BACKGROUND
The embodiments described herein relate generally to electronic gaming machines and, more particularly, to electronic gaming machines including a wireless charging apparatus mounted in a pushbutton assembly, or “button deck” of such machines.
Many contemporary electronic gaming machines include a player interface configured to receive player input. The player interface (or “button deck”) may be arranged over a surface of a gaming machine cabinet, and may include a plurality of mechanical pushbuttons for manual activation by a player. For example, a player may interact with one or more mechanical pushbuttons on the button deck to select game preferences, activate a game sequence, or otherwise provide input to the machine.
As mobile communications devices (e.g., smart phones) have come into widespread use, some electronic gaming machines have been developed to include a wired charging port, such as a USB charging port, for charging a player's mobile communications device during gameplay. However, players are not typically equipped with a wireless charging cable, and even in the circumstance that a player keeps a wireless charging cable on hand, introduction of the cable over the surface of the button deck may clutter the button deck and/or interfere with gameplay.

Player interface 120 also includes a payout mechanism such as a printer 109 and/or a coin output mechanism 111. The payout mechanism is configured to output a payout to a player of gaming machine 100 based on an outcome of the game (e.g., a base game and/or a feature game).
Additional hardware may be included as part of gaming machine 100, or hardware may be omitted as required for the specific implementation. For example, although buttons or touch screens are typically used in gaming machines to allow a player to place a wager and to initiate a play of a game any input device that enables the player to input game play instructions may be used. For example, in some gaming machines a mechanical handle may be used to initiate a play of the game. Persons skilled in the art will also appreciate that a touch screen can be used to emulate other input devices, such as, for example, a touch screen that can display virtual buttons that a player can “press” by touching the screen where they are displayed.
In addition, gaming machine 100 may include a communications interface, such as, for example a network card 112. Network card 112 may, for example, send status information, accounting information and/or other information to a bonus controller, central controller, server or database and receive data or commands from the bonus controller, central controller, an/or server or database. In various embodiments (e.g., embodiments that employ a player marketing module), communications over a network may be via the player marketing module—e.g., the player marketing module may be in data communication with one or more of the above devices.
In various embodiments, components of gaming machine 100 may be distributed. For example, in an embodiment, input/output devices 106, 107, 108, 109, 110, and 111 may be provided remotely from game controller 101.
FIG. 5 illustrates such an exemplary distributed gaming system 200. Gaming system 200 may include a network 201, which, for example, may include a wired or wireless network, such as a Wi-Fi or BLUETOOTH network, an Ethernet network, an RS-232 network, and/or any combination thereof. In an exemplary embodiment, gaming machines 202, shown arranged in three banks 203 of two gaming machines 202, are connected to network 201. Gaming machines 202 may provide a player operable interface and may be the same as (or substantially similar to) the gaming machines 10 and 100 (as shown in FIGS. 2 and 3), or may have simplified functionality depending, for example, on various game play requirements.
One or more displays 204 may also be connected to network 201. For example, displays 204 may be associated with one or more banks 203 of gaming machines. Displays 204 may be used to display representations associated with game play on gaming machines 202 and/or used to display other representations, such as, for example promotional or informational material. Displays 204 may be the same as or substantially similar to display 14, as described above.
In a thick client embodiment, game server 205 may implement part of the game played by a player using gaming machine 202, and gaming machine 202 may implement part of the game. In such an embodiment, insofar as both game server 205 and gaming machine 202 may implement part of the game, they may collectively include a game controller. A database management server 206 may manage storage of game programs and associated data for downloading or access by gaming machines 202 in a database 206A. Typically, if gaming system 200 enables players to participate in a jackpot game, a jackpot server 207 may be provided to perform accounting functions for the jackpot game. A player tracking/loyalty program server 212 may also be provided.
