| Title: | Development of enhanced active damping system for the Marine Corps Expeditionary Fighting Vehicle (EFV) |
| Abstract: | A road wheel suspension incorporating a semi-active damper and fast load leveling spring system will be developed for the Expeditionary Fighting Vehicle (EFV). The system will be designed as a replacement for the currently fielded semi-active suspension system in the same foot print, either in early production units or as a retrofit package for incorporation later in the development cycle. A suspended seat will also be evaluated to mitigate shock and vibration transmitted into the EFV crew during both land and sea operations. In Phase I, a conceptual design of all the major components for the roadwheel suspension as well as the architecture for both control hardware and software will be developed. Dynamic modeling will be used to predict system benefits and provide requirements to the design process. The improved suspension will target equivalent functionality with greatly improved shock, vibration mitigation and improved dynamic stability. The Phase I Option will be focused on generating a detailed layout of the roadwheel suspension based on the component specifications and packaging constraints identified in Phase I. This will provide the basis for the detailed design and fabrication of a prototype system capable of withstanding extended proof of concept testing in Phase II. |

| Title: | Technology for Advanced Ship Designs: SEA-Pro |
| Abstract: | Electrical system design requires several studies and calculations be conducted to verify proper operation of the system and specification of equipment. This includes fault current calculations, load analysis, motor starting analysis, harmonic analysis, generator response studies, electro-magnetic interference, breaker coordination, etc. Software applications are available for conducting many of these studies. Commercially available packages, however, were originally designed for land-based facilities, which were not intended to address the unique requirements of shipboard installation. The shipboard installation requirements do, in fact, significantly affect the original system design parameters. Because shipboard requirements are currently not integrated into the original system modeling and analysis, much of this analysis requires later modification. Also, because the data developed during modeling and analysis is not readily transferable to shipyard production requirements, much of the data input requires duplication, which increases production costs and introduces errors in equipment procurement and installation. SEA-Pro will reduce design and production costs by providing an integrated marine electrical engineering analysis and production capability to the US Naval and commercial shipbuilding industry. The tool will also lend itself well to lean design/manufacturing assessments by providing a marine specific model of the vessels electrical production requirements. |

| Title: | Pultrusion-Based Fabrication of Revolutionary Phenolic Foam Replacement for Balsa in Navy Ship Structures |
| Abstract: | KaZaK Composites proposes development of a revolutionary fire resistant structural core material that will ultimately become a replacement for balsa in Navy sandwich panel construction. Balsa is currently the baseline material for structures like the DD(X) composite deckhouse. However, this baseline material has a number of shortcomings including inconsistent material properties (because it is a natural material), moisture absorption and associated degradation, and absorption of a considerable weight of resin during the VARTM manufacturing process. KaZaK's phenolic-based alternative will have far more consistent mechanical properties, and has been formulated to improve fire and impact resistance. KaZaK will also demonstrate an innovative manufacturing process for making sandwich panels of the type used by DD(X) that, once perfected, will greatly reduce the cost and simultaneously improve the performance of composite sandwich marine structures. In Phase I KaZaK will fabricate a large number of core material formulation alternatives and subject them to mechanical and fire tests to evaluate their relative performance. In addition sandwich panels will be constructed using a unique processing approach, tested in bending and impact, and results compared to balsa. Results will be reviewed by NGSS and other shipbuilders as part of KaZaK's regular meetings with our existing customer base. |

| Title: | Technology for Advanced Ship Designs |
| Abstract: | The cost effective intergration of a fire protection system into a multifunctional composite structure is a goal of the shipbuilding industry. The current practice of fire protection blankets over composites for fire protection is costly, difficult to maintain, difficult to install and ineffective for several threat scenerios. Structural Composites proposes to refine a new innovative Spray Bag composite fabrication process to provide fire protection. This innovative Spray Bag material facilitates the composites' infusion fabrication process and remains as part of the structure as the fire protection system. The major technical challange which list project will address is the ability to spray an elastomeric coating that has inherent fire protection directly onto dry fiber reinforcements, frames and ports in such a manner that will form a vacuum-tight bag directly on the fabrication mold. |

| Title: | Material Investigation for Navy Composite Sandwich Panel Solutions |
| Abstract: | There are various performance drivers that affect composite sandwich panel construction for Navy applications. Among these drivers are fire performance, structural properties, impact resistance, durability and cost. The sandwich panel material system includes the core material, the facings, the resin system and secondary coatings or facings; all of which can be varied to obtain specific sandwich panel properties. Currently, there is no single material system that provides excellent performance in all of the above areas; in fact many performance drivers run counter to each other when attempting to optimize materials for a given application. This makes material selection problematic and can lead to a circular approval pattern where one group's design drivers can steer the material selection such that it negatively affects performance in other areas or overall panel cost. This program will evaluate several material systems for use onboard Navy ships, these material systems include PVC foam core and balsa cores as well as various forms of the TYCORr material. An array of constructions that have varying degrees of fire performance, weight and cost will be manufactured and tested with the goal of identifying multiple material combinations that are both cost and weight effective, and offer fire protection that is tailorable to the fire threat for the application. |

