[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 044,034, filed June 25, 2020, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to an angled saw configured to make angled cuts in a workpiece. Background Technology

[0004] An angle saw can be used to make beveled or angled cuts on a workpiece. Traditional angle saws include conventional angle guides, which allow the angle of the bevel cut to vary selectively. In many traditional angle saws, the cutting position of the circular saw blade entering the workpiece varies with the angle relative to the rest of the angle saw. Any cutting guide in such a traditional angle saw can only precisely represent a cutting position suitable for a single angle, and / or the angle saw may include multiple cutting guides, each referencing a given angle. While effective for imprecise cuts, such traditional angle saws make it difficult to precisely cut workpieces at a variety of different angles. Therefore, there is a need for improved angle saws configured to make bevel cuts on workpieces. Summary of the Invention

[0005] This document discloses a bevel saw for making bevel cuts in a workpiece. The bevel saw includes a motor with a motor shaft configured to rotate about an axis of rotation. The bevel saw also includes a spindle configured to operably attach a circular saw blade to the bevel saw, and / or to rotate the circular saw blade in a saw blade plane and / or about the spindle's axis of rotation when the spindle receives torque from the motor via rotation of the motor shaft about the axis of rotation. The bevel saw also includes a base plate defining a spindle-facing side and a spindle-reverse side. The spindle is operably attached to the spindle-facing side of the base plate such that the spindle-facing side of the base plate faces the spindle. The bevel saw also includes a bevel guide configured to selectively change the bevel angle between the saw blade plane and the spindle-reverse side of the base plate within an angular range of bevel cutting motion, thereby selectively changing the angle of the bevel cut within the workpiece.

[0006] In some examples, the beveled guide includes a guide plate comprising a first arcuate slot and a second arcuate slot. The first arcuate slot has a first radius of curvature extending from a first origin. The second arcuate slot has a second radius of curvature extending from a second origin spaced apart from the first origin.

[0007] In some examples, the bevel saw includes a bevel guide mount configured to operatively attach the bevel guide to the substrate. The bevel guide mount includes a single bevel guide mount fastener that operatively attaches the bevel guide to the substrate. The bevel guide mount also includes a reinforcing structure defining an opening. The bevel guide mount fastener extends through the opening such that the bevel guide is pressed between the reinforcing structure and the substrate. The bevel guide mount fastener includes a bevel guide mount fastener head defining a fastener head transverse cross-sectional area, and the contact area between the reinforcing structure and the bevel guide is at least 10 times the transverse cross-sectional area of ​​the fastener head.

[0027] Typically, elements that may be included in a particular embodiment are shown in solid lines, while optional elements are shown in dashed lines. However, elements shown in solid lines may not be necessary for all embodiments, and in some embodiments may be omitted without departing from the scope of this disclosure.

[0028] Figure 1 This is a schematic front view illustrating an example of the bevel saw 10 according to the present disclosure, and illustrates the first bevel angle 613, while Figure 2 The diagram shows the second oblique angle 614. Figure 1 Another schematic front view of the beveled saw. Figure 3 yes Figure 1-2 A schematic side view of an angled saw, and Figure 4-13 This is a non-simplified illustration of an example of the bevel saw 10 according to this disclosure. More specifically, Figure 4 The figure shows a top outline view of the bevel saw 10. Figure 5 The figure shows a right-side view of the bevel saw 10. Figure 6 The figure shows a left-side view of the bevel saw 10, with the bevel saw positioned at insertion point 52. Figure 7 The figure shows a left-side view of the bevel saw 10, illustrating the bevel saw in its retracted position 54, and... Figure 8 The diagram shows Figure 7 The left-hand view shows that several overlays have been removed. Figure 9 This is a front view of the bevel saw 10 with the first bevel angle 613. Figure 10 This is the rear view of the bevel saw 10, and... Figure 11 This is a top view of the angled saw 10. Figure 12 This is a bottom view of the angled saw 10, and Figure 13 This is another front view of the bevel saw 10, showing the second bevel angle 614.

