  • Patent number: 8348746
    Abstract: Methods for emulating rotating physical reels on a display screen are disclosed. Graphics for “static” reel symbols are intentionally blurred for those reel symbols “in motion.” Gaming machines include an exterior housing, master gaming controller, display device and virtual reels. Virtual reels include reel stops, static reel symbols and corresponding dynamic blurred reel symbols. A blurred reel symbol generator provides corresponding blurred reel symbols for existing static reel symbols, and can be located at a remote host and/or within the gaming machine. A remote host can provide downloadable virtual reel strips, reel symbols and blurred reel symbols to gaming machines. The blurred reel symbol generator can accept manually entered blurred reel symbol images, and/or can also generate blurred reel symbol images itself in automated fashion. Blurred reel symbols can be generated on the fly at runtime, or can be taken from a stored location.

  • Patent number: 8348750
    Abstract: A printer on a networked gaming device can be controlled by the network to generate awards. The printer can operate as both a typical printer in a gaming device and as a printer for the gaming network, or separate printers can be installed in the gaming device. If the particular player has identified himself or herself to the gaming network, then the gaming system has a very high probability that it is communicating to a known player. Therefore, the printer operates as a direct communication conduit to a player. Additionally, previously issued awards can be redeemed by a validator coupled to the gaming network.

  • Patent number: 8346686
    Abstract: Methods and apparatus are described for modeling sequences of events with Markov models whose states correspond to nodes in a provided taxonomy. Each state represents the events in the subtree under the corresponding node. By lumping observed events into states that correspond to internal nodes in the taxonomy, more compact models are achieved that are easier to understand and visualize, at the expense of a decrease in the data likelihood. The decision for selecting the best model is taken on the basis of two competing goals: maximizing the data likelihood, while minimizing the model complexity (i.e., the number of states).

  • Patent number: 8342953
    Abstract: The present invention provides novel method and devices for managing gaming machine networks. In some implementations, switches report the gaming machines that are currently connected to the switch. The report may be made periodically, in response to a query and/or in response to an event (such as the connection of a new gaming machine). The report may be made to a host device or may be used to automatically update a connectivity table. Some implementations provide for a display of the current connectivity of gaming machines and associated switches according to the report. Some implementations also display the prior connectivity of the gaming machines and associated switches according to a previously stored connectivity table. The display may be a graphical user interface (“GUI”) that allows a user to, e.g., resolve discrepancies between the current connectivity and the prior connectivity and update stored connectivity table.

  • Patent number: 8347192
    Abstract: Parallel Reed Solomon error correction can be performed using dot products in finite fields while factoring out multiplier reduction. A finite field accumulator with left and right shifts of the polynomial dot products is used to generate the final result using a fixed dot product core and a small number of post processing Galois Field multiplies. An efficient Reed Solomon decoder for transmission, storage, and processing operations can be implemented in a small area while being easily scalable.

  • Patent number: 8343686
    Abstract: Tubular objects having two or more concentric layers that have different properties are joined to one another during their manufacture primarily by compressive and friction forces generated by shrinkage during sintering and possibly mechanical interlocking. It is not necessary for the concentric tubes to display adhesive-, chemical- or sinter-bonding to each other in order to achieve a strong bond. This facilitates joining of dissimilar materials, such as ceramics and metals.

  • Patent number: 8341235
    Abstract: The disclosed embodiments provide for an email and messenging system that allows a user composing a message to select an application which will appear next to the composition screen at both the sending and receiving computer. The application is specified as an attachment at the sending client and when received at a receiving client of a user with an enhanced or compliant mail/messenging account the application will be executed at the receiving client, thus customizing the functionality of the receiving client computer and the mail experience between sender and receiver. An unapproved application sent as an attachment will not be executed and/or alter the receiving client interface. Similarly, the application will simply appear as a standard attachment at a non enhanced recipient client/account.
