This disclosure relates to (i) systems and methods for acquiring, storing and processing a player's unique data, namely the player's anatomical features, where that player is to wear a protective sports helmet, (ii) for systems and methods of using the player's unique data to manufacture a protective sports helmet with a custom formed internal padding assembly that substantially corresponds to the player's unique data, and (iii) a protective sports helmet designed using the acquired and processed unique player's data and including the custom formed internal padding assembly that provides improved fit and comfort for the player. Accordingly, the disclosure provides for a system and method to design and manufacture a bespoke protective sports helmet that is purposely designed and manufactured to match the player's anatomical specifications, namely the topography and contours of the player's head and facial region, including the jaw region.
Most, if not all, contact team sports require players to wear protective equipment, such as a helmet, while playing the sport during both practice and game play. For example, youth, high school, club, college and professional levels of football, lacrosse, hockey, baseball and softball require players to wear a protective helmet. These helmets generally comprise at least two layers: a substantially rigid outer shell, typically formed from polymers and composite materials including plastics, and an internal padding assembly, which can be formed from a variety of impact absorbing materials. Most protective helmets for contact team sports also include a chin strap that secures the helmet on the player's head during the course of play such that helmet is not dislodged when the player and/or helmet receives a first impact whereby the helmet is properly positioned to protect the player from a second impact. Football and lacrosse helmets also include a face guard or face mask that overlie the player's facial region. Hockey helmets typically include a face guard, or clear shield that overlies at least the player's eye region. Baseball batter's helmets typically are “open-faced” and thus lack a face guard, although baseball catcher's helmets include a face guard to protect the catcher. Unlike baseball batter's helmets, softball batter's helmets include a face guard, which typically extends over the player's mouth and jaw region while leaving the eye region open.
Conventional protective equipment, including helmets can be found in multiple standard sizes depending upon the playing level—youth, varsity or professional—to which the helmet is intended for use. For example, youth level football helmets can be found in a number of standard sizes, including extra-small, small, medium, large and extra-large, where the helmet size is based upon the circumference of the player's head. Similarly, varsity and professional level football helmets can be found in a number of standard sizes, including small, medium, large and extra-large, where again the helmet size is based upon the circumference of the player's head. For example, a “medium” varsity level football helmet is sized for a player having a head circumference of 20.375-22.0 inches, a “large” varsity level football helmet is sized for a player having a head circumference of 22-23.5 inches, and an “extra large” varsity helmet is sized for a player having a head circumference of 23.5 inches and above. The football helmet's external shell and internal padding assembly are configured to receive a player's head, so a particular helmet size is selected for a player based upon his/her head size, namely his/her head circumference. When properly sized, the football helmet should provide a secure fit on the player's head and be comfortable, while not irritating the player when worn during the course of play.
It is not uncommon for the internal padding assembly found in conventional protective sports helmets to be comprised of multiple pad elements that can be selectively adjusted to a limited extent in order to accommodate a player's (i) head size and (ii) head contours or topography. However, the extent of that adjustment is limited in a number of ways, including that the internal pad assembly comprises an arrangement of pad elements each including an elastically deformable, energy absorbing pad member positioned within a pad housing. Thus, the internal pad assembly is configured in a standard size with maximum dimensions and the internal pad assembly must fit within a standardized helmet shell size. It is understood that the helmet shell is formed to be substantially rigid to withstand multiple impacts and the helmet shell's overall configuration cannot be greatly expanded or contracted. An example of a conventional internal padding assembly is one that features multiple pad elements each with an inflatable component that allows for a fluid, such as air, to be used to selectively inflate or deflate the pad elements to better conform the internal padding assembly to the player's head size and contours. Examples of a conventional internal padding assembly can be found in U.S. Pat. No. 6,934,971, U.S. Pat. No. 8,544,117, and U.S. patent application publication US2015000808. Conformity of the internal padding assembly to the player's head size and contours is limited by a number of factors inherent to pad elements, including, but not limited to, the size and configuration of the pad member, the size and configuration of the pad housings, and the placement of the pad elements in the padding assembly relative to the player's head. As the extent of the adjustment of a conventional internal padding assembly to the player's head contours and topography is limited, the player may perceive the fit of the helmet to be inadequate and/or may not find the fit of the helmet to be sufficiently comfortable. Thus, the player wearing a conventional protective sports helmet might not be entirely happy with the helmet, which may impact his/her selection of the helmet and his/her performance while playing the contact sport. Even if the player is happy with the comfort of the conventional helmet and accepts the conventional helmet's fit on his/her head, the helmet may not be ideally positioned and can be susceptible to excessive movement when the helmet is impacted during the course of play.
The apparatus, systems and methods disclosed herein address the problems discussed above and other problems while providing advantages and aspects not provided by conventional protective sports helmets. A full discussion of the features and advantages of the present disclosure is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
The present disclosure provides systems and methods for acquiring, storing and processing a player's unique data set concerning the anatomical features of the player's head in order to design and manufacture a bespoke protective sports helmet. The bespoke protective sports helmet can include a custom formed internal padding assembly that can be configured to match or substantially correspond to the player's unique anatomical head data. The bespoke helmet, including its internal padding assembly, provides significantly improved fit and comfort for the player. Accordingly, the disclosure provides for a system and method to design and manufacture a bespoke protective sports helmet that is purposely designed to either match or substantially correspond to the player's anatomical specifications, namely the topography and contours of the player's head and facial region, including the jaw region.
The present disclosure also provides a method for manufacturing a bespoke protective sports helmet. The method may include placing a scanning hood on a player's head, selecting a scanning helmet size and placing a scanning helmet of the selected scanning helmet size on the player's head over the scanning hood, adjusting the scanning helmet according to the player's wearing preferences, capturing a helmet scan of the player wearing the scanning hood and scanning helmet with a scanning apparatus, removing the scanning helmet from the player's head and capturing a hood scan with the scanning apparatus while the player is wearing the scanning hood, opening the helmet scan in three-dimensional software and properly aligning the helmet scan with a shell template within the three-dimensional software, opening the hood scan in the three-dimensional software and properly aligning the hood scan with the properly-aligned helmet scan within the three-dimensional software, comparing the properly-aligned hood scan with data of the scanning helmet size and determining whether scanning helmet size tolerances are satisfied for the properly-aligned hood scan, creating at least one insert file from the properly-aligned hood scan, fabricating an insert from the insert file, placing the insert into a lower mold section, attaching a backing material to an upper mold section, heating an ethylene-vinyl acetate (EVA) cover and attaching the heated EVA cover to the lower mold section, vacuum-forming the EVA cover to an insert surface, pouring padding material into the vacuum-formed EVA cover, allowing the poured padding material to cool and solidify into a customized pad, removing the customized pad from the vacuum-formed EVA cover and installing the customized pad into the customized protective sports helmet.
