Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to U.S. Provisional Patent Application No. 62/008,661 filed on Jun. 6, 2014 titled “Pipeless Water Jet Assembly” and the disclosure of which is incorporated herein. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to a jet assembly for generating a massaging pulse of water commonly associated with whirlpools, hot tubs, pedicure spas, swimming pools, bathtubs, medical tubs, and other such devices that are commonly subsequently cleaned and/or disinfected prior to subsequent use. 
       BACKGROUND OF THE INVENTION 
       [0003]    It is generally known to provide a jet stream of water in such products as health and swim spas, whirlpools, jet stream exercisers, foot spas, bathtubs, etc. such that the stream of water can provide a massaging effect to the person positioned proximate the outflow of the jet. Such jet producing systems have been in commercial use for decades. However, all of the water jet producing devices in existence today have disadvantages including being difficult and sometimes almost impossible to thoroughly clean and/or disinfect. While it is accepted that diligent adherence to published procedures for cleaning and/or treatment can often maintain a desired level of clarity and sanitary condition of the water associated with such appliances, many such processes are commonly complicated, costly and time consuming such that such cleaning procedures are rarely strictly adhered to and/or followed. 
         [0004]    More aggressive cleaning protocols can require the user or service personnel to disassemble pump and jet assemblies such that disassembly of pump impellers, screens and/or stators, etc, such that the cleaning process takes an inordinate amount of time and associated with the inability to use the respective appliance. Such service and cleaning down time considerations cost commercial users of such devices to lose income as well as endure the expense associated with such services and the intermediate chemical treatments. In the case of consumers, complicated cleaning procedures of piped or even pipe free water jet systems are hardly, if ever, strictly adhered to. Such inattention can result in the collection of the undesired matter in the jet system which is expelled into the user environment upon subsequent operation of the jet system. 
         [0005]    Several actions can be taken in an attempt to overcome the difficulty of sanitation, including the addition of chemicals (e.g., bleach, chlorine, bromine) into the water to help control bacteria growth. Despite such efforts, however, water quality is sometimes still difficult to maintain. For example, bacteria can develop simple defense mechanisms such as the formation of a protective barrier or layer to counter chemical attacks. The destruction of the outer coating or barrier is generally successful with chemicals alone but most often times chemicals are only effective in destroying the outer barrier when used for extended periods of time, sometimes hours. Therefore, the preferred method of eliminating bacteria from jet pumping systems is through mechanical means such as abrasion (e.g., removal with a rag and a chemical cleanser that has anti-bacterial capabilities). 
         [0006]    Unfortunately, many spa devices have intricate and elaborate systems of passages, cavities, orifices and pipes that move water from a pump, through a filtering system, and ultimately to one or more nozzles (e.g., openings) that deliver water back to a basin for re-circulation. In the case of a pedicure basin or whirlpool, the process of cleaning after each use involves draining the water from the system, spraying the basin with an anti-bacterial cleanser, circulating the water for a period of time, discarding the cleaning fluid, rinsing the basin, refilling with fresh water, re-circulating and draining once again. The various pipes and fittings often render it difficult if not impossible to mechanically scrub every component that comes into contact with the circulated water. Further, after a system is drained, some water commonly remains within the piping system, usually in cracks, crevices, and low portions of the circulation loop. For example, the pump itself is usually a sealed unit that may be difficult to completely drain. It is within these areas that bacteria tend to grow the outer barrier coating as a defensive mechanism against attack from anti-bacterial chemicals, especially when the system is not used for extended periods (e.g., overnight, weekends, etc.). Consequently, water quality may be diminished in conventional piped systems that are not effectively cleaned. 
         [0007]    Another consideration to jet system constructions is that the jet streams produced by all systems in existence today rely on a high velocity, low mass flow stream to impart a massaging effect. The jet streams produced are harsh and can become uncomfortable after only a few minutes of use. Generally, people will sit in the jet stream for only a short period of time and then turn the jets off or remove themselves from the stream or, for those systems that include adjustable jets, reduce the velocity of the jet stream to levels that can be tolerated for longer durations. Such actions commonly satisfy the desires of one user to the detriment of the desires of other users. 
