RoadNarrows proposes a novel architecture to be implemented in a 6DOF vision system with applications in autonomous robotics. The system will report objects of interest along with location and pose information to a supervising computer. This system will be built around an advanced 3D vision platform that can deliver multiple video streams and 3D spatial measurements. The sensors will deliver high- ...

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 ...

ABSTRACT: This work proposes the design of a complete, compact, hybrid atom chip system for producing ultracold atoms, allowing subsequent control and manipulation of ultracold atoms using both optical and magnetic fields. Its emphasis is on optical lattice potentials and also complex potentials imposed by spatially varying magnetic and optical fields. Atom chips that incorporate optical windows ...

ABSTRACT: Mycotoxins are lipophilic agents derived from fungus that pose a significant public health problem around the world. The effects of mycotoxins include loss of human and animal life, increased healthcare and veterinary costs, reduced livestock production, and disposal of contaminated foods and feeds. Mycotoxins, such as aflatoxin and T-2 mycotoxins, have been reported to be weaponized as ...

ABSTRACT: Energy harvesting has emerged as a critical need for many current and future Air Force missions to enable their long lifetime requirements. Traditional approaches have focused on harvesting solar and vibration (i.e., via the use of piezoelectric materials) energy. More recently, substantial interest has developed in harvesting energy derived from thermal gradients (e.g., due to solar ...

ABSTRACT: This STTR Phase I feasibility study is a collaboration between Chiaro Technologies LLC (Chiaro) and the University of Colorado (CU). The program assesses the feasibility of a prototype holographic range-Doppler signal processor with a code-name"HORUS". The HORUS processor can take element signals from a large linear phased array to produce simultaneous range-Doppler maps across many an ...

ABSTRACT: The primary objective of the proposed STTR is to develop a low-cost, high performance material which is capable of directionally-tailored thermal emission and/or transmission control. By combining advanced electromagnetic band structure engineering techniques with low-cost, self-assembled fabrication methods, highly tunable, narrow-band emissivity control can be achieved over the entire ...

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: Boulder Nonlinear Systems recently developed and delivered a beam scanner that non-mechanically steers a monochromatic, 5-cm beam over an 80a x 80a field of regard (FOR) with sub-milliradian resolution. This prototype uses a transmissive, wide-angle stepper (coarse steering unit), which is very compact and easily inserts into conformal, sub-aperture assemblies. To provide high resolut ...

ABSTRACT: Tracking of objects orbiting the Earth is of critical importance for continued safe development and use of space. Particularly important are low Earth orbit (LEO) objects, since these make up the majority of objects in the space catalog. To track these LEO objects, accurate models of the dominant forces are needed. Besides gravity, the dominant force on LEO objects is atmospheric drag a ...