The disclosure also provides for a bespoke protective sports helmet fabricated from a process that comprises the numerous steps discussed in the foregoing paragraph. Other features and advantages of the disclosure will be apparent from the following specification taken in conjunction with the following drawings. Implementations of the described techniques may include hardware, a method or process, or software for a mobile device on a computer-accessible medium. The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.
Additional advantages and novel features will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following and the accompanying drawings or may be learned by production or operation of the examples. The advantages of the present teachings may be realized and attained by practice or use of various aspects of the methodologies, instrumentalities and combinations set forth in the detailed examples discussed below.
The drawing figures depict one or more implementations in accord with the present teachings, by way of example only, not by way of limitation. In the figures, like reference numerals refer to the same or similar elements.
In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present disclosure.
While this disclosure includes a number of embodiments in many different forms, there is shown in the drawings and will herein be described in detail particular embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosed methods and systems, and is not intended to limit the broad aspects of the disclosed concepts to the embodiments illustrated.
This disclosure relates to (i) systems and methods for acquiring, storing and processing a player's unique data, namely the player's anatomical features, where that player is to wear a protective sports helmet while engaged in a sporting activity, (ii) for systems and methods of using the player's unique data to manufacture a protective sports helmet with a custom formed internal padding assembly that at least substantially corresponds to the player's unique data, (iii) for systems and methods of using the player's unique data to manufacture a bespoke protective sports helmet with both a custom formed shell and internal padding assembly that match the player's unique data, and (iv) a protective sports helmet designed using the acquired and processed unique player's data and including the custom formed internal padding assembly that provides an improved fit for the player. As used herein, the term “player” is a person who wears the protective sports helmet, is gender neutral and is synonymous with the term “helmet wearer” or “wearer.” The term “anatomical features” means the dimensions, topography and contours of the player's head including the player's skull, facial region, eye region and jaw region. Because the disclosed helmet is worn on the player's head and the internal padding assembly makes contact with the player's hair, the “anatomical features” term also includes the type, amount and volume of the player's hair or lack thereof. For example, some players have long hair, while other players have no hair (i.e., are bald).
In one embodiment the disclosed helmet is “bespoke,” meaning that the internal padding assembly is custom to the player wearing the helmet because it is purposely designed, configured and manufactured to match anatomical features of the player's head. Much like a tailor provides a bespoke suit that is made to order with pants and a jacket that match the customer's specific anatomical needs (e.g., waist size, chest size, sleeve length), the system and methods disclosed allow for a bespoke protective sports helmet that provides improved fit and comfort for the player wearing the helmet. In another embodiment, the helmet is “fully bespoke,” meaning that both the helmet shell and the padding assembly are purposely designed, configured and manufactured to match the anatomical features of the player's head. In yet another embodiment, the disclosed helmet and its internal padding assembly are “partially bespoke,” meaning that the helmet and the padding assembly are purposely designed and configured to substantially correspond to the anatomical features of the player's head. In this embodiment and as explained below, the internal padding assembly of the partially bespoke helmet is comprised of an arrangement of pads that are selected from a large number of pre-manufactured pads. In all three versions—bespoke, fully bespoke and partially bespoke—highly sensitive scans of the player, with and without a helmet, are conducted to capture his/her anatomical features to help design the internal padding assembly.
The disclosed system and methods may be used to design and manufacture a bespoke protective sports helmet for a football player, hockey player, or lacrosse player or any other player in a contact sport wherein the helmet is designed and intended to receive, withstand and absorb multiple impacts during the course of play. As discussed below, the disclosed bespoke protective sports helmet for football, hockey and lacrosse players include at least two layers: (i) an outer shell typically formed from polymers and composite materials, including plastics and carbon fiber-reinforced polymers, and (ii) an internal energy attenuating assembly which is formed from cast urethane foam and is configured to match the player's head topography. The outer shell can be formed from materials that provide it with a generally rigid configuration in a pre-impact state, however, the outer shell may experience some elastic localized deformation in response to an impact or series of impacts in an impact state. Because this localized deformation is elastic, the outer shell returns to its original configuration of the pre-impact state. The disclosed system and methods may also be used to design and manufacture a bespoke protective helmet for baseball, namely a batter's helmet or a catcher's helmet, where these helmets can receive a number of high velocity impacts from a thrown or batted baseball.
Bespoke Helmet and System
In the bespoke helmet and system embodiment, the disclosed system and methods include a number of processes and sub-processes that are used to acquire and process data concerning the player's unique anatomical features and then use the processed data to manufacture a bespoke protective sports helmet, or a customized helmet, 2, exemplary shown in
A method for acquiring, storing and processing a player's unique data, namely the player's anatomical features, commences with conducting at least two scans of the player's head H and facial region F where one scan involves the player P wearing a scanning hood 10 and a scanning helmet 15, and a second scan involves the player P wearing only the scanning hood 10. A person skilled in the art recognizes that the order of the first and second scans can be reversed.
A size for the scanning helmet 15 is then selected from a range of scanning helmet 15 shell sizes. As an example for an adult player P, the scanning helmet 15 shell sizes may include medium, large and extra-large, although additional or intermediate sizes are certainly within the scope of this disclosure. The selection of the scanning helmet 15 shell size may be by determined by previous player experiences or by estimations or measurements taken during or before the acquisition of the player's unique data. Once the size of the scanning helmet 15 is selected, the scanning helmet 15 is placed over the player's head H while the player P is wearing the scanning hood 10. After the scanning helmet 15 is placed on the player's head H, the player adjusts the scanning helmet 15 to a preferred wearing position or configuration, which includes adjusting the chin strap assembly 17 by tightening or loosening it. It is not uncommon for a player P to repeatedly adjust the scanning helmet 15 to attain his or her preferred wearing position because this position is a matter of personal preference. For example, some players prefer to wear their helmet lower on their head H with respect to their brow line, while other players prefer to wear their helmet higher on their head H with respect to their brow line. The preferred wearing position is also a function of the face guard 13 and the player looking through the face guard 13 to assess the field of view.
