Description

TECHNICAL FIELD

This document pertains generally, but not by way of limitation to molded objects or sports apparatus, such as hockey pucks. Examples described herein may include embedded additives that facilitate tracking of the object for sensing a scoring event.

BACKGROUND

Hockey is a fast moving sport that involves passing a puck beyond a goal line to score a goal. In some cases, the sport is so fast moving that it is difficult to determine if a goal has been scored. There are particular rules to adhere to that determine if a goal was successfully scored that make the ability to view the puck important.

The current method of visually determining if a goal has been scored, has limitations. The ability to reliably determine if a goal has been scored may be limited by the viewing angle and may often be obstructed by players and other obstacles between the referee or video cameras and the puck. Video cameras may be useful in replaying the event, but even video cameras having a direct line of site may be limited by frame rate in such fast-moving sports.

DETAILED DESCRIPTION

A technical problem faced in scoring fast moving sports games is reliably determining if the sports apparatus has passed the goal line and a goal has been scored. For example, in the fast moving sport of hockey, visual view of the puck may be occluded by players or other obstacles in the way of referees and video cameras. Technical solutions described herein include incorporating additives into the mold of an object. In various embodiments, the additive may include passive electronics (e.g., electronic object) or doping materials that may be sensed by sensing technology. In various examples, the sports apparatus is shown and described as a hockey puck, however, examples described herein may be used with other sports apparatus to score other sports games. Features of the disclosure may be incorporated into other sports apparatus including, but not limited to lacrosse balls and other apparatus that have solid or mostly solid cores.

The following description and the drawings sufficiently illustrate specific examples to enable those skilled in the art to practice them. Other examples may incorporate structural, logical, electrical, process, and other changes. Portions and features of various examples may be included in, or substituted for, those of other examples. Examples set forth in the claims encompass all available equivalents of those claims.

In a broad overview of this disclosure, FIGS. 1A and 1B, and FIGS. 2A and 2B show illustrative examples of a sports apparatus that may include a body formed of a substrate material and an embedded additive in the form of an electronic object for sensing a scoring event.

In another illustrative example of a sports apparatus, to be described later with respect to FIGS. 5, 6, 7A, 7B and 8, the sports apparatus may include a body formed of a substrate material where the embedded additive may be in the form of a doping material for sensing a scoring event.

The various examples provided herein describe different types of additives such as the electronic object or the doping material. While these additives are described separately in separate examples, a sports apparatus including more than one additive, such as a sports apparatus having both an electronic object and a doping material embedded therein, is within the scope of this disclosure.

The substrate material in any of the examples may include natural rubber, antioxidants, bonding materials and other chemicals to achieve a balance of hardness and resilience. Any suitable materials may be used as the substrate material. The materials and proportions of the materials may be selected so as to meet regulation sports apparatus specifications.

FIGS. 1A and 1B show side and top views, respectively, of an illustrative example of the sports apparatus 100, according to an embodiment. As shown in the example of FIGS. 1A and 1B, the sports apparatus 100 includes a body 114 formed of a substrate material 102 and an additive 120 embedded in the substrate material 102. The additive 120 may be used by a sensor array to locate the position of the sports apparatus 100 in relation to a sports goal, such as a hockey goal.

In some examples, including the example illustrated in FIGS. 1A and 1B, the additive 120 may be an electronic object, such as a non-powered passive electronic object. The electronic object may include but is not limited to, radio-frequency identification (RFID) objects, or electromagnetic objects, receivers, transceivers, coils or antenna. Any suitable marker, tag or other object(s) may be used as a part of the additive 120, or as the additive 120. In some examples the electronic object may be a powered electronic object or an active powered electronic object. The term electronic object may refer not only to a single object but a combination of connected or discrete elements.

To securely embed the additive 120 within the sports apparatus 100, the present disclosure provides particular features, which when employed, lock the additive 120 into the body 114 of the sports apparatus 100. Even under the strenuous conditions encountered during a game, features of this disclosure prevent the embedded additive 120 from separating from the body 114 of the sports apparatus 100, or being unduly exposed to forces that would damage the additive 120.

