Definitions

  • a system to identify gaming chips bet on a casino gaming table.
  • the system comprises a plurality of gaming chips each comprising an RFID device which comprises a unique RFID number and a peripheral bar code representing a denomination and a casino gaming table comprising player betting positions for betting one or more of the plurality of chips.
  • the system includes means associated with at least one given position for reading optical bar codes of any chip of the plurality of chips placed in the given position and providing the number thereof.
  • the system also includes means associated with the given position comprising two or more antennas for transmitting interrogation signals in an excitation sequence to respective RFID devices of any chip of the plurality of chips placed in the given position and for receiving a signal sequence from the respective RFID devices in response to the interrogation sequence, and means for processing a received signal sequence to identify respective unique RFID numbers and providing the number thereof and for comparing the number of chips provided by the means for processing and the number provided by the means for reading optical bar codes.
  • the two or more antennas comprises at least one other antenna with different a coverage pattern than the two or more antennas.
  • the one other antenna is positioned between the two or more antennas.
  • the means for transmitting interrogation signals in an excitation sequence does not provide for signals from every antenna associated with the at least one given position.
  • the means for processing employs a computer algorithm to determine which antennas are excited and the excitation sequence thereof.
  • the example that follows describes a casino Blackjack table with playing positions for seven players. Each player has an assigned "betting position" on the table to wager his RFID enabled gaming chips. If a player wins a hand, the dealer places his winnings in his betting position.
  • Various known means may be employed to associate an individual player's identity with one or more betting positions on a Blackjack table before, during or after a player's play session.
  • Fig. 1 shows three stacks of chips, Cl, C2 and C3, each stack with 21 chips sitting in adjacent betting areas on a Blackjack table top Tl. Below each of the three table top betting areas is an antenna depicted as a "target/sight" in Fig 1 and labeled Al, A2 and A3. The three stacks are in respective juxtaposed betting areas.
  • Each chip is peripherally bar coded with its denomination value using, for example, coding such as described in Pat. No. 6,514,140.
  • Each chip also has an embedded RFID tag with information comprising: (at least) a unique RFID number, and various other information.
  • the RFID tag may or may not have read/write capability.
  • One or more chips with RFID tags sufficiently proximal to antenna Al may be interrogated by antenna Al via a transmission from Al, and the tag(s) may transmit a respond to the interrogation with may be received by antenna Al.
  • This is a typical transmit interrogation and response cycle, and it is well known in the art.
  • two adjacent antennas are operated at different times because otherwise one antenna may activate a response from a chip over the other antenna.
  • Al may receive an unwanted response from a chip in the stack of chips C2 above A2 if A2 activates at the same time as Al, and visa versa.
  • Optically reading the chips bar codes can be used in conjunction with reading the RF tags, for reasons including the ability to assist in accurately locating and reading chips. For example, optical readings could identify the number of chips and of what denomination in a particular betting area so that the RF reading can be compared to the optical reading results. If discrepancies were to exist between the optical and RF readings, they could be resolved with further processing.
  • optical and RFID reading could work together to provide more accurate, corrected results in the event of, for example, a spurious RFID reading: If the optical system were to see 10 chips of the $25 denomination in a given betting position, but the RF readings included 11 $25 chip responses that appear to be from that betting position, the unique RFID numbers of the 11 chips could be compared to the left and right adjacent betting position RF readings in order to determine which one of the 11 chips' unique RFID numbers was also found in an adjacent position, so that its presence could be automatically removed from the RF reading tally that contained the 11 RF chips' responses. Or, in some cases if chip tracking provisions were being utilized, the tracking history of one of the 11 chips might reveal that it currently belongs to another player at another playing station. Thus, the discrepancy revealed by the combination use of RFID and optical readings could be resolved accurately.
  • Comparison of optical readings with RFID readings may be helpful or useful to: (i) detect the location of particular chips in order to (ii) help identify faulty or damaged RF or optically coded chips, (iii) detect counterfeit chips, (iv) detect stolen chips, and (v) detect chips being tracked for a variety of management or official (e.g., government) purposes, so that such chips can be to removed, replaced, repaired or deal with it as appropriate or according to a particular casino or other policy.
  • management or official e.g., government
  • casino management would like to bring the player evaluation/tracking abilities long used for slot machines to the gaming table.
  • casinos can more accurately track table play, without requiring more effort on the part of dealers and other casino personnel, and without changing the way table games are played.
  • Management can give more rewarding "comps" for players that provide more profit to the casino, as well more accurate, lower comps for players that get or have been getting more than they deserve.
  • Improved, more accurate evaluation of players' skill, detection of players who employ suspect strategies, and more accurate accounting of employee efficiency and performance, as well as tighter security for table game operations is also possible.