As can be seen in
As mentioned above, the scanning helmet 15 includes the face guard 13 that is removably attached to a forward portion of the scanning helmet 15. The face guard 13 may be used by the player, when wearing the scanning helmet 15, to assist the player in determining a preferred helmet wearing position. Once the player positions the scanning helmet 15 such that a preferred helmet wearing position is achieved, the face guard 13 is removed, as exemplarily shown in
After the player P determines and indicates to an operator that the scanning helmet 15 is properly positioned on the player's head H, the operator conducts a first helmet scan of the player P and the scanning helmet 15 while the player P is wearing both the scanning hood 10 and the scanning helmet 15. The player P and helmet scan is taken by a scanning apparatus 22 utilizing one or more image sensors (e.g., cameras), lasers (e.g., LiDAR) or other scanning technologies (e.g., contact scanning, laser triangulation scanning or structured light scanning). In some embodiments, the scanning apparatus 22 is a single, hand-held unit, such as a personal computer, tablet or cell phone that an operator holds and moves around the player's head H and the scanning helmet 15 to capture images of both. In some embodiments, a plurality of scanning apparatuses 22 is arranged in a pre-determined pattern and orientation relative to the scanning subject, or player P. In some embodiments, photographs are taken of the player P wearing the scanning helmet 15 and used for reference to properly align a hood scan, as described below. Further, physical measurements of the player P wearing the scanning helmet 15 can be taken and used to properly align the hood scan. Regardless of whether a single scanning apparatus 22 or multiple apparatuses 22 are employed, a plurality of scanning images, or a substantially continuous moving set of images, can be captured and recorded. These images can then be “stitched” or electronically combined together in various ways to produce a single three-dimensional scan, or data file.
In some embodiments, the reference markers 21 on certain portions of the scanning hood 10 can be raised or recessed structures (e.g., dimples). The number of markers 21 on the scanning hood 10 is such that there are enough markers 21 to allow for the accurate creation of the three-dimensional model, but low enough to make processing of the model efficient. For example, four and twelve markers 21 per square inch may be used. A person skilled in the art recognizes that more or fewer markers 21 may be used to alter the processing times and the accuracy of the model.
The markers 21 on the scanning hood 10 contain unique portions 27 to enable the computerized modeling system to efficiently and accurately process the images or video. An example of such unique portions 27 is exemplarily shown in
A scanning apparatus 22, such as a camera, is then utilized to obtain either two-dimensional images or video of the scanning hood 10 from a number of different angles or points of view. The images or video are then provided to a computerized modeling system, which first roughly detects the edges of scanning hood 10 in each image or frame of the video. For example, Sobel edge detection or Canny edge detection may be used. The computerized modeling system may then remove parts of the images or frames of the video that are known to not be contained within the scanning hood 10. This reduces the amount of data that will need to be processed by the computerized modeling system in the following steps. In addition, the removal of the parts of the images or frames of the video that are known to not be contained within the scanning hood 10 reduces the chance of errors in the following steps, such as the correlating or matches of a reference marker 21 with the background of the image.
Next, the computerized modeling system processes each image or frame of video to detect the reference markers 21, which in some embodiments are the unique markers 27 on the scanning hood 10. After detecting the reference markers 21, the computerized modeling system correlates or matches as many reference markers 21 in each image to other reference markers 21 in other images or frames of the video. This reference marker 21 matching informs the computerized modeling system of the alignment or position of each image or frame of video. Once the alignment or position of each image or frame of video is known, mathematical algorithms are utilized to reconstruct a three-dimensional model of the player with the scanning hood 10. Typically, this three-dimensional model of the scanning hood 10 is represented in wire-frame form: a wire-frame model is a mathematical model in which points that are adjacent on a mathematical surface are connected by line segments. Illustrations of a wire-frame model for a player wearing a scanning hood 10 are shown in
Once the three-dimensional model of the player with the scanning hood 10 is created, the computerized modeling system determines the scaling factor of the model. This is possible because the size of the reference markers 21 is known and fixed. Thus, the computerized modeling system determines the scaling factor of the model by comparing the known size of the reference markers 21 to the size of the reference markers in the model. Once this scaling factor is determined, the model can be used to accurately represent the player P.
After the helmet scan, or player and helmet scan, is taken, an operator confirms that the helmet scan is of adequate quality based upon predetermined quality criteria, and/or a visual or manual inspection of the helmet scan. These scan quality criteria include scan continuity, the inclusion of wrinkles or other perturbations, and recognition and/or visibility of the reference markers 21 or player facial features. If the helmet scan quality is determined to be of inadequate quality, a new helmet scan is taken of the player P and the scanning helmet 15. If this second helmet scan quality is determined to satisfy the scan quality criteria and/or the visual or manual inspection, then this helmet scan is then saved to a local storage or uploaded to a remote storage or cloud storage device hosted by a separate entity and accessible to the operator. The helmet scan can be saved as a helmet scan data file, and the helmet scan data file can be saved and/or uploaded to a central server.
Following a successful helmet scan, the scanning helmet 15 is removed from the player's head H. The scanning helmet 15 is removed such that the reference markers 21 on the scanning hood 10 are not disturbed or displaced. While the player P is wearing the scanning hood 10, but not the scanning helmet 15, a hood, or a player and hood, scan is taken with the scanning apparatus 22. The hood scan can be taken by one or more scanning apparatuses 22 in a manner similar to the process described above for taking the helmet scan. Similar to the helmet scan, after the hood scan has been taken, the operator confirms that the hood scan satisfies the scan quality criteria, or is approved by a visual or manual inspection of the hood scan. The scan quality criteria include the scan continuity, the inclusion of wrinkles or other perturbations, and a recognition and visibility of the reference markers 21 and player facial features. If the hood scan quality is determined to be of inadequate quality, a new hood scan is taken. If this second hood scan quality is determined to satisfy the scan quality criteria and/or the visual or manual inspection, then this hood scan is then saved to a local storage or uploaded to a remote storage or cloud storage device hosted by a separate entity and accessible to the operator. The helmet scan can be saved as a helmet scan data file, and the helmet scan data file can be saved and/or uploaded to a central server.
