ARMY
PROPOSAL SUBMITTAL
The United States Army Research Office (ARO), reporting to the Army Research Laboratory (ARL) manages the Army’s Small Business Technology Transfer (STTR) Program. The following pages list topics that have been approved for the fiscal year 2007 STTR program. Proposals addressing these areas will be accepted for consideration if they are received no later than the closing date and hour of this solicitation.
The Army anticipates funding sufficient to award one or two STTR Phase I contracts to small businesses with their partner research institutions in each topic area. Awards will be made on the basis of technical evaluations using the criteria contained in the solicitation, within the bounds of STTR funds available to the Army. If no proposals within a given area merit support relative to those in other areas, the Army will not award any contracts for that topic. Phase I contracts are limited to a maximum of $100,000 over a period not to exceed six months.
The Army requires that your entire proposal (consisting of Proposal Cover Sheets, the full Technical Proposal, Cost Proposal-using the template provided and Company Commercialization Report) must be submitted electronically through the DoD-wide SBIR/STTR Proposal Submission Website (http://www.dodsbir.net/submission). A hardcopy is NOT required. Hand or electronic signature on the proposal is also NOT required.
The DoD-wide SBIR/STTR Proposal Submission system (available at http://www.dodsbir.net/submission) will lead you through the preparation and submission of your proposal. Refer to section 3.0 at the front of this solicitation for detailed instructions on Phase I proposal format. You must include a Company Commercialization Report as part of each proposal you submit; however, it does not count against the proposal page limit. If you have not updated your commercialization information in the past year, or need to review a copy of your report, visit the DoD SBIR/STTR Proposal Submission site. Please note that improper handling of the Commercialization Report may result in the proposal being substantially delayed and that information provided may have a direct impact on the review of the proposal. Refer to section 3.5d at the front of this solicitation for detailed instructions on the Company Commercialization Report.
If you collaborate with a university, please highlight the research that they are doing and verify that the work is FUNDAMENTAL RESEARCH.
Be reminded that if your proposal is selected for award, the technical abstract and discussion of anticipated benefits will be publicly released on the Internet therefore, do not include proprietary or classified information in these sections. DoD will not accept classified proposals for the STTR Program. Note also that the DoD web site contains timely information on firm, award, and abstract data for all DoD SBIR/STTR Phase I and II awards going back several years. This information can be viewed on the DoD SBIR/STTR Awards Search website at www.dodsbir.net/awards.
Based upon progress achieved under a Phase I contract, utilizing the criteria in Section 4.3, a firm may be invited to submit a Phase II proposal (with the exception of Fast Track Phase II proposals – see Section 4.5 of this solicitation). Phase II proposals should be structured as follows: the first 10-12 months (base effort) should be approximately $375,000; the second 10-12 months of funding should also be approximately $375,000. The entire Phase II effort should generally not exceed $750,000. Contract structure for the Phase II contract is at the discretion of the Army’s Contracting Officer after negotiations with the small business.
The Army does not issue interim or option funding between STTR phase I and II efforts, but will provide accelerated phase II proposal evaluation and contracting for projects that qualify for fast-track status.
Army STTR Contracts may be fully funded or funded using options or incremental funding.
CONTRACTOR MANPOWER REPORTING (CMR) (Note: Applicable only to U.S. Army issued STTR contracts)
Accounting for Contract Services, otherwise known as Contractor Manpower Reporting (CMR), is a Department of Defense Business Initiative Council (BIC) sponsored program to obtain better visibility of the contractor service workforce. This reporting requirement applies to all STTR contracts issued by an Army Contracting Office.
Offerors are instructed to include an estimate for the cost of complying with CMR as part of the cost proposal for Phase I ($100,000 max) and Phase II ($750,000 max), under “CMR Compliance” in Other Direct Costs. This is an estimated total cost (if any) that would be incurred to comply with the CMR requirement. Only proposals that receive an award will be required to deliver CMR reporting, i.e. if the proposal is selected and an award is made, the contract will include a deliverable for CMR.
To date, there has been a wide range of estimated costs for CMR. While most final negotiated costs have been minimal, there appears to be some higher cost estimates that can often be attributed to misunderstanding the requirement. The STTR program desires for the Government to pay a fair and reasonable price. This technical analysis is intended to help determine this fair and reasonable price for CMR as it applies to STTR contracts.
· The Office of the Assistant Secretary of the Army (Manpower & Reserve Affairs) operates and maintains the secure CMR System. The CMR website is located here: https://contractormanpower.army.pentagon.mil/.
· The CMR requirement consists of the following 13 items, which are located within the contract document, the contractor's existing cost accounting system (i.e. estimated direct labor hours, estimated direct labor dollars), or obtained from the contracting officer representative:
(1) Contracting Office, Contracting Officer, Contracting Officer's Technical Representative;
(2) Contract number, including task and delivery order number;
(3) Beginning and ending dates covered by reporting period;
(4) Contractor name, address, phone number, e-mail address, identity of contractor employee entering data;
(5) Estimated direct labor hours (including sub-contractors);
(6) Estimated direct labor dollars paid this reporting period (including sub-contractors);
(7) Total payments (including sub-contractors);
(8) Predominant Federal Service Code (FSC) reflecting services provided by contractor (and separate predominant FSC for each sub-contractor if different);
(9) Estimated data collection cost;
(10) Organizational title associated with the Unit Identification Code (UIC) for the Army Requiring Activity (The Army Requiring Activity is responsible for providing the contractor with its UIC for the purposes of reporting this information);
(11) Locations where contractor and sub-contractors perform the work (specified by zip code in the United States and nearest city, country, when in an overseas location, using standardized nomenclature provided on website);
(12) Presence of deployment or contingency contract language; and
(13) Number of contractor and sub-contractor employees deployed in theater this reporting period (by country).