| Abstract: | This program creates the design of alight weight, composite, load bearing superstructure for surface ships. The program is supported by Bath Iron Works (BIW) as a Navy Ship contractor. BIW will supply details of structural loading and impact requirements. WCT will design an isogrid reinforced panel structure to accept the loading conditions. Mounting requirements for components are examined and the isogrid system geometry is developed and modeled. Mounting inserts are evaluated for pullout loads and environmental conditions. Pro Engineer and Laminate Design modeling techniques are used to confirm the design. Test data from an existing DOD contract will be used to support mounting design. Panels are closed out with composite skins, one face by co-curing, the other by bonding. Carbon foam will be considered as a fill medium within the isogrid core. This will enhance the bond strength to the closeout skin and provide enhanced strength to the panel. The option program will cover design, fabrication and test of a prototype composite panel. In addition to structural testing, the component attachment system will be tested. Test results are evaluated and an optimum panel design and mounting system are created, leading into a Phase II program. |

| Title: | Simplified Hybrid Stanchions and Lightweight Composite Concrete for CLF Ships |
| Abstract: | KaZaK Composites proposes to develop and implement improvements to current CLF dunnage systems by designing and prototyping a cost effective adjustable stanchion and lightweight concrete. Key requirements for a redesigned dunnage system include elimination of wood dunnage, supporting structural loads, significant reduction in total ownership costs, easily repaired system components, light weight, ease of use and high toughness. Adjustable stanchions will be designed to meet and/or exceed existing load requirements, reduce stanchion weight, withstand environmental conditions (hot, cold, wet), take rough handling and meet fire performance specifications. Lightweight concrete will be formulated for use between diagonal and athwart ship steel rail CLF dunnage systems. Proposed dunnage systems must not impact restraint systems/operations or require costly ship modifications. By engaging CLF ship dunnage systems, KCI and the Navy are insured that developing designs will be compatible, effective and where applicable interchangeable. In Phase I KCI will perform extensive design trade studies, including finite element analysis of critical load conditions, followed by fabrication and testing of key sections of dunnage hardware to validate performance predictions. Composite parts will be tailored for fabrication via the pultrusion process, the least costly manufacturing technology for constant cross section shapes. |

| Title: | Pultruded Composite Structures for Cargo Stowage Systems (MSC P1T11-429) |
| Abstract: | Conventional cargo stowage systems (CSS) aboard Navy ships employ a steel rail diagonal dunnage system that is heavy and requires extensive use of wood block fillers between the stanchions and cargo to properly secure and restrain the cargo. In order to reduce shipboard weight and maintenance requirements, new lightweight material solutions and more efficient CSS structural designs are desired. The proposed research addresses the development and demonstration of new lightweight, damage tolerant, pultruded fiber-reinforced polyurethane composite structures for Navy ship cargo stowage systems. More efficient, lightweight composite structural design concepts and new fire-resistant polyurethane resin formulations will be applied to meet the multifunctional performance requirements of toughness, strength, stiffness and low flame, smoke and toxity. In order to ensure success and provide a path for shipboard integration and Phase II/Phase III commercialization, the proposed research will be carried out by an Integrated Product Team (IPT) consisting of composite material and structural designers and pultrusion processing experts. |

| Title: | Advanced Structural Development for Cargo Stowage Systems |
| Abstract: | U.S. Navy Combat Logistics Force (CLF) ships require cargo stowage systems to secure palletized and non-containerized cargo in the ship's holds. The current steel rail diagonal dunnage cargo stowage system is heavy and requires extensive use of filler material such as wood blocks to fill space between portable stanchions and the cargo. Weight and maintenance savings could also be realized by eliminating the concrete deck filler material used between the diagonal steel rails in order to level the surface for travel of fork lift trucks. This project proposes to develop a cost effective, lightweight, corrosion and fire resistant, durable, composite cargo stowage (CCS) system, that will meet or exceed the structural and environmental exposure design requirements for U.S. Navy CLF ships. The CCS system will consist of composite stanchions, adjustable locking blocks, overhead and deck rails, and deck tiles. The CCS system components will be constructed from composite materials that will meet all U.S. Navy CLF shipboard requirements including structural, fire, smoke and toxicity, and all environmental and chemical exposures. The proposed CCS system will allow for flexible stowage configurations that can be rapidly configured by minimal ships personnel and will be forklift compatible. |

| Title: | Comprehensive Spectrum Management for Wireless Networks |
| Abstract: | Wireless local area networks (WLANs) have become standard technology for government, commercial business, and DoD networks. With this widespread proliferation of RF technology has come a myriad of problems such as how to architect the WLAN for optimum performance, how to easily set-up and configure the WLAN and how to secure the WLAN to protect it from hackers. Solutions for such problems are available and still evolving. However, a newly recognized and just as insidious problem has gotten a lot of attention recently; that is the problem of Spectrum Management. Develop advanced hardware and software technologies for analysis and management of the RF component of shipboard wireless networks. In this SBIR Phase I we plan to demonstrate the feasibility of spectrum management for a wireless network system that utilizes the common unlicensed frequency bands and has the ability to shift to other desired frequency bands. The solution developed will address improvement of throughput through avoidance of interference as well as the ability to avoid the usage of specified frequencies when required by policy. We will accomplish this through the use of extensions to an existing WLAN Management System coupled with adding special purpose spectral analysis ICs to wireless Access Points. Comprehensive spectrum management will include provisions for spectral analysis and characterization as well as RF emitter location techniques. Advanced power management coupled with the use of directional and smart antenna technology is another key aspect of this project. The primary focus will be development of system suitable for handling the complex shipboard RF environment. The system will be capable of being used for Naval and military applications, including requirements for ruggedization, electromagnetic compatibility, information assurance and open architecture. The developed solutions will also have applicability for typical shore-based installations as well. |