[0029] As by Figure 1-13 As generally shown, the bevel saw 10 includes a motor 90, which includes a motor shaft 92 configured to rotate about a rotation axis 94. The bevel saw 10 also includes a spindle 100 configured to receive torque from the motor 90 when the motor shaft 92 rotates about the rotation axis. Receiving torque causes the spindle 100 to rotate about the spindle rotation axis 102.

[0030] like Figures 1 to 3 The dashed lines in the middle and Figures 5 to 10 and Figures 12 to 13 As shown by the solid lines, the bevel saw 10 may also include a circular saw blade 200. The circular saw blade 200 (when present) may be operably attached to the bevel saw via a spindle 100 and / or may be configured to rotate with the spindle. In other words, rotation of the spindle 100 (such as about the spindle rotation axis 102) can cause the circular saw blade 200 to rotate, such as within the saw blade plane 202. Figure 1-3 , Figure 5-10 and Figure 12-13 As shown in the diagram. The rotation of the circular saw blade 200 facilitates cutting the workpiece 98 with the circular saw blade, as... Figure 1-3 As shown schematically in the diagram.

[0031] The bevel saw 10 also includes a substrate 304 that defines a mandrel-facing side 308 and a mandrel-repellent side 312. The mandrel 100 is operatively attached to the mandrel-facing side 308 such that the mandrel-facing side of the substrate faces the mandrel.

[0032] The bevel saw 10 also includes a bevel guide 600, which can be configured to selectively change the bevel angle 612 between the saw blade plane 202 and the back-to-center side 312 of the base plate 304, so as to selectively change the angle at which the bevel saw is configured to perform a bevel cut 99 within the workpiece 98, such as... Figure 1-2 As shown in the diagram. This can include selective variations within the range of beveled cutting motion angles, such as, for example, […]. Figure 1 and Figure 9 The first oblique angle 613 and and Figure 2 and Figure 13 The second bevel angle 614 is defined between. Examples of bevel cutting motion angle ranges include angle ranges of at least 25 degrees, at least 30 degrees, at least 35 degrees, at least 40 degrees, at least 45 degrees, up to 70 degrees, up to 65 degrees, up to 60 degrees, up to 55 degrees, up to 50 degrees, and / or up to 45 degrees. As discussed in more detail herein, the bevel guide 600 can be operatively attached to the substrate 304 by means of, via, and / or using the bevel guide mount 700.

[0033] The bevel saw 10 may include any suitable type or style of bevel saw adapted, configured, designed, and / or constructed to cut workpieces using the circular saw blade 200. In other words, according to this disclosure, the bevel saw 10 may include additional features that may not be necessary for all bevel saws 10. Examples of such bevel saws 10 with additional features include handheld bevel saws 12, insert saws 30, and / or track saws 40, such as... Figure 1-3 As schematically illustrated herein, the bevel saw 10 may include structures and / or features from two or more of the aforementioned saws, and / or may incorporate the functionality of two or more of the aforementioned saws. As an example and as discussed in more detail herein, a given bevel saw 10 may be and / or may incorporate the functionality of a handheld bevel saw 12, an insert saw 30, and / or a track saw 40. Therefore, the bevel saw 10 according to this disclosure may include one or more features disclosed herein, but the bevel saw 10 need not include all features disclosed herein.

[0034] Motor 90 may include any suitable structure that can power the rotation of motor shaft 92 and / or the drive of circular saw blade 200. Examples of motor 90 include electric motors, AC electric motors, DC electric motors, brushless DC motors, variable speed motors, and / or single speed motors.

[0035] like Figure 1-3The dashed lines in the middle and Figure 4 , Figure 6-8 and Figure 10-11 As shown by the solid lines, the bevel saw 10 may include a gripping area 60 configured to be gripped and / or held by a user during operation of the bevel saw. The gripping area 60 (when present) may also be referred to herein as and / or may be a handle or grip.

[0036] For example Figures 1 to 3 The dashed lines in the middle and Figure 4 and Figures 6 to 8 As shown by the solid lines, the angle saw 10 may include at least one switch 65. Switch 65 (when present) may be configured to be selectively actuated by a user of the angle saw to enable and / or allow the supply of current to at least one other component of the angle saw and / or allow power operation of at least one other component of the angle saw. For example, selective actuation of switch 65 may be used to operate the motor controller of the angle saw to selectively apply current to the motor 90, enabling the motor controller to selectively apply current to the motor and / or allow or direct the motor to provide power for rotation of the motor shaft.

