This invention relates to a monitoring and tracking system for use with a sports timing system such as the digital clock utilized in basketball games.
In many sports, such as basketball, the contest is divided into specific time periods or durations of play which requires accurate timing. The play periods are frequently interrupted for time outs for official or television commercial reasons, the limited number of time outs allocated to each team, and for fouls called by the officials. Such fouls or actions requiring penalties must be assessed to the player committing the foul, and play is stopped to allow, for example, any applicable free throws resulting from the foul. In addition, officials may stop play for a wet floor or an injured player.
As a result, the official time clock is frequently started and stopped upon such actions of any of the officials or the timekeeper. The officials signal the stop and start of play by whistles and the corresponding starting and stopping of the official time clock may be accomplished by the timekeeper pressing a button, or accomplished remotely and automatically by the officials' whistles using equipment such as shown in my U.S. Pat. No. 5,293,354, issued Mar. 8, 1994.
However, problems may be encountered when there is an inadvertent blowing of the whistle by an official who may be reluctant to own up to the error, or even by a spectator, or inadvertent pressing of the start/stop button by the timekeeper, and in identifying which official blew his whistle when there are multiple whistles blown. When calls by officials are in question, exact timing becomes important. Sports associations such as the Basketball Operations of the National Basketball Association (NBA) and NBA and college team offices routinely review videotapes of all games in their quality and accuracy review of the calls by the officials, and to insure and preserve the integrity of the game. Officials do make mistakes which can affect which team wins a particular game. When officials are later determined to have made a serious error, particularly one affecting the outcome of a game, they may be punished such as by suspension for a specified period. The potential of after-game detection and punishment of officiating error encourages diligence and correct performance by officials. Moreover, because of potential bias or other improprieties, it is important that official calls be scrutinized, even after a game is completed.
Since officials frequently signal a game stopping event such as a foul by three or four quick whistle blasts, the blasts of two officials may be simultaneous or overlapping. An analysis for quality control review of the event is helped by the precise recording of the whistle blasts or officials involved and specific sequence of events.
Television replays are not designed to present an accurate review of the actions of officials and do not identify who blew a whistle first in the case of multiple whistles. Moreover, if television playback is slowed down to closely examine a play, the whistle blasts frequently becomes inaudible.
It is also desirable that the electronic equipment, called a beltpack, worn by each official in a remotely actuable sports timing system be identified for quality control checking of the overall timing system and the equipment involved, including the battery strength of the beltpack.
As a result, it is highly desirous to have a record of each starting and stopping of play along with the identity of the initator and equipment initiating such action, to be able to display such information during the game, and to preserve and transmit such information to associations and others either during or after the game.
In addition, security of the remotely actuable system becomes of great importance to prevent inadvertent actuation by sources other than the officials.
Thus, there is a particular need for a secure remotely operated sports monitoring and tracking system which provides a record of which official initiated what action, at what time.
In accordance with one form of the invention, a sporting event game timing clock is provided with remotely actuable game clock signals generated by each of the floor officials or by the timekeeper. Each signal is provided with an identification code to enable the system to distinguish which official initiated the game action, be it stopping play or starting play.
A signal processor is provided to generate, display and store a record of each starting and stopping of play along with the identity of the official by name, and the identification of the specific equipment utilized by that official. A visual display is produced at the official timekeeper's position base station with all times provided digitally in one tenth of a second increments. The system includes a digital clock, preferably the official game clock, to the extent it includes digital access, to synchronize the recorded timing with the official game clock.
A sensor is positioned at each goal, namely a hoop switch in the case of basketball, to accurately detect the instant the game ball passes through the goal to enable the display and recording of the time of the goal. This is particularly important in turning off the shot clock near the end of the game to accurately indicate the precise time remaining in the game.
The record of the exact time of each start and stop of play, along with the identity of the official initiating the event is displayed and stored at the base station, and on a removable USB stick. Internet connections are provided enabling direct transmission of the game record to a supervisory organization such as the National Basketball Association (NBA) or team offices for quality review of the actions of the officials.
