ADJUSTABLE JOISTS FOR SUSPENDED ACCESS PLATFORMS

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63/671,594, filed Jul. 15, 2024, which is hereby incorporated herein by reference in its entirety and for all purposes.

BACKGROUND

The present disclosure relates generally to the field of construction and temporary structures that are erected to access various parts of various structures. In one aspect, the disclosure relates to work platform systems and adjustability of components thereof to accommodate work platform systems of various sizes.

Work platforms and other access structures, including suspended work platform systems and scaffolding, enable workers to access otherwise difficult to reach worksites and can be assembled on the job site as needed. For example, when working on structures such as bridges where there is no stable or suitable ground surface for building up standard supported work platforms, suspended work platforms enable workers to access the undersides and sides of these structures. Suspended work platforms also eliminate the need to build standard work platforms and platform systems to significant and unwieldy heights. However, suspended work platforms alone are not always ideal for accessing some structures. In such cases, supported work platforms may be beneficial to provide improved access to some structures, even after suspended work platforms are in place. It may therefore be beneficial to install supported work platforms on top of suspended work platforms.

Supported or suspended access structures may require custom dimensions for specific projects due to a specific application or space constraints. Designing, manufacturing, and shipping customized components may delay completion of a project and increase overall costs. A need exists for the ability to adjust or modify already existing components to accommodate the unique criteria of a project.

DETAILED DESCRIPTION

Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems of work platform system structures and adjustable joist assemblies to adjust a length of a joist of the work platform system structures. The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways.

The technical solutions disclosed herein are directed to structural support systems (e.g., a platform), and particularly to joist assemblies configured to adjust a length of a joist for a structural support system. For example, a custom structural support system may need a custom-length joist. Instead of manufacturing different length joists for each custom structural support system, the systems disclosed herein provide joist assemblies that can be adjusted to various lengths to accommodate various different structural support systems. Having adjustable length joists may reduce time delays and increase efficiency by eliminating the need to design and manufacture different length joists for different structural support systems. The joist may be adjusted in the field to accommodate for errors in field measurements or changes in scope of work. The adjustable joist may be available sooner than a joist of a custom length that needs to be designed, manufactured, and shipped.

The joist assembly may include a first joist attachment, a second joist attachment, a joist, a first joist portion, a second joist portion, a hub (e.g., node, etc.), and/or a connector. Each component may have an interconnecting telescoping feature to facilitate a telescoping method of length adjustment. The components may be coupled together via a combination of mechanical fasteners (e.g., threaded hardware, pin, etc.) which may facilitate multiple connection points and fine adjustment. An adjusted length position may be locked in place by securing the fasteners. In some embodiments, the connector may have a plurality of openings that are spaced apart (e.g., according to a vernier scale). As the components are telescoped, the opening of the joist ends may selectively align with the openings of the connector such that a pin or other fastener can extend through the openings. The first joist attachment and the second joist attachment may be configured to stack within one another to extend the length of the joist assembly. The first joist portion and the second joist portion and/or the joist attachment and the joist may be configured to slide within one another. The joist attachment may be configured to couple to an end of a joist, to a side of a joist, or between a first joist portion and a second joist portion. Some embodiments may be configured support alternate widths of platforms. Some embodiments may be configured to replace a joist with an adjustable joist while others may be configured to extend an existing joist. Some embodiments may be configured to attach a first joist and a second joist without the use of a node.

Referring now to FIG. 1, a support structure 100, according to an example embodiment. The support structure 100 includes at least one joist 105. For example, the support structure 100 may include four joists 105. The joist 105 may be any elongate structural member adapted for bearing or supporting a load, such as a bar joist, truss, shaped-steel (i.e., I-beam, C-beam, etc.), or the like. The joists 105 are coupled together. The joists 105 are coupled together by at least one connector, shown as hub 110. The hub 110 may be any interconnection structure, such as a node, hinge, pivot, post, column, center, shaft, spindle, or the like. Any number of joists 105 may be coupled together by any number of hubs 110. In some embodiments, the joists 105 may be oriented to be coplanar. The joists 105 are oriented to support a platform 115. In the illustrated embodiment, the platform 115 is divided into a plurality of platforms, shown as platforms 116A and 116B. In some embodiments, the platform 115 is divided into a greater number of platforms 115. The support structure 100 includes a support joist 120. The support joist 120 extends between two joists 105. The support joist 120 is disposed between the plurality of platforms 115 and provide structural support to the platforms 115.

