SYSTEMS AND METHODS FOR MEASURING BOWLING BOWL DYNAMICSCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to and the benefit of U.S. Provisional Application No. 63 / 506,251, filed June 5, 2023, the entire content of which is incorporated by reference in its entirety.TECHNICAL FIELD

[0002] The present disclosure is in the field of systems and methods of measuring one or more parameters or variables of bowling ball dynamics / kinematics. More particularly, the present disclosure provides systems and methods for real time measurement and feedback regarding bowling ball travel.BACKGROUND

[0003] In every sport or physical competition there are unique variables that influence performance. Improving performance in sports that involve projectiles is a complex process and requires an understanding of the variables that the competitor can influence and the dynamics of the projectile (e.g., a bowling ball) both when it is in the competitor’s control and after it has begun its travel. Understanding the path, speed, rotation, and velocity of the projectile can be a vital means for improving performance. However, capturing and interpreting this data in a means that is useful for the competitor has proven difficult. In contrast to the more uniform weight and surface of e.g., a baseball, a bowling ball includes holes for the competitor’s fingers / thumb. These affect the weight distribution, and spin of the ball. This is further complicated by the complex interaction between the ball and the lane itself and the oil that is applied thereto. Environmental conditions such as magnetic field strength, atmospheric pressure, temperature, and humidity can also further complicate the interaction between the ball, lane, and oil. While measuring and interpreting data on the path and spin of a baseball is challenging, the unique nature of the make-up of a bowling ball is that much more complicated by the necessity of the grip holes and the unique aspects of bowling ball travel.

[0004] One other important factor makes bowling even more unique and difficult with respect to measuring and providing useful feedback. Modem competitive bowlers use several balls,each with their own unique and specific weight distribution characteristics. This allows the bowler to select and specialize their shots to the needs of the moment. However, this can also make translating known and practiced throws more complicated as the processes and habits developed on one ball may not translate to another ball in the bowler’s repertoire.SUMMARY

[0005] The following is a brief summary of subject matter that is described in greater detail herein. This summary is not intended to be limiting as to the general inventive concepts or the scope of the claims.

[0006] The general inventive concepts are based, in part, on the discovery that a sensor insert may be positioned within one or more bowling ball holes (e.g., a thumb hole) that can measure, in real time, the dynamics of a bowling ball throw and / or bowling environment conditions. These measurements provide vital feedback to the user on one or more aspects of bowling ball dynamics or bowling environment conditions which aid the user in developing skills and strategies for competition.

[0007] Disclosed herein are various technologies pertaining to wireless measurement, storage, and communication of parameters (e.g., including but not limited to velocity, acceleration, spin, spin rate, axis, tilt, release angle, geometry, angular momentum, axis of rotation, etc.) associated with the travel / flight of a bowling ball during a bowling exercise. More specifically, the general inventive concepts contemplate a customizable and interchangeable sensor (e.g., an inertial measurement unit) insert for inclusion in a bowling ball. In certain embodiments, the system includes a reusable, portable measurement device for incorporation into a bowling ball. In a specific embodiment, the insert is adapted for positioning in a hole in the bowling ball. The system calculates, measures, stores, and communicates the relevant data to a display or other means for interpretation by the user. Non-limiting measurement means include an accelerometer, gyroscope, magnetometer, pressure sensor, temperature sensor, and humidity sensor. The insert should not interfere with the intended spin and functioning of the ball, while it should be able to be removably and repeatedly inserted, removed and (re)inserted into the same or another ball without substantially interfering with the expected performance of either the ball or measuring / communication aspects of the insert.

[0009] According to an exemplary embodiment, a method for measuring bowling ball dynamics or bowling environment conditions is disclosed. The method comprises fixing a base to a bowling ball; removably coupling a sensor to an insert; removably coupling the insert to the base; recording a sensor measurement with the sensor; and outputting the sensor measurement.

[0010] According to an exemplary embodiment, a system for measuring bowling ball dynamics or bowling environment conditions is disclosed. The system comprises a base, an insert, and a sensor.

[0039] Various technologies pertaining to systems and methods for measuring bowling ball dynamics or bowling environment conditions are described in detail herein. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspect(s) may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more aspects. Further, it is to be understood that functionality that is described as being carried out by certain system components may be performed by multiple components. Similarly, for instance, a component may be configured to perform functionality that is described as being carried out by multiple components.

