Description

[0001] Cross-reference to related applications This application claims priority and benefit to U.S. Provisional Application No. 63 / 600,765, filed November 20, 2024, entitled “Systems and methods for fluid bearing-based translation systems,” which is hereby incorporated herein by reference in its entirety for all purposes. Background Technology

[0002] This section aims to introduce the reader to various aspects of the technology that may relate to the various aspects of the present technology described and / or claimed below. This discussion is believed to help provide the reader with background information to better understand the various aspects of this disclosure. Therefore, it should be understood that these statements are to be read in this light, and not as an admission of prior art.

[0003] Amusement parks typically include interactive areas, comprising rides and attractions. Some interactive areas may include numerous mechanical components that are susceptible to damage after repeated use, rendering them inoperable. Maintaining an amusement park can disrupt the visitor experience or otherwise prevent visitors from accessing certain interactive areas, potentially negatively impacting visitor attitudes towards the park. Therefore, it is desirable to provide mechanically durable features in the interactive areas of an amusement park that are relatively easier to maintain compared to other features with numerous mechanical components.

[0009] One or more specific embodiments of this disclosure will be described below. To provide a concise description of these embodiments, not all features of an actual implementation may be described in the specification. It should be recognized that, as in any engineering or design project, the development of any such actual implementation involves numerous implementation-specific decisions to achieve the developer's specific goals, such as adhering to system-related and business-related constraints, which may vary from one implementation to another. Furthermore, it should be recognized that such development work can be complex and time-consuming, but will remain a routine task for those skilled in the art who benefit from this disclosure in design, manufacture, and production.

[0010] When describing the elements of the various embodiments of this disclosure, the articles “a,” “an,” “the,” and “the” indicate the presence of one or more elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that additional elements may exist besides those listed. One or more specific embodiments of the embodiments described herein will be described below. To provide a concise description of these embodiments, not all features of an actual implementation may be described in the specification. It should be noted that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer’s specific goals, such as complying with system-related and business-related constraints, which may vary from one implementation to another. Furthermore, it should be noted that such development work may be complex and time-consuming, but will remain a routine task of design, manufacture, and production for those skilled in the art who benefit from this disclosure.

[0011] This disclosure relates to a fluid bearing system that can be used in conjunction with amusement park attractions, such as guiding, directing, or otherwise transporting visitors through amusement park rides or experiences. Some amusement park rides may use mechanical conveyor systems having one or more mechanical conveying components (e.g., moving mechanical conveying members), such as wheels on a conveyor belt, a conveyor belt, a feeder, etc. When operating a mechanical conveyor system, the mechanical conveying components are subjected to mechanical stresses, such as strain exerted by the weight of the visitors and / or the ride, and / or by friction between the mechanical conveying components and the tracks of the conveyor system and / or the ride. Repeated mechanical stresses may eventually cause the mechanical conveying components to break or otherwise become inoperable. Therefore, in response to breakage or to prevent breakage, maintenance operators may replace, repair, or otherwise maintain the mechanical conveyor system, such as by replacing one or more of the mechanical conveying components. As the number of mechanical conveying components increases, maintaining the mechanical conveyor system becomes increasingly expensive due to, for example, downtime of the amusement park ride due to maintenance or repair. It is now recognized that it is desirable to utilize a conveyor mechanism for amusement park rides that has fewer mechanical conveying components and / or reduces the mechanical stress on the components of the amusement park rides, thereby reducing downtime of amusement park rides attributable to maintenance.

[0012] This document provides a fluid bearing system that uses fluid support to allow a ride platform (e.g., a ride vehicle) to glide along a track. The fluid bearing system includes a linear motor subsystem and a fluid support subsystem (e.g., a fluid support system). The linear motor subsystem includes a motor (e.g., a linear motor, an electromagnetic coil) or other conveying components that provide forward thrust (e.g., in the direction of travel) to the ride platform traveling along the track. The fluid support subsystem provides a force to the ride platform that reduces friction between the track and the ride platform, thereby reducing the load applied by the motor. The fluid support subsystem includes a fluid conduit that provides a fluid flow through its outlet. The pressure of the fluid flow applies a buoyancy force that lifts the ride platform (e.g., in a direction substantially perpendicular to the direction of travel), thereby reducing friction between the ride platform and the track. Reducing friction between the ride platform and the track improves track life by reducing the mechanical stress on the ride vehicle and / or the track. Furthermore, reducing friction reduces the amount of power provided by the motor to provide the desired thrust, thereby improving motor life.

