CROSS REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application claims benefit of the earlier filed U.S. Provisional Applications Nos. 60/628,226 and 60/628,227 both filed Nov. 17, 2004, which are incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION  
       [0002]     The invention relates to a water feature, specifically a controller and apparatus that imparts an energetic pulse wave into a laminar flow tube issuing from, for instance, a laminar flow water jet.  
       BACKGROUND OF THE INVENTION  
       [0003]     It is often desired to utilize a fluid, such as water, as part of a display or attraction. Increasingly, the popularity of using water attractions as an integral part of domestic and commercial landscaping has moved architects and landscapers to push further and further into incorporating the decorative aspects of these water features into new building and sites. These features are incorporated through swimming pools, spas, ponds, lakes and other water features and sources found in the typical property. Various types of fountains adorn public and private plazas, parks, advertisements, and amusement parks.  
         [0004]     To this end, recent interest and developments have been made in producing smooth, laminar flows of water which give the appearance of a solid glass or clear plastic rod in various water attractions, for instance, the fountain presentation in the Bellagio Hotel in Las Vegas or the Dancing Frogs attraction at the EPCOT center of Disney World, as described in U.S. Pat. No. 5,078,320 to Fuller, et al. These attractions incorporate laminar flow water jets. These devices jet water like a fountain, but the water has a minimum of turbulence in it that is the water is predominantly laminar. The water tension of the flow issuing forth provides the tubular shape. The water tension forms an outer jacket around the laminar flow, creating a laminar tube shape. This results in the smooth rod structure of the streams that are issued from the jets.  
         [0005]     A first step in providing a laminar flow tube in a laminar flow jet is to produce a laminar water flow. These jet and fountain devices have used a wide variety of elements to instill laminarity into a water flow. Various attempts with a variety of elements have been made at reducing laminarity in a water stream. For example, U.S. Pat. No. 4,393,991 to Jeffras et al. discloses a sonic water jet nozzle which utilizes an elongated conical nozzle which includes fin-like members to reduce the turbulence of the water and to produce a laminar flow of water. U.S. Pat. No. 3,321,140 to Parkison et al. discloses an attachment for a faucet which utilizes a series of fins in a cylindrical nozzle for producing a laminar flow of water to reduce the splash on the bottom of a sink or tub. U.S. Pat. No. 3,730,440 to Parkison teaches a laminar flow spout which utilizes a plurality of independent nozzles arranged within a single spout which results in a plurality of streams having laminar flow characteristics. Systems like these and Applicant&#39;s co-pending application for a Laminar Flow Water Jet with Pliant Member provide the laminar flow tubes that are so desirable in water attractions.  
         [0006]     In addition to providing a laminar flow, it is often desirable to provide a controlled interruption to the jet operation for the purposes of providing an artistic display. Again, referring back to the EPCOT display, the laminar flow jets function in a timed manner to provide an interesting display of water leaping from the frogs. There are various methods for producing columnarization or a controlled interruption of the laminar jet flow to produce discrete tubes. This is typically done by a mechanical diversion of the flow or a part of the flow for a controlled period of time.  
         [0007]     Examples of this type of device can be seen in U.S. Pat. No. 4,889,283 which discloses a stream diverter that utilizes a diverter nozzle to split an output stream in a controlled fashion. This results in an interruption of the columnar length prior to its emergence from the device. Similarly, U.S. Pat. No. 5,802,750 discloses a spinning disk that interrupts the laminar flow after leaving the laminar flow water jet with a rotating wheel to simulate a jumping fish. However, these devices do not permit interruption of the laminarity without diversion of the flow jet or disruption of the column of the jet and, further, the devices do not provide a controllable energetic impulse or pulse to interrupt the jet.  
         [0008]     Similarly, along these lines, in U.S. Pat. No. 6,717,383 a programmable fountain controller is shown for varying the flow rate of a fountain pump in a predetermined manner so as to generate dynamically changing flow patterns. These include an audio input amplifier that sends signals to vary the pumps in time to the input. This design however fails to provide a pulse wave or any similar disruption of the flow in a laminar flow water jet.  
         [0009]     Although there are devices available that add vibratory or oscillatory pulses into a water stream, for instance in U.S. Pat. No. 3,924,808 that shows a shower head vibrator is attached to the resilient coupling provided between the water outlet pipe and the shower head that produces an oscillatory pattern in the flow, these devices do not provide the controlled interruption necessary to maintain laminarity in a laminar flow water column. Instead, these devices oscillate a turbulent flow in a random fashion, typically to produce a massaging pulse or oscillating pressure variation for massaging a user. They fail to provide for a laminar flow column, much less the interruption of the laminar flow column in a controlled fashion with an energetic pulse.  
