1. Field of the Invention
The present disclosure generally relates to water amusement attractions and rides. More particularly, the disclosure generally relates to a system and method in which participants may be actively involved in a water attraction.
2. Description of the Relevant Art
Water recreation facilities have become a popular form of entertainment in the past few decades. Conventional water attractions at amusement parks typically involve using gravity to make water rides work, or they involve spraying water to create a fountain. The water rides that use gravity typically involve water flowing from a high elevation to a low elevation along a water ride surface. These gravity induced rides are generally costly to construct, and they usually have a relatively short ride time. Conventional fountains in water parks are generally passive attractions for people because guests of the parks usually cannot control the water flow in these fountains.
One water attraction that allows guests to become more actively involved with water spraying objects is described in U.S. Pat. No. 5,194,048 to Briggs. This attraction relates to an endoskeletal or exoskeletal participatory water play structure whereupon participants can manipulate valves to cause controllable changes in water effects that issue from various water forming devices.
A class of water attraction rides which are not gravity induced has been added to the theme park market. U.S. Pat. No. 5,213,547 to Lochtefeld discloses a method and apparatus for controllably injecting a high velocity of water over a water ride surface. A rider that rides into such injected flow can either be accelerated, matched, or de-accelerated in a downhill, horizontal or uphill straight or curvilinear direction by such injected flow. U.S. Pat. No. 5,503,597 to Lochtefeld et al. discloses a method and apparatus for controllably injecting high velocity jets of water towards a buoyant object to direct buoyant object movement irrespective of the motion of water upon which the buoyant object floats. U.S. Pat. Nos. 5,194,048, 5,213,547 and 5,503,597 are incorporated by reference as if fully set forth herein.
I. Control System
Embodiments disclosed herein provide an interactive control system for water features. In one embodiment, the control system may include a programmable logic controller. The control system may be coupled to one or more activation points, participant detectors, and/or flow control devices. In addition, one or more other sensors may be coupled to the control system. The control system may be utilized to provide a wide variety of interactive and/or automated water features. In an embodiment, participants may apply a participant signal to one or more activation points. The activation points may send activation signals to the control system in response to the participant signals. The control system may be configured to send control signals to a water system, a light system, and/or a sound system in response to a received activation signal from an activation point. A water system may include, for example, a water effect generator, a conduit for providing water to the water effect generator, and a flow control device. The control system may send different control signals depending on which activation point sent an activation signal. The participant signal may be applied to the activation point by the application of pressure, moving a movable activating device, a gesture (e.g., waving a hand), interrupting a light beam, or by voice activation. Examples of activation points include, but are not limited to, hand wheels, push buttons, optical touch buttons, pull ropes, paddle wheel spinners, motion detectors, sound detectors, and levers.
The control system may be coupled to sensors to detect the presence of a participant proximate to the activation point. The control system may be configured to produce one or more control systems to activate a water system, sound system, and/or light system in response to a detection signal indicating that a participant is proximate to an activation point. The control system may also be coupled to flow control devices, such as, but not limited to: valves and pumps. Valves may include air valves and water valves configured to control the flow air or water, respectively, through a water feature. The control system may also be coupled to one or more indicators located proximate to one or more activation points. The control system may be configured to generate and send indicator control signals to turn an indicator on or off. The indicators may signal a participant to apply a participant signal to an activation point associated with each indicator. An indicator may signal a participant via a visual, audible, and/or tactile signal. For example, an indicator may include an image projected onto a screen.
In some embodiments, the control system may be configured to generate and send one or more control signals in the absence of an activation signal. For example, if no activation signal is received for a predetermined amount of time, the control system may produce one or more control signals to activate a water system, sound system, and/or light system.
II. Water Fountain System
A water fountain system including a control system as described above may include a rotatable roof that may rotate in response to a stream of fluid. An embodiment of a water fountain system may include a roof having a friction surface. The roof may be movably coupled to a support member. The roof may rotate about an axis when a jet of water hits the friction surface. To facilitate rotation of the roof, the roof may be coupled to the support member via a bearing or bushing. The friction surface may include a plurality of protrusions (e.g., radially extending ribs, curved radially extending ribs, indentions, or protruding structures) providing a contact surface for receiving the water. A first conduit may direct water from a water source to a first nozzle located near the roof. For example, the first nozzle may direct a jet of water in a first direction toward the roof to cause the roof to rotate in a first direction (e.g., clockwise). A second conduit may direct water to a second nozzle also located near the roof. The second nozzle may direct a jet of water in a second direction toward the roof to cause the roof to rotate in a second direction (e.g., counterclockwise). The water source may include a reservoir for collecting and recycling at least a portion the water directed to the roof. The first and/or second conduits may include a nozzle. Additionally, the first and/or second conduits may be configured to direct water at an upper surface of the roof, or a lower surface of the roof. If a conduit is configured to direct water onto an upper surface of the roof, the roof may include an opening through which the conduit may extend. In some embodiments, only a single conduit may be present. In some embodiments, the first and/or second conduits may be moveably mounts such that one or both of the conduits may be moved to change the direction of rotation of the roof.
A flow control device (e.g., a pump or diverter valve) may be disposed upstream from the first conduit and the second conduit. The flow control device may direct water to one of the first or second conduits while restricting water flow through the other conduit. The flow control device may be located near the ground so that it may be adjusted by a participant.
A control system may be coupled to the flow control device. The control system may be manipulated by one or more participants to operate the flow control device. For example, the participant may apply a participant signal to an activation point. The activation point may include, for example, an optical touch button. The activation point may send an activation signal to the control system. In response to the activation signal, the control system may produce one or more control signals directed to one or more flow control devices. Additionally, the control system may produce one or more control signals directed to a sound system and/or a light system. In some embodiments, a plurality of movable roofs may be present. The control system may be configured to control each roof independently, or in conjunction with the others. The roofs may be co-planar, or distributed over several levels. In some embodiments, one or more activation points may be coupled to electrical control devices, such as switches or relays. In such embodiments, an activation point may send an activation signal to the electrical control device. The electrical control device may activate the flow control device in response to a received activation signal.
After a certain predetermined amount of time with no participant signal received, the control system may activate into an attract mode. This may consist of operating the water fountain system in a random, arbitrary, or pre-programmed manner. This operation may act to attract attention from onlookers or passersby, who may be enticed to interact with the water fountain system.
