Two approaches are proposed to attack the problems of fixturing process. First, a novel hardware holding system, Dexterous Vise, is proposed. Functionally, a single Dexterous Vise is capable of revealing four faces of the clamped workpiece to the cutting tool without re-fixturing, which actually increases one degree of freedom to the machine tool. A pair of Dexterous Vises, the "Dual-Vise", ena ...

ACX proposes an innovative new process for the manufacture of smart structures using a High Velocity Oxy-Fuel (HVOF) thermal spray process. This simple, multi-step process will be capable of depositing electroded piezoceramic coatings. The coatings will be poled while still hot, reducing poling times and voltages while increasing poling efficiency. Process times will be extremely short. The pr ...

Current designs for rural safety mailboxes combined with a lack of safety design regulations, produce a hazardous situation for errant rural motorists. When impacted, rural mailboxes have been shown to dislodge from their posts and penetrate automobile windshields. In addition, rural residents are faced with a constant maintenance problem from winter snow plows, vandals, and vehicle impacts. A ...

We propose a radically innovative approach to the problem of multiple access communication which promises to revolutionize the modern communication industry by dramatically increasing network throughput. Our approach is based upon two major novel components: (i) hybrid time-frequency allication of communication channel resources, and(ii) non-orthogonal, i.e., overlaping, multiplexed signals. Toge ...

In order to realize the full potential of cryogenic power converters, it is vital to develop the technology for cryogenic capacitors and inductors, in order to be combined with the switching semiconductors. Capacitors with high dielectric constant and high voltage withstand at cryogenic temperatures with low weight and volume lie on the critical path. The proposed work focuses on innovative tech ...

To Operate effectively, PEM small fuel cells stacks need a chemical hydride hydrogen generator. The chemical hydride digital reactor suggested in the proposed program will provide about 2.5 kWH of energy in a5 pound package.--almost three times the energy density of a BA5590 battery. Studies and experiments will be conducted with spe ...

Proposed is the technical development and design of the electronics and cooling systems for a 1 megawatt cryogenically cooled inverter suitable for use in a wide range of applications, including Uninterruptable Power Suplies (UPS) and motors in the +1000 HP range. The proposed work will provide a logical progression to the development that has already been done by American Superconductor Corp. I ...

Semi-automated analysis of citrus grove data from remotely-sensed devices can reduce groundsurveying for appraisal, crop recording, yield analysis, and grove management. Although theygenerally start with the same aerial infrared imagery for their data collection, grove managers andindependent appraisers each have their own independent requirements for data analysis. By making theanalysis of this ...

This project is designed to investigate an innovative remotely delivered needle-less controlled release implant to provide antimicrobial (ceftiofur) therapy to calves with bovine respiratory disease complex. Bovine respiratory disease complex is the most economically important (an economic impact of $624 million in 1992) infectious disease of calves in North American feedlots. Although antimicro ...

The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...
