Body Cooling Garment
NATICK SOLDIER SYSTEMS CENTER
The technology comprises both the cooling garments and the method for adhering tubing to the fabric substrate. The preferred method employs adhesive dots to fasten the tubing to the fabric, forming a single component. This component is fused to a second layer of fabric, creating a tricomponent construction, with the tubing “sandwiched” in the center of two breathable layers. This method eliminates the need for stitching to hold the tubing in place. Sewn tubing has the problem of potential pinhole puncturing of the tubing, skin irritation from the threads themselves, lengthy manufacturing time, and needleholes that allow unwanted chemicals to penetrate the fabric. This technology is also superior to brushed or rolled on adhesives which destroys porosity. Variations can be made for a chemical suit. Foot cooling is covered in a patent application. Five US patents have issued and a sixth patent application has been filed. The US Army Natick Soldier Center (NSC) seeks to commercialize through patent licensing a body cooling garment which utilizes fluid-carrying tubes and provides both air and vapor permeability to make a flexible, comfortable garment. This garment is breathable and launderable, and will maintain comfortable core body temperature in hot conditions, whether indoors or outside. The vest can be connected to a faucet or cooling unit and unhooked briefly for mobility, or be more permanently tethered.
Convertible Patient Isolation Pod
ARMY MEDICAL RESEARCH AND MATERIEL COMMAND
The Convertible Patient Isolation Pod protects individual patients in a flexible, transparent, air-impermeable enclosure suited for transporting a patient out of a contaminated environment. It allows the caregivers safe access to stabilize critical patients without having to ‘decon’ them. Glove-box access features are designed to enable medical interventions. If needed, the outside of the unit can be decontaminated much faster than the patient. An acceptable breathable air environment within the pod is achieved with an air intake at the head end of the pod and an air exhaust and filter at the foot end. A portable air blower with an air filter circulates air in and out of the pod to maintain the acceptable environment. The unidirectional air flow within the pod limits further contamination. The pod can include tear-resistant gloves and handles to facilitate patient manipulation without the need for ancillary equipment. The easily deployed Convertible Patient Isolation Pod is most attractive for use in rescue and lifesaving operations involving a wide range of transport such as aircraft, land vehicles, hospital gurneys, etc USAMRC seeks firms interested in applying the technology for their particular needs. Licenses for commercial production and sale are available. This technology was patented by AMRMC under US Patent #6,418,932. Additional information is available upon request.

The Journal Bearing Analysis Suite
ARMY RESEARCH LABORATORY
Background The Journal Bearing Analysis Suite is the first transient journal bearing code to implement the Jacobsson-Floberg-Olsson (JFO) boundary conditions. It uses a mass conserving algorithm devised by Professor Emeritus Harold Elrod, Columbia University, and was written by David E. Brewe of the U.S. Army at the NASA Lewis Research Center in 1983. Since then, new features and improvements have been built into the code by several contributors supported through Army and NASA funding via co-operative agreements with the University of Toledo (Prof. Ted Keith, Jr. and Dr. D. Vijayaraghavan), National Research Council Programs (Dr. D. Vijayaraghavan). All this was conducted with the close consultation of Prof. H.G. Elrod and project management of D. E. Brewe. This version is written to perform a thermo-hydrodynamic analysis of fluid film Journal bearings using collocation across the film thickness at Lobatto points and using Legendre polynomials. The Technology Planetary gear systems are an efficient means of achieving high reduction ratios with minimum space and weight. They are used in helicopter, aerospace, automobile, and many industrial applications. High-speed planetary gear systems will have significant dynamic loading and high heat generation. Hence, they need jet lubrication and associated cooling systems. For units operating in critical applications that necessitate high reliability and long life, that have very large torque loading, and that have downtime costs that are significantly greater than the initial cost, hydrodynamic journal bearings are a must. Computational and analytical tools are needed for sufficiently accurate modeling to facilitate optimal design of these systems. Sufficient physics is needed in the model to facilitate parametric studies of design conditions that enable optimal designs.
Portable Biological Agent Detection The “PCR Rotary Thermalcycler Unit”

An established method for rapidly identifying a genetic fingerprint (the DNA) of biological materials in even trace samples is Polymerase Chain Reaction, or PCR. Yet, application of PCR in the field has been challenged by the cost and difficulty of currently transportable PCR equipment. The PCR Rotary Thermalcycler Unit is designed to be a simple-to-use, lightweight, portable device for rapidly detecting and identifying the presence of specific biological species while in the field. Its unique heating concept and design configuration is intended to enable convenient and affordable PCR for a wide range of field applications such as: Detecting diseases and agricultural pests Identifying dangerous biological agents Testing food and water for contamination Tracking geographically a species or biological agent Design Benefits: Portable and easy to operate On-the-scene analysis in 5-20 minutes Expandable for higher sample counts Self-contained platform (integral batteries and detectors) with intuitive display The U.S. Army Center for Health Promotion and Preventive Medicine seeks licensees to commercialize a PCR Rotary Thermalcycler, reducing the design to practice. Further development is possible under a Cooperative Research and Development Agreement (CRADA) for prototype development, testing, & adaptation of commercially available reagents. Additional information is available through FirstLink.
