Abstract:A diagnostic technique is proposed for measuring temperature and velocity simultaneously in a high temperature reacting flow for aiding research in propulsion. The technique involves seeding particles of a ceramic thermographic phosphor into the flow and illuminating them with two overlapping pulsed… more
Abstract:A diagnostic is proposed for aircraft engine exhausts that provides three velocity components at each point in an image of a slice through the plume. The method measures the Doppler shift of laser light scattered from soot particles naturally present in the exhaust, and may also be useful for… more
Abstract:A non-intrusive sensor will be developed for detecting metals in the plume of a liquid hydrocarbon-fueled rocket engine for monitoring engine health. Conventional passive emission sensors have proven to be useful in the detection of metal combinations that uniquely identify a failing component in… more
Abstract:Two optical methods are proposed for the detection of a range of types of damage on coated and uncoated airfoils in advanced gas turbines, by means of borescope inspection of on-wing parts. The techniques are based on low coherence interferometry and luminescence spectroscopy. The Phase I work plan… more
Abstract:To address this HSARPA need, Physical Optics Corporation (POC) proposes to develop a new Visor-Enhanced SCBA Transparent
Armor (VESTA) lens, based on a transparent metallic-oxide material system, and serving as a drop-in replacement lens in current
mask systems. VESTA possesses improved… more
Abstract:To address the HSARPA need for a next generation helmet with an embedded heads up display for personal situation awareness for emergency
responders, Physical Optics Corporation, POC, proposes to continue the development of the Helmet Embedded Conformal Augmented Display,
HECAD, system. The HECAD… more
Abstract:DESCRIPTION (provided by applicant): It is widely know that if retinopathy and specifically diabetic retinopathy are not duly detected and controlled through medical interventions, they can progress into a proliferative retinopathy and cause significant decrease in… more
Abstract:DESCRIPTION (provided by applicant): Mining accidents are still a regular occurrence, often resulting in the loss of dozens of lives. Many of these fatalities could have been averted had there been a reliable emergency communications system in place to provide life-saving information to… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