[0013] Considering the foregoing, Figure 1A perspective view of an amusement park ride 10 with a fluid bearing system 12 is shown. The amusement park ride 10 includes a ride platform 14 that supports, holds, or otherwise transports riders 16 along a track 18 (e.g., a hydrostatic track system) through the amusement park ride 10 or another attraction within the amusement park. Although only one rider 16 and one ride platform 14 are shown, another embodiment of the fluid bearing system 12 may include any number (e.g., 1, 2, 3, 4, 5, or more) of ride platforms 14 with any number of riders 16.

[0014] During operation of the amusement park ride 10, one or more linear motors 20 (e.g., electric motors, electromagnetic motors, electric motors) of the fluid bearing system 12 can be operated to move the ride platform 14 along the track 18 in the direction of travel 22. In this way, the ride platform can transport passengers 16 to different attractions or stations within the amusement park ride 10. In some embodiments, the linear motor 20 may include an electric motor that actuates wheels, causing the ride platform 14 to move along the direction of travel 22. Alternatively, the linear motor 20 may include an electromagnetic motor that generates a magnetic field acting on a magnetic material 24, thereby moving the ride platform 14 along the direction of travel. As shown, the linear motor 20 is disposed on the track 18, and the magnetic material 24 is disposed on the ride platform 14. Therefore, in one embodiment, the ride platform 14 may not have a motor. However, in some embodiments, the linear motor 20 may be disposed on the ride platform 14, and the magnetic material may be disposed on the track 18. That is, in some embodiments, one or more rotors (e.g., one or more riding platforms 14) may include linear motors 20, stator (e.g., track 18) may include motors, or combinations thereof. In some embodiments, riding platform 14 may include brackets, baskets, benches, seats, and / or platforms that hold or otherwise support visitors 16.

[0015] Some rides in amusement parks may utilize a conveyor system for transporting passengers, which includes a relatively large number (e.g., 100 or more, 200 or more, 500 or more, 1000 or more) of mechanical conveying components or parts (e.g., wheels, conveyors, belts, feeders, etc.). Operating the mechanical conveying components subjects them and / or mechanical conveying parts to repeated mechanical stresses, which may (ultimately) cause the mechanical conveying components to break or otherwise render them inoperable. Compared to such systems that use only mechanical conveying components, the disclosed fluid bearing system 12 can significantly reduce the mechanical stresses on the components (e.g., mechanical parts) of the fluid bearing system 12 by means of a fluid support device 26 that provides an upward force 28 to the ride platform 14.

[0016] The fluid support device 26 may include a fluid conduit (not shown) that provides a fluid flow that applies an upward force 28, such as... Figure 3B As described in more detail herein. For example, the fluid support device 26 may be operable to discharge a fluid flow in the direction of the upward force 28. In some embodiments, the fluid may be a gas (e.g., air) or a liquid (e.g., water). In any case, by providing a lift to the riding platform 14 in the direction of the upward force 28, the fluid support device 26 may reduce mechanical stresses (e.g., friction) between the track 18 and the riding platform 14, as well as any mechanical conveying components. In one embodiment, when the linear motor 20 is an electromagnetic motor, the fluid bearing system 12 may have substantially no mechanical conveying components used in the conveying process, and therefore may be more robust compared to other conveying systems that use only primarily mechanical conveying components.

[0017] Therefore, the fluid bearing system 12 can be operated according to the control system 30, such as Figure 2 As shown in the block diagram. The control system 30 may include a processor 32 (e.g., a processing system) and a memory 34. The processor 32 may include one or more processing means, and the memory 34 stores instructions executable by the processor 32. The memory 34 may include one or more tangible, non-transitory, machine-readable media. By way of example, such machine-readable media may include RAM, ROM, EPROM, EEPROM, CD-ROM or other optical disk storage devices, magnetic disk storage devices or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of machine-executable instructions or data structures, and which can be accessed by the processor 32 or by any general-purpose or special-purpose computer or other machine having a processor.

