighter actuators, allowing further reductions in weight. A modern performance rotorcraft, such as the V-22 or the new CH-53K, can have as many as 500 hydraulic tubes, so low weight tubing becomes a critical requirement. However, the titanium hydraulic tubing has proved to be sensitive to very small surface flaws in lab tests. Scratches as shallow as 0.004” have been shown to cause failure in less than 50,000 cycles in the lab – or as little as 40 flight hours! The cavitation peening technology proposed in this project would make the tubing more robust and forgiving of flaws by inducing residual compressive stresses that are deeper than the anticipated flaws. Preliminary tests have demonstrated the process can dramatically increase notched fatigue life by more than 20 times at a projected cost of less than $50 per tube. The proposed project will build on the initial testing to demonstrate feasibility to the Primes and other stakeholders.

Information collected and reasoned by these instruments will provide a basis for Real- Time Publish-Subscribe (RTPS) of combined application data and system events to form a cohesive runtime consolidated-view for remote listeners (data subscribers) that supports RM monitoring and management functions. Additionally, the proposed adjoining tools will enable off-line analysis of collected data and events as well as playback capabilities of “interesting” RM episodes so that Complex Event Processing (CEP) techniques can be applied in order to devise improvements on RM plans for subsequent system operations. This will be an initial step toward adaptive RM for distributed real-time systems.

Title:Minimally Intrusive Real-time Software Instrumentation Technologies
Abstract:Real-Time Innovations (RTI) proposes to build a new architecture for non-intrusive instrumentation for distributed real-time systems. With this design, developers will directly see and record key internal application data, dynamically monitor network and process statistics, and analyze system operational performance – all in real time. We will support direct code instrumentation, run-time patching, operating-system statistical collection, and integration with post-processing tools. Our goal is to provide visibility into all important system data, in real-time, with minimal developer effort. The data will be integrated and collected with OMG Data-Distribution Service (DDS) middleware, allowing immediate application to most of the Navy’s active software development programs. This network integration will also make the toolset capable of network-wide analysis of a distributed system. As both the world’s leading vendor of DDS middleware and the developer of the most successful real-time tool suite, RTI is uniquely qualified to deliver and support this critical functionality. We will collaborate with key customers, including NSWC-DD, SPAWAR, Raytheon (DDG-1000), and Lockheed Martin MS2 (Aegis) to ensure applicability to Naval systems. We will commercialize the results, and offer it as a COTS product to our over-300 current and all future customers.

Title:New Generation Gas Turbine for Small Boat Propulsion
Abstract:The next generation of riverine craft and naval unmanned surface vehicles will require more capability, including higher payload and volume needed to carry more troops and their equipment, increased ballistic protection, more weapons, and additional mission equipment. In order to meet system integration requirements and maintain the maneuverability and agility required for survivability, these craft must be kept near the weight of current craft, while still attaining the required mission range and capability. Because the propulsion system is such a high percentage of the overall weight, it is considered to be a high payoff candidate for weight reduction initiatives. Candent Technologies is developing a new generation of small gas turbine engines which are particularly applicable to small riverine craft. This new generation of highly efficient turbine engines retains the light weight and small size characteristic of gas turbines, but their fuel consumption is close to that of a diesel engine. This low cost engine is based on the Proof of Concept prototype designed, built, and tested by Candent Technologies under contract to the US Army. The proposed engine will provide substantial weight savings and improved performance for the next generation of riverine craft.

Title:Advanced Marine Engine for Combatant Craft Increased Payload
Abstract:Today’s riverine forces employ combatant patrol/assault craft that rely on speed, acceleration, and maneuverability for survivability and multi-mission success. These capabilities are at risk because of the increasing demand to carry more extensive payloads. Current diesel fuel propulsion systems are typically modifications of truck or industrial engines with a weight to power ratio of 3-5. By reducing the propulsion weight, the craft will be able carry more extensive payloads. The three engine choices are diesel, gasoline, and turbine. Current diesel engines don’t meet the weight goal. Gasoline engines are not an option due to fleet requirements. Turbine engines have an unacceptable thermal signature. However, a novel engine, the Linear Power Transmission (LPT) engine has the greatest potential to meet the 1lb/hp goal. The original engine, by Herrmann, which received FAA certification in the 1950’s, weighed 237 lbs and produced 200 hp. This proposal seeks to demonstrate the feasibility of an innovative multi-fuel marine engine, based on the LPT, we currently produce. Project goals include an engine design that is scalable or can be modularized, 100-700Hp range for direct drive systems, weight-to-power ratio less than or equal to 1.0, and able to withstand marine operational duty cycles with extended life cycle.

Title:Advanced Marine Engine for Combatant Craft Increased Payload
Abstract:Speed, acceleration, and maneuverability of today’s combatant patrol and assault crafts are critical capabilities to the riverine’s survivability and mission success. The demand for constant increase in payloads jeopardized these capabilities due to increase in craft weight. The current diesel fuel propulsion systems are typically large and heavy with weight-to-power ratios in the 3 to 5 range because they are mostly designed for heavy truck and land-based power generation. In addition, the reliability and life span of these propulsion systems suffer because the duty cycle of a marine combatant craft is different than that of the land-based applications. As a result, a new innovative multi-fuel power plant has been proposed to achieve a weight-to-power ratio of 1 reliably. This engine was designed based on (1) over 30 years of successful racing engines design and development experience, (2) extensive use of race-proven high specific strength materials, (3) rotary valve variable valve timing concept, (4) parasitic losses reduction through minimizing friction and pumping losses, (5) modular engine architecture for different displacement to suit a variety of applications, (6) advanced engine calibration to optimize engine performance depending on the combustion characteristics of each fuel, and (7) Optional-innovative dynamic compression ratio variation.

Title:Marine Inter Turbine Burner Equiped Turboshaft Engine for Combatant Craft Increased Payload
Abstract:Our twin spool Inter Turbine Burner (ITB) equipped turbine engine is throttleable between 50 Hp to 700 Hp with a weight-to-power ratio (including gearbox) approaching .50 and possesses multi-fuel capability. A demonstration of this unique turbine technology, hybrid capable, marine applications is proposed. The Phase I TRL4 demonstration will include: • Demonstration that an ITB equipped turboshaft engine weighs five times less than a conventional diesel engine with comparable power and BSFC; • Investigation into technology optimization to withstand marine duty cycles and environments while retaining life performance; • Definition regarding multi-module stacking for larger applications to achieve commonality across a family of craft sizes; • Preliminary research into noise and vibration controls; • Estimates regarding mission flexibility, repair, and expeditionary land- based applications, and • Evaluation of hybrid type operations and distributed power applications. The option program defines an ITB equipped turboshaft engine optimized for implementation into advanced hull forms published in the Navy Expeditionary Combat Command Science and Technology Strategic Plan. Phase II TRL6-7 demonstration includes a marine configured ITB engine operational between 50 Hp to 1000 Hp, weight-to-power ratio (including gearbox) below .50 and BSFC less than .50. Installation into a pre-selected combatant craft will be investigated.

Title:Autonomous Shipboard Cleaning System
Abstract:Man Made Machines, LLC has developed a prototype (proof-of-concept) for a floor mopping robot, which has the capability to map its working area for an optimum on efficiency in energy & time consumption vice cleaning effectiveness. The specialty of this approach is an intelligent software, which enables work-area mapping at a BOM cost of about $100. This is about 10x lower then comparable devices. The robot is controlled in the current version by three MCUs; MCU1 is the main MCU (ARM-Cortex M3, 32 bit) which coordinates the movements of the robot and does the area mapping; MCU2 checks the sensors and gives feedback to MCU1; MCU3 activates/deactivates the motors and compares with the motor feedback. The Phase 1 proposal is based on the existing proof- of-concept and introduces an extension/addition, which enables the robot to clean also walls, overheads, counters and incline ladders.

Title:Multipurpose Automated Steward (MAS): A Versatile System for Autonomous Shipboard Cleaning
Abstract:ProtoInnovations proposes to develop a versatile autonomous shipboard cleaning robot that we call the Multipurpose Automated Steward (MAS). Shipboard cleaning presents a complex environment with requirements to clean floors, walls, counters, and overheads in confined and fully three-dimensional spaces that lack predictable geometry. Current state-of-the-art systems for industrial application in large, open, and primarily two- dimensional spaces are ill-suited for the Navy’s needs. Small iterations and scaling of current systems are unlikely to provide appropriate solutions; instead, we will design: an agile and scalable mobility system able to work both in confined and open spaces, a versatile and conformable set of cleaning tools for various jobs, algorithms for autonomously avoiding obstacles and sensitive electronics while efficiently cleaning all shipboard surfaces, and an open architecture for communications and control. The MAS design will be formulated through identification of requirements, cost/benefit analyses, and technical trades. The level of detail attained will be sufficient to demonstrate, through simulation, that all requirements have been met and the perceived cost and benefit of the MAS relative to current manual cleaning to determine feasibility.

Title:Detection/Localization of Mine Detonation Resulting From Unmanned Influence Sweep Operations
Abstract:The US Navy is developing remotely operated (unmanned) mine sweeping systems, and accurate information on the occurrence and location of mine explosions is required to provide critical real-time assessment of mission effectiveness. However, the means to determine the range and the bearing of a mine detonation from a surface craft does not currently exist. It is well known that detonations of conventional explosives, both in water and in air, produce broad-band, transient electromagnetic signals. And recently, QUASAR Federal Systems (QFS) has developed and field tested a revolutionary new electromagnetic direction finding technology which is termed Poynting vector direction finding (PvDF). PvDF technology has been demonstrated and tested on platforms in the air, on the ground and over water. The technology has been tested on broad-band transient signals from lightning (very similar to a detonation), short-duration burst signals, and continuous wave (CW) signals. These tests have shown that PvDF technology is fully capable of quickly and accurately providing the location of a mine detonation. As a result, we propose to optimize current PvDF technology to detect mine detonations and provide accurate information on the locations of the detonations. The development and optimization path we envision is described in this proposal.

Title:FAST-ACTS: Flexible Autonomous Support To Aid Context and Task Switching
Abstract:PEO IWS is currently developing the Undersea Warfare Decision Support System (USW- DSS). The USW-DSS will enhance the Combat Information Center (CIC) by providing a "Common Tactical Picture" to operators for shared situation awareness. To help define and improve the USW-DSS concept, solutions are needed that can improve CIC operators'' abilities to switch contexts and multi-task more efficiently. Aptima proposes to help fill this gap by developing Flexible Autonomous Support To Aid Context and Tasking Switching (FAST-ACTS). The FAST-ACTS effort will develop a software application that can provide the following aspects: (1) a model that monitors the operator''s actions based on primitive system inputs, such as button presses or mouse clicks, and determines with high probability what tasks or objectives the operator is performing; (2) a platform based on Cognitive Work Analysis (CWA) techniques that enhances the operator’s transition between tasks by visualizing task relationships within both global and local contexts; and (3) a module that tracks and visualizes the operator’s task history to help resume previous tasks more easily. Aptima’s in-house testbed, the DDD (Dynamic Distributed Decision- making), will be used to validate the feasibility and utility of FAST-ACTS without the need for a high-fidelity testing environment.