In a thin client embodiment, game server 205 may implement most or all of the game played by a player using gaming machine 202, and gaming machine 202 may, in essence, functionally provide little more than the player interface. In such an embodiment, game server 205 may include the game controller. Gaming machine 202 may thus receive player instructions and transmit those instructions to game server 205. Further, in a thin client embodiment, gaming machines 202 may be computer terminals, such as, for example, personal computers, laptop computers, tablet computing devices, smartphones, and the like running software that provides a player interface. Other client/server configurations are contemplated and are within the scope of this disclosure. Additional details of a client/server architecture may be found in WO 2006/052213 and PCT/SE2006/000559, the disclosures of which are incorporated herein by reference in their entireties.
One or more servers may be provided to assist in the administration of gaming system 200. Such servers may include, for example, a gaming floor management server 208, and a licensing server 209 to monitor the use of licenses relating to particular games. An administrator terminal 210 may be provided to allow an administrator to run network 201 and the devices connected to network 201.
Gaming system 200 may communicate with other gaming systems and/or other local networks, such as, for example a corporate network, and/or a wide area network such as the Internet. Network communications may be filtered through a firewall 211.
Persons skilled in the art will appreciate that in accordance with known techniques, functionality at the server side of network 201 may be distributed over a plurality of different computers. For example, elements may be run as a single “engine” on one server or a separate server may be provided. For example, game server 205 may implement a random number generator engine. Alternatively, a separate random number generator server may be provided. Further, persons skilled in the art will appreciate that a plurality of game servers may be provided to implement different games or a single game server may implement a plurality of different games as required by the terminals.
In an exemplary embodiment, a player may place a wager using the game play mechanism 56. A game (or game session) may be initiated in response to placement of the wager, a plurality of symbols randomly drawn, and a game (or game session) outcome determined based upon the symbols drawn. A game outcome may be compared to a pay table (which may be stored in a computer memory) to determine a payout or award (also referred to herein as a win entitlement). Persons skilled in the art will appreciate that a player's wager can be varied from game to game dependent on player selections.
In various embodiments, a wager may include a selection of a number of lines to be played during a game session. Such lines may include an interconnected combination of symbol display positions. Each selected line may be evaluated to identify winning combinations of symbols. A pay table (e.g., a pay table stored in memory 64) may be referenced to identify a payout or award based upon an identified winning combination of symbols. In various embodiments, an award may be multiplied or increased by a multiplication factor as well.
In an exemplary embodiment, gaming machine 202 may generate an award that is not based solely upon a number of a lines selected. For example, “scatter” pays (e.g., randomly selected awards that are not identified based upon a plurality of adjacent symbols) may be awarded independently of a player's selection of pay lines.
With reference now to FIGS. 6-9, a wireless charging apparatus is described. The wireless charging apparatus may be coupled to and/or used with the electronic gaming machines and systems described above.

To this end, adapter plate 702 may include a first receiving surface 714 configured to receive and/or engage on pushbutton 610 and a second receiving surface 716 configured to receive and/or engage on wireless charging device 704. Thus, adapter plate 702 may be implemented between pushbutton 610 and wireless charging device 704 to securely mount pushbutton 610 and wireless charging device 704 within wireless charging apparatus 700.
Adapter plate 702 may be manufactured from any suitable material, such as plastic, and may be configured to move within housing 708 (e.g., in response to depression by a player of pushbutton 610) to mechanically engage, with pushbutton 610 and wireless charging device 704, with switch assembly 706. Thus, a player may mechanically depress pushbutton 610 within adapter plate 702 to initiate a “Spin” or “Bet” feature of pushbutton 610, as described above. Switch assembly 706 may, in response to selection by a player of pushbutton 610, electrically and/or mechanically engage a control circuit (not shown) within cabinet 12 of gaming machine 10 to transmit a signal to game controller 60 indicating that the player has selected or depressed pushbutton 610.
