BACKGROUND

1. Field of the Disclosure

The present invention relates to a gaming table for use with gaming accessories such as gaming chips, plaques, playing cards, and dice, in casinos and gaming rooms. In particular, the present invention relates to a radio frequency identification (RFID) gaming table having cup shields configured to shield RFID antennas and to protect the RFID antennas from disturbances or interferences caused by electrical equipment, devices and wirings located in the table or near the table, pipes configured to insulate the electrical wirings in the base of the table, and a plurality of holes located in the shelves elf the base configured to ventilate heat from inside the base.

2. Discussion of Background Information

As compared to slot or video type games, traditional table games offer greater excitement for some players, group play, and often attract big money players, which can result in larger profit margins for the casino. Slots or video type games, however, often integrate a player tracking system that allows a computerized system to monitor a player's participation, such as how often a player plays and how much a particular player wagers. Furthermore, electronic gaming machines, such as slot or video type machines, accurately detect wagers and payouts, and thus are very efficient at preventing cheating.

In a table game environment, however, it is often difficult to track how much money a player wagers, and thus it is likewise difficult to accurately provide complimentary gifts or reward good customers to encourage a return to a particular property. Prior gaming tables use gaming tokens or chips embedded with RFID to track a player's betting for this purpose.

These prior gaming tables with the gaming chips are pervasively used in casino and gaming rooms for table games such as blackjack, poker, baccarat, craps and roulette. Particularly, these tables are provided with a RFID system including at least one RFID antenna for tracking and reading the gaming chips during a table game. These gaming tables further include low frequency and high frequency RFID chips, low and high frequency RFID readers, table layouts, playing cards, dice, gaming furniture, roulette wheels, table accessories, and other products that are used for casino table games.

However, even with these prior art bet tracking techniques, numerous wagering aspects may be missed or unmonitored, as discussed below. With the growing use of electronic technology for chip verification and tracking, today's gaming tables require more electronic equipment, devices and wirings to be installed in them. As such, these electrical devices and wirings may interfere with the RFID antenna, causing malfunctions in the RFID tracking system. Further, the electrical devices and wirings emit heat inside the base of the table, such that the performance of the electronic equipment and RF signals and receivers can be affected.

Accordingly, one drawback to these prior art systems is that existing RFID-type systems may not be able to accurately track every token due to interference caused by electronic equipment and wirings, particularly when numerous tokens are stacked. In addition, these prior art systems may suffer from inter antenna interferences if RFID antennas are spaced too closely together for games that have multiple and independent betting options per player seat, such as, for example, the game of baccarat. As a result, table layouts require sufficient spacing between antennas, which in turn may prevent desired felt layout or prevent presentation of the desired game.

Thus, there is a need for a gaming table designed and built especially to accommodate the electronic equipment that is increasingly required on gaming tables. Also, there is need for a gaming table configured to allow for ventilation and cooling of electronic equipment, to eliminate degradation in performance of the RF signals and electronic equipment, and to include specially-built areas for a shuffler and a bill validator that are ergonomically placed for dealer convenience and comfort while preventing any possible cheating.

As shown inFIG. 1, a gaming table10in accordance to one or more embodiments of the present invention is shown. In the illustrated embodiment, the gaming table10may have a tabletop20and a base50connected thereto. Base50is sufficiently configured so as to support the tabletop20. In one non-limiting embodiment, the base50may have a barrel configuration. In another embodiment, the tabletop20may have a semicircular shape, such that table game players may be positioned around the tabletop20and within reach of a dealer. Other shapes of the gaming table10—and more particularly the tabletop20and the base50—are possible, such as an oval, a circle, a square, a rectangle and the like. The gaming table may also be constructed with an open base instead of a closed barrel base, such as one that has a stretcher bar that ties two legs together. The open base may then be configured to store RFID and computer hardware.

