Abstract:
A method and apparatus that identifies and safely couples an insertably-removable auxiliary device (IRAD) to a processor so that games can be played over a communications link without damaging the IRAD or the processor. An auxiliary connector, into which the IRAD is inserted, is not connected to the processor until after the identity of the IRAD is determined. The processor resides in a communications device, such as a wireless telephone, walkie-talkie, toy, or the like. Upon the activation of an auxiliary mode, a user is prompted to insert an IRAD into the auxiliary connector. An IRAD used to play a game can be an auxiliary keypad, an auxiliary processor, an auxiliary display, a supplemental program module that stores computer-readable code, an electronic board game, an auxiliary graphical user interface (GUI) (e.g., auxiliary steering wheel, auxiliary joystick, virtual reality viewer), or a headset including a microphone and speaker.

CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]    This application is related to co-pending U.S. patent application Ser. No. 09/870,210 entitled “METHOD AND APPARATUS FOR SIMULATING GAME ACCESSORIES,” invented by Scott Wolinsky and filed on May 30, 2001.  
         [0002]    This application is also related to co-pending U.S. patent application Ser. No. 09/823,877 entitled “METHOD AND APPARATUS FOR IDENTIFYING GAME PLAYERS AND GAME MOVES,” invented by Scott Wolinsky and filed on Mar. 29, 2001. 
     
    
     
       FIELD OF THE INVENTION  
         [0003]    The present invention relates to the use of accessories with a communication device, such as a telephone or the like, to extend the capabilities and enhance the experience of using the device to play games over a communications link.  
         BACKGROUND OF THE INVENTION  
         [0004]    There are numerous known remote game systems in which players, present at various remote locations, can play a game by communicating coded information relating to the state of the game through a common communication network, such as a telephone line.  
           [0005]    By way of a first example, in U.S. Pat. No. 4,372,558 entitled “Remote Gaming Apparatus” and issued to Shimamoto et al. on Feb. 8, 1983, each player has a dedicated game apparatus that detects and displays the position of game pieces (i.e., chess pieces). Each dedicated gaming apparatus has communications hardware that transmits and receives, over a phone system, coded information relating to the position of the game pieces. In this manner, each dedicated gaming apparatus displays the current position of the game pieces as effected by both players.  
           [0006]    By way of a second example, U.S. Pat. No. 5,186,471 entitled “Interactive Telephone Gaming System” and issued to Vancraeynest on Feb. 16, 1993, discloses a gaming apparatus used with a telephone network which supports standard dual tone multi-frequency (DTMF) signals. One or more players use a modified telephone station to play a game with a network gaming apparatus by receiving a sequence of DTMF tones and replicating the same sequence DTMF tones by pressing tone keys that correspond to the received sequence of DTMF tones. Each tone key has a corresponding light emitting diode (LED) which illuminates in response to receiving a corresponding DTMF signal from the network gaming apparatus. The illumination of the LEDs provide visible cues to the player at the modified telephone station to assist the player in matching the auditory pattern of DTMF tones generated by the network gaming apparatus.  
           [0007]    By way of a third example, U.S. Pat. No. 5,273,288 entitled “Communication Terminal Used As A Game Machine” and issued to Teshima et al. on Dec. 28, 1993, discloses a communication terminal used to play a game with an opponent through a telephone line. The communication terminal comprises a push button type telephone connected parallel to the communication terminal so that a voice signal of the push button type telephone is simultaneously transmitted to the opponent with a PB signal and a position signal. Accordingly, it is possible to talk with an opponent during game play.  
           [0008]    By way of a fourth example, U.S. Pat. No. 6,080,064 entitled “Device For Playing Games Via A Communications Network, And A Game System Using A Communications Network” and issued to Pieterse et al. on Jun. 27, 2000, discloses apparatus using a pointing device such as a joystick or the keys of a telephone set to generate DTMF pointing signals. Pieterse also discloses using the keys of a telephone set to transmit game instructions, such as “Fire”, “Start”, “Stop” and “Hold”.  
           [0009]    Although these known remote gaming systems succeed in providing entertainment to remotely located game players, they pose a problem in that the equipment used to play games is large and bulky, and thus is not portable. Furthermore, the variety of the types of games played is limited based on the fixed design of the gaming systems.  
