| 20150370590 | HYPERVISOR CONTEXT SWITCHING USING A TRAMPOLINE SCHEME IN PROCESSORS HAVING MORE THAN TWO HIERARCHICAL PRIVILEGE LEVELS - In a virtualized computer system operable in more than two hierarchical privilege levels, components of a hypervisor, which include a virtual machine kernel and virtual machine monitors (VMMs), are assigned to different privilege levels. The virtual machine kernel operates at a low privilege level to be able to exploit certain features provided by the low privilege level, and the VMMs operate at a high privilege level to support execution of virtual machines. Upon determining that a context switch from the virtual machine kernel to a VMM is to be performed, the computer system exits the low privilege level, and enters the high privilege level to execute a trampoline that supports context switches to VMMs, such as state changes, and then the VMM. The trampoline is deactivated after execution control is switched to the VMM. | 12-24-2015 |

| 20150371036 | DEVICE SIMULATION IN A SECURE MODE SUPPORTED BY HARDWARE ARCHITECTURES - A secure mode of a computer system is used to provide simulated devices. In operation, if an instruction executing in a non-secure mode accesses a simulated device, then a resulting exception is forwarded to a secure monitor executing in the secure mode. Based on the address accessed by the instruction, the secure monitor identifies the device and simulates the instruction. The secure monitor executes independently of other applications included in the computer system, and does not rely on any hardware virtualization capabilities of the computer system. | 12-24-2015 |

| 20080300059 | Gaming Network Using Host-Configured Networking Protocols - Methods and systems for using user-configured networking protocols in wagering game networks are described herein. In one embodiment, a computer-implemented method for using user-configured networking protocols includes receiving values for one or more user-specified options associated with a gaming device and receiving a network address request originating from the gaming device. The computer-implemented method can also include transmitting a reply destined for the gaming device, wherein the reply includes a network address and the values for the one or more user-specified options. | 12-04-2008 |
| 20090036217 | SERVICE-ORIENTED GAMING NETWORK ENVIRONMENT - A gaming services framework includes web services extensions and comprises a set of services, protocols, XML schemas, and methods for providing gaming system functionality in a distributed, network based architecture. Systems and methods provide a service-oriented framework for gaming and property management based upon internetworking technology and web services concepts. One aspect of the systems and methods includes a loosely coupled architecture that consists of software components that semantically encapsulate discrete functionality (self contained and perform a single function or a related group of functions—the component describes its own inputs and outputs in a way that other software can determine what it does, how to invoke its functionality, and what result to expect). These components may be distributed and programmatically accessible (called by and exchange data with other software) over standard internetworking protocols (TCP/IP, HITP, DNS, DHCP, etc.). | 02-05-2009 |
| 20090156313 | Scheduling of reconfigurable gaming machines - A controller of gaming machines that permit wagering on wagering games includes a first memory location that stores a first time-based schedule of gaming actions to be taken by the gaming machines that are located remote from the controller. A second memory location stores identities of first gaming machines. One of the first and second memory locations stores a pointer that links the other of the first and second memory locations and associates the first gaming machines with the first schedule so that one of the first schedule and first gaming machines can be modified independent of and without modifying the other of the first schedule and the first gaming machines. A data transmitter transmits instructions corresponding to the gaming actions defined by the first schedule to the first gaming machines. | 06-18-2009 |
| 20090264203 | CONFIGURABLE WAGERING GAME MANAGER - Methods and systems for monitoring and/or servicing wagering game machines are described herein. In one embodiment, a method includes receiving a request to configure wagering game manager content, wherein the request is associated with a user identifier. The method can also include transmitting another request and the user identifier, and receiving and presenting configuration options, where the configuration options determine from which of a plurality of application servers that services can be requested. Additionally, in some embodiments, the configuration options determine separate modules for presenting information about the services. The method can also include receiving one or more configuration selections associated with the configuration options. | 10-22-2009 |
| 20100035690 | Information Flow Control for Gaming Machines Requiring Server Support - A computing apparatus operating as a gaming machine permits wagering on games. A browser generates a request for information contained on a remote server. An intermediate client-side processing, ICSP, engine coupled with the browser receives the request and generates a corresponding request that is transmitted to the remote server. The browser, following the transmission of the first message, being released to process other actions without having yet received a reply to the first message. | 02-11-2010 |
| 20100048291 | PROCESSING USER INFORMATION IN WAGERING GAME SYSTEMS - Techniques for processing user information in wagering game systems are described herein. In some embodiments, a system includes a first wagering game system to assign a first set of access credentials to a user, wherein the first wagering system is connected to a first set of wagering game machines. The system can also include a second wagering game system to assign a second set of access credentials to the user, wherein the second wagering system connected to a second set of wagering game machines. The systems can also include a master identifier controller to receive and store the first and second sets of access credentials, to receive requests to access the first wagering game system based on the second set of user access credentials, and to facilitate access the first wagering game system based on the second set of user access credentials. | 02-25-2010 |
| 20100167817 | Display of the status of gaming machines - A controller of gaming machines includes an input/output module adapted to receive signals that represent a current status of a parameter of the gaming machines. A microprocessing unit generates for each gaming machine(s) an icon having variable visual indicia indicative of a value of the parameter being monitored. The microprocessing unit automatically changes in substantially real-time the visual indicia associated with the icon to reflect a change in the status of the parameter of an associated first gaming machine in accordance with a first received signal. | 07-01-2010 |
