Exercise is a beneficial activity that may improve physical health and mental health, among others. Exercising with weights may provide further improvements. In some circumstances, acquiring a variety of weights to be used in various exercises may be costly and may require large amounts of space to maintain the various weights.

A smart weight system may provide one or more devices that may include configurable weights such that the smart weight system may be used for many different exercises, regardless of the weight a user may desire for the exercise.

In some circumstances, a smart weight system may improve the user’s exercise experience and may contribute to safer conditions while exercising. For example, the smart weight system may assist in selecting a proper weight for use in an exercise based on the user’s abilities, the balancing of the weight, improving the user’s form while exercising with regard to the weight, etc. Further, the smart weight system may contribute to reducing the amount of space that may be used to house exercise equipment by providing a reconfigurable weight in a uniform form factor.

These and other embodiments of the present disclosure will be explained with reference to the accompanying figures. It is to be understood that the figures are diagrammatic and schematic representations of such example embodiments, and are not limiting, nor are they necessarily drawn to scale. In the figures, features with like numbers indicate like structure and function unless described otherwise.

FIGS. 1A and IB illustrate two embodiments of an example smart weight system 100, in accordance with at least embodiment described in the present disclosure. FIG. 1A illustrates a perspective view of a kettlebell smart weight system 100a and FIG. IB illustrates a perspective view of a dumbbell smart weight system 100b. The kettlebell smart weight system 100a and the dumbbell smart weight system 100b may be referred to generically as the smart weight system 100. The smart weight system 100 may include an adjustable device 105 (e.g., a weight) and a dock 110. For example, the kettlebell smart weight system 100a may include a kettlebell device 105a and a kettlebell dock 110a. The dumbbell smart weight system 100b may include a first dumbbell device 105b, a second dumbbell device 105c, and a dumbbell dock 110b. The dumbbell smart weight system 100b is illustrated in FIG. IB as including two dumbbell devices 105b-c and a single dumbbell dock 110b for exemplary purposes. The dumbbell smart weight system 100b may include one or more dumbbell devices 105b-c, dumbbell docks 110b, or some combination thereof. For example, the dumbbell smart weight system 100b may include one dumbbell devices 105b and one dumbbell dock 110b. The kettlebell device 105a and the dumbbell device 105b may be referred to generically as the device 105 and the kettlebell dock 110a and the dumbbell dock 110b may be referred to generically as the dock 110.

In some embodiments, the kettlebell device 105a may include a weight body 115a. For example, the kettlebell device 105a may include a spherically shaped weight body 115a, which shape may be the same or similar to a traditional kettlebell. Each of the dumbbell devices 105b-c may include a cylindrically shaped first weight body 115-lb that may be joined to a cylindrically shaped second weight body 115-2b (referred to collectively as the weight bodies 115b) with a handle 120b affixed therebetween, which configuration may be the same or similar to a traditional dumbbell. The weight bodies 115a-b are referred to collectively as weight bodies 115. In some embodiments, the weight bodies 115 may be symmetric across a bisector of the device 105. For example, similar to a traditional kettlebell, the kettlebell device 105a may be symmetric across a vertical midline, and similar to a traditional dumbbell, the dumbbell device 105b may be symmetric across a vertical midline as illustrated and discussed in more detail in relation to FIGS. 2A-4B.

In some embodiments, the weight bodies 115 may include hardened, heavy, and/or dense materials. For example, the weight bodies 115 may include metal, polymers (such as plastic), composites, and/or other suitable materials. In some embodiments, the weight bodies 115 may include a surface coating material that may contribute to impact resistance of the weight bodies 115, and/or reduced likelihood of damage from drops to the weight bodies 115 or an object the weight bodies 115 contact, and/or visual aesthetics. For example, the weight bodies 115 may be covered with a polymer, elastomer, rubber, rubber- like materials, and/or other suitable materials.

In some embodiments, the device 105 may be configured to be received in and/or interface with the dock 110. In some embodiments, the dock 110 may be size and shaped to receive the device 105 associated with the dock 110. For example, the kettlebell dock 110a may be sized and shaped to receive the kettlebell device 105a and the dumbbell dock 110b may be sized and shaped to receive the dumbbell device 105b.

