TECHNICAL FIELD 
       [0001]    The present specification generally relates to fluid receptacles and, more specifically, configurable fluid receptacles with internal bladders. 
       BACKGROUND 
       [0002]    Fluid tanks may be bulky, heavy, and cumbersome to handle, leading to difficulty in transporting and/or shipping the fluid tank. Additionally, fluid tanks may have fixed volumes, which may cause users to replace fluid tanks depending on changing needs. Finally, fluid tanks may not be aesthetically pleasing, increasing the difficulty of incorporating fluid tanks positioned within outdoor landscapes or on rooftop surfaces, for example. 
         [0003]    Accordingly, alternative fluid receptacles may be desired.

     DETAILED DESCRIPTION 
       [0020]    Referring generally to  FIG. 1 , embodiments described herein are directed to configurable fluid receptacles with internal bladders. The configurable fluid receptacles described herein are comprised of detachable structural panels of various geometries that can be configured to form structures of different shapes and sizes. The detachable structural panels may be rectangular for example and may be configured to form fluid receptacles that also include, for example, a raised garden, a shelving unit, or a lawn chair. The detachable structural panels may further be curvilinear and configured to form, for example, a structure representing a wine barrel. The configurable fluid receptacles further comprise an expandable internal bladder with an inlet that may pass through at least one of the detachable structural panels. The expandable internal bladder receives and retains fluid delivered to the expandable internal bladder from an exterior source, for example a rain gutter downspout. The expandable internal bladder is fluidly coupled to an outlet, which may comprise a spout, that may pass through one of the detachable structural panels. The outlet is operable to remove fluid from the expandable internal bladder. The expandable internal bladder may additionally include air relief valves for efficient fluid flow into and out of the expandable internal bladder, as well as attachment means for attaching the expandable internal bladder to interior surfaces of the structure formed by the detachable structural panels. Strengthening members, such as metal or plastic rods, may be inserted through interlocking members of the detachable structural panels for additional structural integrity. Various embodiments of configurable fluid receptacles with internal bladders will be described in more detail herein. 
         [0021]    Referring now to  FIG. 1 , one embodiment of a configurable fluid receptacle  100  is depicted. The configurable fluid receptacle  100  includes a plurality of detachable structural panels  10  that are connected to one another via interlocking members  20  to form the configurable fluid receptacle  100 . The plurality of detachable structural panels  10  includes orientation panels  12 , side panels  14 , bottom panels  16 , and top panels  18 . In some embodiments, the configurable fluid receptacle  100  may include strengthening members  21  inserted through interlocking members  20  between adjacent detachable structural panels  10 , as discussed herein. The configurable fluid receptacle  100  further includes an expandable internal bladder  30  with an inlet  32  and an outlet  34 . The configurable fluid receptacle  100  may include a valve  36 , such as a check valve, fluidly coupled to the inlet  32  of the expandable internal bladder  30 . The valve  36  may allow unidirectional fluid flow into or out of the expandable internal bladder  30 . The valve  36  may also be fluidly coupled to a fluid delivery source  110 , depicted in  FIG. 1  as an expandable hose attached to a gutter downspout. The fluid delivery source  110  may deliver fluid, such as a liquid or a gas, to the configurable fluid receptacle  100 . In the illustrated embodiment, the fluid delivery source  110  may deliver rain water collected in an attached gutter to the configurable fluid receptacle  100  as the rain water travels through the fluid delivery source  110  due to gravity. Other embodiments may use mechanical pumps or other methods of forced fluid delivery to deliver fluid to the configurable fluid receptacle  100 . The valve  36  may be mounted on the configurable fluid receptacle  100  or may pass through one of the plurality of detachable structural panels  10 , as shown in  FIG. 1 . The expandable internal bladder  30  may further include attachment portions to attach to internal surfaces of the plurality of detachable structural panels  10 , as well as vents or air relief valves to allow for efficient fluid flow, as discussed herein. 