           [0010]    Additionally, computer games, played via a server located in a telephone network or over the Internet, normally require the user to subscribe to a service and/or pay to play a game. For such games, it is difficult to set up a game with a known opponent. Often, game players are playing alone or against a computer. In other cases, players participating in game play do not know who their opponents are, and thus the personal interaction with friends and family members is lost. Further, such games do not allow parties having a conversation to spontaneously play a game by placing their communication devices in a game mode.  
           [0011]    It is therefore an object of the present invention to incorporate a flexible compact gaming system into a portable communication terminal, such that parties having a conversation via a communications link can initiate game play, or carry out other specialized communication functions over the communications link at any desired time during the conversation.  
         SUMMARY OF THE INVENTION  
         [0012]    In accordance with the principles of the present invention, the above and other objectives are realized in an apparatus and method for enabling a user, already engaged in conversation with another party over a communications link using a communications device, to insert additional peripherals (auxiliary devices), having additional processing, memory, software and game move control capability, into a communications device to play a game over the communications link. The present invention can be incorporated into wireless telephones (e.g., cellphones), walkie-talkies, wireless toys and other types of transceivers.  
           [0013]    More particularly, once a communications link (e.g., wired, wireless, etc.) is established between two or more communications devices, each device may be placed in an auxiliary mode which waits for an insertably-removable auxiliary device (IRAD) to be inserted into an auxiliary connector mounted on a surface the communications device and be identified, prior to being connected to a processor residing within the communications device. In certain cases, a signal may be generated and sent over the communications link to the other communications device(s), indicating to a party the type of IRAD that has been inserted in another party&#39;s communications device (e.g., a Donkey Kong supplemental program module). Furthermore, each IRAD will have an identity that can be read, displayed and/or processed by a processor within the communications device that operates independently to carry out communications functions but interacts with the IRAD to carry out auxiliary functions, such as providing a medium for playing a game.  
           [0014]    In one embodiment of the present invention, a wireless telephone is used by a game player to play a game with at least one other game player over a communications link. The wireless telephone includes an auxiliary connector mounted on a surface of the wireless telephone and an IRAD. The IRAD is used to play the game only after the IRAD is inserted into the auxiliary connector and identified.  
           [0015]    The wireless telephone may further include a keypad, a processor and a gateway circuit. The key pad is used to dial a telephone number to establish the communications link. The gateway circuit is coupled to the auxiliary connector and the processor. The auxiliary connector is coupled to the processor through the gateway circuit only after the IRAD is inserted into the auxiliary connector and identified.  
           [0016]    The wireless telephone may further include an indicator circuit and an auxiliary device identification circuit. The indicator circuit is coupled to the processor and indicates that the IRAD should be inserted into the auxiliary connector, by outputting a visual message and/or an audible message. The auxiliary device identification circuit is coupled to the auxiliary connector, the processor and the gateway circuit. The auxiliary device identification circuit may be used to identify the IRAD. The IRAD may be an auxiliary keypad, an auxiliary processor, an auxiliary display used to view the game, a supplemental program module that stores computer-readable code, an electronic game board, an auxiliary graphical user interface (GUI) (e.g., a steering wheel, joystick, virtual reality viewer, or the like), a headset including a microphone and speaker, a video camera, a computer, a fax machine, a voice/video/data recorder, or the like.  
           [0017]    In another embodiment of the present invention, a method is used by a game player to play a game with at least one other game player over a communications link. The method includes inserting an IRAD into an auxiliary connector mounted on the surface of a wireless telephone. The IRAD is then identified. The IRAD is used to play the game only after it is inserted into the auxiliary connector and identified.  
           [0018]    The wireless telephone may include a processor. The communications link may be established using the wireless telephone. An indication that the IRAD should be inserted into the auxiliary connector may be implemented by outputting a visual message and/or audible message. The auxiliary connector may be coupled to the processor only after the IRAD is inserted into the auxiliary connector and identified.  
           [0019]    In yet another embodiment of the present invention, a wireless telephone is used by a game player to play a game with at least one other game player over a communications link. The wireless telephone includes an auxiliary connector mounted on a surface of the wireless telephone, an IRAD used to play the game, and a processor which couples with the IRAD only after the IRAD is inserted into the auxiliary connector and identified.  
