BACKGROUNDMillions of people worldwide participate in the sport of surfing, whether it be more traditional surfing, boogie boarding, stand-up paddle boarding, body surfing, or another style of surfing. It is believed that many more would participate in the sport of surfing if they had a better opportunity to do so. Unfortunately, opportunities for many are limited based on where they live (surfing is predominantly available only in coastal areas, and in some lakes), and the weather conditions that they experience (e.g., cold and windy conditions make surfing much less palatable for most surfers and potential surfers, and certain weather conditions can effectively inhibit the creation of surfable waves). Although wave pools have become more common in recent years as a means to bring waves to a broader audience, existing wave pools and wave pool technology typically do not present many real opportunities for surfing. Thus, it is desired to create an assembly and method for consistently generating waves that may be surfable, and that may be located in any possible destinations.
SUMMARYThe present invention is directed toward a wave generation assembly for generating at least one wave along a water surface of a body of water. In various embodiments, the wave generation assembly includes a drive system and a wave generator. The wave generator is coupled to the drive system. The drive system is configured to move the wave generator between a first position and a second position. The wave generator includes (i) a generator shaft that is engaged by the drive system, and (ii) a generator head that is connected to and extends away from the generator shaft. The generator head includes a proximal end that is connected to the generator shaft and an opposed distal end. The distal end includes at least one wave creating surface. When the wave generator is in the first position, the distal end of the generator head is below the water surface. Additionally, when the wave generator is in the second position, the distal end of the generator head is approximately at the water surface. The at least one wave creating surface displaces water at the water surface when moved from the first position to the second position to generate the at least one wave along the water surface of the body of water. In certain embodiments, the wave generator is configured to generate a plurality of waves along the water surface of the body of water that propagate radially away from the wave generator in multiple directions.
In some embodiments, the drive system is directly coupled to the wave generator. Alternatively, in other embodiments, the drive system is indirectly coupled to the wave generator.

The pivot arm includes a first end and an opposed second end, with the drive system being coupled to the first end of the pivot arm and the wave generator being coupled to the second end of the pivot arm. When the drive system moves the first end of the pivot arm in a first direction, the second end of the pivot arm and the wave generator move in a second direction that is substantially opposite to the first direction to move the wave generator from the first position to the second position.
Additionally, in certain embodiments, the wave generator is substantially centrally positioned within the body of water. In such embodiments, the body of water can be divided into a plurality of sections that extend away from the wave generator, and the wave generator can be configured to generate a plurality of waves along the water surface of the body of water that propagate radially away from the wave generator in each of the plurality of sections.
Further, in some embodiments, the wave generator is positively buoyant.

The design of the wave generation assembly 12 can be varied. As an overview, in various embodiments, the wave generation assembly 12 includes a wave generator 214 (illustrated, for example, in
In certain embodiments, the wave generation assembly 12 can be somewhat centrally positioned within the body of water 10, and can be configured to generate a plurality of waves 16 that propagate radially outwardly away from the wave generator 214 in multiple directions, e.g., toward a perimeter of the body of water 10. It is appreciated that the size and frequency of the waves 16, as well as the specific directions in which the waves 16 travel can be varied depending on the specific requirements of the wave generation assembly 12 and the specific design and features present within the body of water 10. Additionally, the wave generation assembly 12 can include the control system 220, including a processor and/or circuits, that controls the operation and movement of the wave generator 214 and the drive system 218. Stated in another manner, in some embodiments, as provided herein, the control system 220 controls the drive system 218 to move the wave generator 214 along a desired path and in a desired time series.
In certain embodiments, as illustrated in
Additionally, as shown, the platform 22 can be made accessible by one or more pathways 24, e.g., bridges, walkways, etc., that extend over or through a portion of the body of water 10 from a shoreline (not specifically illustrated in
Further, in various embodiments, the wave generation assembly 12 can utilize one or more walls, barriers, reef-creating mechanisms or other features (not shown) positioned within the body of water 10 that can impact and control the size, shape, angle and direction of the waves 16 that are generated by the wave generator 214 as the waves 16 propagate outwardly away from the wave generator 214 through the body of water 10. For example, the wave generation assembly 12 can utilize such features to generate different types and sizes of waves in different directions that are more suitable for different audiences. More particularly, in some embodiments, the wave generation assembly 12 can incorporate the use of a plurality of walls 15, or other types of barriers that are usable to divide the body of water 10 into multiple sections of equal or differing sizes. For example, in certain embodiments, the walls 15 or other barriers can divide the body of water into eight different sections that are each of a comparable size. Alternatively, the walls 15 or other barriers can be used can divide the body of water 10 into greater than eight sections or fewer than eight sections, and the sections can be of similar or differing sizes.
