A method of making a metal capacitor includes the following steps. A dielectric layer having a metal interconnection and a capacitor electrode is provided. Then, a treatment is performed to increase the dielectric constant of the dielectric layer surrounding the capacitor electrode. The treatment can be UV radiation, a plasma treatment or an ion implantation. Accordingly, the metal capacitor will have a higher capacitance and RC delay between the metal interconnection and the dielectric layer can be prevented.

A method for locating application records in an interactive-service database is described. The method features steps for creating multiple search tables which represent subsets of the database to be interrogated; for example the applications of an interactive service. In accord with the method, steps are provided for arranging the tables with keyword, record locators, indexed to record identifiers. Additionally, the method includes steps for providing each table with a unique coding and steps for generating table codes at the user reception system in response to a query for a database record entered with a variety of search strategies; as for example, character string searching approximating the record sought, alphabetized record searching, subject matter category searching and personalized record searching, among others. Further, the method includes steps for comparing the table code generated with available table codes for the database to select a table suited for the query. Thereafter, the appropriate table is presented at the reception system so the table keywords can be reviewed and a desired record selected and presented.

A content-aware application switch and methods thereof intelligently switch client packets to one server among a group of servers in a server farm. The switch uses Layer 7 or application content parsed from a packet to help select the server and to schedule the transmitting of the packet to the server. This enables refined load-balancing and Quality-of-Service control tailored to the application being switched. In another aspect of the invention, a slow-start server selection method assigned an initially boosted server load metric to a server newly added to the group of servers under load balancing. This alleviates the problem of the new server being swamped initially due to a very low load metric compared to that of others. In yet another aspect of the invention, a switching method dependent on Layer 7 content avoids delayed binding in a new TCP session. Layer 7 content is not available during the initial handshaking phase of a new TCP session. The method uses the Layer 7 content from a previous session as an estimate to help select the server and uses a default priority to scheduling the transmitting of the handshaking packets. Updated Layer 7 content available after the handshaking phase is then used to reset the priority for the transmit schedule and becomes available for use in load balancing of the next TCP session.

The invention, electronic book security and copyright protection system, provides for secure distribution of electronic text and graphics to subscribers and secure storage. The method may be executed at a content provider's site, at an operations center, over a video distribution system or over a variety of alternative distribution systems, at a home subsystem, and at a billing and collection system. The content provider or operations center and / or other distribution points perform the functions of manipulation and secure storage of text data, security encryption and coding of text, cataloging of books, message center, and secure delivery functions. The home subsystem connects to a secure video distribution system or variety of alternative secure distribution systems, generates menus and stores text, and transacts through communicating mechanisms. A portable book-shaped viewer is used for secure viewing of the text. A billing system performs the transaction, management, authorization, collection and payments utilizing the telephone system or a variety of alternative communication systems using secure techniques.

A file system layout apportions an underlying physical volume into one or more virtual volumes (vvols) of a storage system. The underlying physical volume is an aggregate comprising one or more groups of disks, such as RAID groups, of the storage system. The aggregate has its own physical volume block number (pvbn) space and maintains metadata, such as block allocation structures, within that pvbn space. Each vvol has its own virtual volume block number (vvbn) space and maintains metadata, such as block allocation structures, within that vvbn space. Notably, the block allocation structures of a vvol are sized to the vvol, and not to the underlying aggregate, to thereby allow operations that manage data served by the storage system (e.g., snapshot operations) to efficiently work over the vvols. The file system layout extends the file system layout of a conventional write anywhere file layout system implementation, yet maintains performance properties of the conventional implementation.

A system and method for organization and analysis of complex and dynamically interactive time series is disclosed. One example comprises a processor based system for relational analysis of physiologic signals for providing early recognition of catastrophic and pathologic events such as pathophysiologic divergence. The processor is programmed to identify pathophysiologic divergence of at least one of first and second physiologic parameters in relationship to the other and to output an indication of the divergence. An object-based method of iterative relational processing waveform fragments in the time domain is described wherein each more complex waveform object inherits the characteristics of the waveform objects from which it is derived. The first physiologic parameter can be the amplitude and frequency of the variation in chest wall impedance or nasal pressure and the second parameter can be a measure or indication of the arterial oxygen saturation.