         [0022]    Because the configurable fluid receptacle  100  is comprised of the plurality of detachable structural panels  10 , the configurable fluid receptacle  100  may be configured into different structures, depending on the geometry of each one of the plurality of detachable structural panels  10 . For example, in  FIG. 1 , the configurable fluid receptacle  100  is configured to include a raised or elevated garden space  40 . The garden space  40  may be created by a top surface  50  of the configurable fluid receptacle  100  that is recessed from top edges  52  of the side panels  14 , where the side panels  14  form the perimeter of the top surface  50  of the configurable fluid receptacle  100 . In the illustrated embodiment, soil may be placed in to a recessed area  54  created by the top surface  50  surrounded by walls formed by side panels  14 , as shown. In other embodiments, the recessed area  54  may not be filled with soil to form the garden space  40 , and instead may function as storage, such as shelving. A lid (not shown) may also be attached to the top edges  52  to form a drawer for storage space. In other embodiments, the configurable fluid receptacle  100  may be configured to form structures such as lawn chairs, shelves, and other structures as discussed herein. 
         [0023]    Referring now to  FIG. 2 , some of the plurality of detachable structural panels  10  that form the configurable fluid receptacle  100  are depicted detached from each other. Because the configurable fluid receptacle  100  is formed from detachable structural panels  10 , the configurable fluid receptacle  100  may be assembled and disassembled, allowing for efficient transportation and/or shipping of the configurable fluid receptacle  100 . Further, the shape and size of the configurable fluid receptacle  100  may be adjusted by including additional or fewer detachable structural panels  10  as desired. For example, if a user desires a configurable fluid receptacle  100  with increased storage capacity, the user may adjust the configuration of the configurable fluid receptacle  100  to include additional detachable structural panels  10 . Likewise, if the user wishes to reduce the capacity or footprint of the configurable fluid receptacle  100 , the user may remove detachable structural panels  10  from the configurable fluid receptacle  100 . 
         [0024]    In the illustrated embodiment, all of the detachable structural panels  10  have substantially similar thicknesses  11 . The thicknesses  11  may be consistent across each detachable structural panel  10 , allowing for the detachable structural panels  10  to be stacked upon each other. Stacking the detachable structural panels  10 , regardless of the geometry of each individual detachable structural panel  10 , may allow for reduced airspace required during shipping, which may result in reduced costs associated with shipping, storage, and/or transportation. The configurable fluid receptacle  100  may also be disassembled and stored by stacking the detachable structural panels  10 , requiring a reduced amount of space to store the configurable fluid receptacle  100 . In other embodiments, some of the detachable structural panels  10  may not have substantially the same thickness  11  or consistent thicknesses across the detachable structural panel  10 , and in yet other embodiments of the configurable fluid receptacle  100 , the detachable structural panels  10  may be different shapes and sizes. However, because the detachable structural panels  10  are detachable from each other, the configurable fluid receptacle  100  may be disassembled as desired and transported, shipped, or stored while requiring reduced airspace when compared to the assembled configurable fluid receptacle  100 . 
         [0025]    The detachable structural panels  10  further include attachment portions  60  that may extend through the thickness  11  of the detachable structural panels  10 . Each detachable structural panel  10  may include several attachment portions  60  that allow users to attach the expandable internal bladder  30  to the detachable structural panel  10 . The attachment portions  60  may have removable caps (not shown) that may allow any of the attachment portions  60  to become inlets or outlets for the expandable internal bladder  30 . In instances where an individual attachment portion  60  is not being used as an inlet or an outlet for the expandable internal bladder  30 , the attachment portion  60  may serve as an attachment point for the expandable internal bladder  30  to attach to an inner surface  19  of the detachable structural panel  10 , which may provide structural support for the expandable internal bladder  30 . The attachment portion  60  may allow the expandable internal bladder  30  to attach by, for example, a rotational locking mechanism, a snap fit mechanism, a ball and socket mechanism, or another mechanical attachment system. 
         [0026]    Each of the orientation panels  12 , side panels  14 , and bottom panels  16 , and top panels  18  are configured to interlock with each other with interlocking members  20 , allowing for customization by a user in creating configurable fluid receptacles  100  of a desired size. Accordingly, the configurable fluid receptacle  100  may be configured to form different shaped structures and different sizes. Adding or removing detachable structural panels  10  from the configurable fluid receptacle  100  may adjust the size of the configurable fluid receptacle  100 , while configuring the detachable structural panels  10  at various angles may form configurable fluid receptacles  100  of different structures, as discussed herein. For example, a user can configure the configurable fluid receptacle  100  to have a rectangular shape, a hexagonal shape, a diamond shape, and the like using rectangular detachable structural panels  10 . In other embodiments, the configurable fluid receptacle  100  can be configured to form other shapes depending on the geometry of the detachable structural panels  10 . Furthermore, some detachable structural panels  10  may be adjustable in size and geometry by including scorelines that allow users to snap sections of the detachable structural panel  10  off and change the size or geometry of the detachable structural panel  10 , as discussed below. 