Teledentistry Consult Management System
TechLink
The US Army seeks to commercialize through patent licensing a web-based system for electronically storing and disseminating dental records and images between generalists and specialists for the purpose of rendering a diagnosis or determining a treatment plan. The invention reduces the need for patients to travel to specialists, increases the quality of care, and provides a means of electronically documenting dental consultations. The Technology: The Walter Reed Army Institute for Research has developed a web-based communication technology that carries information and provides a series of user interfaces or templates for collecting and disseminating data relating to a patient or a patient’s condition. The system includes a storage capability that enables the data to be accessed or amended at any time. The system is used for the creation and transfer of dental consult records (including images), diagnosis and treatment records, and communication between referring provider and specialist. A series of prompts and drop-down menus ensures that the appropriate data is input by the referring and consulting dentists. An image manipulation routine allows the consulting dentist to zoom in and out, invert, rotate, flip and change the contrast and brightness of images. The technology has been reduced to practice by the Army. Background and Opportunity: The US Army has a need to provide acute dental care to soldiers in the field while minimizing the use of medical evacuation. The teledentistry consult system allows for expert consultation to theater-based dentists and soldiers, which increases their access to quality care and reduces the cost associated with medical evacuation. A patent filed by the Army (published patent No. 20030078806) and the software code are available for commercial license. Benefits: • Increases patient access to specialists • Reduces cost of dental health care • Creates electronic records of consultations Contacts: • Kurt Rued, [phone removed], [email removed] • Dan Swanson, [phone removed], [email removed]

Avenger Bustle Box Delamination Reduction
National Center for Defense Manufacturing & Machining
Problem / Objective Letterkenny Army Depot (LEAD), Chambersburg, PA is currently in the process of producing components for the Avenger Bustle Box using a new composite material. This composite material is highly desired due to its superior performance and 45 percent weight reduction in comparison to the current bustle box material. LEAD is currently manufacturing these new composite panels with the use of a waterjet cutting process. The current waterjet cutting process has been identified as the cause of slight delamination of the outer layers of the composite material. This process also causes water damage between the layers by impregnating the composite core with water.The current waterjet cutting process time runs at about 70 inches per minute. Accomplishments / Payoff Process Improvement The NCDMM initiated the development of a solution by having test material, supplied by LEAD, sent to the NCDMM Testing and Development Lab. The NCDMM with the assistance of an Alliance Partner developed several cutting tools for testing. The first phase of testing began by researching various cutting tool geometries. Once the tool geometries were selected, optimal cutting speeds and feeds were determined. Photos of the cutting tools were taken, tool wear was measured, and the data was recorded. All tests were conducted at full depth/full slot. The initial test data results showed that some tools preformed better than others. Therefore, the main focus was redirected to the cutting tool that provided the least amount of delamination to the outer layers of the composite material. After careful evaluation, one tool was selected for additional life testing. In order to enhance the productivity of the selected tool, the NCDMM developed and conducted a Design of Experiments (DOE) to find the optimum run parameters. Upon completion of the DOE, the new tool design was capable of running at 119 inches per minute. The NCDMM then proceeded to investigate the cutting tool life. Follow-up life test results ran at 119 inches per minute and showed significant improvements to the composite quality as well as a reduction in cutting time. This was achieved with minimal wear to the cutting tool. The NCDMM, with the assistance of a key Alliance Partner, was able to develop an advanced cutting tool that would efficiently machine the composite material to the specifications required by LEAD. Implementation and Technology Transfer The following tool recommendations and process was made to LEAD: Proper cutting tool Proper cutting parameters and conditions Expected Benefits from the new Tool Geometry Increased productivity (119 inches / minute from 70 in. / min.) Better part quality (no delamination, or water impregnation) Better utilization of machining equipment