As shown inFIGS. 2A,2B and2C, the top surface of tabletop20may be configured to receive gaming accessories44such as gaming chips, plaques, playing cards, dice and disks to name a few examples. The tabletop20may include a RFID antenna22configured to operate by detecting, reading, writing to, and/or tracking the gaming accessories. RFID22may be configured to perform any combination of the listed functions. As shown inFIG. 2A, as an illustration, the tabletop may have, but is not limited to, six antennas, such that six people may play a table game at the same time. One of ordinary skill in the art will appreciate that any number and combination of antennas may be positioned within the tabletop and still fall within the scope and spirit of the present invention.

The gaming table may have AC (alternating current) cables and may also have power supplies (or transformers) to power computers, displays, RFID readers, shuffling a machines, bill acceptors and validators, or any components that require power. Piping may be added to secure and protect AC cables, data cables, and antenna (RFID) cables, to keep them separated from each other and from equipment in the table. The piping may be insulated, or may be painted or coated with a pre-formulated paint or coating for better efficiency in preventing strong electromagnetic and harmonic disturbances caused by the AC cables to interfere with the RFID antennas.

The tabletop20may include a cup shield21that shields the RFID antenna22from the electromagnetic and harmonic disturbances caused by AC cables or the like. In this particular configuration, the RFID antenna22is located within range of certain disturbances but is shielded by the cup shield21so that antenna22is not detuned or looped. The gaming table10may also include different kinds of electrical equipment, devices and wirings that may interfere with the proper function of RFID antenna22. In particular, the table may include a plurality of electrical wires45,46and47located within or near the tabletop20, or within or near the base50. For example, the gaming table10may include AC wiring45and RFID wiring46for a RFID system. The RFID system is not limited to just the RFID wiring46, but may also include the RFID antenna22, and data wiring47for a Universal Serial Bus (USB) and other equipment for data transmission and communications.

Electrical equipment and wirings are capable of generating electromagnetic or harmonic interferences with the RFID antenna22, such that the RFID antenna22may incorrectly read RFID gaming chips, RFID playing cards or other accessories. As such, a cup shield21may be provided to shield and protect the RFID antenna22from electromagnetic interference (EMI) caused by the electrical equipment, devices and wirings located in the base50. Also, the cup shield21is configured to protect the RFID antenna22against radio frequency interference (RFI), such as AC harmonic radiation. Furthermore, in one particular embodiment, the cup shield21prevents the antenna from being read under the table, so as to discourage counterfeiting during a game. The cup shield21also may be configured to protect the RFID antenna22from being detuned, as further discussed below.

In the illustrated embodiment, the gaming table10includes a bill validator26located on the tabletop20and within reach of the dealer. As shown, bill validator26is installed in both the base50and the tabletop20. The bill validator26may be installed within a cage and constructed of any appropriate material, e.g., plywood and aluminum, on the right or left side of the dealer. The tabletop20may include an RFID float tray27configured to store the gaming accessories44. In the illustrated embodiment, the RFID float tray27is located on the top surface of tabletop20and within reach of the dealer, however, any configuration of the RFID float tray may be used without departing from the scope and spirit of the present invention.

The tabletop20may include a card shuffler24located on the tabletop20and within reach of the dealer, the card shuffler24is typically installed in the base50and the tabletop20. The card shuffler24may be located on the right or left side of the dealer. Furthermore, the tabletop20may include an LCD display43located within sight of the dealer such as in front of, on the right side or on the left side of the dealer's position.

The tabletop20may include a top base28assembled with a top insert29and a strip30placed on a dealer side. An inlay23is attached to the top base28. The inlay23includes rail drink openings with cup holders48and a dealer bar25attached to the strip30. The top base28and the top insert29both may be assembled together in any appropriate fashion, e.g., by using screws (not shown) or other fastening means. On the dealer side, the strip30may be fastened in any practical manner, e.g., with metallic inserts32or the like. The top insert29may have any one of the following: a cutout33for receiving the RFID float tray27, a cutout36for receiving the bill validator26, a cutout34for a LCD module including the LCD monitor43, and a cutout35for an antenna configured for testing, reading, writing to or tracking the gaming accessories44.