· The reporting period will be the period of performance not to exceed 12 months ending September 30 of each government fiscal year and must be reported by 31 October of each calendar year.
· According to the required CMR contract language, the contractor may use a direct XML data transfer to the Contractor Manpower Reporting System database server or fill in the fields on the Government website. The CMR website also has a no-cost CMR XML Converter Tool.
· The CMR FAQ explains that a fair and reasonable price for CMR should not exceed 20 hours per contractor. Please note that this charge is PER CONTRACTOR not PER CONTRACT, for an optional one time set up of the XML schema to upload the data to the server from the contractor's payroll systems automatically. This is not a required technical approach for compliance with this requirement, nor is it likely the most economical for small businesses. If this is the chosen approach, the CMR FAQ goes on to explain that this is a ONE TIME CHARGE, and there should be no direct charge for recurring reporting. This would exclude charging for any future Government contract or to charge against the current STTR contract if the one time set up of XML was previously funded in a prior Government contract.
· Given the small size of our STTR contracts and companies, it is our opinion that the modification of contractor payroll systems for automatic XML data transfer is not in the best interest of the Government. CMR is an annual reporting requirement that can be achieved through multiple means to include manual entry, MS Excel spreadsheet development, or use of the free Government XML converter tool. The annual reporting should take less than a few hours annually by an administrative level employee. Depending on labor rates, we would expect the total annual cost for STTR companies to not exceed $500 annually, or to be included in overhead rates.

Army STTR 07 Topic Descriptions
A07-T001 TITLE: Long life, low power, multicell battery
TECHNOLOGY AREAS: Ground/Sea Vehicles, Electronics
The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services. Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 3.5.b.(7) of the solicitation.
OBJECTIVE: Develop a low-power miniature (coin cell or similar) battery with a 30-plus year operational lifespan that is suitable for battery-backed static random access memory (SRAM) and environmentally friendly with minimal disposal issues.
DESCRIPTION: This effort will focus on identifying new and innovative multi-cell battery technologies suitable for powering battery-backup, low power static random access memories (SRAM). The new multi-cell battery shall be a low power miniature (coin cell or similar) battery with a 30 plus year operational lifespan. The new battery technology shall not incorporate toxic metals like cadmium, lead, mercury, etc. and minimize the amount of hazardous materials. New battery technology shall not be constructed from energetic materials that may be explosive under certain conditions. New battery shall not use radioactive materials. New battery technology shall not use high temperature thermal battery technologies. The goal is to create an environmentally friendly battery with minimal disposal issues. The new battery technology will be suitable for battery-backed SRAM memories and SRAM memories for bitstream keys inside field programmable gate arrays (FPGA).
Current battery technology has focused on extending the life of the battery. An alternate approach would be to combine multiple cells inside a battery. Each cell is initially in an inert state. After activation, a cell will operate as a traditional low power battery-backup for low power SRAM typically used to store FPGA bitstream keys. A low activation energy of less than 1% of each cell’s capacity is desired. The time to activate the cell should be less than 1 hour.
In concept, when a cell is approaching the end-of-life, another cell is activated, effectively extending the life of the multi-cell battery. In a four cell battery, with 5 years of operational life per cell; a 20 year lifetime is possible. Minimum lifetime for each cell, once activated, under an average 0.25/n mW load, is one month (approximately 0.2/n watt-hours) where n is the number of cells ( n >=1 ) inside the battery. The weighting, for evaluating the technical merits of the new and innovative battery technology, will be battery life (2), nontoxic, non-hazardous materials (1), and disposal (1).
PHASE I: Contractor will analyze and design a novel concept battery cell. The new battery technology shall not incorporate hazardous or toxic materials like cadmium, lead, mercury, etc. New battery technology shall not be constructed from energetic materials that may be explosive under certain conditions. New battery shall not use radioactive materials. New battery technology shall not use high temperature thermal battery technologies. The goal is to create an environmentally friendly battery with minimal disposal issues.
While in an inert state, the battery has a shelf life of 25 plus years at 25 degrees Celsius. Nominal operating temperature range with slightly reduced performance: -10 degrees Celsius to +40 degrees Celsius. Operation over the industrial temperature range of -40 to +85 degrees Celsius with reduced performance is desired. Battery operation with reduced performance over part or all of the full military temperature range of -50 degrees Celsius to +125 degrees Celsius will be considered a plus.
Upon activation, a cell will provide power for a battery-backed SRAM memory for 0.1 (lower limit) to 5 plus years at 25 degrees Celsius. The energy for activation should be less than 10 % of each individual cell’s energy capacity with a goal of less than 1 %. Contractor shall perform an accelerated aging test on the cell to determine the shelf life in the inert, inactivated state and the operational lifespan of the cell for a simulated SRAM battery back-up memory.
