Clinical monitoring of mental health status has not evolved much from the routine meeting between patient and clinician, which suffers from a lack of quantification, irregular and anecdotal reporting, and does not necessarily include input from family. This is unfortunate given current technology, in which people routinely volunteer to track their own health related behavior, such as exercise and ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...

We have developed a novel type of military obscurant that is based on the fabrication of composite particles with precisely defined geometries. These particles have very high infrared extinction efficiencies with peak extinction wavelengths that are directly correlated to the major and minor dimensions of the particles. By combining populations of particles, obscurants clouds can be produced that ...

We have developed a cost-effective process to improve the dissemination of particle-based obscurants. Surface coatings with defined chemical properties improve the obscurant dissemination characteristics by reducing inter-particle binding forces. This encapsulation method protects the particles from structural damage incurred during processing and dissemination, thereby improving their functional ...

This STTR project will develop and validate a robust, scalable computational capability for the simulation of weapon-target interactions of interest to the Army. The proposed algorithm is based on the FLIP (Fluid Implicit Particle) - MPM (Material Point Method) - MFM (Multiphase Flow Method) approach and CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory. CartaB ...

A suite of sensors is required to detect, analyze, track, and report position, speed, and direction of travel of watercraft in interior waterways. WaveBand's millimeter-wave sensors have demonstrated the capability to provide watercraft data whose attributes contain the position, speed, and direction of travel of these objects. The sensors are also capable of furnishing near-photographic quality ...

From consultations with the Army program manager, it was determined that the Army has a strong need for improved amplifiers in the W band. Accordingly, the proposed Phase II overall technical objective is to develop a 10 W, W-band prototype planar helix TWT. In Phase I, we addressed improving the repeatability, cost and yields of conventional Ka-band TWTs by introducing novel circuits, beam sou ...

This proposal is concerned with the development of an advanced three-dimensional simulation facility for the analysis of environments such as produced by high-velocity impact of kinetic energy penetrators under the Army STTR Program. This facility will enable the Virtual Testing and Design of Military Systems with increased survivability as demanded by the Army's Future Combat System (FCS) and Obj ...

Surface Optics Corporation (SOC), teamed with the University of California, Irvine, proposes an exploratory study aimed at the development of an inexpensive portable optical tagging system with an intelligent retro-reflective encoded tag, dynamic modulator, and sensors needed for tracking and identification of U.S. military assets. The encoded tag can be either affixed to, or printed onto, milita ...