Title:Context-Aware Visualization for Tactical Multi-Tasking
Abstract:In the future, Navy personnel will be expected to perform a variety of different tasks and missions in a highly linked, collaborative environment subject to frequent alerts and interruptions. This situation will be operable for all newer class surface ships, which have an expanded range of missions within the context of an open system architecture. One major challenge is insuring that the human-technology interfaces for these systems eliminate as much as possible the heavy performance cost of context switching which occurs when personnel attend to different missions or tasks or respond to alerts and warnings. Infoscitex proposes to build the Support Environment for Automatic Context- switching User Experience, or SEACUE, a tool to help automate the selection and display of task-relevant context for human-system interfaces. The key to the approach is a deep understanding of both the nature of context in user interface design for Navy applications and of the domain in which the user interfaces must operate. This tool will produce highly effective interfaces that minimize the disruptive effects of context switching across Navy applications.

Abstract:Next-generation cruisers being developed under the U.S. Navy’s CG(X) program will have significantly higher power demands than the current Ticonderoga-class vessels. Therefore, this proposed program will address the need for low-cost, high-power-density cables based on HTS technology. It is anticipated that the results of this work will provide the Navy with a cost-effective means of efficiently distributing power to shipboard systems, while also reducing the weight as compared to currently-used copper conductors.

Title:Enhanced Electrical and Thermal Conductivity of Wires Drawn from Cast Cu/Nanophase Composites
Abstract:Multi walled carbon nanotubes MWNTs will be coated to enable wetting by molten OFHC copper. Coated MWNTs will be made into a preform and pressure infiltration cast with molten Cu to form a Cu/MWNT master composite. Master composites will be added to molten Cu and shear dispersed/diluted to form a melt that can subsequently be rheocast into Cu/MWNT ingots. The ingots will then be conventionally processed into wire for cable for shipboard electrical systems. The electrical conductivity of Cu wire can be increased by a factor of two to six depending upon the alignment of MWNTs, the proportion of MWNTs that have electronic (armchair) structure and the volume fraction of MWNTs incorporated into the wire. Electrical and thermal conductivity, OM/SEM/TEM microstructure will be characterized and mechanical properties will be measured on shear dispersed/diluted composites in Phase I. Phase II will be focused on integrating the shear dilution process with a rheocasting processes that can later be converted into a continuous casting process and for producing prototype lots of material. Phase II will also focus on identifying cost effective high performance MWNT sources.

Title:Lightweight High Power Metal Rubber™ Electrical Cables for CG(X) IPS
Abstract:This program would demonstrate the feasibility of replacing heavy high power electrical distribution cables with lightweight Metal RubberTM cables. Lightweight power dense cables are important as feeds from primary power transmission lines below deck to high power weapon and radar systems above deck. Metal Rubber™ is a low modulus self- assembled nanocomposite with electrical conductivity on the order of that of bulk copper (107 S/m). Its mass density (1 g/cm3) is much less than that of copper (8.96 g/c m3), meaning Metal Rubber™ cables may offer significant weight savings over conventional copper cables or superconductor-based cable installations which require refrigeration and insulation. Due to its mechanical flexibility, installing Metal Rubber™ cables after ship sections are interconnected would be easier than installing heavy, rigid copper cables or superconductor transmission line assemblies. During Phase I, NanoSonic would work with input from a major ship system manufacturer, and design, fabricate and analyze the properties of representative Metal Rubber™ cables. These hardware test articles will allow direct calculation of maximum current density and temperature, and total possible weight reduction. Technical specifications and weight considerations would be used to downselect optimal development paths during a possible Phase II program in cooperation with that ship system manufacturer.

Title:Vibration and Shock Test Machines for Large Ship Systems Components
Abstract:This work applies to US Navy requirements for shock and vibration testing of shipboard machinery, equipment, and systems. The work described in this proposal will produce the design for a combined shock and vibration testing machine capable of payloads up to 100,000 pounds. A combined shock and vibration testing machine can reduce the cost of testing by eliminating duplication of labor and equipment. No combined shock and vibration testing machines currently exist for payloads of this size. The proposed combined testing machine will extend established hammer technology to larger payloads with increased excursions and more realistic shock inputs. The vibration testing capability of the machine similarly extends mechanical reaction shaker technology to larger payloads and a larger platform than are currently available.

Title:Vibration and Shock Test Machines for Large Ship Systems Components
Abstract:This proposal describes an innovative approach to demonstrate a single test system to combine shock and vibration testing of large, complex component geometries weighing up to 100,000 lbs. This device will reliably and accurately supply shock inputs in accordance with MIL-STD 901D and sinusoidal vibration per MIL-STD 167. Our approach will employ our experience and expertise of using pneumatic shock generators with hydraulic vibration simulators, control hardware and structures to meet the challenges of this design. We must optimize the test structure to maintain load continuity over the appropriate frequency ranges for the necessary periods of time. Due to a large variety of test subjects with equally wide ranges of center of gravity and natural frequencies, the test platform will require the ability to counteract a broad range of systems and inputs. A control system which provides a simple means to configure test inputs in terms of acceleration, velocity and displacement will need to be developed. The successful outcome of this research will lead to a phase II prototype development designed to validate our approach and prepare for phase III commercialization.

Title:Layered Authoring of Ship Crew Agents for Recoverability Simulation (LASCARS)
Abstract:Naval ships are among the most complex and costly engineered structures in existence. Operating in harsh and hostile environments, some ships will inevitably suffer damage. Recoverability is a critical ship design criterion, directly linked to robustness of mission capability and life safety. Modern simulation-based approaches to acquisition and design depend on adequate simulation of systems’ performance under varying environment, mission, and state conditions. Crew behavior simulations are currently lacking, and are required for recoverability simulations that adequately reflect the realities of firefighting and damage control efforts. We propose to develop a system supporting Layered Authoring of Ship Crew Agents for Recoverability Simulation (LASCARS). LASCARS will exploit unique strengths of Stottler Henke and its partner Alion to support better ship design. Innovations will include (1) incorporating human performance simulations into recoverability assessments, (2) structuring the human models into representational and behavioral layers, enabling controlled growth in model complexity and resource demands, (3) providing authoring tools to ease creation, selection, integration and debugging of agent modeling layers, (4) designing for integration with existing physical ship survivability simulation tools and approaches. During Phase I we will gather requirements, produce a proof-of-concept prototype, and develop a detailed Phase II design and work plan.

Title:Expert System Simulation Capability for Recoverability Modeling
Abstract:Recent events such as the fire on the USS GEORGE WASHINGTON have shown that communications and decision making can have a dominant impact on scenario outcomes involving shipboard fires. The processes by which information is learned, disseminated, assembled, and processed have a direct effect on where, when, and what kind of response is mounted by the crew. Current recoverability simulations, such as the Integrated Recoverability Model (IRM) are able to realistically emulate the interaction and dependencies of ship’s systems, initial systems configuration(s), structural and equipment damage from weapon effects, fire, flooding, and stability. The IRM is also able to simulate crew actions over time, but provides overly optimistic predictions of crew actions. Test & Evaluation Solutions, LLC, in partnership with Soar Technology, Inc., and Hughes Associates, Inc. proposes to address the crew behavior limitations of the IRM by developing a crew behavior module that works with the IRM Simulator and existing fire and flooding modules. The Soar software architecture provides a powerful platform to address the most complex aspects of human behavior and paired with the IRM can enable an innovative solution to simulating damage scenarios, including a more realistic crew response.

Title:Shipboard Shock & Vibration Environmental Monitoring and Recording
Abstract:This proposal describes an approach to develop a small, rugged, stand-alone system to measure acceleration, velocity and displacement time histories of casualty events onboard ship. This device will reliably and accurately supply prognostic monitoring of mission critical assets from measured real-world casualty events. Additional benefits would incorporate recorded data for future ship design tools and models. Presenting this capability represents a cost savings by verifying the need for related testing while correlating real-time data to determine test levels. Further, knowing levels reached in a particular location allows maintenance of related assets on known fragility levels as opposed to arbitrary schedules. Our approach will apply our experience and expertise of accurate shock and vibration environmental measurement via autonomous ruggedized field data recorders. We must optimize the configuration with state-of-the-art technology to guarantee accurate measurements per naval standards while minimizing maintenance and cost. This requires demonstrating the feasibility of different power saving approaches and their effects on data integrity. Additionally, a mechanical design to minimize interference and maintain a small self-contained form factor will be proven. The successful outcome of this research will lead to a phase II prototype development designed to validate our approach and prepare for phase III commercialization.

Title:Shipboard Shock & Vibration Environmental Monitoring and Recording
Abstract:During naval operations, shipboard equipment is normally exposed to varying levels of shock and vibration. However, due to combat, accident, or severe sea states the levels of acceleration experienced by onboard systems may occasionally fall outside the range expected to occur during standard operation. When such an episode occurs of greatest concern is whether mission essential or mission critical equipment will continue to operate or if it was damaged beyond safe use. A technology that allowed such vital equipment to be constantly monitored, verified, and validated for continued operation after an instance of severe vibration or shock would be indispensable. To provide this capability McQ Inc. proposes to develop an electronic shock and vibration supervisor that will continually monitor and record acceleration experienced by important shipboard systems. The feedback provided by this system will empower decision makers to select the best course of action following a severe acceleration event.

Title:Shipboard Shock & Vibration Environmental Monitoring and Recording
Abstract:There is currently no integrated and systemic means of monitoring and recording the forces which lead to fatigue and eventual catastrophic failure of shipboard equipment. Such instrumentation has traditionally been reserved for highly controlled, instrumented sea tests such as shock trials. The surface fleet has an urgent need to develop and integrate an onboard shock and vibration monitoring system. Constellations of strategically placed sensors can measure the magnitude and record all such events which occur from normal underway operations and casualty scenarios such as the effect of hull slamming in high seas. This system will monitor, record, and aggregate acceleration, velocity, and displacement vector time series data across the platform. This data can be used to support predictive fatigue models for preventive maintenance as well as drive changes in new ship designs. Utilizing remotely attached sensors allows the selection of different sensor types for the specific application mated to common, programmable processing modules. Sensor placement on the device or structure of interest is particularly critical for accurate monitoring. The processing modules would contain configurable signal conditioning stages for several sensor channels, employ ultra low power processing with a multilevel power management scheme, wireless communications, and removable flash media.

CTD will work with key industry partners to demonstrate the material’s applicability to twist-lock connection systems by adopting an iterative design approach to be performed in tandem with the material development and evaluation efforts. This approach will produce a connection system design incorporating the developed technology, which demonstrates significant performance improvements over existing state-of-the-art connection systems.

