For Phase I, an ultra low power, high performance microprocessor core using a combination of double-gated and independent double-gated Flexfet™ SOI CMOS technology from American Semiconductor will be designed to address the requirements of military and space communication systems. High integration feasibility using Flexfet technologies followed by confirmation of the power and performance improv ...

We propose to implement a novel countermeasure against the exploitation of integrated circuit hardware. The proposed countermeasure is applicable to both FPGAs and ASICs, increases design obfuscation and promises to block embedded hardware exploits. It also is fully compatible with virtually any other hardware exploit countermeasure and reduces forensic costs when exploits are suspected. The propo ...

The proposed effort in Phase II is to develop, produce, and demonstrate a prototype inspection platform and complementary damage modeling tool as a complete nondestructive evaluation solution referred to as the X-Ray Corrosion Detection System (XCDS). This system will be based on the state of the art radiographic techniques including narrow-bandwidth, spectral, and phase-contrast radiography, as w ...

Current life prediction methods, such as AGMA, are empirical-based, deterministic in nature and cannot consider the effects of gear manufacturing processes, material microstructure and lubrication on fatigue strength. The estimated life is as good as the information entered by the user and it requires considerable design, manufacturing and field experience. In addition, current methods cannot take ...

The Arnold Engineering Development Center has witnessed vibration anomalies on facility equipment that have raised concerns about possible catastrophic or costly failures. In response, AEDC is seeking an advanced, comprehensive condition monitoring system to provide accurate and timely health information; information that will allow AEDC to foresee and avoid unexpected, and possibly catastrophic ...

Sentient will adapt its existing prognostics and health management software and architecture, called SAGE, to Navy unmanned aerial vehicles (UAVs). SAGE is particularly well-suited for UAVs because it already incorporates a centralized architecture, where data storage, signal processing, data management and visualization, higher level reasoning, prognostics, and maintenance and logistics coordinat ...

Sentient will develop enhanced fretting fatigue analysis software with rigorous consideration of surface roughness effects in the stick/slip phenomena and fatigue. This will be coupled with an analysis of the stresses and resulting degradation in the material. Sentient will utilize diagnostic data in the form of vibration measurements and/or measured shaft torque to determine the loading condition ...

Gear tooth surface fatigue (pitting) is common precursor failure mode that leads to excessive gear vibration, liberation of debris particles that damage ancillary components (e.g. bearings), and serves as crack initiation sites that lead to eventual catastrophic tooth failure. Current gearbox life estimation techniques commonly underplay the significance of gear tooth surface fatigue due to the co ...

"This proposal is for a (Metal Insulator Metal) MIM multilayer capacitor design that achieves higher capacitance density through the use of large electrode surface area within a small chip dimension utilizing a high-k dielectric in a multi-Damascenefabricated approach consistent with low temperature process requirements. Capacitors, either realized as discrete elements in thin-film technologies, o ...

"Low cost, high-frequency, radiation-tolerant wafer fabrication for next generation electronic circuits is limited by domestic manufacturing capability. General availability of inherently radiation tolerant silicon-on-insulator (SOI) process technology tothe fabless design community is limited to only one viable domestic source. This proposal presents the opportunity to create U.S. foundry manufa ...