In one particular embodiment, the top insert29is coated or painted with a pre-formulated coating or paint to limit the reading field produced by the RFID antenna22. This specially pre-formulated coating or paint may also be applied to the interior of cup shield21. In such a configuration, the coating or paint prevents antenna from being read under the table so as to prevent cheating, prevents the antenna22from being detuned, and protects the RFID system from radio frequency interference and electromagnetic interference.FIG. 2Ashows the cross hatched portion identifying the top insert29painted with the pre-formulated paint. In one particular embodiment, the pre-formulated coating or paint is a water-based, conductive paint, with a copper composition. In another embodiment, the pre-formulated coating or paint comprises a water-based shielding material that is interspersed with copper and/or ferrite particles. The density and viscosity of the pre-formulated paint may be defined in an advantageous way such that the paint may be easily applied on wood and plastic materials to prevent detuning the antennas. Typically, the paint may be applied in all areas around the antennas without creating a closed loop.

For the manufacture of the inlay23, any appropriate hard material may be used such as wood, plastic, composites and the like of, for example, 1¼″ width. The inlay23may be assembled with several components of rail drink openings cut and prepared by using a computer numerical control (CNC) machine. After the inlay23is assembled, it is returned to the CNC machine for a final radial cut, and then it may be sent to a sanding and staining area to apply a layer of clear polyester, e.g., Duratek 904-045, combined with an organic liquid hardener, e.g., Superox Peroxide type “D,” each day for 6 days. Between each paint application to the inlay23, the hard wood may be sanded with sandpaper, e.g., #220. The inlay23having the rail drink openings may then be secured to the tabletop with appropriate fasteners, e.g., 1¼″ screws.

The dealer bar25may be made of oak, mahogany or other hard material with dimensions of, for example, ¾″×1½″. The same finish process as discussed above for the inlay23may be repeated for making the dealer bar25. The dealer bar25may be secured to the tabletop20using appropriate fasteners, e.g., seven 1½″×¼″ flat head bolts with shiny metallic finish. Other dimensions and ways of securing together the components of the gaming table are possible.

The gaming table10may include another antenna (not shown) for the RFID float tray27, such that this antenna may be located under the RFID float tray27.

FIG. 2Billustrates an alternate embodiment of tabletop90. In the illustrated embodiment, tabletop90is a two-piece construction comprising a top base91having an exchangeable insert bed85for receiving a table top exchangeable insert80. Similar to the top inset of tabletop20illustrated and described with respect toFIG. 2A, exchangeable insert80is coated with a pre-formulated shielding coating or paint81to limit the reading field produced by the plurality of RFID antennas located on the RFID antenna beds86,87,88,89in the tabletop90.FIG. 2Bshows the cross-hatched portion81identifying the pre-formulated paint. In one particular embodiment of exchangeable insert80, the pre-formulated coating or paint is a water-based, conductive paint, with a copper composition. In another embodiment, the pre-formulated coating or paint comprises a water-based shielding material that is interspersed with copper and/or ferrite particles.

In the particular illustrated embodiment ofFIG. 2B, exchangeable insert bed85is a recessed area on the surface of the top base91of tabletop90and is configured to receive the table top exchangeable insert80within its interior. In operation, the table top exchangeable insert80is placed on the top surface of tabletop90within the interior of the exchangeable insert bed85. A plurality of hollow circle members82,83,84are arranged in table top exchangeable insert80to accommodate the plurality of RFID antenna beds86,87,88,89in the tabletop90. Typically, the depth of the exchangeable insert bed85matches the thickness of the table top exchangeable insert80.