         [0010]     To date, no method has been able to selectively interrupt the laminarity within the laminar jet tube of a laminar water jet without significant visible disruption or diversion of the laminar jet. Moreover, no method to date has allowed for a level of variation in the interruption of the laminarity in the laminar jet tube that would allow for both discrete jet tube lengths, i.e. columnarization, as well as multiple segments within a tube or columnarized flow, i.e. discrete segmentation. Furthermore, no system can produce columnarization or segmentation and allow for discrete multiple color effects in the tubes or in columns. Thus a need exists for a controller and a method of controlling a laminar water tube or jet that allows for selective interruption of the laminarity within the tube with or without the discrete columnarization of the tube, especially a method that utilizes an energetic pulse.  
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE INVENTION  
       [0043]      FIG. 1  shows a cross sectional view of the exemplary embodiment of the instant invention. The exemplary embodiment of  FIG. 1  comprises a housing  100 , a housing top  110  with an at least one jet outlet  115  extending there through, and a housing base  120 . Flowing into the housing base  120  is an at least one water input, in this instance a first water input  130  and a second water input  140 . Within the housing  100  a laminar water flow channel  500  resides. Additionally, a lighting orifice  165  is provided and passes through the base plate to couple to a lighting tube  170 . The lighting tube  170  extends into the laminar water flow channel  500  and through the housing  100  toward the at least one jet outlet  115 . The lighting tube  170  is provided to apply lighting effects to the exiting water. The tube may utilize any appropriate lighting system, including but not limited to, conventional incandescent, halogen, fiber optic, LED, nano scale lighting devices or similar lighting systems. Furthermore, although the exemplary embodiment utilizes a light tube, any appropriate manner of focusing the lighting system may be used to illuminate the exiting water jet.  
         [0044]     In the exemplary embodiment shown, internal to the housing  100  and the laminar water flow channel  500  flows from the plurality of inputs  130 ,  140 , into an at least one baffle member  250  with a plurality of orifices  145  situated therein. Alternatively, the baffle member may be omitted from further exemplary embodiments. Above the plurality of inputs  130 ,  140  shown, an at least one filter member, in this case a plurality of filter members, is provided.  
         [0045]     A first filter member  210  is provided in the laminar water flow channel  500  of the exemplary embodiment show in approximately the middle of the housing chamber. Variations in the placement, the positioning, the spacing, the shape, the size, and the number of members or screens can be provided alone or in conjunction with variations in sizes, density, construction, shapes, mesh size, screen gauge, and other variables to suit the particular design constraints of a further exemplary embodiment without departing from the spirit of the invention. Surrounding the interior of the housing  100  is an at least one elastomeric or pliant member  300  through which the laminar water flow channel  500  passes.  
         [0046]     Pliant member  300  can be comprised of, for example, closed cell foam, rubber compounds, PVC and rubber compounds, air pillows, gel filled members, foam, or similar pliant materials. Pliant member  300  aids in damping vibrations within the water as it passes through the laminar water flow channel  500 . Particularly pliant member  300  aids in mitigating pump surges and similar pressure variances as well as aiding in improving the laminarity in the water flow. The at least one pliant member  300  may also be incorporated, in combination with the pliant member shown around the housing or alone, into an at least one of the at least one filter members.  
         [0047]     In the exemplary embodiment shown, in addition to the first filter  210  the at least one filter member includes a further series of three filter members  220 ,  230 ,  240  above the first filter member  210 , which helps provide additional laminarity to the water as it flows towards the at least one jet outlet  115 . The additional filter members  220 ,  230 ,  240  are also shown as conical in shape. However, it should be understood by one of ordinary skill in the art that the variations in geometry, number, and placement/spacing of the filter members are within the spirit of the invention. Additionally, as mentioned the at least one pliant member  300  can include an at least one pliant member mounted on or within an at least one of the at least one filter members. Further, it is readily evident to those of ordinary skill in the art that the controller  400  and the at least one pulse generating component can be included in existing laminar devices and the exemplary embodiment is only one example of such a system.  