[0037] In some examples, the current may be used to power at least one other component of the bevel saw (such as motor 90) or directly power at least one other component of the bevel saw (such as motor 90). In some such examples, the current may also be referred to herein as an electrical power signal. In some examples, the current may be an electrical data signal sent to at least one other component of the bevel saw (such as the motor controller of the bevel saw). In some such examples, the current may also be referred to herein as a data signal and / or an electrical data signal. Examples of switch 65 include an electric switch, a normally open electric switch, a momentary electric switch, and / or a locked momentary electric switch.

[0038] The angled saw 10 may include any suitable power source and corresponding power structure for powering the motor 90. Examples of power structures include a power supply structure 70, such as a power cord 72 and / or a battery 74, as... Figure 1-3 As shown.

[0039] For example Figure 1-3 The dashed lines in the middle and Figure 4-13 As shown by the solid lines, the bevel saw 10 may include a blade guard 80. The blade guard 80 (when present) may be configured to cover, receive, and / or contain at least one area of ​​the circular saw blade 200 to prevent or reduce the likelihood of contact between the user and the circular saw blade. In some examples of the bevel saw 10, the blade guard 80 may include a retractable area. The retractable area may be configured to fold, rotate, and / or otherwise retract when the bevel saw is used to cut a workpiece. The retractable area may additionally or alternatively be referred to as a retracted area and / or a collapsed area.

[0040] In some examples, and as discussed, the bevel saw 10 may include or may be an insert saw 30. In examples where the bevel saw 10 includes or is an insert saw 30, the mandrel 100 may be configured to move relative to the substrate 304 to selectively change the region 320 of the circular saw blade 200 protruding from the substrate and / or selectively change the cutting depth of the bevel saw. The mandrel 100 may be operably attached to the mandrel-facing side 308 of the substrate 304 via and / or using a substrate pivot 316, as... Figure 1-3 The dashed lines in the middle and Figure 6-8 as well as Figure 11-12 As shown by the solid lines in the figure. In some examples, the spindle 100 and the substrate 304 can be configured to rotate relative to each other about a substrate pivot 316 in order to selectively change the region 320 of the circular saw blade 200 extending on the side of the substrate away from the spindle 312, as may be done by means of the positioning 52 inserted from the figure. Figure 1-3 , Figure 5-6 , Figure 9-10 and Figure 13 The configuration shown is aligned with the illustrated retraction positioning 54. Figure 7-8 The configuration changes shown are best illustrated as described.

[0041] In other words, the spindle 100 can be configured to pivot relative to the base plate 304 over a range of relative positioning or relative angles, which can be defined by insertion positioning and retraction positioning. For each relative positioning within this range, the circular saw blade 200 can extend a corresponding amount on the side away from the spindle 312, thereby providing a corresponding maximum cutting depth for the bevel saw.

[0042] In some examples, and as discussed, the bevel saw 10 may include or may be a track saw 40. In examples where the bevel saw 10 includes or may include a track saw 40, the substrate 304 may include a rib receiving channel 324, which may be configured to receive the raised elongated ribs 44 of the track 42, such as... Figure 1-2 As best illustrated herein. The track 42 may also be referred to herein as an elongated track 42, and may be formed from one or more elongated track segments or track portions 46, which may be operably attached to each other to define any suitable track length. During operation of the track saw 40, the track 42 may be operably attached or clamped to the workpiece 98 such that the edge of the track corresponds to the desired cutting line of the track saw. Subsequently, the track saw may be positioned relative to the track such that the raised elongated ribs 44 are positioned within the rib receiving channel 324; and the track saw may then be translated along at least a portion of the length of the elongated track, thereby producing a straight cut along the desired cutting line.

