Abstract: A gaming system includes circuitry and associated methodology for detection of continuity along one or more sensing paths for determination of the presence and proper seating of one or more component boards to each other and a backplane, having an arbitrary number of couplings. The invention controls voltage to one or more components of the gaming system, enabling selective activation of various components, on one or more of the connected boards, based on the proper seating of component boards to each other and a backplane. The invention implements dynamic configuration of sensing paths (defined by signal paths and signal traversal) and subsequent continuity detection through interfacing connector/port pairs, in combination with specifically placed electronic components and local ground connections along the sensing paths, to control powering selective system components based upon a detection of the presence and proper seating of multiple component boards to each other and a backplane.

Abstract: A gaming system internally secures a modular, critical-electronics central processing unit (CPU) box enclosure having various security features, a power source, a power regulator module, a removable fan assembly, and a backplane providing connection between all the other elements contained within the housing. The removable fan assembly is a modular, hot-swappable, encased unit that provides air flow in a plurality of directions using a corresponding plurality of individually sensed and controlled fans. The fan assembly can be removed during operation of the wagering game machine without interfering with the operations of any other electronic component and without breaking one or more validated seals of the enclosure, the validated seals enabling the gaming system to perform a wagering game having regulatory approval in a given jurisdiction. The removable fan assembly is coupled to one or more processing units that detects, monitors, and controls the operation of the individual fans the fan assembly.

Abstract: A method and system for performing document image correction using a document reader is disclosed. The method includes generating a document image representative of a document having a deformation; decoding an optical pattern embedded in the document from the document image to determine an optical signature for the document; receiving document classification data associated with the optical signature; and applying an image correction technique to the document image based on the document classification data to generate a corrected document image. A document capable of being read by a document reader is also disclosed. The document includes a substrate and an optical pattern embedded on the substrate. The optical pattern is part of a background pattern printed on the substrate. The optical pattern defines an optical signature unique to the particular class of document and is associated with document classification data for the document.
