     DETAILED DESCRIPTION 
     It is to be understood that the awning assembly is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The multiple embodiments are capable of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted,” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings. 
     Referring now in detail to the drawings, wherein like numerals indicate like elements throughout several views, there are shown in  FIGS. 1-10  various embodiments of an awning assembly. The instant awning assembly allows for connection of a drive assembly and an awning end cap or an awning roller tube in a locked and non-removable fashion such that any removal would require at least some destruction of the spring and/or other components which retain or are retained together. By utilizing this manufacturing technique however, the installers may more easily assemble the awning assembly and install such at whatever location is pertinent and in an easier manner, with fewer parts and with less likelihood of damage to the awning during the installation process. In some non-limiting embodiments, a head, for example a spring, is utilized to engage a drive shaft of the drive assembly relative to an end cap. In other embodiments, however, the drive assembly may be connected to the end cap and the end cap may be snap locked or otherwise engaged by a spring structure to the awning roller tube such that it may not be removed once connected. 
     Referring now to  FIG. 1 , a perspective view of a recreational vehicle (RV)  10  is depicted. The illustrative RV  10  includes a drive and a transmission, not shown, as well as at least one sidewall  12  and a roof  14 . It should be understood that although an RV  10  is referred to in the exemplary embodiments, one skilled in the art should understand that the use of the embodiments described herein is not limited to these drivable vehicles. The term “RV” is also meant to include towable structures, sometimes called campers, commercial vehicles, agricultural vehicles, horse trailers, boats or other marine applications, temporary structures used at sports events (i.e. tailgating), as well as stationary structures such as homes, commercial buildings, flea markets, or other stationary structures. Further, the embodiments may also be used with fixed structures having such shade canopies and therefore, the term RV is not limited to mobile structures but may also include fixed structures. All of these structures are considered to be usable with the awning assembly attachment of the present embodiments. 
     An awning assembly  20  is connected to the sidewall  12  and/or the roof  14  of the vehicle  10 . In other embodiments, the awning assembly  20  may be retractable within the sidewall  12  so as to reduce the airflow interference of the awning assembly  20  while the vehicle  10  is being operated. The awning assembly  20  may be defined by various structures such as roller type awning, cassette awning or other types. For example, the awning assembly  20  may include a roller tube  27  which rotates but does not translate or in some embodiments, a roller tube which rotates and translates. 
     The awning assembly  20  includes an awning or canopy  22  and hardware assemblies  24 ,  26  defined by at least one first arm  28  and at least one second arm  23 . The awning hardware assembly  24  is utilized, according to the instant embodiment, to connect the awning assembly  20  to the sidewall  12  of, for non-limiting example, the vehicle  10  or other fixed or mobile structure. The hardware assembly  24  allows for support of the canopy  22  in an extended position (shown) and/or in a retracted position ( FIG. 2 ). The hardware assemblies, also referred to as hardware,  24 ,  26  support the awning roller tube  27 . The roller tube  27  may be embodied by a tube which, in some embodiments, rotates to either extend or retract, or the awning canopy  22  rotates and translates, or a non-rotating bar of circular or non-circular cross-section. In the non-rotating embodiment, the roller tube  27  may be fixed in position at the sidewall and solely rotates to extend and retract the canopy  22 , and accordingly, the non-rotating bar is located near the leading edge of the canopy  22  which extends and retracts as discussed in further embodiments. In the instant non-limiting embodiment, the awning roller tube  27  rotates and translates with the extension or retraction process. Optionally, the hardware assembly  24  may also provide a pathway for wiring from a power source to the roller tube  27  to drive a motor or alternatively, for example may be routed through a hem in the canopy  22 . Other wiring pathways may also be used however. 
     The canopy  22  includes an inner edge closer to the sidewall of an RV  10  or fixed structure sidewall. The canopy  22  also includes an outer edge or leading edge further from the RV or fixed structure sidewall. In the instant embodiment, the inner edge may be connected to an awning rail and the outer edge may be connected to the roller tube  27 , for example in an awning channel or groove. Extending between the inner and outer edges are first and second lateral edges. 
