Description

TECHNICAL FIELD

[0001] The present invention relates generally to an audio equipment stand optimized to minimize a noise floor having a specific asymmetric arrangement of a plurality of mounting cradles and their corresponding compression members. BACKGROUND

[0002] An audio noise floor is a measure of the signal produced by the sum of all noise sources and undesired signals in a measurement system, where noise is defined as any signal other than the signal being monitored. In an audio system, the noise floor refers to the amount of sound that an object naturally produces when no signal is passing through it, measured in decibels. A decibel (dB) is a unit used to express the ratio of two physical quantities, such as the relative loudness of a sound. One decibel is equal to 10 times the common logarithm of the power ratio. For example, a 60 decibel sound (such as normal speech) is 10 to the sixth power (i.e., 106 or 1,000,000) times more intense than a sound that is barely perceptible (such as a faint whisper). In a complete system, the noise floor is the sum of all the noise produced by the individual objects in a resting state.

[0003] An incident wave is a wave that is approaching a boundary (e.g., a structure) but has not yet reached the boundary. A reflected wave is a wave that, after interacting with the boundary, moves away from the boundary in the same medium as the incident wave. A transmitted wave moves away from the boundary on the other side of the boundary from the incident wave (i.e., the wave’s travel through the remainder of the structure). If the frequency of the wave matches the natural frequency of the structure, the incident wave reaching the structure also causes resonance.

[0004] A natural frequency is the frequency or rate at which an object naturally vibrates. When an incident wave (also referred to as a signal) reaches an object, and the frequency of the incident wave equals or approaches the natural frequency of the object, the result is vibrations of increased amplitude at the natural frequency of the object. These resulting vibrations are referred to as resonance.

[0005] Generally speaking, the greater the mass of a structure, the lower the natural frequency. If damping is increased, the amplitude of the vibrations will decrease, but there will be a wider range of responses. When the entire object vibrates, it tends to vibrate about the center of mass of the object.

[0006] It should be noted that a signal with a frequency lower than the natural frequency of a structure will pass through or transmit through the structure. As noted above, the present invention seeks to minimize the resonance of unwanted audio signals, otherwise known as the noise floor. This is accomplished by increasing the natural frequency of the structure by increasing the stiffness of the structure.

[0007] Generally, stiffness is the ability of a structure to resist elastic deformation. Many solutions to increase the stiffness of a structure are achieved by adding more structural elements (such as beams) to an existing structure. In many rough applications, this generally achieves the goal of increasing stiffness, however, in the field of audio devices and other systems related to vibration, simply adding additional structural elements can adversely affect the noise floor of the overall structure, as the additional structural elements have their own inherent frequencies.

[0008] A Cartesian coordinate system in a plane is a coordinate system in which each point is uniquely identified by a pair of numerical coordinates, which are the signed distances from the two fixed perpendicular oriented lines, measured in the same length units. The Cartesian plane, also called the coordinate plane, is formed by the intersection of two perpendicular axes, the "x-axis" and "y-axis". There are four quadrants in the Cartesian plane. The signs of the coordinates in each quadrant are given in the form (x, y): first quadrant (+, +), second quadrant (-, +), third quadrant (-, -), and fourth quadrant (+, -).

[0009] Compression members are structural elements that are pushed together or carry loads; they are subjected to axial compressive forces.

[0010] When an incident wave reaches a structure, it tends to displace the structure to a position of greater resistance to vibration, i.e., with high stiffness at the maximum amplitude of the incident wave.

[0011] The force applied to a mass m in a structure is proportional to the amount "x" that the structure is stretched from its rest position. The stretched position corresponds to the amplitude. The proportionality constant k is the stiffness of the structure, with units of force / distance (e.g., lbf / in or N / m). The negative sign indicates that the force of the structure is always opposite the direction of motion of the mass:

[0012] F S = -kx

[0013] Newton's second law of motion states, "The change of motion of a body is proportional to the force impressed; and is in the direction of the impressed force." In other words, the sum of the forces produced by masses is proportional to the acceleration of that mass.

[0014]

[0015] where F is force, a is linear acceleration, and m is mass.

[0016] The moment of inertia of a mass is commonly denoted by I and measures the extent to which a body resists a change in rotational speed about an axis and is analogous to mass m in Newton's second law. The units of moment of inertia are mass x length 2 . The second law for rotation is algebraically expressed as:

[0017] τ = Ia

[0018] where τ is the torque, I is the moment of mass inertia, and a is the angular acceleration.