         [0027]    Referring now to  FIGS. 3 and 4 , the expandable internal bladder  30  is shown in isolation in  FIG. 3  and the expandable internal bladder  30  is positioned within the interior cavity  102  of the configurable fluid receptacle  100  in  FIG. 4 . In  FIG. 4 , the configurable fluid receptacle  100  is shown partially constructed, without side panels  14  and with bottom panels  16  in a raised position, partially forming the lower half of the configurable fluid receptacle  100  of  FIG. 1 . The expandable internal bladder  30  may include inlets  32 , attachment devices  33 , outlets  34 , and air relief valves  35 . The expandable internal bladder  30  may be formed from any material capable of fluid retention, such as plastic, canvas, leather, neoprene, and the like. The expandable internal bladder  30  may further be semi-rigid or flexible. In the illustrated embodiment, the expandable internal bladder  30  is comprised of plastic and is flexible, allowing the expandable internal bladder  30  to collapse upon itself or roll up for storage and/or transportation. The expandable internal bladder  30  includes multiple inlets  32  and outlets  34 , allowing users to orient the expandable internal bladder  30  as desired and using as many or as few inlets  32  as necessary to deliver fluid to or remove fluid from the expandable internal bladder  30 . The expandable internal bladder  30  may further include additional inlets and valves located at various positions on the expandable internal bladder  30 , allowing flexibility in positioning the expandable internal bladder  30  in the interior cavity  102  in different configurations and also allowing the expandable internal bladder  30  to be reused when reconfiguring the configurable fluid receptacle  100 . The inlets  32  and outlets  34  may be placed along any surface and at any height of the expandable internal bladder  30  and may include removable plugs (not shown) to prevent fluid flow into or out of the inlet when not in use. Each inlet  32  may further include a check valve, or a removable check valve may be included to position with the inlet being used. Similarly, the expandable internal bladder  30  may include additional outlets  34  positioned at various locations on the expandable internal bladder  30 , allowing for fluid to be removed from the expandable internal bladder  30  from different outlets. In some embodiments, more than one inlet  32  may be used to deliver fluid to the expandable internal bladder  30 , similarly, more than one outlet  34  may be used to remove fluid from the expandable internal bladder  30 . 
         [0028]    The attachment devices  33  may be integrated into the expandable internal bladder  30  or may be attached to the expandable internal bladder  30 . The attachment devices  33  allow the expandable internal bladder  30  to be attached to the internal walls of the configurable fluid receptacle  100 , providing the expandable internal bladder  30  with structure and allowing increased utilization of the internal volume of the expandable internal bladder  30  available for receiving fluid. The attachment devices  33  of the expandable internal bladder  30  attach to corresponding attachment openings on internal surfaces of the detachable structural panels  10 , as discussed below. The attachment devices  33  may be complementary to the attachment portions  60  of the detachable structural panels  10 , and may include features such as fins  38  (shown at mating faces of inlets  32 ) that allow the attachment devices  33  to attach to the attachment portions  60  of the detachable structural panels  10 . 
         [0029]    The expandable internal bladder  30  also includes the air relief valves  35 . Air relief valves  35  may allow for airflow that may assist in removing fluid from the expandable internal bladder  30  through the outlet  34 . As fluid flows from the expandable internal bladder  30  through the outlet  34 , air passing through air relief valves  35  may allow fluid to flow more quickly at an increased flowrate by reducing internal pressure of the expandable internal bladder  30 . Because the expandable internal bladder  30  may have a fixed volume, multiple expandable internal bladders  30  may be fluidly coupled and placed into the interior cavity  102  of the configurable fluid receptacle  100 . For example, two expandable internal bladders may be fluidly coupled such that the outlet of the first expandable internal bladder is connected to the inlet of the second expandable internal bladder, thereby increasing the fluid retention capacity of the configurable fluid receptacle  100 . 