Further details related to the smart weight system 100, including the device 105, the dock 110, additional elements included therein, and/or the interaction between the device 105, the dock 110, and the additional elements, may be described relative to and in conjunction with the subsequent figures. It will be appreciated that a barbell may also be included as a device 105 in the smart weight system 100. For example, a barbell may be analogous to the dumbbell device 105b, in that the barbell may include an elongated handle with weights affixed to the ends thereof. In some embodiments, the handle of the barbell may be longer than the handle of the dumbbell device 105b. Alternatively or additionally, the size of the weight bodies 115 affixed to the ends of a barbell handle may be larger than the size of the weight bodies 115 of the dumbbell device 105b. For example, the weight bodies 115 associated with a barbell device may be substantially the same shape as the weight bodies 115b. The weight bodies 115 associated with and the barbell device may be scaled to be larger than the weight bodies 115b such that a greater weight may be accommodated by the barbell via the weight bodies 115 associated with the barbell device.

In some embodiments, the smart weight system 100 may include a barbell dock associated with the barbell device. In some embodiments, the barbell dock may be analogous in shape to the dumbbell dock 110b. For example, the barbell dock may be substantially thin and/or flat and may be sized and shaped to receive a barbell device. In some embodiments, the barbell dock may include a unitary device, similar to the dumbbell dock 110b where the receptacles on the dock 110 that are configured to interface with the weight bodies 115 are attached to a base portion in a uniform device. Alternatively or additionally, the dock 110 associated with a barbell device may include two separate dock members, where each dock member may be configured to interface with one weight body of the weight bodies 115 associated with the barbell device.

In some embodiments, the barbell dock may be configured to include a taller stand portion than the dumbbell dock. For example, the barbell dock may be sized such that the barbell dock may be used in conjunction with a weightlifting bench. The height of the barbell dock may be sized such that the barbell dock may hold the barbell device above the weightlifting bench which may allow a user to position themselves on the weightlifting bench and use the barbell device. Alternatively or additionally, the barbell dock may include one or more mechanisms that may allow the height of the barbell dock to vary. For example, the barbell dock may include hydraulic, electronic, and/or mechanical mechanisms that may be configured to adjust the height of the barbell dock such that the barbell device may be easier to handle in different circumstances (e.g., such as a short height position for a deadlift, a medium height position for a bench press, and a tall height position for a squat). The device may include an electronic motion capture unit 135. For example, the kettlebell device 105a may include an electronic motion capture unit 135a and the dumbbell device 105b may include electronic motion capture units 135b-c, generally referred to as electronic motion capture unit 135. The electronic motion capture unit 135 may be configured to capture usage data related to a user’s use of the device 105. For example, the electronic motion capture unit 135 may be configured to monitor a speed in which a repetition of the device 105 is performed, an orientation of the device 105 during use, equal distribution of weight between the weight bodies 115, etc.

In some embodiments, the electronic motion capture unit 135 may include one or more inertial measurement units (IMUs). The IMUs may be configured to capture motion in six axes. Alternatively or additionally, the IMUs may be configured to capture motion in nine axes.

Alternatively or additionally, the handle 120 may include a hollow portion between the two attachment points of the handle 120.

In some embodiments, the hollow portion of the handle 120 may span the length of the handle 120. For example, the handle 120 may be hollow between the two attachment points of the handle 120 to the weight bodies 115. Alternatively or additionally, the hollow portion of the handle 120 may extend through a portion of the handle 120, such that the hollow portion may be sized to house an electronic motion capture unit 135a-c.

FIGS. 6A and 6B illustrate exploded perspective views of the kettlebell smart weight system 100a and the dumbbell smart weight system 100b, respectively, in accordance with at least one embodiment described in the present disclosure. The dumbbell smart weight system 100b is illustrated in FIG. 6B as including a single dumbbell device 105b for ease of illustration. FIGS. 6A and 6B illustrate one or more concentric weights 125a-b, referred to generally as concentric weights 125, that may be used in conjunction with the smart weight system 100. The kettlebell smart weight system 100a may include concentric weights 125a and the dumbbell smart weight system 100b may include concentric weights 125b. The concentric weights 125 may selectively attach to the weight bodies 115. The dumbbell smart weight system 100b is illustrated in FIG. 6B as including a single set of concentric weights 125 a for ease of illustration. The dumbbell smart weight system 100b may include two or more sets of concentric weights 125a corresponding to the number of weight bodies 115b. For example, the dumbbell smart weight system 100b may include four sets of concentric weights 125 and four weight bodies 115b.