[0019] A torque is created when a force F is applied perpendicular to a distance r from the axis of rotation. The units of angular acceleration a must be radians per second squared (radians are technically unitless); this can be obtained by dividing the linear acceleration a by the distance r from the axis of rotation. These terms are expressed algebraically as:

[0020] τ = Fr

[0021] Considering that force is equal to mass times acceleration:

[0022] τ = mar

[0023]

[0024] Substituting both of these into Newton's second law for rotation gives:

[0025]

[0026] The general equation for the inertia of a point mass is therefore defined as:

[0027] I = mr 2

[0028] Using continuous integration, it can be seen that the deflection is inversely proportional to EI A , where E is the modulus of elasticity of the material around the axis of rotation. Here, I A represents the moment of area, the area is the cross section and is normal to the axis of rotation, which is different from the units of the moment of mass inertia, but still represents the resistance of the object to angular acceleration.

[0029] In a structure with two parallel axes of rotation, such as a kitchen table with four legs (the tabletop is in the x-z plane), which is subjected to a force from the left (x direction), the legs (y direction) tend to rotate around their respective axes of rotation (both in the z direction) by a few degrees until the structure reaches a position of maximum resistance to the force. However, shifting these axes of rotation in such a way that they are no longer parallel to each other significantly reduces the degree of rotation of the table legs. Therefore, the shift of the axes of rotation increases the moment of inertia.

[0030] Since the deflection is inversely proportional to the product EI A , increasing any of these variables will reduce the amount of deflection in the stiffness test. Deflection is inversely proportional to stiffness. Therefore, increasing the inertia also results in an increase in stiffness.

[0031] The force of the structure in a simple system is the dominant term; therefore, the other terms can be neglected. Thus:

[0032] ∑F = F S

[0033]

[0034] This results in an ordinary differential equation (ODE (1)):

[0035]

[0036] The above ODE (1) has a solution:

[0037] x(t) = A cos(2πf n t)

[0038] This ODE (1) describes the displacement of the center of mass of a given structure over time, if that structure is initially “stretched” or displaced, where A is the amplitude, “f n ” is the undamped natural frequency. In simple systems, the undamped natural frequency is defined as:

[0039]

[0040] Thus, the stiffness k of a structure is inversely proportional to the square of the undamped natural frequency of the structure, and the mass m of a structure is inversely proportional to the square of the undamped natural frequency of the structure.

[0041] The above system is ideal, undamped, and free of external forces affecting the structure. Real-world systems are non-ideal, damped, and often subjected to external forces. Damping here refers to the ability of a structure to dissipate vibrations over time. The resistance of a system to motion is proportional to the velocity of the mass. The damping force D is defined as:

[0042]

[0043] where R is a proportionality constant, called the damping coefficient. The above ODE (1) equals zero because there are no external forces, meaning f(t) = 0. An input force means f(t) ≠ 0. This input force can take many forms, including an oscillatory force described below.

[0044] Again using Newton’s second law, the resulting ODE (2) is:

[0045]

[0046] An oscillatory force, such as one that opposes vibration, can be represented as:

[0047] f(t) = a sin(ωt) + b cos(ωt)

[0048] Where a and b are constants, and ω is the angular frequency of the applied oscillation. In other words, ω is the angular frequency of the incident wave.

[0049] The above ODE(2) has a solution:

[0050]

[0051] S=α±βi

[0052] x(t)=e αt (Asin(βt)+Bcos(βt))

[0053] Here, S is an auxiliary equation used to derive the solution, α represents a real number, and β represents the corresponding value added to the imaginary term, which together equal S.

[0054] R 2 -4mk>0 (or R) 2 >4mk), which produces a complementary function (transient) without oscillation. This is what is called a highly damped system.

[0055] When R 2 When -4mk < 0, there will be an imaginary term β. This means that the damping coefficient is less than 4 times the product of mass and stiffness, or R. 2 <4mk. This produces a sinusoidal transient modulated by purely exponential decay, also known as a slightly damped system. Graphically, it can be seen that the peaks decrease over time. These peaks represent the structure initially displaced from its rest position by an input force, then oscillating with increasingly smaller amplitudes until it returns to its original rest position.

