System and method for remote roulette and other game play using game table at a casino

Abstract: A system and method for playing a table type game such as roulette or dice in an interactive manner at a site remote from the actual casino table in which a camera follows a game that is being played at a table in a casino and a microphone can also pick up the sound of the players at the table and the game play. Terminals at various locations in the casino remote from the table, or various devices such as a personal computer at other remote locations, receive the video display of the game play and the players, as well as game results and game betting status signals from a distribution device that can be closed circuit, wireless satellite or Internet. The remote terminal or device displays a picture (video) of the actual casino table where the game is being played and also contains its own computer (microprocessor) that has various functions which include the generation and display of an electronic representation of a table betting grid. The player at a terminal uses a touch type keypad or at a remote device uses a mouse to electronically places a bet. The remote terminal or device microprocessor is programmed with the required information of odds to pay off when the player makes a winning bet. The terminal or device maintains a running status of the player's account.

Speech recognition system having an interface to a host computer bus for direct access to the host memory

Abstract: A signal processing card packaged on a bus of a personal computer has a bus master which is used to access the main memory of the personal computer. A large table of probability values required for speech recognition is held in the main memory. When a label to be processed is generated, only the necessary part of the table is read from the main memory to the memory on the signal processing card by direct memory access transfer to perform speech recognition processing.

A novel linear programming approach to fluence map optimization for intensity modulated radiation therapy treatment planning.

Abstract: We present a novel linear programming (LP) based approach for efficiently solving the intensity modulated radiation therapy (IMRT) fluence-map optimization (FMO) problem to global optimality. Our model overcomes the apparent limitations of a linear-programming approach by approximating any convex objective function by a piecewise linear convex function. This approach allows us to retain the flexibility offered by general convex objective functions, while allowing us to formulate the FMO problem as a LP problem. In addition, a novel type of partial-volume constraint that bounds the tail averages of the differential dose-volume histograms of structures is imposed while retaining linearity as an alternative approach to improve dose homogeneity in the target volumes, and to attempt to spare as many critical structures as possible. The goal of this work is to develop a very rapid global optimization approach that finds high quality dose distributions. Implementation of this model has demonstrated excellent results. We found globally optimal solutions for eight 7-beam head-and-neck cases in less than 3 min of computational time on a single processor personal computer without the use of partial-volume constraints. Adding such constraints increased the running times by a factor of 2-3, but improved the sparing of critical structures. All cases demonstrated excellent target coverage (> 95%), target homogeneity (< 10% overdosing and < 7% underdosing) and organ sparing using at least one of the two models.
