A computer filing system includes a data access and allocation mechanism including a directory and a plurality of indexed data files or hash tables. The directory is preferably a radix tree including directory entries which contain pointers to respective ones of the hash tables. Using a plurality of hash tables avoids the whole database ever having to be re-hashed all at once. If a hash table exceeds a preset maximum size as data is added, it is replaced by two hash tables and the directory is updated to include two separate directory entries each containing a pointer to one of the new hash tables. The directory is locally extensible such that new levels are added to the directory only where necessary to distinguish between the hash tables. Local extensibility prevents unnecessary expansion of the size of the directory while also allowing the size of the hash tables to be controlled. This allows optimisation of the data access mechanism such that an optimal combination of directory-look-up and hashing processes is used. Additionally, if the number of keys mapped to an indexed data file is less than a threshold number (corresponding to the number of entries which can be held in a reasonable index), the index for the data file is built with a one-to-one relationship between keys and index entries such that each index entry identifies a data block holding data for only one key. This avoids the overhead of the collision detection of hashing when it ceases to be useful.

A mobile device case system includes a first case system component usable to at least partially enclose a mobile device. A second case system component is attachable to the first case component (e.g., mechanically and/or electronically) to provide additional features and functionality such as, for example, an expansion battery and/or an external display. The second case system component can be replaced with other system components to, for example, change the display, replace the battery, or provide a decorative cover for the external surface of the case system.

The vortex chamber (1) has a curved wall (12), a tangential inlet port (3) and an axial exit port (2). The radius R of the vortex chamber (1) decreases with angular extend θ. The reduction in effective cross-sectional area of the vortex chamber accelerates the gas flow between the inlet (3) and the outlet (2) to reduce deposition of the medicament.

An optical disk comprises a disk substrate having a hub and an annular optical metallicized data region extending radially outward from the hub. The optical disk further comprises a radio frequency identification (RFID) transponder affixed to the disk substrate, e.g., within the non-data containing hub region. The optical disk further comprises at least one linear antenna element coupled to the transponder, e.g., via pole lead(s), and extending within the data region. The antenna element(s) can be applied to the disk substrate as a patterned antenna layer over a metallicized data region, and can be electrically isolated from the data region. A method and system of identifying an optical disk is provided. A radio frequency (RF) signal can be transmitted to the optical disk at a range of at least five feet, and preferably at a range of at least ten feet. An RF signal with an identification code (e.g., a unique number) can be received from the optical disk in response to the transmitted RF signal. The activating RF signal can be transmitted by, and the identification RF signal can be received by, e.g., a handheld RF reader or an RF reader that is affixed to a building. The identification code can then be processed for many purposes, such as identifying the optical disk as a non-counterfeited optical disk, calculating a royalty, or tracking the location of the optical disk.

A system and method are disclosed for utilizing compression in database caches to facilitate access to database information. In contrast with applying compression to the database that is stored on disk, the present invention achieves performance advantages by using compression within the main memory database cache used by a database management system to manage data transfers to and from a physical database file stored on a storage system or stored on a networked attached device or node. The disclosed system and method thereby provide a significant technical advantage by increasing the effective database cache size. And this effective increase in database cache size can greatly enhance the operations-per-second capability of a database management system by reducing unnecessary disk or network accesses thereby reducing data access times.

An electronic image stabilizer in a digital camera compensates for camera motion-induced blurriness by segmenting exposure times into multiple shorter exposure times and summing the individual pixels from successive frames after applying an appropriate motion correction. Motion is detected by computing the correlation function between successive images, and compensation is applied by maximizing the correlation function. This avoids the need for mechanical stabilization devices in order to detect or correct the motion as is done in prior art. This method further enables the detection of moving objects in a still background, and correction of blurriness images due to such motion.