     The roller tube  27  may be circular in cross-sectional shape in some embodiments. 
     The roller tube  27 , may include a first end and a second end with end caps  31 ,  33  respectively. The roller tube  27  may be rotatably supported at or near ends to allow rotation for extension and retraction of the awning canopy  22 . However, as will be described further, the present embodiments need not be limited to roller tube embodiments, as other types of awnings may be utilized, for example cartridge awnings. 
     Referring still to  FIG. 1 , the awning assembly  20  includes the awning canopy  22  and the first and second hardware assemblies  24  and  26 . The instant hardware assemblies are defined by 4-bar linkages, but various other structure types may be utilized and this embodiment is merely illustrative. In this embodiment, each of the hardware assemblies  24 ,  26  are generally formed in the same way and therefore only hardware assembly  24  will be described. However, these hardware assemblies  24 ,  26  may be different and may also be embodied in differing forms from that which is depicted. The hardware assemblies  24 ,  26  support the canopy  22  in the extended position (shown) and collapses to a compact, nested arrangement when the awning assembly  20  is retracted for road travel or when weather conditions preclude extension of the awning assembly  20 . In the extended position depicted, portions of the hardware assemblies  24 ,  26  extend outwardly from the RV sidewall  12 . As shown in  FIG. 2 , in the retracted position, the hardware assemblies  24 ,  26  are generally positioned in a vertical arrangement near lateral edges of the canopy  22  and along sidewall  12  of the RV  10 . 
     The awning assembly  20  includes at least one hardware assembly  24 , which may include a plurality of arms  28 ,  21 ,  23 ,  15  defining a four bar linkage comprising a first base arm  28 , a second top arm  21 , a third extending arm  23  and a fourth adjustable arm  15 , which may allow for pitch adjustment. Each hardware assembly  24 ,  26  may comprise one or more supports including the first arm  28 , which is mounted to the sidewall  12  ( FIG. 1 ). The second arm  21  is pivotally connected to and extends from the first arm  28 . In the exemplary embodiment, the second arm  21  may extend from the upper end, however this is not limiting and merely one example of a configuration which may be utilized. The second arm  21  may be further sized so as to be in a nested arrangement with either or both of the first arm  28  and a third arm  23 , which may be pivotally connected to an opposite end of the second arm  21  and spaced from the first arm  28 . One or more struts  17  may be utilized to control movement of the second and third arms  21 ,  23 . Additionally, the adjustable arm  15  may be utilized to position and adjust the extended configuration of the awning hardware assemblies  24 ,  26 . 
     Referring now to  FIG. 2 , a front view of the awning assembly  20  is depicted. The canopy  22  is removed and portions of the hardware assemblies  24 ,  26  are not shown. The awning assembly  20  comprises the awning roller tube  27 , as well as first and second end caps  31 ,  33  at ends of the roller tube  27 . Adjacent to the end caps  31 ,  33  are covers  30 ,  32  which hide a connection point between the awning roller tube  27  and the hardware assemblies  24 ,  26 . At ends of the roller tube  27 , the hardware assemblies  24 ,  26  rotatably support the roller tube  27 . The covers  30 ,  32  inhibit a user from pinching a finger or arm in the moving parts of the awning where the awning roller tube  27  connects to the hardware assemblies  24 ,  26 . The covers  30 ,  32  provide an improved appearance as well. Additionally, the covers  30 ,  32  inhibit some contaminants from damaging the pivoting joints which rotatably support the awning roller tube  27  and end caps  31 ,  33 . Each of the covers  30 ,  32  may be a one-piece or multi-piece design. The covers  30 ,  32  engage the hardware assemblies  24 ,  26  and allow for engagement of the end caps  31 ,  33  on the awning roller tube  27 , or both. Mounts  29  are shown as well for connecting the awning assembly  20  to a surface such as sidewall  12  ( FIG. 1 ). The hardware assemblies  24 ,  26  pivot outwardly from the RV and during the unfurling or extension movement of the awning assembly  20 . As this occurs, the canopy or awning material  22  ( FIG. 1 ) extends from the RV sidewall  12  with the awning roller tube  27  to create a covered, shaded area beneath. 
