Description

FIELD

The present invention relates generally to devices, methods and systems in the field of tracking moving objects. More specifically, the present invention relates to devices, methods and systems for tracking attributes and/or movement and position of a ball used in a sports event.

BACKGROUND

Many sports are played on, in, within and/or around a defined sports playing area such as on, or around, a field or court, or in, or within, a gymnasium, arena or stadium. These sports frequently include a moving object, namely, a ball which is moved about, on or within the defined playing area. The ball is frequently moved in response to a force or action placed upon the ball and travels in a trajectory based upon the applied force and other environmental factors.

A variety of systems are currently available to track ball movement, trajectory and position in and on a playing area. For instance, many systems include multiple cameras which capture images or videos of ball movement, which images or videos are combined by computer implemented programs into an estimate of ball movement and trajectory. These systems are not precise and do not account for environmental factors. Moreover, these systems require a complex setup of multiple cameras at multiple angles in an attempt to capture the required data. Other systems include a GPS microprocessor embedded within the ball which communicates to appropriate receiving devices. Unfortunately, such devices affect the integrity of the ball and have not been accepted in practice as a result.

Systems also exist which allow broadcasters, and in particular television broadcasters, to project a computerized image onto the viewing screens of those who receive the broadcast. Common examples include the first down line that extends across the field during a United States football game, or a frame of an estimated strike zone in baseball, or an estimated trajectory of a homerun hit baseball. These systems are, however, not available in real time to the players or officials, and are, like the camera and video systems, merely an estimate based upon data gathered.

DETAILED DESCRIPTION

Devices, methods and systems for identifying ball movement, trajectory and position are provided. The system generally includes a ball adapted to communicate with one or more playing area communication elements such as, for example, one or more transmitters and/or receivers. In one embodiment, for example, the method and system includes a ball adapted to communicate and/or receive a signal from one or more transmitters positioned, on, in, at, near and/or under a playing area. In another embodiment, a ball is adapted to communicate, send and/or transmit a signal to one or more receivers positioned, on, in, at, near and/or under a playing area. In other embodiments, the system includes a ball adapted to communicate with one or more transmitters and/or one or more receivers positioned, on, in, at, near and/or under a playing area.

In one embodiment, the playing area communication elements is/are adapted to communicate and/or identify and/or display ball position based upon the signal communicated or received. A processor or computer may be provided to translate and/or process information received by the playing area communication elements into position, movement of the ball and trajectory.

The ball may be any suitable ball having the properties described herein. In particular, the ball has an outer surface or cover and, in one or more examples of embodiments, includes a one or more laces or threads on or near, or partially on or near, the outer surface or cover of the ball. The one or more laces or threads may be on a portion of the outer surface or cover, may be partially embedded in the outer surface or cover, may be adjacent to the outer surface or cover, and/or may surround or substantially surround the outer surface or cover, or a portion thereof. Examples of balls typically having one or more laces or threads include, but are not limited to, a baseball, a football, a soccer ball, a cricket ball, and a volley ball. While a ball having one or more laces or threads is identified in one or more preferred examples of embodiments, the disclosure may be applied to and by alternative balls and objects for which position, movement and trajectory identification are desired.

As can be seen by reference to FIGS. 1-6, the outer surface of the ball may include an area with a ball communication element, such as a wire communication element, an antenna element, or some other type of electrical or magnetic communication or signaling element. In one or more examples of embodiments, the laces or threads of the ball carry the ball's communication element. However, the communication element may be included in a portion of the outer surface, or a surface covering, may be embedded below the outer surface, or may be disposed adjacent to the outer surface or cover of the ball. In the illustrated examples, the ball's communication element is a thin wire of varying diameter and length, and may be made of any suitable material for the purposes provided herein. For example, the wire may be formed of a material which may accept, induce or carry an electrical and/or magnetic charge and/or current. The charge or current may be detectable by one or more playing area communication elements such as one or more receivers.

