Title: Theme park ride with ride-through screen system

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates, in general, to theme or amusement park rides with video or projected images, and, more particularly, to ride designs that use vehicles to move passengers through a themed attraction or ride with show portions and that use doors or other devices to separate and/or isolate various segments of the ride or show (e.g., to block light and/or sound from traveling along a track with the passenger vehicles or to prevent or minimize mixing of ride or show segments). 
     2. Relevant Background 
     Millions of people visit amusement parks each year, and park operators seek rides to attract new and returning visitors to their parks including rides that make their parks unique compared with their competitors&#39; parks. In theme and other amusement parks, most attractions utilize vehicles even when the attraction is a walk-through or slower ride because vehicles or people movers are useful for delivering entertainment to large numbers of guests (e.g., some rides have theoretical capacities of hundreds and even thousands of guests per hour) and maintain throughput or flow of the guests or passengers through the rides. Many rides include a slower portion or segment to allow them to easily provide a “show” in which animation, movies, three-dimensional (3D) effects and displays, audio, and other effects are presented in a carefully timed or synchronized manner to vehicles proceeding through such show portions. The show portions of rides are often run or started upon sensing the presence of a vehicle and are typically designed to be most effective when vehicles travel through the show portion at a particular speed such as several feet per second (or a typical walking pace or somewhat faster or slower). 
     In a typical show or theme ride, guests or passengers may walk into and through a pre-show area (e.g., a queue or waiting area) in which video or other effects such as animatronics are used to introduce the story or show to be provided during the ride. The guests then enter a loading area where they are loaded into a series of vehicles or people movers. The vehicles, which may be attached to a drive chain or cable, are moved along a track that is divided up into a number of show segments or portions. Some rides include video effects such as three-dimensional (3D) videos, and images are projected upon screens that are typically positioned along the walls or ceilings near the moving vehicles. To provide better viewing of these displayed images, the vehicles may be complex and costly such as vehicles with many moving parts and degree of freedom (DOF) motors to rotate the vehicle to view screens to the left or to the right of the moving vehicle. Vehicles may also include doors, roofs, and/or windows to direct the guests to view in a particular direction or to provide limited, directed line of sight toward show aspects. The projected images are preferably closely synchronized to the location and rate of travel of the vehicles, and this may require numerous sensors to determine the location of the vehicles and controllers to precisely start and stop projection of images based on sensed vehicle locations. For rides with 3D projected video, the passengers may also be given 3D glasses to wear. The show effects may also include animatronics and a set to add to the 3D effect or realism of displayed images. 
     It is typically desirable to separate the various show segments or portions to isolate the audio and lights associated with each segment to a particular length of the track, e.g., such that passengers can only see one show segment at a time. Rides may be configured to provide show segmentation and isolation by providing a circuitous path for the track with differing show segments provided in different “rooms” or along various lengths of track that may be separated by a bend or two in the track. Such an open track design may not prevent sounds and lights from traveling between these “rooms” or sections of the track especially in particularly loud shows or ones with bright lighting effects or displays. The bleed over or mixing of show segments may ruin the show effect for lead or trail vehicles or at least detract from the overall ride enjoyment for some of the guests. 
     To better isolate various show segments, the ride design may include doors or other barriers between neighboring show segments. For example, a door (e.g., a show action door) may be provided in a show tunnel that is operated to open to allow a series of vehicles to move from one show segment or room to another and then operated to close. The door may be a two-part door with each side or half hung on hinges and moved or swung open with hydraulic devices in response to a sensor detecting an approaching vehicle. The show action doors are desirable within the attraction for defining and isolating the individual scenes and for controlling light and sound. Unfortunately, these action doors may be expensive to design, install, and maintain due to the mechanical drive systems and electronic and optical sensors and/or control elements. Further and in some cases more importantly, existing show action doors are often undesirable because opening and closing them can be too loud, e.g., the hydraulic actuators used to open and close the doors typically generate noises that are heard by passengers in the vehicles that may distract the passengers from the show features and these noises are difficult to mask. 
     Hence, there remains a need for theme ride designs that provide effective ways to separate one show or ride segment from another and that support display of video images. Preferably, such ride designs would provide a very quiet way of isolating the show segments to limit distractions that may effect a passenger&#39;s or guest&#39;s enjoyment of a theme ride or ride with a show portion. 
     SUMMARY OF THE INVENTION 
     The present invention addresses the above problems by providing vehicle and screen assemblies that are adapted to provide touch free (or no contact) ride-through screen experiences in theme or amusement park rides. In this regard, a “screen” is considered any movable or pivotable show or scenic element that may be positioned in a vehicle&#39;s path. To this end, a vehicle may be equipped with a number of levitation rails that extend over a curved exterior surface of a vehicle. Each of these rails may be used to house a plurality of permanent magnets with like poles oriented outward or toward an exterior surface of the rail. A screen, door, animatronic figure, or other scenic element may be placed across or orthogonal to a track traveled or followed by the vehicle, and the screen may be segmented or include a number of segments similar to triangular wedges of a pie, be a side-by-side door arrangement, be a single mural or projector screen, or the like. Each screen segment is mounted with a hinge or other pivoting mount on a side of the body (e.g., triangle&#39;s base, rectangular door&#39;s edge, or the like). To provide magnetic levitation, one or more permanent magnets is placed in the tip of the segment body with a like pole as those in an aligned or corresponding levitation rail on the vehicle. Hence, as the vehicle passes through the closed screen, the screen segments are levitated away from the levitation rails by mutually repulsive or repelling magnetic forces, with the shape and length of the levitation rail or series of magnets being chosen to trace or approximate the swing or travel path of the magnets in the tips/edges of the screen segments as the segments rotate about their bases or mounted edges. In this manner, embodiments of the invention provide a screen actuating vehicle along with a passive screen in a ride path that may be used for displaying projected images as well as providing sound and light control to better define portions of a themed ride or attraction. 