The requirement for the new battery is to operate over the industrial temperature range of -40 to +85 degrees Celsius. We are also interested in the potential performance of the battery over the full military temperature range of -50 to +125 degrees C. The contractor shall conduct an accelerated aging test over the industrial temperature range of -40 to +85 C. Operation over a wider temperature range up to the full military temperature range of -50 to +125 C will be considered a plus.
Contractor shall provide a report describing accelerated aging test and battery lifespan for current levels of 0.1 to 10 equivalent loads for a SRAM with at least 256 bit memory capacity.
PHASE II: Contractor shall develop a multi-cell battery based on the technologies from Phase I to create a battery with greater than a 25 year operational lifespan powering a battery backed SRAM at 25 degrees Celsius. Contractor shall have an independent verification and validation (IV&V) to validate the batteries performance over the industrial temperature range of -40 to +85 degrees Celsius and for current levels of 0.1 to 10 equivalent loads for a SRAM with at least 256 bit memory capacity. Operation over a wider temperature range up to the full military temperature range of -50 to +125 C will be considered a plus. Contractor shall provide a report on the IV&V.
PHASE III: Contractor shall team with a prime contractor and commercialize the new battery technology. The contractor is encouraged to team with a defense prime contractor and a traditional commercial corporation to market the technology to both military and commercial end users. Contractor shall provide an IV&V report on accelerated aging tests for a production level battery showing mean battery life as a function of temperature over the industrial temperature range of -40 to +85 degrees Celsius and for current levels of 0.1 to 10 equivalent loads for a SRAM with at least 256 bit memory capacity. Operation over a wider temperature range up to the full military temperature range of -50 to +125 degrees Celsius will be considered a plus. Contractor shall have an independent laboratory test the battery to flight safety requirements of the FAA. Contractor shall provide an independent laboratory report on the battery’s materials and disposal issues. Contractor shall provide a material safety data sheet on battery family.

A07-T002 TITLE: Software Anti-Tamper for Matrix based Algorithms
TECHNOLOGY AREAS: Information Systems
The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services. Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 3.5.b.(7) of the solicitation.
OBJECTIVE: Research objective is to investigate improving software level obfuscation for highly regular matrix based algorithms. A number, of recursive algorithms or adaptive algorithms, consists of an iterative matrix equation W(k+1) = f [W(k)] + other terms where W( ) is a matrix. The highly regular structure makes reverse engineering trivial. Software obfuscation increases the difficulty of reverse engineering software. For matrix equations, there are other options for obfuscation at the algorithm level: similarity transforms, transformations for “sparse” matrix equations, etc. The goal here is to combine iterative matrix equations with clever matrix transformations (possibly time varying transformations) with traditional code obfuscation techniques to improve software anti-tamper for matrix intensive algorithms. Some possible applications for obfuscation at the matrix equation level include: Kalman filtering, least-mean squares (LMS) algorithm, state space control theory, short-term Fourier transform, wavelet signal processing, Gerchberg-Saxton algorithm, and streaming real-time image processing. The contractor is asked to select a matrix intensive algorithm and examine obfuscation at the matrix equation level. Contractor may also select an appropriate function domain(s): time, frequency, time-frequency, space, wavelet, etc.
DESCRIPTION: All U.S. Army Program Executive Offices (PEOs) and Program Managers (PMs) are now charged with executing Army and Department of Defense (DoD) anti-tamper policies in the design and implementation of their systems to afford maximum protection of U.S. technologies, thus providing maximum protection against them being obtained and utilized and/or exploited by foreign adversaries. One area of vulnerability is in the software in a weapons system, where there are many critical technologies that can be compromised. Techniques are now emerging to begin to try to combat this loss of the U.S. technological advantage, but further advances are necessary to provide useful toolsets to the U.S. Army PEOs and PMs for employment in their systems. As AT is a relatively new area of concern, the development of AT techniques is in a somewhat immature state and new ideas are always needed.
The goal of software obfuscation is, through transformations, clever disguise, or restructuring of the program, to make it more difficult to reverse engineer computer software. Army and DoD systems use navigation software where data from several sensors are blended together with a Kalman filter. A Kalman filter is a highly, regular, recursive matrix equation. The structured nature of a Kalman filter makes software obfuscation more difficult. We would like to investigate the possibility of obfuscation at the algorithm level combined with traditional software obfuscation for anti-tamper. The objective section describes some other possible matrix equations for study.
“No technique is invulnerable or even clearly superior to the others in all circumstances; therefore, a mix of protection techniques allows the defense to capitalize on the strengths of each technique while also masking the shortfalls of other techniques.” http://www.stsc.hill.af.mil/crosstalk/2004/11/0411atallah.html.
It should also be noted, that the use of off-the-shelf components in a system can seriously compromise an AT design due to the ready availability of open-source documentation. The effort should therefore focus on denying an adversary access to enough information to begin such a data search. The technologies/techniques developed should inhibit an adversary’s exploitation and/or reverse engineering effort to a point where it will require a significant resource investment to compromise, allowing the U.S. time to advance its own technology or otherwise mitigate the loss. As a result, the U.S. Army can continue to maintain a technological edge in support of its warfighters.