As shown in
It is understood that the wave generation assembly 12 need not be configured, however, to generate different types and sizes of waves. Thus, the illustration of different areas within the body of water 10 for different types of waves/surfers is not intended to be limiting in any manner.
The design of the wave generator 214 can be varied. For example, in certain alternative embodiments, the wave generator 214 can be a plunger-type wave generator, a piston-type wave generator, a piston-type buoy wave generator, a pressurized air-type wave generator, a pumped water-type wave generator, or another suitable type of wave generator. In the embodiment illustrated in
In certain embodiments, the generator shaft 226 is configured and positioned to be engaged, e.g., pushed or pulled, by the drive system 218 during operation of the wave generation assembly 212. Alternatively, in other embodiments, the generator shaft 226 can be rotated or moved in another manner during operation of the wave generation assembly 212.
Additionally, the generator shaft 226 can have any suitable size and shape. For example, in certain embodiments, the generator shaft 226 can have a cross-sectional shape that is substantially circular, rectangular, square, triangular, or another suitable shape.
The size, shape and design of the generator head 228 can be varied depending on the types and sizes of waves 216 to be generated, as well as where the generator head 228 is to be positioned relative to the water surface 210A during operation of the wave generation assembly 212. The generator head 228 is connected to (and/or integrally formed with) and extends away from the generator shaft 226. As illustrated, the generator head 228 includes a proximal end 228A that is connected to the generator shaft 226, and an opposed distal end 228B. Additionally, in this embodiment, the generator head 228 includes at least one wave creating surface 230 at, adjacent to, or near the distal end 228B of the generator head 228. For example, in certain non-exclusive embodiments, the at least one wave creating surface 230 can include a flat, an angled or rounded face, i.e. relative to a body 228C of the generator head 228, that is configured to displace water at or near the water surface 210A.
Further, as noted, the generator head 228 can have any suitable shape. For example, in certain embodiments, the generator head 228 can have a cross-sectional shape that is substantially circular, oval, rectangular, square, trapezoidal, triangular, or another suitable shape.
The generator head 228 and/or the wave generator 214 can be formed from any suitable materials. Additionally, in some embodiments, the generator head 228 and/or the wave generator 214 can be formed so as to have a certain buoyancy (i.e. positively buoyant) within the body of water 10. For example, in some such embodiments, the generator head 228 and/or the wave generator 214 can be formed as a hollow structure to provide the desired buoyancy. Stated in another manner, the wave generator 214 can have a density that is less than the density of the water in which the wave generator 214 is being used. For example, in certain non-exclusive embodiments, the wave generator 214 can have a density that is between approximately zero percent and forty percent less than the density of the water in which the wave generator 214 is being used. Alternatively, the wave generator 214 can have a density that is greater than forty percent less than the density of the water in which the wave generator 214 is being used. As such, the range of difference in density between the wave generator 214 and the water is not intended to be limiting in any manner.
With this design, i.e. with a positively buoyant generator head 228 and/or wave generator 214, when the wave generator 214 is at a depth relative to the water surface 210A below a certain equilibrium point, the buoyancy will tend to drive the wave generator 214 toward the water surface 210A. In some embodiments, this can decrease the energy that may be required by the drive system 218, thus potentially lowering the overall power requirements for the wave generation assembly 212. In one non-exclusive alternative embodiment, the wave generator 214 can be configured to have negative buoyancy, i.e. have a density that is greater than the density of the water in which the wave generator 214 is being used, such that the wave generator 214 would naturally sink within the body of water 10 if no external forces are applied to the wave generator 214.
As provided herein, the drive system 218 is configured to engage the wave generator 214 and to move the wave generator 214 along a desired path so the wave generator 214 can generate the desired waves 216. The design of the drive system 218 can be varied. In the embodiment shown in
As shown, during operation of the wave generation assembly 212, the drive system 218 (illustrated as a box) drives the wave generator 214, e.g., pushes or pulls the generator shaft 226, so that the wave generator 214 moves substantially linearly (and vertically) between a first position (outlined in solid lines) and a second position (outlined in dashed lines). Alternatively, it is recognized that the movement of the wave generator 214 between the first position and the second position can be other than substantially vertical, e.g., movement can be at an angle relative to vertical.
