Abstract: A system and method for discovering similar time sequences in a database of time sequences includes a computer-implemented program which first breaks each sequence into small windows. The windows from the first sequence are compared to selected windows from the second sequence to determine which windows are similar. Pairs of similar windows are then stitched together when certain stitching constraints are met to establish pairs of similar subsequences. Likewise, pairs of similar subsequences are stitched together, and the lengths of the stitched subsequences are then compared to the overall length of the time sequences to determine whether the time sequences meet a similarity criteria.

Abstract: A memory controller parity system that detects both even and odd bit errors in memory addresses and global errors in memory data. The parity system detects errors in any memory system employing an address bus or data allocation map. It is effective for applications requiring random memory accesses as well as in blocked-data accesses such as in controller buffer memories for servicing disk file systems and tape storage systems. The controller stores data in memory together with a single appended global parity bit representing (n-1) bits from an n-bit address, thereby detecting both even and odd fixed errors over time. A p-bit identification register can be added to the controller to facilitate detection over time of global data errors arising from data allocation map errors during the data storage period. The single-bit parity scheme is compatible with existing single-bit parity memory systems.

The above arrangement facilitates simpler expansion of the library and assures its operability even though one or two picker modules should fail.

Abstract: A database management system determines, in a single pass over an unordered database, the quantile information. The system sequentially compares each tuple in the data set to a test value, and then selectively inserts the tuple in a test set having a cardinality less than the cardinality of the data set based upon the comparison. The system next uses the quantile information to estimate the number of tuples in the database which satisfy a user-defined predicate to generate an efficient query plan.

Abstract: A retainer includes a resilient split band with a transition region and a loading region between its top and bottom edges. The loading region of the split band is provided with a plurality of loading domes which extend inwardly and a plurality of tabs which are located in the transition region of the split band adjacent its top edge. Upon assembly, the inner annular edge of the disk is located in the transition region of the split band with the top surface of the disk engaging the bottoms of the tabs. Downward movement of the split band on a spindle hub causes the loading domes to engage a cylindrical hub and cone the split band with its bottom edge located inwardly from its top edge. Pushing downwardly on the tabs causes the disk and the retainer to be forced downwardly on the spindle hub until the bottom edge of the split band engages a hub flange within a recess adjacent the hub.

Abstract: A cartridge magazine with interfaces to automatic cartridge feeder devices. On one side, the magazine has an open interface that provides unencumbered access by a robotic picker that accesses cartridges for a library. The magazine is accessible on another side by a transport mechanism of an automatic cartridge feeder (ACF). The transport carries a cartridge from the magazine to a drive unit where the data stored on the cartridge is read or new data is written. The interface to the ACF includes a handle member for placing the magazine into the feeder. The magazine is mounted by loading it into the feeder and pushing the handle inward allowing a plunger on the ACF to engage a groove on the handle member that locks the magazine into place. Locking the magazine in place activates a sensor, thereby enabling the operation of the feeder. The interface securely engages the ACF so that the magazine cannot be accidentally dislodged from it.