     More particularly, an assembly is provided for use with a vehicle track of a ride system in a theme or amusement park to create a ride-through screen experience. The assembly includes a vehicle for carrying passengers that has a base adapted for mating with or riding on the vehicle track and, typically, for seating the passengers. The vehicle also includes a top or roof assembly with first and second sets of magnetic elements on an exterior surface of the top assembly, with each of the sets having a like pole oriented outward from the exterior surface. The assembly further includes a screen assembly with first and second screen segments (e.g., planar fabric sheets or the like that are pivotably mounted adjacent to each otherThe so as to hang or be positioned in a closed position for the screen assembly) that are transverse or, in some cases, orthogonal to the vehicle track. The first and second screen segments each include a magnetic element with an exposed pole that matches the outward facing pole of the corresponding or paired one of the sets of magnetic elements on the vehicle. During operation, the first and second screen segments are magnetically levitated away from the top assembly when the vehicle passes through the screen assembly on the ride track without the segments touching the vehicle. 
     The magnetic elements of each set may be permanent magnets that are arranged along a length of a levitation rail that is provided in the top assembly. The screen segments may have a body with a triangular shape (such as an isosceles triangle), and the magnet elements of the screen segments are provided in a tip that is distal to a base side of the triangular body. The levitation rails may then have a curved geometry or shape that is selected based on or to trace a swing or travel path followed by the corresponding one of the screen segment magnetic elements as the screen segment is rotated about the pivotable or hinged mount, e.g., about the base of the triangular body. The body may be formed of a material(s) to provide a projection surface for displaying a video image projected from one or more projectors. The screen assembly may also include third and fourth screen segments mounted adjacent the first and second segments, with these two segments also being triangular in shape and including a magnetic element in or near their tips. In this case, the vehicle will typically include third and fourth levitation rails that are arranged to be aligned (and their housed magnets) with the magnetic elements of one of the screen segments. 
     For example, the magnetic elements may be a plurality of permanent magnets (such as rare earth magnets) aligned within about 0.25 inches of the swing path of the corresponding screen segment magnets that are linearly arranged with a spacing between neighboring magnets of less than about 0.125 inches. The top assembly may include a flexible cover that extends between at least two of the levitation rails and one or more of the levitation rails may be positionable (e.g., rotated about its mounting points or the like) in a closed position and in an open position in which passengers may enter and exit the vehicle. The screen segments may close or return to the original or transverse plane passively under forces of gravity and/or return mechanisms may be provided as part of or separately to the mounting assembly to apply a force to the body of the screen segments to return them to the original position across the vehicle track or vehicle travel path.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Briefly, embodiments of the present invention are directed to systems, and associated methods, for theme or amusement park rides that provide a ride with show portions and a drive or ride-through screen. In some embodiments, the ride-through screen is also used as a projection screen such as for a video projection surface. The ride-through screen may be segmented with each segment rotating about its base or mounting end and including an actuator member at its tip (e.g., at its point when the segments are triangular in shape). The ride also includes a vehicle that is configured to actuate and/or move the ride-through screen (e.g., the vehicle and screen make up a vehicle/screen assembly of the invention). The vehicle is driven by a drive system such as a cable or chain drive or other useful drive arrangement for rides along a track that causes the vehicle to pass through a frame supporting the screen segments such as on hinges or similar mounts. 
     In one preferred embodiment, magnetic levitation is used such that the vehicle passes through the screen without contact (i.e., touch free) with screen segments. In this embodiment, the vehicle includes a top, cover, or roof with two or more levitation rail assemblies. Each such assembly includes an elongate, curved (or arcuate) rail extending over the vehicle top, which also is typically curved in shape (e.g., generally elliptical or spherical in shape or, in some cases, the vehicle body may be relatively egg-shaped with a shorter, wider base and a longer, more pointed front end corresponding to the trailing and leading ends of the vehicle while other cases may have a spherical vehicle body). The rail includes a groove or recessed surface along its length for receiving a series of magnets such as strong permanent magnets that are disk or circular in shape, are bar shaped, or other shapes, with each of the magnets being arranged with a same or like pole directed upward or outward from the rail (e.g., north or south poles facing out of the recessed surface). 
     In this embodiment, each of the segments of the screen includes at least one magnet near the tip or an edge (or an exposed portion) with the pole selected such that as the vehicle&#39;s rail approaches the screen magnetic repulsion of the screen magnets by the rail magnets causes the screen segments to be actuated (e.g., the magnet in the screen tip or edge acts as the actuator member of the tip or edge) or to be levitated away from the passing vehicle. The number of rails is selected to match the number of screen segments, and the location and shape of the rails is selected to align the series of magnets in the rail with the magnet(s) in the tip or edge at least at initial contact but more typically along the entire length of the rail or vehicle body so as to cause the screen segments to float over the top of the vehicle&#39;s outer surface. In other embodiments, the actuator member in the segment tip or edge/side is a roller that contacts the rail surface and rolls along the vehicle roof as the vehicle passes through to the next room or portion of the ride. After the vehicle passes through, the screen segments are returned to a closed position (e.g., each segment may be mounted on hinges and may return to a closed position due to the forces of gravity and/or counterweights may be provided to assist gravity (or for more horizontally mounted segments)), and, in the case of magnetic actuator members, the tips or edges of the screens/doors may be held together or in proximity (at least with a small amount of force) by the magnetic fields of the adjacent magnets. 
       FIG. 1  illustrates a ride system  100  of an embodiment of the present invention that includes a vehicle and screen assembly  130  that is uniquely adapted to provide a ride-through screen effect or operation mode. The inventor understands that in theme and amusement parks that the people mover or ride vehicle remains an important tool for delivering entertainment rapidly to many guests. To this end, the ride system  100  includes a vehicle or car  132  with a base  134  riding on wheels or casters  136 , and the vehicle  132  is adapted for receiving or carrying 1, 2, or more passengers or guests in the ride system  100 . Also, it is desirable in many attractions or themed rides with show elements to provide show action doors to define individual scenes, to control lighting and sound, and to present a scenic imagery. To this end, the ride system  100  includes one or more screen assembly (or show action door assembly)  150  that separates a first scene or room  110  of the ride system  100  (or a tunnel) from a second scene or room  160 . 
