An atmospheric pressure chemical ionization mass spectrometer (APCIMS) will be designed to optimally measure a variety of gaseous species involved in marine boundary layer chemistry and condensation processes. The design of the instrument will modify prior technology, developed at the Geophysics Directorate of the Air Force Phillips Laboratory, to be included in the payload of a remotely piloted, ...

The new joint mission scenarios and stealth interdiction objectives for the U.S. Navy have resulted in the need for improved sensor systems for operations in the littoral environment. A High Frequency Towed Array (HFRA) sonar system, operating in the same frequency band as hull mounted systems, provides better detection, classification, and localization capabilities,and reduces ship maneuverabilit ...

Autonomous unmanned systems require provisions for fault detection and handling. Multiply-redundant schemes typically used in aerospace applications are prohibitively expensive for general applications, especially where low cost or small size are critical. A new strategy, proposed herein, offers the potential for low-cost fault-tolerant control of paramter-dependent systems that will be useful in ...

Prototype, wavelet-based lossy compression algorithms will be developed, for compression of both transient and narrowband sonar signals. An appropriate wavelet-related signal energy into the transform will be designed, with the goal of optimally concentrating 1 fewest number of coefficients. Standard 2-band wavelets will be examined, as well as M-band wavelets (M>2), wavelet-packets, and general p ...

A Variable Reluctance Machine - Electric Start System for an advanced ship propulsion turbine engine is offered as a replacement to the existing air turbine start system. The VRM technology is capable of producing the required starting torques for the turbine engine, while operating at lower nominal speeds. This will significantly improve start system reliability. The simple design, intrins ...

SBIR Technical Topic N95-038, Advanced Automatic Test Systems (ATS) Resources, addresses DoD's Joint Service ATS initiative to achieve a high degree of commonality and automation in the specification, procurement, design and application of standard ATS components across all DoD services. Two thrusts are seen key to meeting this objective in a cost effective manner: 1) identification of a tailorabl ...

Survivability of naval platforms in an important componenet in maintaining sea control and undersea superiority. Ship silencing efforts enhance survivability by reducing acoustic signatures. Active noise control provides an approach to signature reduction that can complement other means. This approach generally requires the use of multiple sensors to observe the surface response and multiple actua ...

We propose to develop ocean sensor components which will harmlessly biodegrade in a marine environment after performing their designed functions. These biodegradable components will meet or exceed performance requirements of existing non-biodegradable components. Our technical approach combines our vast experience with biodegradable and advanced high performance polymer processing with the experti ...

Abrasive blasting with sodium bicarbonate media is a choice replacement for degreasing with ozone-depleting 1,1,1 trichloroethane, but produces relatively large amounts of contaminated waste. The bulk of the waste consists of valuable resources, namely sodium bicarbonate with needs to be recystallized for reuse, as well as water. Removal of insoluable contaminations by flotation and settling is re ...