In particular, as the wave generator 214 is moved from the first position to the second position, the at least one wave creating surface 230 pushes and/or displaces the water at or near the water surface 210A so as to generate at least one wave 216 that propagates in a generally outward direction radially away from the wave generator 214. Subsequently, the drive system 218 can be utilized to return the wave generator 214 back to the first position, e.g., by pulling or pushing on the generator shaft 226. The operation can then be repeated as many times as desired, and with a desired frequency, such that each movement from the first position to the second position generates at least one wave 216 that propagates in a generally outward direction radially away from the wave generator 214 along the water surface 210A of the body of water 10.
As illustrated in this embodiment, in the first position, the generator head 228, i.e. the distal end 228B of the generator head 228, is positioned at a distance (ranging from a few centimeters to a couple meters) below the water surface 210A. For example, in some non-exclusive alternative embodiments, the distal end 228B of the generator head 228 can be positioned between approximately five meters and ten meters below the water surface 210A when the wave generator 214 is in the first position. Additionally, in the second position, the generator head 228, i.e. the distal end 228B of the generator head 228, is positioned substantially in line with (approximately at) or just below the water surface 210A, e.g., within between approximately one and ten centimeters of the water surface 210A. Alternatively, the generator head 228 can be positioned in a different manner relative to the water surface 210A in either the first position or the second position. For example, in some non-exclusive alternative embodiments, the generator head 228 can be positioned above the water surface 210A in either the first position or the second position. It is merely required that the at least one wave creating surface 230 is positioned to engage, e.g., push and displace, the water at some time during the movement between the first position and the second position in order to generate the desired waves 216.
It is appreciated that in an embodiment where the distal end 228B of the generator head 228 is positioned between approximately five meters and ten meters below the water surface 210A when the wave generator 214 is in the first position, and where the distal end 228B of the generator head 228 is positioned approximately at the water surface 210A when the wave generator 214 is in the second position, the wave generator 214 can have a movement stroke of between approximately five meters and ten meters along the desired path. Alternatively, the movement stroke of the wave generator 214 between the first position and the second position can be greater than ten meters or less than five meters.
In summary, as noted herein, the drive system 218 is configured to engage the wave generator 214 and to move the wave generator 214 along the desired path, i.e. from the first position to the second position, so the wave generator 214 can generate the desired waves 216.
Additionally, as noted above, the control system 220 can include one or more processors and/or circuits to control the operation and movement of the drive system 218 and the wave generator 214. For example, in certain embodiments, the control system 220 is configured to control the drive system 218 to move the wave generator 214 between the first position and the second position in a desired time series, such that waves 216 are created in desired directions and in a desired frequency.
The generator head 328 again is connected to (and/or integrally formed with) and extends away from the generator shaft 326. Additionally, in this embodiment, as shown in
With this design, somewhat similar to in the previous embodiment, the drive system 218, 718, 918 drives the wave generator 314, e.g., pushes or pulls the generator shaft 326, so that the wave generator 314 moves substantially linearly between the first position and the second position. In particular, as the wave generator 314 is moved from the first position to the second position, the at least one first wave creating surface 330A pushes and/or displaces the water at or near the water surface 310A so as to generate at least one wave 316 that propagates in a generally outward direction radially away from the wave generator 314. Subsequently, after pausing, e.g., for approximately five to fifteen seconds or another suitable amount of time, the drive system 218 can be utilized to move the wave generator 314 from the second position back to the first position, e.g., by pulling or pushing on the generator shaft 326. As the wave generator 314 is moved from the second position back to the first position, the at least one second wave creating surface 330B pushes and/or displaces the water at or near the water surface 310A so as to generate at least one wave 316 that propagates in a generally outward direction radially away from the wave generator 314. The operation can then be repeated as many times as desired, and with a desired frequency, such that each movement from the first position to the second position generates at least one wave 316, and each movement from the second position back to the first position generates at least one wave 316. Thus, during movement in either direction, the wave generator 314 generates at least one wave 316 that propagates in a generally outward direction radially away from the wave generator 314 along the water surface 310A of the body of water 10 (illustrated in
As illustrated in this embodiment, in the first position, the generator head 328, i.e. the distal end 328B of the generator head 328, can be positioned at a distance (ranging from a few centimeters to a couple meters) below the water surface 310A. Additionally, in the second position, the generator head 328, i.e. the proximal end 328A of the generator head 328, (and at least a portion of the generator shaft 326) can be positioned above the water surface 310A. For example, in certain non-exclusive embodiments, the generator head 328 can be positioned from a few centimeters to a couple meters above the water surface 310A when the wave generator 314 is in the second position.