[0056] The aforementioned lightly damped system can be achieved through a system with high quality and relatively low stiffness. However, if the lightly damped system is created to facilitate disassembly, transportation, and reassembly, and to maintain low quality for the other reasons mentioned above, then stiffness must be the dominant factor.

[0057] Furthermore, inertia is the resistance of an object to angular acceleration, and for a point mass, it is defined as mass multiplied by the square of the distance from the axis of rotation. This invention requires high inertia. If the intended design of the structure is to increase inertia while maintaining low mass, then the distance from the axis of rotation must be increased.

[0058] Therefore, there has long been a need for an instrument with a simple, ingenious structure and a high natural frequency, which is a result of high stiffness without harmfully increasing mass. More specifically, there has long been a need for an audio device bracket optimized to minimize the noise floor.

[0059] Furthermore, there has long been a need for equipment with high inertia, which arises from the increased distance from the axis of rotation. More specifically, there has long been a need for a storage support with an intentionally non-parallel axis of rotation to increase structural rigidity. Summary of the Invention

[0089] Furthermore, it should be understood that this disclosure is not limited to the specific methods, materials, and modifications described, and therefore can certainly be changed. It should also be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to limit the scope of the claims.

[0090] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It should be understood that any methods, apparatus, or materials similar or equivalent to those described herein may be used in the practice or testing of the exemplary embodiments.

[0091] It should be understood that the term "generally" is synonymous with terms such as "almost," "nearly," "about," "approximately," "approximately," "close to," "basically," "about," or "around," and these terms may be used interchangeably as they appear in the specification and claims. It should be understood that the term "near" is synonymous with terms such as "close to," "nearby," "adjacent," "adjacent," "nearby," "adjacent," and these terms may be used interchangeably when they appear in the specification and claims.

[0092] It should be understood that, unless otherwise stated, the use of “or” in this application is relative to a “non-exclusive” arrangement. For example, when saying “item x is A or B”, it can be understood that this may mean one of the following: (1) item x is only one or the other of A and B; (2) item x is both A and B. In other words, the word “or” is not used to define an “exclusive OR” arrangement. For example, an “exclusive OR” arrangement stating “item x is A or B” would require that x can only be one of A and B. Furthermore, as used herein, “and / or” is intended to be a grammatical conjunction used to indicate that one or more elements or conditions may be included or appear. For example, an apparatus including a first element, a second element, and / or a third element is intended to be constructed in any of the following structural arrangements: an apparatus including a first element; an apparatus including a second element; an apparatus including a third element; an apparatus including a first element and a second element; an apparatus including a first element and a third element; an apparatus including a first element, a second element, and a third element; or an apparatus including a second element and a third element.

[0093] It should also be understood that the examples provided herein, ending with “etc.,” should be interpreted as feasible alternatives within the scope of the named examples, and therefore the unnamed examples will be clear to those skilled in the art.

[0094] Furthermore, as used herein, the phrases “comprising at least one” and “including at least one” in conjunction with a system or element are intended to indicate that the system or element includes one or more elements listed following the phrase. For example, an apparatus comprising at least one first element, a second element, and / or a third element is intended to be configured in any of the following structural arrangements: an apparatus comprising a first element; an apparatus comprising a second element; an apparatus comprising a third element; an apparatus comprising a first element and a second element; an apparatus comprising a first element and a third element; an apparatus comprising a first element, a second element, and a third element; or an apparatus comprising a second element and a third element. When the phrase “for at least one” is used herein, it is intended to be interpreted similarly.

[0095] It should be understood that the illustrated embodiments are merely one of many possible embodiments of the claimed invention. It should also be understood that directional adjectives, such as “up,” “down,” “right,” “left,” and similar variations, should be interpreted in light of the accompanying drawings and are intended to be exemplary.

[0096] It should also be understood that the term “centroid” used in this paper, especially in relation to the term “centroid” when referring to holes, is defined as follows: the centroid of a hole is defined as being the same as the centroid of an object that completely fills the hole, wherein the centroid of an object is defined as the center of the mass of the object, wherein the object has a uniform density.