III. Water Cannon System
A water cannon system may include a tube from which water may be ejected in response to a control signal. A control system as described above may be coupled to the water cannon to control the operation of the water cannon. A water cannon may include a first hollow member including a closed end and an opposite end having an opening therein; and a second hollow member including first and second opposing open ends. The second hollow member is of smaller cross-sectional area than the first hollow member. The first and/or second hollow members may have a substantially circular cross-section, or some other shape. During use, the second hollow member is disposed in the opening in the first hollow member to form an airtight seal within the opening. The first open end of the second hollow member is outside or coplanar with the open end of the first hollow member. The second open end of the second hollow member is inside the first hollow member. In some embodiments the second hollow member may be bent or curved so that its second open end is lower than its first open end when the water cannon is parallel to the ground. Such a configuration may ensure that the second open end is below the water level in the cannon throughout the range of motion of the water cannon. The water cannon may also include a partition member with an opening therein. During use, the partition member may be disposed inside the first hollow member with the second hollow member disposed in the opening in the partition member. The partition member may be slidable along at least of a portion of the second hollow member. One or more stops may limit the range of motion of the partition member. The partition member may substantially form a partition from the exterior surface of the second hollow member to the interior surface of the first hollow member. The water cannon may also include one or more fluid inlets connected to a fluid source and effective to release fluid into the first hollow member during use. Additionally, one or more gas inlets connected to a source of pressurized gas, and effective to release a gas into the first hollow member during use may be present. The partition member may be disposed between a gas inlet and the closed end of the first hollow member during use. The control system may be in communication with a gas inlet and one or more activation points and one or more sensors. Additionally, one or more gas release valves may be provided. The gas release valves may be opened to release gas pressure when the water cannon is spent (e.g., substantially empty of water). The gas release valves may be closed when the water cannon is loaded (e.g., at a predetermined operational fluid level). The control system may control the opening and closing of the gas release valves.
In certain embodiments, a water cannon system may include a support apparatus configured to support the water cannon during use. The support apparatus may include a base and an upright member coupling the base to the first hollow member. The water cannon may be moveably coupled to the support apparatus. For example, the upright member may be coupled to the water cannon, or the base by a semispherical ball and cup connector. A sight may be coupled to the water cannon. A seat may be coupled to the base.
The act of applying a participant signal to an activation point may cause a projectile of water to be ejected from the water cannon. The activation points may be configured to signal the control system in response to the participant signal. The activation points may be located on or adjacent to the water cannon, or remote from the water cannon. The activation points may include an optical touch button. In some embodiments, one or more activation points may be coupled to electrical control devices, such as switches or relays. In such embodiments, an activation point may send an activation signal to the electrical control device. The electrical control device may activate the water cannon in response to a received activation signal.
The water cannon system may include a sensor in the vicinity of the activation points configured to signal the control system when a participant is near the activation points. The control system may be programmed to activate into an attract mode after a predetermined amount of time with no participant signal and/or no signal from the proximity sensor. This mode may include operating the cannon in a random, arbitrary, or preprogrammed fashion. This operation may serve to entice passersby to approach the activation points and participate with the water cannon system.
IV. Musical Water Fountain System
A musical water fountain system including a control system as described above may include a sound system for playing one or more musical notes, a water system for producing water effects, a light system for displaying lights, and a plurality of activation points for activating the sound system, the water system, and/or the light system. The water system may include a water effect generator, a conduit for carrying water to the water effect generator, and a flow control device. The flow control device may be configured to control the flow of water through the conduit. The flow control device may be operable in response to the water system control signals generated by the control system.
The act of applying a participant signal to the activation points may cause one or more of the following: a sequence of music notes may be produced, a water effect may be produced, and/or lights may be activated. A participant signal may be applied by the application of pressure, a gesture (e.g., waving a hand in front of a motion sensor), interrupting a light beam, or voice activation. At least one activation point may include an optical touch button. The activation points may be coupled to the control system. The activation points may be configured to sense a participant signal. The activation points preferably respond to a participant signal applied by a participant(s) and send an activation signal to the control system. The control system processes the signal. Depending on the programming of the control system, the control system may send a signal to the fountain system, and/or a second signal to the light system, and/or a third signal to the sound system.
The control system may be configured to provide participants with a visual, audio, and/or tactile indication at a predetermined time to alert the participants to apply a participant signal to a specific activation point. For example, an indicator associated with the control system may include an image projected on a screen. There may be a participant detection sensor in the vicinity of the activation point configured to signal the control system when a participant is near the activation point. When the sensor signals the control system, a light, sound, and/or tactile signal may be activated by the control system to indicate to the participants to apply a participant signal to the activation points. In some embodiments, one or more activation points may be coupled to electrical control devices, such as switches or relays. In such embodiments, an activation point may send an activation signal to the electrical control device. The electrical control device may activate the water system, sound system, and/or light system in response to a received activation signal.
After a certain predetermined amount of time with no participant signal received, the control system may activate an attract mode. This may consist of operating any combination of the light, sound, and/or water effects in a random, arbitrary, or pre-programmed manner. This operation may act to attract attention from onlookers or passersby, who may be enticed to interact with the musical water fountain system. After a predetermined amount of time with no participant detection signal, the control system may cease producing control signals, effectively turning the musical water fountain system off.
V. Interactive Water Game
An interactive water game including a control system as described above may include a water effect generator, and a water target coupled to the control system. In an embodiment, the water effect generator may include but is not limited to: a water cannon, a nozzle, and/or a tipping bucket feature. The water effect generator may be coupled to a play structure. During use, a participant may direct the water effect generator toward the water target to strike the water target with water. Upon being hit with water, the water target may send an activation signal to the control system. Upon receiving an activation signal from the water target, the control system may send one or more control signals to initiate or cease predetermined processes.
The water target may include a water retention area, and an associated liquid sensor. In an embodiment, the liquid sensor may be a capacitive liquid sensor. The water target may further include a target area and one or more drains. The water target may be coupled to a play structure.
In some embodiments, the interactive water game may include one or more additional water effect generators coupled to the control system. Upon receiving an activation signal from the water target, the control system may send one or more control signals to the additional water effect generator. The additional water effect generator may be configured to create one or more water effects upon receiving the one or more control signals from the control system. For example, the one or more water effects created by the additional water effect generator may be directed toward a participant. The additional water effect generator may include, but is not limited to: a tipping bucket feature, a water cannon, and/or a nozzle. The additional water effect generator may be coupled to a play structure.
A method of operating an interactive water game may include applying a participant signal to an activation point associated with a water system. An activation signal may be produced in response to the applied participant signal. The activation signal may be sent to a control system. A water system control signal may be produced in the control system in response to the received activation signal. The water system control signal may be sent from the control system to the water system. The water system may include the water effect generator. The water effect generator may produce a water effect in response to the water system control signal. The water effect generator may be directed toward a water target to strike the water target with water. An activation signal may be produced in the water target, if the water target is hit with water. The water target may send the activation signal to the control system. A control signal may be produced in the control system in response to the received water target activation signal. In an embodiment, the interactive water game may include an additional water effect generator. The control system may direct a control signal to the additional water effect generator if the water target is struck by water. The additional water effect generator may include, but is not limited to: a water cannon, a nozzle, or a tipping bucket feature. The additional water effect generator may produce a water effect in response to a received control signal. The water effect may be directed toward a participant.

