An area of ongoing research and development is systems and methods to provide for accurate scoring of athletic events. More recently instant replay has been instituted in various sports to allow officials to review plays and calls made by the officials. However, in many sports, human scoring and officiating still produces a controversial margin of error. With athletes pushing the envelope of human performance, it becomes more difficult for humans to officiate and score athletic events. There therefore exists the need for systems and methods that further remove officiating and scoring duties away from humans in athletic events.
The foregoing examples of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the relevant art will become apparent to those of skill in the art upon reading the specification and studying of the drawings.
The following implementations and aspects thereof are described and illustrated in conjunction with systems, tools, and methods that are meant to be exemplary and illustrative, not necessarily limiting in scope. In various implementations one or more of the above-described problems have been addressed, while other implementations are directed to other improvements.
Various implementations include systems and methods for scoring an athletic event based on changes in impedance in impedance-based impact measuring sporting equipment as a result of impacts delivered during the athletic event. In various implementations, a conductive material of a plurality of separate conductive materials are coupled to a first participant, the conductive material configured to move when the first participant delivers an impact to a second participant. Further, in various implementation, an impedance-based impact sensing mechanism including an impedance changing mechanism that changes impedance as the conductive material is moved towards and away from the impedance changing mechanism as the first participant delivers the impact. In various implementations, an impedance-based impact measuring scoring system determines that the impact occurred based on a change in impedance in the impedance changing mechanism.
These and other advantages will become apparent to those skilled in the relevant art upon a reading of the following descriptions and a study of the several examples of the drawings.
The impedance-based impact measuring sporting equipment 104 and the impedance-based impact measuring scoring system 106 are coupled to each other through the computer-readable medium 102. As used in this paper, a “computer-readable medium” is intended to include all mediums that are statutory (e.g., in the United States, under 35 U.S.C. 101), and to specifically exclude all mediums that are non-statutory in nature to the extent that the exclusion is necessary for a claim that includes the computer-readable medium to be valid. Known statutory computer-readable mediums include hardware (e.g., registers, random access memory (RAM), non-volatile (NV) storage, to name a few), but may or may not be limited to hardware.
The computer-readable medium 102 is intended to represent a variety of potentially applicable technologies. For example, the computer-readable medium 102 can be used to fonn a network or part of a network. Where two components are co-located on a device, the computer-readable medium 102 can include a bus or other data conduit or plane. Where a first component is co-located on one device and a second component is located on a different device, the computer-readable medium 102 can include a wireless or wired back-end network or LAN. The computer-readable medium 102 can also encompass a relevant portion of a WAN or other network, if applicable.
The computer-readable medium 102, the impedance-based impact measuring scoring system 106 and other applicable systems, or devices described in this paper can be implemented as a computer system, a plurality of computer systems, or parts of a computer system or a plurality of computer systems. A computer system, as used in this paper, is intended to be construed broadly. In general, a computer system will include a processor, memory, non-volatile storage, and an interface. A typical computer system will usually include at least a processor, memory, and a device (e.g., a bus) coupling the memory to the processor. The processor can be, for example, a general-purpose central processing unit (CPU), such as a microprocessor, or a special-purpose processor, such as a microcontroller.
The memory can include, by way of example but not limitation, random access memory (RAM), such as dynamic RAM (DRAM) and static RAM (SRAM). The memory can be local, remote, or distributed. The bus can also couple the processor to non-volatile storage. The non-volatile storage is often a magnetic floppy or hard disk, a magnetic-optical disk, an optical disk, a read-only memory (ROM), such as a CD-ROM, EPROM, or EEPROM, a magnetic or optical card, or another form of storage for large amounts of data. Some of this data is often written, by a direct memory access process, into memory during execution of software on the computer system. The non-volatile storage can be local, remote, or distributed. The non-volatile storage is optional because systems can be created with all applicable data available in memory.