[0097] It should be noted that the term "constrained layer damping plate" refers to mechanical engineering techniques used to suppress vibrations, where "plate" encompasses these vibration-suppressing properties. Typically, constrained layer damping components are composed of viscoelastic or other damping materials, such as rubber, polyurethane, polyvinyl chloride (PVC), etc., and are sandwiched between two rigid or stiff materials that themselves lack sufficient damping.

[0098] It should also be noted that the terms “board” and “shelf” are essentially synonymous and can be used interchangeably in this article.

[0099] It should be noted that the figure labels follow the format "ab.cd", where the number in the "ab" field indicates the greater plurality to which the part belongs; the number in the "c" field indicates the level at which the part is removably fixed, starting from 0 and increasing accordingly with the height of each shelf; the number in the "d" field indicates the position at which the part is removably fixed, starting from 1 in the upper right corner from a top view, and proceeding counterclockwise (when viewed from the top of the equipment), increasing by 1 at each vertex. For example, 19.12 is the mounting bracket ( 19 .12), its position from the top left (19.1) in the top-view perspective. 2 It is removably fixed to the first layer (19). 1 2) Above, compression member 15.24 belongs to multiple compression members ( 15 .24), its position from the lower right of the top view (15.2) 4 It can be removably fixed to the second layer (15). 2 4) Above.

[0100] Now take a look at the attached image. Figure 1 This is a perspective view of an audio equipment bracket 10. The audio equipment bracket 10 typically includes: apex legs 50, shelves 13, mounting brackets 19 fixed to the underside of each shelf 13, end caps 28, and compression members 15, wherein each of the plurality of compression members 15 is arranged to engage two corresponding mounting brackets 19, each apex leg 50 is arranged to engage one corresponding mounting bracket 19, and each end cap is arranged to engage one corresponding mounting bracket 19.

The third-tier mounting bracket at the second position 19.32 is also removably fixed to the third-tier shelf 13.3 via the third-tier mounting hole at the second position 29.32. The third-tier mounting bracket at the third position 19.33 is also removably fixed to the third-tier shelf 13.3 via the third-tier mounting hole at the third position 29.33.

[0116] The following description should be based on Figures 4 to 8B To understand. Figure 4 This is a top-down perspective view of the audio equipment bracket 10 from AA's point of view. Figure 5 This is a bottom view of the audio equipment bracket 10.Figure 6 This is a front sectional view of the compression component 20 obtained from the DD perspective. Figure 7A This is a perspective view of type 1 mounting bracket 31. Figure 7B This is a perspective view of type 3 mounting bracket 33. Figure 8A This is a top perspective view of type 3 mounting bracket 33. Figure 8B This is a sectional view of type 3 mounting bracket 33 obtained from the EE perspective.

[0117] The third-level shelf 13.3 has a perimeter 35. Each of the plurality of mounting brackets 19 has one of a plurality of mounting centroids 14 and one of a plurality of compression centroids 16. Each of the plurality of mounting brackets 19 has a mounting portion 17 and a compression portion 18. Each mounting portion 17 has one of a plurality of mounting centroids. When the mounting brackets 19 are fixed to their respective mounting positions 47, the vertex is the mounting centroid 14, which belongs to the first polygon 11.

[0118] The vertices of the first polygon 11 are located at the third-level mounting centroid at the first position 14.31, the third-level mounting centroid at the second position 14.32, the third-level mounting centroid at the third position 14.33, and the third-level mounting centroid at the fourth position 14.34.

[0119] Each of the plurality of compressed centroids 16 defines a vertex belonging to the second polygon 12. The vertices of the second polygon 12 are located at the third-level compressed centroid at the first position 16.31, the third-level compressed centroid at the second position 16.32, the third-level compressed centroid at the third position 16.33, and the third-level compressed centroid at the fourth position 16.34.

[0120] Each rotational mounting axis 61 consists of a line segment that spans from one mounting centroid 14 on the outer periphery of the first polygon 11 to another mounting centroid 14 (e.g., a line segment formed from the third-level mounting centroid at the first position 14.31 to the third-level mounting centroid at the fourth position 14.34, etc.). Each rotational mounting axis 61 is orthogonal to the two mounting centroid axes 14' that intersect at their respective mounting centroids 14.

[0121] Each rotational compression axis 62 consists of a line segment from one compression centroid 16 to another on the outer periphery of the second polygon 12 (e.g., a line segment formed from the third-level compression centroid at the first position 16.31 to the third-level compression centroid at the fourth position 16.34, etc.). Each rotational mounting axis 61 is orthogonal to the two compression centroid axes 16' that intersect at their respective compression centroids 16.

