"We propose a directional, broadband, highly efficient underwater acoustic transducer using a baffled cylinder made out from piezoelectric single crystals. The prospective application areas will be for an underwater acoustic modem communication andAutonomous Underwater Vehicles (AUV), in which high efficiency of the transducer system is required due to the limited energy availability (battery) an ...

"This proposal is for the development of a high sensitivity pressure gradient acoustic motion sensor (accelerometer) of the flexural plate type using piezoelectric single crystals. The pressure gradient acoustic motion sensor is based on flexural plateelements operating below resonance in the accelerometer mode. The high piezoelectric coefficients for single crystals is ideal for increasing the ...

"Proposed work utilizes three existing fourth-generation modules of the cylinder kit model which applied to improving oil consumption, blowby and general engine life in gasoline and diesel engines for over thirty years. When completed, the proposed Phase 1work will:,h Link the three independent modules:- Ring motion, gas flow, oil film thickness, and friction- Calculation of void areas between r ...

"The objective of this project is to develop an expansion chamber/exhaust muffler system which will optimize the fuel economy/power density of small two-cycle compression engines while simultaneously providing 16 db or greater noise reduction.State-of-the-art validated computer models will be employed with the objective of minimizing the number of experimental iterations required to achieve the ob ...

"Coprime proposes to investigate the applicability of learning-based source separation methodologies to the problem of multiple targets in a complex acoustic environment. The Phase I effort will focus on identifying viable learning-based source separationalgorithms specifically tuned to the multiple combat vehicle scenario. A prototype architecture will be developed and numerical software rapidly ...

"Recent advances in remote sensing technologies through the availability of more sensitive instruments, and improvements in geo-location technologies and analysis software have resulted in significant strides in the successful application of high resolutionremote sensing to feature identification such as soil disturbances. These strides have been achieved by field-oriented remote sensing experts, ...

"In Phase I Production Products designed a polyurethane shock andvibration mount system, fabricated prototypes, performed loadstroke and shock testing, analytically predicted shock andvibration performance, and demonstrated the ability to meetanalytical predictions. Shock mount designs were subjected toshock tests to over 200 g's with an overall reduction in maximumacceleration of a factor of over ...

The proposed is an buoyancy control module based on the "Cuttlefish". It substitutes man-made Smart Material and MEMS technology to duplicate capabilities occuring in nature.The proposed strategy would emulate the functionality of the Cuttlefish and its natural capability to maintain neutrally buoyancy. The solution is envisioned as a smart Micro Fluidic Control System that would be etched into ...

Next generation of advanced weapon systems and platforms, such as the Future Combat System Multi-role Cannon and Munitions Suite require low-cost embedded wireless sensors and actuators with data communication / command capabilities. With the growing needof sensors the powering and communication with them becomes a critical factor. Applications often require such devices to be completely embedded ...