Title:Innovative Shock Isolation Technology
Abstract:The Navy is developing a variety of mission modules with weights up to 20 metric tons for use onboard its next generation of high speed, focused-mission combat ships. The current design of these modules, which comprise ISO-standard support containers and off-board vehicles, must include provisions for shock mitigation to protect the sensitive internal cargo. By providing shock mitigation within the modules/seaframe connectors, constraints on both the modules and seaframe could be relaxed and significant weight savings would be achieved. Mat-IQ will use its expertise in advanced materials and prior experience in innovative shock and vibration mitigation to develop state-of-the-art isolation technology. Rigid connectors will be replaced with smart materials-based isolators capable of mitigating Grade B shock loading according to Navy MIL-S-901D, thereby allowing the Navy to reach its weight saving goals. The support and longstanding military and industrial markets experience of Barry Controls will ensure that Mat-IQ’s design will remain compatible with Navy requirements and current standard grade twist-lock connectors, and will facilitate the introduction of the newly developed technology into commercial markets.

Title:Advanced Shock Mitigating Materials
Abstract:Sensitive equipment critical to successful LCS missions have been damaged due to excessive shock loading. The shock is transferred to the mission systems through rigid twist-lock connectors which secure mission module ISO containers to the LCS hull. TRI/Austin proposes to investigate state of the art shock mitigating materials and structures to resolve this issue. A preliminary design of a composite enhanced twist-lock connector has been developed for this application which does not require increasing the distance between the ISO container and the LCS deck. The proposed design will provide resiliency at the critical mounting locations as well as create the potential for increased payload capacity due to support and container structure weight reductions. Phase I analysis and testing will confirm the viability of the selected materials and designs for full scale prototyping in Phase II. Other concepts, including commercially available shock isolators, will be explored to ensure the best solution is reached based upon design requirement satisfaction, cost, and potential for implementation.

Title:Modeling Electromagnetic Propagation Through Novel Materials and Configurations
Abstract:In this SBIR project, we propose to expand the brick tracing algorithm originally developed at the University of Michigan for indoor wave propagation modeling to a fully 3-D “Block Tracing” algorithm, in which a large structure is decomposed into a number of elementary blocks, either periodic or aperiodic. There will not be any constraining assumptions on the type or geometry of the blocks or on the wave incidence angles. The blocks can be made of complex materials with anisotropic electric and magnetic properties or with periodic insertions such as in metamaterials. Since each block is independent, one will be able to handle arbitrary numbers of conjoined dissimilar materials. The full-wave solutions of the individual blocks are calculated using regular or periodic FDTD or MoM solvers. The interactions among all the various and possibly dissimilar blocks are calculated using an iterative algorithm that captured all the edge and corner effects. All the algorithms will be fully integrated within EM.CUBE’s modeling environment, which is equipped with a powerful 3-D CAD modeler capable of handling a large variety of CAD formats such as STEP, IGES, STL, OpenFlight, etc.

Title:Discontinuous Galerkin Modeling of Electromagnetic Propagation Through Novel Materials and Configurations
Abstract:Wave Computation Technologies, Inc. (WCT) proposes to develop a new time-domain discontinuous Galerkin software tool for modeling electromagnetic wave propagation through complex material and configurations. This solver combines the discontinuous Galerkin (DG) method with the finite-element time-domain (FETD) method to allow discontinuous discretization of complex geometry and materials. The solver will be implemented for arbitrary anistropoic and dispersive meda, so that novel materials including metamaterials can be included in the design simulation. The DG-FETD solver is highly efficient for complicated problems because it allows independent meshing and resolution for different regions. The WCT team has extensive experience with the relevant computational electromagnetics algorithms, and is in an excellent position to develop such a computational electromagnetics software tool. The proposed time-domain solver will further extend the application domain of the conventional finite element method to include large array of frequency selective surfaces and other complex electromagnetic environments.

Title:Advanced Hybrid Energy System for Wet and Dry Submersibles
Abstract:The demand for greater and safer energy storage for the wet and dry submersibles has pushed the limits of current battery technology. This energy demand is in response to the need for extended underwater mission operations and advances in electronic equipment needed for greater combat effectiveness. By replacing the existing battery with a fuel cell hybrid system, extended operation periods are possible while reducing the safety risk. In a hybrid system the battery is used to handle start up and peak power demands while the fuel cell is used to provide the nominal power and charge the battery. This configuration allows for both components to be sized specifically for the power needed. To efficiently distribute the power, a proprietary power management system architecture is utilized that is able to adjust to the power demands and maintain a high system efficiency. The control logic which includes the power management system also monitors the system health to ensure safe operation. The development of a fuel cell hybrid system for these submersibles will extend mission times and increase safety.

Title:Advanced Power/Energy System for Wet and Dry Submersibles
Abstract:Yardney Technical Products proposes to evaluate several hybrid energy storage solutions for the SWCS and other manned submersibles. The first part of the Phase 1 effort will evaluate using Li-ion as the main energy storage with removable and replaceable higher energy density systems (e.g. primary cells) operating in parallel. To ensure the best options are considered, the proposed effort will advance the state of the art in submersible energy storage in two ways. First, the proposed effort will be the first to combine the state of the art in high energy silicon anodes with safer, phosphate based cathodes. Normally, iron phosphate cathodes are used in low energy, high power systems; the opposite of what is needed for SWCS. From these results and from existing YTP technology the capabilities of a Li-ion system will be reported both as a stand alone system and as part of a hybrid system. The second part of the Phase 1 effort will utilize experience from Submergence Group’s S201 submersible, presently using a fuel cell, to evaluate design options in which a fuel cell is the primary energy storage device and a battery provides secondary power.

Abstract:Described herein is a proposal for the development of a novel countermeasure technique against the passive millimeter wave (MMW) sensor. The passive MMW sensor has become an essential device in modern warfare, enabling detection or imaging of a remotely located object or scenery without illuminating a target. Moreover, the passive MMW sensor provides superior sensitivity even in low-visibility conditions. While this sensor is a powerful tool for US military, it becomes a major threat when used by enemies. Oceanit proposes to develop an effective countermeasure technique against the passive MMW sensor.

Title:Modeling Electromagnetic Performance of Large, High Power Phased Arrays
Abstract:In this SBIR project, we propose to extend the method of numerically constructed characteristic basis functions (NCCBF) that was developed under a pervious NAVSEA- funded SBIR for the modeling of coupling effects in large phased arrays. This efficient matrix compression technique will be extended to the fully 3-D case involving both periodic and aperiodic substructures. This extension will allow for the modeling of coupling between arrays of non-commensurate periodicities and their surrounding objects. By extending to mixed periodic-aperiodic substructures, we will be able to use the NCCBF technique to efficiently model antenna-platform interactions as well. All the resulting algorithms will be fully integrated within the EM.CUBE framework, which is capable of handling STEP, IGES, OpenFlight and many other CAD formats.

Title:Time-Domain Array-Scanning-Method for Efficient Modeling of Large and High Power Phased Array
Abstract:Modeling of infinite/large arrays of antennas is a challenging task because the combination of these antennas’ size, frequencies, and power of operation requires the use of modeling approximations beyond that available with current tools and methods, especially to understand the element-to-element coupling. Since each unit element can be complex structures on multilayer substrates, the methods also need to handle these scenarios. A full-wave time-domain simulation platform is proposed for efficient numerical electromagnetic models of large phased arrays. The algorithm is based on a full-wave array-scanning-method (ASM) periodic finite-difference time-domain (FDTD) method for efficient modeling of complex and large structures. Using the ASM technique, the modeling of infinite/large phased array can be performed via a single unit element modeling. The FDTD nature of the algorithms allows users to model complex structures (such as horn, slotted waveguide, and patch elements) and potential non-linear effects without algorithm modification or with minimum algorithm modification. Only a single PC is required to model arbitrary complex unit element and potential nonlinear effects due to higher power source at a wide frequency band.

Title:Periscope Antenna Active Cooling
Abstract:Aspen Systems Inc. proposes to develop a proprietary refrigeration based cooling system for submarine antenna mast electronics cooling. This system will be highly adaptable and have the capability to maintain lower than ambient temperatures at the electronics cold plate. A thermal prototype will be designed, fabricated and tested during the Phase I effort to assure feasibility of the system requirements to meet stringent submarine thermal requirements. A specialized highly refined and optimized evaporator will be utilized, along with a sophisticated microchannel-based condenser to maximize thermal performance while meeting efficiency, weight and volume requirements. The System will maintain the electronics cold plate temperature at 20 degrees C while dissipating heat to ambient temperature at 50 Degrees C. The miniature system is anticipated to be readily adaptable, due to its modular design, to multiple submarine platforms, where it can be utilized to enhance cooling and extend life of modern high power antenna and electronics circuits mounted in the submarine mast.

Title:Periscope Antenna Active Cooling
Abstract:The increased complexity of periscope antennas requires the need for advanced cooling methods capable of reaching 20°C and extracting 150-200 watts of thermal load, while fitting in the tight confines of a periscope base. Current convective and conductive cooling approaches have proved inadequate at dissipating the thermal load generated by the antennas, a problem further complicated by the fact that the antenna radome is a poor thermal conductor. This may lead to the premature failure of heat sensitive components. The typical external radome ambient temperature, to which heat from the periscope base is being rejected, is 50°C. TIAX LLC is proposing the development of a miniature-scale Stirling cycle active cooling system that could well fit in the available confined periscope antenna base space and can provide the required cooling load at the desired temperature. The Stirling cooling cycle is a closed thermodynamic cycle in reverse of a Stirling engine cycle for power generation. Stirling cycle coolers have been used for decades to provide cooling temperatures down to the cryogenic temperature range for various applications.

Title:Training Cognitive Situational Awareness for Multi-Platform Command and Control
Abstract:This proposal recognizes the complexity of the concept of Situational Awareness (SA) in the context of information-based warfare paradigms. The principal objective of the Phase I effort is to establish the reliability of an innovated “Boolean” approach to establishing SA scoring. Our approach breaks-down complex problems into identifiable measurable elements. Plausible tactical scenarios are established. Detailed SA elements are defined to measures if salient features in a complex problem space are perceived. The Phase I effort establishes a Web-based SA metric assessment tool (SAMAT) to host SA measurement curriculum. SAMAT supports controls that support start; pause; and step- through actions at desired SA measurement points. Experimentation is performed where SAMAT exercises synchronized scenarios across multiple USWDSS nodes using a scaled version of the USWDSS Build 2 Classroom Trainer Tactical Training Environment. The Phase I effort employs commercially available software to create record text, audio, and video recording of the SA measurement assessment experimentation. Upon completion of the experiment, analysis is performed to determine the viability of Boolean, objective, SA assessment. Debriefs from trainee responses and analysis of recorded data are used to establish the reliability of SA metric assessment and drive requirements for the Phase II SA metric tool prototype.

