Diamond Antenna proposes to use Roll-Ringr technology and create a form, fit, and function Roll-Ringr replacement for the V22 slip ring. Unlike slip rings with a sliding electrical interface, Roll-Ringsr employ a rolling, non-sliding, electrical interface. The rolling, non-sliding, interface is a non-wearing, metal-to-metal, electrical interface that does not generate wear particles. Because th ...

About 15% of combat injuries sustained during conventional land warfare involve thorax wounds. Many intrathoracic wounds cause pneumothorax (PTX). PTX is clinically defined as a collection of gas or air in the pleural space, the space that surrounds the lung. This loss of pleural integrity causes the lung to collapse, significantly impacting respiration. A relatively simple procedure of chest tube ...

A system is proposed for early detection of hydrogen ingress and hydrogen-assisted cracking (HAC) in ship structures, using the unique capabilities of model-based sensor arrays. These MWM-Array sensors were used earlier in a preliminary demonstration to detect magnetic permeability changes during preloading and subsequent cathodic charging of an aircraft steel specimen having ultimate tensile str ...

Collecting and understanding marine bioluminescence (BL) distribution data is an important Navy requirement for strategic operations. Bioluminescence profile, spatial distribution, and temporal data can be used to understand the vulnerability of covert operations or to determine the detection threshold of hostile forces. Additionally, the low-cost collection and cataloging of this information wil ...

Recent world events have highlighted the need for timely and accurate intelligence data to assess threats and combat terror. An unmanned surface vehicle (USV ) can potentially perform intelligence, surveillance and reconnaissance (ISR) missions, provide force protection, hunt for mines in coastal waters or harbors, and provide port security. USVs under development by the Navy are powered by the ...

An advanced vector hydrophone towed array is proposed for surface ship torpedo defense applications. Vector hydrophone promise to provide much-needed array gain in aperture-constrained systems. The additional gain results in significant increases in detection ranges and/or decreases in false alarm rates. A physics-based vector sensor array simulator will be developed in a modular architecture. ...

A critical design feature for a towed mine countermeasure platform is low drag. In this STTR we propose to integrate an efficient acoustic source within a low drag body to perform influence mine sweeps behind an unmanned surface vehicle. To develop the optimum system a trade-study is proposed during Phase I to examine electronically-powered transducers and novel hydroacoustic concepts. The tran ...

We propose producing the MiDAS (Mission Displays for Autonomous Systems) interface designed to exploit existing automation capabilities of unmanned vehicles and improve future user interfaces in unmanned vehicles using an automated control system. Our technical approach features an innovative concept: using a Cognitive Work Analysis (CWA) approach to provide the structure for our design of the Mi ...

This proposal is concerned with the development of very long range acoustic communications (acomms) with submerged submarines with towed arrays . To achieve long ranges, we must move down from our conventional signaling above 10 kHz, to a frequency regime which imposes little attenuation on the signals. Based upon the availability of an extensive, well-documented long-range sonar data base, we p ...

We propose to develop an approach to combine model based reasoning with knowledge discovery techniques for enhanced Level 2 and 3 data fusion, especially suitable for detecting asymmetric threats (e.g. ambush, insurgency) in cluttered urban environments. The knowledge discovery part: 1) deploys evidence filtering of large volumes of intelligence data to detect low-signature significant spatio-temp ...