Referring now to FIG. 2, a support system 200, according to an example embodiment. The support system 200 includes a plurality of the support structures 100 of FIG. 1. The support structures 100 are coupled together at hubs 110. The support system 200 is a work platform system. In some embodiments, the support system 200 is a single support structure 100. In some embodiments, support system 200 is any structure or system which provides a substantially planar surface having at least two coplanar joists 105 or a single joist 105 configured to have two coplanar portions, where the portions are not linear with respect to each other and separated by a distance.

The size, shape, and arrangement of hubs 110 and joists 105 may vary to provide a support structure 100 and a support system 200. For example, the length of joists 105 and positioning of joists 105 and hubs 110 may vary depending on the desired size and configuration of the support system 200. While the illustrated embodiments of FIGS. 1 and 2 show that the support structures 100 are rectangular, forming an overall rectangular support system 200 with joists 105 in one direction being longer than the joists 105 extending in the opposite (e.g., perpendicular) direction, joists 105 may be any length and joined with hubs 110 at any angle permitted by the design of hubs 110.

The size and shape of the platforms 115 may similarly vary depending on the configuration of joists 105 and hubs 110. In the illustrated embodiments of FIGS. 1 and 2, the support system 200 is an access structure, such as a work platform system. Specifically, the support system 200 is a work platform system designed to be suspended from an overhead structure (e.g., a suspended work platform system). However, the support system 200 may be any support structure, including any type of access structure (e.g., suspended work platform system, supported work platform system, scaffolding, shoring). In some embodiments, the support system 200 is any structure having at least one support structure 100 having two coplanar, parallel joists 105. In some embodiments, the support system 200 is a work platform system, or a suspended work platform system. In some embodiments, the support system 200 is an articulatable suspended work platform system.

Referring now to FIG. 3, a portion of the support structure 100 of FIG. 1. The joist 105 of the support structure 100 includes an upper member 305 and a lower member 310. The upper member 305 is disposed away from the lower member 310. The upper member 305 is at least substantially parallel with the lower member 310. The joist 105 includes at least one support member 315. The support member 315 is disposed between the upper member 305 and the lower member 310. The support member 315 is disposed at an angle relative to the upper member 305 and the lower member 310. For example, the support member 315 may be diagonal relative to the upper member 305 and the lower member 310 (e.g., the support members 315 may create a truss structure, etc.). The joist 105 includes a plurality of coupling mechanisms 390 (e.g., posts, support members, etc.) configured to couple the joist 105 to the hub 110.

The joist 105 includes at least one connection point, shown as hub connection point 320. The upper member 305 and the lower member 310 each include a hub connection point 320. The joist 105 is coupled with a hub 110 via the hub connection point 320. For example, hub connection point 320 may be an opening or a pocket configured to receive a component to couple the joist 105 with the hub 110. For example, the coupling mechanism 390 may extend from a surface (e.g., a top or bottom surface) of the hub 110. The coupling mechanism 390 may be a part of the hub 110 or may be a part of a component that extends through an opening in the hub 110 (e.g., through the hub connection point 320, etc.) and beyond the top surface of the hub 110. The upper member 305 is positioned such that the hub connection point 320 receives the coupling mechanism 390 (e.g., the coupling mechanism 390 extends through the hub connection point 320, etc.). The hub connection point 320 is disposed at or approximate to an end 330 of the joist 105. For example, the hub connection point 320 may be an opening disposed at an end 330 of the upper member 305.