[0040] The term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form.

[0041] Ranges as used herein are intended to include every number and subset of numbers within that range, whether specifically disclosed or not. Further, these numerical ranges should be construed as providing support for a claim directed to any number or subset of numbers in that range. For example, a disclosure of from 1 to 10 should be construed as supporting a rangeof from 2 to 8, from 3 to 7, from 5 to 6, from 1 to 9, from 3.6 to 4.6, from 3.5 to 9.9, and so forth.

[0042] Any combination of method or process steps as used herein may be performed in any order, unless otherwise specified or clearly implied to the contrary by the context in which the referenced combination is made.

[0043] While those of ordinary skill will understand that the system of the general inventive concepts comprises the mechanical parts for measuring bowling ball dynamics or bowling environment conditions, for ease of description, in certain instances the system will be described as incorporated into a bowling ball. Further, as used herein, the term “exemplary” is intended to mean serving as an illustration or example of something and is not intended to indicate a preference.

[0044] According to an exemplary embodiment, a system for measuring bowling ball dynamics or bowling environment conditions is disclosed. The system comprises a base, an insert, and a sensor housing, wherein the base is configured to be at least partially disposed within an indentation on a surface of a bowling ball, the base comprises a wall and a protrusion extending from the wall, the base comprises a first end having an opening configured to receive the insert, the insert comprises a wall having a channel configured to receive the protrusion of the base to restrain relative movement between the insert and the base, and the sensor housing is coupled to the insert.

[0045] According to an exemplary embodiment, a method for measuring bowling ball dynamics bowling ball dynamics or bowling environment conditions is disclosed. The method comprises fixing a base to a bowling ball; removably coupling a sensor to an insert; removably coupling the insert to the base; recording a sensor measurement with the sensor; and outputting the sensor measurement.

[0046] According to an exemplary embodiment, a system for measuring bowling ball dynamics or bowling environment conditions is disclosed. The system comprises a base, an insert, and a sensor. The base is configured to be at least partially disposed within an indentation on a surface of a bowling ball. The base comprises a wall and a protrusion extending from the wall. The base comprises a first end having an opening configured to receive the insert. The insert comprises a wall having a channel configured to receive the protrusion of the base torestrain relative movement between the insert and the base and the sensor is coupled to the insert. The sensor comprises a processor and memory that stores instructions that, when executed by the processor, cause the processor to perform acts comprising recording a sensor measurement; and outputting the sensor measurement.

[0047] With reference to Fig. 1, an exemplary system 100 for measuring bowling ball dynamics or bowling environment conditions is shown. In its most general sense, the system is embodied by a reusable, portable measurement device for incorporation into a bowling ball. In Fig. 1, the system 100 is at least partially positioned / disposed within an indentation (e.g., a ball hole) 104 of a bowling ball 102. In a specific embodiment, the system is adapted for positioning in a hole (e.g., the thumb hole) in the bowling ball. In embodiments, the system may be sized to fit into an existing indentation on the ball, an existing indentation may be bored larger to fit the system, or a new indentation may be formed (e.g., drilled or bored) on the surface of the ball, where the indentation has a diameter and depth sized to receive the system (e.g., such that the system fits snugly and entirely within the indentation). The system calculates, measures, stores, and communicates relevant measured data to a display or other means for interpretation by the user. The system 100 comprises a support base 106, an insert 108, and a slug 112, comprising a slug hole 114 for accepting a user’s digit. In the embodiment shown in Fig. 1, the system is positioned within the thumb hole of the ball 102. Those of ordinary skill will understand that the general inventive concepts contemplate positioning the system within any of the accessible holes on the bowling ball, the thumb hole is shown here as it is generally the largest and thereby the best equipped to accommodate the system. As can be seen from Fig. 1, the slug 112 nests within the insert 108, which in turn, nests within the support base 106.

[0048] Fig. 2 shows an exploded view of an exemplary system 100 for measuring bowling ball dynamics or bowling environment conditions. The support base 106 (also called the “base”) comprises an opening to receive the insert 108 and an insert engagement portion 308 configured to engage the insert 108, for example, to restrain relative movement between the insert 108 and the base 106. The insert 108 comprises an opening to receive the slug 112 and a base engagement portion 508 configured to engage the base 106, for example, to restrain relative movement between the insert 108 and the base 106. The insert 108 is further configured to receive and / or couple (e.g., detachably couple) to a sensor or sensor housing 110.

