Definitions

  • the invention relates to a multi-component system that actively monitors a physiological parameter of numerous players engaged in a sporting activity.
  • the system includes reporting units that provide for the transmission of each player's measured physiological data to a controller for calculation of the parameter and recordation of the results. Since most contact sports involve multi-player teams, the system can simultaneously measure, record and transmit data on the physiological parameter(s) for all players on the team throughout the course of play, including a game or practice.
  • Brain injury following impact occurs at the tissue and cellular level, and is both complex and not fully understood. Increased brain tissue strain, pressure waves, and pressure gradients within the skull have been linked with specific brain injury mechanisms. Linear and rotational head acceleration are input conditions during an impact. Both direct and inertial (i.e. whiplash) loading of the head result in linear and rotational head acceleration. Head acceleration induces strain patterns in brain tissue, which may cause injury. There is significant controversy regarding what biomechanical information is required to predict the likelihood and severity of MTBI. Direct measurement of brain dynamics during impact is extremely difficult in humans. [0010] Head acceleration, on the other hand, can be more readily measured; its relationship to severe brain injury has been postulated and tested for more than 50 years.
  • the present invention provides a multi-component system that actively monitors at least one physiological parameter of players engaged in a sporting activity.
  • the system includes reporting units with a telemetry element that provide for the transmission of each player's physiological parameter data to a controller for calculation, recordation and/or storage.
  • the reporting unit can be installed with each player's protective equipment. Since most contact sports involve multi-player teams, the system simultaneously measures, records and transmits the data on the physiological parameter(s) for all players on the team having a reporting unit throughout the course of play, including a game or practice.
  • the system is especially well suited for helmeted team sports where players are susceptible to head impacts and injuries; for example, football, hockey, and lacrosse. Since the system can be employed with every member of the team, the system simultaneously measures, transmits and/or records impact physiological data from each player throughout the course of the practice or game.
  • the system actively measures and calculates the acceleration of a body part (e.g. the head) of players while engaged in physical activity, such as during play of a contact sport.
  • a system controller transmits a signal to a signaling device to notify sideline personnel that a player(s) has experienced an elevated body part acceleration.
  • a system database stores the calculated body part acceleration for each player.
  • the system actively measures and calculates each player's body surface temperature during play.
  • the system controller transmits a signal to the signaling device to notify sideline personnel that a player(s) has experienced a significant body temperature increase.
  • the system actively measures and calculates the acceleration of each player's body part and the player's temperature during play.
  • the system can actively monitor multiple physiological parameters for each of the many players engaged in physical activity.

  • Figs. 1 and 2 depict a multi -component system 10 for actively monitoring a physiological parameter of numerous players engaged in a sporting activity, wherein the players' data is transmitted to a controller for monitoring and recordation.
  • the system 10 is configured to measure and calculate the acceleration of a body part (e.g., the head) of players while engaged in physical activity, such as during play of a contact sport.
  • the system 10 is designed to measure and calculate each player's body temperature during play.

  • the system 10 Since most contact sports involve multi-player teams, the system 10 simultaneously measures, records and transmits the data on the physiological parameter(s) for all players on the team throughout the course of play, including a game or practice.
  • the system 10 is especially well suited for helmeted team sports where players are susceptible to head impacts and injuries; for example, football, hockey, and lacrosse. Therefore, the system 10 represents a platform for actively monitoring the physiological parameters of players engaged in sporting activities. It is within the scope of the invention for the system 10 to be configured to monitor a physiological parameter of a smaller number of players, meaning not all players engaged in the physical activity.
  • the system 10 is generally comprised of multiple reporting units 20, a controller unit 40, a signaling device 60, a database 80, and software 90 that enables the various components of the system 10 to communicate and interact. While the system 10 is described below in the context of a helmeted team sport, the system 10 can be utilized in connection with other sporting activities that do not require a helmet, such as soccer or rugby. Consequently, the system 10 can be configured for use with other protective gear, such as a head band, leg guard, or shoulder pad. Because a football team includes numerous players, in some cases exceeding one hundred players, each player has a recording unit 20 that communicates with the controller 40. Therefore, the recording units 20 continuously and collectively measure and transmit physiological data to the controller for monitoring of the players. While a significant portion of the parameter measurement and monitoring occurs during the course of play, the system 10 continues to measure relevant physiological parameters, such as the players' body temperature, when players are at a reduced activity level on the sideline.
  • relevant physiological parameters such as the players' body temperature
  • the reporting unit 20 automatically and continuously measures and records the player's physiological parameters and transmits data regarding the parameter to the controller 40.