The hardware will provide quantitative data on the user’s mental state and help provide the rest of the group members information on each other member’s current mental state. The hardware will be couple with software that will provide the user with feedback and in future interactions will optimize the complexity of the information being viewed by the user so that each user is monitoring the maximum number of variables given their cognitive capabilities and mental state. Lastly, the hardware and software will be coupled with training. Progeny Systems fields the Afloat Integrated Learning Environment (AILE) and will incorporate new measures and training material so that forward deployed, at sea, and shore-based sailors will be able to increase their performance in complex, multi-variable group decision formats.

Title:Optical Array Shape Estimation (ASE)
Abstract:Current methods used to determine the shape of towed sonar arrays are limited to basic models that use data from heading and depth sensors. These sensors are prone to measurement noise especially during maneuvers. The research team recognizes that neither a fiber optic measurement system nor a physics based model can achieve the desired accuracy for array shape independently. Through the combination of Aither’s fiber optic shape measurement system and Makai’s physics based modeling of towed systems, the research team proposes the development of the Fully Integrated Fiber Optic - Towed Array Shape Estimation System (FIFO-TASE). The system takes the innovative approach of incorporating both the fiber optic shape measurement data with input from the physics based model to realize the shape and orientation of the tow cable and towed array system. In this manner, the fiber optic sensor data is used more effectively, where the physics based modeling allows for filtering of inaccurate data and improved results when in “noisy” tow states. The FIFO-TASE system builds on the decade of work conducted by Aither personnel in the field of tow cable and array shape sensing providing an innovative means of enhancing and improving the resultant shape estimation.

Abstract:Towed acoustic arrays are used by the US Navy to detect submarines. Knowing the shape of the array is critical for achieving optimal system performance. There is a need for Array Shape Estimators (AES) with greater accuracy, ease of use, and reduced cost. The research proposed here is targeted toward fulfilling these needs. We plan to work toward a fiber optic sensor that will measure the shape of a towed array with minimal input from telemetry sensors. During this phase I effort, we anticipate demonstrating proof of concept for some key issues including: -Demonstrating the possibility of shape sensing through 1km of fiber -Estimating the achievable system performance -Measuring the affect that power loss at optical connectors has on system performance

Title:Blind MIMO System Identification for Improved Emitter Classification/Identification
Abstract:Classification and identification of radio frequency (RF) emissions onboard US Navy ships is an important ingredient in keeping our sailors and marines safe around the world. Techniques to increase the number of emitter parameters measured by shipboard electronic support measure (ESM) systems are being introduced into the fleet. However, this approach brings new issues such as measurement distortions due to propagation and environmental effects. The main objective of the proposal is to estimate the distortions from environmental and propagation phenomena and to reduce or eliminate their affect. Since the quantitative description of distortion phenomena is usually unknown in advance and emitter signals are inaccessible to the signal analyst, this problem is best addressed by utilizing recent advances in the signal processing area of blind system identification. Our approach is based on algorithms for blind estimation and equalization of multiple-input multiple-output (MIMO) systems. In this effort we will develop signal processing techniques that aim to improve the measurement and estimation of higher order emitter parameters by employing MIMO system estimation, equalization and advanced higher- order parameter extraction. The proposed signal processing techniques will be studied and tested under different scenarios and for a wide range of system parameters and assumptions.

Title:A Propulsion-Enabled Control System for Precise Submarine Maneuvering
Abstract:U.S. Navy submarines are now equipped with a number of actuators, including directional thrusters, that can enable an unprecedented level of maneuverability with a properly designed and executed control system. In this Phase I project, Impact Technologies has teamed with L-3 Communications and Virginia Tech to develop an automated submarine propulsion-enhanced control (ASPEC) system to achieve highly-precise control for autonomous execution of course-keeping, mooring/unmooring, mine avoidance, and collision avoidance. The ASPEC technology features an energy-shaping controller coupled with an optimal control allocation scheme, a nonlinear estimation scheme, and a guidance system. The system has guaranteed robust stability and is designed to minimize the effect of uncertainties, allowing the system to maintain precise control even with natural imprecision in the vehicle’s dynamics and obtained sensor signals. A comprehensive study of the control capability, the vehicle’s general arrangement, and subsystem interfaces (integrated bridge systems, navigation systems) will be performed in Phase I. The prototype system will then be evaluated in a representative simulation environment to determine control efficacy and justify insertion in Navy platforms. The project team is uniquely qualified to ensure a successful transition to a Phase II program that will include sea trials on a representative underwater vehicle platform.

Title:Advanced Submarine Control
Abstract:Previous generations of secondary propulsion systems have played an insignificant role within the submarine mission profile. Existing systems are relegated to secondary considerations providing a minimal thrust profile supporting limited requirements such as mooring, adding marginal thrust to the platforms maneuverability profile to support navigation within a restricted waterway and as a last resort acting as a backup emergency propulsion system making minimal headway in the home direction. An integrated precision control system in conjunction with primary and secondary vectored thrust propulsion systems would provide the next generation naval platforms with mission specific capabilities ranging from enhanced littoral and minefield navigation to manual/automated mooring/unmooring capabilities. Individual components required to meet such precise control are under development or already exist but require an integrated approach to system control in order to provide the potential full spectrum of automated ship control. Such a precise control system could provide potentially enormous cost of life ship savings through reduced manning requirements, elimination of secondary support cost such as tug fees accrued during mooring evolutions as well as reduction in maintenance cost associated with existing secondary propulsion mechanical control systems.

Abstract:SSCI, in collaboration with MIT (Profs. C. Chryssostomidis and M. Triantafyllou), Olin College (Prof. D. Barrett), and Harvard University (Prof. G. Lauder), proposes to develop and implement a novel Integrated Precision Control System (IPCS) for marine vessels employing secondary propulsors as a part of the overall control authority. The IPCS will have unique capabilities since it will explicitly address the following issues: (i) Problem of control inputs affecting the dynamics in a nonlinear fashion that arises in the implementation of azimuthing thrusters; (ii) Nonlinear control allocation for the case of over-actuation of the vessel resulting from the use of additional control effectors characterized by nonlinear dynamics; (iii) Singularity avoidance and satisfaction of control effector constraints using one-step-ahead optimal nonlinear control strategy; and (iv) Retrofit adaptive fault-tolerant implementation allowing the azimuthing thrusters to be added to or removed from the overall control system with ease. In the base period of Phase I, the focus of the SSCI''s uniquely strong team will be on problem formulation, development of a control design model, IPCS design, and initial performance evaluation, while in the option period further performance testing will be carried out. Phase II will focus on implementation and in-water testing of the IPCS.

Title:Visual Signature Reduction Technology using Dynamic Camouflage Coatings
Abstract:Undersea vehicles, such as submarines, are vulnerable to visual detection in littoral waters. As a tactical aid, static camouflage patterns can be painted on vessel hulls to better blend the vessel to its environment. However, static patterns are not able to adapt to environmental conditions. As a means to greatly advance stealth, a new class of dynamic (adaptive) coatings will be developed to respond to various stimuli resulting in automatic color and brightness adaptation as a function of depth via photochromic activation. Further enhancements reducing visual perception include rendering the photochromic materials in fractal brightness and color. The development of useful environmentally stable photochromic coatings will provide a baseline to supplement, whenever possible, additional means to control the coatings’ contrast through changes in temperature (thermochromic) and through operator activation (electrochromic). Given the complexity of modeling the littoral environment, a fully instrumented university laboratory will be used to replicate conditions for simulated depths up to 150 feet. To ensure a robust, cost effective design, a proven systems engineering approach will be used to provide the Navy a coating which can operate in a variety of mission profiles while being easy for maintenance providers to apply and maintain.

Title:Design and Manufacturing Process Automation for Next-Generation Composite Missile Canisters
Abstract:Missile system combinations such as MK-21 / SM-3 have reached the total weight limit of ship-based launchers. Reduced canister weight would provide margin needed for increased encanistered missile performance without exceeding total system weight limits. KaZaK will work with Raytheon Missile Systems to design and demonstrate a replacement for MK-21, used with multiple sea-based missiles. Replacement of steel structure with more modern composites would save considerable weight. However, composite canisters made by more conventional manufacturing methods such as filament winding, braiding, VARTM, fiber placement or RTM would unacceptably increase cost. KaZaK propose to address both weight and cost while optimizing a form, fit and function composite MK-21 for pultrusion manufacturing. Pultrusion is a highly automated method for making constant cross section hardware at half or less of the cost of other composite manufacturing methods. In Phase I KaZaK will design pultruded composite corners, then test to verify they survive pressure loads resulting from missile launch. Our team will address multiple other design concerns including restrained fire, moisture permeability, and straightness associated with material transition from steel to composite. Phase I will conclude with confirming test results along with cost and performance predictions for a fully integrated composite MK-21 production unit.

Title:Advanced Aluminum Cost-effective Joining
Abstract:Friction stir welding (FSW) can produce stronger, lighter, and more efficient welds than any previous process. In aluminum assemblies, FSW provides improved joint strength, fatigue properties and crack resistance compared to conventional arc welded joints. One of the current barriers to widespread use of FSW is that the process generally requires the use of clamping systems that are often cumbersome, complex, and expensive. Texas Research Institute Austin, Inc. (TRI/Austin) will team with Remmele Engineering, Inc. (Remmele) to develop and demonstrate a new and innovative friction stir welding process enhancement, by which components can be efficiently friction stir welded without the need of expensive and cumbersome clamping systems. The use of the proposed new technology with FSW will offer economic advantages over the current FSW practice of using complex clamping systems. The new technology can make the FSW process more affordable by decreasing tooling costs and preparation time, and can increase assembly rates. TRI/Austin and Remmele anticipate that this new technology will facilitate the design of FSW assemblies for Naval applications that would otherwise be impractical due to the difficulty of clamping.

Therefore, Boston Engineering’s world- class team intends to provide a path to feasible Navy technology by “closing the loop” where other efforts have been unable. By combining instrumented control surface concepts, tested in both advanced DPIV and on free swimming vehicles, we can provide research and direction with a high probability of tactical relevance and applicability. The ability to rapidly prototype and test concepts provides the connection between basic research in the area of interest and logistical issues involved in their application such as vehicle control, mounting consideration (loading), maneuver possibilities, vehicle component layout, etc. During the design of new control surfaces etc., the team will develop them as a system and incorporate lessons from fish and marine mammals as is appropriate.