| Title: | Comprehensive Spectrum Management for Wireless Networks |
| Abstract: | To mitigate the parasitic characteristics of radio channel, an intelligent RF control plane is desired. Spectrum Management for shipboard wireless modems, consideration for on shore equipment support, emphasis on exiting Wireless LAN protocols (802.11) with consideration for ultra wideband and even IR WLANs, are all required for maximizing radio functionality without having to maximize radio expertise. These requirements dramatically reduce the cost and complexity associated with building a business critical wireless network. A savvy spectrum management system is proposed for frequency coordination of shipboard wireless modems. This system utilizes sophisticated self-organizing interference, emission measurement, and prediction subsystems to determine the best suitable frequency band of operation. The proposed system also employs highly frequency agile front-ends for all its nodes to allow operations in the specified bands. The system will optimize throughput, power, and interference for a wireless networks, taking into account regulatory mandates. |

| Title: | Cognitive Radio Utilization and Integration of Spectrum Emission |
| Abstract: | To address the U.S. Navy need for a wireless network spectrum management system for the common unlicensed frequency bands and that can shift to other frequency bands, Physical Optics Corporation (POC) proposes to develop a new Cognitive Radio Utilization and Integration of Spectrum Emission (CRUISE) system based on software defined radio transceivers and novel cognitive radio techniques. In particular POC will extend the present media access control elements of the 802.11 protocols to address issues arising from hidden and exposed nodes, particularly within directional systems. POC will develop a system for flexible frequency and modulation control. This will reduce bandwidth saturation, automatically reroute network traffic around physical obstacles, ensure data packet fidelity, adjust transmission power to eliminate interference with neighboring transceivers, and extend the range of 802.11 wireless networks by using each network node as a repeater to relay messages to remote nodes. In Phase I POC will demonstrate the feasibility of CRUISE network technology by building a technology demonstration unit to validate all key fundamental principles. In Phase II POC will develop several advanced CRUISE prototypes, which will prove all aspects of its advanced, adaptable, and revolutionary network architecture. |

| Title: | Sensor Synchronization Technologies |
| Abstract: | Shipboard condition monitoring, condition-based maintenance, measurement, and control systems involve the exchange of information among one or more controllers and numerous sensors and actuators. Correct operation of these systems requires that the temporal relationships of the sensor readings, actuator settings, and controller computations be synchronized. Navy desires to achieve the time synchronization of events on all sensors especially the smart/digital sensors utilizing standards and open architectures as much as possible. Under Phase I of this SBIR, 3eTI's Team will perform Tradeoff Analysis for time synchronization technologies. Based on our initial study, we will implement the open standard IEEE 1588 for Precision Clock Synchronization Protocol for Networked Measurement and Control System in the following steps: (i) Developing the IEEE 1588 software and implement it on the 3eTI NCAP platform. (ii) Prototyping the IEEE 1588 time synchronization with IEEE P1451.3 and P1451.5 smart sensors using NCAP as the core platform integrating the smart sensor networks. (iii) Based on performance data, further software and hardware based optimization will be proposed. 3eTI's vision is to develop a unified solution that provides time synchronization support to heterogeneous smart sensor network simultaneously. A report will be provided that details the concept, suggested metrics and estimated life-cycle costs |

| Title: | Sensor Time Stamping for Mixed IEEE 1451 Network Protocols |
| Abstract: | Many applications require that the precise time at which a sensor reading is taken be known. However, time correlation of data obtained from sensors which are distributed over a network or several networks are subject to errors or misinterpretation because different time stamp formats are used, the clocks used for the timestamp may be inaccurate and there may be uncompensated delays in the network data transmission. We propose to provide a precise time stamp which would be built into, or easily added to, all networks which use the IEEE 1451 smart transducer format. It would have time resolutions ranging from microseconds to seconds and not necessarily rely on the Internet or Ethernet network for time synchronization. NIST-based radio time clocks and features of the IEEE 1588 synchronization standard will be used to implement the reliable timing. The Phase I prototype will consist of an Internet type NCAP and two IEEE 1451.2 (RS232) TIMs with an actuator and sensors. |

Terrorist threats and other examples of asymmetric warfare are replacing traditional nation-to-nation threats.

S3Net will process and collect data from existing mature sensors using time synchronization protocols based on IEEE 1451 standards and open architecture, wherein each smart sensor determines the sample timing based on the trigger or time obtained from the synchronization clock. The association of the data values and their time stamps will be performed at each sensor. |