As shown in the examples of FIGS. 1A and 1B, the substrate material 102 includes a first substrate 110 and a second substrate 130. Together, the first and second substrates 110, 130 cooperate to form the body 114 of the sports apparatus 100. In the example of a hockey puck shown in the figures, the first and second substrates 110, 130 may form a generally cylindrical shape extending along a longitudinal axis 10.

In the illustrative example, the first substrate 110 includes a shape that forms a portion of the sports apparatus 100. The first substrate 110 also includes features to permit the additive to be securely embedded in the sports apparatus 100. As perhaps best shown in FIGS. 1A and 1B, the first substrate 110 may include a first surface 104 opposite a second surface 106, and a circumferential outer surface 108 extending from the first surface 104 to the second surface 106. Also illustrated in FIGS. 1A and 1B, and further supported in FIG. 3A, the first surface 104 may include a recess 140 formed in the first surface 104 that is configured to accommodate the additive 120, and may also include an overhang 112. In addition to accommodating the additive 120, the recess 140 may be configured to receive at least a portion of the second substrate 130 therein. In this arrangement, the additive 120 is located in the recess 140 and is sandwiched between the first substrate 110 and the second substrate 130 (FIG. 1A).

As shown in the example of FIGS. 1A and 1B, with additional support in FIG. 3A, the recess 140 may vary in cross-section. For example, the recess 140 may have a stepped cylindrical shape. In other words, the recess 140 may be formed as a circular or cylindrical recess 140 having different diameters at different locations along the longitudinal axis 10 of the storage apparatus. For example, the recess 140 may have a first diameter 132 (FIG. 1B) at a first location or region 32 (FIG. 1A) along the longitudinal axis 10, and a second diameter 134 (FIG. 1B) at a second location or region 34 along the longitudinal axis 10 (FIG. 1A). The diameters 132, 134 are most easily viewed in FIG. 1B, which depicts a top view of the sports apparatus 100. The first and second locations or regions 32, 34 which show where the change in diameter may occur along the longitudinal axis 10 is most easily viewed in the side view of FIG. 1A. As shown in the example of FIGS. 1A, and 1B, the first diameter 132 may be located closer to the outermost surface of the first surface 104 than the second diameter 134, and the first diameter 132 may be smaller than the second diameter 134. The diameter may be defined along a plane orthogonal to the longitudinal axis 10 of the recess 140.

The examples of FIGS. 1A and 1B, depict the recess 140 having a circular cross-section (e.g., having a diameter). Whether the recess 140 is circular in nature or another shape, the recess 140 may also be described as having different cross-sectional areas at different points along the longitudinal axis 10 of the sports apparatus 100. For example, the recess 140 may include a first cross-sectional area (e.g., 132) at the first location or first region 32 along the longitudinal axis 10 of the recess 140, and a second cross-sectional area (e.g., 134) at a second location or second region 34 along the longitudinal axis 10. The recess 140 may be formed such that the first cross-sectional area 132 is different from the second cross-sectional area 134. In the example of FIGS. 1A and 1B, the first cross-sectional area 132 may be smaller than the second cross-sectional area 134. The first location or the first region 32 may be located closer to the outermost portion of the first surface 104 than the second location or the second region 34. In other words, the first location or the first region 32 may be located more distal from the bottom of the recess 140 than the second location and the second region 34. The cross-sectional area may be defined along the plane orthogonal to the longitudinal axis 10 of the recess 140.

In some examples, the recess 140 may have a non-circular cross-section. In such an example the recess 140 may also be described as having different cross-sections (e.g., different cross-sectional shapes) at different points along the longitudinal axis 10 of the sports apparatus 100. For example, the recess 140 may include a first cross-section (e.g., 132) at a first location or first region 32 along the longitudinal axis 10 of the recess 140, and a second cross-section (e.g., 134) at a second location or second region 34 along the longitudinal axis 10. The recess 140 may be formed such that the first cross-section is different in size, shape or orientation than the second cross-section. In the example of FIGS. 1A and 1B, the first cross-section may be smaller than the second cross-section. The first location or the first region 32 being located more distal from the base of the recess 140 than the second location or the second region 34. The cross-section may be defined along the plane orthogonal to the longitudinal axis 10 of the recess 140.

