DETAILED DESCRIPTION OF THE INVENTION

(9) The following detailed description of the present invention references the accompanying drawing figures that illustrate specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the present invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the spirit and scope of the present invention. The present invention is defined by the appended claims and, therefore, the description is not to be taken in a limiting sense and shall not limit the scope of equivalents to which such claims are entitled.

(10) The present invention is directed to a down and distance marker system 10 that improves on existing down and distance marker systems by including a distance measurement system coupled to an electronic display which conveys not only the down, but also the measured distance to obtain a first down. Accordingly, as shown in FIG. 1, the present down and distance marker system 10 includes a first marker 12 for indicating the original line of scrimmage of the first down, a second marker 14 operably connected to said first marker at a fixed distance of ten (10) yards, and a down marker 16 which is independent of first marker 12 and second marker 14 which is used to mark the exact position of the football on the field for any given down. The system is described in U.S. patent application Ser. No. 14/211,906, the entire disclosure of which is incorporated herein by reference. As shown in FIG. 1, down marker 16 includes a display 50 and display housing 54 containing the display mounted at a top end 46 of marker 16.

(11) Another embodiment of the electronic down and distance system 10 is improved with additional wireless connectivity between down and distance marker 16 and a scoreboard or other stadium display. As shown in FIG. 1, either the down and/or distance marker 16 or other marker 12 or 14 would be equipped with a measuring device 52 may also include a wireless transmitter (e.g. 2.4 Hz Spread Spectrum or other known frequency or method) capable of communicating the current down, distance to a first down, and unit of measurement (e.g. yard, foot, inch) to a remote scoreboard and/or other connected device capable of processing the information for users/fan experience. This system may include an antenna, data transceiver, and microprocessor circuit within the measuring device 52. A dedicated communication link could also be designed between the down and distance marker 16 or other markers 12, 14 for the purpose of sending control data between the two units. This measuring device 52 and associated wireless transmitter may also be used for this purpose in addition to providing the linear distance between markers 14 and 16.

(12) In one example, the down marker 16 would act as the master unit and send instructions to the distance display 50 (a slave unit). When the user presses the “down advance” button 502 on the down marker 16, the master unit sends the new down to the slave unit and also an instruction to measure the distance from down marker to line to gain. The slave unit then initiates the measurement device to measure distance between markers 14 and 16 and display the distance on display 50 and/or transmits the data (down, distance, unit) to the remote scoreboard for display.

(13) Measurement device 52 determines the linear distance between down marker 16 and second marker 14. Measurement device 52 may be a sonic or light-based (laser) distance measurement device and may work in conjunction with a sensor 56 attached to rod 32 of second marker 14 when measurement device 52 is on down marker 16 or sensor 56 may be attached to down marker 16 when measurement device 52 is on second marker 14. For the present disclosure, a sonic distance measurement device includes RF signal technology and or other radio or electromagnetic wave signals. Measurement device 52 may also include any other known wireless distance measurement technology.

(14) In another embodiment, the display 50 of down marker 16 could include a display of a message to fans or viewers, including advertisements and recognition of sponsors, or other pertinent information that could selectively display content. In another embodiment, flags 24 and 38 of markers 12 and 14 could also include an electronic display (like display 50) and display messages or other items of information.

(15) FIG. 1 illustrates an embodiment of the present down and distance marker system that includes a camera 400 mounted on down marker 16, or markers 12 or 14, to broadcast and/or record plays from an on-field perspective. In one embodiment, camera 400 is a digital camera mounted on the on the down marker 16 that faces the field of play. In one embodiment, camera 400 is in communication with a memory for storing the video file. In one embodiment, the memory is designed to record the last six plays from scrimmage. For example, when the seventh play is recorded, the first play is removed. Further, when the eighth play is recorded, the second play is deleted removed and so on in a first-in-first-out sequence. However, the camera may stream or live cast a video feed, or have a memory configured to store any number of plays.

(16) One embodiment of the video recording system may include a digital fish-eye camera 400, memory storage/retrieval, microprocessor, power supply, Wi-Fi access point, and high data rate transmitter. The fish-eye camera provides a wide angle view of the field, however, any digital camera configuration could be used. The camera may be controlled by a remote control unit (described below) either on the sideline, press box, or other remote location. There may also be a housing on the sideline connected to AC power that could serve as one or more of the Wi-Fi connection point for the camera, the data storage/retrieval module, and wireless connection to the down marker 16 and remote control interface. This remote “server” could provide additional memory storage for any number of plays—possibly an entire game. This “server” could also be accessed by network television systems to be integrated into telecasts.