[0049] The support base 106 comprises a wall and the insert engagement portion 308 may comprise at least one protrusion extending (e.g., inwardly) from the wall. The support base 106 is substantially in the form of a cylinder comprising a first end having an opening configured to receive the insert 108. While the support base 106 is roughly cylindrical, the support base 106 may be tapered, for example, such that a first diameter on an upper portion of the support base 106 is larger than a second diameter on a lower portion of the support base 106. In another embodiment, the base can have an upper section that is a substantially straight-walled cylinder and a lower section that is a tapered cylinder. Such tapered configurations can ease installation and / or enable a friction fit between the support base and ball hole. The support base 106 comprises a second end opposite the first end and the wall is disposed therebetween. The support base 106 is configured to be at least partially disposed within an indentation 104 on a surface of a bowling ball 102 (e.g., a thumb hole). At least a portion of the wall and / or second end of the base 106 is adhered to a portion of the indentation 104, for example, with glue. In the embodiment shown in the figure, the wall of the base 106 extends upwardly from a bottom of the base and the protrusion is in the form of at least one raised circle that extends inwardly from the wall of the cylindrical support base.

[0050] The insert 108 is in the form of a cylinder with a wall. While the insert 108 is roughly cylindrical, the insert may be tapered, for example, such that a first diameter on an upper portion of the insert is larger than a second diameter on a lower portion of the insert. In another embodiment, the insert can have an upper section that is a substantially straight-walled cylinder and a lower section that is a tapered cylinder. Such tapered configurations can ease installation and / or enable a friction fit between the insert 108 and support base. A tapered configuration can also ease installation and / or enable a friction fit between a slug fit (which may also be a tapered cylinder) and the insert 108. The base engagement portion 508 may comprise at least one channel (e.g., with a depth extending at least partially into a thickness of the wall) or slot (e.g., with a depth extending through a thickness of the wall) formed / machined on or in the wall and configured to receive the at least one protrusion of the base 106 to restrain relative movement between the insert 108 and the base 106. The insert 108 comprises a first end and a second end, wherein the first end of the insert includes an opening adapted for receiving the slug 112 and the second end is adapted for receiving and coupling with a sensor housing 110. The sensor housing 110 is adapted to be removably coupled to the second end of the insert 108. The sensor housing 110 may also be integrally formed on or in the insert 108.

[0051] Figs. 3A-3D show various views of an exemplary support base 106. Figure 3 A shows a top view of the support base showing a cylindrical wall 306 extending upwardly from a second end of the support base 106. In the embodiment shown in the figure, the second end of the support base 106 includes a hole 312. As the support base 106 is sized to fit snugly into an indentation on a bowling ball, the hole 312 allows air to more easily escape during installation of the support base into the indentation (i.e., such that air pressure does not excessively build up in a pocket of trapped air between the support base and the indentation). The wall 306 of the base 106 includes an interior surface 316 and an exterior surface 314. Fig. 3 A shows the insert engagement portion(s) as two protrusions 308, 308a extending inwardly from the interior surface of the wall 306 of the support base 106. While the protrusions 308, 308a may be substantially identical, in the embodiment shown in the figure, the two protrusions 308, 308a are positioned opposite each other on the wall of the base 106 with one having a larger crosssection than the other (i.e., one protrusion is larger than the other). In other words, the protrusions 308, 308a are spaced substantially evenly around a circumference of the base 106. In certain embodiments, the system comprises a base having two protrusions wherein one is larger than the other. For example, the first protrusion 308 may have a first diameter that is different from (e.g., larger than) a second diameter of the second protrusion 308a. This can ensure the insert is positioned in the base in a predetermined configuration (i.e., where the insert also comprises complementary channels that are adapted to receive the relative protrusions in only one orientation, one channel adapted to receive the larger protrusion, and another channel adapted to receive the smaller of the two protrusions). By ensuring a consistent rotational orientation of the insert relative to the bowling ball across multiple throws, bowling balls, and / or bowlers, the directionality of a measurement (e.g., velocity, acceleration) may be consistently determined.