     The vehicle and screen assembly  130  may be thought of as combining the separate functions of a people mover and show action door into a single assembly or system with a master and slave relationship. The ride vehicle  132  is a dual-purpose component that provides show delivery (e.g., moving people through or to a show in ride system  100 ) and also provides show activating. Regarding the show activating function, the vehicle  132  functions itself to actuate or move the screen  150  rather than requiring the ride system  100  to include a number of vehicle sensors that are used to trigger noisy hydraulic actuators to operate a show action door. The screen assembly  150  is a passive component of the assembly  130  and is typically provided in relatively simple form (e.g., screen material mounted to rotate about hinged mounts or the like), which eliminates much of the mechanics and controls to reduce fabrication and maintenance costs. In some cases, the fabrication and operating costs of such a passive screen  150  are low enough that the ride may include many of such screens within one attraction or ride system  100 , which allows the screens  150  themselves to be incorporated into the show to become a featured element to entertain the passengers of the vehicle  132 . 
     As shown, the ride system  100  is adapted for a theme-type ride in which various show scenes or portions are provided in a series of rooms  110 ,  160 . The ride system  100  may include a show wall  107  (e.g., a tunnel defined by two sidewalls and a ceiling/roof) extending along (and around in some cases) a ride track  120  that may include one or more rails or other components used to guide a vehicle  132  along a path through the ride system  100 . A show including video and audio and other display components may be provided in the ride system  100 . For example, as shown, a projection screen or surface  109  may be provided on the wall  107  of room  110  and video projection equipment  111  may be activated to display a scene or portion of a show to the vehicle  132  (e.g., in response to sensing of the location of the vehicle  132  within the room  110  by sensors  113 ). The show may also include audio from speakers and/or other audio equipment  115 , and, of course, nearly any display devices such as high definition displays may be used for display screen  109  and projection device  111  (which may, instead, be incorporated in device  109  such as in a rear projection device, in a crystal display, or other device). 
     In some embodiments, the ride-through screen assembly  150  is also used as a video screen or display. As shown, the assembly  150  may include a frame (or mounting structure)  152  that supports and positions two or more screen segments  156  to separate room  110  from adjacent or neighboring room  160  defined by wall or tunnel  107 . Specifically, the screen segments  156  are positioned or hung such that they are blocking or across/transverse to the path of the vehicle  132  in the ride assembly  100 . In other words, the screen segments  156  are arranged transverse (and, in some cases, orthogonal) to the track  120  followed by the vehicle  132 . A projector or projection assembly  117  may be provided to display video or still images upon the screen segments  156 . Typically, the displayed images on segments  156  will be tied to the show provided on screen  109  and within room  110  and may even disguise the opening to the next room  160  (e.g., to increase a dark ride effect such as an illusion of danger of a crash, of travel through an environment such as a thick jungle, or the like). 
     The vehicle  132  generally includes a base or body  134  with wheels/casters  136  and is driven at a velocity, V CAR , along the track  120  by a drive  124  such as a drive cable or chain moving at a velocity, V CABLE , as shown at  125  and attached to the vehicle body  134  via linkage  126  extending up through slot or guide groove  122 . Typically, these two velocities would be substantially the same and in many theme or show portions of a ride system  100  may be relatively small in magnitude (such as less than 10 feet per second and often less than about 5 feet per second), but vehicle velocity, V CAR , is generally not a limiting feature of the invention with the vehicle and screen assembly  130  being adapted in some embodiments for much higher speeds (e.g., the screen  150  can be actuated at high speeds by the vehicle  132 ). 
     An important concept of the ride system  100  is that the vehicle  132  is used to actuate or move the screen  150  to allow the vehicle  132  to pass from the first room  110  to the second room  160 . In the illustrated embodiment  100 , this is achieved by providing the screen  150  with a number of screen segments  156  that may move independently from each other such as about a rotatable or hinged edge connected to the frame or support structure  152 . The vehicle  132  includes a cover or roof  140  that is adapted to actuate or move the segments  156 . In some embodiments, this may be achieved by providing rollers on one of the roof  140  and the segments  156  such that the segments  156  roll over the outer surfaces of the vehicle cover or roof  140  (such as a roller provided at or near the tip or side/edge of each segment  156  that rides on a track or rail  144  of the roof  140 ). The screen segments  156  may then return to their original positions using their own weight (e.g., gravity based return that may be useful for at least partially vertically hanging segments  156 ) and/or using a forced return or force-assisted return to a closed or original position such as may be achieved with springs or other resilient members provided on the mounting assembly and/or by use of counterweights on the mounting assembly, which may be useful for segments  156  that are horizontally mounted and cannot rely on gravity and their own weight to return to a closed position. 
     In one preferred embodiment, the vehicle and screen assembly  130  are adapted to make use of magnetic levitation or magnetic repulsion to provide a touch free or no contact ride-through screen experience. In this embodiment, the ride vehicle  132  is designed or modified to include a set of rails  144  that are arranged on the cover  140  to align with the sweep of the individual screen segments  156 . Typically, there are at least as many rails  144  as there are segments  156  in the screen assembly  150  (or like numbers in most cases) and each rail has an outward facing, line array of permanent magnets. In each rail, the magnets all have the same magnetic pole (e.g., N or S) facing outward from an outer (or exposed “contact”) surface of the rail  144 . The screen  150  is segmented into triangular segments  156  in one embodiment to provide one useful structure and function for a screen  150  that may be closed together to separate room  110  from room  160 , to receive a projected image from projector  117 , and also to easily separate along its seams (or dividing/neighboring edges). 
     Each segment may be hinged or otherwise mounted on its outside edge (e.g., edge near the structure or frame  152 ), and, in some embodiments, its hinged geometry is centered and perpendicular to a corresponding or paired rail on the vehicle (e.g., a line extending from a tip of the triangular segment  156  from a proximate “contact” or exterior surface of the rail or array of magnets may be orthogonal to a base edge or side of the segment that is next to the frame  152  and may also bisect this edge or side to provide desired centering or alignment of the segment  156  with the rail  144 ). Each screen segment  156  may have on its tip a permanent magnet of the same pole as the magnets arrayed on a matching one of the rails  144  (e.g., a rail with N poles facing outward would be paired with a segment tip having a magnet with its N pole oriented toward the oncoming vehicle  132  such as with the magnetic field generally parallel to the direction of travel of the vehicle or the track  120 ). As the vehicle  132  moves into or proximate to a plane of the screen segments  156 , the screen segments  156  are levitated away from the roof  140  by the mutually repelling magnetic forces. 