           [0020]    In yet another embodiment of the present invention, a wireless telephone is used by a game player to play a game with at least one other game player over a communications link. The wireless telephone includes an auxiliary connector mounted on a surface of the wireless telephone, a processor, and a gateway circuit which couples the processor to the auxiliary connector only after an IRAD used to play the game is inserted into the auxiliary connector and identified.  
           [0021]    In yet another embodiment of the present invention, an apparatus used to play a game includes an auxiliary connector mounted on a surface of the apparatus, a processor, and an IRAD used to play the game, wherein the IRAD is coupled to the processor only after the IRAD is inserted into the auxiliary connector and identified.  
           [0022]    The apparatus may be a wireless telephone. The apparatus may be connected to at least one of a set-top box, a television and a video player/recorder. The apparatus may further include a gateway circuit coupled to the auxiliary connector and the processor. The auxiliary connector may be coupled to the processor through the gateway circuit only after the IRAD is inserted into the auxiliary connector and identified.  
           [0023]    In yet another embodiment of the present invention, an apparatus used by a game player to play a game includes a connector, a processor and an indicator circuit.

The indicator circuit indicates to the game player that a particular type of insertably-removable auxiliary device (IRAD) should be inserted into the connector.  
           [0024]    The apparatus may receive information about the particular type of IRAD over a communications link. A first wireless telephone may transmit the information to the apparatus over the communications link. The apparatus may be a second wireless telephone. The indicator circuit may output at least one of a visual message and an audible message that includes the information.  
           [0025]    In yet another embodiment of the present invention, a telephone is used to play a game with a remotely located game player. The telephone includes a keypad, a connector and an IRAD. The keypad is used to dial a telephone number of the remotely located game player. The IRAD is used to play the game. The IRAD is inserted into the connector after the telephone number is dialed and a communications link is established with the remotely located game player.  
           [0026]    The IRAD may be at least one of a processor, a display, a supplemental program module that stores computer-readable code, an electronic game board, and a graphical user interface (GUI). The telephone may further include an indicator circuit which prompts a user of the telephone to insert the IRAD into the connector in response to the user activating an auxiliary mode of the telephone.  
           [0027]    In yet another embodiment of the present invention, a method used to play a game with a remotely located game player includes establishing a communications link by dialing a telephone number of the remotely located game player, and inserting an auxiliary device, used to play the game, into a connector provided on a surface of a telephone used to dial the telephone number.  
           [0028]    In yet another embodiment of the present invention, a communication apparatus includes a connector, and a circuit which automatically prompts a user of the apparatus to insert a particular type of auxiliary device into the connector, in response to the circuit receiving information over a communications link from another communication apparatus that identified the particular type of auxiliary device. The communication apparatus may be at least one of a wireless telephone, a wired telephone, a walkie-talkie, a wireless toy, and a transceiver.  
           [0029]    In yet another embodiment of the present invention, a method of implementing an auxiliary feature of a communication apparatus including a processor includes prompting a user of the apparatus to insert an auxiliary device into a connector provided on a surface of the apparatus in response to the user activating an auxiliary mode of the apparatus. The method also includes selectively coupling the inserted auxiliary device to the processor, only after the auxiliary device has been electronically identified by the apparatus.  
           [0030]    In yet another embodiment of the present invention a communications device includes a connector, a processor, a gateway circuit coupled to the connector and the processor, an auxiliary device identification circuit coupled to the connector, the processor, and the gateway circuit, and an IRAD.

           [0031]    The IRAD may be coupled to the processor through the gateway circuit when at least one of the auxiliary device identification circuit and the processor validates the identity of the IRAD. The communications device may be one of a wireless telephone and a wired telephone. The IRAD may be used by a game player to play a game with at least one other game player over a communications link.  
           [0032]    In yet another embodiment of the present invention, an IRAD is used to play a game when inserted into an auxiliary connector coupled to a game system circuit. The IRAD includes a connector that selectively mates with the auxiliary connector, and an identification circuit. The IRAD is not used to play the game until after (i) the IRAD is identified (ii) the identity of the IRAD is transmitted over a communications link, and (iii) a response to the transmitted identity is received over the communications link. The game system circuit may be a component of a wireless telephone, and the communications link is established via an antenna of the wireless telephone. The IRAD may further include a supplemental program module that stores computer-readable code used to play the game.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0048]    The present invention is an apparatus and method using insertably-removable auxiliary devices (IRADs) to play games and to provide a means for interfacing different types of auxiliary apparatus with a portable telephone. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that these specific details need not be used to practice the present invention. In other instances, well known structures, interfaces, and processes have not been shown in detail in order not to unnecessarily obscure the present invention.  