  • Craps In a game like Craps, for example, players do not have assigned betting position like on a Blackjack table. In Craps, different positions on the table relate to different bets which are indicated by the markings on the table covering. Different bets have different payout odds associated with them. For example, the "2" (snake eyes) and 12 (box cars) bets located in the "Field” pay double in the event a player placed such a bet and wins.
  • the RFID antenna array system described herein could be used to glean information about Craps table bets; for example, it could detect when a "2" Field bet is made, and, using known means to read the dice on the next roll, automatically determine if that "2" bet won or lost. If it won, it could then interrogate additional chip(s) placed as payout by the dealer next to this winning "2" chip(s) that had been bet, and (i) provide information as to whether or not the correct amount has been paid, (ii) associate the unique RFID number of the chip(s) in the payout with the unique RFID number of the chip(s) wagered. If the casino system were tracking the RFID numbers of chips in the possession of specific players, the chip(s) won on the "2" bet in this example could be associated with the specific player who made this winning "2" wager.
  • a system and method are provided using an antenna array for interrogating and locating RFID tags comprising more than one antenna means to transmit a series or set of signals, e.g., in a programmed sequence, the antenna means being able to receive signal responses from sufficiently proximal RFID tags, and associated program means to determine tag location from information derived (i) from responses to specific antennas and/or (ii) from non-responses to other specific antennas.
  • a heuristic program to improve system efficiency may be employed.
  • One embodiment described by way of example involves reading and locating gaming chips.
  • One purpose of the improved antenna invention described herein is to identify which RFID chips are bet and/or won at each individual (localized) player betting position so that information may be associated with the particular player making the bet.
  • a "position location strategy" will be referred to below in describing how the locations of individual chips are associated with betting positions on the table. (Well known means are used to associate specific betting position(s) with specific players.)
  • Fig. 6 depicting a single antenna, of the type described below, and to Fig. 6A depicting an antenna array comprised of multiple single antennas
  • the use of a high gain antenna provides for a more narrowly focused and subsequently more controlled directional pattern.
  • the use of low power provides for minimal reflected energy which could indirectly cause secondary reflections from exciting (chip tag) antennas of non-interest.
  • the antennas would need to be placed below the top playing surface of the table only far enough (the distance could be zero) such that the emitted pattern would be developed (cross-sectionally) enough by the time it reaches the table surface to provide for a fairly cross-sectionally uniform pattern from the table surface to somewhere about 4-5 inches above so as to read a stack of about 20, more or less, gaming chips.
  • the table surface material properties would also need to not vary with time (holding moisture, etc.), and be fairly transparent (loss-less) to the RF energy at the frequencies of interest (in this embodiment, we likely will be projecting and receiving through the table surface and one or more possible table coverings) so as not to distort the patterns or attenuate any transmitted/received energy (or to minimize the distortion of the patterns or attenuation of any transmitted/received energy).
  • the antenna structure part of the surface of the table.
  • the antenna may be embedded in the table surface or the covering, and a felt or some other gaming table top covering may or may not be used to cover the antenna and the table top.
  • the goal would be to have the emitted patterns as tight around the waist to provide for a higher degree of x-y positioning accuracy, with the z axis being the center of the emitted pattern axis (orthogonal, or reasonably orthogonal, to the table surface).
  • a HF (high frequency) system (for example, 13.56 MHz) may be preferred because these systems tend to work with magnetic fields (near field), rather than electric fields. They may be easier to create in defined areas (like positions on a table), and reading multiple tags may be somewhat easier. Also, water and other similar materials do not present as much of an interference problem. Higher frequency tags (for example, 916 MHz - 5.8 GHz) could also be used, but might result in a more challenging and higher cost solution with little if any performance advantage.
  • the position location strategy would be to enable one antenna at a time within a given zone and de-tune and de-activate (turn-off) all remaining antennas in that zone.
  • the size of the zone would be such that tag detection activities in the frequencies of interest in one zone using the antenna structure of choice would not impact synchronized or unsynchronized activities in another adjacent zone. If the total working area is small you might only have one zone, where as larger areas could provide for multiple (non-interfering) zones.
  • This scalable approach also allows for covering larger position detection areas while minimizing the impact on position detection times due to the parallel operation.
  • Zone size/area allows for parallel operation on a table surface; zone size provides for simultaneous activation of multiple antennas in a given excitation sequence and provides enough spatial separation so as to prevent interference from a neighboring zone.
  • Fig. 7 two antenna zones, each zone with 9 antennas, are shown; Zone 1 and Zone 2.
  • Fig. 7 shows the definition of zone matrix size based on the worst case cross- sectional emitted antenna element pattern as viewed looking into the table surface ( -z axis). With sufficient spatial separation, an antenna operating in one zone would not impact the operation of an antenna operating in a neighboring zone.
  • the worst case emitted pattern diameter or area of influence from an active antenna "d" defines the minimal zone separation or pitch "d" of active antennas operating in adjacent zones.