Night Vision Goggle Manufacturing Support
National Center for Defense Manufacturing & Machining
Problem / Objective Letterkenny Army Depot (LEAD), located in Chambersburg PA, received an order to manufacture 12,000 night vision goggle (NVG) plates. These plates are used to mount the NVG to the Soldier’s helmet. However, the quantities needed had increased over four fold from 12,000 to 52,000 (7,000 NVG plates per month) near the time of production. Based on these quantities, delivery dates, and current workload, LEAD requested the assistance of the National Center for Defense Manufacturing and Machining (NCDMM) to help optimize the NVG plate manufacturing process. The NCDMM and LEAD determined that based on the expected run time of forty-six (46) minutes for every ten (10) parts, the required monthly volume would be unattainable under current operating methods. NCDMM and LEAD personnel determined that optimization of the current NVG tool path and tooling was necessary to improve the capability of the depot to meet the delivery schedule. NCDMM engineers traveled to LEAD to assess the current machining operation used to produce the NVG plates. LEAD machining personnel were interviewed and the total machining process was evaluated. It was determined that the NCDMM would deliver and implement optimized tooling and tool paths as well as a Mastercam (CNC programming software for machine tools) part file allowing LEAD the ability to easily continue with future improvements. Accomplishments / Payoff Process Improvement NCDMM engineers developed a Mastercam file complete with all fixturing and part models. Tool paths were developed and optimized through verification software. Key areas were then tested at the NCDMM Testing and Development Lab on NCDMM’s Haas VF-6 machining center to prove out the tool path. Optimized tooling was selected and implemented with the new tool path. Tool holders were also selected and balanced to perform at the optimum speeds. Implementation and Technology Transfer Once tooling was selected and the tool path optimization was completed, NCDMM engineers implemented the optimized process at the LEAD facility on their Haas VF-5 machining center. Expected Benefits The optimized tooling and tool path resulted in a 30% reduction in cycle time compared to the original program. Implementing this solution enables LEAD to meet its increased production schedule of 52,000 plates. This improvement also reduces the estimated cost $2.18 per NVG plate. This represents a savings of $113,360 over the initial order of approximately 52,000 plates.

Rapid Clotting Technology
TechLink
The US Army seeks a commercial and/or cooperative development partner for a rapid clotting technology for use in a variety of emergency and surgical situations. The Technology: The US Army has patented the combination of recombinant factor VIIa and fibrinogen for stemming blood loss and restoring hemostasis. This combination is administered intravenously and circulates safely through the body to the site of injury. The approach would be especially useful for treating multiple wounds and internal bleeding. Background: Hemorrhage is one of the most common causes of death among those who die prior to reaching an emergency room or expire in the operating room. Research has demonstrated the individual effectiveness of recombinant factor VIIa and fibrinogen in clotting. Factor VIIa plays a key role in activating the blood coagulation process and fibrinogen provides the raw materials needed to make an effective clot. The combination of factor VIIa and fibrinogen is a logical approach to treating emergency and surgical bleeding. Benefits: Portable: Can be used to treat trauma in the field or en route to a hospital Shelf Stable: Components can be stored for years in dry form or months wet Easy to Use: Reconstitutes quickly and is administered via IV Useful in Difficult Cases: Able to help control bleeding in hard-to-reach injuries, such as pelvic venous plexus tears and deep liver injuries Opportunities: Patent No. 6,825,323 is available for licensing. Further joint development with the Army Institute of Surgical Research is possible under a Cooperative Research and Development Agreement (CRADA). Additional details of the technology, an overview of the licensing process, and an interview with the inventor, are available through TechLink.