Software is typically stored in the non-volatile storage. Indeed, for large programs, it may not even be possible to store the entire program in the memory. Nevertheless, it should be understood that for software to run, if necessary, it is moved to a computer-readable location appropriate for processing, and for illustrative purposes, that location is referred to as the memory in this paper. Even when software is moved to the memory for execution, the processor will typically make use of hardware registers to store values associated with the software, and local cache that, ideally, serves to speed up execution. As used herein, a software program is assumed to be stored at an applicable known or convenient location (from non-volatile storage to hardware registers) when the software program is referred to as “implemented in a computer-readable storage medium.” A processor is considered to be “configured to execute a program” when at least one value associated with the program is stored in a register readable by the processor.
In one example of operation, a computer system can be controlled by operating system software, which is a software program that includes a file management system, such as a disk operating system. One example of operating system software with associated file management system software is the family of operating systems known as Windows® from Microsoft Corporation of Redmond, Washington, and their associated file management systems. Another example of operating system software with its associated file management system software is the Linux operating system and its associated file management system. The file management system is typically stored in the non-volatile storage and causes the processor to execute the various acts required by the operating system to input and output data and to store data in the memory, including storing files on the non-volatile storage.
The bus can also couple the processor to the interface. The interface can include one or more input and/or output (I/O) devices. The I/O devices can include, by way of example but not limitation, a keyboard, a mouse or other pointing device, disk drives, printers, a scanner, and other I/O devices, including a display device. The display device can include, by way of example but not limitation, a cathode ray tube (CRT), liquid crystal display (LCD), or some other applicable known or convenient display device. The interface can include one or more of a modem or network interface. It will be appreciated that a modem or network interface can be considered to be part of the computer system. The interface can include an analog modem, isdn modem, cable modem, token ring interface, satellite transmission interface (e.g. “direct PC”), or other interfaces for coupling a computer system to other computer systems. Interfaces enable computer systems and other devices to be coupled together in a network.
The computer systems can be compatible with or implemented as part of or through a cloud-based computing system. As used in this paper, a cloud-based computing system is a system that provides virtualized computing resources, software and/or information to client devices. The computing resources, software and/or information can be virtualized by maintaining centralized services and resources that the edge devices can access over a communication interface, such as a network. “Cloud” may be a marketing term and for the purposes of this paper can include any of the networks described herein. The cloud-based computing system can involve a subscription for services or use a utility pricing model. Participants can access the protocols of the cloud-based computing system through a web browser or other container application located on their client device.
A computer system can be implemented as an engine, as part of an engine, or through multiple engines. As used in this paper, an engine includes at least two components: 1) a dedicated or shared processor and 2) hardware, finnware, and/or software modules that are executed by the processor. Depending upon implementation-specific or other considerations, an engine can be centralized or its functionality distributed. An engine can include special purpose hardware, firmware, or software embodied in a computer-readable medium for execution by the processor. The processor transforms data into new data using implemented data structures and methods, such as is described with reference to the FIGURES in this paper.
The engines described in this paper, or the engines through which the systems and devices described in this paper can be implemented, can be cloud-based engines. As used in this paper, a cloud-based engine is an engine that can run applications and/or functionalities using a cloud-based computing system. All or portions of the applications and/or functionalities can be distributed across multiple computing devices, and need not be restricted to only one computing device. In some embodiments, the cloud-based engines can execute functionalities and/or modules that end users access through a web browser or container application without having the functionalities and/or modules installed locally on the end-users' computing devices.
As used in this paper, datastores are intended to include repositories having any applicable organization of data, including tables, comma-separated values (CSV) files, traditional databases (e.g., SQL), or other applicable known or convenient organizational formats. Datastores can be implemented, for example, as software embodied in a physical computer-readable medium on a general- or specific-purpose machine, in firmware, in hardware, in a combination thereof, or in an applicable known or convenient device or system. Datastore-associated components, such as database interfaces, can be considered “part of” a datastore, part of some other system component, or a combination thereof, though the physical location and other characteristics of datastore-associated components is not critical for an understanding of the techniques described in this paper.
Datastores can include data structures. As used in this paper, a data structure is associated with a particular way of storing and organizing data in a computer so that it can be used efficiently within a given context. Data structures are generally based on the ability of a computer to fetch and store data at any place in its memory, specified by an address, a bit string that can be itself stored in memory and manipulated by the program. Thus, some data structures are based on computing the addresses of data items with arithmetic operations; while other data structures are based on storing addresses of data items within the structure itself. Many data structures use both principles, sometimes combined in non-trivial ways. The implementation of a data structure usually entails writing a set of procedures that create and manipulate instances of that structure. The datastores, described in this paper, can be cloud-based datastores. A cloud-based datastore is a datastore that is compatible with cloud-based computing systems and engines.
