Abstract: Chemically strengthened glass with high surface compression, deeper case depth, shorter processing time and a reduced induced curvature relative to that obtained in a traditional immersion method and a method for making utilizing an electric filed assist are provided. The method includes providing a substrate, characterized by having a glass chemical structure including host alkali ions having an average ionic radius situated in the glass chemical structure. The method also includes exposing the substrate to the exchange medium; and conducting ion exchange to produce a strengthened substrate while exposing the substrate to the exchange medium and applying an electric field in a plurality of cycles across the surfaces of the substrate.

Abstract: A disclosed gaming machine provides methods and apparatus for wirelessly communicating between devices within the gaming machine. The gaming machine includes a gaming machine housing to which a master gaming controller and one or more gaming peripherals can be mounted. The master gaming controller is adapted for executing a game of chance played on the gaming machine and communicating wirelessly with the one or more gaming peripherals used to play the game of chance. Furthermore, the gaming machine includes a wireless communication manager that can manage wireless communications between the master gaming controller and the gaming peripherals, between the gaming peripherals, or a combination thereof.

Abstract: An electronic gaming system includes a server and a plurality of electronic gaming machines, each machine including a logic system configured for communication with the server, a memory and a theoretical coin-out meter. The memory includes instructions executable by the logic system for running on the gaming machine a persistence game having one or more recordable persistence states leading to a redeemable persistence award. Each persistence state has a persistence value representing a portion of the persistence award. The persistence game is interruptible at a first machine and resumable at a second machine at a recorded persistence state. The theoretical coin-out meter stores unawarded persistence values accumulated by the machine from advancing the persistence game during game play among the one or more persistence states. A persistence award redeemed at one of the machines is reconciled with unawarded persistence values accumulated at another one or more of the machines.

Abstract: An electronic gaming machine (EGM) is configured to run a persistence game having one or more recordable persistence states transferable to another EGM.

Abstract: Methods and devices are provided for making, storing and retrieving electronic representations of payment documents such as payment tickets used for gaming machines. Some implementations sort currency and non-currency payment documents. According to some embodiments, electronic representations are made only of non-currency payment documents. After an electronic representation of a non-currency payment document is made, the payment document is preferably voided. Voided payment documents may be stored in a non-secure storage area, may be automatically disposed of, or may simply be ejected. Some implementations provide devices and methods for resolving payment disputes by reference to stored electronic representations of payment documents. Other embodiments read information from a payment document and make an electronic representation of the payment document without retaining the payment document. Voiding information is transmitted to, e.g.

Abstract: A method and apparatus for communicating gaming machine settings is disclosed. In one embodiment a universal configuration communication protocol is provided for retrieving or modifying, over a network, current gaming machine setting of a remotely located gaming machine. A translation table may be implemented with the communication protocol to achieve variable translation between different gaming machine platforms. In one embodiment the gaming machine status is requested prior to activating the communication protocol to prevent interruption of game play. In one embodiment activation of the communication protocol may result in the gaming machine momentarily entering an inactive status.
