A method and system for forming a data table in memory on an end user system. The data table forming a library index of storage locations to electronic digital content in memory. The method consists of retrieving an encrypted file from storage. The file has a beginning, an end and a trailer section located just prior to the end. The file is read from the end a predetermined distance to verify if an identifier is present. Reading and decrypting the trailer section from the file read. Determining if there are any updates in the trailer section. In the case there are no updates in the trailer section then decrypting the reference table containing one or more data table location indicators for data items with the first decrypting key. Next, decrypting one or data items with the first decrypting key. Populating the data table with data items at locations specified in the reference table.

A system encrypts a name of content stored in a node of a hierarchical structure. A content receiving node encrypts a name of a predetermined node among names of nodes included in a content name, such as by using a hash function, and transmits the encrypted content name to receive the stored content. A relay node receives the content name including the encrypted name of the node and decrypts the encrypted name of the node, such as by using a reference table. The relay node uses the decrypted node name to relay the content request to the content storage node. Since the content name is encrypted, content routing may be performed without disclosing information associated with a hierarchical structure in which the content is stored.

A system and method for data deduplication is presented. Data received from one or more computing systems is deduplicated, and the results of the deduplication process stored in a reference table. A representative subset of the reference table is shared among a plurality of systems that utilize the data deduplication repository. This representative subset of the reference table can be used by the computing systems to deduplicate data locally before it is sent to the repository for storage. Likewise, it can be used to allow deduplicated data to be returned from the repository to the computing systems. In some cases, the representative subset can be a proper subset wherein a portion of the referenced table is identified shared among the computing systems to reduce bandwidth requirements for reference-table synchronization.

To help ensure high data quality, data warehouses validate and clean, if needed incoming data tuples from external sources. In many situations, input tuples or portions of input tuples must match acceptable tuples in a reference table. For example, product name and description fields in a sales record from a distributor must match the pre-recorded name and description fields in a product reference relation. A disclosed system implements an efficient and accurate approximate or fuzzy match operation that can effectively clean an incoming tuple if it fails to match exactly with any of the multiple tuples in the reference relation. A disclosed similarity function that utilizes token substrings referred to as q-grams overcomes limitations of prior art similarity functions while efficiently performing a fuzzy match process.

A probe, connectable to a machine tool, having an electric generator (16), supplying an electric or electronic circuit (22) with electric power, and a driving element (28), capable of relative rotation with respect to the stator of the electric generator. The rotation axis of the driving element is preferably a symmetry axis of the probe itself. The driving element is not connected to any external energy source, and can be set in rotation simply by activating the rotary axis of the machine tool.Advantageously, the driving element of the present invention is not directly connected with any mobile element of the machine tool, but is either rotatably mounted on the probe itself, or fixed on the reference table of the machine tool. Importantly, the inventive probe requires no additional connections to the machine tool on which it is mounted, besides the connection to the rotary spindle, which can be realized with a conventional tool-holder with a standardised tapered shank. In this way the inventive probe is fully compatible with standard probes, and can be mounted and used with standard tool-holders, without any adaptation. The self-powering function of the probe can be activated simply by sending appropriate rotation instructions to the machine tools.

An auto-learned hierarchy algorithm that learns the hierarchical layout of a power monitoring system. Historical power data from each meter is received and placed into a data table. The main is assumed to be at the top of the hierarchy and is designated as the reference. A check matrix is developed indicating whether a possible connection exists between each meter pair combination. A correlation coefficient matrix (CCM) is calculated based on the data table, and entries in which no connection is possible are zeroed. The column for the reference meter from the CCM is copied to a correlation reference array (CRA), and the meter having the highest correlation with the reference meter in the CRA is marked as connected to the reference meter in a connection table. That meter's power is subtracted from the data table and the procedure is repeated until all meters have been analyzed.

An system for segmenting strings into component parts for use with a database management system. A reference table of string records are segmented into multiple substrings corresponding to database attributes. The substrings within an attribute are analyzed to provide a state model that assumes a beginning, a middle and an ending token topology for that attribute. A null token takes into account an empty attribute component and copying of states allows for erroneous token insertions and misordering. Once the model is created from the clean data, the process breaks or parses an input record into a sequence of tokens. The process then determines a most probable segmentation of the input record by comparing the tokens of the input record with a state models derived for attributes from the reference table.

One embodiment of the present invention provides a system that accesses a desired element during execution of a program. During operation, the system receives a reference to the desired element. The system determines if the reference is an internal reference to a location in a local package that is currently executing, or an external reference to a location in an external package. If the reference is an external reference, the system uses an index component of the reference to lookup an address for the desired element in a global reference table. Next, the system uses the address to access the desired element. Note that the address retrieved from the global reference table is larger than the reference, which allows the address to access a larger address space than is possible to access with the reference alone.