As shown in FIG. 3, some embodiments, the joist 105 includes at least one channel structure 335. The channel structure 335 extends along at least a portion of the joist 105. The channel structure 335 is coupled with the joist 105. For example, the channel structure 335 may be coupled with at least one of the upper member 305 or the lower member 310.

As shown in FIG. 3, the joist 105 includes at least one locating feature 340. The locating feature 340 facilitates alignment and location of the channel structure 335 with the joist 105. For example, the locating feature 340 may be configured to engage with a portion of the channel structure 335 to facilitate proper alignment and placement of the channel structure 335 relative to the joist 105. In some embodiments, the locating feature 340 is an opening in the upper member 305 or the lower member 310 of the joist 105 configured to receive a corresponding feature (e.g., a pin or post) of the channel structure 335. For example, the corresponding feature may be configured to be disposed in or extend through the locating feature 340 such that the channel structure 335 may be positioned properly relative to the joist 105. Without the locating feature 340, a channel structure 335 with such a corresponding feature may be prevented from coupling with the joist 105 or may be coupled at an undesired position or orientation.

As shown in FIG. 3, the joist 105 includes a first end 330 and a second end 332.

The third support 508 is at least substantially parallel to the first support 500 and arranged on a second side of the center axis 502 (e.g., offset from the center axis 502 in a second direction, etc.). The second side of the center axis 502 is opposite the first side of the center axis 502 (e.g., the first direction is opposite the second direction, etc.). The first support 500 is centered between the second support 504 and the third support 508. Each of the supports 498 extends between a first end and a second end, the first end opposite the second end. The first ends of the supports 498 are configured to couple to the top portion 354 and the second ends of the supports 498 are configured to couple to the bottom portion 356 of the supports 498. In some embodiments, the first support 500 is offset from the center axis 502 (e.g., the center axis 502 is centered between the second support 504 and the third support 508 and the first support 500 is offset from the center axis 502, etc.). The first support 500 defines a substantially cylindrical volume and the second support 504 and the third support 508 define substantially rectangular prism volumes.

For example, the bottom portion first apertures 572 is aligned with the top portion first apertures 532, the bottom portion second aperture 576 is aligned with the top portion second aperture 536, and so on. To continue this example, aligning the bottom portion apertures 568 with the top portion apertures 528 enables the coupling mechanism 390 to be at least substantially parallel to the first support 500 and be received within one of the bottom portion apertures 568 and one of the top portion apertures 528. In some embodiments, the bottom portion apertures 568 define a greater or lesser number of apertures (e.g., 2 apertures, 8 apertures, etc.). In some embodiments, the top portion apertures 528 are misaligned with the bottom portion apertures 568, causing the coupling mechanism 390 to form an oblique angle with the first support 500. The top portion apertures 528 and the bottom portion apertures 568 are configured to enable a user to adjust the length of the adjustable joist assembly 350 by small margins. For example, each of the top portion apertures 528 and each of the bottom portion apertures 568 may be one inch apart, which allows the user to adjust the length of the adjustable joist assembly 350 by one-inch increments.

As shown in FIG. 9, the bottom portion first piece 552 is identical (e.g., equivalent, etc.) or substantially identical to the top portion first piece 514 (e.g., appears as a mirror image, etc.). The bottom portion first piece 552 is opposite and aligned with the top portion first piece 514. The bottom portion second piece 556 is identical (e.g., equivalent, etc.) or substantially identical to the top portion second piece 518 (e.g., appears as a mirror image, etc.). The bottom portions second piece 556 is opposite and aligned with the top portion second piece 518. In some embodiments, the bottom portion first piece 552 and the bottom portion second piece 556 define a singular component. In some embodiments, the bottom portion first piece 552 and the top portion first piece 514 define alternate shapes (e.g., the bottom portion first piece 552 includes prongs and the prongs are omitted in the top portion first piece 514, etc.). In some embodiments, the bottom portion second piece 556 and the top portion second piece 518 define alternate shapes (e.g., the bottom portion second piece 556 includes prongs and the prongs are omitted in the top portion second piece 518, etc.).