[0122] In its current embodiment, each rotary compression axis is not parallel to its corresponding rotary mounting axis. In other embodiments, at least one rotary compression axis is not parallel to its corresponding rotary mounting axis.

[0123] In its current embodiment, two rotational mounting axes are parallel and orthogonal to two other rotational mounting axes, making the first polygon rectangular. In its current embodiment, none of the rotational compression axes are parallel to each other, making the second polygon not rectangular. If one force causes two compression members to rotate about one rotational compression axis, and another force causes two different compression members to rotate about another rotational compression axis, then the structure will be more resistant to these rotations compared to the case where the rotational compression axes are parallel.

[0124] In the current embodiment, the first polygon 11 is close to a rectangle (if not exactly a rectangle). In the current embodiment, the second polygon 12 is not rectangular because the angle generated at the third-level compressed centroid at the first position 16.31 is an obtuse angle. It should be noted that the angle referred to at a vertex is an angle formed by line segments, one generated by the corresponding vertex and the nearest clockwise vertex, and the other generated by the corresponding vertex and the nearest counterclockwise vertex.

[0125] In its current embodiment, the first polygon 11 may include a shape formed by the vertices of the third-level mounting centroid at the first position 14.31, the third-level mounting centroid at the second position 14.32, the third-level mounting centroid at the third position 14.33, and the third-level mounting centroid at the fourth position 14.34.

[0126] In its current embodiment, the second polygon 12 may include a shape formed by the vertices of the third-level compressed centroid at the first position 16.31, the third-level compressed centroid at the second position 16.32, the third-level compressed centroid at the third position 16.33, and the third-level compressed centroid at the fourth position 16.34.

[0127] In its current embodiment, the shapes formed by the plurality of mounting centroids 14 at the first level 91, the plurality of mounting centroids 14 at the second level 92, and the plurality of mounting centroids 14 at the third level 93 are substantially the same. Therefore, the first polygon 11 can be determined by the plurality of mounting centroids 14 on the first level 91, the second level 92, or the third level 93.

[0128] In its current embodiment, the shapes formed by the plurality of compression centroids 16 at the first level 91, the plurality of compression centroids 16 at the second level 92, and the plurality of compression centroids 16 at the third level 93 are substantially the same. Therefore, the second polygon 12 can be determined by the plurality of compression centroids 16 on the first level 91, the second level 92, or the third level 93. Compression centroid axis 16' shows the overall axis on which the compression centroids 16 of each level's mounting bracket 19 will fall. Mounting axis 14' shows the overall axis on which the mounting centroids 14 of each level's mounting bracket 19 will fall.

[0129] The shelf-adjacent surface 36 abuts the shelf at a perimeter 35. In the current embodiment, the dividing line 37 separates the mounting portion 17 from the compression portion 18.

[0130] Figure 6 A cross-sectional view obtained from a frontal viewpoint DD is shown, showing that the end cap 28 abuts one of a plurality of mounting brackets at the first radially inward surface 21, the second radially inward surface 22 and the third radially inward surface 23.

[0131] Each vertex foot 50 includes a first radially outward surface 41, a fourth radially outward surface 44, a tapered end 45, and a female end 27, the female end further including a third radially inward surface 23, a fourth axial surface 54, and a tapered receiving member 46.

[0132] Each end cap 28 has a fifth axial surface 55 and a male end 25, the male end including a first axial surface 51, a second radially outward surface 42, a third radially outward surface 43 and a tenon end 26.

[0133] Each compression member 15 includes a first radially outward surface 41 and a female end 27, the female end including a third radially inward surface 23, a fourth axial surface 54, and a tapered receiving member 46. Furthermore, each of the plurality of compression members 15 has a male end 25, the male end including a first axial surface 51, a second radially outward surface 42, a third radially outward surface 43, and a tenon end 26.

[0134] Each mounting bracket 19 has a compression hole 30, which includes a first radially inward surface 21, a second radially inward surface 22, a fourth radially inward surface 24, a second axial surface 52, and a third axial surface 53.