[0043] Figure 1-3An example of a bevel saw 10 including a bevel guide 600 according to this disclosure is schematically shown, and Figure 13-15 This is a non-simplified illustration emphasizing an example of the components of the beveled saw 10 according to the example of the beveled guide 600 of this disclosure. Figure 1-3 Indicatively and Figure 14-15 As shown in a simplified representation, the angled guide 600 may include a guide plate 622. The guide plate 622 may include a first arcuate slot 628 and a second arcuate slot 640. (As...) Figure 1-3 and Figure 15 As shown, the first arcuate slot 628 may have a first radius of curvature 632 extending from the first origin 636. Similarly, the second arcuate slot 640 may have a second radius of curvature 644 extending from the second origin 648. The second origin 648 is spaced apart from the first origin 636. Therefore, the first arcuate slot 628 and the second arcuate slot 640 may be referred to herein as and / or may be non-concentric arcuate slots.

[0044] Both the first radius of curvature and the second radius of curvature can be greater than zero or have a non-zero value. Furthermore, the first radius of curvature 632 can be different from the second radius of curvature 644. As an example, the ratio of the first radius of curvature to the second radius of curvature can be at least 1.25, at least 1.5, at least 1.75, at least 2, at least 2.25, at least 2.5, at least 2.75, at least 3, at least 3.25, at least 3.5, at least 3.75, at least 4, up to 6, up to 5.5, up to 5, up to 4.5, up to 4, up to 3.5, and / or up to 3. The first radius of curvature and / or the second radius of curvature can have and / or be defined by any arbitrary size. Examples of the size of the first radius of curvature and / or the second radius of curvature include at least 25 mm, at least 30 mm, at least 35 mm, at least 40 mm, at least 45 mm, at least 50 mm, at least 55 mm, at least 60 mm, at least 65 mm, at least 70 mm, at least 75 mm, at least 80 mm, at least 85 mm, at least 90 mm, at least 95 mm, at least 100 mm, at most 200 mm, at most 175 mm, at most 150 mm, at most 125 mm, at most 100 mm and / or at most 75 mm.

[0045] The second origin can be spaced apart from the first origin by any suitable amount. As an example, the distance between the first and second origins can be at least a threshold fraction of the first radius of curvature. Examples of threshold fractions of the first radius of curvature include at least 1%, at least 2.5%, at least 5%, at least 7.5%, at least 10%, at least 12.5%, up to 50%, up to 40%, up to 30%, up to 20%, up to 15%, and / or up to 10%.

[0046] In some examples, and continue to refer to Figure 1-3 and Figure 14-15 The bevel guide 600 may include a plurality of pins 652, including at least a first pin 656 and at least a second pin 660. The first pin 656 may be configured to operably translate along a first arcuate slot 628 as the bevel angle 612 selectively varies throughout the entire range of bevel cutting angle movement. Similarly, the second pin 660 may be configured to operably translate along a second arcuate slot 640 as the bevel angle selectively varies throughout the entire range of bevel cutting angle movement.

[0047] The mandrel of the angle saw can be operably attached to one of the guide plate 622 and the pin 652, and the base plate of the angle saw can be operably attached to the other of the guide plate and the pin 652. Additionally, multiple pins and the guide plate together attach the mandrel to the base plate. Considering the above, during changes in the angle 612, the guide plate 622 and the pin 652 together can be used to orient or position the base plate and the mandrel, motor, and / or the angle saw blade relative to each other.

[0048] In some examples, and such as Figure 1-3 and Figure 14-15 As shown by the dashed lines, the beveled guide 600 may include a plurality of bushings 670, such as a first bushing 672 and a second bushing 674. The first bushing 672 (when present) may extend around at least one region of a first pin 656 extending within a first arcuate slot 628. In some examples, the first bushing may extend between the first pin and the first arcuate slot and / or may be configured to separate the first pin and the first arcuate slot or maintain a spaced-apart relationship between the first pin and the first arcuate slot. In some examples, the first bushing may be configured to rotate around the first pin 656 and / or within the first arcuate slot 628. Similarly, the second bushing 674 (when present) may extend around at least one region of a second pin 660 extending within a second arcuate slot 640. In some examples, the second bushing may extend between the second pin and the second arcuate slot and / or may be configured to separate the second pin and the second arcuate slot or maintain a spaced-apart relationship between the second pin and the second arcuate slot. In some examples, the second bushing may be configured to rotate about the second pin 660 and / or within the second arcuate slot 640. This configuration may reduce friction and / or wear within the bevel guide 600, and / or make it easier for the user to adjust the bevel saw throughout the angular range of the bevel cutting motion.

