This Small Business Innovation Research (SBIR) Phase II project will extend the applicability of the multi-environment probability density function (MEPDF) method to model turbulent combustion problems with realistic chemical kinetics within comprehensive Computational Fluid Dynamic (CFD) simulations of practical combustion equipment. The project aims to further advance the MEPDF method by extendi ...

This SBIR Phase II project addresses what is considered to be a significant unsolved problem in the Computer-Aided Design (CAD) industry; the fact that many CAD models contain numerous small, unwanted holes or gaps. These gaps occur most often along the seams where two surfaces in a CAD model meet, such as where a wing meets the fuselage of an airplane, and result from fundamental mathematical lim ...

This Small Business Technology Transfer (STTR) PhaseI project will design, fabricate, and validate a novel low cost (under $40/kW), robust and high-power-density 3 kW fuel cell (FC) power-conditioning system (PCS) suitable for lower voltage FC stacks, comprising a high-frequency inverter (HFI) followed by a forced cyclo-converter, which yields the following features: (1) 300 kHz switching frequen ...

A critical component of a biochemical sensor system for detection and analysis of airborne pathogens are mechanisms for automated acquisition and transport of an air sample from the sensor inlet to the analysis chamber. While considerable capability already exists for sampling and handling of macroscopic volumes of gas, formidable technological challenges needed to be overcome before microfabrica ...

Among composite materials, aluminum/graphite and copper/graphite composites are potentially leading materials for use in high-performance electronic systems. The use of aluminum matrix (Al/Gr) composites for packaging material, however, have been severely limited because of the raw material and fabrication costs of the composite. In order to produce an inexpensive packaging material that exhibit ...

A novel approach to the propulsion of very small, micro air vehicles is proposed in which electrostatic forces acting between an ion gas cloud and an appropriate anode are harnessed for thrust or lift. A means is proposed for the generation and maintenance of the ion gas from ambient air and for the regulation of the propulsor. Preliminary study indicates the new concept is valid only for air v ...

The project focuses on the development of a small, water-proof elecromyographic (EMG) sensor for a myoelectric arm prosthesis that transmits by a wireless link and can be easily and consistently installed over any muscle site. The wireless link eliminates wires and connectors inside the arm socket that can be bulky and unreliable due to corrosion and breakage of wires representing a significant i ...

Develops a small waterproof Warless EMG Preamp sensor for myoelectric arm prostheses that transmits a digital signal via a wireless link eliminating many of the wires and connectors associated with arm prostheses and allowing connection to modern rollon gel type liners