Wireless charging device 704 may include any suitable device for inductively charging a mobile communications device, as described above. Specifically, wireless charging device may include a coil, which may be energized during operation, such that wireless charging device 704 generates an electromagnetic field suitable to inductively charge a mobile communications device. To this end, wireless charging device 704 may be electrically and/or mechanically coupled to a power source, such as a power inverter, which may drive wireless charging device 704 during operation. In some embodiments, wireless charging device 704 is a wireless charging transmitter, such as a wireless charging transmitter model DMTX-19V15 W-EZ-SYS, available from the SEMTECH Corporation.
In the exemplary embodiment, housing 708 is a custom manufactured component that is configured to receive and support pushbutton 610, adapter plate 702, wireless charging device 704, and switch assembly 706. To this end, housing 708 may include an interior surface 718 that defines a recess 720 for receiving and supporting pushbutton 610, adapter plate 702, wireless charging device 704, and switch assembly 706. Like adapter plate 702, housing 708 may be manufactured from any suitable material, such as, for example, plastic.
In operation, wireless charging apparatus 700 may be mounted under or within button deck 600, such as at any location of a pushbutton 602-610. Specifically, wireless charging apparatus 702 may be mounted under or within button deck 600, such that wireless charging device 704 is seated a small distance under button deck 600, such as between 6 millimeters and 10 millimeters under button deck 600 and/or such that, during operation, a mobile communications device disposed in proximity to wireless charging apparatus is approximately 6-10 millimeters from wireless charging apparatus 700. Thus, any pushbutton 602-610 location may be configured to include wireless charging apparatus 700.
More particularly, housing 708 may be inserted within a mounting aperture (not shown) formed in button deck 600. In other embodiments, wireless charging apparatus 700 may be mounted within button deck 600 at any other suitable location, such as any location that would not otherwise include a pushbutton 602-610. In such an embodiment, wireless charging apparatus 700 may exclude a pushbutton, such as pushbutton 610, and may be mounted under a play surface of button deck 600. Button deck 600 may include, in either case, an indicator, such as a shaped indicator (e.g., a rectangular indicator, a circular indicator, and the like) that indicates a location over which a mobile communications device should be placed to receive a charge. In other embodiments, one or more indicia, such as the words “Charge Available” and/or “Charge and Spin Available” may be inscribed in proximity to wireless charging apparatus 702 to indicate a location over which a mobile communications device should be placed to receive a charge.
To charge a mobile communications device during gameplay, a player may place the mobile communications device in proximity to wireless charging apparatus 700, such as, for example, over pushbutton 610. In response to placement of a mobile communications device in proximity to wireless charging apparatus 700, wireless charging device 704 may generate an electromagnetic field (e.g., on detection of mobile communications device) that inductively charges the mobile communications device.
FIG. 8 is a top view of an exemplary wireless device 800, such as any near field communications (NFC) device, any BLUETOOTH wireless device, any WiFi wireless device, and the like, for use with wireless charging apparatus 700 (shown in FIG. 7). In some embodiments, wireless device 800 may be implemented with wireless charging apparatus 700, such that a mobile communications device may be substituted for pushbutton 610. Specifically, wireless device 800 may be networked between game controller 60 of gaming machine 10 and a controller of the mobile communications device, such that the mobile communications device displays a surrogate or replacement pushbutton (not shown) for selection by the player. Thus, wireless charging apparatus 700 may be configured such that a mobile communications device may be placed over pushbutton 610 (obscuring pushbutton 610 from operation by the player) without impacting the functionality of button deck 600.
To configure wireless charging apparatus 700 with wireless device 800, wireless device 800 may be mounted within wireless charging apparatus 700, such as, for example, between adapter plate 702 and wireless charging device 704 and/or between adapter plate 702 and pushbutton 610. However, in other embodiments, wireless device 800 may be mounted within wireless charging apparatus 700 and/or elsewhere within button deck 600 in any suitable location. In addition, and in various embodiments, wireless device 800 may include any suitable NFC communications device, such as, for example, an NFC device make and model number AS 3955 available for purchase from the AMS Corporation.