As shown in FIG. 9, the joist attachment 352 includes a plurality of braces 408 (e.g., supports, etc.). Each of the braces extends between the first joist attachment end 358 and the second joist attachment end 360. The braces 408 include a first brace 602, a second brace 606, a third brace 610, and a fourth brace 614. The first brace 602 extends between the first end of the first support 500 and a center of the second support 504. The second brace 606 extends between the second end of the first support 500 and the center of the second support 504. The third brace 610 extends between the first end of the first support 500 and a center of the third support 508. The fourth brace 614 extends between the second end of the first support 500 and a center of the third support 508. In some embodiments, the joist attachment 352 includes more or less braces (e.g., two braces, eight braces, etc.). In some embodiments, the braces 408 include alternate coupling arrangements. For example, a brace may be coupled to the first end of the first support 500 and the second end of the second support 504. In another example, a brace is coupled between the first end of the first support 500 and the second end of the third support 508.

As shown in FIGS. 4-5, the adjustable joist assembly 350 of FIG. 4 is extended farther (e.g., is longer than, etc.) than in FIG. 5. In FIG. 4, the coupling mechanism 390 is coupled to the bottom portion fourth aperture 584 and the top portion fourth aperture 544. In FIG. 5, the coupling mechanism 390 is coupled to the bottom portion first aperture 572 and the top portion first aperture 532. As shown in FIGS. 4-9, the coupling mechanism 390 is configured to couple to one of the plurality of the top portion apertures 528 and one of the plurality of bottom portion apertures 568. For example, the coupling mechanism 390 is repositionable between (i) a first position where the coupling mechanism 390 is positioned within the top portion first aperture 532 and the bottom portion first aperture 572 and (ii) a second position where the coupling mechanism 390 is positioned within the top portion second aperture 536 and the bottom portion second aperture 576. To continue this example, the top portion first aperture 532 and the bottom portion first aperture 572 are located closer to the first joist attachment end 358 than the top portion second aperture 536 and the bottom portion second aperture 576 (e.g., a first distance between the top portion first aperture 532 and the first joist attachment end 358 is less than a second distance between the top portion second aperture 536 and the first joist attachment end 358). To continue this example, in the first position the first end 330 of the joist 105 is positioned a third distance from the first joist attachment end 358 and in the second position the first end 330 of the joist 105 is positioned a fourth distance from the first joist attachment end 358. The third distance is shorter than the fourth distance (e.g., the adjustable joist assembly 350 is longer in the second position than in the first position). This example may be applied to any other combination of one of the top portion apertures 528 and one of the bottom portion apertures 568.

As shown in FIG. 7, in some embodiments, the joist 105 and the joist attachment 352 are configured to rotate about the coupling mechanism 390 coupled to the hub 110.

Referring now to FIG. 8, in some embodiments, the adjustable joist assembly 350 includes joists 105 of alternate lengths. A joist 105 of one length may be modified to be a longer or shorter length using the adjustable joist assembly 350. For example, a one-sixth foot long joist 105 may be modified with a joist attachment 352 coupled on either side of the joist 105 to create a one-third foot long adjustable joist assembly 350. In another example, a one-third foot long joist 105 may be modified with a joist attachment 352 coupled on either side of the joist 105 to create a half-foot long adjustable joist assembly 350.