[0018] The control system 30 may also include communication circuitry 36 and / or input and output circuitry 38 to facilitate communication with other components of the fluid bearing system 12, such as the operator interface 39, the fluid support subsystem 42, and / or the linear motor subsystem 44. The fluid support subsystem 42 may include one or more fluid support devices 26 that provide an upward force 28 to the seating platforms 14, thereby reducing friction between the seating platforms 14. The fluid support devices 24 may include, for example, one or more pumps 46, and, as well as... Figure 3BOther fluid flow devices are described in more detail below. The linear motor subsystem 44 may include the linear motor 20 and other components to facilitate movement of the riding platform 14 in the direction of travel 22. Furthermore, the control system 30 may be directly or wirelessly coupled to an operator input device or operator interface 39, which (in operation) can be used by a riding technician to provide input for controlling one or more riding features. As described, in some embodiments, the operator interface 39 or other components of the fluid bearing system 12 may be located remotely from the control system 30 and may, for example, be implemented on the mobility device.

[0019] The control system 30 can control the operation of the fluid support devices 26 of the fluid support subsystem 42, such as actuation of fluid conduits for providing fluid flow, the flow rate and / or flow type of the fluid flow, and the number and / or assembly of fluid support devices 26 for operation based on the position of the seating platform 14, determined by the control system 30. For example, the control system 30 can cause the fluid conduits to provide a type of flow, such as pulsed flow (e.g., discharging fluid every 1, 2, 3, or 4 seconds), continuous flow (e.g., discharging fluid over a period of time), etc. The fluid support devices 26 may include one or more fluid sources in fluid communication with one or more fluid outlet ports (e.g., via channels, conduits, etc.). Upon receiving a signal from the control system 30, one or more fluid support devices 26 may initiate the flow of fluid to a volume below the seating platform 14, such as by opening a valve to release fluid (e.g., providing fluid flow) and / or actuating one or more pumps 46 to influence the flow rate and / or flow pressure of the fluid flow. Therefore, the fluid support devices 26 may include suitable flow control elements such as valves, and one or more pumps 46 that can be operated under the control of the control system 30. In addition, the control system 30 can also control the de-activation of fluid flow and / or fluid discharge.

[0020] The control system 30 may also control the operation of the linear motors 20 of the linear motor subsystem 44, such as actuation of the motors to provide force to the riding platform 14, causing the riding platform 14 to move along the direction of travel 22. As described herein, the linear motors 20 may include linear motors and / or electromagnetic motors. The control system 30 may control, modify, or adjust (e.g., increase or decrease) the amount of current or power supplied to the linear motors 20, thereby controlling the amount of force supplied to the riding platform 14. In some embodiments, the control system 30 may supply current to each of the linear motors 20 such that the average amount of force supplied to the riding platform 14 (e.g., the average amount of force provided by the motors 20 within a specific section of the track, such as a linear section and / or a curved section) is substantially equal.

[0021] Therefore, the control system 30 can manage the position of one or more riding platforms 14 (e.g., riding vehicles) along the track 18 by coordinating the operation of the linear motor subsystem 44 and the fluid subsystem 42. That is, the control system 30 can actuate the fluid support device 26 to provide fluid flow and can also adjust the operation of the linear motor 20 to move the riding platforms 14 along the direction of travel 22. Furthermore, the control system 30 can adjust the fluid flow to increase or decrease the friction between the one or more riding platforms 14. Accordingly, by adjusting the fluid flow while simultaneously supplying current to the linear motor 20, the control system 30 can adjust the rate of the one or more riding platforms 14, thereby adjusting the position of the one or more riding platforms 14 along the track 18.

