Perhaps because it is the world's longest undefended border, smuggling is endemic across the our northern frontier with Canada. Since a 5,525 mile border cannot be effectively patrolled on foot, the Department of Homeland Security (DHS) must rely on technology to detect and track smugglers. Radio tomographic imaging (RTI) is an emerging device-free passive (DfP) localization technology that could ...

While most media attention in the wake of a terrorist attack, a natural disaster, or even a single building fire focuses rightly on the safety and wellbeing of the general public, one often overlooked aspect of these catastrophic events is the extreme risk taken by first responders who enter structures on the verge of collapse. For example, after the attacks on the World Trade Center on September ...

The proposed project is to demonstrate a novel technique for producing GaN single-crystal boules that yield GaN wafers and substrates suitable for fabrication of GaN high-power devices. The two key attributes of the proposed novel GaN growth technique (a bulk crystal growth technique) are: a high growth rate and an ability to achieve a superior crystal quality. The novel GaN crystal growth techn ...

In this abstract the development of vertical power transistors utilizing bulk GaN substrates with breakdown voltages of 1200V or higher, normally-off operation, and a drain current rating of 100A is proposed. These devices will feature vertical current flow, avalanche ruggedness, and a wide operating temperature range (-55 to 150°C). The target specific on-resistance for the transistor is 30x low ...

Mobile devices require security features that are utilized by application developers and users to ensure secure communication and commerce. Existing features on mobile hardware are often considered proprietary between the manufacturer and the telecommunications provider, rendering them unavailable for external use. Current works-around involve adding trusted hardware to the device, which increases ...

KWJ leverages its extensive experience to develop an automatic clandestine currency detection system (CCDS) for screening smuggled money in DHS real world applications. The ideal such system is equipped with probe (sampling, pre-concentration and detection), sensor array detection system or analytical instrument combination, analysis hardware and software, and communications components. The propos ...

In response to SBIR topic H-SB012.1-002, "Moving Target Defense", Ensighta Security Inc proposes to develop a binary program randomization tool based on advanced binary analysis techniques called Emerald. Current computer systems suffer from mono-culture where the same system is deployed identically on many machines. This makes it easy for attackers to replicate attacks across many machines. Binar ...

The implications of the proposed investigations are that radar systems already implemented for the automotive industry can be exploited, adapted and optimized for this application. These radar systems are inexpensive, of small size, employ advanced processing techniques which allow the tracking of threat targets, transmit low average power (10 milliwatts) and are proven to be people safe. We will ...

When responding to an incident, first responders often do not know what environments they will encounter at the incident scene. Although the garments that they are wearing may provide protection in their normal working environment, it may not be suited for unexpected conditions they encounter when they reach the scene of the incident, or as the incident progresses. Through this SBIR, Wizbe Innova ...

Sodium beta-alumina batteries are one of the most promising large-scale electrical energy storage technologies due to their high energy density and excellent cycling capability. Despite many advantages, the sodium batteries have several barriers for successful commercialization, mainly related to safety issues and high capital investment for installation. The current battery cells typically oper ...
