This application claims the benefit of U.S. Provisional Application No. 61/310,591, “Ball,” filed on Mar. 4, 2010, incorporated herein by reference.
BACKGROUND OF THE INVENTION1. Field
The technology described herein relates to a ball (or similar object) that can be used for sporting (or other) events and is instrumented to include technology to sense information about the ball (or similar object).
2. Description of the Related Art
The remarkable, often astonishing, physical skills and feats of great athletes draw millions of people every day to follow sports that range from the power of football to the grace of basketball. Sports fans are captivated by the unique abilities of the individual players, as well as the coordination of the team. As a result, there has been an interest in tracking objects at sporting events, such as game balls.
A ball (or other object) is provided to be used with a sporting event or other event. The ball (or other object) includes one or more electrical components (including active and passive components) positioned inside the ball so that data about the ball can be obtained (e.g., the location of the ball can be tracked). Various embodiments are disclosed for positioning the one or more electrical components in the ball.
Game balls for sports such as basketballs, footballs, soccer balls, volleyballs, rugby balls, etc. typically include an inflatable bladder covered with a layer of windings and encased in a layer of elastomeric material (referred to as the carcass of the ball). One or more additional layers of material, such as a cover or padding may be placed over portions, or all, of the outer surface of the carcass to form the ball.
The cover of the various balls is typically a flexible and soft material. Covers of game balls are commonly formed of leather, rubber, synthetic leather, or a polymeric material. In one embodiment, the cover includes a plurality of cover panels. In other embodiments, the cover is one panel.
One can imagine using the disclosed method for implanting electronics in other types of objects, such as a kite used for kite surfing. These kites have several inflated members that each contain a bladder. The “carcass” however is basically sail material. Such use might not be for an event, but rather for normal recreational use, or for emergency.
The bladder is an inflatable air tube that usually approximates the desired shape of the ball. The bladder is typically disposed within the windings, carcass and the cover. In alternative embodiments, the bladder can be disposed directly within the cover. The bladder enables the ball to retain a predetermined amount of air, thereby, achieving the desired air pressure within, or firmness to, the ball. The bladder is typically made of latex, butyl rubber or other suitable material. The bladder typically includes a valve that extends through the windings, the carcass and the cover for access by a user.
The layer of windings include one or more elongated threads which are wound around the bladder. The threads from the layer of windings reinforces the bladder and retains the general shape of the bladder. The threads are formed of a high tensile strength material (e.g., nylon). In alternative embodiments, the thread can be a textile, wire or other conventional thread material. In some embodiment, a ball includes a layer of reinforcing material between the bladder and leather that is not a winding. In one example, the windings can include 210 denier nylon thread. Some embodiments of a ball can be formed without the layer of windings. In other embodiments, the layer of windings can be formed through one or more segments of adhesive tape or similar material.
The carcass is generally in the shape of the ball and disposed over the windings. In one embodiment, the carcass can be formed by placing a plurality of carcass segments onto outer surfaces of the windings and then mulling the carcass segments over the wound bladder to produce a uniform spherical layer of material. The material of the carcass can also be injected, or otherwise inserted, within a mold to form the carcass. It is common for a portion of the carcass material to impregnate, bind to or otherwise engage the layer of the windings. In one embodiment, the carcass is made of an elastic material, such as latex. Alternatively, the carcass can be made of material such as butyl rubber, natural rubber, a synthetic polymeric plastic material, or other elastomeric material. In another alternative, the carcass can be a multilayered body including one or more layers of fabric or elastomeric material. In some embodiments, the ball will not include a carcass. Some embodiments of the ball will only include a bladder and a cover, without including windings and/or a carcass.
The technology for adding one or more electrical components in the ball can be applied to many different types of balls. The examples below show a football; however, the technology described herein can be applied to basketballs, volleyballs, soccer balls, rugby balls and other types of balls, tires, or other inflated objects
Football 10 includes one or more electrical components 24 positioned inside football 10. In one embodiment, the one or more electrical components 24 are positioned between bladder 22 and cover 12.
The one or more electrical components 24 can be any electrical components (active or passive) that could help track ball 10 or serve a different purpose. In one embodiment, the one or more electrical components 24 includes a battery (or other power source) and a transponder that can receive signals and transmit signals. In another embodiment, the one or more electrical components 24 can include only a receiver or only a transmitter, rather than the transponder. In one embodiment, the one or more electrical components 24 include a receiver connected to one or more light emitting diodes, as discussed below. The one or more electrical components 24 could also include a RFID tag, other type of RF transmitter, radar repeater, etc. Many different types of electrical components can be used with the technology discussed herein. In some embodiments, the one or more electrical components are active electrical components.
