  • Patent number: 8176853
    Abstract: An amusement park ride adapted for fully rotating a passenger compartment in response to vehicle motion along a guide track. The ride includes a vehicle chassis that engages the guide track and travels along the ride path during operation of the ride. The ride further includes a cam-based positioning assembly that is supported by the vehicle chassis to move with it along the guide track. The positioning assembly operates in response to being moved along the guide track to rotate the passenger compartment. The positioning assembly rotates the passenger compartment in counterclockwise and clockwise directions to provide 360-degree rotation. The positioning assembly includes a cam shaft with three cam follower pairs offset along the shaft and extending outward from the shaft at angular offsets, and three cam rails are used to selectively position the followers to rotate the cam shaft and set the position of the passenger compartment.

  • Patent number: 8179337
    Abstract: One particular implementation of the present invention may take the form of a mobile set configured to include one or more projection devices to display a media presentation to a viewer. The mobile set may be configured to follow a fixed path or may move through autonomous navigation. In one embodiment, the mobile set may be included as part of an amusement park ride to interact with the ride patrons and provide them with a greater entertainment experience. For example, the mobile projected set may be synchronized to move with a carrier vehicle carrying the ride patrons and project a presentation or display to the ride patrons during the ride. Placing the projected scene on a mobile set allows the patrons to interact with the projected scene for a longer period of time then if the projected scene was stationary. Further, the mobile sets may be used to configure and control sightlines through the ride to provide a more dynamic environment for the amusement park ride.

  • Publication number: 20120088592
    Abstract: A rotating hub ride configured to position passenger vehicles at different vehicle radii relative to the hub's axis of rotation. The ride includes curved support arms extending outward from the hub, with a first end coupled to the hub at a lower height than a second end of the arm. A vehicle is attached, via a mounting assembly, to each curved support arm to slide radially inward and outward on the arm in response to forces applied to the vehicle due to rotation of the hub, e.g., at two or more hub rotation rates. The arm or track defines a travel path for radial movement of the vehicle. When hub rotation is halted, the vehicle slides inward on the track to a load position corresponding to a minimum vehicle radius. At increasing hub speeds, the vehicle slides outward to position the vehicle in any of a number of vehicle radii.

  • Patent number: 8147344
    Abstract: A ride system for moving a passenger vehicle through a dynamically-defined work space. The system includes a track structure that guides one or more motorized or driven carriers on the track structure. The system includes winches on the carrier(s) that are independently operable to set lengths of the vehicle supporting cables, which extend outward from the winches to the vehicle. During operation, the winch systems provide upper anchor points for suspending the passenger vehicle such that these anchor points are selectively positioned. The winches may be independently operated as the carrier(s) travels from a first position to a second position, such that the vehicle body pitches, rolls, or yaws and moves transversely relative to the track. The winches may be operated concurrently to drop or raise the vehicle to define the work space for the vehicle in the vertical direction. Passenger input may interactively control motion of the vehicle.

  • Patent number: 8117968
    Abstract: A magnetic pacer system and method for adjusting vehicle speed in an amusement park ride. The system includes a controller and memory that stores speed settings such as upper and lower speed limits for the vehicle in a specific portion of a ride. A magnetic thruster is positioned near the portion of the ride, and a signal or signals are sent from position sensors to the controller. The controller determines the actual velocity of the vehicle as it travels along a direction of travel and acts to compare the determined vehicle velocity with the stored and desired speed settings. The controller then determines a magnetic force to apply to the vehicle including selecting whether the force is along the direction of travel or opposite to provide acceleration or deceleration of the vehicle. The magnetic thruster is selectively operated to generate a magnetic force to act on the vehicle.

  • Publication number: 20120040766
    Abstract: A round ride with passenger-initiated motion profiles controlling vertical vehicle movements. The ride includes a drive assembly with a rotating hub that includes support arms extending outward from the structure supporting passenger vehicles. Each of the vehicles includes a triggering device capable of generating either an onboard or offboard discrete signal when operated by a passenger causing a controller to select a motion profile from a number of stored profiles that each defines an actuator motion profile (or angular movement of a support arm about its pivotal mounting point to the rotatable central hub). The motion profiles define different angular rotations for a support arm to cause a vehicle to jump to differing heights, and the profile may be chosen by the controller based on vehicle height and position along the circular path and other environmental inputs such as a game state for the vehicle or a show/ride status.
