Abstract: Hall sensor arrangement is disclosed for detection of the change in the position of two components which can move relative to one another into two end positions, with a Hall sensor with at least one Hall measurement field (H; H1, H2) and a field magnet. An actuator is provided for transmitting to the Hall sensor the change in the position of the two components which can move relative to one another. The Hall sensor and the field magnet are combined into a preassembled structural unit. When the position of the field magnet changes relative to the Hall sensor from one end position into the other end position the polarity of the magnetic field acting on the Hall measurement field (H; H1, H2) can change, e.g., the polarity becomes reversed.

Abstract: A game wherein players identify the title and/or artist of a song after listening to several notes. The apparatus has a variable number of freeze buttons, a scan continue button, a compact disk player, a logic circuit, a universal remote control, a timer and a buzzer. The disk player loads at least 3 compact disks, and has remote pause, disc skip and play functions. The scan poker CD player program charts are designed for at least 31 track programmable CD players. The method includes determining the scan operator and banker, beginning the game, correctly identifying a song, incorrectly identifying a song and terminating the game. The game continues for a player until he runs out of money, refuses to ante up or acquires a predetermined number of points. It also ends if the game is not resolved in one round, where the game is over and the scan poker operator collects the pot.