Title:Bioinspired High-Performance Hydrofoils (BIOFOILS) for Future Naval Undersea Vehicles
Abstract:The proposed BIOFOILS program will develop innovative designs and control concepts for bioinspired hydrofoils for use in future Naval undersea vessels. The program will incorporate novel structures and mechanisms inspired from aquatic mammals into the design and function of human-engineered biofoils. In Phase I, Innovative Technology Applications Company (ITAC), LLC and its collaborators will explore and parameterize foil geometries and maneuver performance of various aquatic mammals and fishes, and demonstrate via experimental and numerical studies the hydrodynamic performance of candidate bioinspired and engineered foils undergoing severe maneuvers in an unsteady flow. The research will focus on investigating the influence of highly evolved morphological structures on associated vortical flows, loading and hydrodynamic performance of these foils. In Phase II, the biomimetic exploration will be extended to include multiple modes of motion for promising aquatic mammal appendages, flippers, and fish to develop innovative formulations of biofoil designs. The end product will be a new class of high-performance biofoil designs that provide greater control and maneuver performance, and are more compliant to the surrounding turbulent flows than conventional control surfaces. The proposed BIOFOILS technology can potentially lead to changes in design paradigms for future naval and aerial vehicles with advanced capabilities.

Title:Dynamic Control Surfaces for Extreme Maneuvers of UUVs
Abstract:By exploiting fish locomotion principles, we are going to address truly difficult control challenges such as station keeping under large perturbations, rapid maneuvering, and trajectory planning and tracking. The analysis of biological control surface design, composition, and capabilities will be applied to nautical vessels to enhance performance and maneuverability and reduce detection. We will study the optimal shape and size of the control surfaces to reduce drag and increase thrust. The trade-off between stability and maneuverability is also an important design factor. In collaboration with Prof. Michael Triantafyllou (MIT) and Prof. David Barret (Olin College) we will demonstrate our results on small UUVs in their state-of-the-art laboratories.

Title:Enhanced Dielectric Barrier Discharge Devices for Active Control of Flow Separation
Abstract:One of the most important factors in improving aerodynamic performance of aircraft is the ability to control flow separation from lift and control surfaces. On many military aircraft, passive vortex generators are currently used to create high levels of vorticity along control and lift surfaces, but these are purely passive devices, and it would be more advantageous to create controllable levels of body force, turbulence, and vorticity to improve overall aerodynamic performance. What is needed is a practical technique for active flow control. Surface-mounted Dielectric Barrier Discharge (DBD) plasma actuators have been studied in several laboratories, and they are a potentially attractive approach to achieve active flow control. Creare, in cooperation with the University of Minnesota, proposes to develop an active transition and drag reduction control system based upon wing-mounted DBDs using asymmetric thrust generation to improve DBD performance. We will develop a system that is practical for actual aircraft application. The system will be characterized, packaged appropriately for aircraft installation, and made robust enough to both survive and function in real-world military scenarios.

Title:Plasma Enhanced Aerodynamic Control (PEAC) for Improved Rotorcraft Performance
Abstract:Innovative Technology Applications Company (ITAC), LLC, in partnership with the University of Notre Dame (ND), propose to develop an advanced plasma-enhanced aerodynamic control (PEAC) technology to significantly enhance the performance of vertical takeoff and landing aircraft, in particular the V-22 Osprey tiltrotor vehicle. Innovative open- and closed-loop PEAC concepts will be designed to increase lift and cruise efficiency, and reduce drag and aerodynamic download during hover of the V-22 tiltrotor vehicle. The program will develop concepts based on a pending patent by Bell Helicopters using University of Notre Dame’s SDBD plasma actuators. In addition to wind tunnel demonstrations of aerodynamic benefits on the V-22 vehicle geometry, a preliminary assessment of system requirements will be conducted, and a method for real- time actuator health monitoring will be developed and tested as part of laboratory experiments. The program will emphasize readying the PEAC technology for flight tests.

Title:Affordable Rotorcraft Air Vehicle Drag Reduction for Cruise Efficiency and Enhanced Lift Using Plasma Flow Control
Abstract:The V-22 Osprey can benefit from drag reductions in at least two areas: low angle of attack drag reduction will provide an improvement in the cruise efficiency and hover download reduction will provide an increase in cargo capability. Orbital Research, in collaboration with the University of Toledo, proposes to develop an innovative, affordable Plasma-On-Demand (POD) system to reduce the drag of the V-22 during cruise, improve lift characteristics during maneuvers and reduce download in hover. During the Phase I program, Orbital will experimentally demonstrate the effectiveness of strategically placed plasma actuators in novel configurations and compare the effectiveness with existing passive VGs on the V-22 geometry at representative flight Mach numbers. Additionally, in combination with novel actuator configurations, an experimental approach will be used to identify suitable dielectric materials to increase the plasma actuator effectiveness at high speeds. For the Phase I Option program, Orbital will investigate the effectiveness of the plasma actuator arrangements at representative Reynolds numbers via CFD and create a hardware integration plan – highlighting the key components to be considered at a system level.

Abstract:Navy Special Warfare divers are often tasked with missions that require autonomous operation, high levels of mobility, and protection from contaminated water environments. Currently, there is no integrated dive suit system that can meet these requirements. Crye Associates proposes the development of such a dive suit system. This effort is primarily an engineering and design effort, with the main tasks being: identification of the best materials and components available; engineering a suit system that carefully balances different performance trade-offs; and the development of a design that provides the best functionality and usability. New methods for specific sealing and attachment functions may also have to be created for this particular application. In addition, development costs and end user cost constraints must be balanced against performance.

Title:Advanced Self-Assembly Method to Fabricate Novel Nanostructured Fabric Coatings for Diver Protection from Water Contaminants
Abstract:NanoSonic proposes to develop a novel nanostructured fabric coating method to fabricate a full protection system for divers towards water contaminants. Specifically, the nano- skin protection system would be lightweight, flexible/non-restrictive (for diver mobility), durable (will not degrade with saltwater environment, UV exposure, or with chemical/contamination exposure), and comfortable. A novel, hydrophobic (water/chemical-repellant), and synthetic fluorinated polymer fabric coating that is impregnated with functional materials (for thermal insulation and antimicrobial properties) will be developed. Next a nanostructured hydrophilic fiber coating (to wick moisture/sweat) would be applied to the inner exposed fabric surface using NanoSonic’s molecular-level self-assembly process. The low mass-density and highly functional wicking coating would be built-up or “grown” onto new/existing fabrics in a layer-by-layer fashion using specialty molecular-level solutions of nanoparticles and polymers that are made in-house. NanoSonic specializes in the development of innovative, highly-functional nanostructured and polymeric coatings for fabrics, such as Metal Rubber™-Textiles (highly-electrically-conductive and robust nanostructured fabrics). Scientists would directly build upon this unique technology to: 1) fabricate the precursor nanoclusters and polymer materials, 2) combine the precursor materials and build them up in the appropriate molecular-level architecture onto the fabric, and 3) analyze and optimize the fabric coating for diver protection in contaminated waters.

Title:Form-Fitting HAZMAT Diving Suit System for Protection Against Contaminated Water for Free-Swimming Diver
Abstract:Dry diving suits currently available for use in category 1 contaminated water are not elastomeric. They are bulky, heavy, require assistance with both donning and removing and are therefore incompatible with the precepts of speed, agility, maneuverability and stealth, which form the foundation of modern combat diving. An entirely new design of dry suit is proposed, utilizing a highly chemically and biologically resistant coating on a dry diving suit. The innovative lightweight material will facilitate a new form-fitting, less restrictive suit that will allow combat divers to undertake missions with a greater degree of safety, while being protected from toxic chemicals and harmful pathogens that may be present in the water as well as maintain a high level of durability to abrasion. This will constitute a paradigm shift in dry suit technology.

Title:Contaminated Water Protection System for Free-Swimming Diver
Abstract:Paragon will leverage hardware solutions developed and tested for the existing Navy Paragon Dive System Open Circuit Umbilical supplied demand UBA for diving in contaminated Category I & II waters. Hoses, seals, valves and materials from this system can be used to serve virtually every function required to modify existing Closed Circuit UBA and dry suit systems to create what we have termed the Paragon Expeditionary Dive System. With hardening solutions and water contaminant valves already in place, Paragon will use its unique life support experience to address the additional physiological design challenges imposed by the closed circuit system to provide a better integrated, and more efficient system without compromising any portion of the diver’s effectiveness. Innovations include a contaminant compatible integrated mask and hood that, despite being a closed system, allows equalization of pressure, mask defogging, CO2 flush, and sufficient movement. An affordable dry suit (cost and maintenance) is also proposed with adequate protective characteristics, suit vent / buoyancy control, and valving / filter for protection against back contamination of the counter lung. Given directly relevant experience and hardware, Paragon is uniquely positioned to provide a feasible total system solution that is obtainable within the SBIR program.

Title:Over the Horizon Refueling (OTH)
Abstract:In Phase I, DTI will examine methods of increasing tanker stand-off to a distance of 25 miles from shore, and beyond. DTI will evaluate and design the power, communications, and deployment systems required to field a distributed-pump solution; and investigate the alternative of simply increasing the diameter of the pipe used in systems. The latter approach would only require the use a single tanker-borne dry pump, but would necessitate a bulkier, more expensive pipe, and would lack the scalability offered by the distributed-pumps solution. A massively distributed pumping scheme that uses many smaller pumps in series is extremely attractive if very flexible thin wall tube can be used, because the shipboard pipe volume would be reduced significantly compared to the present 8 mile system. However the recovery method of such a flexible thin wall system will need to be evaluated and developed. In Phase II, DTI will work with the Navy to refine these initial designs, and select the optimal approach for full-scale demonstration in Phase III.

Title:Combat Diagnostic Chest Dressing
Abstract:We will design and integrate an embedded electronic diagnostic system into an existing chest dressing to alert a caregiver to a developing pneumothorax so that the appropriate life saving intervention can be made. The venting of air from the intrathoracic space through a wound provides an indication of a pneumothorax. Until now no chest dressing can detect deteriorating conditions and alert a care provider. Additionally, electronics technology is now able to produce sensing without adding excessive cost of an already fielded chest dressing such as the HALO, Ascherman or Hyfin. The use of miniaturized sensory electronics including a novel microprocessor detection algorithm will be integrated into a compact, disposable unit capable of assessing state, allowing for the venting of air, detecting the vent, and triggering a visual indicator. Such as device could easily be adapted in future phases to a wireless communication embedded chip to communicate with field medic or corpsmen monitors such as the Mini-medic™. Phase 1 will embed the electronic module onto the HALO system to meet the program requirements of sized to fit most wounds, identical adhesion to wound sites as the current device fielded, and visual indicator to the occurrence of the vent.