         [0048]      FIG. 2  shows a close up view of the solenoid and controller of the instant invention. In addition to the laminar flow jet  10 , a control package  400  is provided on the exterior of the housing  100 , as shown in  FIG. 1 . It would be understood by one of ordinary skill in the art that the controller  400  could be located on any laminar flow device on any appropriate location as the type of controller  400  and the type of pulse wave generating component are varied. As depicted in the exemplary embodiment the control package  400  is provided as a controller  400  and an at least one pulse wave generating component, in this instance a solenoid  420 . The control package  400  provides a variable timed input to produce a controlled pressure variance or pulse wave within the laminar water flow channel  500 .  
         [0049]     This can be accomplished in any number of ways, in the exemplary embodiment shown, the solenoid  420  “thumps” or strikes the side(s) of the housing  100  to produce the pressure wave within the laminar water flow channel  500 . Additional methods of providing the controlled variable pulse wave within the water flow may be utilized, for example the components of the package can be made to include digital electronic, analog electronic, electromechanical, or mechanical components suitable for producing a controlled input, such as a mechanical striking mechanism with a motor and clocks, an inline water wheel that driven by the incoming water flow, a return drip system that strikes the laminar water flow channel, sonic devices, electromechanical striking devices and similar components that can provide a metered pulse wave to interrupt the laminar jet as an pulse wave generator.  
         [0050]     The control package  400  can comprise additional components. The controller may alternatively be comprised of all solid state components, all electrical components, all mechanical components, or any suitable combination therein to provide the necessary conrolled resonance or “thump” to create the pressure wave on or in the laminar water flow channel  500 . The components may be located in contact with the housing  100  at any position in, on, within, or without the housing that would allow the energetic wave to enter the water channel. Similarly, the components may be located discreetly away from the water jet, for instance if the system is utilizing an ultrasonic device, such that contact with the housing  100  is not necessary to input the energetic wave.  
         [0051]     In the exemplary embodiment shown, the solenoid  420  is controlled by the microprocessor  410  and may be timed to suit a desired application. For instance, the microprocessor  41   0  may time the impulse from the solenoid  420  to music. Additionally, the controller  400  may be controlled by a master controller  7000 , as further shown and described in relation to  FIG. 5 , which controls additional features or accessories in a coordinated water display. The controller may also include a wireless controller or connection, also as shown further in relation to  FIG. 5 .  
         [0052]      FIG. 3A  shows an exemplary embodiment of the instant invention in operation with a segmented tubular flow. The controller  400 , through the pulse wave  760 , interrupts the laminarity of the laminar water jet tube  750 , producing discrete segments of laminar water jet tube  755  while maintaining the continuity of the tube. The timing of the pulses and the length of the jet  750  and the segments  755  can thus be controlled to provide a wide number of variations in the shape and size of the laminar jets. Additionally, the interruptions  760  in the laminar water tube issuing from the jet can result in a pleasing lighting effect, wherein each of the segments  755  provides a refractive and/or reflected concentration of light, similar to a starburst affect. This effect results from refraction and reflection, basically a concentration of light at the point of the pulse wave, that shines the light outward through an interruption  760  in the outer water jacket created by the water tension in forming the laminar flow water tube. This also allows for discrete multicolor segments as the point of concentration or interruption  760  acts as a boundary or interruption in the transmission of light within the tube, thereby permitting the use of different colors within each discrete segmentation  755 .  
         [0053]      FIG. 3B  shows an exemplary embodiment of the instant invention in operation with a segmented columnarized flow. The tube can also be columnarized by conventional methods, such as a diverter or disrupter, or may be columnarized by a prolonged pulse wave to separate the tube into discrete columns  752 . The columns may then be further segmented into discrete segments  755  by the pulse wave  760 . The diversion or columnarization can be coordinated with color changes to provide multiple color columns  752 . Similarly, the segmentation created by the interruptions or pulse waves  760  can be coordinated to provide multiple color segments  755  within the discrete columns  752 .  
         [0054]     The control package  400 , as previously discussed, provides a periodic, controlled protuberance or pulse within the water channel or the laminar flow. This protuberance is an energetic wave that passes through the laminar flow, through the jetting of the laminar flow, and continues as an interruption in the laminarity, producing a controlled “ripple” in the resulting laminar flow tube issuing from the jet. These periodic protuberances are produced to provide controlled interruptions, as seen in  FIGS. 3A and 3B , in the laminarity of the laminar flow tube, in this instance as it exits the laminar water channel  500  at the jet outlet  115 . This produces breaks, as shown, within the laminar out flow or laminar tube or column. In addition to the visual effect of breaking the laminar flow tube that is ejected, known as columnarization, in this case, as shown in  FIG. 3B , the energetic wave can further segment the discrete columns. That is the instant invention can produce discrete pieces of laminar flow tube with or without visible gaps, as seen in  FIGS. 3A and 3B . These interruptions in the laminar flow tube provide a particularly desirable effect when combined with the lighting from lighting tube  170 .  