| Title: | Power generation for weight and space limited USV systems |
| Abstract: | Synchrotek Inc. proposes to design, during phase I, a 40 kW high frequency generator set for application in Unmanned Surface Vehicle (USV) platforms as a power source to support command and control equipment/modules. The design is based on Synchrotek's Variable Speed Constant Frequency (VSCF) technology. It uses a lightweight twin-cylinder rotary engine as prime mover. The generator is a lightweight permanent magnet generator, which produces variable voltage, variable frequency output when connected to the variable speed engine. An electronic power converter converts the generator output to precise power for AC load at constant voltage and constant frequency, or for DC load to precise DC voltage. The entire system is optimized for the lightest possible weight, expected to be less than 650 lbs. Additional benefits of the VSCF system are improved efficiency of the generator and the entire system over a range of load. This is achieved by controlling the speed of the engine for varying load conditions by an electronic speed controller that senses the load and adjusts the speed. Synchrotek has developed several gen-sets for the Army CECOM, as R & D Effort. Among them are the 3 kW and 5 kW generator/Inverter systems. Synchrotek has developed in-line generator for the Army for a constant speed application that produced 10 kW output at 120/208 V, 3ph, 60 Hz at engine speed of 1200 rpm. The generator is designed for speed range of 800 to 3400 rpm. Three prototype units have been incorporated into HMMWV system for field tests. The proposed high frequency generator will be designed with similar physical parameters, but for variable speed application. The phase I work effort will consist of a comprehensive assessment of mechanical, electrical and thermal trade off for an optimum configuration of a 40 kW generator coupled to a rotary engine The effort will address the electrical, mechanical and thermal considerations of the generator. The phase 1 effort will also evaluate its performance with the Power Electronics package to ensure 40 kW power at precise voltage and frequency and to generate drawings for fabrication of the generators during phaseII. |

| Title: | Lightweight Power Generation for RHIB Platforms |
| Abstract: | Military USV platforms require an increasing amount of electric power to support electronic systems developed for command and control and other loads. Combined with the fact that existing generator sets that provide the 40 kW of required power are too large and heavy for these boats, alternative solutions need to be found. UQM has developed small, lightweight generator solutions for hybrid electric vehicles used within ground vehicles, and can take this technology into RHIB platforms. Several small diesel engines exist as good candidates to become the prime mover of a UQM permanent magnet generator. The conditioned DC power is then fed to one or more AC power inverters for the creation of 60 and 400 Hz power. The feasibility of combining existing and/or modified components will become the focus of the Phase I effort, with the fundamental approach to minimize component development. UQM believes that the building blocks to create a lightweight (less than 400 lbs) generator system exist, and that good systems engineering will become the challenge. Issues of focus include component maturity, component interactions/compatibility, marine environment suitability, and systems-level tradeoffs. |

| Title: | Multi-function Connectors for Shipboard Equipment |
| Abstract: | The United States Navy is developing a multi-mission surface combatant called the Littoral Combat Ship (LCS). The present design supports anti-submarine warfare (ASW), mine warfare (MIW), and surface warfare (SUW) mission packages. It also provides underwater vehicle, aerial vehicle, and weapon zones for attaching mission modules. LCS's objective is to support a complete mission change-including an operational test (OPTEST)-within 24 hours. We propose a Pod ConnectorT for rapidly and securely attaching mission modules to a ship's deck. The Pod ConnectorT is self-stowing, watertight, and dirt-free. When the Pod ConnectorT is not in use, it stores upside-down and creates a watertight seal. Unlike protruding fasteners, which are damaged by loading apparatus (e.g. grabs and bulldozers), and recessed fasteners, which fill with dirt and water, the Pod ConnectorT stores flush with the deck's surface. As a result, there is no need for time consuming removal and replacement of the Pod ConnectorT between missions. In addition, the watertight seal prevents thread corrosion and water freezing on contacts, thereby ensuring reliable attachment. Pod ConnectorT variants include one for supplying power and data and another for transferring fluid and gas. The Pod ConnectorT accelerates mission module installation and reduces logistical overhead by rarely requiring replacement. Working with our partner, Lockheed Martin, we have devised an optimal layout for Pod ConnectorT arrays in each LCS zone. This configuration is designed to maximize the effectiveness of existing and future sensor, vehicle, and weapon modules including the Spartan Unmanned Surface Vehicle (USV), Long-term Mine Reconnaissance System (LMRS) Unmanned Underwater Vehicles (UUV), and Phalanx Close-In Weapon System (CIWS). |

| Title: | Selectable Error-Free Analog and Digital Operations Grid Connector |
| Abstract: | Most deck-mounted hardware is permanently attached to the ship's structure, so ships cannot be easily reconfigured to fill gaps in a conventional naval force structure. This means that ships cannot be leveraged when naval forces are scarce in a certain location, or for simultaneous conflicts in widely separated theaters. A multifunctional, rugged, easy-to-use plug-and-play connector will directly address this problem. To meet this U.S. Navy need, Physical Optics Corporation (POC) proposes to develop a new Selectable Error-free Analog and Digital Operations Grid (SEADOG) connector. The SEADOG connector features: (1) a novel 360 degree blind connection, ensuring that hardware can be attached quickly and easily to a ship's structure in any weather or sea state; (2) rapid self-correcting connections for both power and data, ensuring seamless multimedia communication, uninterrupted video throughput, reliable sensor data, and real-time targeting information even within crowded shipboard digital domains; and (3) a self-actuating environmental seal protecting sensitive mechanical and electrical components from the harsh marine environment. In Phase I POC will develop, fabricate, and test a SEADOG connector model to demonstrate feasibility of the concept. In Phase II an optimized and rugged engineering prototype will be built that will be tested under laboratory test conditions. |