Immunoliposome Polymerase Chain Reaction (ILPCR) Assay
TechLink
A simple-to-make diagnostic immunoassay capable of sub-femtomolar sensitivity that is very robust against matrix contaminations. Background and Technology: The US Army has developed an ultrasensitive immunoassay capable of sub-femtomolar (10-15) limit of detection. ILPCR technology overcomes the limitations of traditional immuno-PCR by encapsulating the signal amplification DNA/reporter inside a liposome, and incorporating a receptor (e.g. biotin or gangliosides) as the detection reagent into the bilayer of the liposome. After immobilization of the target analyte by the specific capture molecule and co-binding of the detection reagent, the liposomes are ruptured to release the reporters, which are quantified by real-time PCR. Preparation of the ILPCR reagent is simple. Unlike traditional immuno-PCR, synthesis of an antibody/DNA conjugate is not needed. By encapsulating the reporter inside the liposome, the reporter is protected by the liposome from degradation by impurities, which substantially reduces the possibility of false-negative results, and enables the use of DNase I to all but eliminate DNA contamination and false-positives. ILPCR’s improved sensitivity is due in part to the high number of reporters per binding event and the low nonspecific binding of the reagents. The assay has shown 5 orders of magnitude in dynamic range. Benefits:Ultrasensitive: Demonstrated sub-attomolar (10-18) and sub-femtomolar (10-15) detection threshold capabilities under ideal and “real-world” conditions respectivelyBroad Dynamic Range: Five Orders of Magnitude Accurate: Protection of the reporter inside the liposome greatly reduces false-negatives; eliminates DNA contamination, hence substantially reduces false-positives Versatile: Reduced to practice in biotoxins (botulinum and cholera), oncology biomakers (CEA), and viral HIV detection systems; applicable to a multitude of other analytes of commercial interest Simple: Reagents are easy to manufacture, inexpensive, and have a long shelf-life Status and Opportunity: Available for license and commercialization:One issued US patent (7,582,430), one published US patent (2009/0176250), and various pending foreign filings (WO2005/067583) Peer-reviewed journal articles available; additional information under non-disclosure agreement Potential for R&D; collaboration with inventors Dr. Tim O'Leary & Dr. Jeff Mason
Variable Height Bulkhead
TechLink
Field personnel with the US Army Corps of Engineers – New York District (USACE), have developed a self-adjusting, variable height bulkhead for use along beaches and waterways where it is desirable to preserve the view, but control is needed against wave action and storm surges. The USACE is interested in cooperative research and development efforts for this technology, and in licensing out its pending patent (Pat. Appl. 12/006,757, “Hydrostatically Operated Variable Height Bulkhead”, filed Jan 02, 2008). Waterfront properties and roadways are often protected by permanent bulkheads. It is a challenge to build them tall enough to be effective, but low enough to preserve high-value views. Some of these bulkheads are equipped with pumps to deal with storm surge and wave-induced overtopping. This is a costly and maintenance-intensive solution that is particularly ineffective for long stretches of bulkheads as may be needed for roadways and marinas. The USACE team has devised a “floating” solution that adjusts vertically, using only the mechanism of a rising water level. It does not require operator attention, pumping or other mechanical controls. It can be retrofitted to any existing bulkheads that are permanently located, and that have some depth of water next to them. A floating internal wall is constructed in between the existing barrier and a second, barrier wall. When a surge occurs, the floating wall rises on the water. As the water recedes, the floating wall drops back between the two external walls, and a cover cap falls back in place on the top ledge. Design attention has been given to preventing the inner wall from hanging up on debris, and from rising too far. Examples of desirable applications include marinas, private waterfront property, harbors, highways, industrial overflow basins, and municipal properties.
Transparent, Reinforced, Composite Fibers for Lenses and Windows
TechLink
The Natick Soldier RD&E; Center is developing transparent, multi-component, reinforced composite fibers to provide improved transparent ballistic protection for Warfighters. These new reinforced fibers range in complexity from simple sheath-core structures to arrays organized as “islands in the sea” and can be used to create transparent fiber reinforced composites articles such as lenses and windows. At present, Natick scientists have been able to demonstrate retention of strength of fibers during consolidation,and levels of visible light transmission over 80%. Natick’s best transparent reinforced composite structures have low density and currently offer 10% to 20% greater ballistic impact resistance as compared to molded polycarbonate, the standard for plastic optics and glazing. Moreover, these transparent, reinforced composites are made from polypropylene, a base material that costs about one-third of typical polycarbonate. The current composites may already be competitive for skylights or applications where diffuse light transmission is acceptable. However, these structures are more complex to manufacture than a simple injection molded lens, and while they achieve good light transmission, they have not yet achieved the optical clarity required for eyewear. Scientists at Natick believe there is significant room for improvement in the technology, particularly for applications that require greater optical clarity such as goggle lenses and face shields. Benefits 10-20% greater ballistic protection (with potential for improvement) Lighweight, low density Low-cost starting materials Opportunities for joint inventions and licensing The US Army is seeking improved transparent ballistic protection at an affordable cost for Warfighters, vehicles and structures. Scientists at Natick have developed and have a pending patent on a technology that relates to transparent, reinforced composites for lenses, windows, etc. Opportunities to collaborate with Natick under a CRADA, to jointly improve the technology, and to license the pending patent are available.
Chlorine Dioxide Disinfectant and Handheld Sprayer
TechLink
The US Army has primary responsibility for food safety for the US military. As such, it seeks to protect the Warfighter from bio-warfare agents, agri-terrorist threats, and the spread of foodborne illness through secondary contamination of food contact surfaces. The latter is achieved mainly through preventive techniques designed to improve the sanitation of food preparation surfaces and food-processing equipment. D-FENS conveniently generates aqueous solutions of the proven disinfectant chlorine dioxide. Chlorine dioxide routinely inactivates food pathogens and resistant bacterial spores, while minimizing hazards to the user and the environment. Foods treated directly with chlorine dioxide are rendered safe without a loss of quality. D-FENS can also disinfect sanitary surfaces, clean rooms, and medical equipment. Add water on day of use. Benefits: Controlled, point-of-use generation of ClO2 without transporting the weight of water Surface disinfectant treatment by spraying, pouring, or immersion No unpleasant odor Multi-use spray dispenser Safe for human use and the environment The US Army is seeking a licensee for this patent-pending technology which has been reduced to practice. Some further development of a mixer/sprayer apparatus would be required. Collaborative research and development (CRADA) opportunities may be possible.
