  • Patent number: 6533664
    Abstract: A gaming system is provided in which a plurality of gaming terminals have gaming outcomes that are provided in response to a game outcome seed sent, to the gaming terminals, from a central computer. The game outcome seeds are individualized in the sense that not all gaming terminals in the system use the same seed at the same time. Preferably, seeds are addressed to individual gaming terminals or groups of terminals. Seeds may be transmitted to terminals in response to seed requests output by terminals. In one approach, seeds are generated as needed and/or substantially continuously. In another approach, batches, pools or lists of seeds are generated and a seed request is responded to by drawing a seed from a pre-defined list, until the list is depleted, whereupon a new list or batch is generated. In one approach, one or more lists are generated for each type of game or pay table.

  • Patent number: 6485366
    Abstract: A single-player casino-style electronic gaming method and apparatus uses a deck of (simulated) number of cards and wild cards. The number cards each have a number and a color. In response to a wager, a number of, such as seven, cards are displayed to the player. The player may choose to discard any, all or none of the initially-dealt cards. Any discarded cards are replaced, to form a final hand. Prizes are awarded including based on how many cards of the same number and/or how many cards of the same color are in the final hand.

  • Patent number: 6476798
    Abstract: A touch screen having a high or fine resolution at relatively low cost is provided. In one embodiment, electrodes are placed directly on the surface of a CRT screen without the need for an electrode positioned on the rear surface. The touch screen may include a conductive coating and a protective coating which are preferably provided in a single vacuum chamber step. A high gain system including a high-frequency sampling bandpass filter provide discrimination of the desired signal over noise. A screen calibration technique is used to achieve linearization in order to convert the electric signals obtained from the screen into data indicative of the position of a touch on the screen.

  • Patent number: 6450883
    Abstract: A gaming machine offers a first base game to a player, in the nature of a spinning reel game. Three spinning reels spin in accordance with each play of the game. On the occurrence of certain winning combinations, constituting a triggering event, a bonus game is entered. In the bonus game three rows, respectively of two, three, and four playing cards, are arranged face down. A player is required to select one of the rows and then choose one card from that row, seeking to choose a winning card, such as a Joker. The respective odds of winning between three lines of cards are unique integer multiples of each other.

  • Patent number: 6443452
    Abstract: A gaming terminal provides at least a portion of at least one prize in the form of at least one or more free game rounds. A benefit may be calculated as the difference between the value of the prize if paid out in coins or other monetary value and the value paid out as free game rounds. In one aspect, the benefit is redistributed in the paytable, preferably so as to provide a game in which the overall, long-term averaged payback amount is unchanged by the process of converting monetary payouts to free game payouts and redistributing the benefit thereof.

  • Patent number: 6419583
    Abstract: In a gaming system, a central computer generates a plurality of game win-loss outcome stacks, each stack having at least one “win” (preferably, large-prize) outcome. Sub-stacks, from among the plurality of stacks, are transmitted to casino or other group controllers or computers, each casino controller being coupled to a plurality of gaming terminals. In response to placing a large-prize wager, in addition to normal, local game wager, a gaming terminal requests a large-prize outcome from the sub-stack which is stored in the casino controller. Whenever a casino controller's sub-stack is depleted, it requests a new sub-stack from the central computer. Preferably the central computer selects a new sub-stack for transmission according to a selection process which is weighted so as to maintain the ratio of winning outcomes to all outcomes in a predetermined range. When all sub-stacks of a given stack have been transmitted, the central computer generates a new stack to replace the depleted stack.

  • Patent number: 6383158
    Abstract: Pressure is sensed in blood flow tubing by placing an aqueous, preferably isotonic, substantially cell-free solution into branch connection tubing that connects in branching relation with the blood flow tubing at one end. The branch connection tubing also connects in use with a pressure transducer unit at its other end. An air volume is maintained, occupying a portion of the branch connection tubing which is adjacent to the other end. One flows positively or negatively pressurized blood through the blood flow tubing, with the result that the pressure of the blood is communicated through the aqueous solution and the air volume in the branch connection tubing to the pressure transducer unit, with the blood being spaced from the air volume. Preferably, substantially all of the branch connection tubing containing the aqueous solution and air volume has an inner diameter of substantially no more than 5 mm.