| Title: | Algorithms for Rapid and Accurate Depth Localization of Targets for Mine Avoidance |
| Abstract: | The US Navy's new DD(X) destroyer currently under design features amongst its extensive sensor suite an innovative dual (high frequency and mid-frequency) frequency, active bow sonar. One of the primary missions of the high frequency (HF) component of the bow-sonar will be in-stride mine avoidance. Advanced signal processing algorithms, developed for predecessor sonars aboard modern US submarines, allow high-resolution localization (range, depth and relative azimuth) of mine-like objects. However, the performance of these algorithms is degraded under multipath conditions typical of shallow water (<200m) environments. Here we propose to investigate, develop, demonstrate and implement modifications to the existing signal processing sequence to improve the sonar's mine-hunting capabilities in refractive, multipath environments. These modifications will be implemented in a robust, post-monopulse correlated-field-processing algorithm. The proposed algorithm will endeavor to simultaneously estimate both target location and relevant environmental parameters by comparing the beam-time structure of detections on both the real and imaginary parts of the complex monopulse output to efficiently computed, model estimations of the same. Multi-ping trends in beam-time space of the measured and modeled multipath echo differences will facilitate efficient corrections to the assumed sound speed structure and bathymetry via low order empirical and analytical parametric perturbations |

| Abstract: | This work proposes to develop an efficient algorithm for rapid and accurate depth localization of mine-like targets in shallow water environments where both direct and multi-path wave propagation exists. The proposed algorithm is an extension of an existing table look-up approach for direct path refraction correction, which has been implemented in real time software at the Atlantic Undersea Test and Evaluation Center (AUTEC) for improved depth localization of targets on range. In this approach, the major computational effort associated with the time-consuming, trial-and-error ray tracing to determine the actual refracted path for each eigen ray (either direct or multi-path) between the emitted pulse from the ship's sonar and the target's reflected position, is conducted prior to implementing the real-time localization based on sound velocity and travel time. The result of this a priori computation is termed the effective sound velocity between two positions for the specific ocean environment (SVP and bathymetry) and is stored in tables in terms of various depths and depression/elevation angles. During the real-time localization process, only simple interpolations are required to obtain the effective sound velocity (which is significantly different from the true sound velocity at various depth locations) between the ship and target positions. |

| Title: | Advanced Detection, Classification, and Avoidance Toolkit (ADCAT) |
| Abstract: | The need for autonomous unmanned vehicles is becoming more evident. Unmanned surface vehicles (USVs) provide benefits ranging from manpower reduction and force multiplication, to performing missions too dangerous for manned platforms. One of the most critical challenges is the avoidance of obstacles. 21st Century Systems, Incorporated (21CSI) is in the right place at the right time with regard to this topic. Through various SBIR projects for the Navy and other services and agencies, we have developed and refined many of the pieces required to meet this challenge and are pleased to propose to address it. Through our considerable decision support expertise gleaned from development projects on behalf of many DOD agencies and melded with a state-of-the-art image processing technique, we propose to provide state-of-the-art object detection and classification for situation awareness and object avoidance. We call our concept the Advanced Detection, Classification, and Avoidance Toolkit (ADCAT). The general nature of our proposed solution and its expected effectiveness will make it applicable to a wide range of FNC unmanned vehicles. The ADCAT enabling technology, utilizing a computationally efficient algorithm that is robust with respect to geometrical transformations and spatial and temporal variations, will permit object detection and classification for unmanned vehicles. |

| Title: | Object Avoidance for Unmanned Surface Vehicles (USVs) |
| Abstract: | Daniel H. Wagner Associates, Inc. will develop an Object Avoidance for Unmanned Surface Vehicles (OAUSV) system that processes all available data, dynamically generates a Tactical Picture, an optimal route, and an object avoidance plan, and provides this information to the Unmanned Surface Vehicle (USV) control system and its operators. A key capability provided by OAUSV will be the ability to fuse data obtained by off-board systems (e.g., other ship's/aircraft/UVs' organic systems, Route Surveys, MCM systems) with own-USV data in real-time. In addition, we will utilize the contact data fusion and environmental data fusion algorithms developed in our Commander's Estimate of the Situation Tactical Decision Aid (CESTDA) and Current, Wind, and Wave Data Fusion (CWWDF) projects for ONR to determine a recommended route for the USV that minimizes ship vulnerability. As shown in our Cooperative Organic Mine Defense (COMID) work, the ability to utilize non-own-USV data will significantly improves the ability of the USV to maneuver around potentially threatening objects and dramatically reduces the number of false alarms. The primary algorithmic techniques that will be utilized in OAUSV are non-Gaussian and multiple hypothesis data registration and fusion, non-Gaussian optimization, and Bayesian inferential reasoning. |

| Title: | SmartAvoidT - A Portable, Scalable Object Avoidance Solution for all Day/Night/Weather/Smoke Environments |
| Abstract: | The primary objective of this SBIR effort is to develop a novel object avoidance algorithm dubbed SmartAvoidT. Unmanned vehicles of all types are faced with the common challenge of avoiding objects in the path of the unmanned vehicle. Until a robust, affordable object avoidance solution is provided, true autonomous operation on unmanned vehicles cannot be performed. Genex Technologies, Inc., a 3D and high-speed image processing company proposes to develop and integrate an object avoidance system for USVs. Our focus is to develop a novel object avoidance algorithm called SmartAvoidT that extracts multiple objects/targets out of video/imagery data, establishes individual tracks for each object and maps a path around each object to avoid collisions. The algorithm will then integrate with navigation systems to change course to avoid each object, continuously updating the "mapped" route. The primary innovation of our proposed SmartAvoidT algorithm is the adaptation of a multi-state-machine framework that uses a variety of object detection and target tracking methods to create robust inter-object `awareness' in high noise and cluttered (sea) environments. Our goal is to develop a reliable object avoidance algorithm that can provide robust location and history of the movement of multiple objects in real time within any imagery data (i.e. visible, near infrared, infrared, image intensified (I2), Ultra-Wideband (UWB), or any imagery yielding multiple targets within a stationary or moving background). |