     The screen-actuating vehicle  132  passes through the screen  150  without contact as the segments are maintained by the magnetic repulsion at a distance (e.g., 1/32 to ½ inch or more) that will vary in magnitude based on the power of the magnets utilized in the rails  144  and tips of segments  156  and other design parameters such as weight of screens  156 , resistance of hinge or other mounting assemblies, speed, V CAR , of the vehicle  132 , and the like. In some embodiments, the vehicle and screen assembly  130  is configured for the vehicle  132  to pass through in one direction and, in other embodiments, the vehicle  132  may actuate the screen  150  in both directions which may require a second magnet(s) to be provided on the tip of segments  156 , to have the hinged attachment operate in both directions, and to have the rail be designed for mating with and levitating the segment  156  with the tip magnet in either direction (e.g., a symmetric arrangement or the like). Further, the roof  140  and the rails  144  are adapted to allow guests to enter and exit the vehicle  132  such as by having the roof  140  open or by having at least some of the rails articulate (e.g., rails  144  on one side may be pivoted about end mounts to allow passengers to enter and exit a vehicle  132 ). 
       FIGS. 1 to 3  illustrate the ride system  100  during operation to provide a themed ride or an attraction with a show provided with a ride-through screen. As shown in  FIG. 1 , the vehicle  132  is located in room  110  where its passengers experience a show (e.g., screen  109  and projector  111  and audio system  115 ) as it travels at a ride speed, V CAR . The show may also include images (and associated audio) provided on screen segments  156  via projection or display assembly  117 , with the screen segments  156  being transverse or, in some cases, in a plane that is orthogonal to the direction of travel of the vehicle  132 . The screen segments  156  are formed of a material (such as a colored or white cloth/fabric, a white or colored seamless paper, textile backed (or supported) projection screen surfaces such as glass beaded, silver matte, or the like, an unsupported vinyl projection screen material such as Pearlescent™ or the like, or many other materials with or without a backing layer) that is useful for displaying images and also for blocking video and, in some cases, sound from traveling to or from neighboring or adjacent room  160 . 
     In the shown embodiment of assembly  130 , the screen  150  includes four relatively equally sized segments  156  (e.g., isosceles triangular shapes), and the vehicle  132  includes four arcuate or curved rails  144  extending across the exterior surface of the roof or cover  140  so as to be proximate to the tips of the segments  156  when the vehicle  132  passes through the screen  150 . Of course, the screen  150  may include fewer segments such as one large screen but more typically two or three segments or more such as 5, 6, or more are included, and the vehicle  132  would be configured with at least a matching number of rails or series of magnets (e.g., the magnets may be provided on the roof  140  or vehicle without use of a rail in some embodiments such as by attaching the magnets directly to the roof outer surface in a pattern to provide desired alignment with the tips of segments  156  and any included magnets). 
       FIG. 2  illustrates the ride system  100  in a transition stage or mode in which the vehicle  132  is driving or riding through the screen  150  from one room  110  (or show scene) into a second room  160  (or show scene). As shown, the vehicle  132  has entered the plane of the screen segments  156 , and, in some embodiments, the roof  140  or its exterior surface or rails  144  is used to contact and actuate or move the segments  156  such as about their hinge-mounted bases or edges near the frame  152 . In magnetic levitation embodiments, though, the rails  144  include a series of like pole magnets that actuate the segments  156  by repelling a magnet(s) in the tips of these segments with mutually repulsive magnetic forces. The length and number of the magnets in the rails  144  (or otherwise provided on the vehicle  132 ) are such that the vehicle  132  may pass or ride through the screen  150  with no contact of the screens (or, in some embodiments, contact is allowed for a trailing edge of the vehicle such as after the portion of the vehicle including the passengers or their viewing windows or line of sight has passed through the screen segments  156 ). As shown, each of the segments  156  is separated along its side(s) from adjacent or neighboring ones of the segments  156  and is rotating about its base or mounted edge as shown with arrows  210 ,  212 . The show may continue in its entirety or in part during this transition (e.g., the vehicle  132  may drive into a screen  150  that is active or being used to display images such as from projector  117  or a rear projector device or the like) or the show of room  110  may be phased out or turned off as the vehicle contacts or approaches the screen  150 . 
       FIG. 3  illustrates the ride system  100  after the vehicle  132  has passed through the room-dividing screen assembly  150 . As shown, the first show has been ended because there is no vehicle present, but it may be started when a next vehicle is sensed by sensor  113  and such a next vehicle may closely follow vehicle  132 . The screen  150  is shown returned to a closed or original position with the screen segments  156  in a lowered position with their tips close and side edges close together to provide a relatively solid projection screen. Again, the returning to the closed position may be achieved with gravity because the segments  156  may be mounted with the closed position as the neutral or at rest position, e.g., when an outside force such as the repulsive forces between the tip and vehicle magnets is not present, the screen segments  156  tend to return to this closed position. In some cases, additional closing components are provided such as a spring-type hinge or a counterweight assembly to force the segments  156  to return to the closed position shown in  FIGS. 1 and 3 . The magnets provided in the tips of segments  156  may be arranged or mounted such that their magnetic forces act to attract the adjacent magnets and corresponding tips so as to use attracting magnetic forces to hold the tips in the closed position (e.g., until a next vehicle  132  passed through the screen  150 ). As shown in  FIG. 3 , a show scene or portion may be provided to the vehicle  132  in the second room  160  such as with additional video and audio projection/display devices and another screen assembly may be provided similar to that of screen  150  to separate the room  160  from a next room (not shown). 