         [0055]     The lighting tube  170  in the exemplary embodiment shown in  FIG. 1  provides for illumination of the laminar flow tube as it is ejected. The illumination travels within the laminar flow tube like a fiber optic wire, reflecting within the tube and providing a pleasing colored glow. This light is interrupted by the pulse wave portions  760  of the instant invention, preventing light from going beyond the interruption and preventing light in a proceeding segment from going back down the tube to the preceding section. Thus, the lighting and lighting changes within the lighting tube  170  can be coordinated with the controller  400  to provide a seemingly multicolor laminar water jet. This can be provided as a solid or columnar laminar flow water jet. Thus, besides being able to provide the typical columnarization of the laminar flow water jet can be coordinated with segmentation within the columns to provide multi-colored columns, as seen in  FIG. 3B .  
         [0056]      FIG. 4  shows a flow chart of an exemplary embodiment of the method of the instant invention. The steps are provided in this order for this particular embodiment, the order of the steps may be varied to suit other exemplary embodiments without departing from the spirit of the invention. In the exemplary embodiment shown, the method of the instant invention is accomplished by generating a laminar flow within a water channel in conjunction with a pump in step  1000 . In step  2000 , a controller with a control input monitors the input. In step  3000 , an energetic pulse is sent into the laminar flow upon a command from the controller, which can send the command based on a change or signal from the control input. The control input can be for instance a timer or other input. The controller can send the energetic wave via an energetic wave generating component, for instance a solenoid, which imparts the energetic pulse into the water channel to interrupt the laminarity within the water channel. It should however be noted that additional exemplary embodiments may place the input of the energetic pulse closer to the outlet of the laminar flow water jet or external to the laminar flow water jet and are within the spirit of the instant invention.  
         [0057]     In step  4000 , the laminar flow in the water channel is jetted to form a laminar jet column with the interruption imparted by the energetic wave generating component. This is done, for instance, through a jetting nozzle. The laminar jet column is then ejected in step  5000 . Optionally, an additional step, in this instance step  6000  provides for a determination to be made regarding a segment variable. Although it may be accomplished at any time during the process, a change in a segment variable, such as a change in illumination may be conducted in coordination with a signal from the controller in step  7000 . For instance, the light being shone into the column can be changed just after or just before the energetic pulse interruption. Alternatively, no change may be necessary and operations will continue from the beginning of the flow chart. The entire operation is repeated to suit the display.  
         [0058]      FIG. 5  shows a block schematic of the controller. The block schematic diagram shows a controller  400  with an at least one control input  440 , for instance input from a timer or input from an audio translator or similar control input. The controller  400  can also be in communication with pump  75 . An energetic pulse wave generating component  420  is provided, which can be for instance, but is not limited to, a solenoid or any of the devices previously enumerated. The energetic pulse wave generating component  420  generates the controlled pulse wave that creates the interruption, the “ripple”, in the laminar flow within the water channel. The energy pulse generating component  420  communicates with the controller  400  to indicate its status. The controller  400  signals the energy pulse generating component  420  based on the input from the at least one control input  440 . In addition to signaling the energy pulse wave generating component  420 , the microprocessor controller  410  can additionally control lighting system(s)  700 . The lighting system(s)  700  can be for instance be, but are not limited to, conventional incandescent, halogen, fiber optic, LED or similar lighting systems. Similarly, the microprocessor controller can also control an audio system  710  or other components  730 ,  740 ,  750  associated with an overall water feature presentation. These can comprise further water jets  730  or other water features, such as fountains, pop jets, waterfalls, and the like  740 ,  750 . These additional components can be communicated with via hardwired lines or wirelessly, as shown.  
         [0059]     In addition to controller  400 , a master controller  7000  can optionally be provided, shown in shadow. The master controller  7000  can optionally (indicated by the dashed lines) communicate with the controller  400  to control the laminar flow water jet and, through controller  410  or through its own connections with the further components  730 ,  740 ,  750 , additional components in a coordinated water display. This communication can be through hardwire connections or wirelessly.  
         [0060]      FIG. 6  shows an electrical wiring diagram of an exemplary embodiment of the controller. The micro-processor  410  of controller  400  is in communication with at least one solenoid  420  with an optional remote control  437  communicating with it. The power input for the system is provided through transformer  77 , which provides power to the controller. The transformer  77  steps the AC current down, for instance a 110 or 240 AC power input.
