An encrypted file storage solution consists of a cluster of processing nodes, external data storage, and a software agent (the “File System Watcher”), which is installed on the application servers. Cluster sizes of one node up to many hundreds of nodes are possible. There are also remote “Key Servers” which provide various services to one or more clusters. The preceding describes a preferred embodiment, though in some cases it may be desirable to “collapse” some of the functionality into a smaller number of hardware devices, typically trading off cost versus security and fault-tolerance.

Described is a system for filtering, segmenting and recognizing objects. The system receives a three-dimensional (3D) point cloud having a plurality of data points in 3D space and down-samples the 3D point cloud to generate a down-sampled 3D point cloud with reduced data points in the 3D space. A ground plane is then identified and removed, leaving above-ground data points in the down-sampled 3D point cloud. The above-ground data points are clustered to generate a plurality of 3D blobs, each of the 3D blobs having a cluster size. The 3D blobs are filtered based on cluster size to generate a set of 3D candidate blobs. Features are extracted from each 3D candidate blob. Finally, at least one of the 3D candidate blobs is classified as a pre-defined object class based on the extracted features.

The invention relates to a power balancing-based non-uniform clustering method for a cluster wireless sensor network, relating to wireless communication technologies. The method comprises the steps of dividing a wireless sensor network monitoring region with uniformly distributed nodes into a non-uniform a ring, determining the positions of cluster head nodes according to an equivalent distance method, ensuring a reliability link index deltap of end-to-end communication between the cluster head nodes to cluster nodes, and setting up an energy consumption solving equation. An optimal ring radius vector is obtained by optimizing parameters of the energy consumption solving equation of the cluster head nodes with a steepest gradient descent algorithm based on the idea of 'power-balancing'. The cluster size is finally obtained by adjusting the positions and the transmission power of the cluster head nodes in accordance with the optimal ring radius vector, so as to balance energy consumption among the cluster head nodes and prolong the network life cycle. The method remarkably prolongs the network life cycle, improves the efficiency of the routing protocol and the media control protocol, and provides a support basis for time synchronization, data integration and target positioning technologies.

A cluster system is treated as a set of resource groups, each resource group including an highly available application and the resources upon which it depends. A resource group may have between 2 and M data processing systems, where M is small relative to the cluster size N of the total cluster. Configuration and status information for the resource group is fully replicated only on those data processing systems which are members of the resource group. A configuration object / database record for the resource group has an associated owner list identifying the data processing systems which are members of the resource group and which may therefore manage the application. A data processing system may belong to more than one resource group, however, and configuration and status information for the data processing system is replicated to each data processing system which could be affected by failure of the subject data processing system-that is, any data processing system which belongs to at least one resource group also containing the subject data processing system. The partial replication scheme of the present invention allows resource groups to run in parallel, reduces the cost of data replication and access, is highly scalable and applicable to very large clusters, and provides better performance after a catastrophe such as a network partition.

A Hard Disk Drive (HDD) is provided two FATs and two cluster sizes, a regular cluster and a “Supercluster”. In one example, each Supercluster is the size of four regular clusters. A second Supercluster FAT is added (FAT2) which works in a similar manner to the original FAT (hereinafter FAT1), but instead points to the next Supercluster in the chain. Since there are far fewer Superclusters than clusters, the Supercluster FAT (FAT2) can be stored in a cache memory. When data is streamed to and from the hard drive, it can be streamed to Superclusters and no seeks on the HDD to a FAT are required, as the FAT2 is cached in memory. Access time to and from the hard drive is decreased. The original cluster configuration is still supported. During lulls in system operation, the FAT2 data may be written to the drive and moreover, FAT1 data created and “flushed” to the hard drive. Thus, if the HDD is read by a standard computer system, it will recognize the regular clusters from the FAT1 table in a transparent manner (and ignore the FAT2 table).