PHASE I: Contractor shall select a recursive or iterative matrix intensive algorithm. Some possible algorithms are presented in the objective section. Contractor shall propose algorithm level obfuscation technique(s) for the selected algorithm. Some potential challenges for obfuscating matrix equations include performance degradation, error propagation, algorithm stability, and convergence issues. Series approximations to matrix and integral equations may lead to difficulties with convergence. A series of obfuscated terms may lead to problems with correctly deciding the appropriate point to truncate series terms. Problems with finite numerical precision may cause convergence and stability problems. Obfuscation of near singular matrices may result in additional convergence and stability problems. Other numerical, convergence issues, and algorithm stability issues may also be present.
Contractor shall propose an algorithm level obfuscation technique(s) for a selected matrix intensive algorithm. Contractor shall provide a report discussing the feasibility of matrix equation level obfuscation and address the limitations imposed by performance degradation, error propagation, approximations, convergence and stability. Contractor shall provide an estimate, based on his past software anti-tamper knowledge and experience, of the level of anti-tamper protection provided by the proposed matrix algorithm obfuscation concepts.
PHASE II: Contractor shall develop the concepts from Phase I into a functional prototype. Contractor shall provide a report discussing numerical, convergence, and stability issues for the matrix algorithm obfuscation. Contractor shall describe conditions where the matrix level obfuscation provides good convergence and stability. Contractor shall also describe conditions where convergence and stability are poor. Contractor shall combine matrix level obfuscation with tradition software obfuscation techniques.
Contractor shall demonstrate matrix algorithm obfuscation and software obfuscation running on an embedded computer with an operating system. Contractor shall have an independent verification and validation (IV&V) performed to test the anti-tamper/anti-reverse engineering provided by the matrix algorithm level obfuscation and traditional software obfuscation. Contractor shall provide a detailed IV&V report of the anti-tamper/anti-reverse engineering provided by the matrix algorithm level obfuscation and software obfuscation. Contractor shall provide a detailed report(s) describing functionality of the anti-tamper tool.
PHASE III: Contractor shall develop a production grade matrix algorithm obfuscation and traditional software obfuscation tool. Contractor is encourage to team with a prime contractor to apply the new obfuscation technology to a current production level system. Contractor is encourage to consider a version of the obfuscation tool for Homeland Security applications.
Contractor shall demonstrate matrix algorithm obfuscation and software obfuscation running on an embedded computer with an operating system.

Contractor shall provide a detailed IV&V report of the anti-tamper/anti-reverse engineering provided by the matrix algorithm obfuscation and software obfuscation.

A07-T003 TITLE: Modular and Authorable Intelligent Tutoring System for Immersive Scenario-Based Training
TECHNOLOGY AREAS: Human Systems
OBJECTIVE: To develop an intelligent tutoring system that could be linked with multiple immersive scenario-based training systems and could be updated by a person without specialized computer experience. The system would monitor trainee performance, provide targeted instructional feedback, and evaluate how well the trainee performed during a training scenario based on training objectives.
DESCRIPTION: Scenario-based training games are currently being used in the Army for a broad range of training domains (e.g., military tactics, support and stability operations, weapons operation, and language training). The research indicates that effectiveness of these training tools is currently mixed (Beal, 2005; Hays, 2005). One reason why training games may not be living up to the hype is that the “instructor” functions of training environments are not regularly included as part of the system (Hays 2005; Belanich, Mullin, Dressel, 2004; Bloom, 1984). One goal of this project is to develop a modular intelligent tutoring system that could be linked to different Army-based training games in order to provide the needed instructor functionality that is currently lacking in many game-based training systems.
For a modular ITS to work appropriately, it would need to exchange data with multiple scenario-based training platforms. The data coming from the training platform would indicate the state of the scenario and provide a low-level depiction of trainee performance. The ITS would use this data to develop a high-level understanding of trainee performance as compared to a model of the training domain. Data going to the training platform would include data to modify the scenario to meet the instructional need of the trainee, which would include instructional feedback.
For scenario-based training systems to be useful to a rapidly evolving military, they need to be easily authorable to keep up with the ever-changing current operating environment. This flexibility needs to be provided to the instructors who implement these types of training systems so they can adequately match the scenario content with the appropriate training objectives (Ainsworth & Fleming, 2006). Therefore, a second goal of this project is to develop an ITS that can be easily authorable by a typical instructor (i.e., person without highly specialized computer skills).
Intelligent tutors are effective training tools, but usually require skilled personnel to develop the system for a particular training platform. An ITS that can be adapted to work with multiple Army-based training platforms and is easily updateable would offer powerful training options to the military that are currently not available. While scenario-based (game-based) training systems have demonstrated limited effectiveness (Hays. 2005), if they are armed with a robust ITS companion to elicit important lessons and training objectives, these training systems may reach their full potential for training today’s Soldiers.
PHASE I: Phase I should determine the feasibility of producing a modular intelligent tutoring system that works with multiple immersive Army scenario-based training systems and covers a range of actions (e.g., speech acts and physical acts). The deliverable for this phase includes a feasibility study with specific recommendations for the system to be developed during the Phase II effort.
