A composite oxygen ion transport element that has a layered structure formed by a dense layer to transport oxygen ions and electrons and a porous support layer to provide mechanical support. The dense layer can be formed of a mixture of a mixed conductor, an ionic conductor, and a metal. The porous support layer can be fabricated from an oxide dispersion strengthened metal, a metal-reinforced intermetallic alloy, a boron-doped Mo5Si3-based intermetallic alloy or combinations thereof. The support layer can be provided with a network of non-interconnected pores and each of said pores communicates between opposite surfaces of said support layer. Such a support layer can be advantageously employed to reduce diffusion resistance in any type of element, including those using a different material makeup than that outlined above.

For resonance image data of an imaged subject, a method that first detects and estimates the dominant motions of k-space data (i.e., the motion vectors) and then constructs a graphical model for each estimated motion vector. The segments of the k-space that are determined to be corrupted by motion are restored by minimizing the energy associated with the corresponding graphical model. Consequently, the MR image of the imaged subject becomes free of motion artifacts.

A modular charging system for series-connected battery packs is disclosed. An individual isolated charging module is connected across each cell in the pack. A battery cell and its corresponding charging module form a battery module assembly, a plurality of which are connected in series to form a complete battery pack of desired characteristics. A common input power input bus is shared between all charging modules and is connected in a daisy-chain fashion to a single input power source. A common isolated communications bus, which may be isolated CAN bus, is similarly shared and daisy-chained between all modules, connecting them to a monitoring processor.

A metalized circuit suitable for application as a radio frequency antenna is produced by forming an antenna coil pattern on a flexible substrate. The antenna coil pattern is formed using a conductive ink which is patterned on the substrate. The conductive ink is cured and an electrical-short layer is formed across the coils of the conductive ink pattern. An insulating layer is formed over top of the electrical-short layer, a metal layer electroplated on top of the conductive layer, and then the electrical-short layer is removed. The use of the electrical-short layer during the electroplating allows for the voltage at the different points on the conductive ink layer to be relatively similar, so that a uniform electroplate layer is formed on top of the conductive ink layer. This results in a better quality radio frequency antenna at a reduced cost.

Mirroring data to provide a virtual storage area network using policing protocols and mirror engines without a physical shared storage node. The mirror engines are found at each server computer in the network in order to mirror the data between mass storage devices of the servers as the servers receive and execute write operations, which results in each mass storage device containing the same stored data. The policing protocols prevent data corruption by not allowing more than one server at a time write to a file of data. If one server experiences failure and is incapable of providing access to network data, the other server or servers can service all read requests, since all network data is accessible by all servers. Unlike conventional storage area networks, there is no physical shared storage node and, accordingly, the costs of obtaining and operating the virtual storage area network are relatively small.
