The goal of this program is to apply recent advancements in the growth of piezoelectric single crystal materials to build ultrasound transducers with very broad bandwidth, which can improve and simplify ultrasound imaging for combat casualty care. Relaxor-based ferroelectric materials of PZN-PT and PMN-PT have been shown to have coupling factors for some modes of over 90%. Transducer modelin ...

Advances in laser based weapons constitute a real threat to military aircraft. Detection of incident laser beam illumination early enough to allow an active response is vital. A laser beamrider detection system must have a high probability of detection with a low false alarm rate. This proposal addresses the difficult problem of detecting hostile laser illumination against bright daylight backgro ...

To obtain high quality or multi-spectral imagery from moving airborne platforms power- ful processing techniques are employed to remove the effects of aircraft forward velocity. A dynamically moveable imaging system which compensates for aircraft motion would greatly simplify these corrective requirements, and allow post processing systems to focus on target identification rather than "cleaning up ...

An innovative combination of key contributors to ejection seat/capsule aerodynamic modeling, controller and sequencer design, and biodynamic simulation are to be integrated under the framework of a commercial software simulation tool for this Phase I project. The use of a commercial simulation package enhances the cost effectiveness of the software development, since support of graphics capabilit ...

Ultrasonic imaging is the preferred method for noninvasive tissue examination and real-time blood flow analysis. Foreign items (e.g., radiolucent shrapnel) embedded in the body can also be imaged. While this would greatly aide combat field medics and civilian emergency medical technicians, current ultrasound scanners are too large, heavy, and power-consumptive for battery operation. Major scan ...

This proposal describes a program to identify, simulate and test oxide-based intracavity structures to optimize stable single-mode emission in vertical-cavity surface emitting lasers (VCSELs). Laterally-oxidized intracavity layers will be tailored using Picolight proprietary methods to optimize efficient single-mode emission in a manufacturable process. The Phase I objectives include: 1) sp ...

Capturing color visible imagery in low light is becoming extremely important in both military and commercial applications. Currently, both military and commercial requirements for low-light-level applications are met with image intensifiers coupled to charge-coupled devices (CCDs). These systems do not provide color images and suffer from degradation of contrast, resolution, and signal-to-n ...

The proliferation of GPS into weapons systems provides an opportunity to establish a wireless data interface into GPS guided weapons. The proposed design builds on an Open Systems Interconnect (OSI) model to provide a generic network architecture that takes advantage of existing standards in data communication to facilitate integration with the Military Information Structure or C41 network. Under ...

The ultimate goal of the proposed R&D is to design, develop and validate innovative CORBA-based software security services and compatible hardware architectures which provide high assurance for multi-level secure (MLS) network applications. The proposed approach is innovative in that it is based on the emerging OMG Security Services Specification (SSS) plus a proprietary technique for maintaining ...

A non-polluting efficient cleaning technology for completely removing clogging buildup and microbial biofilm from ultrafiltration membranes has been developed. The technology has been successfully applied to synthetic non-oily graywater effluent and should meet all regulatory standards for discharge. The technology should also be applicable to blackwater applications. It consists of three element ...
