Abstract: A controller for controlling the intensity of an electroluminescent display is disclosed. The controller controls a number of skipped cycles in a cycle set of an applied waveform to the electroluminescent display to vary the average duty cycle, and thereby adjust the intensity of the electroluminescent display. The controller is further configured to adjust the intensity of individual channels within the electroluminescent display to provide compensation for display aging, color variation, as well as for varying intensity for various operating modes.

Abstract: A gaming apparatus and method first determines an outcome, and then maps that outcome to a symbol which is displayed to a player. In general, for each possible outcome, there may be a plurality of possible symbols, and the system selects a symbol by a random selection technique. The method can be practiced both for lottery-type games and non-lottery games. In the case of lotteries, the system determines the outcome by selecting a game set element from a finite pool, each game set element being associated with a particular value. The system then maps the game set element to an appropriate symbol to be displayed to the player. In another embodiment, the system can be programmed to allow the results of the game to be affected by the skill of the player. If the player plays optimally, the system can award the maximum possible value. If the player plays in a sub-optimal manner, the system can award an amount which is less than or equal to the maximum.

Abstract: The present specification discloses a flexible, adapable voucher gaming system having a LAN interconnecting a cashier terminal, a central voucher-record database server, one or more logical gaming controllers, and a plurality of player terminals in order to play games of chance at each player terminal. The system provides voucher printers at the cashier terminal and preferably at the player terminals as well. The vouchers include unique bar codes printed on the vouchers, and the bar codes are readable by scanners at the cashier terminal and at the player terminals. The player terminals are preferably adapted to provide the player with the option of receiving at least certain amounts of cash rather than a voucher, but to also ensure that at least a voucher is provided to the player in the event that the player terminal fails to dispense cash when earned by the player and payable to the player under the game rules at the player terminal.