I. Control System
In some embodiments, water amusement system 100 may also include a light system 116. Light system 116 may be configured to produce one or more light effects. Control system 101 may be coupled to light system 116. Control system 101 may be configured to generate light system control signals and send the light system control signals to light system 116. Light system 116 may be configured to generate a light effect in response to receiving a light system control signal. Control system 101 may be configured to generate a plurality of different light system control signals. Light system 116 may be configured to generate different light effects in response to different light system control signals.
In some embodiments, water amusement system 100 may include a sound system 114. Sound system 114 may be configured to produce one or more sound effects. In some embodiments, sound system 114 and water system 102 may be integrated together such that the sounds appear to be emanating from the water effects during use. Control system 101 may be coupled to sound system 114. Control system 101 may be configured to generate sound system control signals and send the sound system control signals to sound system 114. Sound system 114 may be configured to generate a sound effect in response to receiving a sound system control signal. Control system 101 may be configured to generate a plurality of different sound system control signals. Sound system 114 may be configured to generate different sound effects in response to different sound system control signals.
Collectively, water system 102, light system 116, and sound system 114 may be referred to as “water amusement features.” Water amusement system 100 may include one or more water amusement features as described above.
In an embodiment, water amusement system 100 may include one or more activation points 104 coupled to control system 101. Activation point 104 may be configured to receive a participant signal. A participant signal may be applied to activation point 104 by a participant who desires to activate the water amusement system. As used herein, a “participant” may refer to an individual interacting with the water amusement system primarily for entertainment, as distinguished from a system operator. As used herein, an “operator” may generally refer to an individual interacting with the water amusement system primarily as an agent of the owner of the water amusement system to coordinate the function of the water amusement system. In response to the participant signal, activation point 104 may generate one or more activation signals. Activation signals may be sent to control system 101. The activation signals may indicate that a participant has signaled the activation point. In response to the activation signal, control system 101 may generate one or more water amusement feature control signals. In some embodiments, activation point 104 may include a one or more of input devices 108. Input device 108 may be configured to receive a participant signal and transfer that signal to activation point 104. For example, input device 108 may include a hand wheel movably mounted in proximity to activation point 104. The wheel may not be directly coupled to activation point 104. Rather a sensor of activation point 104 may sense rotation of the wheel. For example, activation point 104 may include a capacitive proximity detector. The proximity detector may detect movement of one or more spokes of the wheel, or of a flat area, or flap coupled to an axle of the wheel. Movement of a sensed feature past the sensor may correspond to a participant signal. Activation point 104 may be configured to generate a plurality of activation signals in response to a plurality of participant signals. Control system 101 may also be configured to generate a plurality of control signals in response to the activation signals.
A participant detector 106 may be coupled to control system 101. Participant detector 106 may be configured to generate a detection signal when a participant is within a detection range of participant detector 106. The detection signal may be sent to control system 101. In response to a received detection signal, control system 101 may generate one or more water amusement feature control signals. This “attract” mode may entice participants that are in the proximity of water amusement system 100 to approach the system and interact with the system via activation point 104.
In an embodiment, control system 101 may be configured to stop the production of water amusement feature control signals in the absence of an activation and/or detection signal. In this manner, water amusement system 100 may be “turned off” in the absence of participants.
In an embodiment, control system 101 may be configured to produce random, arbitrary or predetermined water amusement feature control signals in the absence of a detection signal and/or activation signal. Thus, when no participants are present at activation point 104, control system 101 may revert to an attract mode, producing water amusement feature control signals to activate one or more of the water amusement features such that participants may be attracted to water amusement system 100. Control system 101 may be configured to generate water amusement feature control signals in the absence of an activation signal and/or a detection signal after a predetermined amount of time. When a participant begins to interact with activation point 104, control system 101 may resume generating water amusement feature control signals in response to the participant's input.
Activation point 104 may be configured to receive a participant signal by sensing pressure, motion, proximity, sound, or position of a movable activating device (e.g., a switch or trigger). Activation point 104 may be configured to respond to the participant signal. In one embodiment, activation point 104 may be configured to respond to a participant's touching of the activation point. In such an embodiment, activation point 104 may respond to varying amounts of pressure, from a very light touch to a strong application of pressure.
In another embodiment, activation point 104 may include a button that may be depressed by the participant to signal the activation point. In another embodiment, activation point 104 may include another type of movable activation device. For example, the activation point may be a lever or a rotatable wheel. In such embodiments, the participant may signal the activation point by moving the lever (e.g., reciprocating the lever) or rotating the wheel. In another embodiment, the activation point may respond to a gesture. For example, the activation point may be a motion detector. The participant may signal the activation point by creating movement within a detection area of the motion detector. The movement may be created by passing an object (e.g., an elongated member) or a body part (e.g., waving a hand) in front of the motion detector. In another embodiment, activation point 104 may be sound activated. The participant may signal the sound-activated activation point by creating a sound. For example, by speaking, shouting or singing into a sound sensitive activation point (e.g., a microphone), the activation point may become activated.
In another embodiment, activation point 104 may include a hand wheel. A hand wheel may be a rotary activated input device. In one embodiment, the hand wheel may include at least one sensor to determine the direction and number of times the hand wheel is rotated. In one embodiment, the hand wheel may produce a signal to turn “on” a feature or turn “off” a feature based on the number of turns of the wheel detected by the sensor. The signal to turn “on” and/or “off” may be sent based on a predetermined number of turns of the wheel. The signal to turn “on” or “off” may be produced by the same number of turns for each signal, or by a different number of turns. In another embodiment, the signal to turn “on” or “off” may be determined by the direction of rotation. The use of multiple sensors coupled to a hand wheel may allow the direction of rotation of the hand wheel to be determined. For example, a clockwise rotation of the wheel may produce an “on” signal, while a counterclockwise rotation of the wheel may produce an “off” signal. In another embodiment, the programmable control system may be configured to turn “on” successive features with each turn of the wheel (e.g., in a clockwise direction), and turn “off” the successive features in a reverse sequence with each turn of the wheel in the opposite direction (e.g., in a counterclockwise direction. Alternatively, the wheel may produce a signal to turn “on” features in a random or arbitrary manner with each turn of the wheel (e.g., in a clockwise direction), and turn “off” the features in a random or arbitrary sequence with each turn of the wheel in the opposite direction (e.g., in a counterclockwise direction).