The player P removes the scanning hood 10 from his or her head H after the hood scan is saved or uploaded. Following each of the helmet scan and the hood scan, the player P may be shown a resulting two-dimensional or three-dimensional image from each respective scan.
A method for acquiring, storing and processing a player's unique data, namely the player's anatomical features, continues with processing both the player and helmet scan or “helmet scan,” and the player and hood scan or “hood scan.” As exemplarily shown in
Following a confirmation of adequate helmet scan quality, the helmet scan is selected and aligned three-dimensionally within the three-dimensional software. In some embodiments, the helmet scan is aligned in three-dimensional space according to a pre-set template, which may be the helmet shell template. The proper alignment of the helmet scan may be made with reference to a predetermined set of coordinates or reference points, a helmet shape or the player's facial features (e.g., brow region, upper lip region, nose bridge or nose tip) within the helmet shell template, or using another method or reference system. In particular, the helmet scan can be aligned with one or more of the helmet shell size reference layers within the helmet shell template, or one or more features represented in the one or more of the helmet shell size reference layers within the helmet shell template. Such an alignment can be made along, or according to, multiple axes. A confirmation that the helmet scan is properly aligned in the three-dimensional software and/or the shell template is then made. Such a confirmation can include a visual and/or manual inspection of the alignment. When the helmet scan is determined to be improperly aligned in the three-dimensional software and/or with the helmet shell template, the helmet scan is realigned until the helmet scan is properly aligned in the three-dimensional software and/or with the helmet shell template.
Following a confirmation of adequate hood scan quality, the hood scan is selected and then aligned three-dimensionally within the three-dimensional software. The proper alignment of the hood scan may be made with reference to a predetermined set of coordinates, reference points, reference markers 21 and/or facial features within the properly-aligned helmet scan or using another method or reference. In some embodiments, the facial features in the hood scan, which may include the player's brow region, brow, nose bridge, nose tip or upper lip region, are aligned with a corresponding player facial feature in the properly-aligned helmet scan. Such an alignment can be made along multiple axes. The properly-aligned helmet scan, or reference markers 21 therefrom, may be simultaneously viewed from multiple perspectives when the hood scan, or reference markers 21 therefrom, is selected and viewed.
In some embodiments, the reference markers 21 and/or the nose region of the player are identified in the hood scan and used to properly align the hood scan in the three-dimensional software with respect to the properly-aligned helmet scan, reference markers 21 and/or the player's nose bridge, nose tip or brow in the helmet scan, or other reference means or markers from the properly-aligned helmet scan. A confirmation that the hood scan is properly aligned with respect to aspects of the properly-aligned helmet scan, the hood template or another pre-determined set of coordinates in the three-dimensional software is then made. Such a confirmation can include a visual and/or manual inspection of the alignment. When the hood scan is found to be improperly aligned with respect to the above-mentioned criteria, the hood scan is realigned until it is properly aligned in the software program.
The properly aligned hood scan may then be compared with known helmet shell size data, or to the properly aligned helmet scan, to check for certain relative tolerances and relationships. In some embodiments, the properly aligned hood scan is compared with the Minimum Certified Surface (MCS) layer in the helmet shell template corresponding to a given helmet shell size. The MCS is a reference surface defined by a collection of minimum distance values between an outer surface of the player's head H and a helmet shell. An internal padding assembly typically occupies the MCS when the internal padding assembly is installed in a shell of a protective sports helmet. Consistent with industry standards, every NOCSAE certified protective sports helmet has an MCS. Ideally, the player's head H should not penetrate or extend into the MCS when the player P wears the protective sports helmet. An MCS value, or set of values, may vary based on a given helmet shell location or padding location within the helmet shell. Data from the properly aligned hood scan and/or properly aligned helmet scan can be used to determine whether such an MCS is satisfied based on known measurements of a given helmet shell size. Further, the MCS layer of the helmet shell template, or a separate MCS template or data set, can instead, or additionally, be compared with customized insert files to determine satisfaction of MCS tolerances, as described below. If the MCS, or another tolerance measurement, is satisfied through the comparison of aligned hood scan data and the MCS layer of the helmet shell template for the selected shell size, it is determined that a customized helmet manufactured using the presently disclosed methods can be made for that player P using the given helmet shell size.
If, however, the MCS, or other tolerance measurement, is not satisfied through a comparison of aligned hood scan data and known measurements of a helmet shell size or the MCS layer of the helmet shell template for the shell size, it is determined that a bespoke helmet manufactured using the presently disclosed methods cannot be made for that player P using the given helmet shell size. In this scenario, the player or scan operator will then select a larger helmet shell size and perform a new helmet scan and hood scan using a scanning helmet corresponding to the larger helmet shell size. This selection process can continue until a helmet and hood scan are produced where data from the properly aligned hood scan satisfies the MCS layer of the helmet shell template, or other tolerance measurement, such that a comparison of aligned hood scan data and the MCS layer of the helmet shell template for the selected shell size allows a customized helmet manufactured using the presently disclosed methods to be made for that player using the given selected helmet shell size.
When the MCS, or other tolerance measurement, is not satisfied through a comparison of aligned hood scan data and the MCS layer of the helmet shell template for the selected shell size, or known measurements of a given helmet shell size, and it is determined that a customized helmet manufactured using acquired customized helmet data cannot be made for that player using the given helmet shell size, the scan operator may compare the aligned hood scan data to known measurements of a helmet shell larger than the selected helmet shell size. When such a larger helmet shell size is selected and the aligned hood scan data satisfies the MCS layer of the helmet shell template of the larger shell size or known data of the larger helmet shell size, a customized protective sports helmet can be manufactured using the larger shell size.
Additionally, at least a portion of the properly-aligned and MCS-verified hood scan may be inset by a pre-determined distance and/or a player-preferred distance, as is further described below, to create a compression fit when the helmet is worn on the head of the player. This results in a customized padding assembly slightly compressing to form an interference fit with the player's head H when the helmet is worn by the player P. Such alterations include changing the size, shape, orientation or number of customized pads used in the manufacturing of the customized helmet.
Following the selection of an appropriate helmet shell size for a given player's customized helmet data, insert files, or insert manufacturing files, are created in order to form a set of inserts for the formation of customized helmet pads 54 that form the customized internal padding assembly 4. The insert files are created using the acquired and processed unique player and helmet data acquired from the aligned helmet and hood scans, and may further be created using an insert layer of the helmet shell template. Boolean operations can be used to create the insert files, as will be described below. The insert files may also incorporate various additional factors, variables or considerations in addition to the player's unique data gathered from the aligned helmet and hood scans. For example, the insert files may be adjusted based on the helmet shell size selected.