Alternatively, the generator head 328 can be positioned in a different manner relative to the water surface 310A in either the first position or the second position. For example, in some non-exclusive alternative embodiments, the generator head 328 need not specifically break the water surface 310A during movement between the first position and the second position. It is merely required that the at least one first wave creating surface 330A is positioned to engage, e.g., push and displace, the water at or near the water surface 310A at some time during the movement from the first position and the second position, and that the at least one second wave creating surface 330B is positioned to engage, e.g., push and displace, the water at or near the water surface 310A at some time during the movement from the second position and the first position, in order to generate the desired waves 316.
As utilized herein, the terms “first wave creating surface” and “second wave creating surface” are merely for convenience and ease of illustration, and either wave creating surface 330A, 330B can be referred to as a “first wave creating surface” or a “second wave creating surface”.
As shown in this embodiment, the piston 432 moves and/or is driven by a drive system, e.g., the drive system 218 (illustrated in
As illustrated, the first cylinder 434 is positioned with a first (upper) end 434A above the water surface 410A and a second (lower) end 434B below the water surface 410A. Additionally, the first cylinder 434 is positioned at least partially within the second cylinder 436. Further, the second cylinder 436 is positioned substantially fully within the water, i.e. with a top edge 436A that is approximately in line with (e.g., within a few centimeters of) the water surface 410A.
In the first position, the piston 432 is positioned above the water surface 410A, and near the first end 434A of the first cylinder 434. Subsequently, in the second position, the piston 432 is positioned at or preferably below the water surface 410A and near the second end 434B of the first cylinder 434. During operation, the drive system 218, 718, 918 moves or drives the piston 432 down into the first cylinder 434 from the first position to the second position. Such movement of the piston 432 drives water out of the first cylinder 434 and into a lower portion 436B (near a base 436C) of the second cylinder 436. As the water is forced into the lower portion 436B of the second cylinder 436, the base 436C of the second cylinder 436 redirects the water and forces (i.e. drives) the water in a generally upward direction toward the outer edge 436D of the second cylinder 436 outside of the first cylinder 434. In particular, the water is forced into the lower portion 436B of the second cylinder 436 and is subsequently redirected by the base 436C in a generally upward direction toward the outer edge 436D of the second cylinder 436 outside of the first cylinder 434. The water is driven such that it moves upward toward the outer edge 436D of the second cylinder 436 and out of the second cylinder over the top edge 436A of the second cylinder 436 and away from the wave generator 414, i.e. away from the cylinders 434, 436. This movement of the water generates or creates at least one wave 416 that propagates radially away from the wave generator 414 along the water surface 410A.
After the at least one wave 416 has been created, the drive system 218, 718, 918 then moves or drives the piston 432 from the second position back to the first position, which allows water to reenter the second cylinder 436 and the first cylinder 434. The process can then be repeated with the desired frequency to continually generate or create additional waves 416 along the water surface 410A.
As utilized herein, the terms “first cylinder” and “second cylinder” are merely for convenience and ease of illustration, and either cylinder 434, 436 can be referred to as a “first cylinder” or a “second cylinder”. Additionally, the terms “first end” and “second end” are also used merely for convenience and ease of illustration, and either end 434A, 434B can be referred to as a “first end” or a “second end” of the first cylinder 434.
As shown in this embodiment, the piston 532 moves and/or is driven by a drive system, e.g., the drive system 218 (illustrated in
In the first position, the piston 532 is positioned near the second end 534B of the cylinder 534. Stated in another manner, in some embodiments, the piston 532 can be positioned between approximately five meters and fifteen meters below the water surface 510A when the piston 532 is in the first position. Subsequently, in the second position, the piston 532 is positioned near the first end 534A of the cylinder 534. Stated in another manner, in certain embodiments, the piston 532 can be positioned at, adjacent to, near or just below (e.g., within between approximately one and ten centimeters of) the water surface 510A when the piston 532 is in the second position.