         [0008]    The sometimes harsh massaging effect associated with many spa systems is commonly generated by pointing a small number of nozzles (e.g., openings) toward the body of the user. These nozzles are generally connected via pipes and hoses to a single centrifugal pump that produces a very high pressure (20-40 psi) and a relatively low volume of water. Many customers often complain that the jets of water produced in this manner are too rough, in some cases even producing pain or discomfort. Although the jets can be partially closed to reduce the force of the water stream, this also reduces the volume of water communicated from the discrete jets. Consequently, the massage effect is reduced since the jets are often a considerable distance away from the body (e.g., in the walls of the basin). 
         [0009]    U.S. Pat. No. 2,312,524 to Cox discloses one example of a foot bathing device that utilizes foot rests that consist of a disk of heavy wire screening or a perforated plate. This type of system can have several disadvantages including producing unrestricted streams of water. For example. Cox discloses the use of a flat foot rest containing a uniform pattern of openings across the entire foot rest that is not capable of directing the water in any particular direction (e.g., a foot rest that includes a uniform grid pattern across the entire foot rest). 
         [0010]    Therefore, there is a need for jet assembly that generates a desired massage effect and that mitigates some of the sanitation problems disclosed above. Further, it would be advantageous to provide an apparatus that does not require disassembly in order to achieve adequate disinfection. It would be further advantageous to have a device that produced a very large volume of water flow with very little pressure so that the massaging effect would not become uncomfortable after relatively short periods of exposure to same. It would also be advantageous to provide a massaging jet assembly that can be fluidly isolated for the contents of the basin to simplify winterization of such devices. Finally, it would also be advantageous to more efficiently create a pulsation of water so that the cost associated with operation of the water movement or pumping apparatus could be reduced. 
       SUMMARY OF THE INVENTION 
       [0011]    The present invention discloses a water jet pumping apparatus or device that overcomes one or more of the shortcomings discussed above. One aspect of the invention discloses a water jet assembly having a faceplate that defines an inlet and an outlet and a base constructed to cooperate with the faceplate. A diaphragm is disposed between the base and the faceplate and configured to cooperate with the faceplate to be movable between a first position wherein the diaphragm interferes with passage of a fluid through one of the inlet and the outlet and a second position offset from the faceplate to define a volume therebetween. An exciter is connected to the base and configured to excite the diaphragm to move fluid from the inlet to the outlet during operation of the exciter and such that the diaphragm occupies the volume when the exciter is off. 
         [0012]    Another aspect of the invention useable with one or more of the features of the aspects above discloses a water jet assembly that includes a housing that is constructed to cooperate with a faceplate. The faceplate defines a plurality of inlets that are oriented radially about at least one outlet. The water jet assembly includes a diaphragm that is movable between a first position and a second position and disposed between the housing and the faceplate. The diaphragm obstructs the plurality of inlets and the at least one outlet when it is in the first position and defines a fluid passage between the diaphragm and the faceplate that extends between the plurality of inlets and the at least one outlet when the diaphragm is in the second position. An exciter is supported by the housing is configured to oscillate the diaphragm between the first position and the second position to move fluid from the plurality of inlets to the outlet via, the fluid passage during operation of the exciter and such that the diaphragm obstructs the plurality of inlets and the at least one outlet when the exciter is off. 
         [0013]    Another aspect of the invention discloses a method of forming a water jet flow that includes drawing water into a variable volume chamber of a jet assembly and expelling water out of the variable volume chamber of the jet assembly by operation of an exciter. The smallest volume of the chamber is occupied by a diaphragm when the exciter is off such that water is not retained internal to the jet assembly when the jet is not operated. 
         [0014]    Preferably, the water jet apparatus according to the present invention provides a means for pumping fluid while utilizing a torroidal soliton effect. Another feature of the present invention is to provide a means to pump water with a device that does not require disassembly to maintain proper cleaning or a desired sanitation of the jet assembly. Another feature of the present invention is to provide a means to create the effect of pumping large volumes of water without actually pumping large volumes of water. Another feature of the present invention is to provide a means to provide a massaging feel that is greatly improved over current technology. Another feature of the present invention is to force nearly or all of the entrained water out of the jet assembly when not operating. 
         [0015]    Another feature of the present invention provides a means to destroy bacteria that may remain in the pumping mechanism through the use of silver or other suitable alternative plating or antibacterial materials on the internal surfaces associated with the pumping activity. Another feature of the present invention is to provide a water jet apparatus that does not require circulation pipes or pumps between the inlet and the outlet of the discrete jet assemblies. Such a consideration mitigates bacterial problems common to spa and hot tub assemblies that include a plurality of jets whose operation is associated with a primary pump associated with hidden plumbing features. 
