20080297328TACTILE FEEDBACK MECHANISM USING MAGNETS TO PROVIDE TRIGGER OR RELEASE SENSATIONS - An apparatus for providing tactile feedback to an operator. The apparatus includes first and second magnetic assemblies having first and second magnets, respectively. The apparatus further includes a user input device, such as a trigger, a knob, a release cord, or a joystick, that is connected to at least one of the two assemblies and positions the first magnet proximate to the second magnet such that interaction occurs between the magnetic fields to generate a force that is exerted on the input device. The force may be an opposing, resisting, or attractive force that creates movement of the user input such as resisting a triggering or releasing action in an interactive video game when the poles are of like polarity. The first magnetic assembly may be stationary, and the second magnetic assembly may be connected to the user input device to be positioned relative to the first magnet assembly.12-04-2008
20090114114MAGNETIC PACER FOR CONTROLLING SPEEDS IN AMUSEMENT PARK RIDES - 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.05-07-2009
20090209357AMUSEMENT PARK RIDE PROVIDING FREE-FLYING EXPERIENCE - A vehicle for simulating flight in a park ride having a rotating drive with supports or radial arms. The vehicle includes a body with seats and passenger restraints. A connection assembly is used to attach the body to a support. The connection assembly includes a linkage assembly allowing the body to radially pivot inward and outward relative to the drive assembly based on the angle of the support arm and rotation rate of the drive assembly. The linkage assembly translates radial movement of the body into rotation of the body about a pitch axis. The pitch axis extends through or proximal to the center of mass of the body, and the pivotal connector that supports the vehicle in a pendular manner is spaced apart and above the center of mass. The linkage assembly may include one or more four-bar linkages to provide two degrees of freedom of the body relative.08-20-2009
20090266266CABLE TOW WHIP RIDE WITH INSIDE CURVES - A whip ride is provided for amusement parks. A platform is provided with a guide slot extending through the platform.

A passenger whip vehicle is provided on the platform upper surface and pivotably attached via a connector extending through the guide slot to the bogie. The bogie path includes inside and outside curves, and the bogie track is vertically offset from the drive member such that its path may crossover the drive member to vary the horizontal offset and to locate the bogie track on either side of the drive member.10-29-2009
20090269175VEHICLE TRANSFER DURING OPERATION OF AN OMNIMOVER RIDE - An assembly for transferring passenger-carrying vehicles to and from an amusement park ride conveying a train of vehicles without stopping for passenger loading. The assembly includes a transfer vehicle and a vehicle receiver positioned in the vehicle train. The vehicle receiver includes a connection mechanism, such as an electromagnet selectively operable to capture and release the transfer vehicle. A turntable is positioned adjacent to the track and selectively rotates at a rotation rate. The turntable includes an engagement mechanism, such as an electromagnet, on its periphery operable to capture and release the transfer vehicle (e.g., to capture when the vehicle receiver releases and vice versa). The rotation rate and the ride speed synchronize turntable rotation with travel of the train to mesh placement of the turntable engagement mechanism proximate to the connection mechanism of the vehicle receiver to facilitate hand off of the transfer vehicle without stopping the vehicle train.10-29-2009

The vehicle assembly includes a water release mechanism that is passenger operable to release water from the vehicle as it is moved through the ride path. The vehicle body may include a water storage reservoir storing a volume of water that then can be selectively released by the passenger. The stored water may be caught as it pours over the vehicle or the vehicle may pass through a pool to scoop up the water.01-14-2010
20100053029MOBILE PROJECTED SETS - 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.03-04-2010