  • the control unit 24 can include a signal conditioner 24a, a filter 24b, a microcontroller 24c (or microprocessor), a telemetry element 24d, an encoder 24e, and a power source 24f. While the encoder 24e is shown as separate from the telemetry element 24d, the encoder 24e can be integrated within the telemetry element 24d.
  • the sensors 22 are calibrated to measure the player's physiological condition or parameter and then generate input data regarding each parameter.
  • the control unit 24 processes the input data, including filtering and conditioning as necessary, and then converts the data to signals.
  • the encoder 24e of the control unit 24 encodes the signals with a unique identifier, and the telemetry element 24d wirelessly transmits (as represented by the lightening bolts in Fig. 1) the encoded signals to the remote controller 40 which recognizes the encoded signals for further processing and calculation.
  • the telemetry element 24d can be a transceiver, or a separate receiver and transmitter.
  • the power source 24f can be a rechargeable battery or a disposable battery.
  • the parameter data transmitted from the reporters 20 to the controller 40 can be encrypted to increase the security of the underlying data.
  • the system 10 can include a cipher for performing encryption and decryption, and a key to parameterize the cipher.
  • each reporting unit 20 includes at least one sensor 22 such as a thermistor, which comprises resistive circuit components having a high negative temperature coefficient of resistance so that the resistance decreases as the temperature increases.
  • the temperature sensor 22 is a thermal ribbon sensor or a band-gap type integrated circuit sensor.
  • the sensors 22 can be a combination of accelerometers and thermistors operably connected to the control unit 24.
  • the sensors 22 are accelerometers and thermistors that are arrayed in an in-helmet unit 28 (see Fig. 4) for each player.
  • the sensors 22 are micro electro-mechanical system (MEMS) type sensors that use auscultatory and/or oscillometric measurement techniques.

  • the in-helmet unit 28 includes a flexible band 30 that houses the sensors 22 and the control unit 24.
  • the flexible band 30 is received within the internal padding assembly of the helmet 32, wherein the sensors 22 are positioned about the player's skull.
  • the in-helmet unit 28 is removably received within the helmet 32 to allow for testing and maintenance, including recharging of the battery power source.
  • the band 30 is dimensioned such that the sensitive axis of each accelerometer sensor 22 is orthogonal to the outer surface of the player's head.
  • the accelerometer sensors 22 are not positioned orthogonal to the head surface.
  • the accelerometer sensors 22 can be positioned either orthogonally or non-orthogonally to each other. While Fig. 3 depicts three sensors 22 within the control unit 20, the precise number of sensors 22 varies with the design of the system 10. In the embodiment where the system 10 measures the player's temperature, the temperature sensor 22 can be placed within the forehead pad of the helmet 32 or at other locations in protective equipment, such as shoulder pads, knee pads, etc.
  • the reporting unit sensors 22 measure the physiological parameter(s) and generate signals in response to the measured parameter value.
  • the sensors 22 can be configured to continuously generate signals in response to the parameter value, or generate signals only when the parameter value reaches or exceeds a threshold level.
  • the sensors 22 can be single-axis accelerometers that measure head acceleration but only generate signals when the sensed head acceleration surpasses 10 G's.
  • the control unit 24 processes the data signals and transmits them to the sideline controller 30 for calculation and monitoring of the player's physiological condition. As part of the processing step, the control unit 24 conditions and filters the signals, as necessary, and then encodes the signals with a unique identifier for transmission to the controller 40.
  • the signals sent from each control unit 24 can be divided with time division multiple access (TDMA), code division multiple access (CDMA), or frequency division multiple access (FDMA) technology. Encoding the signals with a unique identifier enables the controller 40 to properly multiplex and decode information from the various reporters 20 transmitting data. Accordingly, the system 10 simultaneously measures and transmits encoded data from a number of reporters 20 and then the controller 40 catalogs either the encoded data signal for further calculation, or the resultant calculation based upon the relationship between the reporter 20 and the player. Regardless of when the cataloging occurs, the controller 40 organizes each player's calculated parameter result for further analysis and/or monitoring.

  • CDMA code division multiple access
  • FDMA frequency division multiple access
  • an operator of the system 10 defines the relationship or association between the reporter 20 and the player when the player is issued a helmet or protective gear having the reporter 20. With the aid of the signaling device 60, the sideline personnel utilizing the system 10 can then monitor the physiological condition of select players based upon the cataloging of the calculated parameter result.
  • the active monitoring system 10, including the reporting unit 20, can be configured to measure the severity of the impact upon the player's body part based upon indirect measures of the impact event. This indirect measurement is accomplished through monitoring the deformation experienced by the player's protective gear, including the helmet, the shoulder pads, and the internal padding assembly associated within each.
  • An impact to a body part may be quantified by the body part's impact kinematics, which include a change in position, change in velocity and/or change in acceleration of the part over a select time interval.