         [0030]    As fluid flows from the fluid delivery source  110  to the configurable fluid receptacle  100 , the fluid reaches the inlet  32  of the expandable internal bladder  30 . The fluid flows past the valve  36  and into the interior cavity of the expandable internal bladder  30 . The outlet  34  may include the spout  37 . In some embodiments, the spout  37  may be attached to the expandable internal bladder  30 , while in other embodiments, the spout  37  may be attached to the configurable fluid receptacle  100  and the outlet  34  may be fluidly coupled to the spout  37 . The spout  37  may be operable to open and close a valve allowing fluid to flow thorough the outlet. When a user desires to remove fluid from the expandable internal bladder, the user may operate the outlet  34  or spout  37  to open the valve. In some embodiments, the outlet  34  may comprise a flexible hose that may be joined to an external spout, for example, or other fluid delivery extensions that extend through one of the detachable structural panels  10  and allows fluid to be removed from the expandable internal bladder  30 . In some embodiments, the inlet  32  may be positioned higher than the outlet  34 , such that gravity will allow fluid to flow from the outlet. In other embodiments, pumps may be included to force fluid into or out of the expandable internal bladder  30 , as discussed further below. 
         [0031]    Referring now to  FIG. 4 , the configurable fluid receptacle  100  is depicted with side panels  14  and top panels  18  removed. The remaining plurality of detachable structural panels  10 , in this case orientation panels  12  and bottom panels  16  (shown in a raised position), are shown interlocked with each other to form the lower portion of the configurable fluid receptacle  100 . Each of the plurality of detachable structural panels  10  has interlocking members  20  that extend linearly along the perimeter of each of the plurality of detachable structural panels  10 . The interlocking members  20  allow each of the detachable structural panels  10  to be positioned adjacent to each other and to interlock, forming, for example, a coplanar surface or a perpendicular corner, as shown in  FIG. 4 . The detachable structural panels  10  may also be positioned such that the detachable structural panels  10  interlock and form angular structures, such as hexagonal structures and the like. Also, depending on the geometry of the interlocked detachable structural panels  10 , other structures may be formed by positioning detachable structural panels  10  adjacent to each other. As shown in  FIG. 4 , the expandable internal bladder  30  is positioned within the interior cavity  102  of the configurable fluid receptacle  100 . Because the expandable internal bladder  30  may be flexible, the size and volume of the expandable internal bladder  30  may not correspond to the size and volume of the configurable fluid receptacle  100 . Further, strengthening members  21  may be inserted through the interlocking members  20  to increase the structural rigidity of the configurable fluid receptacle  100 . Strengthening members  21  may include plastic, metal, or wood rods/dowels, or other similar materials. In some embodiments (not shown) the configurable fluid receptacle  100  may be constructed substantially as shown in  FIG. 4 , and instead of an additional top layer being added to cover the configurable fluid receptacle  100 , the expandable internal bladder  30  may be cut open and stretched across the configurable fluid receptacle  100  such that an open container is formed to receive, for example, rain water. A filter or a form of netting may be laid across the top to prevent debris from entering into the configurable fluid receptacle  100 . This embodiment may be used in industrial environments or locations where rainfall may occur in high volumes, making direction of rain water through gutter or piping systems difficult. 
         [0032]    Referring now to  FIGS. 5-7 , one detachable structural panel  10 , specifically one orientation panel  12 , is depicted. The orientation panel  12  includes orientation corner  26 , interlocking members  20 , strengthening member openings  24 , and attachment portions  60 . In this embodiment, the interlocking members  20  have a rectangular geometry and extend linearly along the perimeter of the orientation panel  12 . In other embodiments, the interlocking members  20  may have a different geometry, such as elliptical or curved geometries, and the interlocking members  20  may extend at angles along the perimeter of the orientation panel  12 . The interlocking members  20  are spaced from one another to form gaps  22 . In  FIG. 5 , only some of the gaps  22  between the interlocking members  20  are labeled for ease in illustration. Each gap  22  has substantially the same width as a single interlocking member  20 . Accordingly, when the interlocking members  20  of one orientation panel  12  are positioned adjacent to another detachable structural panel  10 , the interlocking members  20  of each detachable structural panel  10  fills a substantial entirety of the corresponding gap  22  on the adjacent detachable structural panel  10 . The interlocking member  20  may fit into the corresponding gap  22  with, for example, a friction fit, a snap fit, an interference fit, or the like. The interlocking members  20  may have strengthening member openings  24 . The strengthening member openings  24  may be of different geometries, as discussed herein. The strengthening member openings  24  may be transverse to an outer surface  17  of the detachable structural panel  10 . Strengthening members  21 , such as plastic or metal rods as discussed above, may be inserted through the strengthening member openings  24  to provide structural rigidity and to prevent the detachable structural panels  10  from separating or becoming detached. 
