Efforts to apply active noise and vibration control commercially, while intensifying, continue to be hampered by the cost of the computers required to implement the active algorithms. Currently, the cost of wide-band control is prohibitive for lightly damped systems such as precision structures or highly reverberant acoustic spaces, even if the system has just one canceling actuator and one error ...

In this Phase I SBIR we will design a series of ultra-wide angle fisheye lenses suitable for fuzing sensors and their related test equipment. The lenses will be customized to cover three spectral bands from 3 microns to 12 microns as well as the visible. There are many factors that will need to be taken into account including control of radial magnification or distortion over the wide 180 degree ...

The goal of this two-phase program is to develop a prototype system which addresses the problem of nondestructively extracting layout patterns for multilayer printed circuit boards. The system will use x-ray digital tomosynthesis for image acquisition, and advanced image processing, including morphological operators, to extract circuit features from the images. The objectives of Phase I are to 1 ...

This SBIR Phase I project proposes the development of a real-time IMU simulator which can inject simulated electronic signals into the GPS guidance receiver with least intrusion and is applicable to a wide range of navigation systems. The proposed IMU Simulator consists of a PC compatible microcomputer, a set of plug -in IMU signal generator boards, and a set of general purpose flight simulator i ...

We propose to develop a novel type of graphite with high nanoscale porosity by pyrolysis of the precursor embedded in layered clays, with the possiblity of varying the pore size and pore density. In Phase I, we will conduct a feasibility study of the process combined with a molecular modeling effort to predict the diffusion rate of lithium into the material as a function of its porosity. first, ...

In this proposal, we plan to synthesize UV-curable, fluorinated polycarbosilane (PCS) using fluoronation and substitution reactions. Conventional polycarbosilane (PCS) has been proven to be a good replacement for spin-on glass (SOG). PCS can be converted to a highly porous silicon oxide/oxycarbide composite at relatively low process temperature by controlling heat treatment temperatu ...