[0049] In some examples of the bevel saw 10, and as... Figure 3As shown, the bevel saw may include a plurality of bevel guides 600, including at least a front bevel guide 604 and a rear bevel guide 608. Such a configuration can increase the rigidity and / or accuracy of the bevel guides and / or reduce the possibility of unintended changes in angle 612. In some such configurations, the bevel saw 10 may also include a front bevel guide mount 702 and a rear bevel guide mount 704, the front bevel guide mount 702 being configured to operatively attach the front bevel guide 604 to the front region 305 of the substrate 304, and the rear bevel guide mount 704 being configured to operatively attach the rear bevel guide 608 to the rear region 306 of the substrate.

[0050] The front bevel guide 604 and the rear bevel guide 608 may include similar structures, such as those discussed herein with reference to bevel guide 600. As an example, the front bevel guide 604 may include a front guide plate 623, which includes a first front arcuate slot 629 and a second front arcuate slot 641. The first front arcuate slot 629 may have a first front radius of curvature 633 extending from a first front origin 637. Additionally, the second front arcuate slot 641 may have a second front radius of curvature 645 extending from a second front origin 649. The second front origin 649 may be spaced apart from the first front origin 637.

[0051] Similarly, the rear bevel guide 608 may include a rear guide plate 625, which may include a first rear arcuate slot 630 and a second rear arcuate slot 642. The first rear arcuate slot 630 may have a first rear radius of curvature 634 extending from a first rear origin 638. Additionally, the second rear arcuate slot 642 may have a second rear radius of curvature 646 extending from a second rear origin 650. The second rear origin 650 may be spaced apart from the first rear origin 638.

[0052] The front bevel guide 604 and the rear bevel guide 608 can have any suitable configuration and / or relative positioning. As an example, the front guide plate 623 can have and / or define a front flat guide plate surface 624, and can define a first front arcuate slot 629 and / or a second front arcuate slot 641 therein. Similarly, the rear guide plate 625 can have and / or define a rear flat guide plate surface 626, and can define a first rear arcuate slot 630 and / or a second rear arcuate slot 642 therein. In such a configuration, the rear flat guide plate surface can face the front flat guide plate surface.

[0053] As another example, the front guide plate 623 may extend parallel to or at least substantially parallel to the rear guide plate 625. As yet another example, the first front radius of curvature 633 may be equal to or at least substantially equal to the first rear radius of curvature 634. As yet another example, the second front radius of curvature 645 may be equal to or at least substantially equal to the second rear radius of curvature 646. As yet another example, the first front origin 637 may be aligned with the first rear origin 638 along the first alignment axis 639. Alternatively or additionally, the second front origin 649 may be aligned with the second rear origin 650 along the second alignment axis 651. The second alignment axis may be parallel to or at least substantially parallel to the first alignment axis.

[0054] like Figure 1-3 The dashed lines in the middle and Figure 4-13 As shown by the solid line, the bevel guide 600 may include a bevel lock 680. When the bevel lock 680 is present, it can be configured to selectively hold the bevel guide 600 at a selected bevel angle 612 within the angular range of the bevel cutting motion. Examples of the bevel lock 680 include a cam, a cam lock, a retaining screw, a wing screw, and / or a selectively actuated friction interface.

[0055] The bevel saw 10 according to this disclosure, including the bevel guide 600, can provide significant advantages over conventional bevel saws that do not include the bevel guide 600. As an example, the bevel guide 600 (including the configuration and / or relative positioning of its first arcuate slot 628 and / or second arcuate slot 640) can maintain an accurate, precise, and reproducible bevel angle 612 throughout the entire bevel cutting motion angular range, and / or have minimal hysteresis within the bevel. This contrasts with conventional bevel saws whose structures for changing the bevel angle may be inaccurate, imprecise, and / or exhibit significant hysteresis.

