TECHNICAL FIELD
This document pertains generally, but not by way of limitation, to deployable platforms attachable to or integrated with a chair to provide a writing surface or a support surface for electronic devices.
BACKGROUND
In many work settings or other meeting settings, meetings are often conducted in conference rooms having a single large table with chairs arranged the table to allow seating of a group of people around the table. The table is typically positioned at a height appropriate for people seated at the table to use the table as a writing surface or a support surface for a personal computer, a table computer, phone or other electronic device. This arrangement allows groups of seated people to meet and work around the table. However, sitting for extended periods of time is often uncomfortable, promotes adverse health effects or aggravates existing health conditions. As a result, people seated at tables for extended periods of time often stand to take breaks or alleviate physical discomfort from being seated. While standing can generally be more comfortable, the relatively low height of the table prevents users from using the table while standing without bending over. The bent over posture can similarly be physically tiring or uncomfortable, which often requires people to alternate between standing and sitting.
Certain chairs for use in conference rooms having integrated platforms that can be deployed to provide a surface for writing or electronic devices that is elevated relative to the table. The integrated platforms are typically received within the back rest and folded down to provide a substantially horizontal surface protruding from the back rest. Similarly, certain platforms have attachment mechanisms for attaching the platform to the back rest such that the platform extends from the back rest. In these configurations, the platforms rely on the balance of the chair to provide a stable platform surface when a downward force is applied to the platform surface. While chairs can ordinarily remain upright without external structural support, chairs are designed to receive the majority of the downward force applied to the chair on a seat portion centered on the chair legs. The centered seat portion and downforce operate to improve the stability of the chair. In contrast, the back rest is typically configured to provide a generally horizontal force to support a person seated on the seat portion. Accordingly, the back rest is positioned offset from the central vertical axis of the chair. However, a downward force applied to the integrated platform or attached platform protruding from the offset back rest or the weight of the platform itself can unbalance the chair. As a result, the height of the platforms is frequently positioned at a lower than optimal height to avoid unbalancing the chair. The lowered height can require a user to bend further than what is comfortable to use the platform as a writing surface or operate an electronic device on the platform.
OVERVIEW
The present inventors have recognized, among other things, that a problem to be solved can include providing a stable platform surface at an elevated height comfortably used by a standing person. In an example, the present subject matter can provide a solution to this problem, such as by a platform assembly mountable on a back rest of the chair with a mounting feature. The platform assembly can include a platform rotatable connected to a frame member engagable to the back rest of the chair by the mounting feature. The frame member can extend above the mounting feature to position the platform at a useful height, while extending below the mounting feature to engage the back rest to stabilize the platform.
In an example, the mounting feature can include a guide bracket defining a slot for slidably receiving the frame member. The frame member can be slid within the slot to adjust the vertical position of the platform. The slot can be oriented to maintain contact between the frame member and the back rest as the frame member is moved vertically to prevent rotation of the platform assembly relative to the back rest. The frame member can include a support pad to prevent marring of the back rest when the frame member is engaged to the back rest.
A platform assembly mountable on a chair having a back rest, according to an example, can include a frame element, a mounting feature and a platform. The mounting feature can be engaged to frame element. The mounting feature can be engaged to the back rest to position the frame element adjacent the back rest. The platform can have at least one support hinge rotatable connected to the frame element such that the platform is rotatable relative to the frame element between at least a deployed position and a retracted position. In the deployed position, the platform can extend transversely from the frame element. In the retracted position, the platform can be generally aligned with the frame element. The mounting feature can be positioned on the frame element such that a portion of the frame element extends above the mounting feature such that the platform is positioned above the frame element when the platform is positioned in the deployed position.
A chair, according to an example, can include a leg assembly, a seat and a back rest. The seat can positioned on the leg assembly and the back rest can be mounted on the offset from the seat. The back rest can further include a guide rail and a platform. The platform can include at least one support hinge rotatable connected to the guide rail such that the platform is rotatable relative to the guide rail between at least a deployed position and a retracted position. In the deployed position, the platform extends transversely from the guide rail. In the retracted position, the platform is generally aligned with the guide rail.
A chair, according to an example, can include a leg assembly, a seat and a rear support assembly. The seat can be positioned on the leg assembly and the rear support assembly mounted on the leg assembly offset from the seat. The rear support can further include a pair of frame members and a platform. The platform can have at least one support hinge rotatable connected to each frame member such that the platform is rotatable relative to the guide rail between at least a deployed position and a retracted position. In the deployed position, the platform extends transversely from the frame members. In the retracted position, the platform is generally aligned with the frame members in the retracted position. The frame members and platform can cooperate to define a back rest when the platform is positioned in the deployed position.
