There are many commercially available flexible hoses for use in non-rigid coupling of hydraulic, air, and other piping systems. However, these systems are currently not designed for operating under severe hydrostatic and dynamic pressures experienced by Deep Submergence Systems in their extreme operating environments. The pipes that connect the DDS to the sub are exposed to the water and experien ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

NIST is using a sensitive optical technique called cavity ring-down detection to permit detection of impurities in semiconductor process gases, which cause substantial losses in manufacturing yield. In order to increase the sensitivity and range of application of this technique, improved single frequency laser sources are required. In particular, lasers providing more power, narrower line-width, b ...

Aculight proposes to develop a laser source that will enable NIST to perform highly sensitive water vapor detection via cavity ring-down spectroscopy. The source will operate over a wavelength region centered at 1380nm. It will be based upon frequency conversion of a single frequency fiber source using an optical parametric oscillator (OPO).The performance of the source in terms of several critica ...

SOCOM, other military branches, and civilian authorities (homeland defense) need ways to rapidly determine the presence of chemical and biological threats and classify their nature. Standoff detection of the threats would greatly enhance personnel safetyand allow more operational flexibility.We propose a novel laser-based system allowing remote measurements of the infrared spectra of aerosols, va ...

Accelerated development of directed energy technologies has presented new problems to mission planners and weapon operators regarding the capabilities, lethality and performance of weapon systems. The Emerging Weapons Technology Evaluation Model willaddress these shortcomings by providing users of varying technical expertise 1) the ability to model a variety of weapons in various mission scenario ...

The Directed Energy Tactical Mission Application Code (DETMAC) is a mission planning simulation tool to model directed-energy weapon capabilities, target vulnerabilities, and environmental constraints. It will be used by mission planners to visualize an entire mission timeline and prompt development of optimal tactics, techniques and procedures for successful employment of new weapon capabilities ...

Connecting deep submergence systems (submarines) in the field can be a dangerous and difficult task. The rigid piping systems used today have little flexibility to accommodate for variations in connection points and differences in tolerances between vessels. Atkins & Pearce, a 200 year old textile processing company, has developed a technology that uses a multi-layered approach to create a high ...

B.E. Meyers & Company proposes to deliver the Phase I requirements of the AVPAS by utilizing its research and development resources to examine new technologies, architectures, and designs. These efforts will result in providing to the government the market research, proof-of-concept analysis, and a proposed design for an AVPAS prototype. The prototype design will be founded on incremental testin ...

The Temperature Programmed Sensing (TPS) system developed at NIST presents many opportunities and unique challenges. The data output from the system can be quite complex and there are many opportunities to optimize the system for specific sensing scenarios. We propose a program aimed at characterizing the system so that potential problems (such as system drift) can be solved early so that the full ...