     Referring now to  FIG. 3 , a detailed perspective view of a portion of the awning assembly  20  at one of the joints of the awning assembly  20  is depicted. In this view, the roller tube  27  and the end cap  33  are shown near the cover  32 , which is partially removed from the hardware assembly  26 . In this portion of the awning assembly  20  is a drive assembly  50 . In some embodiments, the drive assembly  50  may be defined by a motor  42  or may be defined by a motor  42  and drive or transmission  56 . Within the hardware assembly  26  is a motor  42 . In the illustrative embodiment, the motor  42  is connected to a drive or transmission  56  together which define the drive assembly  50 . The drive assembly  50  may also comprise at least one drive shaft  60  which extends from the drive  56  and toward the end cap  33  or the awning roller tube  27 , or both. In some embodiments, the motor  42  may be used without a drive  56  and accordingly, in such embodiment, the drive shaft  60  may extend directly from the motor  42 . In some embodiments, a motor  42  and drive assembly  50  are used, the motor  42  may be aligned with the drive  56  rather than at an angle, such as shown at the 90 degree orientation depicted in  FIG. 3 . Further, other angles may be utilized and the right angle motor  42  ( FIG. 3 ) and drive assembly  50  ( FIG. 3 ) arrangement may be altered and still be within the scope of present embodiments. 
     As shown in the hardware assembly  26 , adjacent to the motor  42 , a connector  25  is depicted. The connector  25  is shown and represents one illustrative manner in which electrical wiring may be provided through the hardware  26  and to the motor  42  for powering thereof. Other conduits for running wiring may be utilized. 
     Referring now to  FIG. 4 , an exploded perspective view of a portion of the awning assembly  20  is depicted. In this view, the cover  32  and hardware assembly  26  are exploded to reveal interior components including the drive assembly  50  including, in some embodiments, the motor  42  and drive  56 . The drive  56  may be an angled drive meaning the input of the drive is at one angle and the output is at a second angle, as shown. In other embodiments, the input and output may be aligned or may also be parallel in some embodiments. In some embodiments, the motor and drive may be angled relative to one another or may be aligned. Further, the motor  42  is shown through the hardware  26  but when assembled, may be inserted within the hardware assembly  26 , fully or partially. 
     Various characteristics may be considered in the selection of the motor  42 . Some non-limiting characteristics which may be used to size the motor  42 , desired torque at a roller tube  27 , rotational speed of the roller tube  27 , and gear motor  42  size or limitations if mounted within the hardware or other structures. The motor  42  may be a 12 volt DC motor which may have, for example, a 400 in-lbs stall torque and 300 in-lbs operational torque and may drive an RPM of 25 RPM at an output drive shaft  60 . However, this is merely one embodiment and others may be utilized depending on size and weight characteristics of the awning assembly  20 , as well as other design characteristics which may vary. For example a 24V motor may be used. The motor  42  has a drive shaft  43  which may be connected to or integrally formed with a worm gear or other gear structure which operably engages the transmission  56 . 
     The drive assembly  50  comprises the motor  42  and a transmission or drive  56 . The drive  56  may be an angled drive and in the illustrative embodiment may be a right angle drive. The right angle drive may be provided in some non-limiting embodiments by a worm  80 , a worm gear  82  and a gear box  84  having a plurality of gears  85  therein. In the instant embodiment, the drive  56  may include a lower input which is vertically oriented in the instant embodiment, and an output which is horizontal in the instant embodiment and coaxial with the roller tube  27 . 
