Each example is provided by way of illustration and/or explanation, and not as a limitation. For instance, features illustrated or described as part of one embodiment may be used on another embodiment to yield a further embodiment. Upon reading and comprehending the present disclosure, one of ordinary skill in the art will readily conceive many equivalents, extensions, and alternatives to the specific, disclosed luminaire types, all of which are within the scope of embodiments herein. [0018] In the following description, positional terms like “above,” “below,” “vertical,” “horizontal,” “bottom,” “top,” and the like are sometimes used to aid in explaining and specifying features illustrated in the drawings as presented, that is, in the oreintation which labels of the drawings read normally. [0019] FIGS.1-3 illustrate a training device 100 that may be used for cognitive training, according to various embodiments described herein. In the illustrated embodiment, the training device 100 may include a hub 110 and a plurality of arms (e.g., four arms 101, 102, 103, and 104) that may be movably coupled to and extend from the hub 110. In the illustrated embodiment, four arms 101- 104 are attached to the hub 110; however, this is merely exemplary and fewer or more arms may be provided. [0020] In some embodiments, the hub 110 may be formed of foam, but it is also envisioned that the hub 110 be formed of other lightweight materials (e.g., polymeric materials) regularly used for the construction and manufacture of sporting goods or exercise equipment. [0021] The hub 110 includes an upper side 113 (above where the arms 101-104 connect to the hub 110) and a lower side 115 (below where the arms 101-104 connect to the hub 110). In some embodiments, the hub 110 may assume a generally or entirely spherical shape. In other embodiments, the hub 110 is only partially spherical and includes a lower surface 111 (see FIG. 3) on the lower side 113 of the hub 110 that is substantially flat. However, the hub 110 may be of any shape (oval, square, triangular, etc.) and varying the geometry of either or both the hub 110 and the lower surface 111 are within the scope of this disclosure. For example, in some embodiments, the hub 110 has an oval, square, triangular, etc. shape and the lower surface 111 may not be flat but instead may be concave or convex. PATENT 105755-1401089 [0022] With reference to FIGS.5A-5B, the hub 110 may be configured to house elastic cords 121, 122 that movably couple the arms 101-104 to the hub 110. As shown in FIG.5B, each elastic cord 121, 122 may be coupled to two of the arms 101-104. For example, elastic cord 121 extends between arm 102 and arm 104, and elastic cord 122 extends between arm 101 and arm 103. Additionally, the hub 110 may include ports 131-134, through which the elastic cords 121 and 122 can extend outwardly from the hub 110 and couple to the arms 101-104. As shown, the ports 131- 134 may be aligned with each of the arms such that the elastic cords 121, 122 may extend through the hub 110 colinearly with the arms. In more detail, ports 131 and 134 may be aligned so that elastic cord 121 may pass therethrough and similarly ports 132 and 133 are aligned so that elastic cord 122 may pass therethrough. In some embodiments, the ports 131-134 may be shaped as slots, grooves, or indentions that permit movement of the cords 121, 122 in a direction toward the lower side 115 of the hub 110, while restricting movement of the cords 121, 122 in a direction toward the upper side 113 of the hub 110 and/or laterally. In this way, the ports 131-134 may be configured to limit the extent to which the arms 101-104 can spring back upwardly toward the upper side 113 when released by the user. In some embodiments, the ports 131-134 are in the shape of a slot having a closed end 135 more proximate the upper side 113 of the hub 110 and an open end 137 more proximate the lower side 115 of the hub 110. [0023] In some embodiments, the training device 100 may further include an insert 140 positioned within the hub 110. The insert 140 may include a series of internal channels 150 configured to receive a portion of the elastic cords 121 and 122. In some embodiments, the insert 140 is insert molded into the hub 110. However, the insert 140 may be formed integrally with the hub (resulting in the hub 110 and the insert 140 forming a unitary body) or may be formed separately and subsequently attached to the hub 110. [0024] In some embodiments, each channel 150 is associated with a singular elastic cord 121, 122 such that the elastic cord 121 rests within a first channel on the insert 140 and the elastic cord 122 rests within a second channel on the insert 140. Additionally, in some embodiments, each channel may extend colinearly and/or parallel with the axes of the arms 101-104 with which it is associated. For example, a first channel on the insert 140 may extend colinearly and/or parallel with the axes of the first arm 101 and the third arm 103, while a second channel on the insert 140 may extend colinearly and/or parallel with the axes of the second arm 102 and the fourth arm 104. PATENT 105755-1401089 [0025] In some embodiments, at least one plug 146 may be provided on or within the hub 110 to receive the elastic cords 121, 122 that extend through the ports 131-134. Referring to FIG. 5A, each plug 146 may take the form of a tube (e.g., plastic tube) that imparts support and rigidity to each elastic cord 121, 122. In some embodiments, an individual plug 146 is positioned at each of the ports 131-134. In other embodiments, a plug 146 may extend entirely through the hub 110 to connect opposing ports 131-134. [0026] The arms 101-104 may be formed of any relatively