[0022] In some embodiments, the control system 30 may determine the distance between two or more ride platforms 14 on track 18 and use this distance to determine whether to adjust the position, speed, or acceleration of the ride platform 14. For example, the control system 30 may determine that a first ride platform 14 is within a threshold distance from a second ride platform 14. Thus, the control system 30 may adjust the operation of the linear motor subsystem 44 and / or the fluid support device 26 to slow down the first ride platform 14, the second ride platform 14, or both. Therefore, the control system 30 is able to manage traffic of multiple ride platforms along track 18 by controlling the position, speed (e.g., rate), acceleration, or combinations thereof of the ride platforms 14.

[0023] Figure 3A The illustrated embodiment shows a cross-sectional view of the fluid bearing system 12. The fluid bearing system 12 facilitates fluid flow within the gap or portion of the space between the fluid support subsystem 42 and the riding platform 14. Therefore, the riding platform 14 can travel on the fluid support within the fluid support subsystem 42, while being propelled by the linear motor subsystem 44. In one embodiment, the linear motor 20 of the linear motor subsystem 44 and the fluid support subsystem 42 can be fixed in place, while the riding platform 14 moves relative to the linear motor 20. That is, some components can be fixed, while others can move. For example, the linear motor 20 (or magnetic material 24) and the track 18 can be stationary. Furthermore, components of the fluid support subsystem 42, as described below, can be fixed in place, such as fluid conduits, water collectors, etc. In particular, Figure 3A An example embodiment of the linear motor subsystem 44 and fluid support subsystem 42 of the fluid bearing system 12 is shown. For simplicity, the linear motor subsystem 44 is generally described as... Figure 3A The discussion covers the fluid support subsystem 42, which is generally about... Figure 3B To elaborate.

[0024] As discussed herein, the linear motor subsystem 44 may include a conveyor that moves the riding platform 14 in the travel direction 22 (e.g., along an axis extending into the page), and the fluid support subsystem 42 provides an upward force 28 that reduces the amount of power output by the conveyor of the linear motor subsystem 44 to achieve the desired thrust along the travel direction 22.

[0025] The linear motor subsystem 44 may include a linear motor 20 (e.g., a linear motor, a linear induction motor), a riding platform support feature 60, and a magnetic material 24. For example, the linear motor 20 may be an electromagnet component, such as a coil wound with copper wire or a laminated iron core transducer. In such an example, the magnetic material 24 may include magnetic materials such as iron, nickel, cobalt, certain rare earth metals, etc. In embodiments where the linear motor 20 is not a linear induction motor, the magnetic material 24 may be omitted.

[0026] The linear motor 20 can provide forward thrust to the ride platform 14 via interaction with the linear motor 20, thereby moving the ride platform 14 in the direction of travel 22. In embodiments where the linear motor 20 is an electromagnetic motor, the linear motor 20 can generate a magnetic field 40, which can be used to induce thrust to propel the ride platform 14 along the direction of travel 22. It is now recognized that it is advantageous to use the control system 30 to adjust the current through the linear motor to provide an average force via the linear motor 20. For example, using the linear motor 20 to provide an average force can provide a smooth thrust on the track 18. However, at least in some instances, such as in thrill rides at amusement parks, it is desirable to provide a bumpy, uneven, or otherwise unstable ride. In such embodiments, it is desirable to make the forces provided by the linear motors 20 in different sections of the track different (e.g., the linear motors in the first section provide a first average force, and the linear motors in the second section provide a second average force different from the first average force).

[0027] The platform support feature 60 (e.g., pressure plate, plate, flat plate, pressure plate support frame) can be made of a relatively lightweight, abrasion-resistant material. In some embodiments, the platform support feature 60 is a metal, such as aluminum or an aluminum alloy. In some embodiments, the platform support feature 60 is a polymeric material (such as an ultra-high molecular weight (UHMW) polymer) having a tensile strength of 1000 psi or greater, 1500 psi or greater, 2000 psi or greater, 2500 psi or greater, 3000 psi or greater, or 3500 psi or greater. At least in some embodiments, such as when the fluid is water, it may be advantageous for the platform support feature 60 to comprise or be formed of a material with relatively low water absorption capacity (e.g., absorbing very little to no water). In some embodiments, it may be advantageous for the platform support feature 60 to have a relatively low coefficient of friction, allowing the platform 14 to slide relatively easily along the track (e.g., along the top surface of the fluid support subsystem 42 above the fluid conduit described below). For example, the platform support feature 60 may have a coefficient of friction of 0.2 or less, 0.15 or less, 0.12 or less, or 0.1 or less with respect to the material of the platform 14. As a non-limiting example, the platform support feature 60 may be UHMW polyethylene, polytetrafluoroethylene, or other relatively lightweight materials.