In a specific implementation, the impedance-based impact measuring sporting equipment 104 functions to detect characteristics associated with an impact. In detecting characteristics associated with an impact, the impedance-based impact measuring sporting equipment can include one or a plurality of sensors used in detecting characteristics associated with an impact. Sensors included as part of the impedance-based impact measuring sporting equipment 104 can include any combination of impedance based impact sensing mechanisms, gyroscopes, and/or inertial measurement units (hereinafter referred to as IMUs). Depending upon implementation-specific or other considerations, sensors included as part of the impedance-based impact measuring sporting equipment 104 can be used to measure changes in rotation and location of a participant in an athletic event. Changes in rotation and location, as measured by sensors included as part of the impedance-based impact measuring sporting equipment 104 can be used to measure impacts or magnitudes of forces of impacts, and/or score an athletic event. Further depending upon implementation-specific or other considerations, sensors included as part of the impedance-based impact measuring sporting equipment 104 can be arranged in a sensor matrix.
In a specific implementation, the impedance-based impact measuring sporting equipment 104 includes an outer layer of a synthetic elastomeric polymer. Sensors can be imbedded in the impedance-based impact measuring sporting equipment. Depending upon implementation-specific or other considerations, in manufacturing the impedance-based impact measuring sporting equipment, sensors can be embedded into a synthetic elastomeric polymer layer in a gel foam. In operation of the impedance-based impact measuring sporting equipment 104, an impact delivered to the impedance-based impact measuring sporting equipment 104 causes the synthetic elastomeric polymer to harden, thereby dispersing energy delivered through the impact across an outer surface or a portion of an outer surface of the impedance-based impact measuring sporting equipment 104.
In a specific implementation, the impedance-based impact measuring sporting equipment 104 includes one or a plurality of impedance-based impact sensing mechanisms that function to detect an impact and, e.g., a magnitude of a force of the impact. Depending upon implementation-specific or other considerations, the impedance-based impact measuring sporting equipment 104 can include a set of separate impedance-based impact sensing mechanisms positioned on various portions of a body of a participant using the impedance-based impact measuring sporting equipment 104, or on applicable inanimate objects. In positioning a set of separate impedance-based impact sensing mechanisms on a participant, a portion of the body of the participant of the impedance-based impact measuring sporting equipment 104 where impact occurs can be detected with accuracy sufficient to make the determination useful when scoring an athletic event, or for other applicable purposes where determining the location of a strike is useful.
In a specific implementation, an impedance-based impact sensing mechanism included as part of the impedance-based impact measuring sporting equipment 104 includes an impedance changing mechanism that changes impedance when a conductive element is moved relative to the impedance changing mechanism and/or when the conductive element comes into contact with the impedance changing mechanism. An impedance changing mechanism can include conductive coils that extend over an area or part of an area of the impedance-based impact sensing mechanism. A regulated AC can be passed through conductive coils that form part of an impedance changing mechanism to form a magnetic field. As a result, when a conductive material moves towards or away from conductive coils of an impedance charging mechanism, currents of varying sizes, e.g. “eddy currents”, are induced in the conductive coils that flow opposite the direction that the regulated AC passes through the conductive coils. Currents of varying sizes, induced in an impedance changing mechanism as a conductive material moves towards and away from the impedance changing mechanism, produce counter forces against an original current, e.g. regulated AC, passed through the impedance changing mechanism. As a result, impedance characteristics of an impedance changing mechanism change, e.g. lead to an increased impedance of the impedance changing mechanism, as a conductive material moves towards and away from the impedance changing mechanism.
In a specific implementation, when a metallic material worn by the striker or striking object approaches an electrically conductive coil with a reference inductance that is included as part of an impedance changing mechanism included as part of the impedance-based impact measuring sporting equipment. The approaching metal changes the inductive value of the coil due to Eddy current effect. This property can be used to identify the source of the strike which then can be used to qualify an impact of the strike.