This overview is intended to provide an overview of subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the present subject matter. The detailed description is included to provide further information about the present patent application.

DETAILED DESCRIPTION
As generally depicted in FIGS. 1-5, a platform assembly 20, according to an example, can include a platform 22 mountable on a back rest of a chair such that the platform 22 can be extended from the back rest to provide a writing surface or a support surface for an electronic device. The platform assembly 20 can include the platform 22, a support hinge 24, at least one frame member 26 and at least one mounting feature 28 for mounting the platform 22 on the back rest. The frame member 26 can extend above the mounting feature 28 to position the platform 22 above the mounting feature 28 when the platform 22 is positioned to provide a writing surface or a support surface, wherein the frame member 26 stabilizes the elevated platform 22 to allow the platform 22 to be positioned vertically higher.
As depicted in FIGS. 1 and 2, the support hinge 24 can rotatably connect the platform 22 to the frame member 26 such that the platform 22 is rotatable relative to the frame member 26 between a retracted position and a deployed position. As illustrated in FIG. 1, in the retracted position, the platform 22 can be rotated to generally align with the frame member 26. In at least one example, the platform assembly 20 can include at least two frame members 26 each rotatably connected to an edge of the platform 22 by a corresponding support hinge 24 such that the platform 22 can be rotated between the frame members 26 when rotated into the retracted position. As depicted in FIG. 2, in the deployed position, the platform 22 can be rotated to extend transversely from the frame member 26. In at least one example, the platform 22 can be rotated into a substantially horizontal orientation when rotated into the deployed position to provide a surface for writing or receiving an electronic device.
As depicted in FIGS. 1 and 2, in an example, the mounting feature 28 can be mounted to the back rest of the chair such that the platform 22 extends outward from the back rest of the chair when positioned in the deployed position and substantially parallel to the back rest when positioned in the retracted position. In at least one example, the mounting feature 28 can comprise releasable features for gripping the back rest including, but not limited to a fixed hook (as illustrated in FIGS. 1 and 2), a hook adjustable to the thickness of the back rest, an adjustable claw, at least one strap and combinations thereof. In at least one example, the mounting feature 28 can comprise features for engaging features integrated into the back rest of the chair including, but not limited to mounting features 28 comprising posts insertable into corresponding receptacles integrated into the back rest.
In at least one example, the mounting feature 28 can be configured to mount the back rest such that the platform 22 extends rearward from the back rest as depicted in FIG. 2. In at least one example, the mounting feature 28 can be configured to mount the back rest such that the platform 22 extends forward from the back rest over the seat rest as depicted in FIG. 3. In at least one example, the mounting feature 28 can be configured to allow the platform 22 to be swapped between the forward mounted position and the rear mounted position.
As depicted in FIGS. 1 and 2, in an example, the platform 22 can define a top surface 38 and a bottom surface 40. The top surface 38 can provide a planar writing surface or support surface for receiving an electronic device when the platform 22 is rotated into the deployed position as depicted in FIG. 2. In an example, the top surface 38 can include integrated features including, but not limited to, non-slip coatings, mouse pad, recesses, or elevated features for receiving an electronic device and combinations thereof. In certain examples, the top surface can include a resilient, durable, or hard material, such as can be configured for use as a work surface or as a electronic device support surface.
As depicted in FIG. 2, in at least one example, the mounting feature 28 can be configured to mount on the back rest such that the platform 22 extends rearward from the chair. As depicted in FIG. 3, in at least one example, the mounting feature 28 can be configured to mount on the back rest such that the platform 22 extends forward from the back rest of the chair such that the platform 22 is positioned over a seat rest of the chair.
As depicted in FIGS. 1 and 2, in an example, the frame member 26 can be mounted to the mounting feature 28 such that the frame member 26 engages the back rest to prevent rotation of the platform assembly 20 about the mounting feature 28. The frame member 26 can also cooperate with the mounting feature 28 to translate a downward force applied to the platform 22 to a horizontal force supported by the back rest. In at least one example, the frame member 26 can include a support pad 30 positioned to engage the back rest. The support pad 30 can comprise a rubber, foam, elastomer, plastic or other material for releasably engaging the back rest without damaging the material of the back rest.