Water system 102 may include one or more flow control devices coupled to one or more water effect generators. The flow control devices may allow control over the operation of the water effect. For example, flow control devices may include valves, such as solenoid-actuated valves. In some embodiments, a flow control device may include a pump. A valve used in a flow control device may be an air valve or a water valve. A water valve may allow the flow of water to a water effect generator to be altered. An air valve may allow the flow of air to a water effect generator to be altered. Generally, a flow control device may be capable of receiving a water system control signal from control system 101 and performing some action in response to the water system control signal to initiate, cease, and/or otherwise alter a fluid flow.
In one embodiment, a water valve may be opened, releasing a stream of water or closed, cutting off a stream of water based on the type of water system control signal received from control system 101. In addition to turning the flow of water on or off, a water valve may be configured to vary the volume, pressure, and/or direction of the water stream in response to a water system control signal from control system 101.
In one embodiment, a valve may be a diaphragm valve that may be actuated by a solenoid. Such valves may be used to control the flow of water or air through water system 102. The size of the valve may vary depending on the design of the water feature. For example, valve sizes may vary from about ½ in. to about 2 in. depending on the design of the feature.
A variety of water effect generators may be included in water system 102. Examples of water effect generators may include, but are not limited to: nozzles, water falls, water cannons, water fountains, water geysers, etc. Nozzles may be used to create a spray pattern. Spray patterns may include, but are not limited to, fan sprays, cone sprays, streams, or spirals. One or more water valves may also be coupled to a system of nozzles for producing a waterfall effect. The valves may be used to control the flow of water to the waterfall. A rain curtain effect may be produced by the system of nozzles. The nozzles may create streams of falling droplets that appear as a “curtain” of water. Combinations of valves activated in sequence may be used to produce an “explosion” of water in certain water effect generators. For example, geysers or cannons may use valves to control both air and water flow to produce a “pulse” of water. Another type of water effect generator may be a water container. For example, a water feature may include a rotatable water container. The water feature may be configured to at least partially fill the water container. At a predetermined time or level of water, the water container may be tilted such that some or all of the water in the container is poured out. Moving water features, such as the spinning roof water features described in more detail below, may also include flow control devices and water effect generators. For example, the direction of rotation of a spinning roof water feature may be determined by which of the nozzles are activated. A paddlewheel water feature may operate in a similar manner.
Flow control devices in water system 102 may be activated in sequence to control the flow of water and air to a water feature. In some embodiments, a plurality of flow control devices may be controlled by a single actuator. For example, in a geyser or cannon an actuator may control two or more valves in response to a single water system control signal to generate the pulse of water. In another example, a rotatable water container may include one or more actuators coupled to pneumatic or hydraulic cylinders and to water valves. The water valves may control filling of the container, while the pneumatic or hydraulic cylinders may control rotating the container.
Participant detector 106 may include any device capable of detecting a change in the surroundings and sending a signal to control system 101 in response. For example, participant detector 106 may include a photoelectric eye, an inductive proximity sensor, a motion sensor, a microphone, a flow sensor, a water level sensor, or any of many other sensors well known to one skilled in the art. In an embodiment, the participant detector 106 is a photoelectric eye. In such an embodiment, the photoelectric eye may send a signal to control system 101 in response to an object intersecting a projected beam of light. Participant detector 106 may produce a signal when a participant passes into the detection range of the detector. Control system 101 may send one or more control signals to water system 102, light system 116, and/or sound system 114 in response to a signal from participant detector 106. For example, control system 101 may direct the water amusement features to produce a variety of effects to attract the attention of the participant in the detection range of participant detector 106.
A control system input device 112 may be coupled to control system 101. Control system input device 112 may include, but is not limited to: a keyboard, an electronic display screen, a touch pad, a touch screen, any combination of these devices, or any other input device known in the art. Generally, control system input device 112 may include one or more devices capable of transmitting signals to and receiving signals from control system 101. In one embodiment, control system input device 112 may be a touch screen capable of displaying information to an operator and receiving input from the operator in the form of contact with the screen. For example, the screen may display a series of menus with different programming options for control system 101. The operator may choose a desired option by touching the appropriate area of the screen. Control system input device 112 may then transmit a signal to control system 101 corresponding to input provided by the operator. In this manner, the actions of control system 101 may be configured by the operator of water amusement system 100.
Control system 101 may include a processing unit capable of receiving one or more input signals, processing the signals, and sending one or more output signals in response. Control system 101 may be capable of being programmed, that is, configured by an operator to perform a variety of tasks. For example, tasks may include, controlling one or more features based on predetermine and/or random control parameters, and generating reports for an operator. Controlling one or more features may include, but is not limited to: receiving activation and/or detection signals, sending feature control signals to features based on received input signals, randomly, or according to a predetermined schedule. Additionally, controlling one or more features may include inhibiting a feature from performing one or more actions. For example, control system 101 may be configured to determine if a requested action would conflict with a preprogrammed control parameter. If such a conflict exists, control system 101 may inhibit the action from being performed. For example, a water feature may be inhibited from activating if a participant is detected too close to the water feature. Controlling features may also include monitoring feature control parameters. Data from monitoring control parameters may be used to generate an automatic notification to an operator if maintenance of a feature is required and/or to track feature use or performance.
Control system 101 may be programmed to turn on and/or turn off a feature after a determined period of time. For example, control system 101 may be programmed to open and close a fountain valve every 60 seconds. Control system 101 may also be programmed to turn on and/or turn off a feature after a determined period of time with no input from any activation point and/or participant detector. For example, if an activation point and/or participant detector has not been signaled for 5 minutes, control system 101 may be programmed to open one or more water valves and turn on one or more lights to display the capabilities of water amusement system 100. Programming control system 101 in this manner may serve to attract participants to interact with water amusement system 100. Control system 101 may also be configured to turn one or more features off if left on for a predetermined amount of time. In one embodiment, a variety of “on” and “off” time limits may be programmed into control system 101 such that water amusement system 100 may become an automated system in the absence of activation and/or detection signals. Other actions and combinations of actions, which are well known to one skilled in the art, may be programmed into control system 101.
Control system 101 may also be configured to generate and send indicator control signals. Indicator control signals may be sent to one or more indicators associated with one or more activation points (as described with referenced to
Control system 101 may include a logic controller. For example, the logic controller may include, but is not limited to: a programmable logic controller (PLC), an application specific integrated circuit, a general purpose computer configured to perform control system functions, and/or a facility control system. A logic controller may be used to monitor input signals from a variety of input points (e.g., sensors), which report various events and/or conditions. In response to input signals provided by input sensors, the logic controller may derive and generate output signals which may be transmitted via output points to various output devices (e.g., actuators, relays, etc.) to control the water amusement system. A logic controller may control a plurality of output devices.