In a specific implementation, an impedance-based impact sensing mechanisms included as part of the impedance-based impact measuring sporting equipment 104 includes or is coupled to a digital converter and a data processing system, such as a microprocessor. As a conductive material moves towards an impedance changing mechanism of an impedance-based impact sensing mechanism included as part of the impedance-based impact measuring sporting equipment 104, impedance characteristics of the impedance changing mechanism change. A digital converter included as part of or coupled to the impedance-based impact sensing mechanism generates signals based on changes in impedance in the impedance changing mechanism that can be processed by the data processing system part of or coupled to the impedance-based impact sensing mechanism. Signals generated and processed based on changes in impedance in the impedance changing mechanism can be used to determine impact to an impedance-based impact sensing mechanism of the impedance-based impact measuring sporting equipment 104 and a magnitude of a force of the impact to the impedance-based impact sensing mechanism.
In a specific implementation, the impedance-based impact measuring sporting equipment 104 includes a plurality of separate impedance changing mechanisms that have different impedance characteristics. In having different impedance characteristics, separate impedance changing mechanisms of the impact measuring sporting equipment can be distinguished from each other using impedance and changing impedance within the separate impedance changing mechanisms. Depending upon implementation-specific or other considerations, in having different impedance characteristics, the separate impedance changing mechanisms can change impedance at different rates when a conductive material is moved towards and away from each separate impedance changing mechanism at the same rate. Further depending upon implementation-specific or other considerations, in having different impedance characteristics, the separate impedance changing mechanisms can have different native impedances, a native impedance, as used in this paper, being an impedance of an impedance changing mechanism when a specific current is run through the impedance changing mechanism without the influence of a conductive material moved in proximity to the impedance changing mechanism. Different impedance characteristics of separate impedance changing mechanisms can be achieved by designing impedance changing mechanisms according to applicable techniques for creating different impedance characteristics in separate impedance changing mechanisms, such as including varying numbers of coils or coils of varying sizes of a conductive material in separate impedance changing mechanisms. In creating impedance-based impact sensing mechanisms that have different impedance characteristics, different parts of the body of a second participant or an applicable inanimate object receiving an impact of a first participant using the impedance-based impact measuring sporting equipment 104 can be detected. For example, based on different impedance characteristics of impedance-based impact sensing mechanisms of the impedance-based impact measuring sporting equipment 104 can be used to determine whether an impact is delivered by a first participant to the chest or the arm of a second participant.
In a specific implementation, the impedance-based impact measuring sporting equipment 104 includes a conductive material worn by a first participant delivering an impact to a second participant (or inanimate object). For example, the impedance-based impact measuring sporting equipment 104 can include a conductive material that is positioned on a hand or foot (or other part of the body, such as the elbow, shin, knee, etc.; or on a portion of a weapon) of a first participant using the impedance-based impact measuring sporting equipment 104 to allow an impact delivered against a second participant using of the impedance-based impact measuring sporting equipment 104 to be detected and characteristics, such as the magnitude of the force of the impact, to be determined. The conductive material can be placed in sporting equipment and apparel such as boxing gloves, MMA gloves, gloves, socks, sneakers, shoes, mittens, shirts, pants, shorts, elbow guards, helmets, shin guards, knee pads, striking garments, striking apparel, striking equipment, swords, weapons, and combinations thereof.
In a specific implementation, the impedance-based impact measuring sporting equipment 104 includes separate conductive materials that change impedance differently in impedance-based input sensing mechanisms of a participant wearing the impedance-based input sensing mechanisms. In changing impedances in impedance-based sensing mechanisms differently, separate conductive materials in the impedance-based impact measuring sporting equipment 104, can be of varying sizes or of varying materials. Specific conductive materials in the impedance-based impact measuring sporting equipment 104 can be of varying sizes or varying materials according to a position of specific conductive materials on a first participant using the impedance-based impact measuring sporting equipment 104 to deliver an impact to a second participant (or inanimate object) of the impedance-based impact measuring sporting equipment 104. For example, a conductive material on the foot of a first participant of the impedance-based impact measuring sporting equipment can be of a different size of a conductive material on a hand of the first participant, allowing an impact delivered by the foot of the first participant to be differentiated and subsequently determined from an impact delivered by the hand of the first participant.