[0028] As shown, the seating platform 14 may include an upper body 65 and a lower body 67. The upper body 65 may be part of, integrated with, or otherwise coupled to the lower body 67 of the seating platform 14. The upper body 65 may include a basket, bracket, or other structure to support the passenger 16. The lower body 67 may be located below the track or at the level of the track. The lower body 67 may have multiple surfaces. For example, the lower body 67 may include a first surface supporting the seating platform support feature 60 and a second surface (e.g., a lower surface) disposed above the conduit of the fluid support subsystem 42.

[0029] As illustrated, the fluid support subsystem 42 may include a lateral support feature 64 (e.g., a lateral restraint structure or feature). The lateral support feature 64 prevents the riding platform 14 from moving along the lateral axis 66, thereby ensuring a smoother ride for the passenger 16 and maintaining the position of the riding platform 14 above the fluid support subsystem 42. For example, the lateral support feature 64 may be a guardrail coupled (e.g., physically coupled) to the track 18, and this guardrail guides the riding platform 14 along the track 18 in the direction of travel 22.

[0030] In some embodiments, the fluid support subsystem 42 may include a motor positioning member 68 (e.g., a plate, arm, beam, etc.). The motor positioning member 68 facilitates the positioning of the linear motor 20 along the transverse axis 66, allowing a flux of a suitable magnetic field 40 to flow through the magnetic material 24. As illustrated, the transverse support feature 64 may be coupled to the linear motor 20 via the motor positioning member 68. However, in some embodiments, the motor positioning member 68 may be coupled to the support rail 18 and / or the wall 70 of the transverse support feature, or the motor positioning member may be separated from the wall 70 and / or the rail 18.

[0031] Figure 3B The illustration shows a fluid subsystem 42 of the fluid bearing system 12. As illustrated, the fluid support subsystem 42 (e.g., each fluid support device 26) may include a fluid source 72 (e.g., a pressure chamber, fluid supply device), fluid conduits 74, a collector 76, a valve 78, one or more pumps 80, and a return line 82, which operate to provide a suitable flow rate and pressure of fluid to suspend the riding platform 14 in one or more sections of the track 18. One or more fluid conduits 74 of the fluid support subsystem 42 (e.g., fluid loops) may be selectively connected to each other to receive fluid (e.g., water) from the fluid source 72 (e.g., a container, reservoir, collection chamber) via a corresponding valve 78. One or more fluid pumps 80 may modify (e.g., increase or decrease) the flow rate of the fluid provided by one or more fluid support devices 26 (e.g., thereby providing force to the lower surface of the lower body 67 of the riding platform 14) such that the riding platform 14 is at least partially suspended due to the pressure of the fluid. The fluid bearing 12 may also include a water collector 76, which may be selectively connected to a fluid source 72 to allow water that provides an upward force 28 to the riding platform 14 to flow back. The fluid source 72 may be connected to a reservoir via one or more conduits for fluid maintenance, replenishment, and / or cleaning. In this way, the fluid flow provided by one or more fluid support devices 26 can be a closed system, facilitating cleaning of the fluid bearing system 12. That is, the control system 30 may adjust the operation of the pump 80 to circulate fluid through the fluid support subsystem 42.

[0032] While the fluid can be a gas or a liquid, it is currently recognized that liquids are less sensitive to load and have lower acoustic noise, properties that may be desirable for applications accommodating personnel. As illustrated, the fluid support subsystem 42 may include eight fluid conduits 74 disposed along the transverse axis 66 of the fluid support subsystem 42. Although eight fluid conduits 74 are shown, it should be noted that the fluid support subsystem 42 may include any number of fluid conduits (e.g., 1, 2, 3, 4, 5, 6, 7, 9, 10 or more) in a particular track section or location.