         [0016]    Another feature of the present invention is to provide an apparatus that can be properly disinfected after use without physical scrubbing or cleaning and/or without disassembly of the discrete jet flow generating devices. Another feature of the present invention is to provide a spa apparatus that does not have a single continuous elongated flow of water directed into and then out of the respective water jet devices and which can cause undesirable materials to be delivered and/or re-circulated by water and/or air jet systems. Another aspect or feature of the device is to provide a massaging effect that is unlike any other device in use today and which commonly requires high volume and high velocity water flows. 
         [0017]    These and other aspects and features of the present invention will be more fully understood from the following detailed description and the enclosed drawings.

       DETAILED DESCRIPTION 
       [0028]    It is appreciated that, while the disclosed embodiments are illustrated as a jet apparatus designed for bathtubs, spas, whirlpools, hot tubs and the like, the present invention discloses and includes features that have a much wider applicability. For instance, it is appreciated that the present invention is usable with various tub, pool, and/or spa designs which can be adapted for various uses such as hand spas, other body parts, entire bodies, one or multiple persons, etc. Further, the size and relative orientation of the various components and the size of the apparatus can be widely varied. 
         [0029]    It is further appreciated that the particular materials used to construct the exemplary embodiments are also illustrative. Components of the device, assembly, or apparatus can be manufactured from thermoplastic resins such as injection molded high density polyethylene, polypropylene, other polyethylenes, acrylonitrile butadiene styrene (“ABS”), polyurethane, nylon any of a variety of homopolymer plastics, copolymer plastics, plastics with special additives, filled plastics, etc. Also, various molding operations may be used to form these components, such as blow molding, injection or cast molding, rotational molding, etc. In addition, various components of the jet assembly and/or spa apparatus can be manufactured from stamped alloy materials such as steel or aluminum, or other metallic materials. 
         [0030]    Proceeding now to descriptions of the preferred and exemplary embodiments,  FIGS. 1-5  show various views of a water jet device or assembly  10  and a basin, hot tub, bath tub, or spa equipped with multiple water jet assemblies according to one embodiment of the present invention. Although usable in a plurality of environments as alluded to above, jet assembly  10  is configured for use in fluid environments such as basins, pools, whirlpools, hot tubs, bathtubs, spas, and the like, as described further below and as shown in  FIG. 5 . 
         [0031]    Referring to  FIGS. 1-4 , jet assembly  10  includes a faceplate  12  that is constructed to cooperate with a housing or base  14 . Faceplate  12  defines an outlet  13  and a plurality of inlets  15  associated with generating a toroidal shaped water jet stream as disclosed further below. A diaphragm  16  is disposed between faceplate  12  and base  14 . A seal  118  extends about a circumference of diaphragm  16  and is disposed between faceplate  12  and base  14 . A flap assembly or arrangement  20  is disposed between base  14  and diaphragm  16 . Faceplate  12  and base  14  cooperate with one another to define a chamber  22  that is shaped to accommodate motion of diaphragm  16  as disclosed further below. One lateral side of diaphragm  16  is exposed to the working fluid associated with jet assembly  10  whereas the opposite side of diaphragm  16  is fluidly isolated from the working fluid via a circumferential sealed cooperation between diaphragm  16 , faceplate  12 , and base  14 . 
         [0032]    Jet assembly  10  includes an exciter  24  whose operation manipulates the position of diaphragm  16  relative to faceplate  12 . Exciter  24  imparts motion to or oscillates diaphragm  116  to facilitate the generation of the water jet stream. Exciter  24  can be provided in any number of forms such as a solenoid, a piston pump, a linear actuator, a rotational actuator, a speaker coil, etc. It is further appreciated that each respective exciter  24  can be physically connected to a corresponding diaphragm  16  to effectuate the desired movement of the diaphragm or positionally associated therewith such that a vacuum or other pressure signal can be utilized to effectuate motion of diaphragm  26  in response to operation of the respective exciter  24 . 
         [0033]    Jet assembly  10  pumps a very small amount of fluid that travels through the medium, in this case water, as if it was a large pulse of energy, a “wave” if you will. This effect is known in scientific communities as the torroidal soliton effect and was first characterized in mathematics and physics. A soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. Dispersive effects refer to dispersion relations between the frequency and the speed of the waves. The soliton phenomenon was first described by John Scott Russell (1808-1882) who observed a solitary wave in the Union Canal in Scotland. Russell reproduced the phenomenon in a wave tank and named it the “Wave of Translation”. 
