Abstract: A scenting device for attachment to an air filter in a HVAC system. The scenting device comprises a sheet formed from a material that is substantially impervious to air. The sheet is cut so as to form at least one opening through which the air to be scented flows. The opening is preferably serpentine and defines a plurality of fingers in the sheet. A relatively thick layer of a high viscosity liquid, such as a gel, containing a fragrance is deposited onto the sheet. The device is made by partially cutting through the sheet so as to form a zone of weakness having the shape of the intended opening. After the fragrance-containing material is deposited on the sheet, it is packaged and slipped to the user. The user tears the sheet along the zone of weakness, thereby forming the opening.

Abstract: A method, apparatus, and article of manufacture for using a relational database management system to support on-line analytical processing (OLAP) systems. A relational database has a fact table and at least one related dimension table. A dimension identifier is received that identifies a data block in a multi-dimensional database. The dimension identifier comprises one or more multi-dimensional member identifiers. Rows are accessed from the fact table through the related dimension tables using the received dimension identifier. Then, the accessed rows are formatted as a data block for the multi-dimensional database.

Abstract: A method, apparatus, and article of manufacture for using a relational database management system to support on-line analytical processing (OLAP) systems. A multi-dimensional database is defined having a set of multi-dimensional data blocks and a set of identifiers comprising selected dimensions of multi-dimensional data for identifying particular ones of the multi-dimensional data blocks. The set of identifiers provides an ordering of the multi-dimensional data blocks using multi-dimensional member identifiers and holds usage information and age information about the multi-dimensional data blocks. The data in the set of multi-dimensional data blocks is stored in a relational database that represents the multi-dimensional database. Then, a set of rows representing a multi-dimensional data block is accessed from the relational database.

Abstract: Disclosed is a deck of rectangular playing cards usually having two substantially parallel long edges and two substantially parallel short edges, substantially all cards in the deck having a front symmetrically designed with respect to both short edges, to minimize cheating by signalling with asymmetric cards. The front is usually designed to be symmetrical with respect to the short axis, and preferably the long axis as well, of each card. Generally, the deck includes at least 52 cards, thirteen in each of the four standard suits, spades, hearts, diamonds, and clubs. Frequently the symmetry is obtained by the use of at least one "double-pip" in the front of the card. A "double-pip" consists of a single pip of a suit having asymmetric pips, the pip placed generally end to end with its mirror image to create a single symmetric rather than asymmetric pip of the suit. Sometimes "reversed pips" are also used. A "reversed pip" is merely a pip placed upside-down on the front rather than right side up.