         [0033]    The orientation panel  12  further includes attachment portions  60 . The attachment portions  60  may be openings that extend through the orientation panel  12  or may be positioned on an inner surface of the orientation panel  12 . The attachment portions  60  may allow the attachment devices  33  of the expandable internal bladder  30  to be attached to the orientation panel  12  at the attachment portions  60 , or may allow for the fluid inlet  32  connection or fluid outlet  34  connection. The orientation panel  12  has outer surface  17  that is textured and/or stylized to resemble wood grain. The outer surface  17  may be configured to resemble different textures and/or patterns, which may provide aesthetic appeal to users. In some embodiments, a graphical image may be applied to the outer surface  17 , such as a sticker or a painting, while in other embodiments panels may be molded to achieve this aesthetic appeal. This may allow users additional flexibility in incorporating the configurable fluid receptacle  100  into existent landscaping, for example, and may allow the configurable fluid receptacle to blend into the natural surroundings. For example, the configurable fluid receptacle  100  may be configured to resemble natural stones or boulders, adding novelty to the configurable fluid receptacle  100 . Other embodiments may have printed features on the outer surface  17  that likewise provide aesthetic appeal. 
         [0034]    Referring now to  FIG. 6 , the orientation corner  26  of the orientation panel  12  is depicted in detail. The orientation corner  26  allows the orientation panel  12  to be properly oriented when configuring the configurable fluid receptacle  100 . The orientation corner  26  is unlike the remaining corners of the orientation panel  12  in that the orientation corner  26  is comprised of two interlocking members  20  that are normal to each other. The orientation corner  26  includes strengthening member openings  24  along the X-axis, Y-axis, and Z-axis as shown in  FIG. 6 , allowing the orientation panel  12  to form corners of the configurable fluid receptacle  100  and also to receive strengthening members (not shown) that extend through the orientation panel  12 . Because the orientation corner  26  includes two interlocking members  20 , the orientation corner  26  may increase the structural rigidity of the configurable fluid receptacle  100 . 
         [0035]    The orientation corner  26  of the orientation panel  12  may be positioned such that a lateral edge  25  forms part of the bottom surface of the configurable fluid receptacle  100 . Accordingly, the orientation corner  26  ensures that the orientation panels  12  may only be oriented in a certain configuration. Additionally, the orientation corner  26  may allow for specific supporting rib structures  70 ,  72  on inner surface  19  of the orientation panel  12  to be used that may be configured to reduce the amount of material used to form the orientation panel  12 . For example, referring to  FIG. 7 , the orientation panel  12  is shown in rear view. Because the orientation corner  26  will be positioned at the bottom of the configurable fluid receptacle  100 , supporting rib structure  72  may extend vertically and horizontally across substantially an entire lower portion  73  of the orientation panel  12 , while supporting rib structure  70  along an upper portion  71  may not extend along the entire upper portion  71  of the orientation panel  12 . The additional supporting rib structure  72  may increase the strength and resist deformation of the orientation panel  12  as additional detachable structural panels  10  are attached to the orientation panel  12 . The reduced amount of supporting rib structure  70  along the upper portion  71  of the orientation panel  12  may decrease production costs and times and decrease complexity of forming molds and apparatuses, which may increase yield and manufacturing performance. In the illustrated embodiment, the orientation panel  12  has one orientation corner  26 , while in other embodiments, the orientation panel  12  may have multiple orientation corners distinguishable from each other. Finally, although the orientation panel  12  is illustrated in  FIGS. 5-7 , the features described herein may apply to any of the detachable structural panels  10 , including side panels  14 , bottom panels  16 , and top panels  18 . 
         [0036]    Referring now to  FIGS. 8 and 9 , an alternative embodiment of a configurable fluid receptacle  200  is depicted. In this embodiment, the configurable fluid receptacle  200  is comprised of curved detachable structural panels  206  with non-planar contours configured to resemble a wine barrel. Each of the curved detachable structural panels  206  has an outer surface  208  that may be constructed to resemble, for example, wood grain or wood grain texture for aesthetic purposes, as shown. This may be achieved using, for example, a graphical image or a molding process. The detachable structural panels  206  may include attachment portions  210  and orientation portions  220 . The attachment portions  210  may allow an internal bladder  230  to be attached to an interior surface  209  of the detachable structural panel  206 . Additionally, when not in use, the attachment portions  210  may have removable caps (not shown) that cover the attachment portions  210 . The orientation portion  220  may allow each detachable structural panel  206  to be oriented properly such that the orientation portion  220  is positioned near a bottom surface  213  of the configurable fluid receptacle  200 . 
