In Phase I Ceebus demonstrated the feasibility of an underwater, acoustic, direct-sequence spread-spectrum communication architecture, including actual data transfers and decoded message recovery. All of the communication algorithms were post-processed and communication was performed with a single piezo transducer. Prototype development is the next step in delivering a system that offers real-time ...

State of the art Radiation Hardened by Design (RHBD) techniques must scale down in feature size for radiation effects in 45 nm processes, and also scale up in complexity to support radiation fault analysis of VLSI circuits. Recent access to commercial 45 nm CMOS Silicon-on-Insulator (SOI) technologies has increased the interest in this technology for rad-hard electronic applications due to the in ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

We will employ the very latest methods in nanotechnology to realize vastly improved CO2 scrubbing efficiency in closed cycle underwater breathing apparatuse(UBA). Our system will occupy minimal volume, will be simple in design and will employ benign nano-particles as the CO2 active scrubbing material. Due to the design, CO2 uptake will be maximized and breathing flow resistance will kept at a mi ...

A need exists for a new environmental situational awareness sensor with multi-spectrum camouflage that is extremely small (90g) and capable of measuring with aviation-grade accuracy: wind speed/direction, horizontal visibility, sky condition, cloud heights, temperature, dewpoint, barometric pressure, precipitation and CBRN contamination. There exists a strong desire to support a variety of commun ...

A need exists for inexpensive, disposable, broadcast capable chemical / explosive-compound sensors that also provide site weather conditions. The state-of-the-art does not meet the need described both in terms of CWA sensor cost/size and lack of a low-cost deployment system. ADA proposes under this three-phased SBIR program to develop a system comprised of a suite of covert, modular, lightweight ...

Current methods of transmitting low-frequency RF energy from airborne platforms involve antennas such as blades that are electrically inefficient and a place a large aerodynamic burden on the airframe. SOCOM desires a method of efficiently transmitting low-frequency energy (VHF-UHF) at high power levels from airborne platforms. The desired gain numbers (-2 to 0 dB) at these frequencies would requi ...

The objective of this research is to develop beta versions of tools for automatically migrating radiation effects predicted in TCAD level tools to compact modeling tools. This transition will enable compact models that possess radiation effects to be quickly generated, which can then be used in circuit design activity. This approach is a substantial improvement over the current ad hoc approaches. ...

The single most effective method to thwart security threats posed by people with hostile intent is to detect their presence early. Unfortunately, large scale standoff detection of humans is difficult. Various sensors, including still and video cameras, have been designed and applied to human detection, however, to date a person is required to be in the detection loop since robust, automated detect ...