Logic controllers may be configured in a plurality of ways with regard to voltage input and output, memory availability and programmability. For example, a logic controller may be configured to utilize input power of 120 VAC. In such a case, one or more actuators associated with the logic controller may be configured to utilize input power of 12 or 24 VDC. However, these power values should not be considered limiting. In an embodiment, a logic controller may include a plurality of PLCs combined in an Input/Output (I/O) chassis. In such an embodiment, each PLC may communicate with a supervisory processor or other PLCs while communicating with its own local I/O devices. The logic controller may be remotely programmed and/or controlled from a central computer system. For example, PLCs with the aforementioned capabilities may be obtained commercially from a plurality of vendors. Further information on PLCs may be found in U.S. Pat. No. 5,978,593 to Sexton, which is incorporated herein by reference.
II. Water Fountain System
Turning to
In an embodiment, an elongated support member 6 may support roof 2. Support member 6 may extend from a reservoir 8 to roof bearing 12. Reservoir 8 may hold water used in the water system. As depicted in
As used herein, a “protrusion” may generally refer to a feature located on the roof that is configured to increase friction or contact area between the roof and water that is directed toward the roof. Protrusions 4 may cause the surface of roof 2 to be uneven. Protrusions 4 may be protruding structures or indented portions of roof 2 that facilitate rotation of the roof by providing a contact surface for water directed at the roof. In an embodiment, protrusions 4 may be rib-like members. As used herein, a “friction surface” may generally refer to any surface that is configured to provide substantial resistance to a stream of water. An upper and/or lower surface of roof 2 may include a friction surface such that the roof may be contacted by water to cause rotation of roof 2. A friction surface may include protrusions 4.
A third conduit 18 may be coupled to first conduit 14 and second conduit 16 to supply water to the first and second conduits. Flow control device 10 may be located at a junction where the third conduit is coupled to the first and second conduits. Flow control device 10 may be a diverter valve, which directs water flow to either first conduit 14 or second conduit 16. Flow control device 10 may be located at any point on or before nozzles 5 and/or 7. Third conduit 18 may extend into reservoir 8 to a location below the water level in the reservoir. Pump 20 may be disposed along third conduit 18 to force water from the reservoir through the conduits. If flow control device 10 is adjusted to direct water from third conduit 18 to first conduit 14, water may be pumped to nozzle 5. Nozzle 5 may then direct a jet of water in a first direction at the bottom of roof 2. The jet of water from nozzle 5 may cause the roof to rotate in a clockwise direction. If instead flow control device 10 is adjusted to direct water to second conduit 16, nozzle 7 may direct a jet of water in a second direction to the bottom of roof 2. The jet of water from nozzle 7 may cause roof 2 to rotate in a counterclockwise direction. When water hits roof 2, it may be directed off in droplets to create a visual water effect. In an embodiment, the water passes from roof 2 back into reservoir 8 so that it may be recycled through the water system. In any of the embodiments described herein, nozzle 5 and/or nozzle 7 may include a plurality of nozzles.
In various embodiments, roof 2 may be composed of fiberglass, metal, plastic, or other suitable materials. Roof 2 may be substantially flat or it may be non-planar. Roof 2 may have a shape that resembles a figure such as, for example, a square, a circle, a triangle, a cone, a sphere, an umbrella, a pyramid, an animal, an insect, a plant, a dinosaur, a space ship, an inner tube, a boat, an auto, an airplane, etc. First conduit 14, second conduit 16, and third conduit 18 may be made of, for example, PVC, polyethylene, or galvanized steel pipes.

The radially inward portions 34 of the ribs may have a lower height than the radially outward portions 36. In this manner, radially inward portions 34 may tend not to block water directed at the radially outward portions 36 from nozzles 5 and 7. Alternatively, nozzles 5 and 7 may be positioned above or below the roof and angled to direct water above or below radially-inward portions 34 so that it may reach radially outward portions 36. Alternatively, the radially inward portions 34 may be absent.
In each of the embodiments described herein, nozzles 5 and 7 may be directionally adjustable so that the water directed from such nozzles may be directed in different directions without having to alter the positions of conduits 14 and 16. Nozzles 5 and 7 may be directionally adjusted manually or via a control system as described with reference to
In an embodiment, support member 6 may be shaped to resemble a figure such as, for example, a square, a circle, a triangle, a cone, a sphere, an umbrella, a pyramid, an animal, an insect, a plant, a dinosaur, a space ship, an inner tube, a boat, an auto, and or airplane. A sound system may be adapted to play sound effects that relate to the figures represented by roof 2 and/or support member 6. For example, support member 6 may have the shape of a dinosaur, and the sound system may be capable of producing sounds that would be associated with a dinosaur. Likewise, roof 2 may have the shape of, for example, a boat, car, or airplane, and the sound system may be capable of producing sounds generated by boats, cars or airplanes.
Each of the above-described water systems may include a light system and/or a sound system 23 as illustrated in
III. Water Cannon System
Turning to
When member 220 is disposed within opening 218, an airtight and watertight seal may be formed between member 220 and member 212 at opening 218. The members may be rigidly and/or permanently sealed, as with a weld or other permanent joint, or they may be sealed with the use of a gasket and/or sealant such as silicone or glue.
In an embodiment, water cannon 210 may further include a planar or disc shaped member, partition member 230. Partition member 230 may provide an opening 232 such that the second hollow member 220 is able to fit within the opening 232. In such a configuration, partition member 230 may be freely slidable along second hollow member 220. The device may also include a stop 254 to prevent the partition member 230 from sliding off the second hollow member 220 during use. Stop 254 may be coupled to second hollow member 220, to first hollow member 212, or to partition member 230. Stop 254 may be a ridge, bump, projection or a series of projections formed to prevent the partition member 230 from sliding off the second hollow member 220 during use. In certain embodiments, the stop 254 may be attached to or formed as a combination of attachments to, or projections in, the first and second hollow members 212, 220. In certain embodiments, open end 222 may be positioned so close to end 214 that a partition member 230 may be too large to slip off second hollow member 220. In such embodiments, a stop may not be present. In some embodiments, a second stop 264 may be present. Second stop 264 may prevent partition member 230 from sliding beyond an operational limit. For example, for proper function of water cannon 210, gas inlet 250 may be positioned such that gas entering via gas inlet 250 pushes partition member 230 toward open end 222. Second stop 264 may prevent partition member 230 from sliding beyond gas inlet 250. In some embodiments, gas inlet 250 may be attached to end 216. In such embodiments, a stop 264 may not be present.