In a specific implementation, the impedance-based impact measuring scoring system 106 functions to score, at least in part, an athletic event in which the impedance-based measuring sporting equipment 104 is used based on changing impedances of impedance changing mechanisms as a result of impact. In scoring, at least in part, an athletic event, depending upon implementation-specific or other considerations, the impedance-based impact measuring scoring system 106 determines a magnitude of a force of an impact to the impedance-based impact measuring sporting equipment 104 using a change of impedance in an impedance changing mechanism. Further depending upon implementation-specific or other considerations, in scoring, at least in part, an athletic event, the impedance-based impact measuring scoring system 106 can determine a portion of a second participant using the impedance-based impact measuring sporting equipment 104 to which impact is delivered using a change in impedance in an impedance changing mechanism. Depending upon implementation-specific or other considerations, in scoring, at least in part, an athletic event, the impedance-based impact measuring scoring system 106 can determine a portion of a first participant using impedance-based impact measuring sporting equipment 104 that impacts a second participant using impedance-based impact measuring sporting equipment 104 utilizing a change in impedance in an impedance changing mechanism. Further, in scoring, at least in part, an athletic event, depending upon implementation-specific or other considerations, the impedance-based impact measuring scoring system 106 can score the athletic event based on a magnitude of a force of a delivered impact, a portion of a second participant to which the impact is delivered, or a portion of a first participant that delivers the impact to the second participant.
In the example system shown in
In a specific implementation, the impact location determination system 110 functions to determine a portion of a second participant (or inanimate object) of the impedance-based impact measuring sporting equipment 104 at which an impact occurs. In determining a portion of a second participant of the impedance-based impact measuring sporting equipment 104 at which an impact occurs, the impact location determination system 110 can determine the portion of the second participant based on impedance characteristics specific to an impedance changing mechanism positioned on the body of the second participant. For example, the impact location determination system 110 can determine that an impact occurs in the chest of a second participant using impedance-based impact measuring sporting equipment 104 based on impedance characteristics of specific impedance changing mechanisms included as part of the impedance-based impact measuring sporting equipment 104. Depending upon implementation-specific or other considerations, the impact location determination system 110 can determine a specific impedance changing mechanism on a second participant based on rates at which impedance in the impedance changing mechanisms changes when a conductive material is moved towards and away from the impedance changing mechanism. Further depending upon implementation-specific or other considerations, the impact location determination system 110 can determine a specific impedance changing mechanism based on a native impedance of the specific changing mechanism included as part of the impedance-based impact measuring sporting equipment 104.
In a specific implementation, the impact delivery determination system 112 functions to determine a portion of a first participant using the impedance-based impact measuring sporting equipment 104 that delivers an impact to a second participant using the impedance-based impact measuring sporting equipment 104. For example, the impact delivery determination system 112 can determine that an impact is delivered by a foot or a hand of a first participant. In determining a portion of a first participant that delivers an impact, the impact delivery determination system 112 can use impact delivery characteristics data of a first participant using the impedance-based impact measuring sporting equipment 104. Impact delivery characteristics data of a first participant using the impedance-based impact measuring sporting equipment 104 can specify a rate at which impedance changes in impedance changing mechanisms as a result of conductive materials positioned at different position on a first participant being moved towards and away from the impedance changing mechanisms. Specifically, impedance delivery characteristics data are different for conductive materials of different sizes or materials that are positioned at different portion of a participant, e.g. a foot or a hand of the participant. Using a rate at which impedance changes in an impedance changing mechanism of a first participant using the impedance-based impact measuring sporting equipment 104 as a result of an impact to the impedance changing mechanism, and impact delivery characteristics, the impact delivery determination system 112 can determine a portion of a first participant that delivers the impact to a second participant. For example, the impact delivery determination system 112 can determine, based on the rate at which impedance changes in an impedance changing mechanism and impact delivery characteristics, that a foot of a first participant delivered impact to a second participant using the impedance-based impact measuring sporting equipment 104.