Connections may be made to one or more of the video cameras tracking the game to provide an associated visual record in which the actions of the various identified officials can be combined to simultaneously display video, timing and identification information.
The base station includes both visual, digital and a blinking light to demand the attention of the official timekeeper to game events such as stopping and starting play and the end of the game.

Each of the officials 100, 200 and 300 respectively on the basketball court can by blowing official whistle 11a, 11b and 11c, respectively, generate official signal 12a, 12b and 12c respectively to remotely stop game clock 20. This may conveniently be accomplished in the manner shown in my aforesaid U.S. Pat. No. 5,293,354. Official signal 12a, 12b and 12c, respectively, after being encoded by encoder 14a, 14b and 14c respectively, are transmitted by radio transmitters 16a, 16b and 16c, respectively to provide clock timing control signals 15a, 15b and 15c respectively to real time signal processor 26 of base station 24 by way of radio receiver 19. Signal generators 17a, 17b and 17c, respectively, are portable and adapted to be carried in a belt pack (not shown) attached to the belts of the officials.
Referring next to
Unit code 74 identifies the particular signal generator or belt pack 17a, 17b and 17c and official timekeeper control 5 initiating control signal 15a, 15b, 15c and 15d, respectively, to provide the identity of the official initiating the control signal and to aid in maintenance and repair of the units. Battery voltage signal 76 is provided as part of a built-in battery test or checking system to enable detection and replacement of weak batteries to avoid erratic, or failure of, control signals 1Sa, 15b and 15c, respectively.
Official Timekeeper Control 5 is connected to real time signal processor 26 through encoder 6 which identifies the timekeeper unit code 74 and system code 75 in the manner described above for encoders 14a, 14b and 14c. A battery voltage signal is not required since base station 24 is not a portable battery operated unit. Official timekeeper control 5 enables the timekeeper to start and stop game clock 20 and to perform other game functions as discussed below in connection with display unit 10 and
Base station 24 positioned for use by the official timekeeper encompasses all of the
Hoop switches 22 and 23, respectively, each include motion sensor 25 and hoop radio transmitter 27 and are positionable within or adjacent to goals such as basketball hoops 65 and 66, respectively, to provide goal signals 31 and 33 to radio 20 receiver 19 to enable essentially instantaneous signals when an object such as a basketball indicated by arrow 37 passes through the basketball hoop. Hoop switches 22 and 23 are positioned low adjacent basketball hoops 65 and 67 such that if a spinning basketball 37 goes in a basketball hoop “rattles” around, and then bounces out without passing completely through the basketball hoop, motion sensor 25 will not be actuated. One or more hoop switches 22 and 23 could be used for goals on other timed games such as soccer.
Signal processor 26 thus receives a plurality of signals—official signal 12a, 12b and 12c; system code 75; unit code 74; battery voltage 76; official timekeeper control 5 and hoop switch signals 31 and 33. These signals are combined with a clock or time signal from Game clock 20 or built-in clock 28 to provide game control signals which include who, what and when information which is displayed on display 10 as discussed below in connection with
Stored game data memory 46 which may be part of signal processor 26 stores the time of every actuation of game clock 20 along with the identification of the official who actuated the game clock and the applicable signal generator 17a, 17b and 17c, respectively, worn by the official on the floor; or in the case of the official timekeeper, actuation of start button 32 or stop button 34 of base station 24 (see

Display 10 also includes game data screen 45 which displays current game information including game clock indicator 38 indicating the amount of time remaining for the game period, and shot clock indicator 40 indicating the amount of time in which the team possessing the ball must shoot and at least hit the rim of the basket or turn the ball over. Data screen 45 also includes clock status indicator 42 which indicates whether the game clock is running or is stopped, and last game event indicator 44 which keeps the official timekeeper updated and aware of the last event which in the example shown, the clock was stopped at 01:15:8 by crew chief John Smith, using belt pack number 2. This type of information indicating who did what and when is extremely valuable in reviewing the actions of the officials during and after the game and can be used in combination with video recordings to evaluate such actions in ensuring the integrity of the game. Comment 49 has been entered through keyboard 61 to indicate that the penalty which was initially imposed was reversed after a conference of all officials.
