In a collective control of plural game machines placed in the same parlor, it is detected whether there is player change on each game machine and, based on the detection result, the credit cumulative consumption on each game machine is managed player by player. When the credit cumulative consumption of a certain player reaches a predetermined upper limit, payout return is executed to this player. The display status and non-display status of information about the upper limit can be switched depending on the play status. Therefore, the player can perform a game without anxiety while enjoying amusement of the game. As the result, the problem of missing customers is eliminated.

Adaptive system and method for interacting with and navigating 2D and 3D audiovisual content by interpreting the side to side and / or up and down physical gestures and sounds of a multi-person audience. The system may be used in a movie theatre, stadium, music arena, or other venue where an audience views the same view screen. A camera pointed at the audience captures audience motion and a microphone captures sounds. Optical flow is determined by comparing successive video frames. A Motion Index between −100 and 100 is calculated using Optical flow, comparing more recent Optical Flow vectors with previous values. Methods are provided to give equal weight to audience members closer to and further from the camera. Motion Index Values are used to control and interact with content scenarios.

A motor structure resistant to liquid intrusion features two modules, the first having an electronically commutated external-rotor motor (20), which motor comprises an internal stator (22) that is arranged on a bearing tube (30) and is separated by a first air gap (24) from an external rotor (26; 92), which latter comprises a rotor cup (40) that is open at one end and is joined at its other end to a shaft (46) that is journalled in the bearing tube (30), further having a permanent-magnet arrangement (76), arranged at the open end of the rotor cup (40), for magnetic interaction with a second permanent-magnet rotor (92), forming part of the second module. The first module is separated from that second rotor (92) by a second air gap and forms therewith a magnetic coupling (94), so that a rotation of the permanent-magnet arrangement (76) brings about a rotation of that second rotor (92). A hermetic separation of the two modules is accomplished using a non-ferromagnetic separating element (82) arranged in the second air gap. The second module can safely be used to handle liquid, e.g. as a pump.

The present invention provides a plenum configured to evenly separate and distribute airflow generated by a fan into distribution lines of an agricultural machine. The plenum can utilize angled vanes symmetrically or asymmetrically arranged to form plenum chambers to provide a balanced airflow which contributes to maximizing fan efficiency, including power consumption and performance (airflow and static pressure). Accordingly, the plenum can be configured to separate the airflow and minimize imbalance between the lines during sectional control. The plenum height can be maintained for increased manufacturability and to prevent additional expansion. The plenum length can be configured within allowable space constraints of the machine yet allow airflow to develop upon separation into the lines. Vanes throughout the span of the plenum initially divide the airflow from the fan and maintain separation until the outlets.