In some examples, and as shown in FIG. 1A, the recess 140 may be described as being formed in the first surface 104 of the first substrate 110 such that the recess 140 includes a combination of a longitudinal recess 142 and an axial recess 144 (FIGS. 1A and 3A). The longitudinal recess 142 extending along the longitudinal axis 10. Further, the recess 140 may include a portion having the axial recess 144 extending along a portion of the longitudinal recess 142. The axial recess 144 extend axially away from the longitudinal axis 10 such that an axial recess 144 is also formed in the first substrate 110 of the sports apparatus 100 in addition to the longitudinal recess 142.

The recess 140 may be formed in any suitable shape that securely embeds the additive 120 within the sports apparatus 100. In other examples, the first and second substrates 110, 130 and the recess 140 may take on other shapes, while incorporating the additive 120 embedding features presented here and still remain within the scope of the invention. For example, it is contemplated that in some examples, the first and second cross-sections may be different in shape from each other, but the same in cross-sectional area. Vice-versa, it is contemplated that the first and second cross-sections could be the same in shape as each other, but different in cross-sectional area. Different configurations between the portion of the recess 140 in the first region 32 and the portion of the recess in the second region 34 that result in the second substrate 130 being locked into the first substrate 110 are considered to be within the scope of this disclosure.

As shown in the illustrative example of FIGS. 1A and 1B, the additive 120 may be locked into the recess 140 of the first substrate 110 by the second substrate 130. In FIGS. 1A and 1B, the second substrate 130 may occupy all or at least a portion of the recess 140 that is not occupied by the additive 120. In this example, the second substrate 130 may be described as including a stepped cylindrical form having a first portion (e.g., at 32) and a second portion (e.g., at 34), where the second portion 34 may have a larger diameter than the first portion 32.

The first substrate 110 and the second substrate 130 join at the first surface 104 along a seam 160. The location of this seam 160, although on a surface viewable by the user, may be desirable because while it is located on the first surface 104, the seam 160 may be arranged so that it is easy to blend in or be covered up by a printed logo.

FIGS. 1A and 1B depict merely one example of the sports apparatus. The shape of the recess 140 in the first substrate 110 and the shape of the second substrate 130 may take on other forms other than the shapes shown in FIGS. 1A and 1B. FIGS. 2A and 2B, which share many similarities with the example of FIGS. 1A and 1B, show another example of a sports apparatus 200. The disclosure of FIGS. 1A and 1B may be applied to the example of FIGS. 2A and 2B, with like numerals representing like elements.

In the example of FIGS. 2A and 2B, the sports apparatus 200 may include a body 214 formed of a substrate material 202 that may include a first substrate 210 having a first surface 204 opposite a second surface 206 and a circumferential outer surface 208 extending from the first surface 204 to the second surface 206. Like sports apparatus 100, the first surface 204 may also include a recess 240 in the first surface 204 that is configured to accommodate an additive 220. The first substrate 210 also having an overhang 212.

The first substrate 210 may be generally similar to the sports apparatus described in FIGS. 1A and 1B. However, the recess 240 is shown having diameters 232, 234 that may vary more continuously or gradually along a longitudinal axis 20 than the example depicted in FIGS. 1A and 1B. In addition to the differences in recess 240 compared to recess 140, a second substrate 230 may also be formed having a more continuously varying cross-section than was shown with respect to the second substrate 130 of FIGS. 1A and 1B.

The diameter of the recess 240 in FIGS. 2A and 2B is shown as varying more continuously than stepped like the recess 140 of FIG. 1A. In other words, the characteristics of a variable diameter, variable cross-sectional area or variable cross-section (e.g., cross-sectional shape), as described with respect to the example of FIGS. 1A and 1B may apply, but here the variation may be more continuous. Like the more continuous variation along recess 240, the substrate 230 may also vary in diameter, cross-sectional area or cross-section shape or size, etc. in a more continuous manner than in FIG. 1.

