Hemorrhagic shock is the leading cause of death in combat injuries. This application focuses on a novel way to treat hemorrhagic shock using a new device called the inspiratory impedance threshold device (ITD). The ITD increases blood pressure and survival rates in animals in hemorrhagic shock. Phase I studies in human volunteers are intended to demonstrate proof of concept that use of the ITD i ...

The intent of this phase 1 proposal is to demonstrate the feasibility of forced air convective warming to prevent hypothermia among battlefield casualties. The consequences of hypothermia for trauma victims can be severe, and the technical requirements of providing safe warming therapy in the field are challenging. Unfortunately while the need is great, no product currently on the market accepta ...

A critical military requirement exists for a fast, cost-effective, six-degrees-of-freedom (6DOF) technology that can track a pilot's helmet though rear-projection screens and is immune to distortion and interference from scatterers of magnetic/electrical energy. Building upon Phase I research that demonstrated feasibility of projecting light energy through graphics projection screens, Ascension T ...

The market for plasticizers is as much as 5 billion pounds world wide basis, 2 billion USA alone. Epoxidized Soybean Oil (ESO) represents 0.5 billion of the world wide market of these plasticizers, 0.15 billion USA. Pthalates are under investigation for toxicity. ESO (epoxidized soybean oil)plasticizers can not be increased in current formulations as ESO exudes when at levels beyond 5-7%. Develop ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this design cycle many times, with routine tasks performed by engineers in a trial-and-error manner. ...

Fabrication procedures have been proposed to develop biofilm-containing appliques capable of mitigating the corrosion of aluminum aerospace alloys (e.g. AA2024-T3). The proposed methods are expected to produce surface protective flexible polymer coatings that containing bacterial biofilms capable of providing corrosion protection to the metal surfaces of aircraft and other military equipment to wh ...

The multiple-view genlocked camera (MVGC) developed and demonstrated duringthe first phase of this program will be extened to the long infrared domain. In addition, real-time structure from motion (SFM) and video-based anvigation algorithms will be coded on the Phase I and Phase II ontrol computers. Captive Flight Tests in winter and summer conditions will be executed to gather data and to evalu ...

Space-based radar (SBR) requires multiple RF power amplifiers (PAs) to drive phased-arrays antennas. Control of the beam direction requires an amplitude range of 22 dB, and coupling between elements results in load impedances with significant mismatch. Both factors make conventional linear RF PAs very inefficient. The proposed approach employs a high-efficiency RF PA, class-S modulator, and e ...

The military makes extensive use of high-power signals at frequencies from 1.5 MHz to 3 GHz for communication, jamming, and other applications. The proposed ultra-wideband high-efficiency power amplifier is based upon a combination of a high-efficiency RF power amplifier (PA) and electronic tuning. The high-efficiency PA provides maximum power output and minimum power consumption, thus allowing ...

The objective of this proposal is to improve Army logistics by permitting the use of diesel engines capable of operation on heavy-hydrocarbon fuels including DF-2 and JP-8, instead of gasoline engines, for small mobile generators and other small motor applications (e.g. utility pumps), thus reducing Army fuel/ fuel distribution costs. Normally, diesel engines do not have sufficient power density ...
