Abstract:Aspen Systems proposes to develop a novel process to increase the strength of sapphire at elevated temperatures. The resulting strength increase will alleviate the adverse effects of frictional heating of sapphire windows. Frictional heating can initiate a c-axis strength loss, leading to… more
Abstract:While the benefits of auxiliary heating of the human body when exposed to extremely cold temperatures are well known, there is currently no suitable technology developed to provide body heating in a completely autonomous and mobile system. In Phase I of the proposed program Aspen Systems will… more
Abstract:The proposed program will develop a liquid crystalline Adhesive with Zero Shrinkage, for bonding of airframe joints. Aspen Systems, Inc. is currently in the process of developing a new class of epoxide resins. These new epoxy materials are based on orderable, low molecular weight liquid crystalline… more

Abstract:A novel beamforming network is proposed to electronically scan two independent beams in a conformal phase array. The beamformer utilizes ferroelectric materials in the RF distribution network to control the amplitudes and phases of the array element excitations. One beamformer board is required… more
Abstract:The penetration of hyperspectral sensing from either airborne or spaceborne platforms into both commercial and defense applications, has risen the need for efficient data transmission and storage. This efficiency can be provided by data compression technology that exhibits sufficient compression… 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.