         [0034]    In fluid dynamics such waves are commonly referred to as Scott Russell solitary wave or solitons. Such waves are stable, and can travel over very large distances thereby providing a unique advantage in whirlpools, pools, bathtubs, etc. The term “toroidal” or torus refers to the three dimension doughnut shape of the soliton wave as it moves in a generally outward linear direction away from the origin of the soliton wave form or a direction generally aligned with an axis normal to an imaginary plane defined by the faceplate. It is appreciated that the soliton wave form can be provided as any of a ring torus, horn torus, or spindle torus, or other poly sided toroidal shapes for example, by manipulation of shape, size, and construction of the faceplate and/or inlets and outlets associated therewith, and/or via manipulation of the rate and/or amplitude associated with operation of exciter  24  and the diaphragm  16  associated therewith. Regardless of the shape, jet assembly  10  generates a soliton wave that travels in a generally outward directions, indicated by arrows  54  ( FIG. 5 ) normal to the plane associated with faceplate  12  to generate the massaging effect associated with operation of each discrete jet assembly  10 . 
         [0035]    These and other advantages and features of the present invention are accomplished (individually, collectively, or in various subcombinations) as described below. In one embodiment of the invention, a basin  28  shaped to retain a fluid includes one or more holes or openings shaped to provide for the attachment of multiple discrete water jet assemblies  10 —as shown schematically in  FIG. 5 . 
         [0036]    In its simplest form, the exciter  24  associated with each water jet assembly  10  is provided as a piston pump or linear actuator that is configured to control operation of diaphragm  16  relative to a respective faceplate  12  that defines an orificed outlet. To produce the soliton effect, the volume of water displaced by operation of the piston in a unit of time is sized to work in concert with the diameter of the orifice. If the velocity of the water exiting the orifice is too low, the flow will not separate and “roll” into a donut like or toroid shape soliton. When the flow through the orifice is properly configured, a rolling donut of energy forms and that rolling donut soliton wave can travel for long distances without losing the energy in the wave. In this way each water jet assembly  10  can provide for a pleasing pulse of massage with minimal energy input. 
         [0037]    Operation of the piston is tuned to provide a dwell or delay between generation of successive soliton waves after expelling the previous pulse of water such that the retraction associated with operation of the piston does not “suck” the torroidal flow backward and destroy some, and in some cases all, of the energy associated with the respective soliton wave. The inlets  15  and outlet  13  are shaped to mitigate interference between the incoming and outgoing fluid flows. Accordingly, the piston associated with operation of exciter  24  is allowed to dwell at the top of the travel path thereby allowing each discrete soliton wave  30  to move away from the orifice associated with outlet  13 . 
         [0038]    Additionally, retraction of a piston associated with the respective exciter  24  pulls a new pulse of water from the bathing environment into the pumping cavity via retraction of diaphragm  16  relative to inlets  15 . Inlets  15  are dispersed circumferentially about faceplate  12  and radially outboard of outlet  13  to mitigate undesirable sucking of anything other than water into each water jet assembly  10  and degradation of the discrete soliton waves attributable to the incoming water stream. Check valves or flap assembly or arrangement  20  mitigate the ability of water to exit the pumping cavity or area immediately behind faceplate  12  and adjacent diaphragm  16  except through outlets  13 . That is, flap arrangement  20  and diaphragm  16  cooperate with one another such that a fluid path associated with inlets  15  is interrupted prior to interruption of outlet  13  during translation of diaphragm  16  toward an inward facing surface  40  of faceplate  12 . 
         [0039]    Conversely, during intake operation, flap arrangement  20  and diaphragm  16  cooperate with the interior facing surface of faceplate  12  such that obstruction of the fluid path associated with inlets  15  is opened prior to diaphragm  16  achieving a spaced relationship relative to outlet  13 . Such a consideration achieves the desired common fluid flow direction through each jet assembly  10  during operation of the discrete jet assemblies  10 . When not operating, diaphragm  16  cooperates with the inward facing surface  40  of faceplate  12  such that diaphragm  16  occupies the void or flow path associated with the water flow path between inlets  15  and outlet  13  associated with the jet pumping operation. Such a construction mitigates the retention of environment water within the workings of jet assemblies  10  when the jet assemblies are not operated. Preferably, one or more of at least the working fluid exposed surfaces of faceplate  12 , diaphragm  16 , and/or base are coated with a silver layer or other suitable antibacterial material or coating to further mitigate existence or propagation of bacteria growth. 