Title:Pneumothorax Diagnostic Chest Dressing Pad
Abstract:To address U.S. Navy’s need for a diagnostic chest dressing, Physical Optics Corporation (POC) proposes to develop a new electronics-integrated Pneumothorax Diagnostic Chest Dressing Pad (NUMOPAD). The proposed NUMOPAD is based on a chest pad/dressing with multiple embedded sensors applied on the chest wound of the injured Warfighter and a display unit carried/worn by the medic/corpsman. The innovation in the system design offers low false alarm rate (FAR) (0.02%), real-time diagnostic capability for developing pneumothorax in chest wounds and wirelessly alerts the medic/corpsman to its occurrence. The dressing is hypoallergenic and resilient to perspiration and extreme weather and its use of flexible electronics offers a small form factor (< 1 cm thick, in various sizes up to 6 in. × 4 in). Use of low-power electronics allows continuous operation of 8–10 hours of the dressing using watch batteries. In Phase I, POC plans to develop an engineering design, assemble a proof-of-concept prototype to demonstrate feasibility of NUMOPAD and develop an FDA approval strategy for this technology. At the end of Phase II, NUMOPAD will reach technology readiness level (TRL) 4/5 and be ready for initial testing for potential transition to the field.

Title:ACCESS: Automated Comparison and Clustering of Entity Signatures
Abstract:21st Century Technologies’ (21CT) ACCESS (Automated Comparison and Clustering of Entity SignatureS) research effort addresses the issue of comparing entities such as human personas and networks, so that a more complete assessment of at-risk entities can be made within and across the various domains in which those entities interact. The Phase I effort of ACCESS will provide an effective similarity measure and clustering algorithm for the automated comparison of human signatures that arise within and across modalities and mediums so that personas of interest can be discovered among large databases of gathered intelligence. This similarity measure will be used to create higher fidelity personas and provide the means to detect asymmetric actors/at-risk entities that manifest behavior types of interest. Key components of the ACCESS Phase I effort include: 1) Identification of one or more useful similarity measures for clustering personas, 2) Experimental data to inform assessments of the effectiveness of the identified measures, and 3) Preliminary results identifying at-risk signatures. This builds directly upon existing 21CT technologies that generate signatures from raw data, providing the customer with the ability to determine signature similarity for the identification of persons of interest.

Title:Similarity Measures for Human Networks
Abstract:The search for entities of interest (either individuals or groups) in large behavioral datasets has emerged as a key need for irregular warfare, counter-insurgency, and counter-terrorism. This search requires measures of similarity between networks, and the combination of diverse multi-dimensional measures into a single meaningful scalar measure of similarity. To address this challenge, Aptima has teamed with two leaders in the field of human network research: Dr. Kathleen Carley from Carnegie Mellon University and Dr. Alex (Sandy) Pentland from the MIT Media Lab. Dr. Carley brings a meta-matrix framework developed for computational organizational modeling to the team. Dr. Pentland brings his sociometric network similarity measurement work, which introduces similarity measures based on data from new types of wearable sensors. Aptima’s work on human network similarity from a system engineering and network science perspective forms a third component and serves as a bridge. Testing of measures in Phase I will use a hybrid real-synthetic dataset. A hypothetical test case will represent a “person or group of interest” and the Aptima team will calculate measures of similarity between the entities in the dataset and the synthetic target of interest, analyzing the effects of varying levels of uncertainty on the similarity measure.

Title:True Colors: Persona/Human Network Similarity Quantification Software
Abstract:In response to Navy SBIR topic NAVY 09-149, “Similarity Measures for Persona/Human Networks”, Michigan Aerospace Corporation (MAC) proposes the True Colors system (TC): an application that utilizes a unique means of assessing, quantifying and understanding the relationship between N-dimensional vectors which represent signatures capturing the behavior and activities of individuals or groups. Unlike popular distance and similarity metrics, the TC technique for assessing similarity does not require normalization, works with mixed numeric and categorical fields, gracefully handles missing entries, and can function appropriately in the case of imbalanced or sparsely populated records. TC is based on several years of research conducted by MAC staff in conjunction with government and industry partners in applying Ensembles of Decision Trees (EDTs) to challenging problems in Data Mining and Pattern Recognition including clustering. Advantages to this approach, include confidence estimations and relative feature importance assessment. MAC will use anonymized human interactions harvested from the well-known Slashdot forums as a testbed to demonstrate TC similarity principles. Slashdot forums supply a wealth of information about authors, users, topics, and cliques of like-minded members. The ability to assess similarity between items of varied composition has key applications in business, biology, social network analysis and many other fields.

Title:Similarity Measures for Persona/Human Networks
Abstract:Under the ONR Large Tactical Sensors Networks (LTSN) program, we have demonstrated a semantic wiki application, SWIM, capable of dynamically assembling and organizing data from disparate sources into a semantic graph conformant to an ontology. Using SWIM, incoming information is linked, where possible, to existing entities in the semantic graph, with linkages subject to user validation via the semantic wiki. For this SBIR Phase I we propose to investigate and demonstrate expanding SWIM capabilities in two areas: a) iterative feature set matching algorithms that will hypothesize probabilistic persona-persona matches as a mechanism to suggest merges of existing entities. This capability will improve identification of individuals based on partial or fragmentary information. b) subgraph matching algorithms that assess similarity of evolving social network or persona role or behavior identification against canonical group structure templates. This capability will improve the association of persona with groups. We will also assess methods to structure concepts representing motivators of behavior, leading to future research connecting individuals, groups and ideals to specific predicted behavior patterns.

Title:Human Total Cost of Ownership Decision Support System (HTCO)
Abstract:Realistic cost estimates are essential to the acquisition process. This proposal argues that approaches such as Total Cost of Ownership fall short of assessing the full costs of an item to be acquired because they largely avoid one main source of costs (and benefits) of the products/system to be acquired – the human costs over a system’s life cycle. The proposed effort focuses on enhancing a revolutionary approach to identifying and incorporating the human costs of ownership into the acquisition process, the Human Total Cost of Ownership (HTCO) model. We propose to expand and tailor the HTCO taxonomy to meet the needs of Department of Defense acquisition, and to develop an initial design and architecture for an acquisition Decision Support System (DSS) that uses HCTO to identify, track, and manage human costs as separate Key Performance Parameters (KPPs) in an acquisition. The technical approach includes collecting and analyzing a baseline sample of case study data from Defense Acquisitions and using that data to expand and tailor the HTCO human cost taxonomy. Products will include a refined HTCO framework and a conceptual prototype of an HCTO-based DSS for DoD guidance related to identification of human-related costs.

Title:Intelligent Human-System Integration Costing Model Console
Abstract:The proposed work includes the design of a decision system capable of taking high-level human-system integration (HSI) design requirements and propagating those design decisions to their consequences to determine cost changes. We will capture the relationships between platform technologies, component classes, and system level parameters and the human systems integration elements. We will capture these and a myriad of other causal relationships from human factors subject matter experts and provide NAVSEA with a decision tool to help them visualize and understand the trades between requirements, design components and features, HSI elements and the related life cycle costs of alternate designs. The focus of this effort is to augment the current NAVSEA processes so that concepts can be easily or automatically evaluated for Human Systems Integration impact and be associated with an HSI impact parameter. This HSI impact parameter will give the decision maker better insight into how each concept compares in the human factors elements. This HSI impact parameter may decompose into subcategories such as manpower, personnel, training and habitability. These HSI parameters have a direct effect on life cycle costs and can be used to better predict and estimate these costs during the conceptual design phase of a program.

Title:Decision Support Aiding for Human-Systems Acquisition
Abstract:As the Navy continues to emphasize the Naval Capabilities Development Process for evaluating material and non-material solutions, the importance of quantifying the effects of Human Systems Integration (HSI) factors continues to increase. The objective of this Phase I SBIR is to provide Navy analysts comprehensive insight into the impact HSI factors have on system level performance and total ownership cost (TOC). The decision support tool will support a multi-step assessment process that traces warfighting capabilities to system requirements, measures of effectiveness, and eventually to the HSI factors that influence those measures. The results will be displayed in a multi-dimensional trade space integrating cost, schedule, performance, and risk. FTI will leverage a data integration framework initially developed for the AF and Missile Defense Agency. Innovative HSI performance measure utility functions will be developed and integrated into a proven cost versus performance trade space. A standardized TOC method capturing cost impacts of HSI factors, such as manpower and training, will be integrated into a common database enabling both HSI practitioners and acquisition decision makers to evaluate solutions. The Phase I program will validate Phase II requirements through interacting with Navy analysts. The Phase II program will result in a fully functional prototype.

Title:Infrared-Transparent, Millimeter-Wave Bandpass, Missile Dome Design
Abstract:This purpose of this project is to develop advanced coatings for use in tri-mode seeker domes for the next generation Joint Air-to-Ground Missile. The coatings will be deposited using innovative deposition techniques producing films of high optical and electrical quality that are very dense and highly adherent. The coatings simultaneously have high electrical conductivity and IR transparency of greater than 90% past 5ìm. The films will be characterized by optical transmission scans, electrical measurements, and EMI shielding from 10-50 GHz. Results of the EMI shielding measurements will be used to design band- selective millimeter-wave (MMW) filters. Furthermore, high temperature conductivity testing to 1000°C will be performed along with abrasion testing, and sand erosion testing. This data will assess the suitability of the different coatings for use in the tri-mode seeker domes. Optimized films will be deposited on IR substrates and incorporated into a coating structure to demonstrate the coatings ability to achieve a high transmission pass region in the MMW Ka-band (between 27 and 40 GHz) while achieving out of band rejection. This structure will be based upon computer modeling refined from the earlier testing of the EMI shielding performance.

Title:Infrared-Transparent, Millimeter-Wave Bandpass, Missile Dome Design
Abstract:Agiltron will develop an infrared coating and Ka-band pass filter that can be used in missile domes and windows. An electrically conductive doped silicon thin layer is proposed as the shielding layer to replace the current embedded metal grid for shielding out-of-band microwave and radio frequencies. Silicon (Si) and aluminum oxide (Al2O3), both with good environment durability, are proposed for the high and low refractive index coating materials for the anti-reflection (AR) for the 3 to 5 micron band. This coating will protect the window and meet the environment survival requirements. All three coatings will be applied using the same technique, electron-beam evaporation. Agiltron’s approach to the Ka-band pass is a multi-cavity Fabry-Perot etalon utilizing the interface reflectance between high and low refractive index materials, Si and Al2O3. The Phase I program will develop two structures, one with the two filters physically separated but operating together, and the second with the two filters integrated into a single unit.

The overall objective of this project is to design and build a field-deployable, real-time sensor for the measurement of TRO in saltwater to provide control of the electrolytic hypochlorite-enhanced seawater flushes to ensure discharge levels fall within a narrow range that is effective. Phase I will demonstrate the feasibility of the approach. Sensors chip will be fabricated and tested. Key to the success of the proposed sensing is the use of highly robust sensing electrode that is resistant to fouling combined with the high sensitivity technique and microarray configuration. The addition of reagents is eliminated, providing continuous and real-time monitoring capabilities. Direct detection of TROs will be carried out for various concentrations (i.e. chlorine/bromine or other mixed oxidant naturally formed species) between 10 and 500 mg/L. Laboratory studies to confirm the feasibility of proposed approaches will be performed in synthetic and actual seawater. During Phase II we will demonstrate the sensor performance integrated with commercial electrolytic generators in an operational environment.