[0052] Including a plurality of corresponding engagement portions (i.e., a plurality of insert engagement portions on the base that correspond to a plurality of base engagement portions on the insert) also improves structural support of the system 100. Thus, such an exemplary system is less likely to fracture during installation, use (e.g., throwing the bowling ball with the system inserted therein), and removal. The insert engagement portion(s) may be relatively sized in any configuration, spaced at any interval on the wall, and disposed on any portion of the wall so long as at least one of the insert engagement portions is engageable with at least one of the base engagement portions of the insert.

[0053] Fig. 3B is a bottom view of the support base showing its circular cross-sectional shape and the hole 312 in the second end 304. Figure 3C is a side view of the support base 106 showing the wall 306 thereof. Figure 3D is a side section view of the support base 106, showing two protrusions 308, 308a extending inward from opposing sides of the support base wall. This view also shows the protrusions having two different sizes with one being larger than the other.

[0054] Figs. 4A-4D show various views of an insert and sensor housing system 400 comprising an insert 108 and a sensor or sensor housing 110. The sensor housing 110 may be integrally formed on the insert 108, or the sensor or sensor housing 110 may be coupled (e.g., removably coupled) to the insert 108. Fig. 4A is an isometric view of the system 400. In embodiments such as that shown in Fig. 4A, the insert 108 includes a base engagement portion 508 having a substantially vertical portion 512 and a substantially horizontal portion 514. The horizontal portion 514 includes a proximal end 530 that is proximal to the vertical portion 512 and a distal end 532 opposite the proximal end 530. The base engagement portion 508 includes a locking feature 528 disposed between the proximal end 530 and the distal end 532. The locking feature 528 is configured to restrain relative movement between the insert 108 and the base 106 about an axis substantially parallel to the vertical portion 512. For example, when the system 100 is in an installed configuration, an insert engagement portion 308 of the base 106 may be disposed between the locking feature 528 and the distal end 532 of the horizontal portion 514 of the base engagement portion 508. In such a configuration, the locking feature 528 restrains the insert 108 from freely rotating relative to the base 106. The locking feature 528 may be designed to achieve a desired install torque required to install the insert 108 into the base 106 and / or to achieve a desired removal torque required to remove the insert 108 from the base 106.

[0055] Installation of the insert 108 comprises causing protrusion 308 of the base 106 to travel in a locking direction relative to the insert 108, overcoming friction between the protrusion 308 and the locking feature 528, and causing protrusion 308 to be disposed between the locking feature 528 and the distal end 532 of the horizontal portion 514. Removal of the insert 108 comprises causing protrusion 308 to travel in an unlocking direction relative to the insert 108, overcoming friction between the protrusion 308 and the locking feature 528, and causing protrusion 308 to be disposed between the locking feature 528 and the proximal end 530 of the horizontal portion 514.

[0056] In certain embodiments, the locking feature 528 is a protrusion extending from an edge (e.g., a lower edge) of the horizontal portion 514. In an embodiment, the protrusion has a height of about 1 / 32 of an inch. The locking feature 528 may be substantially in the shape of a semicircle, triangle, sawtooth, or the like. The locking feature 528 may be symmetrical, for example, such that the install torque is substantially equal to the removal torque. The locking feature 528 may be asymmetrical such that the install and removal torques are different. For example, a slope of a portion of the locking feature 528 proximal to the proximal end 530 of the horizontal portion 514 may be greater than a slope of a portion of the locking feature 528 proximal to the distal end 532 of the horizontal portion 514 such that the install torque is greater than the removal torque.

[0057] In embodiments where the sensor or sensor housing 110 is coupled to the insert 108, the insert 108 comprises a first guide portion 516 configured to interface with a second guide portion 602 of the sensor or sensor housing 110, for example, to aid coupling of the insert 108 and sensor or sensor housing 110. For example, coupling may be aided by aligning locking features on the insert 108 and sensor housing 110. In certain embodiments, the system 400 may be inserted into or adhered to an indentation 104 of a bowling ball 102 (i.e., without a support base 106). Fig. 4B is a front view of an exemplary system 400. Fig. 4B also shows a sensor housing 110 coupled to the second end of the insert 108. In this embodiment, the system 400 comprises a lower portion 404 (e.g., comprising the guide portion 516 of the insert 108) and an upper portion 402 (e.g., comprising a cavity receiving a slug 112). In this embodiment, the lower portion 404 has a size (e.g., a diameter) that is smaller than that of the upper portion 402. Figure 4C is a back image of an exemplary insert with a sensor housing coupled thereto. Fig. 4D is a side view of the insert showing an upper portion of one of the channels and the sensor housing coupled to the second end of the insert. In certain exemplary embodiments, the insert is adapted to accommodate a range of slug outer diameter sizes ranging from about 1 inch to about 1-3 / 8 inches or more, including about 1-1 / 8 inch, 1-1 / 4 inch, and 1-3 / 8 inch. In certain exemplary embodiments, the insert is adapted to receive a 1-3 / 8 inch slug and the slug is drilled to accommodate the size appropriate for the user.