In some embodiments, a degree of inward pressure against a player's head H is desired while the bespoke helmet is worn by the player P. The inward pressure may be created by the shape, size and/or orientation of one or more customized pads, an arrangement of multiple customized pads, the helmet shell, a spacing element disposed between the helmet shell and one or more of the customized pads, and/or other features of the bespoke helmet. According to some embodiments, the inward pressure is generated by expansive, or restoring, forces of one or more pads that are slightly compressed when the player P wears the helmet on his or her head H relative to the pads' relaxed state when the customized helmet is not worn by a player P. The existence or degree of inward pressure can be selected from a range of pre-set degrees, or can be specified by the manufacturer of the customized helmet along with input from the player P. In other words, the insert files can be designed to create inserts that form a customized padding assembly with non-compressed inner dimensions that are less than a volume occupied by the player's head H, and/or the player P wearing the scanning hood.
In some embodiments, the creation of the insert files accounts for such inwardly directed pressure applied by the internal padding assembly on the player's head H. The inward pressure can be created, or adjusted, by altering the acquired player data and/or helmet data and measurements. For example, an insert file is adjusted to create a dimensional inset in a customized internal pad manufactured using the insert file. The resulting dimensional inset may increase the customized pad's thickness at one or more locations or the pad's overall thickness. As a result, the customized helmet has customized internal pads that feature an inner surface that is dimensioned further from the inner surface of the helmet shell and thereby slightly compress to form an interference fit with the player's head H when the helmet is worn by the player P. Such alterations include changing the size, shape, orientation or number of customized pads used in the manufacturing of the bespoke helmet. Further, the insert files can additionally compensate for a thickness of the scanning hood by including an additional compensating dimensional inset, corresponding to the thickness of the scanning hood, to more accurately reflect the actual topography of the player's head H, rather than the scanning hood on the player's head H. These alteration factors may be applied to any of the helmet scan, hood scan, properly-aligned helmet scan, properly-aligned hood scan and insert files during the processing of the images that allow for the manufacture of the customized helmet.
In some embodiments, a three-dimensional blank insert is placed near, or on, the properly-aligned hood scan in the three-dimensional software. The three-dimensional blank insert may be included with the insert layer of the helmet shell template. Then, optionally, the properly-aligned hood scan is inset by a particular distance or degree, which may be specific for the creation of that particular customized pad. A Boolean operation, or intersection calculation, may then be performed between a surface of the three-dimensional blank insert and at least a portion of the aligned, or aligned and inset, hood scan. An insert file is then created, a surface of which reflects the player's head topography in the surface of the insert file.
In some embodiments, the creation of the insert file accounts for various player preferences regarding the fit of one or more padding elements. For example, if a player prefers a looser or tighter fitting crown pad, such a preference can be accommodated for in the making of the customized helmet with customized pads. The preference can be accommodated by altering the size, shape, orientation or number of the customized internal pads used in the manufacturing of the customized helmet. This preference factor may be applied to any of the helmet scan, hood scan, properly-aligned helmet scan, properly-aligned hood scan and insert file. Additionally, the insert files may be refined, smoothed or optimized manually, by software or by electronic computer-based tools based on a range of factors including, but not limited to, electronic errors, non-continuous surfaces, overlapping surfaces, meshing inconsistencies, meshing anomalies and/or meshing gaps. Such operations may be performed without substantially, or in any degree, altering a shape of any of the aforementioned scans or files, and merely may refine or optimize the electronic files in preparation for customized helmet manufacturing.
The customized internal padding assembly 4, as exemplarily shown in
The above steps substantially complete the method for acquiring, storing and processing a player's unique data and the processing of both the helmet scan and the hood scan.
The systems and methods of using the player's unique data to manufacture the customized helmet with a customized internal padding assembly that substantially corresponds to the player's unique data includes creating inserts 40 that are used to form the customized internal padding assembly. Inserts 40, created using the insert files, are best illustrated in
A subtractive manufacturing process includes machining and any number of machining tools known to those skilled in the art. Such machine tools comprise mills, lathes, saws, drills, bores and reamers, among many others, and operate using manual controls and/or Computer Numeric Controls (CNC). Such CNC machine tools incorporate Computer-Aided Manufacturing (CAM) controls and software to enable precise electronic control of the manufacturing process, and CAM cutting paths may be calculated, before subtractive manufacturing, based on the insert file. The subtractive manufacturing process creates the final insert 40 from a blank made of any number of polymers, metals or ceramics by removing material from the blank with one or more machine tools.
Following insert 40 creating using either the additive or subtractive process, the inserts 40 may be checked for adequate quality, continuity and other properties for use in the manufacturing of customized components for a customized protective sports helmet. Inserts 40 determined to be of adequate quality, continuity and/or other properties for use in the manufacture of a customized protective sports helmet pad are used in the creation of customized helmet pads.
The disclosure continues with the manufacture of customized protective helmet pads. An example of an apparatus for manufacturing bespoke helmet pads, as illustrated in
Prior to casting, a weight of the urethane casting material is verified based upon volume calculations derived from the Boolean operations and/or insert files, described above. Further, a ratio of isocyanate and resin may be verified for the customized pad, or customized part, being created. The ratio may be determined for a particular type of pad, such as a front pad, and/or may be determined for a particular player based on one or more of player preferences, player head topographical features, player history, player skill level and player position. It may be understood that various properties of a finished and cast customized pad, such as hardness and compression deflection ratings, may be altered by adjusting the aforementioned ratio of isocyanate and resin.
One or more inserts 40, created as described in the preceding sections, are placed into the internal cavity 44, and the insert 40 may be placed substantially within a portion of the internal cavity 44 formed in the lower section of the mold 36. A velcro panel, or a loop panel, may be affixed to a portion of the upper mold section 32. The loop panel may be affixed to the upper mold section 32 using adhesives, or any other mechanical attachment system.
