Abstract: An improved padding system for a helmet and process for designing the padding system are described. In one example, a helmet for an individual can include an outer shell having an inner surface. The helmet can further include a padding system coupled to the inner surface. The padding system can include pad clusters that are respectively positioned at different locations on the inner surface. Each of the pad clusters can include discrete pads that are individually coupled to the inner surface in a defined arrangement. In one example, the defined arrangement can be a certain arrangement that allows the discrete pads to collectively provide a desired system stiffness for the padding system. The desired system stiffness in this example can be a certain system stiffness that can reduce at least one of peak linear or peak rotational accelerations to the head of the individual during an impact.

Abstract: The present invention provides a method for testing a helmet that uses a risk function that incorporates both linear and rotational acceleration to predict the helmet's ability to prevent a concussion. In certain embodiments, the testing matrix includes 3 impact energy levels and 4 impact locations, for a total of 12 testing conditions per helmet.

Abstract: A novel method of playing a poker-type game is disclosed wherein in a single deal a player is given the opportunity to bet twice against posted house odds, bet against a dealer hand, and bet against the other players. Each player makes initial wagers against the house odds and the other players. Each player and the dealer are then dealt two cards. In addition two community cards are dealt face down. Each player decides independently whether to bet against the dealer. The first community card is turned over and is used by each player and the dealer to form a three-card hand. Each player's two-card hands are compared to the house odds and the first bet is settled. The second bet against the house odds and any additional bets against the dealer's three-card hand are settled. The second community card is turned over and used by each player to form a four-card hand that is used to determine the winner of the bet against the other players.