       FIGS. 4-9  illustrate a screen assembly  400  and a ride vehicle  600  that may be used together to provide a vehicle and screen assembly of an embodiment of the present invention that uses magnetic levitation to provide a no contact, ride through screen.  FIG. 4  illustrates a front view (or vehicle side) of a ride-through screen assembly  400 . As shown, the screen assembly  400  includes a frame  410  made up of a number of structural members  412 , which may be free standing to encompass a vehicle track assembly  470  upon which a vehicle may ride and/or be attached to a ceiling and/or sidewalls of a ride tunnel or passageway (not shown in  FIG. 4 ). The top members  412  may be symmetric about a center of the frame  410  and be provided at an angle, θ, to horizontal such as 15 to 60 degrees such as to descend at about 45 degrees from horizontal to meet vertical side members  412  of frame  410 . 
     The screen assembly  400  includes four screen segments shown by adjacent representative segments  420 ,  424  that meet at seam  422  when the assembly  400  is in an at rest or closed position as shown. The four segments are shown to be of equal size and shape in this embodiment  400 , although this is not required to practice the invention, and, more specifically, are shown to be triangular in shape (e.g., an isosceles triangle with a tip angle, β, such as up to about 75 degrees but more typically a smaller value in the range of 30 to 60 degrees is used). A magnetic element  428 ,  429  is provided at or near the extreme end of the tip of each element  420 ,  424  and assists in maintaining the segments in a closed or mating position  450  of the assembly  400 . Typically, the magnetic elements  428 ,  429  are permanent magnets with similar poles directed toward an oncoming vehicle on track assembly  470 . Each segment  420 ,  424  also includes a projection surface  421 ,  425  which may be a side of the body of segments  420 ,  424  that is adapted particularly for displaying an image that is projected upon the assembly  400 . An optional open area or space  460  is provided at the bottom of the screen assembly  400  to facilitate the track  470  passing through the screen assembly  400 , but, in other embodiments, segments may extend into space  460 , e.g., with pivotable or hinged edges provided adjacent the tracks  470  and mounted to the floor such as one on either side of tracks or guide rails for the ride system. 
     Segment  430  is shown in more detail to better explain one useful configuration for the screen assembly  400 . Segment  430  includes a body  431  that is configured as an isosceles triangle, and a projection surface  432  is provided on the body  431  and positioned to face a vehicle on track  470 . The body  431  may be fabricated from a lightweight cloth or fabric with a surface texture and/or configuration adapted to achieve a desired visual effect, e.g., to suit the projected video from a display device and/or to suit the scene or show effect provided in the room containing the screen  400 . Since a lightweight fabric may be used for body  431 , side cables (or rigidity elements that may be formed of wire or the like)  434  and  435  may be provided on each side to allow the fabric of body  431  to be kept in the triangular shape and/or to allow the fabric to be stretched to a desired tightness (e.g., to make the surface  432  substantially planar and the edges sharp or well defined on sides near side cables  434 ,  435 ). The side cables  434 ,  435  may extend the length of the sides to the tip  447  where they may be joined or simply terminate. At the other end, the side cables  434 ,  435  may be linked to a base member  438  such as a rod, bar, or the like that extends along the base of the triangular body  431  and the fabric of the body  431  may be attached to this base member  438 . To allow the body  431  to pivot or rotate about its base, the base member  438  may be attached to a hinge or pivotable mounting device  440 , which is affixed to the frame member  412  (such as on the back side as shown in  FIG. 5 ). 
     A magnet element  446  such as a permanent bar or disk magnet (e.g., a powerful rare earth magnet or the like) is provided at or proximate to the tip  447  and centrally positioned to provide alignment with the other magnets in tips of other segments and with a corresponding series of actuating or levitating magnets on a vehicle. The magnet  446  may be positioned with a pole face in a plane that is perpendicular to a plane containing the track  470  as it passes through screen  400 . In other embodiments, the magnet  446  is provided at an angle such as 0 to 45 degrees from such an orthogonal plane so as to better direct a repelling magnetic field toward magnets on an approaching vehicle&#39;s cover or roof. To provide further rigidity and structure, a support member or arm  436  is provided that extends out from the base member to the tip  447  (e.g., a 0.25 to 1 inch or larger metal or plastic rod or bar that extends outward from a midpoint of base member  438  to bisect the angle, β, at the tip  447 ). 
       FIG. 5  illustrates a back or hidden side of the screen assembly  400  that shows hinged or pivotal mounting such as with hinge  440  for each of the screen segments with attachment to their base members such as member  438  to hinge  440 . Also shown is a counterweight assembly  510  that may be attached to the base member  438  to resist opening of the segment  430  but also assist in returning the segment  430  to the closed or original position as shown with arrows  512  near the counterweights. Instead of counterweights, the hinge  440  may include a spring or resilient member or such as a return element that may be attached to the body  431  (e.g., similar to a standard screen door closing assembly). Such motion-assist assemblies are particularly useful in side or horizontally mounted segments such as segment  430  that typically will not return to the closed position after being opened without such assistance (e.g., gravity alone typically cannot be used to close or return these segments to their original positions) after a vehicle passes through. Motorized or mechanisms that can be actuated such as based on a vehicle being passing a point on track  470  beyond the screen assembly  400  may be used on the side or horizontal segments, but such inclusion may complicate the assembly  400 , which is shown as a “passive” device, and add to fabrication and maintenance costs. 
       FIG. 6  illustrates a side view of a screen-actuating vehicle  600  of an embodiment of the invention that uses magnetic levitation to actuate the screen assembly  400  of  FIGS. 4 and 5 .  FIG. 7  shows the vehicle  600  from a front perspective view as it may appear as it approaches the screen  400  to ride through it. As shown, the vehicle  600  includes a base or body  610  with one or more seats  614  for seating for passenger(s)  616 . The body  610  includes a set of wheels, casters, or other components  612  that allow the vehicle  600  to be driven at a particular velocity, V CAR , along a track  470  that passes through screen assembly  400 . The vehicle  600  further includes a frame  630  extending upward from the body  610 , such as in an arc or curve to provide a structural support and/or to guide travel of a roof or retractable top assembly  620 . 
     The roof assembly  620  is attached to the body  610  at each end as shown by mounting elements  636 ,  637 . The frame  630  may provide supports at one or more points along the expanse or length of the top  620 . Significantly, the top  620  includes a set or number of actuation or levitation rail assemblies  622 ,  624 ,  710 ,  720  that extend along the length of and in spaced-apart fashion across the surface of the top  620  to function to actuate and/or move corresponding screen segments of screen  400  out of the path of the vehicle  600 . Each of these assemblies  622 ,  624 ,  710 ,  720  typically is configured similarly. 
