Millimeter-wave RADAR imaging holds significant promise for many applications from rotorcraft DVE mitigation to standoff security screening. A key challenge of this imaging modality, however, has been the implementation of an effective method for creating an image without relying on either mechanical scanning or expensive, high SWAP phased array techniques. Herein, we present a concept for creat ...

To meet the critical security needs of the Department of Homeland Security and others, we propose two methods for providing a secure root of trust for mobile devices. One method is designed to integrate as easily into existing systems, while the other requires deeper integration but provides correspondingly stronger security. The keys to our work are practicality and integration: practicality to e ...

New enhancements to mobile computers including smaller sensors, displays and powerful processors have made them much more attractive for the battlefield, not only as wearable systems for soldiers, but also unattended ground sensors a warfighter can leave behind for situational awareness. Unfortunately, while the technologies for hands-free interfacing have improved greatly, the challenge of limiti ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

The Defense Threat Reduction Agency (DTRA) and the U.S. Strategic Command Center for Combating Weapons of Mass Destruction (SCC-WMD) requires transformational materials technology to support the intelligence, surveillance, and reconnaissance (ISR) of personnel and materials associated with weapons of mass destruction (WMD) development, manufacturing, and proliferation. Voxtel, Inc. proposes to fa ...

We propose that a comparative colorimetric assay be developed that will use a ticket of the same dimensions as the current ANP immunoassay tickets. This will allow the AChE test to be conducted using a similar workflow as the lateral flow immunoassay-based HHAs and be similarly read on the ANP reader to yield an unambiguous result independent of user judgment.

Low-light-level photodetector arrays are proposed for detecting the weak optical emission spectra from the trace atoms in the laser-induced breakdown spectroscopy (LIBS). The proposed semiconductor image intensifier and low-light-level camera utilize the miniaturized and monolithically integrated version of a proven solid-state detector technology, and is expected to be able to detect femto-watts ...

Preservation of the perishable food, especially fresh fruits and vegetables (FF&V), is particularly challenging due to substantial amount of refrigeration required to prevent spoilage. In the case of FF&V, the refrigerated air can quickly become contaminated with ethylene gas produced by the fruits and vegetables, which can lead to autocatalytic ripening of FF&V and accelerate spoilage even at id ...