Because of the air pressure inside bladder 22, the wall of bladder 22 will be pushed up against cover 12 and pushed up against electrical components 24; therefore, holding electrical components 24 in place against cover 12.
Although
Other embodiments include multiple bladders inside the cover such that the one or more electrical components are positioned inside the ball between two or more of the bladders.
In one embodiment, the one or more electrical components 124 are positioned below laces 112 so if the laces are removed, the opening between panels 104 and 106 at the area of the laces will allow for the one or more electrical components 124 to be inserted into the football into position between bladders 120 and 122 or removed from the football. In one embodiment, a ball will include windings and elastomeric material over the multiple bladders, as discussed above.
In the embodiment of
Note the embodiments of
As discussed above, some embodiments can include multiple bladders. In embodiments that have multiple bladders, the bladders can be separate (not connected) or connected by welding them together or connecting tubes (or other passageways) between the various bladders. One advantage of connecting the bladders is to ensure consistent pressure throughout. Other advantages are that only a single inflation point must protrude through the outer surface of the ball, and the user only has to inflate from one point.
In some embodiments, the one or more electrical components can include one or more transmitters that can transmit one or more electromagnetic signals. If the transmitters transmit an RF signal, then the transmitter can be wholly within the cover of the ball. If the transmitter is going to transmit a signal in the visible light range, ultraviolet light range or infrared light range, then it may be necessary to position one or more communication components (connected to the transmitter) within holes in the cover of the ball so that these components can transmit their signal. In some implementations, these holes may be covered by any material that's transparent to the emission) For example, the cover of a football can include one or more holes and one or more LEDs can be positioned in those holes and connected to a transmitter. The LED (or another type of electromagnetic transmitter) can transmit a visible light signal, infrared light signal, ultraviolet light signal, or other type of signal. In other embodiments, the one or more communication components can be one or more sensors that can be placed in the holes in the cover to sense one or more signals from an external source. Those sensors can also be in communication with transmitter/receiver electronics within the ball.
One example of the communication component is an LED that emits an infrared signal. In another embodiment, the communication device could be an LED that emits a visible light signal and has a filter in front of it to filter out visible light and only transmit infrared light.
One side of communication component 450 is connected to or mounted on flexible material 454 which can be a printed circuit board, a flexible printed circuit board, a ribbon cable, or other flexible material. Flexible material 454 is positioned and sandwiched between cover 402 and bladder so that communication component 450 is anchored inside ball 400 and will not fall through the aperture in cover 402. A wire 456 is connected to communication component 450 and runs through ball 400 to a transmitter, receiver, transponder, battery or other component which is housed inside ball 400 using any of the embodiments discussed above. The flexible material can be fastened to the cover and/or the bladder using an adhesive (single or double sided tape, glue, or other). The material would not necessarily be flexible if the footprint is small enough.
Note that many of the embodiments discussed above with the football can be applied to other balls such as basketball, soccer balls, volleyballs, etc. The main difference is that the shape will change from the oblong shape of a football to a spherical shape of the soccer ball, volleyball, etc. This spherical shape can be divided so that multiple bladders can be used as discussed above as long as the composite group of bladders is in the shape of the desire shape of the ball. In some embodiments, an adhesive can be used between flexible material 454 and the bladder and/or between flexible material 454 and the cover. Therefore, the above-described technology can be used with other types of balls. (or even other inflatable equipment such as traction kites or tires).
Note that none of the drawings show the windings or elastometric material. This is done for illustration purposes. Some embodiments will not include the windings or elastomeric material. Other embodiments will include the windings or elastomeric material. In some embodiments that include windings and elastomeric material, the one or more electrical components can be outside of the bladder, windings and elastomeric material, and inside of the cover. Alternative arrangements can also be made. For example, the one or more electrical components can be inside the windings and/or inside the elastomeric material.
The above-described balls can be used in the systems that track the ball using any of various technologies known in the art. For example, the above-described balls can be used with systems described in any of the following patent documents, all of which are incorporated herein by reference in their entirety: U.S. Pat. No. 5,912,700; U.S. Pat. No. 5,862,517; and U.S. Provisional Patent Application 61/307,578.
