ABSTRACT: The Space Plug-and-play Avionics (SPA) initiative is designed to improve the ability of the US military to respond to rapidly changing operational needs by creating, integrating, and launching a new spacecraft in less than one week. This would provide major benefits to war fighters on the ground, in the sky, and at sea. SPA-1 ASICs using I2C as the transport interface will likely be t ...

Existing silicon on insulator (SOI) pixel detectors which integrate single gate transistors with substrate diodes are limited by two key problems. First, the SOI transistor performance is degraded by the large potentials that must be applied to the substrate to fully deplete the diodes. Secondly, the performance of these SOI pixel detectors degrades with exposure to radiation due to charge trappin ...

Providing a reliable, clean and economical energy source is a priority of the US government. The challenge is to use coal, a secured and economical energy source, to produce clean hydrogen fuel to support domestic and global green economy with near-zero emission. Conventional separation technology and even developmental technology do not satisfy all of the requirements for hydrogen production from ...

Historical methods of reliability assessment are less and less effective as device sizes shrink. Larger sample sizes and longer duration tests are increasingly needed. At the same time, efforts to continue scaling semiconductors to ever smaller geometries is leading to an explosion of new device structures, materials and processes. The cost of testing these innovations is becoming a major barrier ...

Current technology for detecting long wavelength and very long wavelength infrared light, such as mercury cadmium telluride-based sensors, suffers from deleterious characteristics such as high noise and high cost. Creating detectors that operate in this wavelength range that reduce noise and cost will foster further implementation into remote sensing systems. SVT Associates proposes an innovative ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at the Stanford Linear Accelerator Center (SLAC), which is used in the current generation of photocathodes. Quantum efficiencies thus far are on the order of 1%, meaning only 1% of the photons hitting the photocathode result in the emission of an electro ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: Current air, ground and space networks are very dynamic with large-scale mobility needing human in-the-loop configuration to adapt to unforeseen situations. Humans and current automated systems cannot reconfigure consistently or fast enough. This leads to network performance not meeting mission needs. Airborne, space and ground networks are very dynamic, complex, and hard for the cur ...

The DoD has identified the need for airborne platforms from the various services to be integrated into the Global Information Grid (GIG). The current state of the practice for connecting airborne platforms to the GIG has four major limitations, i.e., (1) inability to adapt dynamically to topology changes in the network; (2) need for excessive manual configuration; (3) lack of scalalability with ne ...

As the DoD continues to"drawdown"the number of active duty personnel, there are a limited number of network operators to examine network status data and configure the large number of network devices present in any theater of operation. However, the ever increasing complexity of missions requires optimal network operation to provide mission assurance; this drives the need to maximize automation. ...