Alternatively, a signal transmission device may be used in place of, or in connection with, the ball's communication element or wire. Such transmission devices may be disposed, partially or entirely, and without limitation, in the laces or threads of the ball, on the outer surface of the ball, adjacent to the outer surface of the ball, or may be embedded inside of the ball. Such transmission devices may include, without limitation, passive or active transmitters, passive or active transmitter-receivers and/or passive or active identification tags or devices such as, for example and without limitation, radio-frequency identification (“RFID”) tags. For example, the communication element or wire may be in the form of, or connected to, a transmitter, which transmits a signal to another device, such as a receiver.

The ball's communication element or wire is durable, but semi-flexible in one or more embodiments such that it can be inserted, disposed, integrated and/or woven into the balls laces or threads. In other words, the communication element or wire may be integrated within the ball or embedded within the ball's laces or threads without affecting the integrity of the ball. In other examples of embodiments of the present invention, one or more of the ball's laces or threads, or a portion or part of the ball's laces or threads, such as one or more of the individual fibers or fiber threads that make up the laces or threads, is/are adapted or configured as the communication or signaling element or elements.

As previously mentioned, in one or more of the illustrated examples, the ball's communication element is a thin wire of varying diameter and length, and may be made of any suitable material for the purposes provided herein. For example, the wire may be formed of an electrically conductive material such as copper or some other type of metal. In other examples, the wire may be formed of other types of electrically or magnetically conductive materials. In yet other examples, the ball's communication element may be formed of any material which can accept, induce or carry an electrical or magnetic charge, current or signal. The charge, current or signal carried by the ball's communication element may be detectable by one or more playing area communication elements such as one or more receivers.

A device or ball in accordance with one exemplary embodiment of the present invention is illustrated in FIGS. 1-3. More specifically, FIGS. 1-3 show a baseball 100 having a cover 102. Cover 102 constitutes the outer surface 104 of baseball 100. Cover 102 is attached to baseball 100 using one or more laces 106 (also referred to herein as threads or strings). Baseball 100 also includes one or more ball communication elements or antennas 108 in this exemplary embodiment of the present invention.

Communication element 108 in the exemplary embodiment of the present invention shown in FIGS. 1-3 is a separate wire antenna that is disposed inside of, and runs through, laces 106 of baseball 100. It should be noted that the present invention is not limited to simply having the communication element or antenna disposed inside of the laces of the ball as a separate element (see FIGS. 11-12). In other embodiments, for example, the ball's communication element is integrated with, or into, the laces such as, for example, when the communication element is woven into the laces (see FIG. 12). This might be the case, for example, where both electrically (or magnetically) conductive and non-electrically (or non-magnetically) conductive materials or fibers are used to create the laces. In other embodiments of the present invention, the laces of the ball is/are adapted or configured as the ball's communication element or the communication element and the laces is/are actually one and the same structure (see FIG. 11). This would be the case where, for example and without limitation, the laces are made entirely out of an electrically conductive (or magnetically conductive) material.

Communication elements 108 can be of varying lengths depending on the particular application. In one embodiment, for example, communication element 108 is very short and only extends inside of one of the exposed portions of lace 106 which are visible on the outer surface of ball 100. In other embodiments, communication element 108 is longer and is disposed inside of lace 106 such that it extends through several of the exposed portions of lace 106 which are visible on the outer surface of ball 100.

Another device or ball in accordance with an alternative exemplary embodiment of the present invention is illustrated in FIGS. 4-6. More specifically, FIGS. 4-6 show a typical American football 200 having a cover 202. Cover 202 constitutes the outer surface 204 of football 200 and is secured in place using laces 206 (again also referred to herein as threads or strings). Football 200, like baseball 100, also includes one or more communication elements or antennas 208 in this exemplary embodiment of the present invention. Communication elements 208 in the exemplary embodiment of the present invention shown in FIGS. 4-6 is/are also a wire antenna that is disposed inside, and runs through, laces 206 of football 200.

It should be noted that while a baseball and a football are specifically illustrated in FIGS. 1-6, the baseball and football are provided for purposes of example only, and any suitable ball, examples of which are previously described herein, may be acceptable for use in accordance with the present system, method and devices.