         [0049]    Referring now to FIG. 1, wireless communication between two players is illustrated in accordance with the present invention. Scott calls his 11-year-old son Bobby and informs Bobby over an established communications link that he will have to work late. Both Scott and Bobby are each equipped with a wireless communication terminal  100 A,  100 B, in accordance with the present invention. During their conversation, Scott asks Bobby, “what game would you like to play?” Bobby indicates that he would like to play “Pokemon Puzzle League.” Scott and Bobby energize an auxiliary (AUX) mode button on each of their terminals. Before doing so, the terminals performed as standard cellphones. Upon activating the AUX mode, the terminals indicate, either via audible or visible means, that an AUX device should be inserted into the terminal. Scott searches through a series of game cartridges  130 ,  135 ,  140 ,  145 ,  150 ,  155 ,  160  and  165  (stored conveniently in a pouch also used to carry the telephone, or in Scott&#39;s desk drawer) and inserts a “Pokemon Puzzle League” game cartridge  160  into an auxiliary connector on his terminal. Scott&#39;s terminal will then indicate that a “Pokemon Puzzle League” game cartridge has been inserted into the terminal after communicating with an ID circuit within game cartridge  160 . Scott&#39;s terminal will then transmit a signal including the identification of the game cartridge to Bobby&#39;s terminal over the previously established communications link. Bobby&#39;s terminal then processes the signal and indicates that a “Pokemon Puzzle League” game cartridge should be inserted into Bobby&#39;s terminal. Once Bobby inserts the correct game cartridge, and the identification of the inserted game cartridge is confirmed, Bobby&#39;s terminal will send a signal back to Scott&#39;s terminal indicating that the game may begin. As an alternative, one game cartridge could be used in Scott&#39;s terminal to host a game played by both Scott and Bobby. At the end of the game, the players may remove their game cartridges and insert a different game cartridge. Thus the game cartridges are “insertably-removable” into and from an auxiliary connector located on each of their terminals.  
         [0050]    Both Scott and Bobby may insert auxiliary displays  125 A,  125 B into their respective terminals such that they can more easily view the game on a larger screen. Scott and Bobby may also insert a control device, such as an auxiliary joystick  110 , to control player movements during the game. Other games may require an auxiliary steering wheel  105 , auxiliary microphone, speaker or headset  115 , an auxiliary virtual reality viewer  120 , or the like.  
         [0051]    [0051]FIG. 2A shows an IRAD  214  in accordance with one embodiment of the present invention. The IRAD  214  includes a multi-pin connector  212  directly affixed to the IRAD  214 . The connector  212  mates with a connector present on the surface of a communications terminal (e.g., wireless telephone) used in accordance with the present invention. This embodiment provides the most compact and convenient design for practicing the present invention.  
         [0052]    [0052]FIG. 2B shows an IRAD  220  in accordance with another embodiment of the present invention. The IRAD  220  includes a multi-pin connector  222  that is connected to an auxiliary device  224  through a cable or other communication means  226 . The connector  222  mates with a connector present on the surface of a communications terminal (e.g., wireless telephone) used in accordance with the present invention.  
         [0053]    [0053]FIG. 2C shows an IRAD  230  in accordance with another embodiment of the present invention. The IRAD  230  includes a multi-pin connector  232  directly affixed to a receiver  234 . The connector  232  mates with a connector present on the surface of a communications terminal (e.g., wireless telephone) used in accordance with the present invention. The receiver  234  receives instructions from an auxiliary device  236  via a wireless (or wired) medium  238 . Thus, although the auxiliary device  236  may be remotely located from the terminal, it is equivalent to being an insertably-removable device, because it communicates with such a device.  