[0056] As another example, the bevel guide 600 (including the configuration and / or relative positioning of its first arcuate slot 628 and / or second arcuate slot 640) can allow the bevel saw 10 to remain constant or at least substantially constant at the position where the circular saw blade 200 intersects the back-axis side 312 of the substrate 304. Examples of this position are... Figure 1-2 and Figure 13Position 620 is shown in the diagram. This can include keeping position 620 constant or at least substantially constant as the angle 612 varies throughout the angle of the bevel cutting motion. In other words, the bevel saw 10 can be configured such that when the bevel angle 612 varies throughout the angle of the bevel cutting motion, the position of the saw blade plane 202 within the plane opposite to the spindle side defined by the opposite spindle side 312 of the substrate 304 can vary by less than a threshold change and / or distance. The threshold change and / or distance includes at least 0 mm, at least 0.01 mm, at least 0.05 mm, at least 0.1 mm, at least 0.15 mm, at least 0.2 mm, up to 5 mm, up to 4 mm, up to 3 mm, up to 2 mm, up to 1 mm, up to 0.5 mm, up to 0.25 mm, up to 0.1 mm, up to 0.05 mm, and / or up to 0.01 mm. This contrasts with conventional bevel saws where the position of the saw blade plane can vary significantly with the bevel angle.

Therefore, without departing from the scope of this disclosure, reference is made herein to... Figure 16-18 Any structure, function, and / or feature disclosed in the bevel saw 10 may (but is not required in all embodiments) be included. Figure 1-15 10 beveled saws neutralized / or combined with Figure 1-15 The bevel saw 10 is used together. Similarly, without departing from the scope of this disclosure, reference is made to... Figure 1-15 Any structure, function, and / or feature disclosed in the bevel saw 10 may (but is not required in all embodiments) be included. Figure 16-18 10 beveled saws neutralized / or combined with Figure 16-18 Use it together with the angled saw 10.

[0059] The bevel guide mount 700 may include a bevel guide mount fastener 720, and in some examples may include only a single bevel guide mount fastener that operatively attaches the bevel guide to the substrate. The bevel guide mount 700 may also include a reinforcement structure 732 defining an opening 736. When the bevel guide is operatively attached to the substrate via the bevel guide mount, the bevel guide mount fastener 720 may extend through the opening 736. In this configuration, the bevel guide may be described as being compressed between the reinforcement structure and the substrate.

[0060] The beveled guide mount fastener 720 may include a beveled guide mount fastener head 724, which defines a fastener head lateral cross-sectional area. The contact area between the reinforcement structure 732 and the beveled guide 600 may be at least a threshold multiple of the fastener head lateral cross-sectional area. This configuration may increase the compressive force that can be applied to the beveled guide 600 by the beveled guide mount fastener 720 without damaging the beveled guide. Additionally or alternatively, this configuration may increase the holding force applied to the beveled guide 600 by the beveled guide mount 700 and / or may reduce the likelihood of the beveled guide mount fastener loosening. Examples of threshold multiples include at least 4 times, at least 6 times, at least 8 times, at least 10 times, at least 15 times, up to 30 times, up to 20 times, up to 15 times, and / or up to 10 times the threshold multiple of the fastener head lateral cross-sectional area.

[0061] like Figure 18 As may be optimally shown, the reinforcement structure 732 may extend on the opposite side of the beveled guide mount fastener 720, such that the reinforcement structure and the beveled guide 600 define at least two spaced-apart contact areas 738. An opening 736 of the reinforcement structure 732 may extend through a central region or midpoint of the reinforcement structure 732, and the contact areas 738 may extend equal or at least substantially equal distances away from the opening 736 and / or away from the beveled guide mount fastener 720. Also as in Figure 18 As shown, the reinforcement structure 732 may not contact the bevel guide 600 in the region 740 directly below the bevel guide mount fastener head 724. This configuration allows the bevel guide mount 700 to resist torsion and / or rotation between the bevel guide 600 and the substrate 304, such as torsion and / or rotation about the elongated axis of the bevel guide mount fastener.