Title:Development of a Total Residual Oxidant Sensor Development of a Total Residual Oxidant Sensor
Abstract:Recent efforts at improving shipboard operations have focused on desalination systems. One area in which manpower may be significantly reduced is in the monitoring chlorine residuals from hypochlorite enhanced streams that are used for periodic biofouling control flushes of microfiltration membranes. These are used for pretreatment of seawater prior to exposure to reverse osmosis membranes used for desalination. Another area of interest is the measurement of oxidant levels in potable water to ensure safe levels are maintained. Current manual methods are not an efficient use of resources. These manual methods require consumables and are not real time. Commercially available sensors are unable to survive or accurately measure levels of oxidant in the 50 to 500 ppm range. Halogen Systems proposes to adapt its Chlorine Sensor Technology Platform to provide long term measurement stability along with a level of performance necessary for monitoring the Total Residual Oxidant levels of hypochlorite enhanced seawater flushing and potable water bromine and chlorine measurement.

Title:In-Stream Total Residual Oxidant Detector
Abstract:To address the Navy’s need for a near-real-time in-stream (NRTIS) total residual oxidant (TRO) detector, Physical Optics Corporation (POC) proposes to develop a new In-Stream Total Residual Oxidant Detector (ISTROD) based on nephelometric, photometric, and deconvolution analysis. The innovation in using wavelength-multiplexed photometry enables the compact (1.5 cubic feet) device to detect different types of oxidants and to determine TRO level from numerical deconvolution analysis continuously and in near real time. Environmentally robust and capable of operating in harsh seawater environment, this system offers high reliability and availability level >3,000 hr and TRO measurement range 500 mg/L with ±5% accuracy. In Phase I, POC will assemble and test a proof-of-concept technology readiness level (TRL)-3 prototype to demonstrate ISTROD efficacy in a laboratory environment, utilizing a model seawater mixture of relevant compositions and bleach solutions over a TRO concentration range of 50 to 500 mg/L. In Phase II, an improved full-scale and stand-alone TRL-7 prototype with controller area network bus (CAN-bus) interface will be built and demonstrated using natural seawater and an electrolytic chlorination device to produced EHCE seawater. This prototype will be coupled to an operating chlorination process in a Navy natural-seawater test facility to prove its performance.

Title:Sensor for Continuous Detection and Reporting of Total Residual Oxidant in Hypochlorite-Enhanced Water Systems
Abstract:The U.S. Navy has significantly improved its operational capabilities in littoral and near- shore seawaters, which has resulted in the need to achieve much better pre-treatment of the seawater withdrawn from the often turbid and debris-filled shallow waters for the onboard desalination systems. Low-maintenance microfiltration is now used for pre- treatment, and it relies upon periodic electrolytic hypochlorite-enhanced seawater flushes. Increased littoral deployment of naval vessels has also seen an increase in biological fouling and clogging of vessel cooling systems, leading to the installation of electrolytic chlorination systems on ships and submarines to control biological fouling. Efficient electrolytic chlorination requires an active control feedback system in the form of a compact, near real-time in-stream detector capable of continuously detecting and reporting the total residual oxidant (TRO) content in the hypochlorite-enhanced seawater streams that the Navy uses for periodic biofouling control flushes. Efficient control/monitoring of electrolytic chlorine-generation systems requires a TRO sensor that will operate accurately, reliably and for long durations without maintenance in the marine environment. Pronghorn Technologies proposes to develop a proprietary halogen oxidant sensor technology with proven robust, long-term measurement stability to operate from 0 to 500 ppm TRO to provide near real-time control feedback in a seawater chlorination system.

Title:Development of a Total Residual Oxidant Sensor
Abstract:We propose to develop a compact, near real-time in-stream detector capable of continuously detecting and reporting the total residual oxidant (TRO) content in the hypochlorite-enhanced seawater streams that the Navy uses for periodic biofouling control flushes. Our detector is a compact chemical sensor that monitors oxidant analytes in water using laser Raman spectroscopy employing an immersible, nonfouling inert glass fiberoptic probe. Such a sensor will provide the required input for measurement of TRO in concentrated oxidant streams made with a variety of source waters including potable water, natural seawater, and estuarine sources for future advanced desalination systems. Raman is a well known tool for chemical identification in aqueous media that provides some unique advantages for the present topic. These include: • Application to a broad range of aqueous environments • Particularly sensitive to halogen-containing analytes • Detectable through inert silica optical fibers • Water turbidity enhances scattering and detection capability • No sample preparation or extraction required • Single detector capable of monitoring multiple analytes. For these reasons we propose to develop a compact Raman unit in a configuration consistent with the specifications required to allow utilization with Navy shipboard seawater decontamination units.

Title:Shipboard Waste Volume Reduction and Treatment
Abstract:The US Navy is seeking ways to treat typical ship-generated waste to minimize storage space required for waste storage during long-term deployments, with a special emphasis on the large items produced during cargo and ordinance handling. The best way to do this is to treat the waste as a resource, reducing its volume and producing useful energy or fuel from the waste decomposition process. Rather than incineration, which produces nothing of value, Adherent Technologies, Inc. (ATI) is proposing to extend its novel tertiary recycling process for plastics to the treatment of mixed shipboard waste. In this process, solid organic materials are converted into volatile compounds that can be used as gaseous or liquid fuel while the remaining solids are highly condensed and usually sterile and odor free, allowing for long-term storage and easy disposal. The process is closed and does not need emission controls. ATI will use their experience in treating diverse waste materials for the recovery of valuable components to design a modular unit to reduce the volume of shipboard waste and generate usable products from the waste.

Title:Rapid Retrograde Processing using a Navy On Board Ship Pyrolysis System
Abstract:Navy shipboard and cargo shipment and transfer operations generate large quantities of bulk waste and non-biodegradable waste products that (a) utilize valuable storage space aboard ship before it can be disposed of in port and (b) cannot be disposed of overboard within littoral waters because of international environmental legislation (MARPOL). The objectives of this program are to develop a system that will process biodegradable (food, cardboard, wood) and non-biodegradable (fiberglass, Styrofoam, glass, metal strapping/banding) waste to produce minimal residual waste and operate in an environmentally responsible manner. Infoscitex, with the support of QinetiQ North America, propose a pyrolysis system for on-board use. This system burns waste at very high temperatures without using oxygen and leaves behind an ash that is about 10 percent of the original volume and that can safely be stored aboard ship until it reaches port. To date pyrolysis has been used mainly for organic materials. In the proposed Phase I program a small laboratory unit will be developed to demonstrate the pyrolysis of non- biodegradable waste. This system will be designed such that it can be scaled up for shipboard use and be compact and easily retrofitted to existing platforms or installed on future platforms.

Title:Demonstration of Rapid Waste Reduction from Ships Using Hydrothermal Liquefaction and Compaction
Abstract:Waste management on ships is an important yet difficult task because as waste is generated by day to day processes, it accumulates and occupies valuable space aboard vessels. The waste consists of a wide variety of organic and inorganic constituents, some of which are high in water content such as food waste. A process that is capable of rapidly converting all of the waste into a dense media for efficient storage or capable of completely eliminate some of the waste is ideal. We propose to develop a process consisting of a hydrothermal liquefaction reactor and a waste compactor. The hydrothermal liquefaction reactor will convert organic materials into an energy dense fuel, while the compactor will condense the inorganic waste. Hydrothermal liquefaction is a unique technology that can depolymerize wet or dry biomass into fuel. This fuel can be then be burned to heat the reactor, essentially eliminating waste from the boat. In Phase I, a batch reactor will be used to demonstrate the feasibility of rapidly reducing the volume of solid waste aboard ships while producing fuel from this waste. In Phase II, the batch reactor will be converted to a pilot-scale continuous reactor to achieve more efficient waste processing.

Title:Subranging Superconductor ADC
Abstract:Using magnetic flux quantum as a unit of conversion, and coupled with on-chip ultrafast rapid single flux quantum digital circuits, cryogenic superconductor analog-to-digital converter (ADC) technology offers discriminating performance advantages over competing technologies in sensitivity, linearity, and sampling rate. Extension of the single modulator design with an innovative subranging architecture has a potential performance leap (>30dB) in signal-to-noise ratio and spur-free-dynamic range that will exceed the stated requirements. The subranging ADC concatenates the ranges of a coarse and a fine ADC through an inter-range interface, which presents implementation challenges due to its inherent complexity. Recent advances in mixed-signal design concepts for the inter- range interface, propelled by the imminent transition to the faster and denser next generation Josephson junction circuit fabrication, now enable realization of the proposed subranging architecture. In Phase I, we will not only design the inter-range interface circuitry but also investigate two new ADCs to reduce the interface complexity. The first realization of the subranging ADC in Phase II will be followed by construction and delivery of complete receivers in Phase III. Recently, we have made significant advances in demonstrating and delivering complete receiver systems by combining superconductor chips with other cooled and un-cooled electronics to Navy laboratories.

Title:Improved Dynamic Range ADCs
Abstract:This proposal presents an Improved Dynamic Range ADC methodology that addresses key limitations in current ADC technology with respect to signal-to-noise ratio (SNR) and output bandwidth. This proposal leverages existing designs and technology already developed by OmniPhase, and scheduled for commercialization by 2010. The existing OmniPhase design employs proprietary ADC processing to attain extremely high SNR and SFDR performance across the full output bandwidth, providing a spurious-free dynamic range (SFDR) specification of 80 dB. It also supports downconversion and decimation with programmable bandwidth of 10 kHz to 300 MHz and decimated sample rates of 100 KSPS to 400 MSPS over an input RF bandwidth of DC to 2.6 GHz. The existing design is modified to utilize a novel ADC approach to improve SNR performance to provide a SNR of 82 dB at a 500 MHz output bandwidth, and 100 dB at a 10 MHz output bandwidth. The modified design provides 13.3 Effective Bits at 500 MHz output bandwidth, and 16.3 Effective Bits at a 10 MHz output bandwidth. An additional ADC circuit and post- processing digital downconversion (DDC) path are added to the existing design to provide a 600 MHz output instantaneous bandwidth.

Title:Organization, Search and Manipulation of Large Databases of Face Images
Abstract:In this proposal, we present a variety of methods that will significantly lower identification time of any face recognition algorithm by reducing the overall number of “possible subjects” through the use of Indexing and Soft Biometrics. Based on our prior academically published experience in this area and current Phase II SBIR research and development (ONR N08-077 – Automated Entity Classification in Video Using Soft Biometrics), we will construct a solution that leverages soft biometric features (i.e. gender, age, ethnicity, hair color, etc.) in order to categorize individuals into specific predefined bins. These features can be extracted during the preprocessing or enrollment phases and used to develop a novel Feature Search Tree (FST) data structure to enable significantly improved facial recognition. An added benefit of our soft biometric approach is that learned features can be combined using our innovative “Morphable Template Model” in order to automatically construct galleries of high resolution photo-realistic facial images of subjects matching textual descriptions.