The first hollow member 212 may also include one or more inlets 240 for a liquid, such as water. Inlet 240 may include a valve (not shown) to control the flow of liquid into the first hollow member 212. The valve may be passively operational such that the valve automatically closes when the fluid level in the reservoir reaches a predetermined level. The valve may open when the fluid level falls below the predetermined level. In other embodiments, the valve may be operated by a participant using the water cannon, or may be operated by a timer or control system. Inlet 240 may be in fluid communication with a fluid source, such as a water source. The fluid source may, in certain embodiments, include a pump for moving fluid from the source into the inlet.
As previously mentioned, reservoir 212 may include one or more gas inlets 250 disposed between end 216 of reservoir 212 and partition member 230. In some embodiments, gas inlets 250 may be connected to a control system or to a valve 252. A source of compressed gas or compressed air may be coupled to gas inlets 250. Valve 252 may be activated by a participant to cause reservoir 212 to become filled with gas. During use, opening valve 252 may allow gas to flow into the chamber, causing an increase in gas pressure to be produced within the chamber. This increase in gas pressure may cause partition 230 to move causing the ejection of a projectile of water. After the projectile has been ejected, additional gas may be inhibited from entering reservoir 212.
In an embodiment, a valve 253 may be positioned between valve 252 and gas inlet 250. Valve 253 may be configured to allow the gas pressure to build up between valves 252 and 253 such that the gas is pressurized to an appropriate pressure. To produce a burst of gas, valve 253 may be opened allowing the pressurized gas to enter reservoir 212. After a burst of gas is released, valve 253 may be closed and the air pressure allowed to increase. In this manner, an air line coupled to valve 253 may supply air for only the time required to eject the projectile of water. Valve 252 may serve as a main cutoff valve. During use, valve 252 may remain open to allow flow of air to reservoir 212. Valve 252 may be closed to prevent the water cannon from being used, e.g., during routine maintenance. The use of a dual valve system may allow gas from the gas supply system to be conserved and energy use of the device to be reduced.
Valve 252 and/or valve 253 may be connected to a control system 255. Control system 255 may be configured to accept remote signals from an activation point 262. Activation point 262 may be an activation point that generates an activation signal in response to a participant signal, as described with reference to
In an embodiment, control system 255 may be configured to operate at least one of valves 252 and 253 without any participant input. Control system 255 may be programmed to produce water projectiles at random, or at predetermined intervals. Control system 255 may also be programmed to produce water projectiles based on one or more predetermined triggering events. For example, a water projectile may be triggered by a detection signal from a participant detector, as described with reference to
During operation of water cannon 210, fluid may flow into reservoir 212 to at least partially fill reservoir 212 via fluid inlet 240. In an embodiment, the fluid may fill reservoir 212 at least until the fluid level completely covers open end 222. As the fluid level reaches a predetermined level, a valve in fluid inlet 240 may be closed or the fluid flow may be stopped by some other means. When reservoir 212 is full of fluid (e.g., the predetermined level has been reached), partition member 230 may be disposed near open end 224, and may rest against one or more stops 264. This may be described as the “loaded” cannon configuration. When the cannon is in the loaded configuration, valve 252 and/or valve 253 may be activated to release compressed gas or air into gas inlet 250. The compressed or pressurized gas may force partition member 230 to slide down second hollow member 220. As partition member 230 slides down second hollow member 220, the liquid in reservoir 212 may be forced into open end 222, through second hollow member 220 and out open end 224. In an embodiment, water cannon 210 may be configured such that the radius of the second hollow member 220 is no more than about one-third the radius of the first hollow member 212. It is believed that such a configuration may allow an “explosive” movement of partition member 230 upon entry of the compressed gas into first hollow member 212 resulting in a mass of water being forcefully ejected in a single spurt from second hollow member 220. In some embodiments, first hollow member 212 and second hollow member 220 may not have a circular cross-section. In such embodiments, first hollow member 212 and second hollow member 220 may be sized such that the cross-sectional area of first hollow member 212 is about 9 times the cross-sectional area of second hollow member 220. Alternately, the hollow members may be sized such that the hydraulic radius of second hollow member 220 is about one third the hydraulic radius of first hollow member 212. As used herein, “hydraulic radius” may generally refer to the cross-sectional area of a member divided by the length of the wetted perimeter of the member.
As used herein, a “projectile” may generally refer to a discrete volume or mass of water ejected from a water cannon due to a single release of gas into the first hollow member. A projectile may travel through its trajectory as a discrete, or substantially continuous, mass of water. It is understood that the projectile will break into smaller portions during the course of its trajectory. Nevertheless, the projectile may provide a sudden, large impact of short duration when it hits a target. A projectile is differentiated in this way from a continuous or semi-continuous stream of water, as in previous water gun type devices. A device as described herein, therefore, may provide a different and more fun sensation for a “target” person who hit with the projectile as compared to a continuous stream. A water cannon as described herein may provide the target or recipient with a sensation more akin to being hit with a water balloon or a bucket of water. This may be contrasted with a stream of water where the sensation may be similar to being sprayed with a water gun or water hose. In an embodiment, a projectile produced by water cannon 210 may have a volume of between about 8 oz. to about 60 gallons. For example, a projectile may have a volume of between 1 gallon to about 20 gallons or between 2 gallons and 10 gallons depending on the size of the water cannon.
By adjusting the pressure of the gas burst, the shape of the projectile may also be varied. For example, a high pressure, short burst of gas may cause a more diffuse projectile, while a low pressure, longer burst of gas may cause a more dense projectile. The type of projectile produced may be determined by the gas pressure, the flow rate of the gas, and the dimensions of the first and second hollow members.
In some embodiments, water cannon 210 may be equipped with a secondary water effect generator 276 (e.g., a nozzle, or valve) providing a water passage through closed end 214 of reservoir 212. Secondary water effect generator 276 may be used to create a “backfire” effect, wherein a participant interacting with water cannon 210 may be soaked rather than an intended target. For example, as described in further detail with reference to

As shown in
A plurality of water cannons, as described herein, may be used in combination to form an array of water cannons in various configurations. For example, two or more water cannons may be set up as opposing sides, such that the participants of one set of cannons may fire at the participants of an opposing set, and vice versa. In certain embodiments, the water cannons of opposing sides may fire water or other fluid of different colors so that non-adjacent cannons can be designated or recognized as being on a particular side. In other embodiments, a single water cannon station may include multiple barrels or multiple cannons operated by a single participant or a single control mechanism so that a rapid-fire effect may be achieved. Alternatively, a single water cannon may be configured to produce multiple projectiles of water. In such an embodiment, when the control mechanism is activated by a participant, the water cannon may produce multiple water projectiles, either one after another or all at once. When multiple projectiles are produced one after another, the water cannon may continue producing water projectiles until the control mechanism is no longer activated.