Referring now to FIGS. 10-14, another example of an adjustable joist assembly, also referred to as the adjustable joist assembly 350 for case of reference. FIGS. 10 and 11 show the adjustable joist assembly 350 installed in a support structure 100, according to an example embodiment. As shown in FIGS. 12 and 13, the joist attachment 352 includes a first joist attachment 370 and a second joist attachment 372. The first joist attachment 370 is configured to receive the second joist attachment 372 (e.g., the second joist attachment 372 slides within the first joist attachment 370, etc.). As shown in FIGS. 10 and 11, the first joist attachment 370 is coupled to the hub 110 in place of the joist 105. The first joist attachment 370 extends between a first joist attachment end 376 and a first joist attachment second end 378. The second joist attachment 372 extends between a second joist first end 383 and a second joist second end 384. The first joist attachment 370 includes a plurality of bars 374 (e.g., rods, pipes, tubes, etc.). The bars 374 are hollow and approximately rectangular shaped. The bars 374 each define an aperture 380 (e.g., opening, passage, channel, etc.). Each of the apertures 380 extends through the corresponding bar 374 from the first joist attachment second end 378 to a location between the first joist attachment first end 376 and a first joist attachment second end 378. In some embodiments, the plurality of bars 374 form an alternate hollow channel shape (e.g., circular, etc.).

The second joist attachment 372 includes a plurality of rods 379 (e.g., tubes, bar, pole, etc.) extending from the second joist first end 383 to a location between the second joist first end 383 and the second joist second end 384 (e.g., a tube end 386, etc.). The rods 379 are configured to be inserted into the plurality of bars 374, and the length of the rods 379 within the bars 374 may be modified to slide at various depths in or out of the bars 374 to adjust the length of the adjustable joist assembly 350, as shown in FIGS. 10 and 11. As shown in FIGS. 12 and 13, the number of rods 379 are equivalent to the number of bars 374. The adjustable joist assembly 350 includes two bars 374 and two rods 379. In some embodiments, there are more than two bars 374 and less than two rods 379.

As shown in FIGS. 12 and 13, the rods 379 and the bars 374 each define a plurality pin apertures 388. Each pin aperture 388 defined by the rods 379 is configured to align with one of the pin apertures 388 defined by the bars 374. The coupling mechanisms 390 (e.g., pins, fasteners, etc.) are received each within the pin apertures 388 in the rods 379 and the bars 374 in a direction substantially perpendicular to the length the adjustable joist assembly 350 extends. The pin apertures 388 are configured to enable a user to lock the adjustable joist assembly 350 to a desired length. FIGS. 12 and 13 show the sliding motion of the rods 379 into the bars 374 and the insertion of the coupling mechanisms 390. As shown in FIG. 14, the bars 374 on the first joist attachment 370 and the rods 379 on the second joist attachment 372 may be manufactured to be a variety of different lengths to further achieve the desired length of the joist assembly 350. The combination of manufacturing the lengths of the bars 374 and the rods 379 and the sliding length modification enabled by the pin apertures 388 enables a user to tailor the adjustable joist assembly 350 to a desired length.

Referring now to FIGS. 15 and 16, another embodiment of the adjustable joist assembly, also referred to as the adjustable joist assembly 350 for case of reference. This embodiment of FIGS. 15 and 16 is similar to the embodiment of FIGS. 10-14, however in this embodiment the first joist attachment 370 is configured to receive and straddle a joist 105. The first joist attachment 370 is configured to straddle and slidably receive the joist 105. The combination of the joist 105, the first joist attachment 370, and the second joist attachment 372 defines a heavier adjustable joist assembly 350 with increased strength (e.g., as in comparison with the adjustable joist assembly 350 of FIGS. 15 and 16, etc.). The first joist attachment 370 is configured to couple to the joist 105 and provide a back span to the joist 105 (e.g., to provide additional support and stability to the joist 105). The first joist attachment 370 is also configured to act as a clamp to the joist 105 and enable the second joist attachment 372 to cantilever towards and away from the joist 105. The first joist attachment 370 resists a fulcrum point on the joist 105 (e.g., to provide additional stability and prevent unwanted movement, etc.). The second joist attachment 372 is configured to cantilever out (e.g., telescope, etc.), up to approximately 50% of the joist 105 length. For example, the maximum cantilever length for a four-foot joist may be two feet.