         [0040]    Referring to  FIGS. 3-5 , it is envisioned that basin  28  can include a plurality of jet assemblies  10 . Although shown as a tub or spa, it is further appreciated that basin  28  can be provided in a variety of shapes and configured to accommodate an entire body or just portions thereof. It is further appreciated that each jet assembly  10  can be constructed to cooperate with basin  28  in a sealed manner. As shown in  FIG. 2B , a wall  27  of basin  28  includes one or more openings configured to slideably receive a respective water jet assembly  10 . A nut  32  or other securing arrangement rotationally cooperates with an external surface  34  of housing or base  14  such that wall  27  of basin  28  can be secured to basin  28  in a sealed manner. It is appreciated that nut  32  could be provided to cooperate with a structure of water jet assembly  10  that is internal or external to basin  28 . It is further appreciated that basin  28  could include a threaded or other interference interface about the perimeter of each opening configured to receive a respective water jet assembly  10  in a sealed manner. It is further appreciated that the sealed interaction between each jet assembly  10  and basin  28  can be provided at an interface between base  14  and faceplate  12  or other structure associated with each discrete jet assembly  10  and basin  28 . It is further appreciated that extraneous securing structures, such as nut  32 , can be configured to cooperate with the respective jet assemblies  10  from directions internal to the basin or external thereto. 
         [0041]    Regardless of the specific mounting arrangement, each jet assembly  10  is connected to a control system  48  configured to control operation of the discrete exciters  24  and the jet assembly  10  associated therewith. Although each jet assembly  10  is fluidly isolated from the other jet assemblies, aside from being exposed to the working fluid associated with basin  28 , each jet assembly  10  is connected to control system  48  by one or more elongated connectors  50 ,  52 , such as wires or pneumatic tubing to communicate the desired operating instructions to the discrete jet assemblies  10  to achieve a desired output or massage action associated with operation of the respective jet assemblies  10 . 
         [0042]    Control system  48  preferably includes a display  56  and one or more inputs  58 ,  60 ,  62 ,  64 ,  66 ,  68  configured to allow a user  70  to generate a desired output or massage affect associated with utilization of basin  28 . Preferably control system  48  allows a limited degree of adjustability associated with the amplitude and/or frequency associated with the generation of the discrete soliton waves  30  during utilization of basin  28 . It is appreciated that control system  48  can also be configured to allow the operation of only selected or desired jet assemblies  10  to satisfy different user preferences. When provided in such a methodology, it is further appreciated that the respective jet assemblies designated as preferably providing no massage effect, default to an “OFF” condition wherein the diaphragm obstructs both the outlet  13  and inlets  15  associated with a discrete jet assembly thereby isolating the internal workings of the same from the operating environment, or be allowed to operate at a frequency and/or an amplitude wherein the discrete jet assembly  10  does not generate a soliton wave  30  having an amplitude perceptible by a user  70 . It should be appreciated that the operation of each discrete jet assembly  10  can be adjusted to manipulate the amplitude and or frequency of the soliton wave  30  such that the wave collapses before impinging on user  70  of basin  28 . Such a consideration allows basin  28  to provide various preferred massaging effects to satisfy preferences specific to different users of basin  28 . 
         [0043]    It should be appreciated that exciter  24  associated with jet assemblies  10  can be provided in a variety of forms configured to generate the oscillated operation of diaphragm  26 . It should be appreciated, from the generally elongated shape, that exciter  24  shown in  FIG. 1  is commonly referred to as a linear actuator that includes a driven element that translates in a direction generally aligned with the elongated shape of the exciter. Understandably, it may periodically be desired, or even necessary, to provide the desired operation of diaphragm  16  in a more compact of alternate configuration to accommodate use of soliton water jet assemblies under various spatial constraints.  FIGS. 6-9  show various views of some such exemplary exciter configurations. 
         [0044]      FIGS. 6 and 7  shown a first exciter drive arrangement  100  according to an alternate embodiment of the present invention. Drive arrangement  100  includes a drive element  102  and a driven element  104 . Drive element  102  is configured to be driven in a rotational direction, indicated by arrow  106 , relative to driven element  104  and a base or housing element  108 . An outward radial surface  110  of drive element  102  includes a chase for groove  112  that extends circumferentially about outward radial surface  110  of drive element  102 . A post  114  extends from a radially inward facing surface  116  of driven element  104  and slideably cooperates with groove  112  defined by drive element  102 . 
