  • 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: 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.