In some embodiments, the concentric weights 125 may include multiple concentric weight plates 127a-b, referred to generally as weight plates 127, that may be used to adjust an overall weight of the device 105. In some embodiments, each weight of the weight plates 127 may vary in weight relative to another weight plate 127. For example, the innermost weight plate 127 of the concentric weights 125 may be lighter than the next adjacent weight plate 127 of the concentric weights 125, and so forth. Alternatively or additionally, each weight of the weight plates 127 may be the same or nearly the same weight as the other weight plates 127 of the concentric weights 125.

In some embodiments, the concentric weights 125 may include one or more locking pins (not illustrated) disposed thereon. In some embodiments, the locking pins may be located on a medial surface of the concentric weights 125. For example, the locking pins may be disposed on the concentric weights 125 on a side opposite to the side of the concentric weights 125 that point out and are visible to the user.

In some embodiments, the locking pins may be used in conjunction with a locking mechanism, such as the weight lock mechanism 140 as described in relation to FIGS. 8A and 8B, to secure (e.g., selectively attach) the concentric weights 125 inside the device 105. Alternatively or additionally, the locking pins may be used to guide the concentric weights 125 in position inside the device 105. For example, the locking mechanism inside the device 105 may include one or more receptacles that may be sized and shaped to receive the locking pins such that when the locking pins are received within the receptacles, the associated weight plate(s) 127 may be properly located within the device 105 and selectively attached to the weight body 115.

In some embodiments, the concentric weights 125 may be substantially round to fit within a casing portion of the device 105. Alternatively or additionally, the concentric weights 125 may include one or more notches that may provide a user with a better grip of the concentric weights 125. In some embodiments, the concentric weights 125 may be sized and shaped such that the concentric weights 125 may be interchangeable between various smart weight systems 100. For example, the concentric weights 125a of the kettlebell smart weight system 100a may be interchangeable with the concentric weights 125b of the dumbbell smart weight system 100b or with the concentric weights of another kettlebell smart weight system 100a. Alternatively or additionally, the concentric weights 125 may be sized and shaped (which may include unique locking pins) such that the concentric weights 125 may be limited in use to the smart weight system 100 associated with the concentric weights 125. For example, the concentric weights 125a of the kettlebell smart weight system 100a may be limited in use to the kettlebell smart weight system 100a. As another example, the concentric weights 125b of the dumbbell smart weight system 100b may be limited in use to the dumbbell smart weight system 100b.

In some embodiments, the concentric weights 125 may be removable from the device 105 in instances in which the device 105 is located on the dock 110. Alternatively or additionally, the concentric weights 125 may be locked in place in instances in which the device 105 is remote (e.g., removed) from the dock 110.

In some embodiments, the concentric weights 125 may include hardened, heavy, and/or dense materials. For example, the concentric weights 125 may include metal, polymers (such as plastic), composites, and/or other suitable materials. In some embodiments, the concentric weights 125 may include a surface coating material that may contribute to better handling of the concentric weights 125, reduced likelihood of damage from drops to the concentric weights 125 or an object the concentric weights 125 contacts, and/or visual aesthetics. For example, the concentric weights 125 may be covered with a polymer, elastomer, and/or other suitable materials.

FIGS. 7A and 7B illustrate perspective views of the kettlebell smart weight system 100a and the dumbbell smart weight system 100b, respectively, in accordance with at least one embodiment described in the present disclosure. The dumbbell smart weight system 100b is illustrated in FIG. 7B as including a single dumbbell device 105b for ease of illustration. FIGS. 7A and 7B illustrate a cavity 130a-b of the smart weight system 100. The weight bodies 115 may define the cavities 130a-b, referred to generally as cavity 130. For example, the weights body 115a of the kettlebell smart weight system 100a may define the cavity 130a. As another example, the weight bodies 115b of the dumbbell smart weight system 100b may define the cavity 130b. The cavity 130 may be used to house at least the concentric weights 125 in conjunction with the smart weight system 100.