Keyboard 61 (only a portion of the keys being shown) along with menu access button 36 is used to enter the desired game information on display 10 and may be a conventional computer keyboard or may be built in and selectively displayed on the display as a touch pad display. It is also used by the official timekeeper to enter data such as comment 49. Menu Access Touch Button 36 provides access to each unit code 74 signal which identifies the signal generator 17a, 17b or 17c, respectively, or official timekeeper control 5 generating a signal to which the desired individual identification is added through keyboard 61. The desired identification may be the individual's name and title such as official timekeeper, Crew Chief or official on the floor. This information is displayed and placed in memory to be combined with the time signal provided by game clock 20 or built in clock 25 and each control signal 15a, 15b, 15c and 15d, respectively. The record of who did what, when is thus made available during and after the game.
Game data such as that displayed by game data screen 45 and that included in stored game data memory 46 thus includes the name of floor official 100, 200 and 300 or the official timekeeper along with the exact time and nature of each of their control actions.
The signals from one or more video cameras (not shown) may be connected to video camera connector 67 to be added to stored game data memory 46 to add video images of the game. Display 10 includes audible signal 80 and visual signal 81 to alert the official timekeeper of each remote control action by officials 100, 200 and 300. Visual signal 81 and clock event indicator 47 include LED or light emitting diode bars which can turn red or green. When an official 100, 2006r 300, respectively, blows whistle 11a, 11b or 11c, respectively, to start game clock 20, the LED bar of visual signal 81 flashes bright green for three times while audio signal 80 sounds three beeps to alert the official timekeeper to the change in game status. Visual signal 81 then remains green at a lower light level to remind the official timekeeper that game clock 20 is running. When whistle 11a, 11b or 11c is subsequently blown to stop game clock 20 the visual and audible signals are repeated with the LED bar of visual signal 81 displaying two levels of red instead of green which remains red until game clock 20 is again started. A similar sequence of signals are provided on actuation of official timekeeper control 5.
At the same time that visual signal 81 and audio signal 80 are activated, clock event indicator 47 is actuated to illuminate numerals 1, 2, 3, etc. to identify which beltpack and hence which official initiated the event. The illumination of clock event indicator 47 like that of visual signal 81 is green when the event is starting game clock 20 and red when stopping the game clock.
Game data screen 45 also provides more detailed information and comments on game status as discussed above.
For sporting events other than basketball there may be more than three officials on the floor, field or playing area. Display 10 is for a system with eight signal generators such as 17a, 17b and 17c as evidenced by the eight identifiers on in range indicator 39, low battery indicator 41 and clock event indicator 47. This provides for spare signal generator channels and an increase in the number of officials beyond the three floor officials in the basketball example discussed above.
Tracker ball or mouse 9 is used in the conventional manner to select the desired menu item, or in entering data such as comment 49.
All timing information is provided in tenths of a second. Such precise timing information is extremely useful to the officials at the sporting event, and to those other officials who may remotely and/or subsequently review the game and actions of the game officials. In a basketball game it is only the final one minute of play in each period that tenths of a second are provided.
Menu access button 36 can also be used to display information in stored game data memory 46 on game data screen 45. For example, all of the foul or penalty calls of a single official in the game can be displayed to review whether that official favored one team in imposing penalties. This is, of course, only one consideration in insuring the integrity of the game by alerting association officials to any possible favoritism in close or disputed calls.
Keyboard 61 is also used for game set-up. The game set-up may, for example, include the insertion of the name of official 100, 200 and 300, and the identity of the belt pack or signal generator 17a, 17 or 17c carried by that official. Keyboard 61 can also be used to insert comments by the official timekeeper to be viewed later when the game calls are being reviewed. Comment 49 which indicates that the penalty was reversed after conference of all officials could also, for example, indicate that the official whistle 11a, 11b or 11c was sounded after the timekeeper's horn was sounded to signal a time clock violation.