         [0037]    The configurable fluid receptacle  200  may further include top panel  202  and bottom panel  204 . In this embodiment, the detachable structural panels  206  are not of uniform geometry and dimension and have non-planar contours. However, the curved detachable structural panels  206  are stackable, which may result in the reduced storage space discussed above, as well as reduced shipping costs. Further, the configurable fluid receptacle  200  includes inlet  232  on the top panel  202  and outlet  234  near the bottom surface  213 , allowing fluid to enter and flow through the internal bladder  230  by gravity. The outlet  234  may be connected to a spout  236  or other valve that allows users to release fluid from the internal bladder  230 . Finally, because the detachable structural panels are uniquely shaped in this embodiment, the interior cavity  240  formed by the configurable fluid receptacle  200  may be of fixed volume. 
         [0038]    Referring now to  FIG. 10 , an alternative embodiment of a configurable fluid receptacle  300  forming a lawn chair is depicted. This embodiment is constructed of detachable panels  314  of various sizes and geometries. The configurable fluid receptacle  300  may include orientation panels  302 , side panels  312 , and adjustable panels  304 ,  306 ,  308 ,  310 . The orientation panels  302  and side panels  312  function as described herein, however, the adjustable panels  304 ,  306 ,  308 ,  310  may include score lines that allow users to bend-and-snap the adjustable panel  316  to form different shapes out of rectangular panels by applying a torque to the adjustable panel  316  along the scoreline. For example, adjustable panel  308  that forms the seat of the lawn chair in this embodiment may have a curved score line along a corner of the adjustable panel  308  that allows the user to change the geometry of the adjustable panel  308  if desired. Because the geometry change is optional, the adjustable panel  308  still ships and otherwise operates as a side panel  312 , resulting in the benefits described herein. 
         [0039]    Referring now to  FIG. 11 , a stacked embodiment of a configurable fluid receptacle  400  is illustrated. In this embodiment, the configurable fluid receptacle  400  includes orientation panels  406 , side panels  404 , top panels  402 , and bottom panels  408 . The configurable fluid receptacle  400  further includes a pump  410  positioned inside the interior cavity  412  formed by the configurable fluid receptacle  400 . In other embodiments, the pump  410  may be positioned external to the configurable fluid receptacle  400 . The configurable fluid receptacle  400  further includes inlet  430  and outlets  450 . The inlet  430  may deliver fluid to an expandable internal bladder  420  positioned in the interior cavity  412 , while fluid may be removed from the expandable internal bladder  420  through outlets  450 . The pump  410  may pump fluid up through elevated outlets, such as elevated outlet  452  in  FIG. 11 . In this embodiment, top surfaces  403  may serve as shelving for storage. 
         [0040]    The above-described disclosure may allow for fluid tanks to be configured to different shapes, sizes, and capacities. The configurable fluid receptacles described herein may be easy to ship and handle due to detachable structural panels that detach from one another and may be stackable. Expandable internal bladders may receive and retain fluid delivered to the configurable internal bladders and fluid may be removed from the expandable internal bladders through outlets, which may be fluidly coupled to spouts. Some embodiments may include pumps to remove fluid from the expandable internal bladder. If desired, additional expandable internal bladders may be fluidly coupled and positioned inside the configurable fluid receptacles described herein in order to increase fluid volume capacity. Finally, the configurable fluid receptacles described herein may be comprised of detachable structural panels that have aesthetically pleasing outer surfaces, such as wood grain texture or printing, allowing the configurable fluid receptacle to mesh with other outdoor landscaping. 
         [0041]    While particular embodiments have been illustrated and described herein, it should be understood that various other changes and modifications may be made without departing from the spirit and scope of the claimed subject matter. Moreover, although various aspects of the claimed subject matter have been described herein, such aspects need not be utilized in combination. It is therefore intended that the appended claims cover all such changes and modifications that are within the scope of the claimed subject matter.