| Title: | Adaptive and Intelligent Object Avoidance for Unmanned Surface Vehicles (USVs) |
| Abstract: | Automated object avoidance for Unmanned Surface Vehicle (USV) for both Navy (and DoD in general) and commercial applications has been the subject of much research and development over the past decades. The creation of a set of robust software tools for fully automated detection, classification/recognition and tracking of objects is vital in the development of an avoidance system for USVs. Without such tools the Navy operation of USV will require the existence of the man-in-the-loop (MITL) navigation. A multitude of current and future research and developments support the potential values and needs of autonomous systems. The use of truly autonomous USVs has been hampered by a lack of sophisticated and resource efficient obstacle avoidance systems. Current approaches have focused on either expensive active sensor systems or inferential processing techniques that are computationally intensive. In this proposal, UtopiaCompression and Defense Research Associate (UC/DRA) present an adaptive and intelligent system concept, using innovative algorithms in computer vision, mobile robotics, and computational intelligence, in particular Machine Learning (ML), which will facilitate true autonomous USV operations by providing a real-time, end-to-end solution tailored to Navy's sensor data and mission requirements using inexpensive imaging sensors and modest computational resources. |

| Title: | Multi-purpose sensor module for valve control |
| Abstract: | As part of the DDX and future Navy automated ship requirements, systems that were once controlled manually must now be controlled automatically or remotely. Control of mechanical systems requires feedback from sensors located at the device. Luna proposes to develop a multi-purpose sensor module for valve control and automation on board Navy ships. The module will be capable of either wired or wireless communication. Using battery powered wireless technology; this system is easily retrofitted onto existing ships, not requiring any new cable runs. Sensor data is transmitted to an application specific node for use in a control system, or to an Ethernet type node to make data available to multiple shipboard systems. On valves that are electrically controlled, the sensor module will have the option of wired power to prevent the need for periodic battery changes. The sensor will also have the capability of 0-10V or 4/20 milliamp output via a connector on the housing for systems that require wired communications. Standard pressure sensors will be used to interface with the module for measurement at any common pressure range. This same platform can also be used to measure parameters such as temperature, strain, and acceleration for other health monitoring applications. |

| Title: | Embedded Pressure Sensors for Automation and Control of Fluid Valves |
| Abstract: | The US Navy continues to research and develop advanced automation technologies to reduce the manning required to operate the next generation of combatants, without compromising platform survivability. One of the most manpower-intensive activities is damage control, during which time critical systems are shut down or re-routed to keep the ship operational. Sailors have typically been the only means of assessing and reacting to damage to a ship system1. For many systems, rapidly isolating damage and preventing loss of line media are critical to continued ship operation. Automated distributed control systems promise to greatly reduce reaction time and significantly reduce the numbers of sailors required during damage control operations by utilizing the following technology: ú Smart sensors to determine line pressure and fluid flow ú Smart valves to isolate damage Smart valves are now available that include controllers capable of communicating with sensors and other smart valves, each commonly referred to as "nodes" in the system. Depending on its location in the system, each smart valve is programmed to respond to information sent to it by other nodes, such as line pressure, fluid temperature, fluid flow, and whether other valves are open or closed. The primary Phase I Technical Objective is to assess the state-of-the-art in pressure and flow sensors and their applicability to smart fluid systems on Navy ships. From this information a recommendation will be made regarding the best available sensors that will meet the needs of the Navy. Marotta proposes to use a 3-step approach in order to achieve the stated Technical Objective. The first step of this SBIR will be to conduct an exhaustive survey of the market for pressure and flow sensors. The second step will be to select one or more of the most promising products or technologies and recommend design changes as required for the Navy ship environment. The final step will be to incorporate these sensors into a smart valve system, using LonWorks or other field bus, to provide the information necessary to monitor, troubleshoot and reroute the system around any damaged or non-functioning sections. |

| Title: | Embedded Smart Pressure Sensors for Automation and Control of Fluid Valves |
| Abstract: | The objective of our proposal is to demonstrate the feasibility of producing a low profile, small size, all stainless steel pressure sensors which is suitable for the automation control of fluidic valve (smart valve). This Phase I project will develop novel capacitive strain gage and eventually an all stainless steel pressure sensor will be developed using this new strain gage. Capacitive sensing is inherently high sensitive and near zero temperature effects. All stainless steel pressure design is rugged and suitable for harsh environment, such as, in salt water, hydraulic oil, lube oil, and even in heat exchangers. The strain gage will be batch fabricated using micromachining method, thus low cost. A commercially available very low power consumption wireless network will also be studied in Phase I. In Phase II, an ultra-miniature and low power consumption wireless network will be developed and will be incorporated with the newly design pressure sensor to form a complete package for automatic control of fluidic valve. |

