We propose to carry out research and development of highly efficient broadband cryogenic switches using voltage controlled 2D electron gas in III-Nitride heterostructure field-effect transistors (HFETs). Unlike RF switches based on regular semiconductor devices, key characteristics of properly designed III-Nitride HFET - based RF switches will actually improve at cryogenic temperatures. These incl ...

Air Force operations often expose flight crew and support staff to unusual light-dark cycles that causes misalignment of the circadian pacemaker and sleep-wake cycles, resulting in disturbed sleep and impaired waking function. Air Force personnel are also frequently required to remain vigilant, often under conditions of acute or chronic sleep deprivation. An effective countermeasure is required to ...

The technical objectives of this SBIR proposal include the design verification of a frangible composite ILS Glideslope Tower that will maintain existing tolerances and mission performance capabilities. Zephyr Engineering Services’ [ZES’] (formerly All-Tech Solutions, Inc. [ATSI] ), technical approach is based upon the probability demonstrated through Phase I analysis that a qualified, frangib ...

To date, much government and industry effort has focused on passive board and chip coatings and self-destruct concepts, but as the DoD AT organizations have evaluated them, the effectiveness of these types of techniques has been limited. Other concepts that have been assessed by the AT community include manufacturing processes, obfuscation, encryption, active coatings, volume protection and other ...

The NESL concept uses three techniques to form a protective shield around modern computer systems. The first layer is a novel method for generating and locking cryptographic keys to a unique computer system. The second and third layer leverage this novel key system to protect primary and secondary memory from exploitation through encryption. The secondary memory system is protected with an encrypt ...

This work will continue the use of numerical methods to determine optimal design parameters for a compact hybrid fuel cell power system driven by a statistically determined load profile. Detailed physics-based models will be used to represent the bahavior of the components in the hybrid system. The components considered in the hybrid system for Phase II will be a PEM fuel cell, Li-ion batteries an ...

There is a need to better utilize the EHF band of frequencies including for battlefield, battlespace and mission specific uses. As reconnaissance and aerial surveillance capabilities continue to both grow and improve, increased bandwidth, high fidelity, high data rate communications are becoming essential. InnoSys, in conjunction with a major defense contractor, is developing and implementing hi ...

Autonomous Solutions proposes to increase the speed, accuracy, and overall effectiveness of currently fielded EOD robotic manipulators through 3D visualization and arm automation. ASI will integrate a 3D Flash Ladar camera onto an EOD robotic platform to enable the creation of a 3D model of the object of interest at the user interface. ASI will also implement autonomous arm control which will en ...

Ultra-dense integrated circuits with sub-10-nm features would provide enormous benefits for all information technologies, including computing, networking, and signal processing. However, it is widely accepted that a radical paradigm shift from purely CMOS technology to hybrid CMOS/nanodevice circuits is essential to achieve such level of miniaturization. We propose to work on a particular circuit ...

Compared to conventional power sources, fuel cell systems present such benefits as high efficiency, low emissions, long life, and near silent operation. Of the various fuel cell types, Solid oxide Fuel Cells (SOFC) have a number of advantages in hydrocarbon fuel applications because of their solid-state construction and high temperature operation. Presently, SOFCs operate in the temperature range ...