A backing material 48, which in some embodiments is nubuck, may then be secured to the upper section of the mold 32 via a positioning apparatus, or a backing loop, adhesives, magnets, vacuum-forces or any other mechanical attachment system. The backing loop can be an embroidery loop, and the backing material 48 may be secured to the positioning apparatus using various mechanical fasteners. When employed, the positioning apparatus facilitates a consistent placement of the backing material 48 relative to the upper section of the mold 32. The backing material 48 may also be waterproof or water resistant. The positioning apparatus may attach to the upper section of the mold 32 by conventional fastening means, including mechanical fasteners, mechanical positioning devices, magnets and/or adhesives. When the positioning apparatus, including the attached backing material 48, is properly attached to the upper section of the mold 32, the backing material 48 is disposed on an underside of the upper section of the mold 32 when the upper section of the mold 32 is properly placed on the lower section of the mold 36. An electronic identification device, which may be a Radio Frequency Identification (RFID) device, may be attached to the backing material 48 and used to verify that the correct insert 40 is being used for the manufacturing of the correct customized pad for the correct player.
When the mold upper section 32 is properly placed on top of the mold lower section 36, a vent stem, configured as a threaded male member, may allow gasses to escape the internal cavity 44. The vent stem may be selectively opened to allow various flow rates when the threaded vent is opened. In some embodiments, the vent stem is placed into a receptacle in the upper mold section 32. Such a placement ensures the correct location of the threaded vent relative to the backing material. The vent stem may also be secured to the backing material 48. When forming certain customized pads, for example jaw pads, crown pads and rear pads, the vent is left in place when the customized pad is completed, and serves to aid in the attachment of the customized pad to the helmet shell. When forming other customized pads, for example occipital, front and side pads, all or a portion of the vent is removed from the customized pad when the customized pad is completed.
In some embodiments, the vent comprises a channel formed in one or more of the upper mold section 32 and the backing material 48, and gasses are selectively allowed to pass from the internal cavity 44 to the exterior of the top mold section via the channel. In a further embodiment, a grommet formed in the upper mold section 32 frictionally secures, and properly aligns, the vent stem relative to the upper mold section 32, internal cavity 44 and/or the backing material 48.
In some embodiments, a pre-formed insert, or a high-ratio internal insert, may be attached to the upper and/or lower mold sections 32, 36. The pre-formed internal insert may have a particular ratio of isocyanate to resin, and may have a relatively high ratio of isocyanate to resin relative to the urethane cast material used to form the customized pad. In some embodiments, a plug in the high-ratio internal insert mates with a grommet in the upper mold section 32 to thereby secure the high-ratio internal insert in place during the molding process. The urethane casting material may, wholly or partially, surround the high-ratio internal insert during the molding process such that the high-ratio internal insert becomes a portion of the completed customized pad. In some embodiments, a high-ratio internal insert may be used in the casting of a customized front pad, occipital pad and jaw pad.
A forming element, which may be formed from silicone, may be placed into the mold cavity 44 during molding. The forming element may be freely placed into the mold cavity 44, or may be affixed to one or more of the upper or lower mold sections 32, 36, high-ratio internal insert or insert 40, and may serve to create desired shapes, forms, tolerances and/or characteristics of the final customized pad. In some embodiments, the forming element creates a particular radius, or radii, on the customized pad, and the forming element may further be employed when forming a customized front pad and a customized occipital pad.
At least one badge which may include indicia such as a player's name, jersey number and/or signature, and/or a name, slogan or images of an entity such as a company, may be affixed to one of the completed customized pads. In particular, a player identification badge 41, as exemplarily shown in
A covering material 52 is heated for use in the casting process. The covering material 52 may include Ethylene-Vinyl Acetate (EVA) and/or may include expanded vinyl and Lycra (elastic polyurethane fabric) layers. The covering material 52 may form a complete or partial moisture and/or gas barrier. In some embodiments, the covering material 52 includes EVA in the form of a foam. Further, the EVA in the covering material 52 may represent closed cell foam and may thereby form the moisture barrier.
The covering material 52 may be heated in an oven in isolation, may be heated in the oven while attached to a covering material positioning apparatus, or may be heated in the over while attached to a portion of the lower mold section 36. The covering material positioning apparatus facilitates a consistent placement of the covering material 52 relative to the lower section of the mold 36. Upon the covering material 52 reaching a pre-set temperature, or a pre-set temperature range, the covering material 52 (optionally via the covering material positioning apparatus and/or a portion of the lower mold section 36) is attached to the lower section of the mold 36 by conventional fastening methods, including mechanical fasteners, mechanical positioning devices, magnets and/or adhesives. The pre-set temperature, or temperature range, may be a temperature, or temperature range, appropriate for covering material vacuum forming, such that the covering material will deform, or respond to, the vacuum-forming by a particular degree to adequately form to the insert 40 and lower mold section 36. When the covering material 52 is properly attached to the lower section of the mold 36, the covering material 52 is disposed over the insert 40, such that the insert 40 is disposed substantially between the covering material 52 and the lower section of the mold 36 within the internal cavity 44.
When the covering material 52 is properly attached to the lower section of the mold 36 and the covering material 52 is thus properly disposed over the insert 40 as described, a vacuum apparatus is operated and creates a partial or complete vacuum within the internal cavity 44 and vacuum-forms the covering material 52 to one or more contours of the insert 40 and/or the lower mold section 36. The vacuum apparatus may be in fluid communication with the internal cavity 44 through a vacuum aperture formed in the lower section 36 of the mold, and the vacuum apparatus may create the partial or complete vacuum within the internal cavity 44 by negatively pressurizing the internal cavity 44 relative to the exterior of the mold 28 via the vacuum aperture.
In some embodiments, the covering material 52 is vacuum-formed to an upper insert surface 50. In this process, the covering material 52 may form to, and adopt the shapes and contours of, the upper insert surface 50. A weight of the urethane casting material may be checked for accuracy at this stage.
After the covering material 52 has been vacuum-formed to a surface of the insert 40, or the upper insert surface 50, the covering material 52 may form a substantially concave surface within the lower section of the mold 36. Liquid, solid or semi-solid casting material, which may also be called urethane and/or padding material, is then poured into the substantially concave surface formed in the covering material 52. This process can be termed ‘casting.’
The casting material includes isocyanate and resin combined at a particular ratio. As described above, the ratio of isocyanate and resin may be determined for the customized pad being created. The ratio may be determined for a particular type of pad, such as a front pad or a jaw pad, and/or may be determined for a particular player based on one or more of player preferences, player head topographical features, player history, player skill level and player position.