In the exemplary embodiment, wireless device 800 may also include a wireless controller 802, such as an NFC controller, which, as described above, may be networked between game controller 60 of gaming machine 10 and a controller of the mobile communications device. Like wireless device 800, controller 802 may include any suitable wireless device controller, such as an NFC controller available for purchase from the AMS Corporation for use with wireless device 800. To network wireless device 800 between game controller 60 of gaming machine 10 and a controller of the mobile communications device, controller 802 may be communicatively coupled (e.g., hardwired or wirelessly coupled) to game controller 60. Similarly, controller 802 may be wirelessly and communicatively coupled, such as via wireless device 800, to a controller of mobile communications device, which may be configured to receive and transmit a wireless signal, such as a near field communications signal, a BLUETOOTH signal, a WiFi signal, and the like.
In this embodiment, controller 802 may communicate with game controller 60 to provide one or more instructions, some as one or more computer-readable instructions, to the controller of the mobile communications device. Specifically, the instructions may enable the mobile communications device to display a replacement pushbutton on a display thereof, and the mobile communications device may execute the computer-readable instructions to display the replacement pushbutton. On selection of the replacement pushbutton, the controller of the mobile communications device may communicate, via wireless device 800, with game controller 60 to indicate to game controller 60 that a player has selected the replacement pushbutton. Thus, wireless device 800 and controller 802 may enable gameplay, even as a mobile communications device is wirelessly charged by wireless charging apparatus 700 and obscures the mechanical pushbutton 610 disposed under or below the mobile communications device.
FIG. 9 is a flowchart illustrating an exemplary process 900 of configuring wireless charging apparatus 700 in an electronic gaming machine 10. Accordingly, in the exemplary embodiment, gaming machine 10 may receive a credit input from a player using credit input mechanism 24 (e.g., at least one of a coin acceptor, a bill acceptor and/or validator, a card reader, and/or a ticket reader) to establish a credit balance for the player (step 902). Gaming machine 10 may, in addition, accept, by one of i) a pushbutton, such as pushbutton 610 and/or ii) a mobile communications device disposed in proximity to pushbutton 610 (and displaying a replacement pushbutton), a wager against the credit balance (step 904). Moreover, in the exemplary embodiment, wireless charging device 704, disposed under mechanical pushbutton 610, as described above, may generate an electromagnetic field that charges the mobile communications device while the device is in proximity to mechanical pushbutton 610 (step 906). Thus, a player may interact with a wireless charging apparatus 700 disposed in button deck 600 to initiate gameplay (e.g., via mechanical pushbutton 610 and/or via a replacement pushbutton displayed by a mobile communications device) as well as to charge the player's mobile communications device.
In various embodiments, the mobile communications device may display more than a replacement pushbutton, as described above. Specifically, in many embodiments, the mobile communications device may be arranged to communicate (e.g., via wireless device 800) with game controller 60 of gaming machine 10 to display any functionality, any player interface, any image, any game feature, and the like, typically displayed by gaming machine 10. For example, the mobile communications device may be networked to gaming machine 10, as described herein, to display all or a portion of a player interface typically displayed by and/or available on gaming machine 10 (e.g., one or more pushbuttons, as described above, typically displayed by and/or available on gaming machine 10). Thus, in some embodiments, the mobile communications device may be arranged to display any and/or all of pushbuttons 602-610 on button deck 600, irrespective of which pushbutton 602-610 is covered or obscured by the mobile communications device. In addition, in some embodiments, the mobile communications device may be arranged to display one or more primary and/or bonus games, various player tracking functionality, and/or any other information that is typically displayed on gaming machine 10.
As indicated above, the process may be embodied in computer software. The computer software could be supplied in a number of ways, for example on a tangible computer readable storage medium, such as a disc or a memory device, e.g. an EEPROM, (for example, that could replace part of memory 103) or as a data signal (for example, by transmitting it from a server). Further different parts of the computer software can be executed by different devices, for example in a client server relationship. Persons skilled in the art, will appreciate that computer software provides a series of instructions executable by the processor.