     According to the instant embodiment, the motor  42  drives a worm  80  which extends from the motor  42  and is in a worm housing  81 . The worm  80  may be formed on a motor shaft  43  or connected to the motor shaft  43 . Thus the worm  80  may be the drive input shaft  58  ( FIG. 5 ) or the worm  80  may be connected to a drive input shaft  58 . The worm  80  drives a worm gear  82  which in turn drives gears  85  in the gear box  84 . The worm  80  may be formed on a motor shaft or may be connected by, for example, placing a worm  80  over the motor shaft  43 , and may be fixed to the motor shaft for rotation with the motor  42 . As the worm  80  and the worm gear  82  rotates, a plurality of gears  85  on the interior of the gear box  84  causing rotation of an output drive shaft  60 . The output drive shaft  60  rotates causing rotation of roller tube  27  by connection and/or engagement of the end cap  33 . 
     The above design characteristics, for example, speed or torque may also be measured at the drive shaft  60  rather than the roller tube  27 . In the illustrated embodiment, the shaft  60  extends from the gear box  84  into the end cap  33  and/or awning roller tube  27 . In some embodiments however, the shaft  60  may extend from the roller tube  27  into the gear box  84 . The gear architecture, gear sizes and ratios may be sized and adjusted depending on the desired speed and torque at the shaft  60  or the roller tube  27 . Additionally, the transmission  56  may include one or more joints to compensate for off-axis operation of the roller tube  27  wherein the roller tube  27  is not aligned with the drive shaft  60  of the drive  56 . 
     The motor  42  and the drive  56  may be manufactured as a single structure or may be joined together as shown by fasteners  41 . Either embodiment is considered within the scope of the present claims. Further the drive assembly  50  may comprise an angled transmission which receives an input in one direction and provides an output in a second direction which is non-coaxial and/or non-parallel to the first direction. In this embodiment, the worm  80  receives input in a direction, at least in part, determined by the motor  42  and the gear box  84  provides an output at drive shaft  60  in a second direction, which according to some embodiments, is generally a right angle, although such angle should not be considered limiting. Still further, the motor  42  and drive  56  may be aligned rather than the angled configuration shown, depending on the arrangement of the awning assembly  20 . 
     Exploded from the drive shaft  60  may be a head which according to some embodiments may be a spring  70 . The head passes through the end cap  33  and/or the awning roller tube  27  and once past a threshold, will retain the drive assembly  50  and hardware  26  to the end cap  33  and/or awning roller tube  27 . The head may be formed in various manners including formed integrally on the shaft  60  or connected thereto. The head may be formed in various manners and according to the illustrative, non-limiting embodiment, the head is defined by a spring  70  which has wings  72 ,  74  that expand once the spring  70  moves beyond the threshold, which may be defined by either or both of the end cap  33  and awning roller tube  27 . Once the spring  70  is expanded, the shaft  60  cannot be removed from the end cap  33  or awning roller tube  27  and the structures is assembled and retained together. A clip  78  is also shown which retains the spring  70  or head on the drive shaft  60 . 
     Referring now to  FIG. 5 , a rear section view of a portion of the awning assembly  20  is depicted, sections along line  5 - 5  of  FIG. 3 . The section view is cut to depict the motor  42  and input shaft  58  to the drive  56 . The drive assembly  50  comprises the drive  56 , which includes an input shaft  58  to provide rotation to the drive  56 . The rotation is input from the motor  42  and the input shaft  58  may be the motor shaft  43 , engaging the drive  56 , or the input shaft  58  a distinct structure which may be coupled to the motor shaft  43 . For example, in some embodiments, the input shaft  58  may be a worm which engages a worm gear. The input shaft  58  may rotate one or more gears of the drive  56  in order to cause rotation of an output drive shaft  60 . The drive shaft  60  speed and torque may be varied by varying the gear sizes and the input speed and/or torque of the motor  42 . Accordingly, such speed and torque output at the drive shaft  60  may be dependent upon the length of the awning assembly  20  ( FIG. 1 ) and the requirements necessary to rotate such canopy  22  ( FIG. 1 ) and awning roller tube  27  ( FIG. 1 ). 