[0062] In some examples, substrate 304 and / or reinforcing structure 732 may have and / or define a high surface area region 744 for contact bevel guides. The presence of the high surface area region 744 can reduce the likelihood of relative movement between the bevel guide 600 and substrate 304 when the bevel guide mount 700 operably attaches the bevel guide 600 to the substrate. Examples of the high surface area region 744 include ribbed regions, serrated regions, roughened regions, and / or multiple protrusions.

[0063] As used herein, the term “and / or” placed between the first entity and the second entity means (1) the first entity, (2) the second entity, and (3) one of the first entity and the second entity. Multiple entities listed using “and / or” should be interpreted in the same way, i.e., “one or more” of the entities thus combined. In addition to the entities specifically identified by the clause “and / or”, other entities may optionally exist, whether related to or not related to those specifically identified. Thus, as a non-limiting example, when used in conjunction with open-ended language such as “including,” a reference to “A and / or B” may in one embodiment refer only to A (optionally including entities other than B); in another embodiment, only to B (optionally including entities other than A); and in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, etc.

[0064] As used herein, the phrase “at least one” in the enumeration of one or more entities should be understood to mean at least one entity selected from any one or more entities in the entity enumeration, but is not necessarily required to include at least one of every entity specifically enumerated in the entity enumeration, or excludes any combination of entities in the entity enumeration. This definition also allows for the optional presence of entities other than those specifically identified in the entity enumeration referred to by the phrase “at least one,” whether related to or unrelated to those specifically identified entities. 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”) in one embodiment may refer to at least one A, optionally including more than one A, while B is absent (and optionally including entities other than B); in another embodiment, it refers to at least one B, optionally including more than one B, while A is absent (and optionally including entities other than A); and in yet another embodiment, it refers to at least one A, optionally including more than one A, and at least one B, optionally including more than one B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and / or” are open-ended expressions that are both connected and separate in operation. For example, the expressions “at least one of A, B, and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C,” and “A, B, and / or C” can mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B, and C together, and any of the above that may optionally be combined with at least one other entity.

[0065] Where any patent, patent application or other reference is incorporated herein by reference and (1) defines a term in a manner inconsistent with the unincorporated portion of this disclosure or any other incorporated reference and / or (2) otherwise defines a term in a manner inconsistent with the unincorporated portion of this disclosure or any other incorporated reference, the unincorporated portion of this disclosure shall prevail, and the term or incorporated disclosure therein shall prevail only with respect to the reference that defines the term and / or the originally existing incorporated disclosure.

[0066] As used herein, the terms “suitable” and “configured” mean that an element, component, or other subject matter is designed and / or intended to perform a given function. Therefore, the use of the terms “suitable” and “configured” should not be construed as meaning that a given element, component, or other subject matter is merely “capable” of performing a given function, but rather that the element, component, and / or other subject matter is specifically selected, created, implemented, utilized, programmed, and / or designed for performing that function. Also within the scope of this disclosure, elements, components, and / or other described subject matter that are described as suitable for performing a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa.

[0067] As used herein, the phrases “for example,” “as an example,” and / or simply the term “example,” when used with reference to one or more components, features, details, structures, embodiments, and / or methods according to this disclosure, are intended to convey illustrative, non-exclusive examples of the components, features, details, structures, embodiments, and / or methods according to this disclosure. Therefore, the described components, features, details, structures, embodiments, and / or methods are not intended to be limiting, essential, or exclusive / exhaustive; and other components, features, details, structures, embodiments, and / or methods, including those structurally and / or functionally similar and / or equivalent, are also within the scope of this disclosure.

[0068] As used herein, when modifying degree or relation, "at least substantially" can include not only the "substantial" degree or relation, but also the full extent of the degree or relation. A substantial degree or relation can include at least 75% of the degree or relation. For example, an object at least substantially formed of material includes an object in which at least 75% of the object is formed of material, and also includes an object entirely formed of material. As another example, a first length at least substantially as long as the second length includes a first length within 75% of the second length, and also includes a first length as long as the second length.