During operation, the drive system 218, 718, 918 moves or drives the piston 532 up within the cylinder 534 from the first position to the second position. Such movement of the piston 532 drives water out of the cylinder 534, with water being expelled out of the first end 534A of the cylinder 534, and away from the wave generator 514, i.e. away from the cylinder 534. Such movement of the water thus generates or creates the at least one wave 516 that propagates radially away from the wave generator 514 along the water surface 510A.
After the at least one wave 516 has been created, the drive system 218, 718, 918 then moves or drives the piston 532 from the second position back to the first position, which allows water to reenter the cylinder 534. The process can then be repeated with the desired frequency to continually generate or create additional waves 516 along the water surface 510A.
As shown, the piston 632 moves and/or is driven by a drive system, e.g., the drive system 218 (illustrated in
In the first position, the piston 632 is positioned above the water surface 610A, and near the first end 634A of the first cylinder 634. Subsequently, in the second position, the piston 632 is positioned at or preferably below the water surface 610A and near the second end 634B of the first cylinder 634. During operation, the drive system 218, 718, 918 moves or drives the piston 632 down into the first cylinder 634 from the first position to the second position. This movement of the piston 632 drives water out of the first cylinder 634 and into the lower portion 636B (near a base 636C) of the second cylinder 636. As the water is forced into the lower portion 636B of the second cylinder 636, the base 636C of the second cylinder 636 redirects the water and forces (i.e. drives) the water in a generally upward direction toward the outer edge 636D of the second cylinder 636 outside of the first cylinder 634. In particular, the water is forced into the lower portion 636B of the second cylinder 636 and is subsequently redirected by the base 636C in a generally upward direction toward the outer edge 636D of the second cylinder 636 outside of the first cylinder 634. The water is driven such that it moves upward toward the outer edge 636D of the second cylinder 636 and out of the second cylinder through the at least one aperture 638 and away from the wave generator 614, i.e. away from the cylinders 634, 636. This movement of the water generates or creates at least one wave 616 that propagates radially away from the wave generator 614 along the water surface 610A.
After the at least one wave 616 has been created, the drive system 218 then moves or drives the piston 632 from the second position back to the first position, which allows water to reenter the second cylinder 636 and the first cylinder 634. The process can then be repeated with the desired frequency to continually generate or create additional waves 616 along the water surface 610A.
In certain embodiments, the pivot arm 740 can be substantially rectangular bar-shaped, and the pivot arm 740 can be movably, e.g., pivotally, coupled to the pivot support 742 at a pivot point 744. As illustrated, the pivot point 744 can be substantially centrally located along the length of the pivot arm 740. Alternatively, the pivot point 744 can be other than substantially centrally located along the length of the pivot arm 740. Still alternatively, the pivot arm 740 can have another suitable design or another suitable shape.
Additionally, as shown, the drive system 718 is coupled to the pivot arm 740 at or near a first end 740A of the pivot arm 740, and the wave generator 714 is coupled to the pivot arm 740 at or near a second end 740B of the pivot arm 740. With this design, as the drive system 718 moves, pushes or pulls the first end 740A of the pivot arm 740 in a generally upward direction, the pivot arm 740 pivots about the pivot point 744 so the second end 740B pivots down and thus moves or drives the wave generator 714 in a generally downward (vertical) direction, i.e. from the first position to the second position. Conversely, as the drive system 718 moves, pulls or pushes the first end 740A of the pivot arm 740 in a generally downward direction, the pivot arm 740 pivots about the pivot point 744 so the second end 740B pivots up and thus moves or drives the wave generator 714 in a generally upward (vertical) direction, i.e. from the second position back to the first position. As illustrated with the embodiments discussed in detail above, the up and down movement of the wave generator 714 generates or creates at least one wave 716 along the water surface 710A.
As utilized herein, the terms “first end” and “second end” are merely for convenience and ease of illustration, and either end 740A, 740B can be referred to as a “first end” or a “second end” of the pivot arm 740.
As provided herein, the plurality of movable barriers 850 can be used to regulate the wave energy, and thus the size of the waves, from the wave generator 814 to the surf bays, e.g., the “Advanced Bay”, “Intermediate Bay”, “Family Beginner”, “Boogie Board” as shown in the body of water 10 in
It is appreciated that the movable barriers 850 can be positioned to block all or part or none of the wave energy from the wave generator 814 that is propagating away from the wave generator 814 in any direction. For example, if the movable barriers 850 are positioned to block all of the wave energy from the wave generator 814 in any given direction, waves will be inhibited from propagating along the water surface 810A in that direction.