     With reference, for example, to rail assembly  624 , the assembly  624  includes an elongate, arcuate or curved rail  628  that is pivotably mounted at its ends to mounting elements or pins  636 ,  637 . The rail  628  is used to support and align a series of magnets  626 , e.g., a plurality of permanent disk or bar magnets with like poles facing outward from the rail  628 . A cover strip  629  may optionally be provided over the magnets  626  to retain them in place in the rail  628  and/or to provide a protective and/or disguising cover (e.g., to heighten the illusion of how the screen segments are actuated or moved away from the approaching vehicle  600 ). 
       FIG. 8  illustrates a sectional view of the rail assembly  624 . In this embodiment, the rail  628  includes a recessed surface or groove in which the magnets  626  are received with an orientation that directs the N pole  804  of the magnets  626  facing outward from the rail  628  and with the S pole  808  facing inward (e.g., the series of magnets  626  in a rail assembly  624  have the same pole exposed for use in levitation or actuation of a corresponding screen segment). Adhesive  810  may be used to attach the magnets  626  to the rail  628  or in other cases the magnets  626  may be interference fit into the rails  628  or the cover  629  may be used to hold the magnets  626  in place in the assembly  624 . Other restraining techniques may be used, with such restraint typically being desirable to allow the magnets  626  to be positioned relatively near to each other without magnetic forces “popping” the magnets out from the rail  628 . For example, the magnets  626  may be disk or circular magnets with a particular diameter, D MAGNET  (such as 0.25 to 1 inch or larger magnets) and a particular thickness, t MAG  (such as up to 3/16 inches to ½ inch or more thick), and to maintain a relatively uniform levitation magnetic force along the length of the rail  628  it may be desired to abut or nearly abut these magnets  626 . For example, when circular magnets are used the repulsive forces between adjacent magnets and their other characteristics may require a small space between neighboring or adjacent magnets  626  such as up to about 0.125 inches or more (with closer typically preferred). In other embodiments, the magnets  626  are block or rectangular magnets, and these may be placed in abutting contact in some cases along the rail  628 . The cover strip  629  is typically formed of a non-magnetic material and is relatively thin to place the surface of the magnet  626  near the exterior “contact” surface of the rail assembly  624 . 
     Referring again to  FIGS. 6 and 7 , the rail assemblies  622 ,  710 , and  720  typically would be configured similarly to rail assembly  624 , and  FIG. 7  shows that assembly  710  includes an elongate, arcuate rail  712 , with a groove including a plurality of magnets  716  extending along the length of the rail  712 , and a cover plate or strip  714  over these magnets  716 . In the illustrated embodiment, the top assembly  620  further includes a screen or sheet  634  extending over or under the rail assemblies or between such assemblies, and it may function to enclose/define the interior of the vehicle  600  and may be formed of substantially see-through or a material/fabric that allows passengers  616  to view a show displayed outside of the vehicle  600 . Typically, the roof screen  634  is fabricated of a relatively flexible material that draws tight when the rail assemblies  622 ,  624 ,  710 ,  720  are in the closed position shown in  FIGS. 6 and 7 . 
     To allow passengers  614  to enter and exit the vehicle, one, two, or more of the rail assemblies (and the adjoining roof screen  634 ) typically are able to be articulated or moved. For example, as shown in  FIG. 9 , the vehicle  600  is shown with the top assembly  620  in the open position or mode of operation. To place the vehicle  600  into this open position, the rail assemblies  622 ,  624  are pivoted about end mounts  636 ,  637  to move along the curved inner support  630 , and the roof screen  634 , which may be a mesh material such as a dark screen material or net with small holes or gaps or the like, is compressed or accordioned together between the rails. 
     After the passenger(s)  614  are positioned into the vehicle  600 , the vehicle  600  is moved along the track  470  such as through a show portion or room where a video and audio show is presented, which may include displayed imagery on screen segments or display surfaces of screen assembly  400 . The vehicle  600  then transverses the screen plane containing the screen segments  420 ,  424 ,  430  until the rail assemblies  622 ,  624 ,  710 ,  720  initially are placed in proximity to tips of the screen segments and the magnets  428 ,  429 ,  446  contained therein. Note, there are at least as many rail assemblies as screen segments and an actuating rail assembly is aligned with or paired to each screen segment (e.g., with the rail assembly placed in proximity with the magnet of the screen segment). The magnets in each rail assembly generate a magnetic field with a like polarity as that found in the aligned, paired screen segment (e.g., both N poles or both S poles), and this creates a repelling or levitating magnetic force between the nearest one, two, or more magnets in the rail and the tip magnet(s). As a result, the tip and the corresponding screen segment are pushed away from the proximal magnet(s) of the rail, which are approaching the screen assembly  400  at the velocity, V CAR , of the vehicle  600 . 
     The rails are shaped such that as the vehicle travels through the screen each magnet in the series or set of levitation magnets in the rail is placed adjacent the tip magnet and repels the tip. The shape may be, as shown, a generally arcuate or elliptical shape or another shape/geometry to practice the invention with the shape depending upon the path traveled by the tip (or magnet in the tip) of the screen segment as it is rotated out of the path of the passing vehicle  600  (i.e., the invention is not limited to a particular rail shape as long as levitation is maintained as desired to provide touch free or, in some cases, a limited amount of contact such as after the passenger&#39;s or view portion of the vehicle  600  has passed the screen plane). 
     Some embodiments of the invention provide a vehicle and screen assembly in which the screen is actuated or moved by the vehicle, but the screen is actuated by physically contacting the exterior surface of the vehicle. For example, the vehicle may take a form similar to that shown in  FIGS. 1-9  but without the magnets and, in some cases, without the rails shown (such as when the roof has a rigid exterior rather than flexible screen or sheet on the retractable portion).  FIG. 10  illustrates a screen segment  1000  that may be used when magnetic levitation is not used and contact is allowed for actuation by the vehicle. The screen segment  100  includes a projection screen or body  1010  that is triangular in shape. A pair of edge rigidity elements  1014 ,  1016  are provided along with a central structural member  1012  (e.g., a bar, rod, or the like) that may be attached at the other end to a hinged base member (not shown). 