The weight bodies 115 may include a casing in which an outer surface of the casing defines the shape of the device 105 and an inner surface of the casing defines the shape and size of the cavity 130. In some embodiments, the cavity 130 may be sized and shaped to receive and/or retain one or more of the concentric weights 125. Alternatively or additionally, the cavity 130 may be sized and shaped to receive and/or retain a weight locking mechanism. Additional details related to the weight locking mechanism are discussed in relation to FIGS. 8A and 8B.

In some embodiments, the shape of the device 105 may remain uniform regardless of the total amount of weight of the device 105 and/or the number of the concentric weights 125 that may be included therein. For example, the kettlebell device 105a when including two attached concentric weights 125 may be the same size and/or shape as the kettlebell device 105 a when including zero attached concentric weights 125. As another example, the dumbbell device 105b when including three attached concentric weights 125 may be the same size and/or shape as the dumbbell device 105b when including one attached concentric weight 125. In some embodiments, the cavity 130 may be sized and shaped to house the electronic motion capture units 135a-c.

FIG. 8 A illustrates a perspective view of an example weight lock mechanism 140 that may be implemented in the smart weight system 100, in accordance with at least one embodiment described in the present disclosure.

In some embodiments, the weight lock mechanism 140 may be sized and shaped to be placed within the cavity 130 of the weight bodies 115. In some embodiments, the weight lock mechanism 140 may be retained (e.g., attached) within the cavity 130 using screws, dowels, and/or any other appropriate fasteners. In some embodiments, the weight lock mechanism 140 may be configured to interface with the concentric weights 125, which may include holding and/or selectively attaching the concentric weights 125 in position while in use and releasing the concentric weights 125 as desired when the device 105 is located at the dock 110.

In some embodiments, the weight lock mechanism 140 may include one or more subcomponents that may function in concert to receive and retain the concentric weights 125. Additional details related to the subcomponents of the weight lock mechanism 140 are discussed relative to FIG. 8B.

FIG. 8B illustrates an exploded perspective view of the weight lock mechanism 140 that may be implemented in the smart weight system 100, in accordance with at least one embodiment described in the present disclosure.

In some embodiments, the weight lock mechanism 140 may include a weight interface 145, which may be the front surface of the weight lock mechanism 140. The weight interface 145 may be configured to selectively attach to (e.g., interface with) the concentric weights 125. For example, the weight interface 145 may define one or more receptacles 801 configured to receive the locking pins from the concentric weights 125. In FIG. 8B, a single receptacle is denoted as 801 to illustrate an example receptacle and for ease of illustration.

Alternatively or additionally, the weight interface 145 may include a tiered surface, such as arranged in rings 803a-c, which may be associated with different sizes of weights of the concentric weights 125. For example, an outermost weight of the concentric weights 125 may be configured to contact an outer ring 803a of the weight interface 145, and so forth.

In some embodiments, the weight interface 145 may include hardened, heavy, and/or dense materials. For example, the weight interface 145 may include metal, polymers (such as plastic), composites, and/or other suitable materials. In some embodiments, the weight interface 145 may include a surface coating material. For example, the weight interface 145 may be covered with a polymer, elastomer, and/or other suitable materials.

In some embodiments, one or more locking disks 150 may be disposed adjacent to the weight interface 145, such that the weight interface 145 may be located between the locking disks 150 and the concentric weights 125 (when selectively attached to the weight interface 145). In some embodiments, the locking disks 150 may be configured to interface with the locking pins of the concentric weights 125 such that the concentric weights 125 may be restricted from separating from the weight interface 145. For example, the locking disks 150 may be configured to tighten against the locking pins of the concentric weights 125 which may hold the locking pins in place through the weight interface 145.

In some embodiments, the locking disks 150 may be configured to actuate rotationally about an axis 805 through the center of the weight lock mechanism 140. Alternatively or additionally, the locking disks 150 may be configured to actuate linearly. In these and other embodiments, the actuation of the locking disks 150 may contribute to restricting the locking pins within the weight interface 145. In some embodiments, the actuation of the locking disks 150 may be caused by one or more springs (not illustrated) creating tension in instances in which the device 105 is not located on the dock 110. In some embodiments, additional securing mechanisms may be used to contribute to securing the locking pins. For example, in instances in which the device 105 is not located on the dock 110, circlips, grub screws, and/or other fasteners may be used to contribute securing the locking pins in place.

