20100062844 | AUTHENTICATION AND VALIDATION SYSTEMS FOR GAMING DEVICES - Systems and methods for authenticating and validating a device are disclosed herein. In one method, a manifest file is created for a gaming component, wherein the manifest file includes contents of each file from the gaming component. A digital signature is generated for each file from the gaming component, wherein the digital signature is created by using the contents of each file. Each digital signature is saved with each file in the manifest file. A digital signature calculation is performed on a file accessed during a bootup process. The contents of the accessed file are validated by comparing the calculated digital signature to the saved digital signature, and an error message is presented on a video display when the contents of the accessed file is not validated. | 03-11-2010 |
20100120526 | CO-PROCESSOR ASSISTED SOFTWARE AUTHENTICATION SYSTEM - A system and method of using a main processor and a co-processor to authenticate software and execute software reduces processing loads, by distributing processing requirements between authentication and software execution. This system requires less code to perform software authentication, because the software does not need to instruct the main processor to both authenticate and execute the software. In this manner, the co-processor frees up processing capability on the main processor, which can result in improved game play. | 05-13-2010 |

20100123286 | GAMING METHOD HAVING GAMING MACHINES WITH PROJECTED OR POLARIZED IMAGE REEL SYMBOLS - A method for providing a multi-game gaming machine having mechanical reel strips is displayed. The use of the projection devices onto blank mechanical reel strips transforms the multi-game gaming machine to a mechanical reel video game. These projection devices project the multi-game symbol images over the exposed portions of the mechanical reel strips. The projection devices are to be positioned such that its image projection covers one, two, or three reels of the available viewable area. The multi-game symbol projected images are theme based and can be easily changed or updated. A mechanical-reel gaming machine may include light responsive polymer material layers on its reel strips having multiple symbol images visible in polarized light and methods for displaying such symbol images is disclosed. The multi-game gaming machine has access to visually changing reel strips, and as such a number of sets of symbols can be displayed based on a game selection and corresponding image polarizer orientation. Back lights for each mechanical reel are to provide a uniform light source, and enough light coverage for all viewable reel payline positions. The uniform light sources per reel work with the image polarizer associated per reel, with polarizer location between preferably the reel and the game patron or the light sources and the reel. The polarizer orientation changes based on a game selection, with different game symbols displayed according to that selected game. | 05-20-2010 |

20100125851 | APPARATUS, METHOD, AND SYSTEM TO PROVIDE A MULTI-CORE PROCESSOR FOR AN ELECTRONIC GAMING MACHINE (EGM) - An electronic gaming machine (EGM) implements a multi-core processor. A first of the processor cores is adapted to perform or otherwise control a first set of operations. The first set of operations can include, for example, game manager operations and other operations of the EGM that are more time-sensitive. A second one of the processor cores is adapted to perform or otherwise control a second set of operations. The second set of operations can include, for example, operations related to multimedia presentation associated with the running/playing of a game and/or other operations of the EGM that are not time-sensitive or are otherwise less time-sensitive than the operations performed/controlled by the first processor core. Each of the processor cores may run an operating system that matches the needs of its respective processor core. | 05-20-2010 |
20110111865 | BACKGROUND MEMORY VALIDATION FOR GAMING DEVICES - Various embodiments are directed to a gaming device including a background memory validation system. The background memory validation system includes a background kernel thread that validates read-only pages on the gaming device. Additionally, the background kernel thread also minimizes potential timing problems because this process only validates page content in memory that is fully-loaded and functional. | 05-12-2011 |
20110119474 | Serial Peripheral Interface BIOS System and Method - Various embodiments disclosed herein are directed to a serial peripheral interface-based (SPI-based) BIOS system for improved upgrading of a BIOS software image in a gaming machine. The system includes a flash BIOS chip and a SPI BIOS chip. The flash BIOS chip is operable to be written to by an Intel chipset for storage of an onboard Ethernet controller's information, wherein the flash BIOS chip may contain a new BIOS software image. The SPI BIOS chip comprises a traditional BIOS including gaming extensions to the BIOS. The SPI BIOS chip can be disabled from write actions at a jumper/circuit level. When a SPI BIOS write enable jumper circuit is ON, a write protect pin of the serial peripheral interface BIOS is in the disabled state. In this regard, when the write protect pin is in the disabled state, the SPI BIOS content may be updated to the new BIOS software image from a BIOS install compact flash. When the BIOS write enable jumper circuit is OFF, the write protect pin of the serial peripheral interface BIOS is in enabled state. In this regard, when the write protect pin is in the enabled state the serial peripheral interface BIOS content cannot be updated | 05-19-2011 |
