  • Patent number: 8621503
    Abstract: Apparatuses, system, method, and storage medium for crowd game are disclosed. A series of missions forming a crowd game are outputted to a display device, each mission specifying a task for spectators of an event. A result for a mission is determined on the basis of participation and/or reaction by the spectators for the task. A total result for the crowd game is determined on the basis of the results for the missions.
    Type: Grant

  • Patent number: 8019294
    Abstract: There is provided a control circuit of a switch mode power supply including a random number generator configured to form an optimized n-degree polynomial based on the minimum power-on cycle time in order to form a uniform distribution of output signals, a switch control block configured to control output signals of the switch control block such that the complementary output stages of the switch control block conduct at different times on the basis of the output signals received from the random number generator. and a dither control block configured to generate a synchronized dither current by minimizing glitches at each differential stage of a default reference current based on the output signals received from the switch control block, and to combine the generated synchronized dither current with a reference current of a voltage ramp generator.

  • Patent number: 4722154
    Abstract: A room unit (1) and a method for the construction and the position mounting of the box-like room unit (1), for instance a cabin, a module assembled from room elements or the like. The room unit intended for an arrangement operable in marine enviroments, for instance for a ship, an offshore construction or the like. The room unit is located on an at least mainly even underlaying (14) of the arrangement, for instance on a ship's deck (14). The method comprises the inclusion of the room unit (1) with a roof (4), walls (2,3) and a floor (12), the lower portion of the wall (2,3) being attached at the outer edge of the self-supporting floor (12). The floor (12) is provided by adjustable damping appliances (21) operable from the interior of the room unit (1). The moving of the room unit (1) is carried out by supporting the unit (1) temporarily at a bag-like air cushion device and at one stabilizing device at least.