In the example of FIGS. 2A and 2B, the second substrate 230 may be generally formed as a portion of a cone extending from the first surface 204 to the second surface 206. When the illustrative second substrate 230 of FIGS. 2A and 2B is formed in the recess 240 of the first substrate 210, an additive 220 located therein may be described as being locked into the first substrate 210 by the second substrate 230.

The examples of FIGS. 1A and 1B, and 2A and 2B demonstrate two of many possible arrangements of the geometry of a first substrate 110, 210, a recess 140, 240 and a second substrate 130, 230 that are within the scope of this disclosure. Other geometric shapes of recesses and second substrates that cause an additive to be locked into the first substrate, including combinations of stepped and continuous variations along the longitudinal axis of the recess and the second substrate, are considered to be within the scope of the present disclosure.

Features of the invention, including the recess 140, 240 and the second substrate 130, 230, may be incorporated into other sports apparatus besides a hockey puck. Such apparatus include but not limited to, a lacrosse ball. In the case of a lacrosse ball, the shape of a recess may be incorporated into a first substrate. The first substrate may be formed as a portion of a sphere, and the second substrate may be formed as another portion of the sphere. Like the examples of FIGS. 1A, 1B, 2A and 2B, at least a portion of the second substrate may fit within the recess of the first substrate such that when molded together, the first and second substrates form the ball with the additive 120 sandwiched between the substrates and embedded therein in a locking manner.

An illustrative example of a manufacturing method 400 for a sports apparatus will now be described with reference to FIGS. 3A-3D which show side views of manufacturing operations of a method 400 and FIG. 4 which shows an illustrative flow chart of the method 400.

The method 400 may be used in accordance with at least one of the example sports apparatus described herein, including, but not limited to, the sports apparatus 100 of FIGS. 1A and 1B, or the sports apparatus 200 of FIGS. 2A and 2B. For the purposes of illustration, the method 400 will be described as applied to the sports apparatus 100 of FIGS. 1A and 1B. The method 400 may also be used with other sports apparatus.

In operation 410 of FIG. 4 and as depicted in FIG. 3A, the first substrate 110 may be received, for example, at an assembly station or in a mold 190. In some examples, the first substrate 110 may be received in a raw material state, or in a pre-formed state already including the recess 140. Receiving as described herein may include any of receiving, providing and/or forming the first substrate from a raw substrate, a substrate blank a substrate, pre-form, or a substrate that is in its final form. In other words, receiving any of the substrate materials may include or exclude forming operations to convert the substrate material to another form.

In some examples, receiving the first substrate may also include forming the first substrate 110 from a blank material to a pre-form or intermediate form having the substantially cylindrical shape including the first surface 104 opposite the second surface 106, and the circumferential outer surface 108 extending from the first surface 104 to the second surface 106. This operation may also include forming the recess 140 into the first surface 104. The formed recess 140 may be arranged to accommodate the additive 120 and at least a portion of the second substrate 130 therein.

Receiving the first substrate 110 may include receiving multiple pieces of substrate, including substrates that may have been partially, but not necessarily completely formed into the sports apparatus 100. In some examples the shape of the first substrate 110 may be similar to the shape of the final components, but the first substrate 110 may also be different from the shape of the final components. In some cases, one or more of the pre-forms may even be substantially the same as the final components or the same as the final components. In some other examples, the substrate may be a raw material. A substrate may also refer to any one of multiple different forms or pre-forms that the components take on at various points during the manufacturing process. Receiving the first substrate may also include receiving a pre-form in the form of a blank or extruded form (e.g. the product of a pultrusion machine) that requires further being cut or formed into multiple pre-forms.

In operation 420 and as shown in FIG. 3B the additive 120, may be received, for example at the assembly station or mold 190, and in operation 430 the additive 120 may be inserted into the recess 140 in the first substrate 110.