In an embodiment, a water cannon system, which includes one or more water cannons, may include a sound system and/or light system as discussed with reference to
IV. Musical Water Fountain System
An embodiment of a musical water fountain system is depicted in
In an embodiment, the musical water fountain system may include at least one instrument 400. Instrument 400 may be a real instrument (i.e., may actually generate sounds) or may be a structure formed to resemble an instrument (i.e., may only trigger a control system to make sounds). For example, instrument 400 may be an instrument included in an “orchestra.” In an embodiment, participants apply a participant signal to activation points 402 to activate the instrument. The participant signal may be applied by the application of pressure, moving a movable activating device, a gesture (e.g., waving a hand), interrupting a light beam, or by other means. Activation points 402 may be configured to respond to the participant signal. In one embodiment, activation point 402 may be configured to respond to a participant's touching of the activation point. Activation point 402 may respond to varying amounts of pressure, from a very light touch to a strong application of pressure. Alternatively, activation point 402 may include a button that may be depressed by the participant to signal the activation point. In another embodiment, activation point 402 may include a movable activation device. For example, activation point 402 may include a lever or a rotatable wheel. The participant may then signal activation point 402 by moving the movable activation device (e.g., reciprocating a lever or rotating a wheel). In another embodiment, activation point 402 may respond to a gesture. For example, activation point 402 may include a motion detector. The participant may then signal activation point 402 by creating movement within a detection area of the motion detector. For example, movement may be created by passing an object (e.g., an elongated member) or a body part (e.g., waving a hand) in front of the motion detector.
Activation points 402 may be located on or in the vicinity of instrument 400. Each instrument 400 may include a plurality of activation points 402. For example, instrument 400 may resemble a piano or a keyboard containing a plurality of keys. Each of the keys may include an activation point 402 (see
In one embodiment, each of activation points 402 may be configured to sense a participant signal and generate one or more activation signals in response to the participant signal (as described with reference to
Furthermore, when a participant signals an activation point, a second signal may be relayed to a water system 404 via control system 412. In response to the second signal, water system 404 may produce a water effect. Examples of water effects include, but are not limited to: spraying of water, generation of bubbles, and generation of smoke. The water effect of spraying water may include varying the height, direction, and/or volume of the water produced by the fountain when certain activation points are signaled. The water effect of spraying water may also include producing a projectile of water as previously described. Water system 404 may include at least one conduit 406, at least one flow control device (e.g., valve 408) disposed within conduit 406, and at least one water effect generator 410 connected to conduit 406 for producing a water effect. Conduit 406 may, for example, be made from materials such as PVC or galvanized steel. Valve 408 may be coupled to control system 412. The second signal may be relayed to valve 408 to signal it to open, thereby causing the water effect to be generate by water effect generator 410.
In an embodiment, lights 418 may be located near water system 404. When a participant signals an activation point a third signal may be generated by control system 412. The third signal may be relayed to lighting system, thereby activating selected lights 418 of the lighting system.
It is to be understood that the first, second, and third signals described herein may each be a single signal or may be a series of signals. For instance, an activation point may generate an activation signal and send it to control system 412. In response, control system 412 may transmit a signal to the sound system to produce a musical note. For simplicity, the “first signal” may be taken to include the signal generated by the activation point and the signal relayed by the control system.
Each of activation points 402 may be configured to generate the first, second, and/or third signals each time a participant signal having a predetermined magnitude is sensed by the activation point. For pressure activated activation points, the activation signals may be generated in response to a predetermined amount of force applied to the activation point. For motion-activated activation points, the activation signals may be generated in response to movement having a predetermined speed and/or direction or within a predetermined range.
In some embodiment, each activation point 402 may be associated with only one of the systems (i.e., the sound system, water system, or lighting system). That is, an activation point 402 may be configured to generate either the first, second, or third signal such that a participant may separately activate the sound system, water system, and lighting system by applying a participant signal to different activation points 402. Activation points 402 may include transducers for sensing the magnitude of the signal applied to the activation points. Activation points 402 may selectively generate the first, second, and/or third signals as a function of the magnitude of the signal applied to the activation point. In this manner, a participant may control which of the systems is activated by controlling the magnitude of the signal applied to the activation point. For instance, a pressure sensitive activation point may generate the first signal to activate the sound system in response to sensing a force below a predetermined magnitude, while the activation point may generate the second and/or third signals in response to sensing a force above the predetermined magnitude.
In an embodiment, the sequence in which a participant signals the activation points may affect the resultant sound quality of music generated by sound system 403. For instance, the sequence in which participant signals are applied to activation points 402 may determine the order in which musical notes are played by sound system 403. In an embodiment, various indications may be provided by control system 412 to participants at predetermined times to coordinate the activation of the sound system, water system, and/or lighting system to create a desired visual and audio display. The participant may apply a participant signal to an activation point immediately after receiving an indication at a pre-determined time.
The indication provided to the participants may be supplied by an indicator coupled to control system 412. Control system 412 may activate the indicator at predetermined times or in response to a signal from a proximity sensor located near the activation point. The indication provided by the indicator may be a visual signal (e.g., light), an audio signal (e.g., a tone), or a tactile signal (e.g., a vibration). The indication may be located in the vicinity of the activation point. In an embodiment, a separate indicator may produce an indication to a participant when to apply a participant signal to activation points to separately activate the sound system, lighting system, and water system.
In an embodiment, an indication may be provided by a conductor 416. As described herein, “conductor” may refer to an object, mechanism or person for coordinating the actions of the participants to create desired visual and/or sound effects by activating the sound system, lighting system, and/or water system. Conductor 416 may be an individual that motions and/or speaks to participants to signal the participants when to apply a participant signal to an activation point. Conductor 416 may speak into a microphone, and the volume of the conductor's voice may be increased by a speaker 420 directed toward the participants. Individual speakers 420 may be located proximate each instrument or set of activation points corresponding to an instrument so that conductor 416 may communicate to selected participants at different times. Alternatively, conductor 416 may be a robotic arm for directing the participants. In an embodiment, conductor 416 may be a projected image. For instance, different colors or images may be displayed on the screen at predetermined times, wherein each color or image corresponds to a different instrument, different group of instruments, or different activation points. The display of a particular color or image may indicate to selected participants to apply a participant signal to selected activation points. Platform 414 may support conductor 416. Platform 414 may be at an elevational level above the participants and activation points 402 so that the participants may easily see conductor 416. The control system 412 may be configured to control conductor 416.
