  • MANAGING DATA RECORDS
    Publication number: 20180089246
    Abstract: Data records may be managed in a relational database by monitoring, a record length for a first data record in a page of memory, an amount of free space in the page, and a page length. In response to receiving an operator command to replace the first data record with a second data record, a database management system may determine whether an estimated record length of a compressed second data record is outside of the amount of free space in the page. In response to determining the estimated record length of a compressed second data record is outside of the amount of free space in the page, the database management system may determine whether an estimated length of a compressed page is outside of the page length. In response to determining the estimated length of a compressed page is within the page length, the page may be compressed.

  • INDEX B-TREE MAINTENANCE FOR LINEAR SEQUENTIAL INSERTION
    Publication number: 20180067974
    Abstract: An approach for index B-tree page creation associated with linear sequential insertions in database management systems (DBMS). A linear pre-splitter receives a current index leaf page for linear sequential insertion. The linear pre-splitter asynchronously creates index leaf pages where the current index leaf page is in a predetermined position at least one page away from a last index leaf page. The linear pre-splitter updates index leaf page position identifiers associated with the index leaf pages where the index leaf page position identifiers link the index leaf pages and the last index leaf page and the linear pre-splitter inserts index leaf page identifiers and index key metadata associated with each of the index leaf pages into index non-leaf pages.

  • Dual torsion springs flapper valve closure mechanism
    Patent number: 9909389
    Abstract: A flapper valve includes a body having first and second end, and a flapper pivotably coupled to the body and movable between a closed position, where the flapper prevents fluid flow through the body, and an open position, where fluid flow is allowed through the body. A first torsion spring is coupled to the body at the second end and provides a spring arm that engages and urges the flapper to the closed position. A support beam is coupled to the body and includes an axial extension that extends axially past the second end. A closure beam having a first beam end is pivotably coupled to the axial extension and a second beam end is engageable with the flapper. A second torsion spring is coupled to the axial extension and engageable with the closure beam to urge the closure beam into engagement with the flapper.

  • ALLOCATING FREE SPACE IN A DATABASE
    Publication number: 20170322957
    Abstract: Allocating free space in a database table. Statistics associated with records in a database are received, including an average record byte size for records stored in the database table. A primary free space byte size for record updates is determined, including comparing a preliminary free space byte size to the average record byte size and a byte size of a record subjected to a database operation. Based on the primary free space byte size, free space at the page level of the database table is allocated.

  • COLOR IMAGE PROCESSING SYSTEM AND COLOR IMAGE PROCESSING METHOD
    Publication number: 20170169547
    Abstract: A color image processing system includes an image capture module, an image digitizing module, an optimizing ratio calculation module and an image processing module. The image capture module captures an original color image. The image digitizing module digitizes the original color image to obtain N pixels in ascending order according to value of RGB of the pixel. The optimizing ratio calculation module calculates an optimizing ratio H. The image processing module multiplies original value of RGB of the pixel before the ((N?N*H)/2)th pixel by 1/H to obtain new value of RGB of the pixel before the ((N?N*H)/2)th pixel and multiplies original value of RGB of the pixel after the ((N+N*H)/2?1)th pixel by H to obtain new value of RGB of the pixel after the ((N+N*H)/2?1)th pixel. A color image processing method is also provided.
