In this proposal, we will develop a uniform framework, called a multimedia mediator, for integrating and querying multimedia data as well as heterogenous data located on a distributed network. The multimedia mediator will use distributed computing technology to scale up to real-world applications. We will develop graphical query languages and query engines whereby an end-user can query a system ...

AbTech Corporation proposes to apply its unique abductive information modeling (AIMTM) technology to develop a sensor fusion demonstration for command, control, communication, computer and information systems. Phase I is the necessary and sufficient precursor to an operational disparate sensor fusion for C4I applications. Phase I will show the feasibility of using AIM to model sensor data, threats ...

Accuwave Corporation has developed a narrow bandwidth (1/8 angstrom) optical imaging filter operating in the red. A critical need exists for narrow bandwidth imaging filters with a wide field of view. In this proposed research effort, Accuwave filter technology will be extended to a wider field of view using multimple holograms stored in a LiNb03 crystal.

Accuwave Corporation will study the feasibility of a volume holographic, phase-encoded optical image correlator for credit card and document validation and security application. Fourier transform holograms of a phase-encoded input image are stored using wavelength multiplexed holographic gratings in a photorefractive crystal. High spatial resolution images can be sotred with low crosstalk using ...

In this proposed SBIR program, Accuwave will investigate and demonstrate architectures for compact hologrpahic storage using materials and system innovations to reduce complexity and improve performance. Crosstalk, data formatting, input/output interfaces, and other relevant parameters will be characterized. Both wavelength and angle multiplexing, as well as its combination, will be used to prov ...

Accuwave Corporation will demonstrate a new approach to obtaining wide field of view imaging ( up to 15 degrees full angle) with a holographic grating filter. This new approach will make the filter element independent of the detector array dimensions, enabling resolution changes to be made without affecting the filter. This technique can also be extended to IR filters for use in eye-safe LIDAR s ...

The innovation proposed in this SBIR program is to develop a threat warning system against airborne laser radars in the blue-green transmission window. The proposed sensor system characterizes a sample through wavlelength, temporal, and spatial (theta fi) characteristics of the backscattered and source emission signals, enabling the air-borne laser radar to be identitied and tracked. The sensors ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200'C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metal, glass, and fil ...