As depicted in FIG. 4, in an example, the platform 22 can further include at least one support member 32 and a corresponding secondary hinge 34. The secondary hinge 34 can rotatably connect the support member 32 to the platform 22 such that the support member 32 can be rotated relative to the platform 22 between a support position and a retracted position. In the support position, the support member 32 extends transversely from the platform 22 to engage the frame member 26 or the back rest of the chair to maintain the platform 22 in the deployed position, as illustrated in FIG. 4. In an example, the support member 32 can be releasably engaged to the frame member 26 to maintain the platform 22 in the desired rotational position. The support member 32 and frame member 26 can be releasably secured with a hook and pin configuration, removable pin and hook or opening configuration, a spring loaded pin and detent configuration or other releasable engagement configuration. In the retracted position, the support member 32 can be rotated into alignment with the platform 22 permitting rotation of the platform 22 into the retracted position. In at least one example, the platform 22 defines a recess for receiving the support member 32 when the support member 32 is rotated into the retracted position. In at least one example, when the platform 22 is positioned in the retracted position, the support member 32 can be disengaged from the platform 22 and stored within the recess or removed from the assembly. The secondary hinge 34 can include a removable feature that can be removed by a tool or incorporates a quick release feature.
As depicted in FIG. 5, in an example, the support member 32 can support the platform 22 without a frame member 22. In this configuration, the support hinge 24 can be mounted to the mounting feature 28 such that the platform 22 rotates about the mounting feature 28. In at least one example, the support member 32 can further include a support pad 36 positioned to engage the back rest. The support pad 36 can comprise a rubber, foam, elastomer, plastic or other material for releasably engaging the back rest without damaging the material of the back rest.
As depicted in FIGS. 6 and 7, in an example, the platform 22 can include a support bracket 42 mountable to the bottom surface 40 of the platform 22. The support bracket 42 can be rotatably engaged to the support hinge 24 to mount the platform 22 to the support hinge 24. In at least one example, the support bracket 24 can be sized to position the platform 22 above the mounting feature 28 when the platform 22 is rotated into the deployed position. In an example, the support bracket 42 can be positioned on the bottom surface 40 adjacent an edge of the platform 22. In another example, the support bracket 42 can be positioned inward from an edge of the platform 22. In this configuration, a portion of the platform 22 extends over the back rest of the chair, as depicted in FIG. 7. The more centered position of the support bracket 42 and correspondingly the support hinge 24 improves stability of the platform 22 when the platform 22 is rotated into the deployed position and elevated above the mounting feature 28.
As depicted in FIGS. 7 and 8, in an example, the mounting feature 28 can include a guide bracket 44 defining a slot 46 for slidably receiving the frame member 26. In this configuration, the frame member 26 is within the slot 46 between at least a lowered position, as depicted in FIG. 7, and an elevated position, as depicted in FIG. 8, to position the platform 22 at different vertical heights. In at least one example, the slot 46 can be oriented such that the platform 22 moves horizontally as the platform 22 is moved vertically on the frame member 26. In at least one example, the slot 46 can be oriented such that the platform 22 only moves vertically on the frame member 26.
As depicted in FIGS. 7 and 8, in an example, the frame member 26 can be guided by the slot 46 of the guide bracket 44 such that the frame member 26 engages the back rest to prevent rotation of the platform assembly 20 about the mounting feature 28 as the frame member 26 is slid in the slot 46 and when the platform 22 is being elevated or lowered vertically. In at least one example, the slot 46 is oriented to maintain engagement of the frame member 26 with the back rest as the frame member 26 is slid within the slot 46. The frame member 26 can also cooperate with the mounting feature 28 to translate a downward force applied to the platform 22 to a horizontal force supported by the back rest. The engagement of the frame member 26 to the back rest permits elevation of the platform 22 substantially above the mounting feature 28 in part by translating the offset downward force applied to the platform 22 to the back rest.
As depicted in FIGS. 7 and 8, in an example, the guide bracket 44 can further include a locking element 48 for releasably engaging the frame member 26 to fix the position of the frame member 26. The locking element 48 can be configured to engage the locking element 48 to prevent vertical adjustment of the height of the platform 22. In at least one example, the locking element 48 can include a threaded stopper rotated by knob. In this configuration, the knob can be manually rotated to rotate the threaded stopper into engagement with the frame member 26 to apply a frictional force preventing movement of the frame member 26 or out of engagement with the frame member 26 to permit sliding of the frame member 26. In other examples, the locking element 36 can include, but is not limited to, a spring biased pin, removable locking pin and other releasable locking element for releasably engaging the frame member 26.
