The Navys submarine fleet uses 3 phase delta power per MIL-STD-1399/300B. The power distribution system is driven from two power busses and automatically transfer loads between the busses when one loses power. During bus transfer, a 70 100 msec power interrupt may occur which can create upset in the loads. PDAs proposed rack mounted 40 kW Power Supply Bridge (PSB) is installed between the power d ...

This Small Business Innovation Research Phase I program will demonstrate a novel chip-scale magneto-acoustic spin wave (MASW) circulator for use in S-band applications. The MASW concept is based on the velocity non-reciprocity of surface acoustic waves in Aluminum doped Nickel-Zinc ferrite. The program will first simulate and demonstrate the necessary concepts in a simpler, but no less critical de ...

The Navys submarine fleet uses 3 phase delta power per MIL-STD-1399/300B. The power distribution system operates most effectively when loading per phase is balanced within 3%. COTS data processing equipment used by the fleet typically needs single phase power, so balancing is achieved by manually assigning COTS items to power phases in a manner that equalizes phase loading. Assigning COTS items to ...

This Phase I program sets out to capitalize on recent advances in epitaxial growth of -Ga2O3 which have the potential to significantly improve upon the performance of currently available power electronics devices. Specifically, -Ga2O3, offers fundamental properties such as its ability to withstand very large electric fields that suggest its use as a power electronics material will lead to device p ...

Trusted Semiconductor Solutions proposes development of a flexible solid state disk (SSD) architecture that leverages state-of-the-art commercial non-volatile memories and integrates them into a compact, scalable device. The SSD will included stacked 3D NAND flash and a control module to access memory and communicate to the host through a standard communication interface present in Arm Group UAS. ...

The Army uses software applications and databases throughout its tactical systems to provide mission critical services. With mission software moving towards laptops and mobile devices in network disconnected environments, there is a need for a single-instance database solution which provides cell-level visibility with data provenance as information traverses the database. This will allow the Arm ...

Marines Maintainers using the Electronic Maintenance Support System (EMSS) to perform logistical support are currently constrained to the small liquid crystal display (LCD), which is ruggedized Panasonic CF-19 Toughbook known as the electronic maintenance device (EMD). Though it is very useful, the human factors of reading schematics optimized for presentation on paper sizes up to 22 in x 34 in (A ...

SIFT proposes to implement and validate GEMINI (Gestalt Mixed-Initiative Intelligence), a shared workspace for human-machine intelligence analysis that leverages human and machine cognitive strengths. Our Phase I prototype demonstrates the feasibility of the technology. GEMINIs information exploitation interface translates the users actions into structured knowledge and goals. It decomposes goa ...

Optical limiters (OL) protect sensitive optical and electronic devices from laser-induced damage. The existing passive OL utilize nonlinear optical materials transmitting low-intensity light, while blocking laser radiation with intensity exceeding certain limiting threshold (LT). The common problem with the existing OL is that, at any particular frequency range, the choice of suitable nonlinear ...

According to a 2014 study commissioned by the Department of Energy, hydropower from the more than 3 million untapped streams in the U.S. could potentially generate 65 gigawatts of electricity and help to reduce greenhouse gas emissions and pollution. However, the development of hydropower has been limited by several obstacles, as described by the U.S. Geological Survey: most of the prime locations ...