The upper and lower mold sections 32, 36 are then brought substantially or wholly together, forming the cavity 44, and the poured casting material is allowed to cool, cure, solidify, and take the form of portions of the vacuum-formed covering material 52. In particular, a lower portion of the casting material, or urethane, may take the form of the vacuum-formed covering material 52, which had previously been vacuum-formed to the upper insert surface 50. Thus, contours and shapes of the upper insert surface 50 and lower mold section 36 are transferred to the vacuum-formed covering material 52 and then to the poured casting material. Further, upper and lateral portions of the casting material may take the form of a portion of the upper mold section 32, transferred to the casting material via the backing material 48. After the poured casting material cools and solidifies, the now-solidified casting material reflects the shapes and contours of the vacuum-formed covering material 52 and the upper insert surface 50, as well as the upper and lower sections of the mold 32, 36. Specifically, a lower surface of the solidified casting material, or an inner surface of the solidified casting material or customized pad, may reflect the shapes and contours of the vacuum-formed covering material 52 and the upper insert surface 50.
After the casting material is cast into the vacuum-formed covering material 52, pressure may be released from the mold cavity 44. This may be accomplished by puncturing a seal in the threaded vent, puncturing the backing material 48, opening a venting element built into the upper or lower mold sections 32, 36 or partially separating the upper and lower mold sections 32, 36.
Following the cooling and/or solidification of the casting material, the customized pad is extricated, or de-molded, from the now-separated upper and lower mold sections 32, 36. A sealant material may then be applied to one or more surfaces of the customized pad. In some embodiments, the sealant material is lycra (elastic polyurethane fiber), or elastane. In some embodiments, the sealant material is laminated on, or over, one or more surfaces of the customized pad. In some embodiments, edges of the customized pad are sealed with a silicone ring. In some embodiments, edges of the customized pad are molded with silicone, a sprayed or painted rubberized material or waterproof tape.
If excess, or undesirable, casting material is present on the de-molded customized pad, the excess casting material may be removed by die cutting, or other manual cutting or removal methods. The dies may include two-dimensional dies and/or three-dimensional dies. Once separated from the excess casting material, the customized pad may be checked for various properties, including density, compression deflection, size, weight, shape, consistency and color, among other possible properties. In some embodiments, in addition to or instead of individualized customized pad testing, test samples are cast and tested at various points to ensure the consistency and quality of the casting material. Acceptable ranges or threshold figures may be determined for each variable for which the customized pad, or test sample, is tested. If a given customized pad or test sample does not meet an acceptable range or threshold value for one or more properties, the customized is re-cast and again checked for the one or more properties. If the given customized pad meets the acceptable range or threshold value for the one or more properties, the customized pad is suitable for use in a customized helmet manufactured using acquired customized helmet data.
After one or more customized helmet pads 54 are formed by the above-described process, the one or more customized helmet pads 54 are then attached directly or indirectly to the interior surface of a helmet shell for use by the player. An example of a customized internal padding assembly 4 manufactured using the above-described methods and systems is exemplarily illustrated in
Fully Bespoke Helmet and System
In the fully bespoke helmet embodiment, the disclosed system and methods include a number of processes and sub-processes that are used to acquire and process data concerning the player's unique anatomical features and then use the processed data to manufacture a bespoke protective sports helmet where the helmet shell and the internal padding assembly are both purposely designed, configured and manufactured to match the anatomical features of the player's head. The internal padding assembly is purposely designed, configured and manufactured in the manner explained in the foregoing paragraphs of the Bespoke Helmet and System section, or in the below Partially Bespoke Helmet and System section. The fully bespoke helmet shell is designed based upon (i) the helmet and hood scans discussed in the foregoing paragraphs of the Bespoke Helmet and System section, and (ii) a combination of the player's playing style (including his/her tackling technique), the player's impact history, the player's skill level, the player's position(s) (e.g., quarterback, wide receiver, offensive line, linebacker, etc.), and the extent, if any, of the player's prior injuries.
With these considerations in mind, the fully bespoke helmet shell can designed to provide increased protection in a particular region(s) of the shell. This increased protection can be accomplished by: increasing the thickness of the desired shell region, adjusting the material properties of the desired shell region (e.g., increasing the stiffness of the rear region of the shell), or changing the configuration of the desired shell region including the shell corrugations in that region (e.g., increasing the dimensions of the corrugation in the rear shell region).
Partially Bespoke Helmet and System
Embodiments of the present disclosure also include processes and sub-processes used to acquire and process data concerning the player's unique anatomical features and subsequently use the processed data to design, select and optimize a padding assembly configured to substantially correspond to anatomical features of the player's head. In some embodiments, the internal padding assembly of a partially-customized helmet 1000, or a custom-selected internal padding assembly 1002, includes an arrangement of custom-selected pads 1004 selected from a large number of pre-manufactured pads.
As described in the above-section detailing acquisition of the player's anatomical features data, a process for creating the partially-customized helmet 1000 similarly includes gathering dimensional, topographical and preference data from the player. In particular, similar to the processes described above, the process for creating the partially-customized helmet 1000 may include i) placing the scanning hood 10 on, or over, the head H of the player P, ii) verifying that the scanning hood 10 is appropriately positioned and oriented on the player's head H, iii) selecting a scanning helmet 15 shell size, iv) placing the scanning helmet 15 over the player's head H while the player P is wearing the scanning hood 10, v) determining a preferred helmet wearing position, vi) obtaining a helmet scan using a scanning apparatus 22, vii) removing the scanning helmet 15 from the player's head H and viii) obtaining a hood scan using a scanning apparatus 22. However, it is to be understood that the process for creating the partially-customized helmet 1000 may include any and all steps, techniques, technologies, methods and devices, used in any order or combination, from the section detailing acquisition of the player's anatomical features data.
Further, the process for creating the partially-customized helmet 1000 may include all steps, techniques, technologies, templates, methods, and devices as described in the section detailing acquisition of the player's anatomical features data. In particular, the process may include ix) confirming adequate helmet scan quality, x) aligning the helmet scan within three dimensional software according to the helmet shell template, xi) confirming adequate hood scan quality, xii) aligning the hood scan relative to the aligned helmet scan or other reference points, xiii) verification of MCS satisfaction based on known measurements of a given helmet shell size, xiv) creating a dimensional inset in the aligned and MCS-verified hood scan, xv) accounting for player preferences, history, position, skill level or other factors in the aligned, inset, and MCS-verified hood scan and modifying the hood scan accordingly and xvi) comparing the aligned, inset, MCS-verified hood scan with one or more partially-customized pad selection layers in the helmet shell template.