(17) FIGS. 2A-2C illustrates a feature that is included in the second marker 14. Second marker 14 includes a projected laser line 100 from a line to gain identification system 102 that corresponds to the football line to gain. The football line to gain marks the point on the football field at which the offense can obtain a first down—also referred to herein as the line to gain. In one embodiment, a laser or other light source will be in a projector 103 having a housing 104 with an included battery source (not shown) and on/off control 106. The line to gain identification system 102 may be mounted on the line to gain marker 14. Alternatively, an embodiment (not shown) includes the projector being attached to the down marker housing 54 or marker 16. Line to gain identification system 102 may be mounted on rod 32 to ensure that the line to gain identification system 102 is placed to exact placement of the projected laser line 100. The projected laser line 100 will be disposed perpendicular to inner edge 108 of the pole 14 (inner edge is closest to marker 12) and, in one embodiment, may extend outwardly from the rod 32 as shown in FIG. 2C. In one embodiment, the projected line extends around approx. 4-6″ in length from the rod 32. However, any distance that provides a sufficient length to allow the projected line 100 to project onto a football if it passes the line to gain is within the scope of the present invention. Markers 14 or 16 may also include a mechanism, device, or method for ensuring that the projected laser line 100 is perpendicular to the sidelines, such as square indicator, a bubble level or other known device.

(18) In use, if there is a question as to whether the offense has passed the line to gain, the ball is spotted and placed on the surface of field. The second marker 14 is brought from the sideline and positioned to identify the point on the field that corresponds to the line to gain. As shown in FIG. 2B, the projected laser line 100 can then be projected downward to project a line that extends 4-6 inches away from pole 14. As shown in FIG. 2B, if the projected laser line 100 appears on the ball 500, then the offense has passed the line to gain and has obtained a first down.

(19) FIG. 3 shows another embodiment wherein the second marker 14 may include an optical line to gain projector 150 for projecting an arrow stripe 152 displaying a visual indicator of the line to gain on the ground which may typically be activated on the sideline to provide the players a visual indication of the line to gain during play. In one embodiment, second marker 14 includes a projector 150 that projects an amber color stripe 152 on the sideline that replaces the vinyl arrow currently used. However, any color could be used. The vinyl products in use today can be a safety hazard to athletes who are trying to decelerate while approaching the sideline as the vinyl has less friction than the turf and will prevent the foot of the player from gripping into the turf. There have been many notable injuries attributed to players slipping on the current sideline markers which are placed on top of the playing surface. The visual arrow projects onto, and does not change the playing surface experienced by the players and eliminates this hazard.

(20) As shown in FIGS. 3A and 3B, the projector 150 may similarly be mounted to the second marker 14 pole or integrated into the distance marker 16. The optical line to gain projector unit 150 will be comprised of one or more of a high power light source (e.g. amber colored LEDs) 158, optic lens 160 for light shaping, rechargeable battery source disposed within the unit, a charger adapter port, and on/off power control 154. When power is applied, the light source 158 will generate a light that travel through the optic lens 160, which will shape the light beam to form an arrow display on the ground surface 156. In one embodiment, the line to gain projector 150 and the line to gain identification projector 103 could be combined into one unit with the same light source and the line-type being controllable by the operator and a selective application of the lens applied to the light source. In one embodiment, the optic lens 160 could be in an overlapped position such that the line to gain identification line could always be projected, with the larger arrow being selectively turned on and off over the identification line. This arrangement would provide efficiencies in using the same light and power sources.

(21) FIG. 4 illustrates a remote control unit 200 for operating the present down and distance system 10. Remote control unit 200 may include a housing 202, an advance button 204, an on/off button 206. In one embodiment, remote control unit may also include a reverse button 208 and a display change button 210 to change the display from the down and/or distance indicator to an informational display described above. In one embodiment, remote control unit 200 may comprise a keyfob-like device or other remote of similar size to advance down and distance displayed on the display 50 of marker 16. In order to provide a more convenient method for activating the “Down Advance” operations, the remote control 200 can be used. For example, in very cold or inclement weather, the official could keep his hand in his pocket and still operate the down marker 16 by using the remote control 200 and press the advance button 204 to wirelessly control the advancement of the downs on display 50 of marker 16. In one embodiment, the remote control 200 may be a low data rate transmitter circuit, microprocessor, and power supply. However, other known wireless signal/remote control systems are within the scope of the present invention. In a basic embodiment, a single button 204 on the remote 200 may be implemented (with possibility of adding additional buttons for enhanced functions) and when pressed would send a control signal to the down marker 16 providing for down advance on the display 50 of marker 16. However, any functions performed by the present down and distance system 10 may also be connected to such remote control 200.

(22) In one embodiment, the operation of projectors 103 and/or 150 described above may be controlled by such remote control unit. Further, remote control 200 may also the operation of control camera 400