Porcelain-Enamel Coated Structural Steel
TechLink
The corrosion of embedded structural steel is the major cause for failure of reinforced concrete. As steel corrodes, the rust coating grows in thickness and puts the concrete in tension, cracking it around the steel and destroying any bonding of the steel to the concrete. The US Army Engineer Research and Development Center is pioneering a system for firing a specially-prepared vitreous enamel coating that contains hydraulically-reactive calcium silicates onto reinforcing steel. This coating provides durable protection from corrosion even in aggressive chemical environments. It also changes the fundamental chemistry at the concrete-to-steel interface by destroying the weak interface layer that normally forms at the steel surface. Researchers at the ERDC have developed a patent pending cement-vitreous enamel coating for steel that is used to reinforce concrete (i.e., rebar, steel fibers, and metal plating). This porcelain coating more than triples the bond strength between concrete and steel, and prevents damaging steel corrosion. The ERDC is interested in licensing the patent application (No. 11,234,184 “System and Method for Increasing the Bond Strength Between a Structural Material and Its Reinforcement”) and in cooperative research and development efforts.
Hybrid Phased Communication Array
ARMY AVIATION & MISSILE RESEARCH, DEVELOPMENT & ENGINEERING CENTER
This technology was the Army winner in the OSD Office of Technology Transition & DoD TechMatch Hot Technologies Contest. The present invention is a communication module provided with a Transmit/Receive (T/R) element fabricated from psuedomorphic HEMT, High Electron Mobility Transistor technology (PHEMT). The T/R element drives multiple Radio Frequency MEMS switch-based phasing elements. Each of the phasing elements connects to a corresponding radiation element. A large quantity of the communication elements can be placed on a single substrate chip so as to provide for a reliable and cost effective device. The device will continue to transmit and receive even if some elements fail. The invention has a wide-range of military and commercial communication applications from guided missile technology to cell phone communication. Benefits Redundancy; allows continued function of the system as a whole with one or more failed subsystems Lower cost Reliable and consistent transmission and reception of radio waves A communication device having a Transmit/Receive element fabricated from High Electron Mobility Transistor technology, which advantageously drives multiple radiating elements This technology allows for reliable and continuous transmission and reception of radio waves (for example, microwaves). The invention includes a communication array which is comprised of a plurality of communication modules formed on the same substrate. Each communication module has a transmit/receive module which drives a plurality of radiating elements. Each transmit/receive module is provided with transmitting and receiving components and a switch for alternately transferring from a receiving function to a transmitting function. The technology allows several radiating elements to be driven by a single transmit and receive module. Since numerous communication modules are present on a given substrate, reception and transmission will continue even if some of the modules fail. Each communication module is fabricated from pseudomorphic high electron mobility transfer (PHEMT) technology. The transmit/receive switch is a microelectromechanical system (MEMS). The invention can be fabricated at low cost. The small size of the invention allows it to be placed on and at a desired location with reduced size constraints.
Medical Tube Securing Device
ARMY MEDICAL RESEARCH AND MATERIEL COMMAND
This technology was the Army winner in the OSD Office of Technology Transition & DoD TechMatch Hot Technologies Contest. Often burn patients have problems breathing on their own due to scorched esophagi, and damaged airways caused by smoke inhalation. Therefore it is necessary to intubate the patient so that they can breathe. This technology will prevent cuts and tears in the patient's mouth caused by endotracheal tubes. These tubes must be secured in order to prevent inadvertent removal. Currently, these tubes are secured in one of two ways, depending on the nature and location of the burns: A semi rigid bite block is fastened to the breathing tube with cotton twill tape, and then the tape is secured around the patients head. This method produces a very secure attachment, but often results in damage to the soft tissue at the corners of the patient’s mouth. In addition, there have been cases of patients losing their incisors (as this is where this bite block rests) due to continuous clamping of the jaw on the bite block. Commercially available tube holders are utilized, when practical. These devices are not utilized in patients with facial burns, as they do not secure well as a result of the creams and ointments needed to treat the burn. These do produce a relatively secure attachment when used; however, there have been issues with the size of these holders preventing adequate oral care, as well as producing pressure sores on the lips of the patient. This device prevents damage to the incisors, and helps to prevent pressure sores on patients’ lips. The last thing a burn patient, let alone a polytrauma (both burns and amputations) patient needs to deal with are sores on their lips or loss of their teeth due to intubation. The market is potentially huge, as this can be used on any patient requiring intubation. There are thousands of intubations per year globally.