lightweight material and in some embodiments the arms 101-104 are formed of a foam material. However, other lightweight materials are contemplated. The arms 101-104 can be provided with features to distinguish and enhance the visibility of the arms 101-104 as well as enhance the user’s ability to grip the arms. For example, the arms 101-104 may be formed of colored materials or color may be imparted to the arms 101-104 after formation. In some embodiments, each arm 101-104 is of a color different from some or all of the other arms 101-104. The surface of the arms 101-104 may be textured for improved gripping, decorative purposes, or visual identification. [0027] In some embodiments, and with reference to FIG. 5B, each of the arms 101-104 may include a handle 141 (e.g., formed of a lightweight material such as foam) and an outer sleeve 142 positioned over each handle 141. In some embodiments, the outer sleeve 142 is formed of silicone, but such is not a requirement. Each outer sleeve 142 may be a different color from all or other of the sleeves 142 such that a user may easily differentiate between each arm 101-104. For example, each outer sleeve 142 may be of a different color (e.g., red, green, yellow, and blue). Color may be imparted to the outer sleeves 142 during or after sleeve formation. Additionally, and/or alternatively, each outer sleeve 142 may be textured for improved gripping (e.g., see FIGS. 7A- 7B), decorative purposes, or additional visual identification. In some embodiments, the outer sleeves 142 may be individually removable from each of the handles 141 so they may be cleaned and/or replaced. Each outer sleeve 142 may be designed or configured to match a desired game or activity specification and may be specifically and easily interchanged as to use the same training device 100 in a variety of different ways to enhance athletic performance. [0028] In some embodiments, anchors 144 are used to operably couple the elastic cords 121, 122 to their respective arms 101-104. Each anchor 144 may include a hollow channel configured to receive an end portion of an elastic cord 121, 122. To secure each elastic cord 121, 122 within each anchor 144, a pin 148 may be inserted through a wall of the anchor 144 to engage, secure, or PATENT 105755-1401089 pin the elastic cord 121, 122 to the anchor 144. In this way, the elastic cord 121, 122 may be retained in a tensioned state. [0029] As shown in FIG.6, each anchor 144 may be inserted within a hollow cavity of a respective arm 101-104 to secure the anchor 144 and the arm 101-104 together and thereby operably couple the arms 101-104 to the hub 110. In some embodiments, retention structures 153 may be provided on the outer surface of the anchors 144 to facilitate coupling of the anchors 144 and the arms 101- 104. For example, the outer surfaces of the anchors 144 may be threaded, patterned, or textured to help position and/or retain the components together. In some embodiments, the retention structures 153 of the anchor 144 may be sized to press-fit within an arm 101-104. Alternatively, the anchors 144 may be secured to the arms 101-104 using threading, molding, or other methods known in the art. When coupled, each arm 101-104 has a proximal end 149 positioned proximate the hub 110 and a distal end 151 distal the hub 110. Each arm 101-104 extends laterally outwardly from the hub 110 in a different direction. [0030] With the arms 101-104 installed on the anchors 144, the elastic cords 121, 122 are operably coupled to the arms 101-104 to facilitate movement of the arms 101-104 relative to the hub 110. Thus, an anchor 144 establishes a connection between an elastic cord 121, 122 and a respective arm 101-104, such that the arm 101-104 may move relative to the hub 110 while still being coupled to the hub 110. Because the elastic cords 121, 122 are under tension, each arm 101-104 is biased towards the hub 110 which helps retain each arm 101-104 in, as well as return each arm 101-104 to, an equilibrium open state. [0031] In the illustrated embodiments herein, the arms 101-104 of the training device 100 are coupled using the elastic cords 121, 122, however the present disclosure is not limited to such a connection. In an alternative example and in some embodiments, the arms 101-104 may be coupled to the hub 110 via flexible arm connectors integrally formed with the hub 110. For example, the flexible arm connectors may take the form of a cord or cords which are integrated into the hub 110, and subsequently are coupled to each of the arms 101-104. In such cases, the cord may be made of a pliable, elastic, or semi-elastic material such as foam, rubber, and/or plastic, allowing for each of the arms 101-104 to be biased towards the hub 110 without the use of an elastic cord 121, 122. In some additional embodiments, the flexible arm connection may take the form of projections which are integrally formed and extend outwards from the hub 110. Such projections would have a smaller diameter than each arm 101-104 and may be press-fit or form fit to secure PATENT 105755-1401089 each arm 101-104 to the hub 110. Said projections may be made of pliable, elastic, or semi-elastic material as to bias each of the arms 101-104 to the hub 110, encouraging the training device 100 to return to the open state. [0032] FIGS.8A-8G depict an exemplary process for manufacturing the training device 100. FIG. 8A depicts a hub 110 which may include a molded foam ball including four ports 131-134 for which elastic cords 121, 122 may be ran through. A singular arm (e.g., 101) is coupled to the hub 110 using an anchor 144 (not shown) to which an elastic cord (e.g., 122) is secured. Opposing the singular arm 101 is an unattached anchor 144. Now