  • Patent number: 6824467
    Abstract: A video gaming machine simulates a real physical game, such as pachinko, by providing a mathematical model of the game including rules governing movement of an object placed in motion in accordance with a set of initial conditions. A pay table for the game is developed by creating a list of outcomes, assigning a probability of occurrence to each outcome, assigning a win amount to each outcome, and determining a pay table percentage by multiplying each outcome's probability of occurrence by its win amount and summing the products for all of the outcomes in the list. Creation of the list of outcomes and assignment of probabilities of occurrence may be effected by a Monte Carlo test. The game is played by randomly selecting a set of initial conditions and running them through the model.

  • Patent number: 6790143
    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: 6739975
    Abstract: A gaming system method uses typically a wireless communication device, and includes the following steps: Call data is provided identifying a gaming system player. This would normally be a typical identifying number plus a PIN number. A call is initiated from the wireless communication device (such as a cell phone) through a telephone call network to a financial center, requesting a cash transfer. Based on the call data, the transfer is credited to the wireless communication device or to a casino, to the credit of the player. Upon receiving of the predetermined balance of the cash transfer, one may communicate, using the wireless communication device, to transfer a portion or all of the predetermined cash balance from the wireless communication device or casino to the credit of a particular gaming machine, thus enabling the gaming machine for play just as if physical cash has been provided to it.

  • Patent number: 6732501
    Abstract: A ventricular apex connector for quick connection and disconnection of an inflow tube of a ventricular assist device, comprising a sewing ring, a cylindrical ring, gripping pins, a spring ring and a sealing O-ring is provided. The cylindrical ring defines two openings, diametrically opposed to each other, in its walls. Gripping pins, comprising rods with gripping pads, are placed in the openings in the cylindrical ring so that the gripping pads are at rest within the inner circumference of the cylindrical ring. The spring ring is placed around the cylindrical ring and the rods of the gripping pads, which extend out of the outer wall of the cylindrical ring, are welded to the spring ring. The gripping pins are thus biased towards each other by the force of the spring ring. When the spring ring is squeezed, at points away from the gripping pin connection points, the deformation of the spring ring causes the gripping pads to be pulled out towards the inner wall of the cylindrical ring.

  • Patent number: 6616650
    Abstract: A therapeutic agent is applied to an internal tissue site of a patient by advancing typically a catheter into the patient to cause a portion of the catheter, typically a catheter balloon, to occupy the internal site. The balloon portion of the catheter carries the therapeutic agent, usually mixed with a controlled release carrier for the agent, typically on an outer surface of the section, to permit release thereof from the catheter balloon at the internal tissue site so that the therapeutic agent is locally applied to the internal tissue site.

  • Patent number: 6613043
    Abstract: A method and apparatus are provided to increase the accuracy and safety of ablative laser treatments of the eye. In an illustrative embodiment, tissue is removed from the cornea, via a laser, to provide an effluent from the cornea. The effluent is aspirated and deposited into a chemical analyzer. The amount of effluent that has been deposited is quantitated. Data relating to a dimension of the ablated cornea is inputted to a computer and data relating to the quantitized effluent is also inputted to the computer. The computer uses the quantitized effluent data and the inputted dimension data to estimate the number of diopters of treatment accomplished. The estimated number of diopters of treatment accomplished is compared to a desired number of diopters of treatment and the laser treatment is modified based on the comparison for most accurate optical results.

  • Patent number: 6609978
    Abstract: A gaming system and method facilitating electronic fulfillment of prizes is provided. A electronic message is sent from a gaming terminal or casino, in response to winning at least certain prizes, such as non-monetary prizes, to a fulfillment entity. Fulfillment entities which are not a part of or controlled by the casino may be retail entities such as Internet retail entities. In one embodiment, the fulfillment entity selects or formulates a web page displaying a prize or a selection of prizes for display to a user at the gaming terminal. When several prizes or prize options are displayed, the user may select a desired non-monetary prize, e.g. using a touch screen keypad and the like. The prize fulfillment entity delivers the prize preferably at a location selected or preferred by the user, e.g. using mail, parcel delivery and the like.

  • Patent number: 6592458
    Abstract: A gaming system incorporating a non-deterministic jackpot is provided. In a first embodiment, the gaming system generates a random number to determine a probability of winning and a jackpot amount. A contribution rate is predetermined, and a portion of each bet placed on a gaming machine associated with the system equal to the contribution rate multiplied by the amount of the bet is placed in a contribution pool. The gaming machine on which a bet causing the contribution pool to be greater than or equal to the jackpot amount is awarded the jackpot. According to a second embodiment of the present invention, a first random number within a range is generated. A second random number is generated for each bet placed on a gaming machine associated with the system. The jackpot is awarded to a gaming machine on which a bet resulting in a second random number equal to the first random number was placed.

  • Patent number: 6585592
    Abstract: A gaming system is provided which permits the hold value to be determined independently of the distribution of winning outcomes, e.g., to avoid or prevent volatility in the hold value. Preferably each time a wager is placed, a hold value (such as a predetermined and/or fixed percentage) is retained and the remainder is allocated to one or more prize pools. If a pool is too large or too small, or if a pool's rate of growth is too large or too small, the central computer sends a message to all terminals which contribute to the pool, causing the terminals to modify operations so as to bring the pool size or rate of growth to within desired target ranges. Preferably, the current prize amounts corresponding to various potential winning game outcomes are displayed when a game is won, the displayed amount corresponding to the type of win paid. Preferably, a portion of wages is retained as a background amount to at least partially replenish a paid-out prize.