The diameter of the plurality of hollow circle members82,83,84are sized to fit the diameter of the plurality of RFID antenna beds86,87,88,89within the interior of the hollow circle members. The thickness of the table top exchangeable insert80is sized so that the surface of exchangeable insert80is coplanar with the surface of the RFID antenna beds86,87,88,89. In one embodiment, the thickness of the table top exchangeable insert80is ¾″, however, one skilled in the art can appreciate that any suitable thickness may be used for the table top exchangeable insert80without departing from the scope and spirit of the present invention.

As shown in the illustrated embodiment illustrated inFIGS. 3A,3B and3C, the cup shield21includes a cup base38and a lip37, configured such that the RFID antenna22is shielded by the cup base38. As such, the RFID antenna22may be installed, for example, inside the tabletop, e.g., in a countersink, and the cup shield21may be oriented in alignment with the RFID antenna22and secured, e.g., fastened to the underside of the tabletop beneath the RFID antenna22. In such a configuration, the cup shield21prevents disturbances coming from the neighboring environment (wirings, electronic devices radiations, etc.), and offers a good solution against detuning of the RFID antenna22due to metals and other electromagnetic sources. While the cup shield21may be coated inside with the pre-formulated paint or coating, it may alternatively include a ferrite plate as a more efficient, although more costly, solution to shielding the RFID antenna22against electromagnetic interferences. While the MD antenna22is illustrated as a round antenna, other shapes of antennas (e.g., square, rectangle, etc.) may be used, with the corresponding cup shield21having the corresponding shape. A minimum distance of separation, for example, one inch, is needed between the antenna plan of the RFID antenna and the uncoated and unpainted lip of the cup shield21.

In the illustrated embodiment, cup base38may have a smaller hole39at the center and a bigger hole40between the center and the circumference. The illustrated embodiment is for illustration purposes only and is in no way meant to be limiting of the installation of the cup. The smaller hole39is configured to assist in installing the cup shield21and in alignment with the RFID antenna22. For other shapes of cup shields, two or more small holes may be used to help with installation of the cup shields and indexing the position with the antennas. While the smaller hole39may be configured to assist in installing the cup shield21, the bigger hole40is utilized to assist in tuning the RFID antenna22with a screwdriver or other appropriate implement. Continuing with the illustrated embodiment, the lip37may have holes42configured so as to assist in securing the cup shield21to, e.g., the underside of the tabletop20. Neckline41may be configured to receive a cable in the cup shield21. The outside of the cup base38may be painted to protect the RFID antenna22from electromagnetic interferences or AC harmonics and also to prevent counterfeiting during a game.

As shown inFIG. 4, the gaming table10may include the base50. In the illustrated embodiment, the base50includes a top shelf51connected to a back panel57, a circular side wall59, a middle shelf52(shown inFIG. 6B), bottom shelf53(shown inFIG. 6C), and a support60. The back panel57has a folding door with the openings58and the middle and bottom shelves may have a plurality of holes. The openings and the holes are configured to ventilate heat from inside the base to outside of the table. The back panel may have, for example, a laminate plastic finish. The bottom shelf53may be finished with, e.g., black oil paint and shiny lacquer e.g., ML Campbell. The circular side wall59, the top, middle and bottom shelves51,52,53, and the back panel57, may be put together in any appropriate configuration to form the base50of the gaming table10, and may be covered with any appropriate material, for example, metal, fabric or plastic laminate. Furthermore, the gaming table10may be finished with any appropriate stain, tint or color, e.g., with polyester. Additionally, the base50may be configured for an open base table as well. For example, a stretcher bar is used to connect table legs and may be used as storage for RFID and computer hardware. Furthermore, depending upon the number, placement and use of the RFID antennas22, a gaming table may be configured so that it is not necessary to include the cup shield21. As should be readily apparent to one of ordinary skill in the art, many other configurations of the gaming table are possible without departing from the scope according to the present invention.