| Title: | A MEMS-Based Sensor for Automation and Control of Fluid Valves |
| Abstract: | In this program, Orbital Research Inc. will enhance its current embedded pressure sensor technology, which previously has been demonstrated for sensing in-situ engine combustion events, for the automation and control of shipboard fluid valves. Precise control of high pressure fluidic systems is currently accomplished using high performance control valves. Performance of these valves can be improved by coupling them with local pressure sensors to allow feedback control. Adding data feedback to damage control, propulsion and other shipboard systems will enable improved safety, greater efficiency and better system survivability while requiring less manning. This proposal presents an innovative MEMS-based sensor system which exhibits very high sensitivity allowing it to be small and non-intrusive. Its material composition makes it very robust, chemically resistant, and survivable in a variety of environments, including salt water, lube oil, and hydraulic fluid. The MEMS fabrication technology makes it inherently inexpensive and allows flexibility in packaging to accommodate communication options. In this Phase I program, a sensor will be designed, and fabricated for laboratory testing to ensure robustness and prove the feasibility. The Phase II program will build on the Phase I through detailed design optimization including extensive full-scale prototype testing in a working fluid system. At the conclusion of this successful SBIR program, Orbital Research anticipates having a system ready for Phase III field evaluation on a future combatant platform such as DD(X). |

| Title: | Embedded Pressure Sensors for Automation and Control of Fluid Valves |
| Abstract: | The new pressure sensor/transmitter technology for marine flow valves represents enormous advantages over existing marine pressure measurement devices. The new technology would meet virtually all the U.S. Navy needs in flow pressure/rate sensing at a fraction of the cost of what it presently costs the Navy to purchase. These low cost "pliable" sensors can be directly integrated in piping and valving adjacent to the flow of fluids or gasses. The technology offers significantly more accurate sensor measurements than are presently available with `pressure diaphragm' or other resistive sensor related techniques. The manufacture is a low cost production process that can easily be geared from few to mass output levels. The devices themselves are immune to temperature drift and will be available in small/very low profile packaging size that is pliable and can be directly attached to the interior walls of pipes and fittings. |

| Title: | Aerogel insulation blankets for shipboard noise suppression |
| Abstract: | High noise levels on aircraft carriers from onboard flight operations impart tremendous implications, including miscommunication during combat and training, reduced crew combat effectiveness from stress and fatigue, and medical expenses from hearing damage. To mitigate the cost and safety concerns, Office of the Chief of Naval Operations Occupational Safety and Health Requirements stipulate that new ship designs incorporate acoustical treatments so that the equivalent noise level at watchstander stations is less than 84 dBA. To accomplish this objective, the Navy wants to develop new sound insulation which surpasses current state-of-the-art materials for passive noise reduction. Prior efforts have shown that aerogel insulation blankets, developed for thermal purposes only, have potential to absorb sound. On the proposed effort, Aspen Aerogels, Inc. will optimize those aerogel blanket materials specifically for acoustic noise suppression. Aspen will vary chemical composition, density, and pore size, as well as include hybrid material solutions. Phase II will scale up development and perform full testing needed to qualify the system for shipboard use. Overall, the proposed aerogel insulation will be cost effective, light-weight, and able to satisfy thermal, smoke, and fire barrier requirements. |

| Abstract: | The objective is to develop a new class of insulation coating that simultaneously targets noise, fire and condensation. A single coating which can fulfill all the requirements would be the ideal solution (Design A). Recently, QS completed R&D on a novel viscoelastic polymer for use in construction that provides superior sound damping along with fire protection in a single polymer blend. This is now in commercial use. Some of this technology, combined with ceramic microspheres, can be leveraged into a single coating. This one-component system, referred to as Design A, will be investigated as part of Phase 1. Alternatively, a lower risk Design B two-component coating system will also be investigated. The top component will be a thermal insulating coating consisting of microscopic air-filled ceramic and/or silicon microspheres to provide a fire, thermal insulation and condensation barrier. The bottom component will be QuietShip to damp noise and vibration. QS (and predecessor company) has been shipping acoustic damping viscoelastic polymer technologies for 12 years. It is now executing a project on the X-Craft using the same base polymer slated for the system. QS is confident that it will provide a breakthrough material to Navy as a result of this SBIR. |

| Title: | Acoustic, Thermal and Fire Insulation System |
| Abstract: | In recent years, significant strides have vastly improved the potential for spray on insulation systems that will help to abate airborne noise on Surface Ships. The optimal insulation will provide high acoustic absorption, airborne transmission loss and structural damping along with the requisite thermal/fire/condensation protection. Our objective is to exhibit improved acoustic characteristics through a liquid ceramic thermal insulation that provides NAVSEA approved condensation control. Combine this product with a tested fire retardant product that also displays damping capabilities. These products will produce a multi-modal or composite layered liquid applied barrier. This coating combination is safe, light weight and produces very little smoke. The concept will use proven ceramic micro-sphere technology that we have developed and designed over a 14 year period. The blending of micro spheres in a safe, light weight waterborne matrix has been accepted for use by industry and manufacturing in a wide array of circumstances. TECH 21 research will investigate how these products can be combined for maximum results. The conclusion will yield a method of blending and installation that will reduce handling, weight and installation costs. We will explore the incorporation of this system into the N98-092 JERICHO program and SNAME's Design Guide 3.37. |