In some embodiments, each weight of the concentric weights 125 may be associated with a locking disk of the locking disks 150. For example, the innermost concentric weight 125 may be associated with a locking disk of the locking disks 150 and the outermost concentric weight 125 may be associated with a different locking disk of the locking disks 150. Alternatively, the locking disks 150 may be configured such that one locking disk 150 may be associated with all of the concentric weights 125. For example, the locking disks 150 may include a single tiered structure such that different tiers of the locking disks 150 may be configured to associate with different locking pins of the concentric weights 125. Alternatively or additionally, the locking disks 150 may be combined with an unlocking disk 155 as described below. The unlocking disk 155 may cause the locking and unlocking of the concentric weights 125 to be performed by a single actuating unit.

In some embodiments, the locking disks 150 may include hardened, heavy, and/or dense materials. For example, the locking disks 150 may include metal, polymers (such as plastic), composites, and/or other suitable materials. In some embodiments, the locking disks 150 may include a surface coating material. For example, the locking disks 150 may be covered with a polymer, elastomer, and/or other suitable materials.

In some embodiments, the weight lock mechanism 140 may include the unlocking disk 155. The unlocking disk 155 may be arranged such that the locking disks 150 may be located between the unlocking disk 155 and the weight interface 145. In some embodiments, the unlocking disk 155 may be configured to actuate the locking disks 150.

In some embodiments, the unlocking disk 155 may include hardened, heavy, and/or dense materials. For example, the unlocking disk 155 may include metal, polymers (such as plastic), composites, and/or other suitable materials. In some embodiments, the unlocking disk 155 may include a surface coating material. For example, the unlocking disk 155 may be covered with a polymer, elastomer, and/or other suitable materials.

In some embodiments, the weight lock mechanism 140 may include a back plate 160. The back plate 160 may be arranged such that the locking disks 150, the unlocking disk 155, a bearing 165, or some combination thereof may be located between the weight interface 145 and the back plate 160. In some embodiments, the back plate 160 may be configured to be attached to the weight bodies 115. For example, the back plate 160 may include receptacles, dowels, pins, threads, or any appropriate fastening mechanisms that may be complementary to fastening mechanisms of the weight bodies 115, such that the back plate 160 may be attached to the weight bodies 115, such as within the cavity 130 thereof.

In some embodiments, the back plate 160 may include hardened, heavy, and/or dense materials. For example, the back plate 160 may include metal, polymers (such as plastic), composites, and/or other suitable materials. In some embodiments, the back plate 160 may include a surface coating material. For example, the back plate 160 may be covered with a polymer, elastomer, and/or other suitable materials.

In some embodiments, the bearing 165 may be disposed in the weight lock mechanism 140 which may contribute to the operation of the rotational or linear actuation of the components therein. In some embodiments, the bearing 165 may be located in and/or between the weight interface 145 and the back plate 160. In some embodiments, the bearing 165 may include a rotational or a linear bearing which may be associated with the actuation motion of the weight lock mechanism 140.

FIGS. 9A and 9B illustrate perspective views of the kettlebell dock 110a of the kettlebell smart weight system 100a and the dumbbell dock 110b of the dumbbell smart weight system 100b, respectively, in accordance with at least one embodiment described in the present disclosure.

In some embodiments, the dock 110 may be configured to receive and/or interface with the associated device 105. For example, the kettlebell dock 110a may be configured to receive and/or interface with the kettlebell device 105a and the dumbbell dock 110b may be configured to receive and/or interface with the dumbbell device 105b. As discussed, relative to FIGS. 5A and 5B, the dock 110 may include shaped receptacles 503a- e that may be complementary to the shape of the device 105. In some embodiments, the shape of the receptacles 503a-e may be configured to guide the device 105 into a proper resting position. The proper resting position may include the device 105 interfacing with one or more unlocking cams 170a-b, referred to generally as unlocking cams 170, disposed on the dock 110.