As shown in FIGS. 15 and 16, the first joist attachment 370 defines a plurality of joist apertures 382. The joist apertures 382 are configured to receive a coupling mechanism 390 to couple the first joist attachment 370 to the joist 105. Each of the joist apertures 382 are disposed between two of the bars 374. The joist apertures 382 enable the coupling mechanism 390 to be received substantially perpendicular to the bars 374. The pin apertures 388 defined by the bars 374 and the rods 379 are disposed along upper surfaces of the bars 374 and the rods 379. In some embodiments, the first joist attachment includes four bars 374. In some embodiments, the first joist attachment 370 includes more or less than four apertures.

In some examples, the preferred maximum cantilever length is 6 inches to 8 inches. In some embodiments the rods 379 include a plurality of buttons (e.g., spring buttons, button clips, etc.) configured to be received within the pin apertures 388. To continue this example, the buttons are configured to be pressed down, the second joist attachment 372 pushed or pulled into or out of the aperture 380, and the buttons are configured to be released when the desired length of the adjustable joist assembly 350 is achieved. In the illustrated embodiment, the second joist attachment 372 includes four rods 379. In some embodiments, the second joist attachment 372 includes more or less than four rods 379. In some embodiments, there are more rods 379 than bars 374. In some embodiments, there are more bars 374 than rods 379.

Referring now to FIGS. 17-21, another embodiment of an adjustable joist assembly, also referred to as adjustable joist assembly 350 for ease of reference. The length of the adjustable joist assembly 350 is configured to be adjusted using a sliding motion. This embodiment is similar to the embodiment of FIGS. 15 and 16, however the rods 379 and the bars 374 are omitted, and the joist attachment 352 is configured to straddle and slide onto a portion of the joist 105 (e.g., as opposed to the first joist attachment 370 and the second joist attachment 372 coupling together to receive a joist 105). The first side portion 362 and the second side portion 364 extend from the first joist attachment end 358 to a location between the first joist attachment end 358 and the second joist attachment end 360 (e.g., to a joist attachment gap end 361, etc.). The first side portion 362 is opposite and at least substantially parallel to the second side portion 364. The joist gap 366 is further defined by between the first side portion 362, the second side portion 364, the top portion 354, the bottom portion 356, the first joist attachment end 358, and the joist attachment gap end 361.

As shown in FIGS. 18-21, the top portion 354 and the bottom portion 356 each include a plurality of flanges 368 (e.g., lips, projections, etc.). Flanges 368 extend approximately perpendicular along a length of the top portion 354 and the bottom portion 356 of the first side portion 362 and the second side portion 364 towards (e.g., within, etc.) the joist gap 366. The flanges 368 are configured to act as a channel to slidably receive the upper member 305 and the lower member 310 of the joist 105. In some embodiments, the flanges 368 extend in a direction less than or greater than 90 degrees from the first side portion 362 and the second side portion 364. For example, the upper member 305 and the lower member 310 of the joist 105 may have shapes with a cross section other than a rectangle (e.g., a triangular cross section, etc.), and the flanges 368 may be configured to be arranged to engage with the sides of the upper member 305 and the lower member 310 to facilitate slidable engagement. At least a portion of the flanges 368 are substantially flush to a side of the upper member 305 and/or the lower member 310 to facilitate slidable engagement (e.g., the plurality of flanges 368 may extend at an approximately 45-degree angle from the bottom portion 356 of the first side portion 362). As shown in FIG. 19, the adjustable joist assembly 350 includes clamps 369 (e.g., fastener, clip, etc.) configured to couple the joist 105 to the joist attachment 352.

The joist attachment 352 is a node attachment that is configured to couple to a deck support 464 and the hub 110. The adjustable joist assembly 350 is configured to enable a small addition (the deck support 464) on the side of the support structure 100, to support alternate widths of platform 115 (e.g., decking, etc.). This embodiment reduces weight in the system. For example, in other systems to extend the platform 115, additional hubs 110 and joists 105 are coupled to an edge of the system. This system removes the weight of the additional hubs 110 and joists 105 while extending the platform 115. The joist attachment 352 is configured to couple to the hub 110 at the first joist attachment end 358. The joist attachment 352 is configured to couple to the deck support 464 at the second joist attachment end 360.