[0033] The control system 30 (e.g., a controller) controls the operation of components of the fluid support subsystem 42. For example, the control system 30 may send a control signal that adjusts (e.g., increases or decreases) the position of valve 78 to allow fluid to flow through conduit 74. The fluid flows in direction 90 toward collector 76. The fluid flow may be at least partially facilitated by gravity. In any case, the control system 30 may also actuate pump 80 to return fluid to fluid source 72. The control system 30 may adjust the rate of pump 80 so that fluid flows out of fluid conduit 74 at a suitable pressure to provide an upward force 28. In this way, the control system 30 can adjust the components of the fluid support subsystem 42 to ensure that a suitable upward force 28 is provided to the riding platform 14, thereby facilitating the movement of the riding platform along the direction of travel 22.

[0034] Figure 4 A top view of the track 18 of the fluid bearing system 12 is shown. In the illustrated embodiment, the track 18 may include a plurality of generally linear track segments 100 (e.g., straight track segments, straight track members) and curved track segments 102 (e.g., curved track members), extending along a travel direction 22 corresponding to each segment. Each linear track segment 100 and / or curved track segment 102 may include a linear motor subsystem 44 and a fluid support subsystem 42. For simplicity, in Figure 4 The symbols in the diagram refer to only a portion of the linear motor subsystem 44 and fluid bearing system 42 of the linear track segment 100 and the curved track segment 102. During operation, the ride platform 14 traverses the track 18 and moves relative to the individual linear motor subsystem 44 and fluid bearing system 42, which remain stationary and / or associated with the individual linear track segment 100 and / or curved track segment 102. The ride platform is propelled along the track 18 by the power of successive linear motors 20 of the linear motor subsystem 44, which are encountered as the ride platform 14 moves to subsequent track segments 100 and / or curved track segments 102. As discussed herein, the fluid bearing system 12 allows for more efficient traversal along the track 18. In one embodiment, the ride platform 14 may be motorless, with the motors 20 disposed on the track 18.

[0035] As illustrated, each fluid support subsystem 42 of the fluid bearing system 12 is fluidly connected via a return line 82. During operation, the fluid conduit 74 discharges fluid into the seating platform 14, thereby lifting the seating platform 14 via a buoyancy force (e.g., an upward force 28 discussed herein) relating to the fluid support subsystems 42. The fluid then flows into the return line 82 via the return inlet line 104 (e.g., as shown in the diagram). Figure 3B(As described in the document). During operation, the control system 30 of the fluid bearing system 12 can guide the fluid flow from the track 18 via the return inlet pipe 104 and return the fluid flow back to the track 18 via the return outlet pipe 106.

[0036] However, in at least some instances, the physical spacing between components can differ for linear track section 100 compared to curved track section 102. For example, it may be advantageous to reduce the relative spacing between linear motors 20 along curved track section 102 compared to linear track section 100. In this way, the ride platform 14 can withstand relatively smaller forces along the direction of travel 22, thereby slowing down the ride platform 14 as it moves along curved track section 102, providing a smoother ride for passengers 16.

[0037] As illustrated, the fluid bearing system 12 may include a position sensor 108 for obtaining position information. One or more position sensors 108 may be disposed in one or more sections of the track 18. For example, position sensors 108 may be disposed in each of the linear track section 100 and the curved track section 102. In some embodiments, position sensors 108 may be disposed on every other track section (e.g., every other linear track section 100 or curved track section 102). In any case, position sensors 108 may include motion sensors, light sensors, proximity sensors, or other sensors capable of detecting the riding platform 14 or otherwise generating data indicating the position of the riding platform 14 moving along the direction of travel 22 (e.g., position along the track 18). For example, position sensors 108 may be able to detect the riding platform 14 when it is within a threshold range of the position sensor 108 (e.g., 5 cm or more, 10 cm or more, 15 cm or more, or 20 cm or more). The control system 30 is communicatively connected to the position sensor 108 and determines the position of the riding platform 14 after receiving position data from the position sensor 108.