In a specific implementation, the scoring system 114 functions to score an athletic event in response to impacts received and delivered by wearers of the impedance-based impact measuring sporting equipment. For example, the scoring system 114 can score an athletic event based on where an impact is received, a magnitude of a force of the impact, and/or a portion of a first participant that delivers the impact. Further, the scoring system 114 can score an athletic event based on impact scoring data for an athletic event. Impact scoring data for an athletic event can specify how to score, e.g. a number of points to award a first participant, based on where an impact is delivered, a magnitude of a force of the impact, a portion of a user that delivers the impact, or other discernible factors.
In a specific implementation, the scoring system 114 can score an athletic event based on impact scoring data and a magnitude of a force of a delivered impact, as determined by the impact location determination system 108. Specifically, impact scoring data can specify to award a specific number of points based on a magnitude of a force of a delivered impact. As a result, the scoring system 114 can award a number of points as specified by impact scoring data to a first participant who delivers an impact based on a magnitude of a force of the impact, as determined by the impact force determination system 108.
In a specific implementation, the scoring system 114 can score an athletic event based on impact scoring data and a portion of a second participant to which an impact is delivered, as determined by the impact location determination system 110. For example, impact scoring data can specify to award a specific number of points based on a portion of a second participant to which an impact is delivered, e.g. award more points if an impact is delivered to a chest of a second participant as opposed to a leg. As a result, the scoring system 114 can award a number of points as specified by the impact scoring data to a first participant who delivers an impact based on a portion of a second participant to which the impact is delivered, as determined by the impact location determination system 110.
In a specific implementation, the scoring system 114 can score an athletic event based on impact scoring data and a portion of a first participant that delivers an impact to a second participant, as determined by the impact delivery determination system 112. For example, impact scoring data can specify to award a specific number of points based on a portion of a first participant that delivers an impact to a second participant, e.g. award more points if an impact is delivered by the foot of a first participant as opposed to a hand of the first participant. As a result, the scoring system 114 can award a number of points as specified by the impact scoring data to a first participant who delivers an impact based on a portion of the first participant that delivers the impact to a second participant, as determined by the impact delivery determination system 112.

Further depending upon implementation-specific or other considerations, a signal received fonn an impedance-based impact sensing mechanism by the impedance changing rate determination engine 208 includes a current through an impedance changing mechanism or a voltage across the impedance changing mechanism as an impedance of the impedance changing mechanism changes over a specific amount of time. The impedance changing rate determination engine 208 can determine impedance change rates of an impedance changing mechanism based on a signal received from a digital converter that is part of or coupled to an impedance-based impact sensing mechanism that includes the impedance changing mechanism. Depending upon implementation-specific or other considerations, a signal received from a digital converter by the impedance changing rate determination engine 208 includes impedances of an impedance changing mechanism over a specific amount of time.

In a specific implementation, the impedance changing rate determination engine 208 functions to determine impedance changing rates of an impedance changing mechanism based on determined impedances of the impedance changing mechanism over a specific period of time. For example, the impedance changing rate determination engine 208 can determine a first impedance at a first specific time in a specific period of time and a second impedance at a second specific time in the specific period of time after the first specific time to determine an impedance changing rate of the impedance changing mechanism. Depending upon implementation-specific or other considerations, an impedance changing rate of an impedance changing mechanism, as determined by the impedance changing rate determination engine 208 varies over a specific period of time.
In a specific implementation, the impedance changing rate datastore 210 functions to store impedance changing rate data. Impedance changing rate data stored in the impedance changing rate datastore 210 can include a specific force that is delivered to a specific impedance changing mechanism that corresponds to a specific rate at which impedance changes in the specific impedance changing mechanism. Impedance changing rate data stored in the impedance changing rate datastore 210 can be specific to impedance changing mechanisms included in the impedance-based impact measuring sporting equipment 204. For example, a first impedance changing mechanism can change impedance at a different rate from a second impedance changing mechanism, as reflected by impedance changing rate data stored in the impedance changing rate datastore 210.
In a specific implementation, the impact force determination engine 212 functions to determine a magnitude of a force of an impact delivered to an impedance-based impact measuring sporting equipment 204. The impact force determination engine 212 can determine a magnitude of a force delivered to impedance-based impact measuring sporting equipment 204 based on an impedance changing rates of an impedance changing mechanism, as determined by the impedance changing rate determination engine 208.
