A method, apparatus, and program product are provided for creating an Encoded Matrix Index for a column in a database table. An element of the column for all rows in the database table is compared to a corresponding reference value in a reference data structure, and in response to at least one value for the element of the column not matching the reference value, indicating a variation in a variation data structure and creating a value data structure. Queries executed using the Encoded Matrix Index include terms associated with a sub-column defined in a column of a database table. The variation data structure is accessed to determine whether any variation exists between rows belonging to a sub-column of the database table. If no variation exists, a value is accessed from the reference data structure; otherwise, a value for each row of the sub-column is accessed from a value data structure.

To support a forward error correction scheme, in which a code of the forward error correction scheme is employed at a transmitting end for encoding data for a transmission to a receiving end, the transmitting end compresses at least one binary parity check matrix associated to the employed code of the forward error correction scheme. The transmitting end then provides the compressed binary parity check matrix for a transmission to the receiving end. The receiving end receives the compressed binary parity check matrix and decompresses it for use in a forward error correction based on encoded data received from the transmitting end.

A “forward” delta data management technique uses a “sparse” index associated with a delta file to achieve both delta management efficiency and to eliminate read latency while accessing history data. The invention may be implemented advantageously in a data management system that provides real-time data services to data sources associated with a set of application host servers. To facilitate a given data service, a host driver embedded in an application server connects an application and its data to a cluster. The host driver captures real-time data transactions, preferably in the form of an event journal that is provided to the data management system. In particular, the driver functions to translate traditional file / database / block I / O into a continuous, application-aware, output data stream. In an illustrative embodiment, a given application aware data stream is processed through a multi-stage data reduction process to produce a compact data representation from which an “any point-in-time” reconstruction of the original data can be made.

In a telecommunications network, information about events that occur at nodes (27) is sent to event-based management applications (31) in operations and maintenance servers (21). Event reports (23) comprising such event information are replaced or accompanied in data packets by event summaries (33). The summaries (33) can be used to route the data packets to the correct event-based management application (31) with less processing time and resources than if the event reports (23) are used for routeing, because information about the events can be obtained from the summaries (33) more easily than from the event reports (23). Routeing using the summaries (33) may be done in a fast path. Some event-based management applications can use the summaries (33) instead of the event reports (23), which can also save processing time and resources, and such event-based management applications may be performed in a fast path.

Embodiments of the present invention relate generally to reconstruction filtering. In particular, embodiments enable highly linear, highly programmable, and easily reconfigurable reconstruction filters. Further, embodiments provide substantial power consumption, area, and cost savings compared to conventional solutions. For example, embodiments use all-passive filtering and substantially reduce active elements compared to conventional solutions. As a result, significant reductions in required area, noise, and power consumption can be achieved. In addition, embodiments perform filtering solely in the current domain, thereby eliminating the non-linear voltage-to-current conversion used in conventional circuits and enabling highly linear filtering. Furthermore, embodiments are highly programmable and easily reconfigurable without the use of tunable capacitors. As such, embodiments are very suitable solutions for multi-band multi-mode wireless transmitters.

A wireless network device, such as a printer, to enter an infrastructure-type user wireless LAN as a station, has an additional access point function. A printer having an ESS-ID ‘MM’ as an initial setting is connected with a user wireless LAN, which includes an access point and a personal computer and uses a common ESS-ID ‘XX’. In this case, the procedure changes the ESS-ID set in the personal computer to ‘MM’ to establish an infrastructure-type communication with the printer. This arrangement enables the ESS-ID set in the printer to be changed to the common ESS-ID ‘XX’ for the user wireless LAN without varying the ESS-ID set in the access point. The technique of the invention ensures easy connection of any device without sufficient input interfaces to the wireless LAN.
