Oceanit proposes to develop a low cost, reliable, wireless mesh networking system that will enable remote monitoring and tracking of sensors on emergency responders in hostile building environments. The heart of the system will use a commercial-off-the-shelf (COTS) wireless mesh networking IC platform for low-power and low-cost communications. By using a wireless mesh network, low-power wireless t ...

Hand-held gamma ray spectrometers are a vital tool for detecting and identifying nuclear materials to counter the threat of radiological and nuclear terrorism. The HPGe crystals in these detectors must operate at cryogenic temperatures to achieve good energy resolution. We propose to develop an innovative, miniature cryogenic cooling system that will be ideal for hand-held detectors. High efficien ...

Surveillance systems record spatially and time-referenced sensor data, such as video imagery. With a growing need to monitor larger regions for longer intervals, there is a corresponding geometric growth in the size of the four-dimensional time-space surveillance recording. Tools that allow efficient exploration of this time-space are key to extracting value from the surveillance data. The critica ...