[0038] In some embodiments, the control system 30 may determine a subset of the linear motor subsystem 44 and / or fluid bearing subsystem 42 to be actuated based on position data received from position sensors. For example, the control system 30 may selectively actuate one or more segments (e.g., one or more linear track segments 100 and / or one or more curved track segments 102) adjacent to the segment corresponding to the detected position sensor 108 of the riding platform. Selective actuation of the linear motor subsystem 44 and / or fluid bearing subsystem 42 enables the fluid bearing system 12 to control different riding platforms 14 moving along the track 18 respectively. Furthermore, selective actuation of the linear motor subsystem 44 and / or fluid bearing subsystem 42 can reduce the power consumption of the fluid bearing system 12.

[0039] Figure 5 This is a first cross-sectional view of the seating platform 14 along the direction of travel 22. Figure 5 An example layout of the fluid support subsystem 42 is shown. In the illustrated embodiment, the bottom surface 112 of the seating platform 14 may cover approximately five fluid conduits 74 along the axis 114; however, the seating platform 14 may cover any suitable number of fluid conduits 74 that can elevate the seating platform 14 as it travels in the direction of travel 22. The bottom surface 112 of the seating platform 14 may be formed of a relatively lightweight material, such as those described with respect to the seating platform support feature 60.

[0040] In this embodiment, the seating platform 14 has a length of 110, and each fluid conduit 74 is separated from the other fluid conduit 74 by a distance 116 along the axis 114. The distance 116 between each fluid conduit 74 can be any suitable distance such that a sufficient amount of force (e.g., along the axis 118) is applied to the bottom surface 122 of the seating platform by the pressure of the fluid discharged from the fluid conduit 74 to the bottom surface 112 of the seating platform 14. For example, the distance 116 can be greater than or equal to 1 cm, greater than or equal to 2 cm, greater than or equal to 5 cm, greater than or equal to 10 cm, or greater than or equal to 15 cm. Although the illustrated embodiment shows the distance 116 between each fluid conduit 74 as substantially equal, it should be noted that the distance 116 can be different.

[0041] The fluid support subsystem 42 may include one or more fluid conduits 74 along axis 120. For example, the fluid support subsystem 42 may include two, three, four, five, or more than five fluid conduits 74 along axis 120. Furthermore, each fluid conduit 74 along axis 120 may be spaced apart by a distance (e.g., along axis 120) that is substantially equal to, less than, or greater than distance 116. Therefore, the bottom surface 112 of the seating platform 14 may be supported by N x M fluid conduits 74, where N is the number of fluid conduits along axis 114 and M is the number of fluid conduits along axis 120.

[0042] Figure 6 This is a top cross-sectional view of the linear motor subsystem 44. In the illustrated embodiment, each linear motor 20 is separated from the other linear motor 20 by a distance 130 (e.g., a linear motor separation distance) along axis 114. The distance 130 can be any suitable distance such that a sufficient amount of force (e.g., in the direction of travel 22) is applied to the seating platform 14. For example, the distance 130 can be 10 cm or more, 15 cm or more, 20 cm or more, 25 cm or more, 30 cm or more, 35 cm or more, or 40 cm or more.

[0043] In the illustrated embodiment, there are approximately three linear motors 20 along length 132. A portion of track 18 (e.g., length 132) may have a linear motor density of X / D, where X is the number of motors 20 and D is the length 132 of the track segment (e.g., corresponding to linear track segment 100 or curved track segment 102). In some embodiments, it may be useful to vary the linear motor density along track 18. For example, it may be advantageous to increase the linear motor density along track 18 during relatively straight portions of track 18 (e.g., one or more linear track segments 100). By increasing the linear motor density, the speed of the riding platform 14 along track 18 can be increased. For example, a higher linear motor density may allow for increased potential acceleration and potential maximum speed of the riding platform 14. In some embodiments, it may be advantageous to decrease the linear motor density along track 18, such as during curved portions of track 18 (e.g., one or more curved track segments 102). In this way, the linear motor density varies along the track 18, which can be used to control the speed of the ride platform 14 as the visitor 16 is moved through the amusement park attractions.