referring to FIG.8B, the elastic cord 122 may be pulled taught or under tension through said unattached anchor 144. As noted previously, a singular elastic cord, in this case cord 122, may be used to coupled two opposing arms (e.g., 101 and 103) to the hub. Once the elastic cord 122 is properly tensioned, and now referring to FIG.8C, the pin 148 may be inserted through an outer wall of the anchor 144, pinching or piercing the elastic cord 122, and securing the anchor 144 and the elastic cord 122 together to retain the elastic cord 122 in a tensioned state. The tension present in the singular elastic cord 122 biases both the arm 101 and the anchor 144 towards the hub 110. As depicted in FIG.8D, the excess elastic cord 122 may then be trimmed or cut, to reduce the amount of un-tensioned cord 122. [0033] In reference to FIG. 8E, with the anchor 144 secured to the elastic cord 122, a mold 160 may be positioned over the anchor 144. Such a mold 160 may be used to form the second arm 103 using, for example, over-molding, compression molding, injection molding, blow molding, or other molding techniques known in the art. In particular, the mold 160 may be used to form the handle 141 out of foam or other materials typically used in sporting good or exercise equipment. Alternatively, each arm 101-104 may be pre-formed and subsequently mounted on the anchor 144. [0034] Once the handle 141 is molded, and now referring to FIG.8F, an outer sleeve 142 may be positioned onto the handle 141. As noted previously, the outer sleeve 142 may include various colors, textures, or other identifying or aesthetic details that may be tailored to a specific use of the of the training device 100. To finish the remaining arms 102, 104, the process described in relation to FIGS.8A-8F may be repeated. For example, a third arm is depicted in FIG.8G. [0035] The manufacturing process of the training device 100 described herein and in FIGS. 8A- 8G is merely exemplary and is not intended to be limiting. Various alternative manufacturing methods, including the addition or subtraction of steps, or the reordering of various steps are envisioned within the scope of this disclosure and would be appreciate by one skilled in the art. PATENT 105755-1401089 [0036] The arms 101-104 can assume an open state and a closed state. In the open (equilibrium) state and as illustrated in FIG. 1, the arms 101-104 may extend outwardly from the hub 110 in different directions. In some embodiments, each arm 101-104 may be positioned colinearly with the respective ports 131-134 on the hub 110 from which the elastic cords 121, 122 extend. As depicted in FIG.1, arm 101 and arm 103 extend colinearly along a first axis A1 (although laterally outwardly in different directions from the hub 110), and arm 102 and arm 104 extend colinearly along a second axis A2 (although laterally outwardly in different directions from the hub 110). In the illustrated example, the first axis A1 is perpendicular to the second axis A2, allowing the training device 100 to form an approximately cross shape in the open state. It can be understood that arms extended along two axes A1 and A2 is only exemplar. In some embodiments, each of the four arms may extend along different axes or be non-linear with respect to each other. Moreover, while the arms 101-104 are shown extending substantially coplanar in the open state, such is not a requirement. [0037] In the closed state and as illustrated in FIG. 4, each of the arms 101-104 may be bent generally downwardly under tension toward the lower side 115 of the hub 110 such that they collapse against each other and their proximal ends 149 are positioned adjacent to the lower surface 111 of the hub 110. In some embodiments, the arms 101-104 may extend substantially parallel to each other when in the closed state. When in the closed state, all four arms 101-104 of the training device 100 may be gripped in a single hand of a user such that all four arms 101-104 are squeezed together, causing the elastic cords 121 and 122 to be under tension. It is envisioned that a user may be able to throw the training device 100 when in the closed state using only a single hand. Because the arms are under tension, when released each arm 101-104 springs in a direction toward the upper side 113 of the hub 110 to return to its equilibrium state. In some embodiments, their upward movement is limited by ports 131-134. Furthermore, each of the arms 101-104 may be tensioned or closed independently from one another, such that a user may selectively hold each individual arm 101-104 in either the closed state or the open state simultaneously. In some embodiments, the arms 101-104 are angled relative to the hub 110. For example, the arms 101-104 may be angled or biased in a direction toward the lower side 115 of the hub 110 to facilitate easily drawing of the arms 101-104 close to each other to assume the closed state. [0038] In one exemplary use, the described training device 100 may be used for cognitive or reaction-based training. For example, a first user may hold the device 100 in a closed state. The PATENT 105755-1401089 first user may then toss the device 100 towards a second user and, while the device 100 is airborne, the first user may call out a color associated with one of the arms 101-104. Once released by the first user, the device 100 may transition from the closed state to the open state due to the tension of the elastic cords 121, 122. The second user will then be challenged to catch the device 100 by the arm 101-104 that is associated with the color that the first user calls out. Such a task will challenge the second user’s reaction time, hand-eye coordination, and overall dexterity. Once caught, the second