Abstract: Systems and method for enhancing search functionality provided to a user. In certain aspects, a query processing engine automatically decomposes queries into constituent units that are related to concepts in which a user may be interested. The query processing engine decomposes queries into one or more constituent units per query using statistical methods. In certain aspects, no real world knowledge is used in determining units. In other aspects, aspects of world and content knowledge are introduced to enhance and optimize performance, for example, manually using a team of one or more information engineers.

Abstract: A modular data and storage management system. The system includes a time variance interface that provides for storage into a storage media of data that is received over time. The time variance interface of the modular data and storage management system provides for retrieval, from the storage media, of an indication of the data corresponding to a user specified date. The retrieved indication of the data provides a user with an option to access specific information relative to the data, such as content of files that are included in the data.

Abstract: In a system and method for a payout in the form of paper tokens from a gaming machine, the system includes a hopper for dispensing the paper tokens, a cassette for containing the paper tokens, and software for controlling the operations of the payout of the paper tokens from the gaming machine. The cassette and hopper are located in the gaming machine in plain view of a player, and are locked for security purposes. Each paper token is transported through a payout path by mechanisms in the cassette and the hopper which interact to dispense a paper token. A plurality of sensors sense the transport of the paper token through the payout path, the operation of the transport mechanism, and the status of the paper token supply. An escrow area is provided in the cassette for rejected paper tokens, as sensed by sensors and diverted by a diverting mechanism into the escrow area. A memory element in the cassette stores operational information regarding dispensing of the paper tokens.