[0044] In some embodiments, it may be advantageous for one or more linear motors 20 to have an orientation such that the motor 20 is angularly offset from one of axes 114, 118, and 120. For example, the linear motor 20 may have an orientation substantially parallel to axis 114. In some embodiments, the linear motor 20 may have an orientation offset relative to axis 120. For example, one or more motors 20 on the curved track section 102 may have an orientation such that the riding platform 14 is guided upward along axis 118. Thus, the direction of travel 22 may be at least partially along the direction of the upward force 28.

[0045] Figure 7 It is for operation according to one aspect of this disclosure. Figure 1 The flowchart illustrates a method 150 for a hydraulic bearing conveyor system. At block 152, the control system 30 determines the presence of one or more riding platforms 14. For example, the control system 30 may receive sensor data from position sensor 108 indicating the position of the riding platform 14 along track 18 (e.g., a track segment). In some embodiments, the control system 30 may determine the number of riding platforms 14 along track 18.

[0046] At block 154, control system 30 can adjust the operation of fluid support subsystem 42. In some embodiments, adjusting the operation of fluid support subsystem 42 may include opening one or more valves 78 to provide an upward force 28 to riding platform 14. In some embodiments, adjusting the operation of fluid support subsystem 42 may include closing one or more valves 78, thereby lowering riding platform 14 to a rest position. In embodiments where fluid bearing system 12 may include position sensor 108, control system 30 may modify the position (e.g., open or close) of a subset of valves 78 corresponding to the current position of riding platform 14, causing riding platform 14 to rise from track 18. Furthermore, control system 30 may modify the position of another subset of valves 78 corresponding to one or more subsequent track segments along the direction of travel 22 of track 18.

[0047] At box 156, the control system 30 can adjust the operation of the linear motor subsystem 44. In some embodiments, the adjustment operation may include actuating the linear motor 20 to move the ride platform 14 along the track 18 in the direction of travel 22. In embodiments where the linear motor 20 is an electromagnetic motor, the control system 30 may actuate the linear motor 20 by increasing the amount of current flowing through the motor. In some embodiments, adjusting the motor operation may include de-actuating the motor to slow the ride platform down in the direction of travel 22. In embodiments where the linear motor 20 is an electromagnetic motor, the control system 30 may de-actuate the linear motor 20 by decreasing the amount of current flowing through the motor. In some embodiments, the control system 30 may adjust the operation of the linear motor subsystem 44 based on game elements. For example, the control system 30 may move the ride platform along the direction of travel 22 after determining that the visitor 16 has earned more points than a threshold, completed a story told by a character in the amusement park ride 10, stayed at a station corresponding to a specific track section for more than a time threshold period, or a combination thereof. In this way, the control system 30 can guide the visitor 16 through the amusement park ride 10 in an immersive manner.

[0048] As a non-limiting example of method 150, control system 30 may be able to independently control multiple ride platforms 14. For example, control system 30 may determine that a first ride platform 14 should move from a first position along track 18 to a second position along track 18. In some embodiments, control system 30 may determine that the first ride platform 14 should move based on game elements, the duration of the first ride platform 14 remaining at the first position exceeding a threshold, or a combination thereof. Thus, control system 30 may actuate a subset (e.g., one or more fluid support devices 26) of fluid support subsystems 42 and / or linear motor subsystems 44 within or near (e.g., adjacent to) the first position, the second position, or both. Furthermore, control system 30 may determine that a second ride platform 14 should move from a third position to a fourth position at approximately the same time period or at different time periods. Thus, control system 30 may actuate a subset of fluid support subsystems 42 and / or linear motor subsystems 44 within or near the first position, the second position, or both. In this way, control system 30 may provide a personalized experience for visitors 16 on the first and second ride platforms 14.

[0049] Therefore, this disclosure relates to a fluid bearing system that moves a ride platform along a track with relatively few moving mechanical parts. The fluid bearing system may include a fluid support system that provides an upward force to the ride platform, thereby reducing friction between the ride platform and the track. Furthermore, the fluid bearing system may include a linear motor subsystem that provides force to the ride platform, causing it to move in the direction of travel. By providing an upward force, mechanical conveying components, such as electromagnets, can move the ride platform with less power because this upward force significantly reduces friction between the ride platform and the track. In this way, the ride platform and / or track can be used for a longer period within the amusement park, thereby reducing costs associated with downtime and / or maintenance.