The Photonic Crystal-Based Optical Waveguide Modulator
ARMY AVIATION & MISSILE RESEARCH, DEVELOPMENT & ENGINEERING CENTER
The technology developed is a photonic crystal-based optical waveguide modulator. This invention pertains to the field of photonic ban gap technology that permits the virtually lossless unidirectional propagation and phase shift of light. A waveguide has upper and lower cladding regions. A core of the waveguide made of a non-linear optical polymer is positioned between the upper and lower cladding regions. A first electrode is connected to the upper cladding region and a second electrode is connected to the lower cladding region. The upper cladding region and the lower cladding region are made of photonic band gap materials and have multiple periods of cladding layers with each period having a first layer having a linear refractive index of n.sub.1 and each period having a second layer having a linear refractive index of n.sub.2. The waveguide allows for minimal distances to exist between the electrodes while allowing for virtual lossless cm-long transmission of propagating light. By applying a voltage to the electrodes, the propagated light can be modulated. Benefits Enhanced mill grinding Expanded imaging options through interchangeable optical devices Centralized or local image enhancement center Core is made of non-linear optical polymer Marketability This Technology has a variety of potential applications including video imaging, surveillance equipment, and medical devices/screens for the defense, security, medical and industrial sectors
Disinfectant-sprayer for Foods and Enhanced Sanitation (D-FENS)
NATICK SOLDIER SYSTEMS CENTER
The US Army has primary responsibility for food safety in the US military. As such it seeks to protect the Warfighter from contaminants and the spread of food borne illness. This is achieved mainly through preventive techniques aimed at improving the sanitation of food, food-processing equipment, and food preparation surfaces. A new process for producing aqueous chlorine dioxide for surface disinfection and decontamination has been developed by scientists at the Natick Soldier-R, D&E; Center to combat against contaminated against surfaces, equipment and fresh food. D-FENS (Disinfectant-sprayer for Foods and ENhanced Sanitation) uses novel chemistry for the generation of chlorine dioxide with a collapsible spray bottle; making ClO2 available for use in convenient, small, batch sized delivery systems. When combined with a collapsible spray bottle this technology eliminates the logistics issues associated with chlorine dioxide by providing a small, light weight "just add water" system. ClO2 is a powerful but user and food friendly compound for sanitizing and disinfecting solid surfaces. Unlike many other common sanitizers/disinfectants ClO2 will kill mold, fungus, and spores along with bacteria while still being safe enough to use with and around food products. However chlorine dioxide normally requires continuous onsite process generation by means of capital intensive ClO2 generating equipment. This conventional process used for generating CIO2 is costly and cumbersome and completely unnecessary with D-FENS. Benefits Disinfectant-sprayer for Foods and ENvironmentally-safe Sanitation (“D-FENS”) is a “green technology” with performance and logistics advantages over COTS items. Eliminates need to use/transport acids, and lightweight packaging eases logistics and reduces weight, cube, fossil fuel use and carbon footprint. Generates ClO2 on-site from safe dry powders mixed with water. ClO2 is EPA-registered & FDA-approved. Controlled, point-of-use generation of ClO2 without transporting the weight of water. Surface disinfectant treatment by spraying, pouring, or immersion. No unpleasant odor. Unlike conventional methods for producing chlorine dioxide, the NSRDEC process does not require the use of acids rendering the reaction products (ClO2) noncorrosive.
Multifunctional Chest Tube Instrument
TechLink
The US Army has developed a patent-pending chest tube instrument that incorporates a needle driver tip, suture scissors, and clamp into one tool. Instead of handling four instruments, the new invention, in conjunction with a scalpel, is all that is needed to place a chest tube. Background and Opportunity Ergonomic studies of thoracostomy procedures and practitioner feedback demonstrate that a reduction in the number of instruments needed to complete a procedure is beneficial. One chest tube placement typically requires the use of four instruments. Each item required is another item that must be carried, wastes time due to swapping or mishandling, and increases the likelihood of accidental nicks and sticks. The Army’s invention cuts the number of instruments in half by combining the functionality of a clamp, needle driver, and scissors into one tool. Benefits Saves time - Time is not wasted by grabbing additional instruments Simple - Removal of two instruments, simplifies chest tube placement Safe - Fewer instrument transfers means fewer opportunities for accidental nicks and sticks, and eliminates the need to rest instruments on a platform or potentially unsterile surface.