  • Fig. 8A four zones are shown, i.e., zones 1 to 4. Each zone has nine antennas. Each zone forms a quadrant of a square; the whole square as depicted has a total of 36 antennas.
  • the lower left antenna in each of the four zone-quadrants can be excited simultaneously in this embodiment. This is because the effective excitation/coverage area of each antenna, which is depicted by the circle shown around each lower left antenna in each quadrant, does not reach or overlap into any other active-at-the-same-time antenna area. Therefore, these four antennas cannot interfere with each other even if all four are activated simultaneously.
  • This exemplifies how system recognition/throughput efficiency can be improved by simultaneous operation of non-interfering antennas in adjacent structured zones: Instead of requiring enough time for 36 complete antenna activation cycles, only nine such simultaneous cycles would be required to poll all 36 antennas.
  • Fig. 8B shows activation of four antennas; each antenna at this point in the activation sequence is located in the center of its respective zone. These four centrally located antennas can be activated simultaneously in some sequence (for example) after those in Fig. 8A.
  • FIG. 8C shows activation of four antennas, possibly next in the activation sequence. These antennas are located in the upper right corner of their respective zone. These four antennas can be activated simultaneously (for example) after those in Fig. 8B. It should be noted however, that the antenna excitation sequence need not be consecutive, nor even include every antenna. In some embodiments only enough antennas need be excited to provide sufficient results to provide the information being sought. It is possible to employ a heuristic computer algorithm to dynamically determine the excitation sequence to improve system efficiency.
  • only one antenna per zone may be active at any given time with all non-selected (and non-active) antennas in the array for that zone being detuned and de-activated (turned-off) so as to not interfere with the enabled antenna and associated tags within range (i.e., tags that respond to the one enabled antenna in a given zone).
  • An algorithm as described below may be used for determining the sequence (and position) for enabling antennas. Preferably, the algorithm would account for the physical proximity of any excited antennas in adjacent zones to optimize (minimize) zone size.
  • Fig. 9 shows nine antennas arranged 3 x 3 that make up one zone.
  • the following example will describe how the physical location of one RFID tag positioned within the zone of this example could be determined.
  • This one tag itself in this example is not shown per se, but for the purpose of this example, this one not-shown tag will be referred to as "thatched tag", and the top center antenna will be referred to as the “thatched tag antenna”.
  • the thatching being referred to as shown in Fig. 9 is made up of vertical and horizontal lines (similar to lines on grid paper). (Of course, the location of more than one tagged casino chip in a stack of chips above the thatched tag antenna is possible.)
  • tag location information may be derived from (i) responses to specific antennas and from (ii) non- responses to other specific antennas, as this example demonstrates.
  • tag position i.e., the location of tags
  • Antenna 1 in a given zone would be enabled (excited), and the group ("group 1") of tags that subsequently respond to that first antenna would automatically be recorded and associated with antenna 1 activation.
  • Adjacent antenna 2 next in the excitation sequence would be enabled and the subsequent responding group of tags recorded and associated with antenna 2.
  • Antenna 2's group (“group 2”) would be compared by an automatic program against group 1 (those group 1 tags that responded to antenna 1). The result of the comparison of the two groups would reveal which tags were in group 1 but not in group 2, and visa versa. Tags that are new to, or added to, group 2 are closer to the second antenna in a direction moving away from antenna 1, and tags that responded in group 1 but did not respond in group 2 are closer to antenna 1 in a direction moving away from antenna 2.
  • tags adding to adjacent antenna's groups, and tags dropping out relative to inquiries from adjacent antenna's positions the physical location of tags present on the table surface can be determined.
  • antenna arrays only be placed in and around areas where chips would be present on the table surface, thus optimizing the sequence cycle speed required for position detection.
  • a Blackjack game has limited and more controlled chip placement areas on the table surface and would need a less complicated antenna array and excitation sequence than a table game with more positions, or with no specifically-assigned-to-one-player gaming positions, such as Craps.
  • antennas for a Blackjack table may be placed along a line (for example, a straight or a curved line).
  • a centrally located/zone centered lower gain (broader pattern, and perhaps higher power emitted patterns) surrounded by higher gain directional (as shown in Fig. 10C) allow for quick determination of the presence of tags in a macro sense within an entire zone such that zone areas not receiving a response to a macro inquiry do not warrant further higher resolution inquiries using the surrounding higher gain antennas. It is also possible to dynamically re-define zone and activation boundaries based on the macro presence response to ultimately speed tag detection/location cycle times.
  • Fig. 2 is similar to Fig. 1 but an additional antenna is shown beneath table top T2 in-between each chip stack's (C4, C5 and C6) betting area: from left to right the antennas shown in Fig. 2 are labeled A4, A5, A6, A7, A8, A9 and AlO.