In operation 440 and as shown in FIG. 2C, the second substrate 130 may be received, and in operation 450 the second substrate 130 may be inserted into the recess 140, sandwiching the additive 120 between the first substrate 110 and the second substrate 130.

As described above with respect to receiving the first substrate 110, the second substrate 130 may also be received in a shape that is ready for insertion into the recess, or may require additional forming. For example, the shape of the received first and second substrates 110, 130 may be similar, different, the same or substantially the same shape as the form of the final components. As shown in the example of FIG. 3C, the second substrate 130 may be inserted into the recess 140 with a portion of the second substrate 130 remaining above the first surface 104 of the sports apparatus 100 (FIG. 3C).

In some examples, the second substrate 130 may be coupled to the additive 120, which may be coupled to the second substrate 130 before insertion into the recess 140 such that the additive 120 and the second substrate 130 are inserted into the recess 140 jointly. For example, the additive 120 may be molded or adhered to the second substrate 130. In some examples, the additive 120 may instead be adhered to the first substrate 110 (e.g., by an adhesive or interlock) to hold the additive 120 in place during manufacturing and/or use in sports.

Operation 460, shown in FIG. 3D, may include forming the substrate material into the body of the sports apparatus 100. In some examples, forming the substrate material 102 into the body of the sports apparatus 100 may include: molding the second substrate 130 while the second substrate 130 is located in the recess 140 (FIG. 3C) of the first substrate 110. This allows the second substrate 130 to be formed together with the first substrate 110 such that the final form locks the second substrate 130 into the first substrate 110 to retain the additive 120 within the sports apparatus 100.

In some examples the forming operation 460 may be a vulcanized rubber forming process. In other examples, one or both of the first and second substrates 110, 130 may be formed by other processes and materials including injection molding or other known processes and materials.

Various machines and processes may be used to manufacture the sports apparatus 100 by machine and/or by hand are described herein. The means may include one or more of: means for receiving, means for forming or molding, means for inserting, means for distributing, means for generating a magnetic field, means for exposing the sports apparatus to the magnetic field, means for heating and controlling heating, means for compressing, and means for controlling the manufacture. The means for controlling the manufacture may include a computer or machine readable medium having instructions for manufacturing the sports apparatus 100, that responsive to being executed with processing circuitry of a computer-controlled device, cause the computer controlled device to implement operations of the method 400.

The operations of the method 400 that may be controlled include, but are not limited to: receiving operations, molding operations including molding operations performed with a mold (similar to mold 190 shown in FIGS. 3A-3D), closing and opening operations, determining material characteristics operations, timing operations, temperature controlling operations, determination of presence operations. Inputs to the computer controlled device may include input and determination operations where input is provided by a user, switch and/or sensor.

The means for receiving the substrate material 102 may include receiving the substrate material 102 from a substrate material manufacturer or distributer. The means for receiving the substrate material 102 may also include receiving the substrate material 102 into the mold 190, wherein the mold 190 may have one or more components having the shape of the sports apparatus 100. The means for receiving, as all the means described herein, may be automated by a machine, completed by a worker, or a combination thereof. The means for receiving may also include a machine or worker that receives the additive 120. Receiving the additive 120 may include inserting the additive 120 into the substrate material 102.

The means for forming the substrate material 102 into a body 114 of the sports apparatus 100 with the additive 120 embedded therein may include a forming machine such as a molding machine. The molding machine may be capable of compressing the substrate material 102. In some examples the molding machine may also be capable of heating the substrate material 102. In some examples the means for forming or molding is a vulcanized rubber forming machine capable of applying compression and/or heating.

In some examples, the means for forming may include an injection molding machine. Any means for forming that is capable of forming the sports apparatus 100 to the desired specifications may be used for any of the forming or molding operations described herein with respect to various examples. Intermediate forming operations may be included in the means for forming, including forming an elongate form by a pultrusion machine, which is then cut into individual blanks followed by additional manufacturing operations.