Having now described some illustrative implementations, it is apparent that the foregoing is illustrative and not limiting, having been presented by way of example. In particular, although many of the examples presented herein involve specific combinations of method acts or system elements, those acts and those elements may be combined in other ways to accomplish the same objectives. Acts, elements and features discussed in connection with one implementation are not intended to be excluded from a similar role in other implementations or implementations.

The phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including” “comprising” “having” “containing” “involving” “characterized by” “characterized in that” and variations thereof herein, is meant to encompass the items listed thereafter, equivalents thereof, and additional items, as well as alternate implementations consisting of the items listed thereafter exclusively. In one implementation, the systems and methods described herein consist of one, each combination of more than one, or all of the described elements, acts, or components.

Any references to implementations or elements or acts of the systems and methods herein referred to in the singular may also embrace implementations including a plurality of these elements, and any references in plural to any implementation or element or act herein may also embrace implementations including only a single element. References in the singular or plural form are not intended to limit the presently disclosed systems or methods, their components, acts, or elements to single or plural configurations. References to any act or element being based on any information, act or element may include implementations where the act or element is based at least in part on any information, act, or element.

Any implementation disclosed herein may be combined with any other implementation or embodiment, and references to “an implementation,” “some implementations,” “one implementation” or the like are not necessarily mutually exclusive and are intended to indicate that a particular feature, structure, or characteristic described in connection with the implementation may be included in at least one implementation or embodiment. Such terms as used herein are not necessarily all referring to the same implementation. Any implementation may be combined with any other implementation, inclusively or exclusively, in any manner consistent with the aspects and implementations disclosed herein.

References to “or” may be construed as inclusive so that any terms described using “or” may indicate any of a single, more than one, and all of the described terms. References to at least one of a conjunctive list of terms may be construed as an inclusive “or” to indicate any of a single, more than one, and all of the described terms. For example, a reference to “at least one of ‘A’ and ‘B’” can include only ‘A’, only ‘B’, as well as both ‘A’ and ‘B’. Such references used in conjunction with “comprising” or other open terminology can include additional items.

Where technical features in the drawings, detailed description or any claim are followed by reference signs, the reference signs have been included to increase the intelligibility of the drawings, detailed description, and claims. Accordingly, neither the reference signs nor their absence have any limiting effect on the scope of any claim elements.

Modifications of described elements and acts such as variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, or orientations can occur without materially departing from the teachings and advantages of the subject matter disclosed herein. For example, elements shown as integrally formed can be constructed of multiple parts or elements, the position of elements can be reversed or otherwise varied, and the nature or number of discrete elements or positions can be altered or varied. Other substitutions, modifications, changes and omissions can also be made in the design, operating conditions and arrangement of the disclosed elements and operations without departing from the scope of the present disclosure.

For example, descriptions of top and bottom, upper and lower, front and back, or left and right may be reversed or interchangeable. Elements described as negative elements can instead be configured as positive elements and elements described as positive elements can instead by configured as negative elements. For example, elements described as having first polarity can instead have a second polarity, and elements described as having a second polarity can instead have a first polarity. Further relative parallel, perpendicular, vertical or other positioning or orientation descriptions include variations within +/−10% or +/−10 degrees of pure vertical, parallel or perpendicular positioning. References to “approximately,” “substantially” or other terms of degree include variations of +/−10% from the given measurement, unit, or range unless explicitly indicated otherwise. Coupled elements can be electrically, mechanically, or physically coupled with one another directly or with intervening elements. Scope of the systems and methods described herein is thus indicated by the appended claims, rather than the foregoing description, and changes that come within the meaning and range of equivalency of the claims are embraced therein. For example, the term “at least substantially parallel,” as used herein, means within +/−10% of pure parallel or pure parallel.
