Two-dimensional data storage system
A method providing a level of indirection that abstracts the details of physical data storage, requiring neither indexing nor contiguity of data elements in physical storage for efficient data access. Tables are organized in a diagonal pattern (with a natural implementation in electronic spreadsheets), where the region occupied by each table is expandable and shrinkable. A novel query processing mechanism applies successive expressions in a query to progressively smaller arrays of references to a table's records. A novel method for implementing join operations avoids data replication, where the table derived from the join contains a matrix of references to values in the original tables. The derived table can subsequently be used to update the original tables via references, where this capability can be utilized in a user interface supporting atomic data entry transactions, where users may edit the derived table, and the corresponding original tables are atomically updated.

More efficient search algorithm (MESA) using alpha omega search strategy
A more efficient search algorithm introduces a variety of new tools and strategies to more efficiently search and retrieve desired records from an electronic database. Among these are a strategy that utilizes the first and last positional characters, or phonemes, to exploit the fact that often last positional character is nearly as important as a first positional character in distinguishing database records from one another. In addition, virtual search parameters, that are not a portion of the database records, can also be utilized in distinguishing database records, such as by identifying a number of characters in a search field for a requested database record as a way of distinguishing that record from all others with a different number of characters. The invention finds potential application in any database search application, but is particularly useful in delivering directory assistance services.

Mobile device with an obfuscated mobile device user identity
A mobile device identifier (such as an MSISDN) that typically accompanies a mobile device request is replaced with an “enriched” identifier that exposes the mobile device user's home operator but obfuscates the mobile device's (and, thus, the device user's) identity. In one embodiment, the identifier comprises a first part, and a second part. The first part comprises a data string that identifies (either directly or through a database lookup) the mobile device user's home operator. The second part, however, is an opaque data string, such as a one-time-use unique identifier (UID) or a value that is otherwise derived as a function of the MSISDN (or the like). The opaque data string encodes the mobile device's identity in a manner that preferably can be recovered only by the user's home operator (or an entity authorized thereby). When the mobile device user roams into a foreign network, that network receives the enriched identifier in lieu of an MSISDN. The foreign network uses the first part to identify the mobile device user's home network, e.g., to determine whether to permit the requested access (or to provide some other value-added service). The foreign network, however, cannot decode the second part; thus, the mobile device's identity (as well as the identity of the mobile device user) remains obscured. This ensures that the user's privacy is maintained, while preventing third parties from building a profile of the device based on the requests that include the MSISDN or similar identifier.

Subscriber data (TD2) is subsequently transmitted from the second to the first telecommunication device, in accordance with the information from the first device. It is also conceivable that device information (GI2) can be transmitted from the second to the first telecommunications device, in accordance with which subscriber data (TD1) can finally be transmitted from the first to the second telecommunications device. The use of device information that is exchanged between two telecommunications devices and indicates which subscriber data should be transmitted to the respective other telecommunication device thus permits a reduction in the data flow between two telecommunications devices with respect to subscriber data, as only the desired subscriber data is transmitted.

Variable bit rate video CODEC using adaptive tracking for video conferencing
The present invention is directed to a video communication system capable of providing adaptive compression of video image data. In particular, data regarding the range of possible motions and the respective probabilities of such motion within a scene are collected, and a compression algorithm appropriate to motions having high associated probabilities selected.

Monolithic folded F-P cavity and semiconductor laser using the same
This invention relates to a monolithic folded F-P cavity used for semiconductor laser, which is composed of a monolithic optical element.
