In this proposal, AlphaSense, Inc. (AI) and the Carnegie Mellon University (CMU) detail the development of RF front end based on MEMS components for miniaturized digital EVA radio. Key innovations of our approach include: a) the use of a novel parallel receiver front end architecture based on MEMS components, b) a novel design of a high Q mixer-filter for RF mixing and IF filtering, and c) the imp ...

Many large-scale numerical simulations can be broken down into common mathematical routines. While the applications may differ, the need to perform functions such as matrix solves, Fourier transforms, or eigenvalue analysis routinely arise. Consequently, targeting fast, efficient implementations of these methods will benefit a large number of applications. Graphics Processing Units (GPUs) are e ...

We propose an improved cathode based on our novel theory of the role of scandium oxide in enhancing emission in tungsten impregnate cathodes. Recent results have demonstrated the efficacy of nano-particle scandium oxide, but a detailed theory on mechanism has been lacking. Our theory explains published data and point to an optimized cathode which we here propose to build and test at our facility ...

Horizon Performance designed a Behavior Tracking Software System to collect crew member behavior throughout a mission, giving NASA the capability to monitor behavioral patterns that may identify if crews are at increased risk related to interpersonal or psychosocial problems. Building upon the alpha version of the software developed as a part of the Phase I SBIR, the proposed software will allow c ...

Bennett Aerospace and Team Partners propose to develop a small, lightweight, and very power-efficient mobile radio for use on the Lunar surface. Our Team will achieve a design that meets NASA size and mass requirements while reducing power consumption by more than 90%. We will accomplish this through innovative approaches in power management and RF front end design.

Innovative Technology Applications Company and Drs. P. Morris and K. Brentner will make improvements in noise prediction and measurement methods for subsonic and supersonic vehicles. Possible areas of application for the finished product include aerodynamic noise from fans, jets, turbomachinery, engine cores, propfans, propellers, and airframe components. The proposed Phase I work will result in ...

Spacecraft need accurate position and velocity estimates in order to control their orbits. Some missions require more accurate estimates than others, but nearly all missions need some type of orbit determination. IST-Rolla seeks to provide highly accurate algorithms that do not overpower the spacecraft's computer. Many new, powerful algorithms exist such as the particle filter and the unscented ...

State of the art Radiation Hardened by Design (RHBD) techniques do not account for wide temperature variations in BiCMOS process. Silicon-Germanium BiCMOS process offer inherent advantages for operation in radiation environments where single event transient and total iodization dose effects on the circuit are important. Recent access to libraries of wide temperature and RHBD BiCMOS designs provid ...

Ultrastable, narrow linewidth, high reliability MOPA sources are needed for high performance LIDARs in NASA for, wind speed measurement, surface topography and earth and planetary atmosphere composition measurements. Princeton Optronics is developing a MOPA laser source for these applications. Phase I experiments concluded that the optimum approach will use a DPSS microchip laser with the SOA. Th ...

Recovery of water from brine is critically important for future manned space exploration. Resupply of water is prohibitively costly for such extended missions. Water reclamation processes typically recover 90-95% of the water present in wastewater formed by combining urine, hygiene water, and humidity condensate with the remaining concentrated in brine. This concentrated brine contains a signif ...