PHASE II: In Phase II, the findings of Phase I should be used to develop a working prototype of the system to be assessed by instructors using immersive Army scenario-based training systems. Integration of the ITS with two different scenario-based training platforms would be considered success.
PHASE III: Ownership of a modular intelligent tutor system that can be used by various scenario-based training systems should position the company well for integrating their system into game-based training programs in use by the military, as well as private and public sectors. Because the system is modular, it could be linked with a variety of scenario-based training systems. The system would also find a receptive market in both the training and educational fields, where scenario-based training systems are growing.

A07-T004 TITLE: DRIVING WISDOM: Web-based Training for Young Adults to Improve Operator Judgments that Mitigate Crash Risk in Privately Owned Vehicles
TECHNOLOGY AREAS: Human Systems
OBJECTIVE: Develop new transformative technologies to improve driver safety. Analyze and develop a knowledge base of driver judgments that balance moderately risky but common hazards with ongoing, transportation requirements; and evaluate web-based, training methods in order to motivate young adults (moderately experienced drivers aged 20 to 35) to learn and apply this information in their daily driving. The tutoring module will tailor instructional feedback to student responses and personal characteristics.
DESCRIPTION: In recent years, between 110 and 130 Soldiers have died annually because of crashes in privately owned vehicles (POV) (https://crc.army.mil/). Therefore, understanding and improving driver safety remains an important Army objective. Driver safety models theorize that risk assessment is critical to driver safety (Evans, 1991, 1993; Jonah, 1986; Deery 1999; Gregersen & Bjurulf, 1996), and empirical data have demonstrated: (a) differences in risk assessment between novice and experienced drivers (Trankle, Gelau & Metker, 1990), and (b) correlations between risk assessment accuracy and POV crash involvement for experienced drivers (Legree, Heffner, Psotka, Martin & Medsker, 2003; Legree, Martin, Medsker & Gregory, 1999). In these research formulations, risk assessment has been conceptualized to include identification, assessment, and reaction to driving hazards and risks. According to these results, drivers who are more likely to be involved in vehicle crashes are less able to detect driving hazards and assess the risk associated with specific hazards, especially those risks involving internal psychological states (e.g., fatigue, stress, illness) as well as poorly-documented external factors (e.g., surface quality, distracting children). Such drivers are less likely to act to mitigate those risks, even when proficient with the mechanics of driving, as are experienced drivers in the targeted age range.
However, reviews of driver education curricula and traffic safety guidance indicate that training programs typically support risk assessment only poorly, and improvements with most driver-training programs have been limited to very specific behaviors (Mayhew & Simpson, 1995; Mayhew & Simpson, 2002). These programs often focus on the mechanics of driving and may address the importance of physical risks (e.g., icy roads), but seldom deal with risks derived from internal states. In fact, research has not fully documented the many conceptual and inherently subtle hazards that influence a driver’s psychological state and are frequently encountered by experienced (rather than novice) drivers between the ages of 20 and 35. Moreover, research has not identified actions that might mitigate the risks associated with these specific hazards. Consequently, driving tutorials could be greatly improved by identifying and teaching this knowledge to populations that are fully versant with the mechanics of driving and capable of responding to physical risks.
This project is intended to address this scientific gap by supporting applied research that:
• Surveys young, experienced drivers (between the ages of 25 and 35) to document frequently encountered driving hazards (including internal states) in sufficient detail to identify actions that proactively avoid or reactively mitigate those risks, while balancing transportation requirements.
• Empirically links expectations regarding those hazards & actions to crash involvement metrics.
• Develops web-based tutorials that effectively teach this knowledge to drivers who are 20 to 35 years old using adaptive simulation technologies, which are commercially available and compliant with the Shareable Content Object Reference Model (SCORM) format.
PHASE I: Phase I should determine the feasibility of using critical incident interviews and resulting surveys to document safety risks that are commonly encountered by young, experienced drivers and identify strategies to mitigate and/or avoid those risks. A variety of inductive procedures, such as Latent Semantic Analyses and Consensus Based Assessment may be considered to analyze these data. The resultant guidance is intended to be practical, balancing travel requirements while minimizing risk. Concurrent with initial efforts to identify safety risks and related strategies, Phase I will design a SCORM compliant modular tutoring system to provide information to students that:
1. Mitigates all risks that are most likely to be experienced by individual students, particularly those based on their internal states and characteristics.
2. Reinforces learning using simulation technologies that emotionally engage students.
The deliverable for this phase includes a detailed experimental study with specific recommendations for the research to be conducted and a working prototype (based on one external risk and two internal risk factors) of the system to be developed during the Phase II effort.
PHASE II: Phase II should expand on Phase I accomplishments to expand the identified risks and actions, while linking understandings of those risks and actions to crash involvement metrics. Phase II will develop web-based modules to effectively teach this information to the target population using intelligent simulation technologies.
PHASE III: Ownership of a web-based driver tutorial that can be used to train hazard recognition and reduce crash risk should position the company well for integrating their product into applications designed to enhance driver safety. The system is envisioned to find a receptive market in private and public sectors oriented towards improving driver safety in young adult populations. These sectors include other military services, student support services for colleges and universities, and the insurance industry.