     As indicated previously, the drive shaft  60  may also extend from a motor  42  or may extend from a drive, such as the drive  56 , or an alternate drive type. For example, various drive types may be utilized in the drive  56 . The instant embodiment may utilize a worm and a worm gear to drive the gears, while various alternate types of drives, geared or otherwise, may be utilized if a drive  56  is positioned between the motor  42  and the awning roller tube  27 . According to the instant embodiment, the motor  42  may cause rotation of drive  56  and the awing roller tube  27 . 
     Referring now to  FIG. 6 , a partially exploded perspective view of a portion of the awning assembly  20  is depicted. In this view, the awning roller tube  27  is exploded away from the drive  56  and the end cap  33  ( FIG. 4 ) is removed to depict the drive shaft  60  extending at or near the end of the awning roller tube  27 . In the instant illustrative embodiment, the drive shaft  60  includes a shoulder  64  against which the spring  70  is located. Again, other forms of a head may be utilized but the use of a spring structure provides for expansion of the head once it is past a threshold within either or both of the end cap  33  or awning roller tube  27 . The drive shaft  60  is generally cylindrical but various shapes may be utilized and may further comprise a key surface  66  which allows the shaft  60  to engage the end cap  33 . With the engagement of the key surface  66  through a keyway  38  ( FIG. 4 ) in the end cap  33 , the rotation of the drive shaft  60  causes rotation of the awning roller tube  27 . 
     With additional brief reference to  FIG. 4 , the end cap  33  is shown with a detail view. The keyway  38  is shown with a shape corresponding to the shaft  60  and specifically the key surface  66 . The keyway surface  67  is engaged by the key surface  66 . Various structures for engagement may be alternatively used. 
     Additionally, during insertion of the drive shaft  60  into the end cap  33  and/or roller awning tube  27 , the spring  70  is compressed so that the spring can pass through the end cap  33 . Once the spring  70  passes through the end cap  33 , the spring expands and locks the drive shaft  60  to the end cap  33  and/or awning roller tube  27 . This eliminates the need for further fasteners such as nuts and bolts, rivets or lock washers, all of which are desired to reduce or eliminate by installers. Alternatively, rather than compress the spring  70 , the area of the end cap  33  or awning roller tube  27  which is engaged by the spring  70  may expand slightly to allow the passage of the spring or head there through. 
     Referring now to  FIG. 7 , an exploded perspective view of the end cap  33  and drive shaft  60  is depicted. The drive assembly  50  is shown having the drive shaft  60 . One skilled in the art will recognize this may be a shaft from a motor or a drive, as depicted. The drive shaft  60  extends from the drive assembly  50  and includes the shoulder  64  and the key surface  66 . The end cap  33  is shown spaced from the drive shaft  60 . The end cap  33  includes a hub  34  and a peripheral circumferential surface  35 . Extending between the hub  34  and the peripheral circumferential surface  35  are strengthening ribs  36 . The end cap  33  may also include fastener holes  37  for screws or rivets which connect the end cap  33  to the awning roller tube  27  ( FIG. 6 ). The interior of the hub  34  includes a keyway  38  which has flat surfaces which correspond to the key surfaces  66  of the drive shaft  60 . The drive shaft  60  extends at least partially through the hub  34  so that the key surface  66  engages the keyway  38  allowing torque transfer. 
     Shown between the drive shaft  60  and the end cap  33  is the spring  70 . The spring  70  includes at least one wing  72  and, according to the instant embodiment, includes first and second wings  72 ,  74 . The spring  70  includes a central aperture  76  which allows the spring  70  to pass on to an end of the drive shaft  60 . The aperture  76  is smaller than the diameter of the shoulder  64  so that the spring  70  engages the shoulder  64  and is located. The drive shaft  60  also includes a groove  62  so that when the spring  70  is located against the shoulder  64 , the groove  62  is exposed slightly and a clip  78  may lock the spring  70  onto the drive shaft  60 . Other arrangements and/or configurations may be used to lock the drive shaft  60  to at least one of the end cap  33  and the awning roller tube  27 . 