         [0054]    [0054]FIG. 2D shows an IRAD  240  in accordance with another embodiment of the present invention. The IRAD  240  includes a multi-pin connector  242  directly affixed to a transmitter  244 . The connector  242  mates with an auxiliary connector present on the surface of a communications terminal (e.g., wireless telephone) used in accordance with the present invention. The transmitter  244  sends instructions to an auxiliary device  246  via a wireless (or wired) medium  248 . Thus again, although the auxiliary device  246  may be remotely located from the terminal, it is equivalent to being an insertably-removable device, because it communicates with such a device.  
         [0055]    [0055]FIG. 3 shows an example of an IRAD which is a game cartridge inserted into a wireless telephone. Once inserted and identified, an acknowledgement of the type of the IRAD may appear on a display of the wireless telephone, or may be audibly outputted by a speaker of the wireless telephone. The IRAD will not be allowed to interact with a processor within the wireless telephone until properly identified.  
         [0056]    [0056]FIG. 4 provides an example of the broad concepts that may be practiced using the present invention. The present invention enables a wireless telephone to be used as an interface for any specialized auxiliary communications and/or control devices, such as a video camera  405 , displays  410 ,  420  (e.g., computer monitor, cable set-top box/television, or the like), computer  415 , voice/video/data recorder  425 , and fax machine  430 , to communicate over a communications link established using the wireless telephone.  
         [0057]    [0057]FIG. 5A shows that a plurality of IRADs may interface with a wireless telephone at the same time in accordance with the present invention. Furthermore, FIG. 5A illustrates a hand-held portable device, comprising a fixed display that presents telephone call information (e.g., telephone number 215 855 6958) and an insertably-removable auxiliary display which is used by a user to view information not presented on the fixed display (e.g., a game). The auxiliary display adds “real-estate” to the device and enhances the viewing of specific types of information. It would not be practical to view a monopoly board on the small fixed display provided by standard wireless telephones. The use of an IRAD enables a user to take advantage of using a small base unit for basic tasks, such as establishing a communications link, while enabling the user expand the features of the base unit as desired by attaching IRADs.  
         [0058]    [0058]FIG. 5B shows an embodiment of a game cartridge and display used for playing a game of checkers over a communications link established by a wireless telephone in accordance with the present invention. Note that information about the players is shown on the wireless telephone&#39;s display, while the game board and player moves are displayed on an auxiliary display that operates in conjunction with an auxiliary game cartridge.  
         [0059]    [0059]FIG. 5C shows another embodiment of a game cartridge and display used for playing a game of chess over a communications link established by a wireless telephone in accordance with the present invention. Again, note that information about the players is shown on the wireless telephone&#39;s display, while the game board and player moves are displayed on an auxiliary display that operates in conjunction with an auxiliary game cartridge.  
         [0060]    [0060]FIG. 5D shows another embodiment of the present invention. A communications terminal (e.g., a wired telephone) contains multiple electronic game boards (e.g., chess, tic-tac-toe, battleship, checkers, or the like) inserted into its base. The game boards can be pulled out as desired, or they can be spring loaded and pop out when a button on a particular game board is depressed. Ribbon cable may be used to connect the circuitry from the individual game boards to the connectors on the terminal. Each of these electronic game boards provide specialized software and functions to play a particular game.  
         [0061]    [0061]FIGS. 6A, 6B and  6 C provide examples of where auxiliary connectors may be positioned on the side of a wireless telephone (FIG. 6A) in accordance with the present invention. For PC cards, a multi-pin connector (FIG. 6B) affixed along the length of the PC card may be inserted into a rectangular mating connector residing in the side of the wireless telephone. Such a connector would provide stability and preferably position the PC board for proper viewing in the case where an electronic game board/display is used. In other cases, a multi-pin circular connector may be used, as shown in FIG. 6C.  
         [0062]    As shown in FIG. 7, a connector may be positioned on the face of a wireless telephone. Any place where there is available room to house auxiliary connectors would be considered for different applications and designs.  