[0058] As shown in Fig. 4A, the insert 108 may comprise a cylindrical wall with at least one channel (here, two) formed in the wall for receiving the protrusions of the support base 106. Here, the at least one channel(s) are spaced substantially evenly around the wall. As previously mentioned, in certain embodiments, the channels in the insert wall can be sized and shaped toonly accept one of the at least one protrusions on the support base (i.e., the larger protrusion will only fit within a larger guide channel, whereas a guide channel having a smaller width can accommodate the smaller of the two protrusions). In this way, the support base 106 and insert 108 can be assembled in only one relative configuration. The substantially vertical portion of the channel is configured to receive the protrusion of the base to restrain relative movement between the insert and the base along an axis substantially parallel to the substantially vertical portion of the channel.

[0059] Figures 5A-5F show various views of the insert 108. Figure 5A is a top view of the insert 108 showing a circular shape of the wall 506 and the opening 510 at the first end 502. The opening 510 is sized to receive a slug 112. Fig. 5B is a bottom view of the insert 108 showing the second end 504 of the insert. Also shown are slots 508, 508a having openings 526, 526a, respectively, at the second end 504 of the insert 108 such that the slots 508, 508a can receive insert engagement portions (e.g., protrusions) on the base. Also shown in Fig. 5B is a lower surface 524 of the second end 504 of the insert 108. One or more locking features, such as the first locking feature 522 and second locking feature 522a of Fig. 5B, are disposed on the lower surface 524. In certain embodiments, the locking feature may be a protrusion, such as the hemispherical protrusion 522 shown in Fig. 5B. In an embodiment, the protrusion may have a diameter of about 1 / 16 of an inch and / or a height of about 1 / 32 of an inch. During or upon coupling of the sensor housing 110 to the insert 108, the protrusion 522 is configured to be disposed within a corresponding (i.e., similarly shaped and sized) indentation on the sensor housing 110 such that relative movement between the insert 108 and the sensor housing 110 is restrained, for example, in a direction substantially parallel to the lower surface 524 of the second end 504 of the insert. In other words, the sensor housing 110 is restrained from moving relative to the insert 108 until a minimum force is applied in a direction substantially parallel to the lower surface 524. For example, the minimum force may be greater than typical forces experienced by a bowling ball during bowling play. The first locking feature(s) and second locking feature(s) may also be designed such that the force required to remove the sensor housing 110 is less than a maximum force, for example, defined by the amount of force an adult user can apply with two hands, one hand, or one thumb or other finger. Those of ordinary skill in the art would understand that the first locking feature(s) and second locking feature(s) could be sized, shaped, and included in quantities and locations such that the removal force is between the minimum force and maximum force.

[0060] In some embodiments, the locking feature on the lower surface 524 of the insert 108 may be an indentation, such as a hemispherical indentation. The indentation may have a diameter of about 1 / 16 of an inch and / or a depth of about 1 / 32 of an inch. In those embodiments, during or upon coupling of the sensor housing 110 to the insert 108, the indentation is configured to receive a corresponding (i.e., similarly shaped and sized) protrusion on the sensor housing 110 such that relative movement between the insert 108 and the sensor housing is restrained. Also shown in Fig. 5B are one or more first guide portions 516, 516a (e.g., rails) that are designed to interface with a second guide portion (e.g., a channel) on the sensor housing 110, for example, to aid coupling of the insert 108 and sensor housing.

[0061] Fig. 5C is a front view of the insert 108 showing the wall 506 disposed between the first end 502 and the second end 504. A slot 508 is formed on the wall (e.g., such that the slot 508 extends through a thickness of the wall). A second slot 508a disposed opposite the slot 508 is visible through the aperture of the slot 508. The first slot 508 and second slot 508a may be spaced substantially evenly around a circumference of the wall 506 of the insert 108.