The means for inserting the additive 120 may include automated insertion of the additive by a machine, or manual insertion of the additive 120 by hand.

In the illustrative example of FIG. 5, a sports apparatus 500 includes an additive 520, such as a doping material embedded in the substrate material 502 that forms the body 514 of the sports apparatus 500. The additive 520 may induce a specified magnetic moment 590 (FIGS. 7A, 7B and 8) within the sports apparatus 500, wherein the specified magnetic moment 590 is adapted to be used for tracking location and orientation of the sports apparatus 500. In particular, the additive 520 may have an induced magnetism having a characteristic dipole moment that permits the location of the sports apparatus 500 to be determined by one or more sensors.

Example doping materials may include at least one of: a manganite material, a ferrous material, a rare earth magnetic material, or a combination thereof. The doping material may have a Curie temperature that is less than the bake temperature of the substrate material 502 of the body 514 of the sports apparatus 500 to prevent the specified magnetic moment 590 from being damaged during manufacturing. For example, the Curie temperatures of neodymium magnets (rare earth magnets) may generally be between 100° Celsius (° C.) and 200° C., which are common, very strong, and available for doping. The vulcanizing temperature for most rubber is around 175° C., therefore some rare earth magnets will work, be cheap and readily available, and exist in a doping form. Other magnetic materials exist in the range of −240° C. to 1000° C. in Curie temperature, however the magnetic materials having a Curie temperature at <0° Celsius are pretty rare and expensive.

In some examples the additive 520 may be provided in particulate or powder form. In at least one example, a powder may be defined as particle sizes between 5 nanometers (nm) −120 micrometers (μm). In a more preferred embodiment, the particle size may be between 2 μm-50 μm.

In some examples, the additive 520 forms between 0.05-3.0% of the body 514 of the sports apparatus 500 by volume or weight. In a preferred example, the additive 520 may form less than 1% of the body 514 of the sports apparatus 500 by volume or weight. A preferred range of the additive amount may be between 0.05% and 1.0%. The amount of additive is selected to provide the necessary tracking capabilities, without being so concentrated as to cause the sports apparatus such as a puck to be attracted to and stick to skate blades and other metal objects.

The additive 520 may be mixed into the substrate material 502 according to any suitable method (e.g., method 400 of FIG. 4). In some examples, the additive 520 may be mixed into the substrate material 502 by a machine having adjacent metal rollers that turn in opposite directions. The substrate material 502 may include natural rubber, antioxidants, bonding materials and other chemicals to achieve a balance of hardness and resilience. In order to account for the additional additive 520 characteristics, the mix of the substrate material 502 may be modified over the substrate material use in a conventional sports apparatus to achieve the characteristics required to meet regulation sports apparatus requirements.

Operation 610A may include receiving the substrate material 502 and operation 610B may include receiving the additive 520. In some examples, receiving the substrate material 502 and receiving the additive 520 may include receiving a substrate material 502 having an additive 520 already distributed therein. If the substrate material 502 and the additive 520 are not yet combined, operation 620 may include distributing the additive 520 into the substrate material 502.

Operation 630 may include forming the substrate material 502 into the shape of the body 514 of the sports apparatus 500. In some examples, forming the substrate material 502 may be accomplished by molding. Molding may be performed by inserting the substrate material 502 into a mold (such as the mold 190 in FIG. 3D), closing the mold 190 and applying pressure (e.g., FIG. 3D, 170). The molding process may include heating and/or compressing the substrate material 502. Previous aspects of the forming or molding operations described with respect to the example sports apparatus 200 and associated method 400 may be applicable.

The molding process may be controlled by at least one machine-readable medium that includes instructions for manufacturing a sports apparatus 500 that, responsive to being executed with processing circuitry of a computer-controlled device, causes the computer-controlled device to receive information about a presence of a substrate material 502 and the presence of and an additive 520 in a mold 590. The mold 590 being shaped to produce a body 514 of a sports apparatus 500.