     At or near the tip  1013  of the segment  1000 , a roller assembly  1020  is provided that may be connected with a central base or hub member  1014  to the structural member  1012 . A pair of wheels, rollers, or casters  1026  may be pivotably attached (such as an axle(s)) to the hub member  1024 . During operation, the rollers  1026  contact an exterior surface of a passing vehicle, such as the rail assemblies or their cover strips/sheets shown for vehicle  600 . The roller  1026  typically stays in contact with the roof surface or rail as the screen segment  1000  (and others like it provided in a screen assembly) is actuated or pushed apart and around the passing vehicle. As with the screen assembly  400 , the screen segment  1000  would then be returned to its original or closed position such as by gravitational forces and/or with assistance by a spring hinge, counterweight, or other mechanism. 
     Although the invention has been described and illustrated with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example, and that numerous changes in the combination and arrangement of parts can be resorted to by those skilled in the art without departing from the spirit and scope of the invention, as hereinafter claimed. One aspect of the above description is that the vehicle itself is used to actuate a screen, which may be used as a projection screen or surface for a video show portion of a themed ride. The actuation may be mechanical or by touch/contact while many preferred embodiments utilize permanent magnets such as rare earth magnets (round or bar) to magnetically repel or levitate the screen segments. To this end, a series of magnets of a same pole are arranged (such as in a rail, on the exterior surface of the roof, in recessed surfaces provided in a molded, retractable roof, or the like) to match a travel or swing path of a magnet(s) located in the tip or other portion of a screen segment as the screen segment rotates or pivots from the travel path of the vehicle. In some illustrated embodiments, the shape or configuration of the magnets may be an arc or a portion of an arc such as when the vehicle is more spherical. In other cases, the shape is more elliptical while in other cases the configuration or shape of the series of magnets on the vehicle may be somewhat irregular (e.g., a combination of linear and curved sections). The number of magnets provided on the tip of the segment may vary to practice the invention, and some embodiments use two or more magnets arranged in a line or linearly that are utilized to provide a levitating (or repulsive) force to maintain the screen segment spaced apart (e.g., up to 0.5 or more inches) from the exterior surfaces of the vehicle. 
     In some cases, the alignment of the magnets (or their centers) is required to be relatively close or fine with the travel or swing path of the magnet in the segment tip or edge. Such close alignment is required because of the behavior of magnets and a desire to align or orient the relative magnetic fields of the vehicle actuation magnets and the actuated (or repelled) magnets in the screen segments. In other words, the magnetic fields of the like pole magnets may have to be nearly directly opposite to provide a mutually repulsive force rather than an undesirable attraction force (e.g., improper alignment may cause the segment to be attracted to contact or be attached to the vehicle roof). In some embodiments, the alignment along the length of the series of magnets or the rail containing the magnets in vehicles using rails is in the range of plus or minus 0.25 inches, but, of course, the alignment obtained or used will vary with the geometry and power of the magnets chosen for the vehicle and screen assembly. 
     The illustrated embodiments show screen assemblies that are used in a single direction. However, in some embodiments, the ride system may be designed such that the vehicle may travel in both directions on a track. In such embodiments, the vehicle may be configured to be symmetric with passengers facing both directions, and the series of actuating magnets or an actuation rail/track on the roof or exterior surface of the vehicle typically would be symmetric (e.g., with a similar shape on a front half and a back half of the vehicle body). In other cases, the vehicle may turn around at some point of the track and return along a same length of the track and pass through some rooms in both directions. In either of these cases, the screen assembly may be configured such that the screen segments may open in either direction based on a two directional hinge or pivotable mounting at their base or another edge/side. Further, one or more additional magnets (or other actuation devices) may be provided on the “back” side of the screen segments near their tips or edges (e.g., a magnet with a particular pole (i.e., a pole that is the same as that exposed or facing outward on the vehicle)) is provided on both sides of the screen segment. In this way, the vehicle may actuate the screen when traveling in either direction. In these embodiments, the screen segments may also be designed as projection surfaces on both sides. 
     Note, also, the screen segments are shown to contain one or more magnets at or near the tip of their triangular body or edge of their non-triangular door or panel shape. In some configurations of the vehicles and their series of levitation magnets, the segment or door magnets may be provided in other locations with a key aspect being that the (or one of the) first surfaces of the segment that is positioned proximate to the approaching vehicle contains a magnet (or a mechanical mechanism) used for levitating (or moving) the screen away from or around the vehicle as it passes through or near the plane containing the screen segments. 
     Note, the above description uses the term “screen” to generally mean a scenic element or object that is in the pathway of the vehicle (e.g., screening the path of a vehicle and/or view of riders of such vehicles). For example,  FIGS. 1-10  discuss a screen or scenic element that has segments that are triangular in shape, but the invention is not limited to such an arrangement for the “screen.” Also, these figures show an oblong or elliptically shaped vehicle(s) that is suited for such a segmented screen. In other embodiments, many other screen, door, or scenic elements/objects may be utilized to practice the invention such as a screen that is projected upon that is moved as a single unit or in segments as described, a mural or piece(s) of artwork, a “brick” or other structural appearing show element (e.g., appears as if the vehicle will crash into a solid wall that moves as a single unit or that is segmented as described as the vehicle “crashes” through it), or even a statue or an animatronic figure that is in the path of the vehicle. Each of these screens or scenic elements is actuated by the vehicle so as to be moved from the vehicle pathway in a touchless or contact manner. 