The partially-customized pad selection layer may include three-dimensional models of a range of custom-selected pads 1004. The custom-selected pads 1004 are pre-formed, and include a wide range of physical characteristics. For example, the custom-selected pads 1004 include a variety of lengths, widths, heights, compression deflections, contours, concavities, angles, radii, attachment systems, colors and materials, as well as a range of isocyanate to resin ratios. As will be understood by one skilled in the art, upon a comparison of the aligned, inset, MCS-verified hood scan data with the one or more partially-customized pad selection layers in the helmet shell template, a custom-selected internal padding assembly 1002 may be selected for that player's partially-customized helmet 1000 that includes an arrangement of custom-selected pads 1004. The custom-selected pads 1004 may be selected based upon the aligned, inset and MC S-verified hood scan data, a dimensional fit or connection between a particular custom-selected pad 1004 and a helmet shell, and/or a dimensional fit or connection between custom-selected pads 1004.
The custom-selected internal padding assembly 1002, as exemplarily shown in
Further, although the use of a partially-customized pad selection layer within a helmet shell template is described, it is to be understood that any method of forming a partially-customized helmet 1000 using custom-selected pads 1004 selected from a large number of pre-manufactured pads based upon gathered player physical data is within the scope of this disclosure.
On-field results of monitored head impact exposures (HIE) collected by the proprietary technologies owned by the assignee of the present Application can be used to inform certain design parameters of the bespoke helmet discussed above. The monitored HIE results were obtained by the assignee's advanced wearable monitoring systems, that features an arrangement of impact monitoring sensors, disclosed in U.S. patent application Ser. No. 13/603,319 and U.S. Pat. Nos. 6,826,509, 7,526,389, 8,797,165 and 8,548,768, each of which including the content thereof are hereby incorporated by reference. For instance, a football player's skill or age level and playing position may, when compared to a larger database of similar players, indicate certain preferred helmet design characteristics. These characteristics may provide benefit to players based upon expected HIE levels at differing skill/age levels and/or on-field playing positions or groups of playing positions. Hypothetically, a college football quarterback may expect an elevated HIE metric of high-intensity impacts directed to the back of the head. The bespoke helmet, including the internal padding assembly, can be adjusted to provide greater protection levels accordingly.
Examples of using the HIE results to inform design parameters include using the impact data collected and stored in a database to create a position and/or skill level specific helmet that is designed based upon a generic data set based on skill level and position, but not influenced by a specific player's impact results and data. Another example of utilizing the HIE results includes using the HIE data collected from a specific player in combination with the broader data that has been collected and stored in the repository to create a fully personalized helmet. Another example of utilizing the HIE results involves installing sensor instrumentation in a player's helmet to enable further customization based on additional data that is collected after a pre-set amount of time or play. This instrumentation is included in the personalized helmet to further inform the data set and how to alter the inserts to provide a greater bespoke fit. These examples and the usage of HIE results applies to all three bespoke embodiments discussed above—the bespoke helmet and system, the fully bespoke helmet and system, and the partially bespoke helmet and system.
As is known in the data processing and communications arts, a general-purpose computer typically comprises a central processor or other processing device, an internal communication bus, various types of memory or storage media (RAM, ROM, EEPROM, cache memory, disk drives etc.) for code and data storage, and one or more network interface cards or ports for communication purposes. The software functionalities involve programming, including executable code as well as associated stored data. The software code is executable by the general-purpose computer. In operation, the code is stored within the general-purpose computer platform. At other times, however, the software may be stored at other locations and/or transported for loading into the appropriate general-purpose computer system.
A server, for example, includes a data communication interface for packet data communication. The server also includes a central processing unit (CPU), in the form of one or more processors, for executing program instructions. The server platform typically includes an internal communication bus, program storage and data storage for various data files to be processed and/or communicated by the server, although the server often receives programming and data via network communications. The hardware elements, operating systems and programming languages of such servers are conventional in nature, and it is presumed that those skilled in the art are adequately familiar therewith. The server functions may be implemented in a distributed fashion on a number of similar platforms, to distribute the processing load.
Hence, aspects of the disclosed methods and systems outlined above may be embodied in programming. Program aspects of the technology may be thought of as “products” or “articles of manufacture” typically in the form of executable code and/or associated data that is carried on or embodied in a type of machine readable medium. “Storage” type media include any or all of the tangible memory of the computers, processors or the like, or associated modules thereof, such as various semiconductor memories, tape drives, disk drives and the like, which may provide non-transitory storage at any time for the software programming. All or portions of the software may at times be communicated through the Internet or various other telecommunication networks. Thus, another type of media that may bear the software elements includes optical, electrical and electromagnetic waves, such as used across physical interfaces between local devices, through wired and optical landline networks and over various air-links. The physical elements that carry such waves, such as wired or wireless links, optical links or the like, also may be considered as media bearing the software. As used herein, unless restricted to non-transitory, tangible “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution.
A machine readable medium may take many forms, including but not limited to, a tangible storage medium, a carrier wave medium or physical transmission medium. Non-volatile storage media include, for example, optical or magnetic disks, such as any of the storage devices in any computer(s) or the like, such as may be used to implement the disclosed methods and systems. Volatile storage media include dynamic memory, such as main memory of such a computer platform. Tangible transmission media include coaxial cables, copper wire and fiber optics, including the wires that comprise a bus within a computer system. Carrier-wave transmission media can take the form of electric or electromagnetic signals, or acoustic or light waves such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media therefore include for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards, paper tape, any other physical storage medium with patterns of holes, a RAM, a PROM and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer can read programming code and/or data. Many of these forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to a processor for execution.
While the foregoing has described what are considered to be the best mode and/or other examples, it is understood that various modifications may be made therein and that the subject matter disclosed herein may be implemented in various forms and examples, and that the teachings may be applied in numerous applications, only some of which have been described herein. It is intended by the following claims to claim any and all applications, modifications and variations that fall within the true scope of the present teachings.
Other implementations are also contemplated.
This application claims priority to, under 35 U.S.C. § 119, U.S. Provisional Application No. 62/364,629 filed on Jul. 20, 2016, the entire content of which is hereby incorporated by reference in its entirety for all purposes.