A07-T005 TITLE: Interband Resonant-Tunneling-Diode (I-RTD) Hybrid Terahertz Oscillator
TECHNOLOGY AREAS: Chemical/Bio Defense
OBJECTIVE: To design, build and demonstrate a novel hybrid terahertz (THz) oscillator that utilizes optical-triggering of an interband resonant-tunneling diode (I-RTD) device to achieve record output power performance (e.g., > 3-10 milliwatts) across broad portions of the THz frequency band (e.g., 300-600 GHz) from an all solid-state design operating at room temperature. Military relevant applications of this new source technology include point and remote monitoring for chemical and biological threat agents; standoff imaging of concealed weapons and explosives; ultra-high speed/frequency data processing and communications; and characterization of bio-molecular based devices and systems.
DESCRIPTION: The technological goal of developing a robust and powerful source of controllable electromagnetic radiation within the so-called THz frequency regime (i.e., often defined as the portion of the submillimeter-wavelength electromagnetic (EM) spectrum between approximately 1 millimeter (300 GHz) and 100 micrometers(3 THz)) remains one of the long-standing grand challenges of high frequency electronics. As is well known, the THz regime spans across the frequency domain from RF electronics (where devices primarily utilize transport mechanisms) to photonics (where devices primarily utilize quantum mechanical state transitions) and challenging engineering problems exist in this quasi-optical "gap" where EM wavelength is on the order of component size. Specifically, fundamental physical factors have severely limited the performance (i.e., power and efficiency) of all traditional devices concepts - i.e., in attempts both to extend upward from the millimeter-wave and to extrapolate down from the far infrared. Due to these basic factors, the solid-state electronics capability at THz frequencies remains somewhat limited from a basic signal source and systems perspective. However, while technology limits persist, there has been a great wave of growing scientific interest in THz-related phenomenon, and this includes many military-relevant applications areas - e.g., THz spectroscopic detection, identification and characterization of biological agents and standoff imaging of concealed weapons and explosives.
Indeed, these high priority defense and security applications within the THz regime, along with the unique potential payoffs to the fundamental sciences, previously motivated the U.S. Army Research Program to make significant investments into a number of novel, high-risk, solid-state oscillator concepts. This has subsequently led to an important recent breakthrough where an interband-tunneling mechanism present in staggered-bandgap resonant tunneling diodes (RTDs) has been shown useful for accessing instability processes at the nanoscale [1]. This is important because it allows for the elimination of certain broad-band design requirements (i.e., prevent unwanted low-frequency modes) that had severely limited output power performance within fundamental RTD oscillators. Furthermore, as a direct result of a long-term research investment by the by U.S. Army Research Office, accurate models for describing the electron transport phenomenon within Interband RTDs (I-RTDs) were developed for the first time [2, 3] and this led to comprehensive theoretical studies [4] of a Hybrid I-RTD oscillator that utilized optical-triggering to realize record output power performance (i.e., > 3 milliwatts) over a significant portion of the THz band (i.e., 300-600 GHz). Optimization studies have also been used to show the great promise of alternative types of staggered-bandgap hetero-systems [5, 6] that allow for the design of Hybrid I-RTD oscillators which utilize state-of-the-art laser technology (i.e., 1.55 micrometers) to realize predicted output power performance at room temperature that exceeds all other known types of all solid-state oscillators. This research work has provided a detailed design criterion for the entire hybrid circuit design, along with a practical implementation strategy for integrating the optical triggering and an analysis of the heating induced during large signal operation [7] and motivates the development of a new collaborative effort between small business and fundamental research that can be used to realize a practical demonstration of this important new technological capability.
PHASE I: The Phase I effort should apply new physics-based models towards the specification and conceptual design of a novel I-RTD hybrid oscillator that employs optical-triggering to achieve superior output power performance at THz frequencies. The design and optimization studies should also consider alternative types of staggered-bandgap hetero-systems and determine their potential for performance enhancements. The Phase I studies should also specify experimental methods for indirect testing/measurement of device dynamics and acquire data for critical device and circuit parameters where possible.
PHASE II: The Phase II effort should build and demonstrate a prototype I-RTD hybrid THz oscillator that exhibits state-of-the-art output power performance (e.g., > 3-10 milliwatts) across a significant portion of the THz frequency band. The Phase II effort is expected to include strong contributions from staggered-bandgap hetero-systems materials growth/fabrication, device/circuit design and optimization and oscillator measurment and characterization. The Phase II effort should also document the utility of the new oscillator in one or more military relevant THz applications.
PHASE III: The initial goals of the program are to demonstrate the performance and value of the new THz source in highly military relevant applications - i.e., such as monitoring of chemical and biological agents and standoff imaging of concealed threats. However, this same technology would have relevance to a number of private sector areas – i.e., such as advanced laboratory components for scientific characterization studies and for materials/process monitoring in commerical manufactering. Hence, a Phase III effort is expected that would explore these type or near-term private sector opportunities, and possible the exploration of longer-term opportunities such as short-range /wide-bandgap communications and ultra-fast data processing.