| Title: | Active Noise Reduction Technology |
| Abstract: | The proposed effort will actively reduce noise from flight operations at watchstander stations below the flight deck to levels that do not require hearing protection. Long-term hearing loss of personnel is projected to cost the Navy on the order of $12.6 billion over a 30 year retirement period. Active noise reduction (ANR) has long been known as the best method of controlling low-frequency noise but has been limited by available technologies. Recent developments in modern control methods and microprocessors have made active noise reduction a practical, realizable solution for controlling low-frequency noise. Etrema Products, Inc. proposes to implement an ANR system to reduce noise levels from shipboard flight operations by >20 dBA over the frequency range from 50-800 Hz. The proposed approach uses a combination of active structural acoustic control and active noise cancellation by vibrating ship bulkheads and/or speaker panels to actively control noise in ship compartments using the magnetostrictive material, TERFENOL-D. The Phase I effort will be to generate a design concept, demonstrate its feasibility through modeling, and develop a concept validation plan. If successful, the proposed work will reduce costs to the Navy of long-term hearing loss and other detrimental effects of excessive noise exposure. |

| Title: | Active Noise Reduction Technology |
| Abstract: | Noise levels in crew compartments below the flight decks on Navy ships during flight operations have traditionally been extremely noisy due to jet engine noise as well as launch machinery transients. Levels exceed Navy desired levels by over 10 dB. Current state of the art materials do not work well at low frequencies. SSC proposes to develop an active noise solution that consists of a modular, fully integrated smart material that can be applied to the interior compartments of ships. The smart acoustic panel will reduce radiating noise by employing advanced smart materials such as polyvinylidene fluouride (PVDF) and lead zirconate titanate (PZT) actuation materials, embedded MEMs based acoustic and vibration sensors, and polyurethane foam for passive vibration absorption. A method to use smart acoustic materials to provide local noise control of manned spaces will also be investigated if global control proves to be unfeasible. |

The proposed tools interface with commercial off-the-shelf products and are designed to streamline the HCI design and development process without forcing DD(X) personnel to significantly change the process they currently follow. The approach centers on working closely with the ship system integrator industry to form project execution and implementation teams; obtaining input from experienced individuals to focus on developing software technologies that promote commonality within the Total Ship Computing Environment (TSCE), thus adhering to the Navy's proposed Open Architecture Computing Environment guidelines and reducing lifecycle costs. Harmonia has identified six DD(X) engineering problem areas and possible UIML-based tools to address them. During Phase I Harmonia will define requirements, identify potential risks, conduct selected prototyping activities, and assess the commercial viability of each technology to determine which have the most potential benefit for the DD(X) program and should thus be prototyped in Phase II |

| Abstract: | RLW proposes to design and demonstrate a TSCE-I compliant "micro" Distributed Adaptation Processor (DAP) by incorporating a modified TSCE client into its SxNAP(TM) family of products. This will provide a family of "Small, low cost peripheral data collection and legacy system interface" options for DD(X) and other DoD and commercial platforms. The SxNAP family has been developed over the last five years to provide a hardware/software platform to enable connection of any analog sensor to any network. The SxNAP devices provide signal conditioning and sensor power, local processing to apply algorithms and logic to sensor data (reduce bandwidth and enable limited local closed-loop control), and communications to manage the network interface and format the data. The family spans multi-sensor/high processing power applications for vibration analysis to single sensor/low processing power applications for monitoring distributed parameter values (temperature, pressure). Our efforts to date have focused on an XML interface over wired and wireless (802.11b/g) TCP/IP networks, but the platform has been designed to accommodate any network interface. This project will adapt and port the TSCE Client onto a low-cost microprocessor/microcontroller platform - the SxNAP Network Processor. |

| Title: | Stable Platform Module for Ships |
| Abstract: | There exists many potential applications for stable platform technology on Navy as well as commercial vessels. One such application is launching and recovering UAVs and VTUAVs on ships at sea. Without a stable launch and recovery platform that eliminates ship accelerations, operation of the unmanned aerial vehicles from ships is difficult. Although stabilization systems for orientational degrees of freedom are common on ships (e.g., consider fire control systems and stabilized antennas), systems that provide stabilization for both orientation and large changes in position are not. We propose to develop a concept that can provide full stabilization (i.e., in both position and orientation) that would greatly facilitate a UAV and VTUAV operation on ships and that can be adapted to other applications such as at-sea transfer of cargo and personnel. A dynamic simulation of the proposed stable platform module will be developed and candidate COTS hardware and suitable low-level control architectures will be identified. System requirements will be refined and critical derived requirements, including ship motion sensing, will be established. The results of the phase I effort will allow for a smooth transition to the hardware prototype development for phase II. |

| Abstract: | SatCon proposes a stable platform module for the launch and recovery of UAVs from the decks of Navy Ships. This platform will accommodate large amplitude motions in roll, pitch and heave enabling wide spread use of UAV systems on smaller Navy ships over a wide range of sea sates and vessel speeds. The platform will utilize an innovative folding actuator system that allows large vertical displacements while providing for a low profile installation without intruding below the deck. The fully electric actuator system will require very little maintenance reducing operating cost and manning requirements. In Phase I we will assess launch and recovery requirements for a variety of UAV/UAS, deck motion characteristics of Navy and commercial ships and determine requirements for platform size, amplitudes of actuator motion, and necessary control bandwidths. Also in Phase one a preliminary design of the prototype Stable Platform Module will be generated. Detailed structural analysis and dynamic simulations will be performed in a Phase I option. A full-scale prototype will build and evaluated in the subsequent Phase II program. |
