During Phase I of this SBIR effort, D-STAR Engineering aimed to combine the best features of an electric-motor powered Micro Air Vehicle (e-MAV), and a micro-diesel engine, and explore the development of a JP-8 fueled hybrid diesel electric propulsion system for use on small unmanned aerial vehicles (UAVs). D-STAR had identified two approaches for development of such a hybrid-electric UAV : A lon ...

The DARPA Phraselator currently deployed in overseas military operations is capable of translating spoken English language phrases into audible Pashto, Urdu, Dari, and Arabic language phrases. Although usable, the Phraselator is highly vulnerable to typical military environment noise resulting in significant loss of accuracy due to the limitations of existing microphone technology. Therefore the ...

This program will provide a key manufacturing breakthrough for high-performance inexpensive miniature SEMs. We plan to develop a MEMS, microassembly-based, fully functional mini-SEM having 1/10,000 the volume of current units. Zyvex is a dynamic small firm with a highly qualified technical team, experienced management, and the advantage of a $25M / 5 year NIST-ATP award that is funding the continu ...

The Phase I SBIR program has successfully responded to a critical need in the MEMS community -- demonstration of a means to fabricate a fully integral micro power supply, where an energy scavenger (e.g., photovoltaics or RF device), energy storage device(battery, super capacitor, etc), and control circuitry (fuzzy logic-based, as proposed here) can all be fabricated in a single manufacturing opera ...

We propose to build a rugged, low-cost fluorescence and aerosol lidar for detection and identification of bio-agent aerosols. By utilizing digital detection several orders of magnitude improvement in lidar performance is achieved, resulting in a muchsmaller lidar with superior range and sensitivity compared to analog detection lidars. The feasibility of fluorescence portable digital lidar was es ...

We propose to develop a rapid prototyping/manufacturing technology for the direct-write fabrication of optical components, including GRIN (Gradient index of Refraction) lenses up to 6 inches in diameter. We will build a GRIN Lens Printing Platform whichwill utilize a 3D ink-jet printing approach with multiple print heads having fluids of differing refractive index, and we will use this machine to ...

The primary objective of this SBIR is to investigate a novel OMIR (OMnidirectional InfraRed) imaging sensor concept, which provides a low-cost solution to obtain video rate 360-degree IR images for situation awareness for the space/aerial and groundvehicles. In our Phase I effort, we have successfully demonstrated the feasibility of the OMIR concept. Specifically, our accomplishments include: (a ...

Piezoelectric actuators and motors promise to deliver useful work at power densities and order of magnitude greater than that of their electromagnetic counterparts. The circuit concept developed is for a resonant, regenerative switching piezomotor driveamplifier that would efficiently transfer electrical energy that could be coupled into mechanical work through a piezoelectric actuator. The motor/ ...

The occurrence of causative agents such as Cryptosporidium parvum and other pathogens in water supplies presents a critical issue. Transmitted through water and animals, these organisms provide a reservoir of infection, which results in the excretion of the environmentally stable cysts or oocysts that are impervious to inactivation by many drinking water disinfectants. Cryptosporidium infections a ...

Cryptosporidium, originating from contamination of public drinking water supplies, ponds, rivers, or swimming pools, have cause large-scale and deadly outbreaks, which became a major cause of waterborne infectious diseases. Since 1991, the percent of outbreaks attributable to Cryptosporidium has doubled, and in the 1993-1994 period, 17 percent of all outbreaks were caused by Cryptosporidium. In 19 ...
