The objective of this proposal is to demonstrate the feasibility of the application of a patented microwave scanning device as a portable NDE methodology to perform monitoring of the health of ceramic armor from non-projectile impacts. The scanning process utilizes microwaves as an interrogating beam to penetrate a dielectric material. The microwaves combine and form an interference pattern that ...

AGILTRON proposes to realize a new MEMS energy scavenger capable of powering in-situ micro sensors and their wireless modules under harsh operational environments. The design overcomes current shortcomings and achieves sufficient power output, reliability, miniature size, and low cost. The approach incorporates several innovations including stable electromagnetic structure, efficient power generat ...

Wireless sensors promise to reduce the Navy’s aircraft maintenance costs via real-time monitoring of corrosion-prone components. The promise of wireless sensors lies in their reduced susceptibility to failure, reduced weight and configurational flexibility compared with conventional wired sensors. However, because of the costs of replacing batteries in sensors deployed in inaccessible locations, ...

The objective of this proposed effort is to demonstrate the feasibility of Vibrant Corporation (Vibrant) improving current non-destructive evaluation (NDE) methods to allow for surface and subsurface feature inspection of hybrid bearings. Under the proposed effort, an NDE capability will be developed and demonstrated that can quickly and cost effectively detect various types of manufacturing defec ...

Due to the remarkable benefits provided by 802.16 Broadband Wireless Access (BWA) networks, military interest in such technology has consistently grown. However, preplanned base station locations with tall towers and directionally-optimized antennas are not tactically useful. Therefore, in order for the military to leverage commercial wireless technologies, these technologies must be adapted for a ...

As a result of the environment in which they operate, Naval aircraft are subject to pervasive corrosion damage. On-board sensors can signal when corrosion may be occurring, but there is a need for a portable corrosion scanning system that can confirm the degree and location of actual corrosion damage. JENTEK’s patented Meandering Winding Magnetometer sensors and arrays (MWM-Array) have prove ...

A class of high amplitude and high bandwidth actuators called localized arc filament plasma actuators (LAFPAs) have recently been developed at OSU and used for control of high-speed and high Reynolds number jets. The control included successful noise mitigation in a Mach 0.9 jet and mixing enhancement (and very preliminary results for noise mitigation) in a Mach 1.3 ideally expanded jet. The contr ...

Fatigue lives of rotating engine components are greatly enhanced through application of shot peening and other processes that impart residual compressive stresses to their surfaces. X-ray diffraction measurements, however, confirm that these stresses relax during service. Furthermore, residual stresses may relax rapidly or gradually and can vary by location. This proposal addresses the need for ...

Physical Sciences Inc. proposes a novel technique to subtract background spectra from the spectra of interest and to then combine the LIBS and Raman spectra for remote explosive detection. Our approach uses support vector machines with transductive inference for training. Based on our experience we anticipate a 95% correct identification of explosive vs. non-explosive material. Further, our calcul ...

Until recently, gas lasers were the only technology that could provide the powers required for Directed Energy (DE) applications, such as providing area protection to Army forces against rockets, artillery, and mortars. Recent advances in solid state lasers have shown their potential for power scaling to DE levels, and their lack of expendables is major advantage over gas systems. To date, the sol ...