Title:FaceTracer: Organization, Search and Manipulation of Large Databases of Face Images
Abstract:Managing a large set of face images, whether in a biometric database, security/surveillance videos or a social networking site, presents unique challenges in automatic extraction of data, fusion of many features, and effective user interfaces. Unlike traditional biometric recognition, where an image is use to search for a potential match, our goal in face searching is to allow users to enter text queries and have the system return the most likely matches. We will further permit refinement of the query and possibly output a 3D model of a generic face matching the query. This effort builds on the team’s recent advances in efficient learning for automated face-feature extraction, indexing and user interfaces leading to the first-ever face-search engine. This effort will expand that prototype, adding features and addressing the critical question of multi- feature fusion, needed to be discriminative in larger databases. It will define a Service- Oriented Architecture for systems integration. The system has already been demonstrated on over 200,000 faces and a few features. The approach is designed for full scalability, and Phase I will take the testing up to millions of faces with more than 30 features computed per face, with adaptive refinement of queries.

Title:Soft Biometrics-based Annotation and Retrieval for Large Scale Face Database
Abstract:We propose to design, develop and evaluate a system for retrieval of face images using natural language-like descriptions. Our approach is largely guided by how humans perceive similarity between faces and incorporates a combination of soft biometric descriptions, local and global feature descriptors and manifold-based similarity measures and machine learning techniques. Using a reasonably-sized training face data set from widely available sources including the web, we design a series of machine learning techniques for annotating the faces using soft biometric features. A much larger face data set containing millions of faces is then annotated using non-Euclidean distance measures defined on face manifolds. Given a new face in an image or a video, we will design techniques for fast and efficient retrieval of similar faces. In Phase I, we will design the modules for automatically annotating a large face data set and a simple interface for retrieving faces similar to the given face. In Phase II, we will scale the approach to handle several millions of faces and demonstrate a prototype for fast matching of faces.

Title:Advanced Breakwater and Causeway Design Concepts
Abstract:We propose to develop an advanced breakwater and causeway system for operation in austere ports, with limited or no facilities, that will provide a complete solution to reliably enable the military to supply forces ashore with needed cargo and supplies. A ruggedly- designed breakwater made from high-strength fabrics can yield an area of reduced sea state conditions in which cargo transfer operations can be effective. A lightweight causeway, easily installed within close proximity to shore, will allow the cargo to be transported from the vessel to the shore. This effort will leverage previous experience with multi-body seakeeping analysis tools, nonlinear mechanical system simulation tools, and ongoing efforts involving technologies directly related to breakwater and causeway systems. Characteristic components of the breakwater and causeway will be analyzed to show the feasibility of approach in modeling the entire system; a process for analyzing mooring loads will be assessed and a simple example of a vessel moored to a floating, anchored structure will be performed; initial design details of the breakwater and causeway will be developed, as well as mooring techniques and system installation and removal concepts.

Abstract:The QED team’s design approach comprises a rapidly deployable breakwater, causeway and anchoring system. The study focuses on the systems integration of these elements with emphasis on delivery means and installation to meet the 48 hour readiness objective. This study builds on the QED team’s experience designing, fabricating, deploying and testing similar systems over the past fifteen years. The output of the Phase I study includes a defined CONOPS for the total system, conceptual designs of the primary components and procedures for storing, handling, deploying and recovering components at sea and/or from a shore site considering a range of environmental conditions and littoral situations. The conceptual designs will be supported by hydrodynamic and engineering analysis of various system configurations considering extreme environmental conditions and mooring loads. Specific research and evaluation will be conducted on unique materials for components including marine growth resistant elastomer coated fabrics, advanced fabric bonding and module-to-module attachment techniques. The Phase I tasks deliverable items include a CONOPS study report, a preliminary system concept study report and a final study report, each supported by oral presentations.

Title:Advanced Breakwater and Causeway Design Concepts
Abstract:The solution envisaged in this proposal is to use a very large floating mat (VLFM) as a floating breakwater. Depending on the elasticity, relative dimensions with respect to wave length and wave angle, a mat exhibits different levels of reflection and transmission. The dimensions, elasticity and wave angle will be optimized in an effective design to achieve the maximum protection in the target wave environment. The VLFM is not intended to act directly as a causeway, but rather as an environmental shield enabling existing causeway designs to operate under its protection thus supporting a layered defense approach. This layered defense approach enables the VLFM to be sacrificial during extreme events and repairable in calmer seas. It is expected to sustain local damage without catastrophic failure of entire system and without significant deterioration in system performance. Being a floating breakwater, it is also less sensitive to water depth and the specified 20 feet tidal fluctuation.

Title:Handheld Sonar Intercept Receiver for Divers
Abstract:As the use of commercially available diver detection systems becomes more widespread, Navy divers will face a greater risk of being detected while conducting clandestine operations. If a diver is conducting an operation in enemy waters where an active diver detection system is employed, the entire mission can fail and lives can be lost if he is detected. What is needed is a portable system that can detect the active system and provide bearing information to the diver before he is detected. AAC proposes to develop a portable diver acoustic intercept system that can detect high-frequency active emissions, provide bearing, and potentially provide signal strength and frequency information as well. This information will be provided on an intuitive display that will be designed to be as small as possible, with the end goal being a display that leaves the diver’s hands free. The entire system, including high-frequency hydrophones, processing electronics, and power source, will be compact and easy to implement on a diver. Because of the system’s small size, it will readily be applicable to UUVs and SDVs.

Title:Handheld Sonar Intercept Receiver for Divers
Abstract:Navy combat swimmers are vulnerable to intentional or unintentional detection by active Sonar while they are conducting their mission in the littoral environment. The Sonar’s that normally operate in the littoral represent the greatest threat to divers as well as smaller size undersea vehicles like the Swimmer Delivery Vehicle (SDV) and Unmanned Underwater Vehicles (UUV). In order for combat swimmers to avoid detection from these threat Sonar’s they must be equipped with an acoustic intercept receiver that operates with a wide enough frequency range to alert them of a potential threat. It is extremely important that the intercept receiver provide the combat swimmer with a bearing to the active source in order to make an informed decision as to the best direction to move in order to avoid detection. The intercept receiver must be packaged with a minimum size and weight footprint with a minimal power requirement. Ideally it should be integrated into a “Swim Board” like configuration with the intercept detection information overlaying the diver navigation information. So that the swimmer does not have to be distracted from his navigation focus to be alerted to the presence of and bearing to an active Sonar.

Title:Handheld Sonar Intercept Receiver for Divers
Abstract:Navy divers face ever increasing risk of encountering diver detection sonar systems during missions. With the growing commercial market of diver detection systems there exists a need for portable devices that alert a diver to the presence of high frequency or ultrasonic acoustic transmissions in the vicinity of operation. A unique diver interface to such system must be developed to support the diver operations. To make the system effective, bearing and frequency estimates of the acoustic transmission are provided under a variety of operational scenarios. Both visual and audible warnings provided to the diver will enable real-time adjustments in routes to mitigate the vulnerability risk. Our innovative hand-held receiver packaging approach provides the ability to monitor the system without adding significant hardware to the diver. The operator interface features an intuitive solution that function under extreme in-water situations. Signal Processing must achieve high sensitivity with low false alarm rates, therefore full spectrum; spectral redundant based signal processing techniques need to be considered to enhance detection and bearing estimates within limited space/weight/volume allocations. Progeny’s understanding of the acoustic intercept problem is critical to developing a low false alarm solution to this problem.

Title:High Efficiency WCDMA Power Amplifier for MUOS Handheld Radio
Abstract:The Mobile User Objective System (MUOS) is an ultra high frequency (UHF) geosynchronous satellite communication (SATCOM) system based on commercial 3G Universal Mobile Telecommunications System (UMTS) and Wideband Code Division Multiple Access (WCDMA) architecture. A well-known characteristic of MUOS signal is its “notch” in the middle of spectrum, which requires a highly-linear transmitter. Warfighters cannot charge their batteries at regular basis, hence the efficiency of transmitter is also important. To provide a low unit cost, high reliability communication capability for the warfighter, smaller and lighter weight communication devices, with high efficiency and linearity, are essentially needed. To design a highly efficient MUOS handheld transmitter, MaXentric proposes GreenAmp Mini which uses a dynamic supply modulator to provide an adaptive DC power to the power amplifier. The dynamic supply modulator tracks the envelope of the MUOS signal, and provides the appropriate DC supply power according to the envelope signal. Since the DC supply power is changing with the input envelope signal, the overall transmitter will not consume extra DC power in a low output power region. When the MUOS handset is not transmitting, the DC power is not provided to the transmitter, minimizing the power consumption in the system and improving the overall system efficiency, which increases the battery lifetime significantly.

Title:High Efficiency WCDMA Power Amplifier for MUOS Handheld Radio
Abstract:The MUOS system has a critical need for an efficient power amplifier capable of delivering 8W of RF power with a 2 to 3 dB higher peak-to-average ratio than typical WCDMA. Quantum Dimension’s approach is to provide technology innovation by incorporating cutting-edge RF circuit and system design with advanced digital signal processing. Our approach involves: new transistor technology with increased efficiency, use of Doherty circuit topology, pre-distortion and peak envelope following that dramatically increases efficiency. It minimizes risk and complexity in order to meet challenging efficiency and output power requirements. While other researchers have focused on specific applications of envelope following, we feel that combining our innovative RF design with advanced signal processing more effectively increases power efficiency to meet >50% improvement as required for MUOS. We will study present PA transistor devices for handsets and select the most appropriate technology. Additionally, we develop and model large RF bandwidth methods and simulate Doherty PA structures with peak envelope following and pre-distortion for Class AB and Doherty PA’s. This allows us to quantify fundamental performance and employ system models. Finally, we develop signal and system models with current drain and distortion estimates for Doherty PA with pre-distortion and peak envelope following.

Title:RF MEMS-Tuned High Efficiency Power Amplifier
Abstract:XCOM Wireless is a small fabless semiconductor and RF MEMS component developer. XCOM focuses on component products for Defense prime contractors and the commercial test and instrumentation communities. This program employs several emerging technologies to substantially improve the efficiency of high-power RF amplifiers, and enable radios to adapt to changing power levels, frequencies, battery conditions, antenna mismatch, and other operational problems. The program objectives are to design and fabricate an RF MEMS circuit that tunes a power amplifier’s output matching circuit. The MEMS are fabricated by the contractor, and the amplifier circuit will be assembled out of high-power discrete transistor and passive components on a compact custom board. Actual hardware can be built and tested at low cost in this Phase I effort because all MEMS and transistor elements have already been designed and, in some cases, already qualified as industrial-grade COTS components. The result of this Phase I will be the first high-power (8 Watt, 280-320 MHz) amplifier that can adapt to changing conditions and perform at a consistently high efficiency regardless of typical operating conditions and output impedance variations.
