Briefly, the present invention relates to an information dispersal sytem in which original data to be stored is separated into a number of data “slices” in such a manner that the data in each subset is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other data subsets. These data subsets are stored on separate storage devices as a way of increasing privacy and security. In accordance with an important aspect of the invention, a metadata management system stores and indexes user files across all of the storage nodes. A number of applications run on the servers supporting these storage nodes and are responsible for controlling the metadata. Metadata is the information about the data, the data slices or data subsets and the way in which these data subsets are dispersed among different storage nodes running over the network. As used herein, metadata includes data source names, their size, last modification date, authentication information etc. This information is required to keep track of dispersed data subsets among all the nodes in the system. Every time new data subsets are stored and old ones are removed from the storage nodes, the metadata is updated. In accordance with an important aspect of the invention, the metadata management system stores metadata for dispersed data where: The dispersed data is in several pieces. The metadata is in a separate dataspace from the dispersed data. Accordingly, the metadata management system is able to manage the metadata in a manner that is computationally efficient relative to known systems in order to enable broad use of the invention using the types of computers generally used by businesses, consumers and other organizations currently.

A replicated decentralized storage system comprises a plurality of servers that locally store disk images for locally running virtual machines as well as disk images, for failover purposes, for remotely running virtual machines. To ensure that disk images stored for failover purposes are properly replicated upon an update of the disk image on the server running the virtual machine, a hash of a unique value known only to the server running the virtual machine is used to verify the origin of update operations that have been transmitted by the server to the other servers storing replications of the disk image for failover purposes. If verified, the update operations are added to such failover disk images. To enable the replicated decentralized system to recover from a failure of the primary server, the master secret is subdivided into parts and distributed to other servers in the cluster. Upon a failure of the primary server, a secondary server receives a threshold number of the parts and is able to recreate the master secret and failover virtual machines that were running in the failed primary server.

The internal and external plumbing also allows for the system to be completely bypassed in the event of power failure or the introduction of undesirable contaminants into the grey water source stream.

Dry powder inhalers with integrated active energy patient assist dispersal systems are configured with control systems which provide adjustable energy output responsive to the user's inspiratory capabilities and / or the flowability of the dry powder drug being administered. The multi-dose dry drug package includes a piezoelectric polymer substrate (such as PVDF) which flexes to deform and provide mechanical oscillation in a selected region of the package corresponding to the dry powder drug dose in the exit flow path and is thus actively dispersed into the exit flow path of the inhaler during the user's inspiratory activity. Control systems employ fuzzy logic models of the flowability of particular drug formulations (also being able to compensate or allow for the particular type of excipient used) and / or adjust for the real-time measured inspiratory efforts of the user. Manufacturing process control systems can adjust certain parameters in response to a fuzzy logic model of the flowability of the dry powder and other conditions associated with the dry powder drug being produced and / or dispensed.

A billing process is disclosed for a information dispersal system or digital data storage system. In one embodiment of the invention, the original data to be stored is separated into a number of data “slices” or shares in such a manner that the data in each subset is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other data subsets. These data subsets are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being stored or removed from a grid of distributed storage locations, a set of metadata tables are created, separate from the dispersed file share storage, to maintain information about the original data size of each block, file or set of file shares dispersed on the grid. The original data size information in these separate metadata tables is used to determine usage information based upon the original file size even though the file has been dispersed onto a storage grid that contains file slices who size may not relate to the original file size and the file slices may have been compressed by the system in order to reduce storage space or improve transmission time. As such, the billing process is able to enable a broad range of commercial billing options for billing for commercial data services on an information dispersal grid.

Finite element methods are unsuitable for a dispersed system. Particle methods suitable for a dispersed system are limited in the particle shapes only a sphere that requires many particles to model a complicated shape especially in 3D. Proposed procedures for a particle method are roughly as follows. 1): Judging the existence of the contact between particles as that between mathematically-smooth closed surfaces representing particle shape and size. 2): Assuming an imaginary contact point and an imaginary contact plane the same as when both closed surfaces are reduced with the same scale to touch at one point. 3): Calculating imaginary contact area and imaginary contact stiffness etc. using the above point and plane. Based on these procedures, particle shapes are not limited but smooth. Therefore, a more complicated shaped problem in a dispersed system can be analyzed with less number of particles. Additionally, combined use with finite elements is capable.
