摘要： A method and system for providing a scalable storage scheme for native hierarchically structured data of relational tables, includes a base table with indicator columns with information pertaining to hierarchically structured data of a document, data tables for storing the hierarchically structured data corresponding to the indicator columns, and node identifier indexes corresponding to the data tables for mapping between the indicator columns and the hierarchically structured data in the data tables. In an embodiment, actual data for each hierarchically structured data (such as XML) column is stored in a separate data table, and each data table has a separate node identifier index. The node identifier index is searched with a key containing the document identifier and a logical node identifier is used, and a record identifier of a record in the data table containing the node assigned the logical node identifier is retrieved.

摘要： A system and method is provided for providing integrated over-current protection in a switching power supply. In one embodiment, a switching power supply could comprise a gate drive circuit operative to receive a pulse-width modulated (PWM) signal and to drive at least one power field effect transistor (FET) between alternating activated and deactivated states based on a pulse-width of the PWM signal. The switching power supply could also comprise a current sense circuit operative to measure a current associated with the at least one power FET during the activated state. The switching power supply could also comprise a first over-current protection circuit providing a first adjustment to the PWM signal in response to the current being substantially between a first threshold and a second threshold. The second threshold could be greater than the first threshold. The switching power supply could further comprise a second over-current protection circuit providing a second adjustment to the PWM signal in response to the current being substantially greater than the second threshold.

摘要： The present system indexes a plurality of entries in a database that contains a database table having a base index. As a recent row is inserted in the database table, an index increment is generated based on the inserted row. Preferably, the index increment is smaller in size than the base index because it is recently generated. The smaller size of the index increment facilitates the management of the index increment. An index entry associated with the inserted row is added to the index increment, and the index increment is merged with the base index.
摘要翻译：本系统对包含具有基本索引的数据库表的数据库中的多个条目进行索引。由于最近一行插入到数据库表中，所以根据插入的行生成索引增量。优选地，索引增量的大小比基本索引更小，因为它最近被生成。索引增量的较小尺寸有助于指数增量的管理。与插入行相关联的索引条目被添加到索引增量中，索引增量与基本索引合并。

摘要： An overprint lacquer comprising a solvent, a resin, a plasticizer, and a gelling agent. The gelling agent is hydroxypropylcellulose acetate. The coatings of this gel-containing lacquer show improved adhesive characteristics and improved durability when compared with conventional overprint lacquers that have higher nitrocellulose content. Also, the viscosity of the lacquer is more readily controllable due to the presence of the gelling agent.

摘要： A partial index availability system places, in a restricted state, all pages in the index associated with a structure modification, when an error occurs in processing a log of the said structure modification. This maintains traversability of the rest of the index that is not in restricted state. The system locates and marks a left sentinel and a right sentinel associated with a non-leaf page that is in a restricted state preventing an undo of a transaction. The sentinels prevent a transaction from accessing an uncommitted change associated with the non-leaf page. After a recovery procedure is run the entire index is made available. During the period between the placement of the index pages in LPL or rebuild pending to the time of final removal of these pages from their restrictive states as a result of a recovery procedure being run, the users are given access to the non-restricted portion of the index.