Additionally, in some embodiments, the movable barriers 850 can also be used to isolate (and seal) the wave generator 814 from the body of water 10 to allow the removal of water from immediately adjacent to the wave generator 814 for dry access to the wave generator 814, e.g., for maintenance purposes.
The design of movable barriers 850 can be varied. For example, in certain non-exclusive embodiments, the movable barriers 850 can include wheeled or slide gates whose movement can be guided, e.g., substantially vertically, away from or toward the water surface 810A to selectively allow or inhibit wave energy from the wave generator 814 to move into the surf bays. Alternatively, the movable barriers 850 can have a different design and/or can be guided to move in a different manner.
Additionally, the number of movable barriers 850 can also be varied. For example, as shown in
As shown in
Additionally, as illustrated, the drive system 918 is coupled to the pivot arm 940 at or near the first end 940A, and the wave generator 914 is coupled to the pivot arm 940 at or near the second end 940B. With this design, similar to the embodiment shown in
During use of the wave generation assembly 912, the piston 964 of the drive system 918 is driven substantially linearly (and vertically) within the cylinder 962. In particular, movement of the piston 964 in a generally upward direction within the cylinder 962 pushes or pulls the extension arm 960 in a similar upward direction such that the pivot arm 940 will pivot about the pivot point 944, e.g., in a counterclockwise direction in this example. This pivoting of the pivot arm 940, as noted, moves and/or drives the wave generator 914 in a generally downward direction so that the wave generator 914 engages and displaces water relative to the water surface 910A as the wave generator 914 moves from the first position to the second position. Thus, the wave generator 914 generates or creates the at least one wave 916 along the water surface 910A. Conversely, movement of the piston 964 in a generally downward direction within the cylinder 962 pulls or pushes the extension arm 960 in a similar downward direction such that the pivot arm 940 will pivot about the pivot point 944, e.g., in a clockwise direction in this example. This pivoting of the pivot arm 940, as noted, moves and/or drives the wave generator 914 in a generally upward direction so that the wave generator 914 moves from the second position back to the first position.
As illustrated in this embodiment, in the first position, the generator head 928, i.e. the distal end 928B of the generator head 928, is positioned at a distance (ranging from a few centimeters to a few meters) below the water surface 910A. For example, in some non-exclusive alternative embodiments, the distal end 928B of the generator head 928 can be positioned between approximately five meters and ten meters below the water surface 910A when the wave generator 914 is in the first position. Additionally, in the second position, the generator head 928 is positioned substantially in line with (approximately at) or just below the water surface 910A, e.g., within between approximately one and ten centimeters of the water surface 910A. Further, in certain embodiments, the generator head 928 can be positioned and moved such that the generator head 928 does not break the water surface 910A during movement between the first position and the second position. Alternatively, the generator head 928 can be positioned in a different manner relative to the water surface 910A in either the first position or the second position. For example, in some non-exclusive alternative embodiments, the generator head 928 can be positioned above the water surface 910A in either the first position or the second position. It is merely required that the generator head 928 is positioned to engage, e.g., push and displace, water relative to the water surface 910A during the movement between the first position and the second position in order to generate the desired waves 916.
Additionally, as shown, in certain embodiments, the generator head 928 can be guided in its movement between the first position and the second position. For example, in one embodiment, the generator head 928 can be positioned to move within a chamber 966 that is defined by a guide frame 968 that is positioned within the water. With such design, the generator head 928 of the wave generator 914 is better able to move in the desired generally vertical direction relative to the water surface 910A between the first position and the second position.
In certain embodiments, as noted above, the wave generator 914 can be configured as a buoy that has a positive buoyancy, i.e. with a density that is less than the density of the water, that tends to force the wave generator 914 toward the water surface 910A when the wave generator 914 is below the water surface 910A (or below a certain equilibrium point relative to the water surface 910A). Alternatively, the wave generator 914 can have another suitable design.
Additionally, as shown in
It is understood that although a number of different embodiments of the wave generation assembly 12 have been illustrated and described herein, one or more features of any one embodiment can be combined with one or more features of one or more of the other embodiments, provided that such combination satisfies the intent of the present invention.
