Wide-Area Infrared Imaging (WAIRI) System for Person-in-Water Detection

State-of-the-art turreted infrared imagers can stream high-definition, dynamically sensitive, telescopic video to users searching for a person in the water (PIW). This capability has not yet been matched, however, with automated detection systems. Search rate and detection probability are currently limited by the capacity of human users to visually process and interpret video data rapidly. Fatigue, distractions, and recognition time are limiting factors. Lynntech has conceptually proven an automated system, WAIRI, which acquires and analyzes thermal data over a wide field of view for PIW detection. The system continuously determines likely targets within the wide field of view and presents them sequentially to a human user at high image magnification for identification. Phase I scaled testing demonstrated 99 percent detection probability for a PIW in sea state 3 conditions at a search rate of 360 km2/hr. Additionally, the system was both highly resistant to solar glint and able to detect hypothermal targets. Production of a flight-operational system and live, open-ocean PIW search testing will be conducted in Phase II. Low implementation costs and ease of integration with existing airborne turreted infrared imagers significantly enhance commercial viability. Potential customers include rescue, police, and military agencies.

CNT-Based D2 Ion Source for Improved Neutron and Photon Generator

Applied Nanotech, Inc. (ANI) proposes to develop a novel field ionization technology to produce a deuterium ion (D+) current for a neutron source or r-ray source enabling fast switching, high repetition rate and high yields. Carbon nanotubes (CNT) have a high aspect ratio structure (they are long and narrow) that induces high electric field concentration, thus they are ideal choices for electron field emission, electron field desorption and field ionization applications. In Phase I, the ANI team demonstrated the feasibility of a field ionization CNT-based ion source for neutron generator applications. We demonstrated an ion source that can generate about 1 uA/cm2 with variable pulse width and short pulse cut-off time (< 4 usec). In addition we demonstrated neutron generation using this approach with count rates greater than 3o above background levels. This Phase II program is intended to improve the ion source by achieving higher current densities (needed to make the source small to be competitive with existing COTS neutron sources), longer life and high atomic ion ratio. The program is also intended to design, build and demonstrate a neutron source with a yield of at least 107 n/sec, sufficient yield to show that this source approach can be scaled to higher yields with a design that is simple and inexpensive to manufacture.