Apparatus and Method for Multi-Channel Equalization
ARMY AVIATION & MISSILE RESEARCH, DEVELOPMENT & ENGINEERING CENTER
The present invention is a communication system with a multi-channel array antenna that utilizes a receiver matching process that adapts the pass band frequency response of each channel to a selected reference channel. This process is implemented digitally by inserting a tapped delay line filter in each channel, selecting one of the channels as a reference, and adapting the others to match the reference in both phase and amplitude. The process is performed for each system calibration cycle, which occurs just before receive data is captured and processed. The improvements include an apparatus and an algorithm that select a reference channel in the adaptive process during each system calibration cycle, producing optimal, or near optimal, channel matching. This technology may be applied to radar, sonar, seismic, imaging, satelite, GPS, communication devices and wireless communications. Benefits Equalizing a multi-channel electronic communication system Enhanced calibration signal Maximizes the number of channels selected by sampling as many of the available channels as is practical given the limitations of the system
Super-Resolution Image Reconstruction
TechLink
The SRIR Technology is a practical, robust, low computation overhead algorithm to obtain high resolution (HR) images from low resolution (LR), under-sampled digital imaging equipment. This US Army patented algorithm increases the resolution of the reconstructed output image using the existing imaging device from a sequence of low resolution, under sampled, imagery. By removing aliasing due to under-sampling, SRIR can also improve range performance of the sensor. Background and Technology Super-Resolution Image Reconstruction exploits the subpixel movement of an image sequence. When LR images have subpixel shifts between successive frames, they convey different information about the same scene.

Improved Tissue Sections for Light and Electron Microscopy
TechLink
The US Army Medical Research Institute of Chemical Defense (USAMRICD) seeks to commercialize through patent licensing an improved method for preparing the same frozen tissue sample for both light and electron microscopy. Background USAMRICD has developed and patented a procedure for preparing frozen skin samples that can be subject to various staining procedures, including immunohistochemistry. This invention is an improved method for creating a preserved, free-floating cryostat skin section for easy processing and analysis from light microscopy to electron microscopy. Conventional frozen skin sections tend to be thick and do not lend themselve to both light and electron microscopy. The Army's procedure for floating the skin sections and applying a cryoprotectant solution after cryopreservation, results in good immunostaining, good ultrastructural integrity of the basement membrane zone and good morphological clarity using the same sample under light and electron microscopy. Benefits Faster: Rapid results from immune-staining using light and electron microscopy Clearer: Avoids the clumping and thickness associated with traditional cryo and vibroatome sections Versatile: Potential applications for diagnosis of immune-related skin and renal disorders in addition to the demonstrated value in the diagnosis of skin basement proteins This invention is currently available for license and commercialization.
Digital Optical Method
ERDC CONSTRUCTION ENGINEERING RESEARCH LABORATORY
This technology was the Army winner in the OSD Office of Technology Transition & DoD TechMatch Hot Technologies Contest. The ERDC-CERL along with the University of Illinois have developed a new plume opacity measurement technology know as Digital Optical Method (DOM). This new algorithm was developed to apply light extinction theory and estimate opacity values. Along with the algorithm; two models(transmission and contrast were developed to more accurately measure opacity. DOM estimates the opacity of plumes in the out door ambient environment by analyzing digital images that are produced by off-the-shelf digital cameras. The American Society for Testing and Materials currently employs US Method 9, which relies on human visual perception to measure opacity. The DOM method provides improved consistency and accuracy of the measurements and permits retention of a digital record of the event. After many test and analysis it was concluded that 100% of DOM readings meet the criteria of Method 9. Benefits Reduction of labor costs Improved accuracy Reliability and objectivity Minimized litigation Enduring records in the form of digital photographs
Thermally Repairable Composite
TechLink
A Thermosetting matrix and glass fiber combination that can be heated after failure to restore properties of the composite system. Background and Technology: Composite materials that are subject to vibration and stress form small fractures and eventually fail irreversibly at the interface of the polymer matrix and reinforcing fiber. The U.S. Army and Drexel University have developed a soltion to this problem by incorporating reversible bonds into polymer networks. The technology combines a furan-fuctionalized glass fiber. When broken, the thermoreversible bonds between these materials can be healed on site at temperatures above 90 degrees Celsius. The technology represents a simple and effective method for creating a fiber-reinforced composite system with remendable interfaces. Benefits On-Site Repair: Potential for on-site healing of composites with a local heat source Effective: Laboratory testing of single fibers has realized healing capabilities up to 100% Repeated Healing: Demonstrated healing capabilities for at least 5 cycles Broadly Applicable: Tested in epoxy-amine systems but the chemistry should be applicable to any composite system with a hydroxyl or vinyl group Cost-Effective: Furan chemistry is based on inexpensive, renewable natural products Simple: Basic tank mixing and uncomplicated chemistry Status and Opportunity One U.S. patent application available for license Method reduced and tested in laboratory samples Peer-reviewed journal articles available with additional information under non-disclosure agreement Potential for R&D; collaboration with inventors