  • the sensor output is dependent upon the distance between the particles and the sensor, wherein the sensor output measurements are applied to a rheologic model to calculate the impact force experienced by the equipment and/or pad element.
  • a mass-spring-damper model of the padding element and experimentally derived foam displacement and velocity values can be utilized in the model to estimate or calculate the impact acceleration and the magnitude of the applied impact force.
  • a highly sensitive sensor array can be used to calibrate the protective gear or padding element to determine the location of the magnetic particles therein relative to the Hall-effect sensor(s).
  • the impact to the body part is measured and calculated based upon the change in shape or dimensions of the protective gear and/or the padding element connected thereto.
  • Resistive sensing elements can be used where the resistance in the measurement device changes as a function of linear, torsional or shear displacement.
  • capacitive sensing elements can be utilized where the capacitance changes as a function of linear, torsional or shear displacement.
  • Shape-changing tape is an example of the sensing elements.
  • the reporting unit 20 includes a micro electro-mechanical system (MEMS) pressure transducer that detects pressure changes within an enclosed fluid bladder or air chamber, such as those used with the padding assembly of protective sports equipment, such as helmets and shoulder pads. When the protective equipment to which the padding assembly is connected receives an impact force, the padding assembly compresses the fluid causing a pressure change that is measured by the MEMS pressure transducer.
  • MEMS micro electro-mechanical system
  • the reporting unit 20 includes a temperature compensation element to improve the accuracy of the resulting measurements.

  • the system 10 categorizes the severity of the impact based upon the characteristics of the impact-related sound.
  • One benefit of these approaches is that the system 10 can positively quantify the fit of the protective equipment or padding element with respect to the player, and provide an alert if there is an improper equipment fit.

  • the controller 40 displays the affected player's identity, for example by name or jersey number, the measured parameter, and the time of the alert event.
  • the player's identity can be protected by use of a unique player identifier, which may be encoded or encrypted.
  • the controller 40 When the parameter result falls below the level and an alert event does not occur, the controller 40 continues to receive data from the reporters 20 and runs the requisite calculations. Further, when an alert event arises from one reporter 20, the controller 40 continues to receive and process data from the other reporters 20.
  • the time stamp allows sideline personnel and medical staff to correlate the calculated parameter to actual videotape of the sporting event that led to the alert event.
  • the controller 40 sends a signal to the signaling device 60 that alerts the sideline personnel to observe and investigate the condition of the player in question.
  • the player in question is quickly identified by the controller 40 due to the unique identifier provided by the reporting units 20 and the subsequent recognition of the identifier and the multiplexing performed by the controller 40. In this manner, the sideline personnel can efficiently evaluate the player at issue from the many players comprising the team.
  • the telemetry element 44 of the controller 40 can transmit a confirmation signal to each reporting unit 20 confirming that the signals sent by that reporting unit 40 were successfully received and that the data is complete for calculation purposes. This enables the reporting units 20 to conserve power since they do not have to repeatedly send data to the controller 40. In the event that the signals from a reporting unit 20 are not successfully received or that the signals are incomplete or skewed, the telemetry element 44 transmits a resend signal that instructs the reporter 20 to resend the signals from the control unit 24 for reception by the controller 40.

Abstract

La présente invention concerne un système (10) de surveillance d'un paramètre physiologique de joueur engagé dans une activité sportive. Ce système comprend une pluralité d'unités rapporteuses (20), un contrôleur (40) et un dispositif de signalisation (60). L'unité rapporteuse possède un agencement de dispositifs détecteur (22) qui mesurent le paramètre physiologique d'un joueur individuel et génère des données de paramètre. Le contrôleur reçoit ces données de paramètre émises à partir de chaque unité rapporteuse et traite ensuite ces données de paramètre de façon à calculer un résultat de paramètre. Lorsque ce résultat de paramètre dépasse une valeur prédéterminée, le contrôleur communique avec un dispositif de signalisation qui fournit une alarme à du personnel de ligne de touche de façon qu'il surveille le ou les joueurs en question. Ce système comprend aussi un dispositif de stockage à distance permettant de porter des données historiques recueillies par ce système, ce qui permet une analyse subséquente. Ce système peut surveiller un certain nombre de paramètres physiologiques de joueur, notamment l'accélération d'une partie du corps du joueur qui subit un impact et la température de chaque joueur.