As generally depicted in FIG. 9-12, a chair 50, according to an example, can include a platform 52 integrated into a back rest 54 of the chair 50 such that the platform 52 can be deployed from the back rest 54 to provide a writing surface or a support surface for an electronic device. In an example, the chair 50 can include the platform 52, the back rest 54, a seat 56 and a leg assembly 58. As illustrated in FIGS. 9 and 10, the leg assembly 58 can be mounted to the underside of the seat 56 and the back rest 54 can be mounted to the leg assembly 58 such that the back rest 54 is offset from the seat 56. In at least one example, the leg assembly 58 can include a height adjustment assembly (e.g., a pneumatic mechanism) such that height of the leg assembly 58 can be adjusted to change the vertical height of the platform 52. In at least one example, the back rest 54 can be configured to have a standard specified height corresponding to a height for an average person. The description and depiction of the seat 56 and the leg assembly 58 is not intended to be limiting, but rather to assist in the description of the integrated platform 52 according to the present example.
As depicted in FIGS. 9-10, according to an example, the back rest 54 further includes at least one guide rail 60. The platform 52 further includes a support hinge 62 rotatably mounted to the guide rail 60 such that the platform 52 is rotatable relative to the guide rail 60 between a deployed position and a retracted position. As illustrated in FIG. 9, in the retracted position, the platform 52 can be rotated to generally align with the guide rail 60. In at least one example, the back rest 54 can include at least two guide rail 60 each rotatably connected to an edge of the platform 52 by a corresponding support hinge 62 such that the platform 52 can be rotated between the guide rail 60 when rotated into the retracted position. In at least one example, each guide rail 60 is positioned within a platform housing receptacle with the back rest 54 such that the platform 52 is received within the platform housing receptacle when rotated into the retracted position. The platform housing receptacle can conceal or hide the platform 52 when the platform 52 is not in use. As depicted in FIG. 10, in the deployed position, the platform 22 can be rotated to extend transversely from the guide rail 60 and correspondingly the back rest 54. In at least one example, the platform 52 can be rotated into a substantially horizontal orientation when rotated into the deployed position to provide a surface for writing or receiving an electronic device such that an electronic device can be rested or positioned on top of the platform.
As depicted in FIGS. 10 and 11, in at least one example, the support hinge 62 can be configured to permit rotation of the platform 52 such that the platform 52 extends rearward from the back rest 54 as depicted in FIG. 10 In at least one example, the support hinge 62 can be configured to permit rotation of the platform 52 such that the platform 52 extends forward from the back rest 54 to extend over the seat 56 as depicted in FIG. 11. The forward orientation can improve the stability of the platform 52 by centering the weight of the platform 52 and objects thereon over the leg assembly 58. The forward orientation can also reduce the overall footprint of the chair 50 when the platform 52 is positioned in the deployed position. The support hinge 62 can have a releasable locking feature for fixing the platform 52 at the reward orientation or the forward orientation as the platform 52 is rotated from the retracted position to either the forward or rearward deployed position.
As depicted in FIGS. 9 and 10, in an example, the guide rail 60 defines a track for slidably receiving the support hinge 62. The support hinge 62 can be slid within the track to elevate or lower the platform 52. In at least one example, the support hinge 62 can be slid within the track to lower the front edge of the platform 52 as the platform 52 is folded into the retracted position as illustrated in FIG. 9. Similarly, the support hinge 62 can be slid within the track to elevate the front edge of the platform 52 as the platform 52 is rotated into the deployed position as illustrated in FIG. 10.