Nano-Engineered Additives for Active Coatings
ARMY RESEARCH LABORATORY - ABERDEEN
Researchers with the U.S. Army Research Laboratory (ARL) have developed and are patenting novel additives for coatings systems that spontaneously segregate to the surface of the coating. These macromolecular transports (MTs) can be coupled with traditional additives to control their distribution in a cured film, and the MTs are compatible with a wide range of military and commercial coating chemistries. This autonomous concentration at the surface of the film translates to reduced additive quantities required for desired surface properties (i.e., antimicrobial activity), as well as reduced impact on the bulk properties of the film. Potential applications include, but are not limited to, antifouling coatings for marine applications, pool coatings, coatings for hospitals and wood treatment. ARL has successfully produced a technology that will “float” anti-microbial compounds to the surface of a curing polymer matrix (Figure 2). Self-segregating materials address several issues: decreased additive requirements; minimize mass transport issues; minimize diffusion limitations; minimize impact on physical properties of base coating. Figure 4 shows the impact of MTs with antimicrobial characteristics when dispersed in a thermoplastic polyurethane matrix. The additives clearly reduced the appearance of plaques, and samples have demonstrated 99.9999 % killing efficiency with 1 wt % of additive without negative effects on the base coating. MTs have also been incorporated into various commercial off-the-shelf paints from local home improvement stores. The U.S. Army has developed an inexpensive additive that spontaneously segregates to the polymer/air interface of coating systems which can be chemically modified with desired properties (not solely biocidal) and is compatible with existing coating systems. Concentration of material at the air interface reduces overall additive requirements. By using the MT technology, 10-fold surface concentration enhancements have been observed. This saves money, is better for the environment, and minimizes negative effects on the base coating. While further applications are in development at the Army’s Aberdeen Proving Ground in Maryland, the basic technology offers new ways to enhance the performance of commercial and military coatings. A patent application has been filed. These MTs have the ability to transport a myriad of additives to the air/polymer surface of a coating, allowing the formulation of systems with new performance characteristics and the potential for reduced costs and overall loading requirements.

Extreme Temperature, High Load, Active Magnetic Bearings for Turbomachinery and ISG Applications
ARMY RESEARCH LABORATORY - ABERDEEN
Technology Overview The active magnetic bearing is a rotor support that uses magnetic force to hold the rotor in place as opposed to the forces of a rolling element or air foil bearing. Like other bearing types, the magnetic bearing can be characterized in terms of stiffness, damping, and load capacity, thus the forces that apply these properties are somewhat analogous for each bearing. As shown in figure 1, a magnetic bearing consists of multiple electromagnetic coils attached to a ferromagnetic stator. The coils are arranged such that opposite poles are adjacent, maximizing magnetic flux through the rotor. A ferromagnetic, laminated rotor stack is attached to the shaft to provide the flux path and attractive magnetic forces while minimizing eddy current formation. Position sensors are fixed a certain distance from the shaft, on the order of thousandths of an inch. The voltage output from the position sensors and subsequent signal conditioning relays position information to the microprocessor controller, which uses this information to produce a command signal. The command signal is transferred to a proportional current through power amplifiers and output to the magnetic coils, providing an attractive magnetic force to the rotor. Typically, control algorithms treat the rotor support system as a mass/spring/damper interaction on two axes, usually vertical and horizontal. The controller will output signals proportional to the shaft’s displacement from center. Advantages and Limitations Using a magnetic bearing for turbine engine applications results in three major technological advantages: oil-free operation with no air requirements, operation in extreme temperature environments, and active control. Proceeding from these advantages is a laundry list of desirable improvements to the turbine engine. They include reduced weight; no bearing contact, no wear, and less maintenance; operation in high altitudes; the subtraction of an oil, lube, and cooling system; bearing placement in the engine’s hot sector; shorter, thicker and highly damped shafts; blade tip clearance control and stall suppression; fault tolerance; control of shaft imbalance; and dynamic stiffness and damping. The magnetic bearing also enables integral starter-generator (ISG) technology that could replace the bulk, complexity, and cooling/lubrication needs of a separate shaft/gearbox driven generator.