[0135] The following description should be based on Figures 9A to 9D . Figure 9A This is a top perspective view of type 3 mounting bracket 33. Figure 9B This is a top perspective view of type 1 mounting bracket 31. Figure 9C This is a top perspective view of type 4 mounting bracket 34. Figure 9DThis is a top perspective view of type 2 mounting bracket 32.

[0136] Boundary line 37 is parallel to the x-axis 38. Boundary line 37 and x-axis 38 are substantially perpendicular to the y-axis 39. The y-axis 39 and x-axis 38 intersect at the origin 40. These terms are borrowed from their mathematical descriptions; however, they do not imply adherence to every mathematical constraint or principle, and are used here only as general descriptors. Type 1 mounting bracket 31 has a compressed centroid 16 in the first quadrant defined in a Cartesian coordinate system. Type 2 mounting bracket 32 ​​has a compressed centroid 16 in the second quadrant defined in a Cartesian coordinate system. Type 3 mounting bracket 33 has a compressed centroid 16 in the third quadrant defined in a Cartesian coordinate system. Type 4 mounting bracket 34 has a compressed centroid 16 in the fourth quadrant defined in a Cartesian coordinate system.

[0137] The following description should be based on Figures 10A to 10B . Figure 10A This is a side view of type 1 mounting bracket 31. Figure 10B yes Figure 10A The perspective view of the Type 1 mounting bracket 31 shown.

[0138] The compression orifice 30 is a three-dimensional boundary. The compression mass 30' represents the object that would exist if the compression orifice 30 were filled with homogeneous material (this illustrates the shape of the compression orifice 30). Each compression mass 30' belongs to a corresponding compression orifice 30. Each compression centroid 16 is the geometric center of the compression mass 30' of the corresponding compression orifice 30. It should be understood that the compression mass is not part of the invention and is merely described for the purpose of defining the centroid of the orifice.

[0139] Mounting holes 29 are three-dimensional boundaries. Mounting masses 29' represent objects that would exist if mounting holes 29 were filled with homogeneous material (which shows the shape of the mounting holes 29). Each mounting mass 29' belongs to a corresponding mounting hole 29. Each mounting centroid 14 is the geometric center of the mounting mass 29' of the corresponding mounting hole 29.

[0140] It should be understood that the compression portion 18 of any one of the plurality of mounting brackets 19 is not necessarily removably fixed to one of the plurality of compression members 15. Other embodiments may only have a first level 91, which includes removably fixed to a first level shelf 13.1 at each of the plurality of mounting centroids 14, and a plurality of mounting brackets 19 removably fixed to a plurality of apex legs 50 at each of the plurality of mounting brackets 19; however, instead of being removably fixed to one of the plurality of compression members 15, each of the plurality of mounting brackets 19 may be removably fixed to one of the plurality of end caps 28, or not fixed at all.

[0141] It should also be understood that each mounting bracket 19 has a mounting centroid 14 and a compression centroid 16. In the current embodiment, each mounting bracket 19 has a mounting centroid 14 and a compression centroid 16. When referring to an interior angle of the first polygon 11 and comparing it with a corresponding angle in the second polygon 12, the comparison should be made between the angle at the vertex formed by the mounting centroid 14 and the angle at the vertex formed by the compression centroid 16 belonging to the same mounting bracket 19. When referring to an interior angle of the second polygon 12 and comparing it with a corresponding angle in the first polygon 11, the comparison should be made between the angle at the vertex formed by the compression centroid 16 and the angle at the vertex formed by the mounting centroid 14 belonging to the same mounting bracket 19. Furthermore, there is exactly one rotational mounting axis 61 and one rotational compression axis 62 spanning one mounting bracket 19 and another mounting bracket 19; when referring to the rotational mounting axis 61 and its corresponding rotational compression axis 62, the rotational mounting axis 61 and the compression axis 62 should be referenced, and vice versa.

[0142] Therefore, it can be seen that the object of the present invention has been effectively achieved, although modifications and variations to the present invention should be clearly understood by those skilled in the art, and these modifications are intended to fall within the spirit and scope of the claimed invention. It should also be understood that the foregoing description is illustrative of the invention and should not be considered a limitation thereof, wherein various substitutions, modifications, variations, or improvements that are not currently foreseen or anticipated by those skilled in the art can subsequently be made thereto, which are also covered in the following claims. Therefore, other embodiments of the invention are possible without departing from the spirit and scope of the invention.
