Abstract: Convertible rails for selecting player-tracking modes in an electronic game table are described. In one implementation, a rail or trim surrounds the periphery of the tabletop of an electronic game table. The rail has recessed bay openings for mounting user-interface hardware, such as for player-tracking. Player-tracking hardware may include, for example, touch-screen displays for manual input of user information, and player-identification card readers. A proprietor may install interchangeable rail section covers to expose some, all, or none of the bays. Thus, in a non-tracking mode, the bays may be covered, while in a tracking mode, some degree of player-tracking hardware mounted in the bays may be exposed to the user. In other implementations, interchangeable covers hide bays or expose hardware mounted on the tabletop itself.

Abstract: Bio-waste sterilizers are described. In one implementation an exemplary system has waste transport vessels that can be intermittently heated and pressurized, for example, with steam, and are interconnected to provide multiple sterilization pathways for waste as the waste is transported. Selected sterilization pathways may depend on attributes of the waste. Sterilization factors, such as mechanical shredding, application of steam, application of pressure, maintenance of temperature, separation of liquid, etc., are integrated into the waste transport features of the system, which can be made compact to save space while processing relatively large bulk amounts of materials, such as medical wastes. The system maintains safe isolation of bio-hazardous components in the waste from the external environment. A system controller provides parameters management, smart sterilization cycle control, quality assurance, safety management, diagnostics, and reporting over a network.

Abstract: Composite tabletops for electronic game tables are described. In one implementation, the composite tabletop has a channeled core layer sandwiched between a bottom layer and top layer. The channeled core layer is constructed of foam, so that the foam forms enclosure spaces for player stations, displays, user-interface hardware, central control/server hardware, and cooling equipment. The foam is also shaped to form duct spaces between each player station and a central space in the channeled core layer. The ducts can be used to route wires between each player station and the central space and to direct cooling air to or from each player station. The channeled core layer reduces time and labor during manufacture of an electronic game table and results in an electronic game table that is more lightweight for shipping, absorbs noise generated by enclosed hardware and electronics, absorbs shocks, and optimizes cooling of enclosed components.

Abstract: Systems and methods remove and manage heavy metals. In one implementation, an exemplary method can be applied to food processing and food consumption to remove heavy metals such as mercury, lead, uranium and cadmium before absorption by a living organism. The exemplary method exposes the food to a heavy-metal binding ligand, such as a concentrated protein or phytic acid, to form a heavy-metal chelate, and then allows the chelate to separate from the food. In another implementation, an exemplary probe possesses innovative molecular layers on its surface to detect and quantify heavy metals by attracting and binding traces of the heavy metals on a ligand layer.

Abstract: Systems and methods for playing live casino games. The systems have changeable displays which portray virtual playing cards or symbols to live participants. Shuffling, cutting, dealing and return of playing cards are accomplished using data processing functions within an electronic game processor or processors which enable these functions to be performed quickly and without manual manipulation of playing cards. The invention allows casinos to speed play and reduce the risk of cheating while maintaining the attractive ambiance of a live table game. The systems can also be multi-user slot machines using the processor to associate or assign one or more symbols either with the virtual playing cards or as slot symbols in participant subsets. The participant subsets are compared to a predetermined list so that payoffs can be awarded on the basis of winning symbols or combinations of symbols.

Abstract: A multi-stage card game includes stages at which each player selects which unrevealed cards are to be played. In one implementation, bets are received for at least some stages of a multi-stage poker-like game. Cards are dealt into an unrevealed dealer hand and an unrevealed player hand for each player. For at least one of the stages, each player selects one of the cards from the player's unrevealed hand to reveal in order to access a progression of payout schedules. Each player's hand accumulates player-selected cards across the stages of the game and across associated payout schedules, until all cards are revealed. A player's poker hand is then compared to the dealer's poker hand for potential payout. Opportunities for bonus bets are also interjected into implementations of the game.

Abstract: Systems and methods for playing live casino games. The systems have casino tables with changeable displays which portray virtual playing cards or symbols to live participants. The displays can be controlled to show hidden cards or symbols only to the player at that player position by depressing a manual button or touching a touch screen display. Viewing by others can be prevented by using the player's hands or other means. Shuffling, cutting, dealing, betting and return of playing cards are accomplished using data processing functions within an electronic game processor or processors which enable these functions to be performed quickly and without manual manipulation of playing cards.

Abstract: A gaming apparatus and methods which include multiple virtual stacks of symbols, such as cards. In one form each player has an individual virtual stack and the dealer has one stack. In another form each player has one stack and the dealer has individual virtual stacks for each player. Other alternatives are also described.