A07-T006 TITLE: Nanostructures for dislocation blocking in infrared detectors
TECHNOLOGY AREAS: Electronics
OBJECTIVE: Develop innovative nanostructures to block Si substrate associated dislocations from propagating into the active volumes of infrared photon detectors.
DESCRIPTION: Present day semiconductor technology requires that infrared focal plane arrays (IRFPAs) employ read out integrated circuits (ROICs) based on silicon (Si). As such, the growth of HgCdTe or III-V quantum structures on Si substrates offers significant advantages of lattice and thermal matching between the ROIC and the substrate. Si substrates are also of low cost and provide the potential for larger array formats. The main difficulties encountered in the growth of these detectors on Si are the large lattice and thermal mismatch between the materials (~19% for HgCdTe/Si) that gives rise to a high density of defects in the epilayers. Both difficulties have been partially overcome using buffer layers, as evidenced by the significant increase in crystal quality in the last 15 years. However, the defect density in the subsequently grown long wavelength infrared (LWIR) layers still is higher than that of epilayers grown on other substrates which are more expensive and often fragile as in CdZnTe substrates. The strain-induced defects propagate into the epilayers, which significantly reduce the sensitivity of LWIR infrared sensing devices and also create pixel to pixel nonuniformity. As research and development efforts advance, it has become obvious that defects are impeding the progress of IRFPAs with Si substrates.
This solicitation seeks to make use of nanotechnology to lower substrate related dislocation densities and increase uniformity for IRFPAs of interest to the Army. It has been recently noted that strain fields induced by quantum dot buffer layers may be employed to suppress the propagation of dislocations(1,2). It has also been suggested that several layers of quantum dots may be most effective in bending or merging dislocations(3). On the other hand, it is important that the quantum dot buffer layers should not themselves create additional defects(4). Thus, dot composition, dot size, and energy coherence are important parameters to control the strain and suppress the dislocation growth. Uniform quantum dot buffer layers may also improve the spatial uniformity of the remaining dislocations and the subsequent detector array. Other novel nanostructures may also provide the desired dislocation filtering properties(5,6).
PHASE I: Demonstrate a reduction in dislocation density by use of nanostructure buffer layers between Si-based substrates and LWIR infrared detector material. Estimate the yield of low defect layers, the improvement of array photoresponse uniformity compared to other techniques, and assess cost effectiveness.
PHASE II: Optimize the physical conditions necessary for effective suppression of dislocation growth. Fabricate and demonstrate LWIR infrared detectors grown on substrates with nanostructured buffer layers that effectively suppress dislocation propagation.
PHASE III: A large number of commercial applications will benefit from low cost infrared photon detectors to include night surveillance, product control, and system thermal management. This technique should also be useful to interface lasers, light emitting diodes, and Microwave/Millimeter Wave Monolithic Integrated Circuits (MIMIC)to silicon electronics. For this STTR, a Phase III effort should be devoted to developing a manufacturing process for infrared detector arrays with improved uniformity and sensitivity.

A07-T007 TITLE: Efficient and Robust Algorithms for Real-time Video Tracking of Multiple Moving Targets
TECHNOLOGY AREAS: Sensors
OBJECTIVE: To develop novel computational algorithms for real-time tracking of multiple moving targets. The algorithms need to maintain robust performance in complex urban environments and for tracking nonlinear motions.
DESCRIPTION: Video tracking technologies find applications in surveillance systems, autonomous vehicles, sensor networks, and precision munitions. For example, video surveillance plays a key role in force protection. Video tracking is a desirable targeting approach to terminal homing for smart weapons because of anti-jamming capabilities compared to GPS-based solutions. Key components of video tracking include target detection, track association, and target motion estimation. The major drawback of the approach of traditional Extended Kalman Filtering (EKF) is its performance degradation for tracking nonlinear motions and for handling non-Gaussian noises under high clutter. Improvements to EKF and various alternative approaches such as particle filtering or multiple-hypothesis tracking algorithms have been proposed to improve the performance and robustness of tracking algorithms, but often at the cost of intensive computation [1-7]. Current video tracking systems may work well in laboratory environments or under benign operational conditions, but perform inadequately under severe conditions with low signal-to-noise-ratio [5-7]. Target detection and track association remain challenging issues under such conditions.
The U.S. Army seeks development of novel video tracking algorithms with improved performance for military applications. The intended application is monitoring surroundings for stationary facilities or patrolling military vehicles such as High Mobility Multipurpose Wheeled Vehicle (HMMWV). Available inputs are visual and/or infrared video streams. Recent advances have lead to algorithms with significant reduction in computation requirements and to new approaches integrating detection with motion estimation [1-5, 8-9], which points to potential improvements of tracking performance. The algorithms developed under this STTR topic must be innovative and need to meet the following requirements. (1) They are computationally efficient and can be implemented for real-time tracking of multiple moving targets. (2) They maintain robust performance in the presence of high clutter, occlusion, dynamic range, illumination variation, orientation changes, and moderate image distortion. (3) They track several types of targets in urban environments including human, civilian vehicles, and military targets that could exhibit highly nonlinear motions. For example, a person of interest may walk, run, or stop. (4) They should be able to track a number of targets of different types simultaneously. No assumption of constant number of targets should be made. It’s anticipated that temporal information should be utilized in order to achieve robustness to mitigate temporary loss of frames or bad frames. The algorithms should deliver satisfactory performance for publicly available representative civilian and military data.