As shown inFIG. 5, the circular side wall59includes pipes61configured to insulate the electrical wirings45,46,47(shown only inFIG. 2A). Each of the pipes may have three holes for receiving the electrical wirings45,46,47. The pipes61are configured to contain, insulate and shield AC wiring (e.g. power supply cables), RFID wiring (e.g. antenna cables), and data wiring (e.g. network cables). In one embodiment, the pipes61are coated or painted with a pre-formulated coating or paint to limit the electromagnetic interference produced by the AC wiring, RFID wiring, and/or data wiring. In such a configuration, the coating or paint protects the RFID system from radio frequency interference and/or electromagnetic interference created by whatever wiring system is located within pipes61. In one particular embodiment, the pre-formulated coating or paint is a water-based, conductive paint, with a copper composition. In another embodiment, the pre-formulated coating or paint comprises a water-based shielding material that is interspersed with copper and/or ferrite particles.

Additionally, the pipes may be used to segregate the three families of cables. AC power is present in the gaming table10. AC cables for power supplies (or transformers) may be needed to power equipment and devices such as the LCD display43, the card shuffler24, the RFID antenna22, the bill validator26, computers, etc. The magnetic harmonics created by AC cables may disturb the RFID antenna22. It is preferred that the three families of wirings are arranged separately in the gaming table10. The pipes61may protect the wirings for better efficiency, and may help prevent strong electromagnetic disturbances for the antennas. Pipes61may be made of PVC or copper, for example, to protect the antenna cables. Pipes61may be installed in any appropriate manner and networked within and around the table base, for example, in the circular side wall59perpendicular to the bottom shelf53. Pipes61may help secure and organize the cables and protect them from harm. Also, base50may be built based on a structure comprising vertical columns of appropriate size, e.g., 63¾″ tall×4″ wide, an upper semicircular component64and a lower semicircular component65of the same width and material. Once the piping system has been finished, the interior part of the base may be covered with an appropriate material, e.g., ⅜″ Luan plywood (not shown). The base may then be painted to cover the bottom area with, e.g., oil paint, and then finished with, for example, ML Campbell shiny lacquer.

The gaming table10may have two cleats (not shown), fabricated of any appropriate material of, e.g., 1″ medium-density fiberboard (MDF), and finished with any appropriate material, e.g., plastic laminate and oil paint, on the interior side. One of the cleats may be attached to the upper semicircular component64of the base. The other cleat may be attached to the tabletop20.

The gaming table10may be fitted with aprons (not shown), i.e., illumination rails, installed on the exterior of the base50. The illumination rails may be built in any appropriate fashion, e.g., with two arcs of 1″ MDF covered with, for example, a plastic or metallic laminate on the exterior face, and may be painted on the other surfaces. The gaming table may also include a lighted foot rest rail, luminarias, and decorations with different colors of lights, or other illuminated objects and parts.

As shown inFIGS. 6A,6B and6C, the base50may be fabricated with a top shelf51, a middle shelf52and a bottom shelf53. In the illustrated embodiment, bottom shelf53has two holes55configured to receive two electrical boxes, and a plurality of additional holes56configured for wiring openings. These shelves may be covered with any suitable material, e.g., a plastic laminate. In particular, the middle shelf52and bottom shelf53may have a plurality of openings (holes)54configured to ventilate the heat emitted from electrical equipment, devices and wirings to the outside of the table.

Accordingly, the present gaming table has advantages for accommodating electronic equipment, including a RFID tracking system, without electromagnetic interferences within the RFID system. Other advantages include allowing ventilation and cooling of electronic/electrical equipment, elimination of signal interference of RFID transmitter and specially-built areas for items such as a shuffler and a bill validator that are ergonomically placed for dealer convenience and comfort while preventing any possible cheating.

What has been described are only some examples of a gaming table and method for making the gaming table according to preferred embodiments of the present invention. Accordingly, it is to be understood that various and numerous other arrangements may be devised by one skilled in the art without departing from the spirit and scope of the present invention as limited only by the accompanying claims.