As depicted in FIGS. 13 and 14, in an example, the platform 52 can further include at least one support member 64 and a corresponding secondary hinge 66. The secondary hinge 66 can rotatably connect the support member 64 to the platform 52 such that the support member 64 can be rotated relative to the platform 52 between a support position and a retracted position. In the support position, the support member 64 extends transversely from the platform 52 to engage the guide rail 60 or the back rest 54 of the chair 50 to maintain the platform 52 in the deployed position, as illustrated in FIG. 13. In an example, the platform 52 can include a support pad 68 for engaging the back rest 54 without marring the back rest 54. When the platform 52 is positioned in a forward deployed position, the support member 64 can be extended to engage the front side of the back rest 54. In an example, the support member 64 can be releasably engaged to the guide rail 60 to maintain the platform 52 in the desired rotational position. The support member 64 and guide rail 60 can be releasably secured with a hook and pin configuration, removable pin and hook or opening configuration, a spring loaded pin and detent configuration or other releasable engagement configuration. In the retracted position, the support member 64 can be rotated into alignment with the platform 52 permitting rotation of the platform 52 into the retracted position. In at least one example, the platform 52 defines a recess for receiving the support member 64 when the support member 64 is rotated into the retracted position. In at least one example, when the platform 52 is positioned in the retracted position, the support member 64 can be disengaged from the platform 52 and stored within the recess or removed from the assembly.
As generally depicted in FIGS. 14-22, a chair 70, according to an example, can include a platform 72 that can be positioned to operate as a back rest and repositioned to operate as a writing surface or a support surface for an electronic device. In an example, the chair 70 can include a platform 72, a rear support assembly 74, a seat 76 and a leg assembly 78. As illustrated in at least FIGS. 14 and 15, the leg assembly 78 can be mounted to the underside of the seat 76 and the rear support assembly 74 can be mounted to the leg assembly 78 such that the rear support 74 is offset from the seat 76. The description and depiction of the seat 76 and the leg assembly 78 is not intended to be limiting, but rather to assist in the description of the integrated platform 72 according to the present example.
As depicted in FIGS. 14 and 15, the rear support assembly 74 includes a rear support 80, a first frame member 82A and a second frame member 82B. The platform 72 includes a first support hinge 84A rotatably engagable to the first frame member 82A and a second support hinge 84B rotatably engagable to the second frame member 84B such that the platform 72 is rotatable with respect to the first and second frame members 82A, 82B.
As depicted in FIGS. 14-16, the platform 72 is rotatable with respect to the first and second frame members 82A, 82B between a deployed position and a retracted position. As illustrated in FIGS. 14 and 15, in the retracted position, the platform 72 can be rotated to generally align with the first and second frame members 82A, 82B. In at least one example, the first frame member 82A further includes a first support bracket 86A for engaging the platform 72 when the platform 52 is rotated into the retracted position. The second frame member 82B can also further include a second support bracket 86B for engaging the platform 52 when the platform 52 is rotated into the retracted position. Each support bracket 86A, 86B can be engaged to the platform 72 to prevent rotation of the platform 72 past the retracted position such that the platform 72 can provide back support for a person seated on the seat 76. As depicted in FIG. 16, in the deployed position, the platform 72 can be rotated to extend transversely from the frame members 82A, 82B. In at least one example, the deployed position can have a substantially horizontal orientation to provide a surface for writing or receiving an electronic device.
As depicted in FIG. 17-19, in at least one example, the support hinges 84A, 84B can be configured to permit rotation of the platform 72 such that the platform 72 extends rearward from the frame members 82A, 82B as illustrated in FIGS. 17 and 18. In at least one example, the support hinges 84A, 84B can be positioned such that at least a portion of the platform 72 is positioned forward of the frame members 82A, 82B. The forward portion of the platform 72 balances the portion of the platform 72 that extends rearward of the frame members 82A, 82B. In at least one example, the support hinges 84A, 84B can be configured to permit rotation of the platform 72 such that the platform 72 extends forward from the frame members 82A, 82B as illustrated in FIG. 19. In this configuration, the platform 72 is positioned over the seat 76.
As depicted in FIGS. 18 and 19, in an example, the platform 72 can further include at least one front support member 88 and a corresponding front hinge 90. The front hinge 90 can rotatably connect the front support member 90 to a portion of the platform 72 forward of the frame members 82A, 82B and at least one of frame members 82A, 82B to maintain the platform 52 in the deployed position, as illustrated in FIGS. 18 and 19. In at least one example, the front hinge 90 allows the front support member 88 to rotate relative to the platform 72 between a support position and a retracted position. In the support position, the front support member 88 extends transversely from the platform 72 to engage the frame members 82A, 82B in the deployed position. The front support member 88 and frame members 82A, 82B can be releasably secured with a hook and pin configuration, removable pin and hook or opening configuration, a spring loaded pin and detent configuration or other releasable engagement configuration. In the retracted position, the front support member 88 can be rotated into alignment with the platform 72 permitting rotation of the platform 72 into the retracted position. In at least one example, the platform 72 defines a recess for receiving the front support member 88 when the front support member 88 is rotated into the retracted position. In at least one example, when the platform 72 is positioned in the retracted position, the front support member 88 can be disengaged from the platform 52 and stored within the recess or removed from the assembly.