     For example,  FIGS. 11 and 12  illustrate a screen/door and vehicle pairing or assembly that may be used to practice the vehicle actuation functionality described herein. As shown in  FIG. 11 , the scenic element is a show door arrangement with a pair of side-by-side doors  1120 ,  1124  that are supported by a frame  1112 . The doors  1120 ,  1124  appear as more conventional rectangular doors and are hung or supported on end elements or sides  1142 ,  1143  and allowed to pivot about these ends/edges  1142 ,  1143  on hinges or pivot members  1440 ,  1441 . In the closed position shown, inner edges or sides  1121 ,  1125  of the doors  1120 ,  1124  are contacting or nearly in contact with each other to separate one show room or portion from another. Each door  1120 ,  1124  includes one or more magnetic elements  1128 ,  1129  (which may be replaced with rollers in some embodiments as discussed with reference to  FIG. 10 ). As a magnetic with like pole (e.g., on a moving vehicle shown in  FIG. 12 ) approaches the doors  1120 ,  1124 , the magnetic elements  1128 ,  1229  cause the doors  1120 ,  1124  to pivot about hinges  1140 ,  1141  out of the path of the object or vehicle supporting the like pole magnets. Counter weight devices or other components may be provided to cause the doors  1120 ,  1124  to return to the closed position shown in  FIG. 11  after being actuated or moved to an open position. 
     The doors  1120 ,  1124  (or screen or scenic element) may be supported on frame  1112  over a track as discussed for other embodiments of the invention. Alternatively, as shown, the doors  1120 ,  1124  are supported over a platform or floor  1170  that has no tracks. In this embodiment, the vehicle track is removed and the door or screen assembly of  FIG. 11  is intended for use with a trackless vehicle. In amusement and theme parks, rides and rides with show elements are being created with vehicles that have travel over a trackless floor and the vehicles position is typically tracked and may be controlled to travel along a predefined path (or portions are defined). Such vehicles may be considered free ranging vehicles with their travel on a path typically monitored/sensed to allow the ride controls to know the location of all the vehicles and, in some cases, the travel is controlled closely but without or with minimal use of conventional tracks. The scenic element including the doors  1120 ,  1124  would be placed in the “path” of the free ranging vehicle such and the vehicle acts to actuate the doors  1120 ,  1124  when it passes through the plane and/or sweep of these scenic elements. 
       FIG. 12  illustrates a ride vehicle  1200  that may be used with the scenic element shown in  FIG. 11  to actuate the doors  1120 ,  1124 . As shown, the scenic element-actuating vehicle  1200  includes a base or body  1210  with one or more seats  1252  for seating passenger(s)  1250 . The body  1210  includes a set of wheels, casters, or other components (such as an electric motor or the like)  1206  that allow the vehicle  1200  to be driven within a ride (such as a free ranging ride by components not shown) at a particular velocity along a path on the platform  1170 . Specifically, this path includes the screen or scenic element shown in  FIG. 11  with the side-by-side doors  1120 ,  1124 , and the vehicle  1200  is adapted to actuate the doors  1120 ,  1124 . 
     To this end, the vehicle  1200  includes a roof assembly  1204  with covers or panels (e.g., fabric or transparent/translucent materials)  1220 . The roof assembly  1204  is attached at ends via mounting elements  1236 . The top  1204  includes a set or at least a pair of actuation or levitation rail assemblies  1210 ,  1220  that extend along the length of or perimeter of the vehicle body  1210 . The body  1210  differs from others shown in that it is generally spherical in shape, and the rail assemblies  1210 ,  1220  again include a rail  1212  housing a plurality or array of magnetic elements  1216  that are covered by a protective cover or shield  1214 . The rail assemblies  1212 ,  1220  are positioned approximately at the midpoint of the spherical body  1210  with their location chosen to provide alignment with the magnetic elements  1128 ,  1129  on doors  1120 ,  1124  such that the vehicle  1200  functions to actuate or move the doors  1120 ,  1124  when the vehicle  1200  passes in proximity with the doors or in their plane. 
     In some embodiments, the scenic elements will be objects other than more traditional appearing doors that are placed in the path of a scenic element-actuating vehicle, and during operation, these objects are actuated or moved out of the way in response to the vehicle coming in proximity and/or contact with such objects. For example,  FIG. 13  shows a ride system  1300  similar to that shown in  FIG. 1  but with a first screen assembly  150  replaced with differing “screens” or show/scenic elements. As shown, a first and second scenic element  1310 ,  1320  is placed over the track  120  or in the path of the vehicle  132 . The scenic elements  1310 ,  1320  may be rigid or statue-type show characters or they may be animatronic characters operable to move and/or otherwise respond to the approaching vehicle  132 . The elements  1310 ,  1320  have bodies  1312 ,  1322  mounted or supported upon pedestals  1314 ,  1324 , and these pedestals  1314 ,  1324  are pivotally supported over the tracks  120  such that the elements may be actuated or forced out of the path of the vehicle  132 . To this end, the scenic elements  1310 ,  1320  each includes a magnetic element  1318 ,  1328  on their bodies  1312 ,  1322  that are positioned to be aligned with one or more of the actuation or levitation rails  144  on the vehicle  132 . In this manner, the elements  1310 ,  1320  are actuated or caused by magnetic forces to pivot out of the path of the moving vehicle  132  as described above for screen elements  156  with regard to  FIG. 1 . 
     The illustrated embodiments of ride systems such as system  100  of  FIG. 1  emphasize use of the vehicle to actuate a screen or scenic element  150  that is positioned to be transverse or even orthogonal to a plane containing the track  120 . However, the concepts taught for actuating the screen assembly  150  may also be applied effectively to scenic elements in differing planes or spatial relation to the moving vehicle  132 . For example, it may be desirable to cover the track  120  of the vehicle such that passengers of the vehicle  132  cannot see the track or rails  120  such as giving the appearance of a vehicle in water or other surface that may be represented by the track covering or by images projected on such track covering. To this end, a plurality of track covering segments (or screen segments/scenic elements) may be arranged to cover the track  120  and extend in a plane that is parallel to the plane of the track  120  or at least transverse to the plane of the screen  150 . Each of these track covering segments or scenic elements would be pivotally mounted or supported and would include a magnetic element(s). A plurality of magnetic elements would be positioned on a lower surface of the body or base  134  (again, with like poles as those of the track covering segments or scenic elements being exposed or facing outward) such as in levitation or actuation rails or the like. Then, when the vehicle  132  passes in proximity of the track covering segments these segments are actuated or moved out of the way in a contactless or touchless manner by magnetic forces (or rollers may be used as discussed above such as with reference to  FIG. 10 ).
