  • Patent number: 7166028
    Abstract: Gaming methods and devices that include a primary game and a bonus game. In the primary game, one or more paylines of an array are selected. One symbol from a predetermined set is then randomly assigned to each image site of the array. Awards are granted when certain combinations of symbols appear on one or more of the paylines that were selected by the player. A bonus game may be awarded for each selected payline of the primary game on which a triggering event occurs. In each bonus game, one or more of the symbols along the corresponding primary game payline may be randomly replaced with other symbols from the predetermined set. If multiple bonus games are awarded, the bonus games may be played sequentially. An additional bonus event may also be awarded if a triggering event occurs in a predetermined or prespecified location of an array of image sites.

  • Patent number: 4902953
    Abstract: A motorized window blind actuator including input means for receiving regulated voltage and first variable reference voltage signal. A motor having an output shaft which connects to the window blinds to open and close the window blinds is controlled by a controller/driver component. A transducer is operatively associated with the output shaft of the motor to assist in producing a second voltage reference signal which is related to the actual position of the motor output shaft, and in turn related to the actual position of the slats of the window blind. The first voltage reference signal is related to the desired setting and position of the window blind. First and second voltage reference signals are continually compared. If they are sufficiently different, the motor is directed by the controller/driver to adjust the window blinds until signals are sufficiently the same, or, until the output shaft of the motor hits physical limits which cause an over current situation resulting in stoppage of the motor.
