We propose a wireless (HF band) network integrated with existing wireline network system which could be used as an extension of the wireline network. The system should handle both voice and data, should conform to the existing and future wireline protocols, could be easily reconfigured and should provide robust and secure means of communication in battlefield and in areas where wirelines do not ex ...

Medical outcomes analysis can be used for treatment plan recommendation, physician training, organization and budgeting of health care programs, and for resource allocation. Objectives are to apply the following disciplines to outcomes analysis: Information theory, optimization/control theory, sequential hypothesis testing, and parallel, distributed processing. Utility/loss measures are presently ...

ARPA has indentified the need for compact and mobile air sampling equipment with two uses: as a weapons of mass destruction (WMD) monitoring systems or as an air pollution detector. PHI proposes to meet these needs with a novel Raman Scattering and Flourescence instrument using a diode laser and a charge coupled device (CCD) or avalanche photodiode (APD) detector. The instrument selects the Raman ...

SDL, Inc. (formerly Spectra Diode Laboratories) proposes to develop a low-cost optical fiber amplifier for 1.3 um optical fiber systems. Although the development of 1.55 um Er-doped fiber amplifiers have revolutionized 1.55 um fiber communications, the vast majority of installed fiber systems is designed for 1.3 um transmission, and there is no existing fiber amplifier technology that can address ...

The use of MCTs in a high-frequency, high-power motor controller requires soft switching. While MCTs are known to possess significant forward drop advantages over IGBTs or MOSFETs, their switching behavior is much more complex. Conventional PWM switching of MCTs at high frequency leads to significant switching losses due mostly to a current tailing problem during device turn-off. Zero-voltage swit ...

Automated processing of sensor/signal data and other non-sensor information provides substantial force-multiplying benefits. The timely and cost-effective leveraging of these types of information provides a significant advantage over adversaries not possessing comparable information processing capabilities. The intelligent processing of diverse types of data provides a target assessment technology ...

The objectives of this program are to study the partial or complete conversion of small diameter, high strength carbon fiber multifilament tows to SiC and to understand the relationship of the conversion mechanisms to the morphology and properties of the resultant fibers. The project will utilize chemical vapor conversion processes in combination with a novel electromagnetic spreading technique fo ...

We proposal the development of a protable, wireless, addressable device for simultaneously monitoring the physiological status of remotely located patients. The development of this device will facilitate more cost effective medical care, and as such promises to revolutionize the delivery of medicine. The improved ability to remotely monitor the vital signs of injured individuals using this device ...

Traditionally, the recording of high speed phenomena has required the use of film cameras; though providing very fast frame rates and high resolution, film is bulky, heavy, expensive, and requires considerable processing delay before the results from an event can be viewed. In recent years, advances in solid-state imager design have made high-speed video a viable alternative to film. High speed vi ...

Application of silicon microfabrication technology to biodiagnostic consumables offers the potential advantages of sub-microliter sample size, immediate test results, and lower cost. Such microelectromechanical systems (MEMS) are limited in achieving their full potential by the present manual methods of drawing a blood sample and using only a small aliquot for the analytical procedure. Our goal ...