Upon receiving information that the substrate material 502 and the additive 520 are in the mold (e.g., such as mold 190 of FIG. 3D), the mold is caused to be closed to form the substrate material 502 into the body 514 of the sports apparatus 500 and to apply compression and/or heating to do so. The temperature to which the mold is heated may be determined, at least in part, based on the bake temperature of the substrate material 502 and the Curie temperature of the additive 520. In some examples, the instructions may include that upon a determination that the sports apparatus 500 has been formed, cooling of the sports apparatus 500 may be initiated.

Once the body 514 of the sports apparatus 500 is formed with the additive 520 embedded therein, operation 640 of the method 600 may include determining if a material characteristic of the sports apparatus 500 has reached a specified material characteristic. If it is determined that the specified material characteristic has been reached, operation 640 may include reducing or discontinuing the heat and or pressure applied to the substrate material 502 during the molding process and to allow the sports apparatus 500 to cool or relax. The material characteristic may be determined by any suitable material characteristic sensor or other input.

The specified material characteristic of operation 640 may be any material characteristic. In the example method 600, the material characteristic may be temperature. The determination of temperature may be determined via data received from a temperature sensor, the instructions to determine if the material characteristic has reached a specified material characteristic may include determining if the sports apparatus 500 has reached a specified temperature during the cooling process.

In some examples, a determination of temperature may be based on measured data, in other examples, the determination of temperature may be based on empirical data related to when the sports apparatus 500 is expected to reach a desired temperature. For example, the instructions may include instructions to determine if the material characteristic has reached a specified material characteristic based on the amount of time that has elapsed since cooling of the sports apparatus 500 was initiated, the ambient temperature in the room, or other factors.

Operation 650 may include generating a magnetic field 570 (if such a field is not already present), and exposing the sports apparatus 500 to the magnetic field 570 to induce a specific magnetic moment 590 within the sports apparatus 500. In some examples, the temperature determination and the cooling process may be an important aspect in inducing a specific magnetic moment 590 within the apparatus 500. The combination of the additive 520 and the exposure to the magnetic field 570 result in the sports apparatus 500 having a magnetic moment 590 that may be adapted to be used for determining at least one or both of location and orientation of the sports apparatus 500.

When molding is complete and the heat is discontinued or removed, the additive 520 (e.g., magnetic material) cools back down. Before the sports apparatus 500 reaches the Curie temperature, the application of the magnetic field 570 may uniformly or locally induce the magnetic moment 590. The magnetic field 570 may continue to be applied as the sports apparatus 500 is cooled below the Curie temperature, leaving the magnetic moment 590 permanently fixed in a given configuration.

For this reason, exposing the sports apparatus 500 to the magnetic field 570 may include exposing the sports apparatus 500 to a specified magnetic field 570 at a specified temperature, or within a range of specified temperatures. In some examples, the Curie temperature of the additive 520, and the bake temperature of the substrate material 502 are important factors. Those material characteristics may be used to determine the optimal temperatures at which to mold the sports apparatus 500 and/or the optimal temperature to expose the sports apparatus 500 to the magnetic field 570. For example, the instructions to determine if the material characteristic has reached a specified material characteristic may be based, at least in part, on the Curie temperature of the doping material.

The method 600 may be performed by a manufacturing apparatus or system comprising means for performing any of the operations of the method 600 as described herein. Further, the method 600 may be performed by at least one computer-readable medium comprising instructions to perform any of the operations of the method 600. The computer-readable medium may include a non-transitory computer-readable medium.

For example, the method 600 for manufacturing a sports apparatus 500 may include a means for receiving a substrate material 502 such as a mold (e.g. mold 190). The method 600 may also include a means for receiving an additive 520 which may be in the form of a doping material. The additive 5:20 may be used by a sensor array to locate the position of the sports apparatus 500 in relation to a sports goal. The method 600 may also include a means for forming the substrate material 502 into a body 514 of the sports apparatus 500 with the additive 520 embedded therein. The means for forming may include a molding machine, including a first portion of a mold cavity in combination with a second portion of a mold cavity (e.g. 190, FIG. 3D). The means for forming may include vulcanized rubber forming.