[0062] The channel or slot 508 starts at a point closer to the second end 504 with a large width that narrows to a width the corresponds to that of one of the protrusions on the support base 106 as the channel or slot 508 extends upwardly / vertically toward the first end 502. The channel or slot 508 redirects to a substantially horizontal portion 514 through a curve. In this way, the channel or slot 508 and corresponding protrusion on the support base 106 work to restrain relative movement between the support base 106 and insert 108. In certain embodiments, the slot 508 includes an opening 526 at the second end 504 of the insert 108. The opening 526 is configured to receive an insert engagement portion of the base. The slot 508 comprises a substantially vertical portion 512 and a substantially horizontal portion 514. The vertical portion 512 and the horizontal portion 514 are joined together by a curved portion of the slot 508. The vertical portion 512 extends from the second end 504 of the insert 104 and is configured to restrain relative rotation between the insert 108 and the base 106 about an axis substantially parallel to the vertical portion 512. The substantially horizontal 514 portion extends from an end of the substantially vertical portion 512 that is distal to the opening 526. The horizontal portion 514 is configured to receive the insert engagement portion of the base to restrain relative movement between the insert 108 and the base 106 along an axis substantially parallel to the vertical portion 512. Also shown in Fig. 5C is a substantially vertical wall 520 of the insert 108 configured to contact a stop on a guide portion of the sensorhousing 110 such that the sensor housing 110 is not pushed past the predetermined installation position such that the corresponding locking features on the insert 108 and sensor housing 110 are misaligned. The first locking feature(s) 522, 522a of the insert 108 can be seen extending downwardly from the lower surface 524 of the second end 504.

[0063] Also shown in Fig. 5C are one or more first guide portion(s) 516, 516a each comprising at least one rail. The at least one rail of the first guide portion(s) has a beveled profile, adapted to interface with second guide portion(s) of the sensor housing and thereby restrain movement between the insert and the sensor housing during and / or upon coupling. The first guide portion 516 is adapted to couple with the sensor housing 110. The first guide portion 516 of the insert 108 comprises a rail extending substantially parallel to a lower surface 524 of the second end 504 of the insert 108 and configured to be at least partially disposed within a second guide portion of the sensor housing 110. The rail may have a cross-sectional shape that is substantially triangular. A first locking feature(s) 522, 522a (shown here as two protrusions extending downwardly from a lower surface of the second end of the insert) is configured to interface with the sensor housing 110 and restrain relative movement between the insert 108 and the sensor housing 110.

[0064] Fig. 5D is a back view of the insert 108 showing the wall 506 with the second slot 508a formed thereon. The slot 508 disposed opposite the second slot 508a is visible through the aperture of the second slot 508a. The second slot 508a includes an opening 526a at the second end 504 of the insert 108. The opening 526a is configured to receive an insert engagement portion of the base. The slot 508a comprises a substantially vertical portion 512a and a substantially horizontal portion 514a. The vertical portion 512a and the horizontal portion 514a are joined together by a curved portion of the slot 508a. The vertical portion 512a extends from the second end 504 of the insert 104 and is configured to restrain relative rotation between the insert 108 and the base 106 about an axis substantially parallel to the vertical portion 512a. The substantially horizontal 514a portion extends from an end of the substantially vertical portion 512a that is distal to the opening 526a. The horizontal portion 514a is configured to receive the insert engagement portion of the base to restrain relative movement between the insert 108 and the base 106 along an axis substantially parallel to the vertical portion 512a.

[0065] The slot 508 has a first width and the second slot 508a has a second width different from the first width. As shown in Fig. 5C, the first width may be greater than the second width.As discussed herein, an insert 108 with differently sized slots corresponding to differently sized protrusions on a base 106 can ensure the insert 108 is positioned in the base 106 in a predetermined configuration (and not in a rotationally misaligned configuration that may skew sensor measurement results). Moreover, The openings 526, 526a of the slots 508, 508a may be tapered, chamfered, filleted (as shown in Figs. 5C and 5D), or otherwise formed to aid location of an insert engagement portion of a base into the base engagement portion of the insert. Including a plurality of corresponding engagement portions (i.e., a plurality of insert engagement portions on the base that correspond to a plurality of base engagement portions on the insert) also improves structural support of the system 100. Thus, such an exemplary system is less likely to fracture during installation, use (e.g., throwing the bowling ball with the system inserted therein), and removal.
