This research program is concerned with the design and fabrication of a novel head-mounted display system which utilizes foveal imaging techniques in order to provide eye limited resolution within a very wide, immersive field of vision. The application includes a “smart” allocation of high resolution imagery which is tracked to the user’s gaze point. This creates a system which is very eff ...

TECHNICAL ABSTRACT: Commercially available unmanned aircraft systems (UASs) are not well designed to meet requirements for many atmospheric measurement applications, including deployment from ships, long endurance, and low cost. Existing multi-rotor systems suffer from limited payload and endurance. Existing fixed wing systems offer improved endurance and payload, but require significant support h ...

Reducing the inert mass of propulsion systems in sample return spacecraft will reduce their launch costs and increase opportunity for these missions. Compared to a pressure-fed system, a propellant pump-fed system can significantly reduce overall propulsion system mass, especially for a system with high propellant throughput. To address this need, we propose to develop a compact, lightweight elect ...

DESCRIPTION (provided by applicant): This goal of this SBIR project is to quantify and validate the feasibility and potential for a non- obtrusive, wearable, in-shoe gait-monitoring device for children with Cerebral Palsy (CP). It is hypothesized that continuous monitoring and analysis of simple gait parameters in children with CP outside the clinical laboratory and during normal daily activities ...

Increased demands for electric vehicle performance have resulted in large power requirements and the potential for extremely large fault currents. This is true not only for over-the-road electric and hybrid vehicles, but also for ships and aircraft, which are increasingly moving toward all-electric propulsion. Without fast and reliable means to limit fault currents and isolate faulted sections, ...

To facilitate amphibious assault operations, the Marines need to quickly move amphibious combat vehicles (ACVs) between ships and the shore. However, due to an increased level of sophistication in the anti-ship weapons available to potential adversaries, Navy ships must remain far from shore during assault operations (i.e., many tens of miles). This creates a need for assault vehicles that can ach ...

The Army seeks to standardize all equipment on its battlefield logistics fuel, JP-8. JP-8 is difficult to use for small-scale, low-power applications, however, since its low vapor pressure and complex composition inhibit complete vaporization. Existing methods for vaporizing logistics fuels are not sufficiently controllable to support highly efficient catalytic combustion processes, or impose un ...

Ceramic matrix composites (CMCs) are desirable for high-performance aircraft engines due to their excellent strength-to-weight ratio and their ability to withstand high temperatures. However, CMCs are expensive to machine due to their low thermal conductivity, high hardness, and abrasiveness. Creare’s innovation is a novel Laser-Assisted Machining (LAM) system for high-performance machining of ...

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) produces neutrons that allow researchers to study key material properties. Neutrons are produced by the interaction of a very short (1 µsec), highly intense (1 MW at 60 Hz) pulse of protons with a flowing bath of mercury called the target. The process deposits a large amount of thermal energy in the mercury. Because mer ...

A Multimodal Acoustic Tool for Inline Pipe Inspection 3/19/2018 The US energy transport pipeline system is a longstanding distribution network with most of its still standing pipes being installed between the 1950s–1970s. Due to degradation mechanisms, such as embrittlement, capable of causing a two-fold reduction in fracture toughness, pipe rupture is a major risk. Current nondestructive ins ...