     To insert the drive shaft  60  into the end cap  33 , the wings  72 ,  74  need only be compressed to allow passage through the keyway  38 . The keyway  38  is generally located within the hub  34  and has a peripheral edge which is spaced from the hub  34  creating a distance between a wall of the hub  34  and the keyway  38 . Within this distance, the spring  70  may expand to lock the drive shaft  60  in position relative to the end cap  33 . Once the spring  70  clears the keyway  38 , the wings  72 ,  74  can expand within the hub  34  and thereby lock the drive shaft  60  to the end cap  33  and/or the awning roller tube  27 . In order to allow the spring  70  to expand, the key surface  66  must be inserted into the keyway  38 . Alternatively stated, if the key surface  66  and the keyway  38  are not properly aligned, the spring  70  will not fully pass through the end cap  33  and expand within the hub  34 . 
     With additional reference again to the detail cloud of  FIG. 4 , the keyway  38  may provide an edge  39  against which the head or spring  70  catches to inhibit rotation of the spring relative to the keyway  38 . 
     Referring now to  FIG. 8 , a rear section perspective assembly view of the relevant portion of the awning assembly  20  is depicted. In this view, the spring  70  is inserted into the end cap  33 . The drive shaft  60  extends from the drive  56  and into the end cap  33 , which is connected to the awning roller tube  27 . The hub  34  receives the drive shaft  60  and the spring  70  is shown extending into the end cap  33  and expanded from the keyway  38  ( FIG. 4 ) radially, outwardly toward a wall  35  defining the hub  34 . In this way, once the drive shaft  60  is pushed into the end cap  33  and/or the roller awning tube  27 , the structure is locked in place by wings  72 ,  74 . In other embodiments, a hub  34  may be formed within the roller tube  27  and the spring  70  may be inserted to lock in such roller tube  27  but rather than the end cap  33 . In either embodiment, no further fasteners are required to retain the drive shaft  60  in position relative to the end cap  33  and/or the awning roller tube  27 . As a result, the structure cannot be disassembled, however, the installation is significantly eased and the number of parts required for the assembly is reduced, which reduces the complexity and the likelihood of incorrect assembly and/or installation. 
     Referring to  FIG. 9 , a further alternate embodiment is shown in a section view. The embodiment provides the hardware assembly  26 , the drive assembly  50  and the awning roller tube  27 . The embodiment provides that the connection of the head, embodied by the spring  70 , is disposed in a hub  134  within the awning roller tube  27 . As in the previous embodiment, the hub  134  may be defined in part by a wall  135  and have a plurality of strengthening ribs  136 . This embodiment is made possible additionally by lengthening the drive shaft  160  extending from the drive assembly  50 . The spring  70  is merely one embodiment of a head and other embodiments may be utilized. Further, rather than expand and compress the head, the roller tube  27  may comprise the expanding and compressing structures. For example, one or more springs may be located within the hub  134  to compress and allow a head on the drive shaft  60 ,  160  to pass, then expand once the head passes a threshold position, locking the shaft  60 ,  160  in position. 
     Still further, and with reference to  FIG. 10 , an additional alternative embodiment is provided in perspective view. In the previous embodiments, the spring has been attached to the drive shaft  60  of the drive assembly  50 . However, according to alternate embodiments, an end cap  133  is provided wherein a spring  170  is provided. In some embodiments, the spring may be a wire type spring which flexes to allow the accept the drive shaft  60 . At some location, the spring  170  may be seated in a groove  62 . While the spring  170  is shown in a wire form, the spring may alternatively be a flat spring having at least one edge which is seated in the groove  62 . 
     Still further, in some embodiments, the spring  170 , wire or flat spring for non-limiting example, may be located within the awning roller tube. As with earlier embodiments, the drive shaft  60  may be lengthened to reach such location within an exemplary awning roller tube  27 . 
     While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the invent of embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teaching(s) is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure. 
     All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. 
     Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. 
     As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law. 
     As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc. 
     It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited. 
     In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03. 
     The foregoing description of several methods and an embodiment of the invention has been presented for purposes of illustration. It is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention and all equivalents be defined by the claims appended hereto.
