Job related hearing loss is a growing issue with active and retired military personnel. Ear protection is critical to prevent such injury, but personnel in variable pressure environments, such as pilots, often cannot use the best hearing protection due to pressure changes risking barotrauma. Current physiological monitoring systems can measure in-ear pressure levels, but require customized ear pie ...

SI2 Technologies, Inc. (SI2) will develop a lightweight spectrum monitoring payload for the ScanEagle unmanned aerial vehicle (UAV) with custom wideband antennas and a lightweight low power electronics package. SI2 will leverage recently flight tested wideband technology developed for the RQ-21a Blackjack to provide instantaneous coverage of the full band of interest with a minimal number of sub-b ...

The predictive understanding of Radio Frequency electromagnetic propagation is critical for the performance of Navy systems. To acquire the necessary data, the Navy needs a system integrated with the ScanEagle Unmanned Aerial Vehicle (UAV) capable of analyzing distant signals of opportunity while meeting strict Size, Weight, and Power (SWaP) requirements placed on hardware payloads. To meet this n ...

The US Navy faces several limitations when planning operations in regard to forecasting environmental conditions. Currently, mission analysis and planning tools rely heavily on short-term (less than a week) forecasts or long-term statistical climate products. However, newly available data in the form of weather forecast ensembles provides dynamical and statistical extended-range predictions that w ...

Future hypersonic vehicles will be required to fly extended, long term trajectories where the bod-ies must exhibit high lift-to-drag (L/D) ratios. The need for reduced drag means that the nosetips and leading edges must have small radii, shallow wedge angles, and be erosion resistant. Desira-ble dimensions include a nose radius on the order of 0.040 inch and a wedge half angle of about 3. This rad ...

This SBIR Phase I Proposal addresses the need for a wide-angle beam steering array with piezoelectric single crystal Tonpilz transducers. The objective is to design, build and test a sub-array of piezoelectric single crystal Tonpilz SONAR transducers that can be steered over large angles with high directivity and low side lobe levels. These objectives will be accomplished through not only experime ...

Navy systems maintainers are being asked to maintain increasingly complex systems with fewer maintainers and, therefore, less time for each task and less mentoring from experienced maintainers. Current training practice is not sufficient for this environment because it does not focus on creating robust, adaptable skills that give the trainee background knowledge and troubleshooting experience to s ...

Navy technology is exquisitely complex, and thus difficult to diagnose and repair. Acquiring and, more importantly, retaining the technical skills for corrective maintenance of these complex systems is a significant challenge for the Navy. What is needed is an efficient technology for assessing, training, and retraining diagnosis and repair skills among technicians who maintain complex shipboard s ...

The goal of this Phase I program is to develop broadband single crystal sonar for the ATT. Single crystal piezoelectric is a high energy density, highly efficient piezoelectric material that is being used to develop acoustic and ultrasonic transducers with bandwidths much higher than has been possible with conventional ceramic materials. For sonar, broad bandwidth is especially important for opera ...

TRS Technologies, Inc. proposes to develop volume efficient, fast discharge, high breakdown strength capacitors with stable dielectric properties for utilization in pulse power systems. The proposed ceramic capacitor will combine the best features of high energy density, low dielectric loss and high reliability. The capacitors developed on this program will have an energy density >0.6J/cc, low pow ...
