Metalenses, with their ability to arbitrarily control the amplitude and phase of light across a band of wavelengths, have the potential to disrupt imaging and communication systems which rely on traditional lenses to focus, collimate, and otherwise manipulate optical signals, and are under increasing pressure to operate with reduced size and weight. We propose to design, develop, and demonstrate a ...

Metalenses, with their ability to arbitrarily control the amplitude and phase of light across a band of wavelengths, have the potential to disrupt imaging and communication systems which rely on traditional lenses to focus, collimate, and otherwise manipulate optical signals, and are under increasing pressure to operate with reduced size and weight with high performance over a large optical bandwi ...

DESCRIPTION (provided by applicant): Over 60,000 prosthetic grafts, which are comprised of either polyethylene terephthalate (polyester) or expanded polytetrafluoroethylene (ePTFE), are implanted in the United States each year. Medium (6-8mm) and small (l t5mm) internal diameter (I.D.) prosthetic arterial grafts continue to have unacceptably high failure rates when used in the clinical setting. T ...

DESCRIPTION (provided by applicant): Over 60,000 prosthetic grafts, which are primarily comprised of polyethylene terephthalate (polyester) or expanded polytetrafluoroethylene (ePTFE), are implanted in the United States each year. Unfortunately, these grafts continue to have high failure rates due to secondary complications associated with acute thromboses and incomplete, unregulated cellular prol ...

The first sentinel of ABL’s present target acquisition suite is a passive infrared search and track sensor of 1970s vintage, which we propose replacing with HyPAWS. HyPAWS is a low-cost passive wide-field of view staring sensor. Several such units suffice to provide full 360-degree view coverage. Leveraging revolutionary sensing techniques in ongoing development, HyPAWS offers advanced detect ...

UUVs have become increasingly important tools in the collection of environmental data. Their unique ability to operate independent of surface vessel conditions allows oceanographic seawater measurements when traditional means is not possible. Historically sensor packages for UUVs have been based on adaptions of ship deployed equipment. Recent development in sensors, such as the Hybrid Flow Through ...

Today's commercial video surveillance and monitoring (VSAM) systems are capable of producing enormous video streams that are over-whelming for human operators to review. But with automated intelligent interpretation of the imagery we can track and classifymoving objects of interest, collect spatial and temporal motion statistics, and detect anomalous behaviors. We propose to transition image under ...

In this program, Busek Co. Inc and Stanford University will develop and demonstrate a multi-mode high power plasma gun that can be used for both space propulsion and as a counter-measure against space debris or potentially hostile spacecraft. Investigations of this Coaxial High Energy (CHENG) thruster in the 1980's showed that it can damage a target. Because it is efficient over a wide range of ...

Busek Co. Inc. and Stanford University propose to develop and test an advanced high power plasma propulsion concept referred to here as a Coaxial High EnerGy Thruster, or CHENG thruster.  The thruster is first and foremost a propulsive device.  However, because the device is pulsed, compact, and efficient the plasma beam is highly condensed and energetic. For this reason, the thruster may also b ...