PHASE I: Effort in Phase I may be directed to the development of basic tracking algorithms, analysis of details of issues involved, and development of tools such as quantitative analysis or simulation software for the characterization and testing of the algorithms under simplified scenarios. Quantitative characterization of tracking performance should be obtained. Advantages and disadvantages of the proposed algorithms should be explicitly identified and documented.
PHASE II: Efforts are suggested to focus on improving efficiency and robustness of tracking algorithms. Simulation tools should be expanded to consider practical operation conditions with realistic modeling of urban clutter and nonlinear target motion. Tracking performance should be documented and characterized based on experimental data including publicly available representative civilian and military data.
PHASE III: Phase III will further develop and refine algorithms for commercial and military applications. Dual-use applications include navigation of autonomous systems and security surveillance.

A07-T008 TITLE: Algorithms for Image Content Indexing and Information Retrieval from Unstructured or Semi-structured Complex Database
TECHNOLOGY AREAS: Information Systems
OBJECTIVE: To develop innovative computational algorithms for effective image content indexing and information retrieval that retrieve relevant information from unstructured or semi-structured complex database. The retrieved information should be associated with statistical measures of its relevance.
DESCRIPTION: Human can recognize objects with ease even in complex scenes because of the availability of a massive knowledge base and the ability to efficiently retrieve information from it. Therefore, an alternative approach to automatic target recognition is to create a comprehensive database that contains objects under as many variations of environments and operation conditions as possible, to continuously update the database as new images collected, and efficiently compare observations with objects in the database, all by utilizing increasing computing capabilities. As a first step toward this goal, this STTR topic is aimed at developing effective algorithms for analyzing and indexing image contents from unstructured or semi-structured (e.g., keyword indexed) database with minimum human intervention to reduce false classifications. One potential approach is segmenting objects in an image and indexing the objects based on the contextual information of the image such as scene. Image indexing can be further restricted to defense relevant objects such as military vehicles. Algorithms for information retrieval should allow flexible input formats such as sketches and sample images and must return search results within fraction of a second after searching through a potentially large database created by the outputs of image content analysis and indexing process. Successful retrieval requires intelligent elimination (e.g., through cognitive reasoning) of false positives. The retrieved information should be associated with statistical measures of its relevance.
While text search engines have met with commercial success, the development for image search engines is still in its infancy. Commercial image search engines are limited to keyword search. The main challenges for image indexing and retrieval include (1) lack of low level signatures that can uniquely describe an object of interest, (2) the difficulty of converting low level signatures into high level searchable features, and (3) the wide range of potential variations of such characterizations under different operation environments and conditions when data were collected [1-6]. Over the last decade, a number of testbeds for content-based image retrieval have been established with various aspects of emphasis based on rudimentary features such as color, texture and shape [5-7]. Advances in a few relevant fields (e.g., music information retrieval [4]) also provide knowledge and experience that can be used to aid image retrieval. Recent research suggests that performance can be improved by semantic retrieval [5, 7].
The purpose of this project is to leverage recent progress to advance technologies for military relevant image indexing and information retrieval. The intended application to automatic creation of knowledge base for automatic target recognition systems and decision-making is of critical importance to the Army’s Future Combat Systems.
PHASE I: Phase I may be directed to the analysis and design of algorithms for image content extraction and indexing, and query-based information retrieval. A small-scale computer test should be established. Feasibility study should be performed with documented results to prove that the proposed approach has the potential of success.
PHASE II: Efforts in Phase II are suggested to focus on expanding the scale and scope of the algorithms. Innovative approaches are needed to maintain robust performance for handling large complex unstructured or semi-structured database. Representative examples of publicly available civilian and military data should be processed and added to the database. Potential tasks include (i) demonstration of the capability to analyze content of generic images with minimum human intervention to reduce false classifications, (ii) design of approaches to efficient image-content indexing, and (iii) demonstration of quality of performance for information retrieval with sketch or image query input. A proof of concept prototype system is anticipated.
PHASE III: Phase III military applications include automated creation of target knowledge database for automatic target recognition. Creation of new image indexing systems and launching of the next generation image search engines will have enormous technological impact on both civilian and military sectors with unlimited commercialization potential.

A07-T009 TITLE: Frequency-agile monolithic Ka-band filter
TECHNOLOGY AREAS: Electronics
OBJECTIVE: The goal of this research and development is an efficient, light weight and small footprint radio frequency filter that is widely tunable within the Ka band.
DESCRIPTION: Though technology utilizing the Ka band (~26 – 40 GHz) is readily available, applications are constrained by insufficient temperature stability, reliability, size and efficiency. Recent research in the growth of bulk, thin film and nanocomposite active materials has resulted in material systems that respond naturally and efficiently within the Ka band. Some ferroelectric and ferromagnetic materials, for example, are active in the Ka band and can be continuously tuned through applied electric or magnetic fields. Recent breakthroughs have demonstrated that ferroic materials and device structures can be harnessed for frequency-agile monolithic radio-frequency (RF) devices in the Ka band without the need for prohibitively large external fields.