As depicted in FIGS. 20 and 21, in an example, the platform 72 can further include at least one rear support member 92 and a corresponding rear hinge 94. The rear hinge 94 can rotatably connect the front support member 90 to a portion of the platform 72 rearward of the frame members 82A, 82B and at least one of frame members 82A, 82B to maintain the platform 52 in the deployed position, as illustrated in FIG. 21. In at least one example, the rear hinge 94 allows the rear support member 92 to rotate relative to the platform 72 between a support position and a retracted position. In at least one example, the rear hinge 94 can be disengaged allowing the rear support member 92 to be separated from the platform 72.
As depicted in FIGS. 22 and 23, in at least one example, the first and second support brackets 86A, 86B can be oriented such that the platform 72 can be rotated forward toward the seat 76 until positioned in the deployed position. As depicted in FIG. 23, the first and second support brackets 86A, 86B can be oriented such that the platform 72 can be rotated rearward away from the seat 76 until positioned in the deployed position. In either configuration, the deployed position can position the platform 72 in a substantially horizontal orientation to provide a surface for writing or receiving an electronic device.
As depicted in FIG. 23, in an example, the platform 72 can further include at least one support member 88 and a corresponding secondary hinge 90. The secondary hinge 90 can rotatably connect the support member 88 to the platform 72 such that the support member 88 can be rotated relative to the platform 72 between a support position and a retracted position. In the support position, the support member 88 extends transversely from the platform 72 to engage the frame members 82A, 82B. In an example, the support member 88 can be releasably engaged to the frame members 82A, 82B to maintain the platform 72 in the desired rotational position. The support member 88 and frame members 82A, 82B can be releasably secured with a hook and pin configuration, removable pin and hook or opening configuration, a spring loaded pin and detent configuration or other releasable engagement configuration. In the retracted position, the support member 88 can be rotated into alignment with the platform 72 permitting rotation of the platform 72 into the retracted position. In at least one example, the platform 72 defines a recess for receiving the support member 88 when the support member 88 is rotated into the retracted position. In at least one example, when the platform 72 is positioned in the retracted position, the support member 88 can be disengaged from the platform 72 and stored within the recess or removed from the assembly. The secondary hinge 90 can include a removable feature that can be removed by a tool or incorporates a quick release feature.
Each of these non-limiting examples can stand on its own, or can be combined in any permutation or combination with any one or more of the other examples.
The above detailed description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show, by way of illustration, specific embodiments in which the present subject matter can be practiced. These embodiments are also referred to herein as “examples.” Such examples can include elements in addition to those shown or described. However, the present inventors also contemplate examples in which only those elements shown or described are provided. Moreover, the present inventors also contemplate examples using any combination or permutation of those elements shown or described (or one or more aspects thereof), either with respect to a particular example (or one or more aspects thereof), or with respect to other examples (or one or more aspects thereof) shown or described herein.
In the event of inconsistent usages between this document and any documents so incorporated by reference, the usage in this document controls.
In this document, the terms “a” or “an” are used, as is common in patent documents, to include one or more than one, independent of any other instances or usages of “at least one” or “one or more.” In this document, the term “or” is used to refer to a nonexclusive or, such that “A or B” includes “A but not B,” “B but not A,” and “A and B,” unless otherwise indicated. In this document, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Also, in the following claims, the terms “including” and “comprising” are open-ended, that is, a system, device, article, composition, formulation, or process that includes elements in addition to those listed after such a term in a claim are still deemed to fall within the scope of that claim. Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects.
The above description is intended to be illustrative, and not restrictive. For example, the above-described examples (or one or more aspects thereof) may be used in combination with each other. Other embodiments can be used, such as by one of ordinary skill in the art upon reviewing the above description. The Abstract is provided to comply with 37 C.F.R. §1.72(b), to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. Also, in the above Detailed Description, various features may be grouped together to streamline the disclosure. This should not be interpreted as intending that an unclaimed disclosed feature is essential to any claim. Rather, inventive subject matter may lie in less than all features of a particular disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description as examples or embodiments, with each claim standing on its own as a separate embodiment, and it is contemplated that such embodiments can be combined with each other in various combinations or permutations. The scope of the present subject matter should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