         [0045]    An outward radial surface  118  of driven element  104  includes one or more ribs  120 , that slideably cooperate with a respective groove  122  associated with a radially inward facing surface  124  of housing  108 . The slideable cooperation of ribs  120  and grooves  122  facilitates an axially slideable association between driven element  104  and drive element  102  and housing  108 . Groove  112  associated with drive element  102  translates in an axial direction, indicated by arrow  128 , along the circumference of the exterior surface  110  of drive element  102 . During rotation  106  of drive element  102 , the slideable cooperation between post  114  and groove  112  effectuate axial translation  128  of driven element  104  relative to drive element  102  and housing  108  thereby generating linear axial oscillation of driven element  104  in response to rotation  106  of drive element  102 . The linear axial translation  128  of driven element  104  relative to housing  108  and drive element  102  generates the desired oscillation of diaphragm  116 , so as to facilitate sequential generation of multiple soliton waves  30  in response to a rotational input signal associated with rotation  106  of drive element  102 . 
         [0046]      FIGS. 8 and 9  show alternate exciter drive arrangements,  150 ,  200  according to yet other embodiments of the present invention. Each drive arrangement  150 ,  200  includes a drive element  152 ,  202  that is driven in a rotational direction, indicated by arrows  154 ,  204 , respectively, and operatively associated with a driven element  156 ,  206 . Each drive element  152 ,  202  includes a post  158 ,  208  that slideably cooperates with a groove or channel,  160 ,  210  associated with the respective driven element  156 ,  206 . Each channel  160 ,  210  is contoured to generate a linear axial translation, indicated by arrows  162 ,  212  of the respective driven element  156 ,  206  in response to rotation,  154 ,  204  of the respective drive element  152 ,  202 . Respective posts  158 ,  208  are offset in a radial direction relative to the respective axis of rotation,  166 ,  216  of the respective drive element  152 ,  202 , such that the slideable cooperation between posts  158 ,  208  with respective channels,  160 ,  210  effectuate the sequential axial translation,  162 ,  212  of the respective driven element  156 ,  206  and generate the desired oscillation of diaphragm  16  to facilitate sequential generation of solid time waves  30 . 
         [0047]    As compared to the embodiment shown in  FIGS. 6 and 7 , wherein the axis of rotation associated with drive element  102  is generally aligned with the longitudinal displacement axis  128 , it should be appreciated that rotational axes  166 ,  216  associated with the embodiments shown in  FIGS. 8 and 9  are oriented in a crossing direction relative to the axis associated with the longitudinal displacement axis  162 ,  212 , respectively, of the driven element. Such a consideration accommodates those configurations wherein close spatial restrictions reduce the ability to utilize generally elongated exciter orientations, such as that shown in.  FIG. 2 . It is further appreciated that the various embodiment shown in  FIGS. 6-9 , are merely exemplary of various exciter drive arrangements envisioned to be utilized in the generation of soliton waves  30 . It should be further appreciated that the general orientation, shape, and construction of posts  158 ,  208  and channels,  160 ,  210  are merely exemplary and that other configurations, even reverse configurations of the post and channel relative to the drive and driven elements, are envisioned for converting the rotational input associated with operation of respective drive elements  152 ,  202 , to generate the longitudinal axial displacement,  162 ,  212  associated with respective driven elements  156 ,  206 . 
         [0048]    The table below includes the data associated with sequentially generating a plurality of soliton waves  30  according to any of the embodiments described above. The data in each successive right hand column follows the data in the immediately preceding left hand column.  FIG. 11  is a graphical representation of the data presented below.

         [0049]    Referring to  FIG. 11 , a soliton wave  30  associated with the maximum acceleration and velocity data, is generated for each rotation or axial translation of the exciter drive arrangement associated with any of the above embodiments described above. As shown therein, a delay or dwell event  300  is provided immediately after generation of each soliton wave to mitigate detraction from the energy associated with each wave caused by subsequent oscillation of the diaphragm  16  necessary for generation of subsequent soliton waves. It should be appreciated that the physical arrangement and cooperation between the respective elements of any of the exciter drive arrangements described above can be manipulated so as to manipulate the amplitude associated with each solid time wave and the timing associated with subsequent wave generation. Such considerations allow each exciter drive arrangement to be configured to generate a soliton wave having a desired magnitude and sequencing.