An indicator, for example, lights 426 and 428 may indicate when a participant signal should and should not be applied to a certain activation points. Lights 426 and 428 may be coupled to control system 412, which may activate the lights at appropriate times. One of the lights may indicate when a participant should apply a participant signal to (e.g., stand on) one of activation points 402. The other light may indicate when the participant should discontinue application of the participant signal to the activation point. A musical note or sequence of musical notes may be played by sound system 403 in response to various participant signals applied to various activation points 402. It is to be understood that lights 426 and 428 may be different colors. For example, in one embodiment, light 426 may be red and light 428 may be green. In an alternative embodiment, a single light may be activated to indicate to a participant to apply a participant signal to an activation point. The light may be one of a variety of colors, such as yellow, green, red, blue, purple, and orange. After the participant has applied a participant signal to the activation point the light may be turned off to indicate when the participant should discontinue applying the participant signal to the activation point.
In an embodiment, control system 412 may receive activation signals generated in response to the participant signals applied at activation points 402. Control system 412 may then indicates to sound system 403 the appropriate time to play a particular note. Control system 412 may control operation of sound system 403 such that the resultant music is affected by the presence or absences of participant signals and the order in which such signals are relayed to control system 412. In this manner, whether or not a participant applies a signal to an activation point 402 and the time at which a participant applies a signal to the activation point may affect the music produced by sound system 403. Control system 412 may receive activation signals from activation points 402 and delay playing of sounds by sound system 403 for a predetermined time (e.g., ten seconds or more). Alternatively, sound system 403 may play a musical note substantially immediately with application of a participant signal. In an alternative embodiment, control system 412 may be programmed to cause a determined sequence of notes to be produced at a particular time so that a song is correctly played even when the participants do not contact activation points 402 at appropriate times. In an embodiment, control system 412 may be programmed to cause a song to play after a predetermined time with no participant signal.
In some embodiments, one or more activation points may be coupled to electrical control devices, such as but not limited to: switches and relays. In such embodiments, an activation point may send an activation signal to the electrical control device. The electrical control device may activate the water system, sound system, and/or light system in response to a received activation signal.
In an embodiment, a music water fountain system may include a plurality of different activation points for producing various sound, light, and/or water effects. Each of the activation points may activate an instrument, or one or more notes of an instrument when a participant signal is applied to the activation point. A conductor may be used to signal the activation of the instruments or of specific notes of the instruments. A group of participants may respond to the conductor's indications such that a musical tune may be produced.
In another embodiment, water from a musical water fountain system may be used to create at least some of the sounds produced by the musical water fountain system. For example, a plurality of activation points may be disposed about a musical water fountain system. The activation points may be coupled to a water system. The water system may include one or more water cannons as described above. In response to a participant signal, a control system may cause water to be fired at a sound-producing device. The water may be fired as a stream or a projectile. The impact of the water against the sound-producing device may produce a sound. For example, the sound producing device may be a series of gongs which, when struck with water may produce a ringing sound. Other sound devices, which may produce a sound when contacted with water, include but are not limited to: drums, bells, tubes, or chimes. It is envisioned that any percussive instrument may be used. In certain embodiments, non-percussive instruments, such as stringed instruments or wind instruments may be used. In such embodiments, the water may impact a mechanism configured to activate the instrument. For example, water may activate a bellow to sound a wind instrument, or a movable clapper, hammer or pick mechanism to activate a stringed instrument.
In another embodiment, the musical water fountain system may include a bubble organ. The bubble organ may include a series of pipes arranged in a manner typical of a pipe organ. In an embodiment, the pipes may be made of a substantially transparent material. A series of activation points may be disposed about the bubble organ. In response to a participant signal, the bubble organ may produce sound while simultaneously producing a water effect. The water effect may include the production of bubbles. The bubbles may be produced such that they emanate out of a top portion of the pipes. A lighting system may also be coupled to the pipes such that the participant signal activates one or more lights such that the bubbles appear to be colored as they move through the pipe.
In another embodiment, the musical fountain may be constructed in the form of a walkway. A plurality of activation points may be arranged on the surface of the walkway such that participants may step on the activation points. The activation points may be configured to respond to the weight of the participants. As the participants move along the walkway, they may contact the activation points such that a musical and/or a water effect is produced. For example, when a participant steps on an activation point, a portion of a song may be played by a sound system of the music water fountain system. Additionally, a water effect, such as a stream of water, may be produced.

In an embodiment, water target 500 may include a target area 506 with one or more water capture openings 508. Water capture openings 508 may provide a passage through target area 506 into water retention area 502. If water target 500 is hit, water may pass through water capture opening 508 into water retention area 502. The water entering water retention area 502 may cause a change in a monitored electrical property of liquid sensor 504. For example, the water may cause a change in capacitance, or resistance of liquid sensor 504. A suitable capacitive liquid sensor system may be purchased from the Balluff Inc. of Florence, Ky. The change in the monitored electrical property may be registered as an activation signal by the control system. One or more drains 510 may be provided in water retention area 502 to allow captured water to drain. By draining the water from water retention area 502, the monitored electrical property may be returned to a “normal” state. Thus, water target 500 may be reset, and prepared to register subsequent hits.
In an embodiment, one or more water targets 500 may be coupled to a musical water fountain system. In such an embodiment, water target 500 may act as an activation point. The musical water fountain system may include one or more water effect generators (e.g., nozzles, water cannons, etc.) moveably mounted for participant interaction. A participant may direct water from the one or more water effect generators toward water target 500. If the participant hits water target 500, an activation signal may be sent by the water target to a control system. The control system may then send one or more control signals to the musical water fountain system to trigger one or more water effects, sound effects, and/or light effects.
In other embodiments, one or more water targets 500 may be associated with a play structure. Again, water targets 500 may act as activation points. A participant may direct water from one or more water effect generators (e.g., nozzles, water cannons, etc.) toward one or more water targets 500. If a participant hits one of water targets 500, the water target may send an activation signal to a control system. The control system may be coupled to one or more water systems associated with the play structure. The control system may send one or more control signals to the water systems to generate one or more water effects. In a competitive arrangement of such a system, the one or more water effects generated may be directed toward another participant. For example, each participant may be seated at a water cannon station as described with reference to
In an embodiment, liquid sensor 504 may include a capacitive liquid sensor, or other liquid sensor such as is known in the art. An advantage of a capacitive liquid sensor may be its relatively low installation and operating costs as compared with mechanical liquid sensing systems.
Each of the embodiments discussed above may be used individually or combined with any one or more of the other embodiments. Other rides or amusement devices, such as may be found in a wet or dry amusement park, may also be present. A control system as discussed concerning