         [0063]    [0063]FIG. 8 shows a circuit that interfaces with an IRAD in accordance with one embodiment of the present invention. When connector  815  of IRAD  805  is inserted into connector  820  of a communications device, an auxiliary device ID sensor  825  detects a characteristic (e.g., resistance, binary code, voltage, current, or the like) provided by an ID circuit  810  residing within IRAD  805 . The auxiliary device ID sensor  825  may determine whether the characteristic is recognizable and/or valid, or the auxiliary device ID sensor  825  may simply forward the characteristic to a processor  830  in the communications device via path  840  to make that determination. In either case, if the characteristic is recognizable and/or valid, the auxiliary device ID sensor  825  will activate a gateway circuit  835  via path  845  which enables processor  830  to interact with IRAD  805  via gateway circuit  835  and connectors  815 / 820 . Gateway circuit  835  may use one or more of a plurality of switches, diodes, transistors, integrated circuits, and other well-known components to selectively connect processor  830  to connector  820  after the IRAD  805  has been identified. This process prevents the circuitry in the IRAD  805  and/or in processor  830  from being subject to damaging signal voltages, currents, or the like, if the IRAD  805  is incorrectly inserted or if IRAD  805  is not compatible with the processor  830  in the communications device. Thus, connector  820  will be coupled to processor  830  through gateway circuit  835  only after an acceptable IRAD  805  is inserted into connector  820 . Processor  830  will also forward valid auxiliary device ID information to signal generator  850 , which will output the information over a communications link  855  previously established by the communications device. Furthermore, display  860  will present the ID information to confirm to the user that it has recognized the inserted IRAD  805 .  
         [0064]    [0064]FIG. 9 illustrates a flow chart of a method for using an IRAD with communications devices in accordance with the present invention. The method is initiated in step  905 . In step  910 , a user of one of the communications devices either receives a call from a party or places a call to a party to establish a communications link. The user and the party using similar communications devices may carry out conventional communications for any length of time, prior to executing the features of the present invention. At any time desired while the communications link is established, either the user or the party may initiate an auxiliary mode of their communications device by depressing a switch residing on the surface of their communication device (step  915 ). The communications device will then wait for an IRAD to be inserted (step  920 ). Once inserted, the communications device will attempt to determine the identity of the inserted IRAD (step  925 ). If the identity of the inserted IRAD is recognized and considered valid, a processor within the communications device will be coupled to the IRAD (step  930 ). The communication device will then send a signal including the IRAD&#39;s identity over the communications link to the other communications device (step  935 ). The IRAD&#39;s identity will be presented (e.g., displayed, audibly outputted) on each of the communications devices (step  940 ). The method terminates at step  945 .  
         [0065]    [0065]FIG. 10 illustrates terminal circuitry used to implement the present invention. Upon a user depressing a switch that causes a terminal to go into an auxiliary mode when an auxiliary mode activation circuit  1005  sends a signal via path  1010  to a processor  1015 , processor  1010  waits for a signal to be sent by an auxiliary device ID sensor  1020  via path  1025 . Once an IRAD  1030  is inserted into an auxiliary connector such that it couples with gateway circuit  1035  and auxiliary device ID sensor  1020  (also see FIG. 8), the auxiliary device ID sensor  1020  seeks at least one characteristic of the IRAD  1030  and sends a signal to processor  1015  indicating the characteristic and/or whether the characteristic is valid. It should be understood that there may be several gateway circuits  1035  and auxiliary device ID sensors  1020  to handle different types of IRADs  1030  inserted into different auxiliary connectors. It should also be understood that a single auxiliary device ID sensor  1020  and gateway circuit  1035  may be designed such that several IRADs  1030  of different types may be handled simultaneously, or in succession. Processor  1015  will forward valid ID information to instruction signal generator/dialer  1040  which will forward such information over a communications link  1045  (e.g., connected to an antenna, telephone line, or the like). When a communications device on the other end of the communications link sends auxiliary device ID information over the communications link  1045 , it is received and routed to external auxiliary ID detector  1050 . External auxiliary ID detector  1050  checks the validity of the received information and forwards valid information to processor  1015  via path  1055 . Any valid auxiliary device ID information may be forwarded by processor  1015  in a text format via path  1060  and presented on auxiliary device ID display  1065 . The same auxiliary device ID information may be forwarded by processor  1015  in an audible format via path  1070  and outputted by speaker  1075 . If an IRAD  1030  is inserted for the purpose of playing a game over the communications link  1045 , an instruction signal receiver/decoder circuit  1080  is used to receive and decipher game move instructions received from all game players, and forward the deciphered instructions via path  1085  to the processor  1015 . Processor  1015  will operate in conjunction with the IRAD  1030  to facilitate the processing of the game.