The unlocking cams 170 may be disposed within the receptacles 503a-e. In some embodiments, the unlocking cams 170 may be configured to interface with the unlocking disk 155, such that the unlocking disk 155 may be configured to unlock the concentric weights 125 which may allow the concentric weights 125 to be removed from the device 105 when the device 105 is docked with the dock 110. For example, the unlocking cams 170 may be configured to actuate the unlocking disk 155 rotationally or linearly, depending on the implementation of the weight lock mechanism 140, such that the springs associated with the actuation of the locking disks 150 may disengage and the concentric weights 125 may be selectively attached (e.g., added) to or selectively removed from the device 105. In these and other embodiments, the unlocking cams 170 may interface with the device 105, such as with the unlocking disk 155, in instances in which the device 105 is docked with the dock 110 (e.g., located on the dock 110). For example, the weight bodies 115 may define a receptacle on a bottom portion thereof, such that the unlocking cams 170 may interface with the unlocking disk 155 through the receptacle when the device 105 is docked on the dock 110.

In some embodiments, the dock 110 may include one or more displays 901a-b, referred to generally as display 901. For example, the dock 110 may include an LED display, a liquid crystal display (LCD), an E-ink display, an organic-LED (OLED) display, a thin film transistor (TFT)-LCD display, or any other appropriate display. In some embodiments, the display 901 may be curved. The display 901 may also display other information such as but not limited to a battery level of the dock 110 and or the electronic motion capture unit 135, communication system related information, alerts related working, firmware versions of various connected electronics, a product Sub-Category, or some combination thereof.

FIGS. 10A and 10B illustrate exploded perspective views of the kettlebell dock 110a of the kettlebell smart weight system 100a and the dumbbell dock 110b of the dumbbell smart weight system 100b, respectively, in accordance with at least one embodiment described in the present disclosure.

In some embodiments, the dock 110 may include weight sensing electronics 1001a- h, referred to generally as weight sensing electronics 1001. For example, the kettlebell dock 110a may include the weight sensing electronics lOOla-d physically positioned proximate a bottom surface of the kettlebell dock 110a. As another example, the dumbbell dock 110b may include the weight sensing electronics lOOle-h physically positioned between a bottom portion 1009 of dumbbell dock 110b and the unlocking cams 170b.

The weight sensing electronics 1001 may determine the weight of the device 105 while the device 105 is docked on the dock 110. In some embodiments, the weight sensing electronics 1001 may include force sensors, such as load cells and/or proximity sensors, to determine the weight of the device 105 docked on the dock 110. For example, the weight sensing electronics 1001 may include strain-gauge load cells, piezoelectric load cells, inductive load cells, capacitive load cells, magneto strictive load cells, and/or other load cells or force sensors. In some embodiments, the display 901 may be associated with the weight sensing electronics 1001. The display 901 may display the weight of the device 105 as determined by the weight sensing electronics 1001.

As illustrated in FIG. 10A, the kettlebell dock 110a may form a cam recess 1007a that is shaped and positioned to mate with the unlocking cam 170a. The cam recess 1007a may mate with the unlocking cam 170a to prevent the unlocking cam 170a from moving relative the kettlebell dock 110a.

As illustrated in FIG. 10B, the dumbbell dock 110b may include the bottom portion 1009, atop portion 1011, and a display housing 1003. The top portion 1011 may define a display opening 1005 and cam recesses 1007b-e. The cam recesses 1007b-e may mate with the unlocking cams 170b, the weight sensing electronics 1001, or some combination thereof. The display opening 1005 may mate with the display 901b, the display housing 1003, or some combination thereof. The top portion 1011 may mate with the bottom portion 1009 and the display housing 1003 to sandwich the display 901b between the top portion 1011 and the display housing 1003. When the dumbbell dock 110b is put together, the display 901b may be physically positioned within at least a portion of the display opening 1005. In addition, the cam recesses 1007b-e may mate with the unlocking cams 170b to prevent the unlocking cams 170b from moving relative the dumbbell dock 110b.

Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).

Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner.

Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”

Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.

All examples and conditional language recited herein are intended for pedagogical objects to aid the reader in understanding the invention and the concepts contributed by the inventor to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Although embodiments of the present disclosure have been described in detail, it should be understood that the various changes, substitutions, and alterations could be made hereto without departing from the spirit and scope of the present disclosure.