user may repeat the process and throw the device 100 back towards the first user, allowing for both users to improve their cognitive and reaction-based skills. This use is merely one exemplary use and other uses of the device 100 are appreciated within the scope of this disclosure. For example, a singular user may toss the device 100 in the air and catch the device 100 themselves to test and train their cognitive and reaction-based skills without the need for a second user. Similarly, the device 100 may be used by a group of users. Additionally, and as noted previously, the arms 101-104 may be configured to include various textures, colors, and other aesthetic properties, to allow for the device 100 to be interchangeably used in different applications or uses other than those described herein. [0039] The various aspects, embodiments, implementations, or features of the described embodiments can be used separately or in any combination. In particular, it should be appreciated that the various elements of concepts from FIGS.1 – 8G may be combined without departing from the spirit or scope of the invention. [0040] A collection of exemplary embodiments, including at least some explicitly enumerated as “Examples” providing additional description of a variety of example types in accordance with the concepts described herein are provided below.

[0061] The use of the terms “a” and “an” and “the” and similar referents in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The terms “comprising,” “having,” “including,” and “containing” are to be construed as PATENT 105755-1401089 open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, or gradients thereof, unless otherwise indicated herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention. [0062] As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or results. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have the same overall results as if absolute and total completion were obtained. [0063] Preferred embodiments of this invention are described herein, including the best mode known to the inventors for carrying out the invention. The invention is susceptible to various modifications and alternative constructions, and certain shown exemplary embodiments there are shown in the drawings and have been described above in detail. Variations of those preferred embodiments, within the spirit of the present invention, may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect skilled artisans to employ such variations as appropriate, and the inventors intend for the invention to be practiced otherwise than as specifically described herein. Accordingly, it should be understood that there is no intention to limit the invention to the specific form or forms disclosed, but on the contrary, this invention includes all modifications and equivalents of the subject matter recited in the claim appended hereto as permitted by applicable law. Moreover, any combination of the above- described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context. The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the described embodiments. However, it will be apparent to one skilled in the art that the specific PATENT 105755-1401089 details are not required in order to practice the described embodiments. Thus, the foregoing descriptions of specific embodiments are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the described embodiments to the precise forms disclosed. It will be apparent to one of ordinary skill in the art that many modifications and variations are possible in view of the above teachings. [0064] It is to be understood that terms such as “distal,” “proximal,” “side,” “inner,” and the like that can be used herein merely describe points of reference and do not necessarily limit embodiments of the present disclosure to any particular orientation or configuration. As used herein, “proximal” refers to a direction toward the end of the female contact stack near the clinician and “distal” refers to a direction away from the clinician and (generally) inside the body of a patient. Furthermore, terms such as “first,” “second,” “third,” etc., merely identify one of a number of portions, components, steps, operations, functions, and/or points of reference as disclosed herein, and likewise do not necessarily limit embodiments of the present disclosure to any particular configuration or orientation. [0065] The terms “longitudinal,” “axial” or “axially” are generally longitudinal as used herein to describe the relative position related to a female contact stack or other components of the system herein. For example, “longitudinal” or “axial” indicates an axis passing along a center of a female contact stack from a proximal end to a distal end. The term “radial” generally refers to a direction perpendicular to the “axial” direction. [0066] Disjunctive language such as the phrase “at least one of X, Y, or Z,” unless specifically stated otherwise, is intended to be understood within the context as used in general to present that an item, term, etc., may be either X, Y, or Z, or any combination thereof (e.g., X, Y, and/or Z). Thus, such disjunctive language is not generally intended to, and should not, imply that certain embodiments require at least one of X, at least one of Y, or at least one of Z to each be present. [0067] While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the present disclosures. Indeed, the novel methods, apparatuses and systems described herein can be embodied in a variety of other forms; furthermore, various omissions, substitutions and changes in the form of the methods, apparatuses and systems described herein can be made without departing from the spirit of the present disclosures.
