       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The present invention relates to video game controllers and more specifically to an integrated controller and video display device for both controlling and displaying an interactive video game.  
           [0004]    2. Description of the Related Art  
           [0005]    Computer video games are well known in the art. Such devices range from small hand held all-in-one units, to larger stand-alone units which interact with stand alone controllers and stand alone video display devices. Small hand held devices are very portable. However, the graphics and sophistication game play are substantially inferior to stand alone units due limited processing power and associated peripherals. For more sophisticated play, stand alone computer units provide tremendous processing power and work with associated peripheral devices, such as a remote controller and television display in an attempt to bring the player a more dramatic gaming experience to that of hand held devices. One such stand-alone device is disclosed in U.S. Pat. No. 6,422,943 which is hereby incorporated by reference. These devices are widely available on the market and are well know in the art. FIGS. 8-9 depict such a conventional stand-alone computer video gaming device. A central stand-alone console contains all the essential processing components to run a computer game. A controller is connected to communicate operation control commands from a user. A separate display is connected to the gaming deice to display interactive video gaming images. As previously mentioned, this conventional arrangement is well known in the art.  
           [0006]    With the tremendous commercial success of stand alone computer gaming systems, and entire peripheral market has emerged ranging from advanced video controllers, joysticks, steering wheel devices for racing games, multi-tap controllers, vibrating controllers, video stands, audio systems and the like. Programmable controllers are also available which allow a user to customize the operation of control buttons and to even store and retrieved such customized arrangements. One such device is disclosed in U.S. Pat. No. 5,759,100 which provides an LCDP display interface to facilitate programming the controller and is hereby incorporated herein by reference. The display device  18  of the &#39;100 device is limited to an alphanumeric display in response to manual manipulation of program keys.  
           [0007]    Stand alone computer gaming devices all require the use of a display device such as a television as shown in FIGS. 8-9. These devices are specifically suited for home use and do not lend them selves to portable use or in a manner which is intimate to the user. Hand held gaming systems incorporate an all-in-one processor, display and controller into a single to facilitate portability and intimate interaction with the game. One such system is disclosed in U.S. Pat. No. 5,184,830 and is incorporated herein by reference. However, as previously mentioned such systems do not provide the sophistication level of game play or graphics that stand alone systems can provide. Heretofore, the prior art has failed to integrate a display device into a controller for interaction with stand-alone computer game device.  
         SUMMARY OF THE INVENTION  
         [0008]    The present invention is directed to a computer game controller with integrated video display device. The controller has a video device mounted, affixed or otherwise interconnected with a hand held controller. A communication system connects the controller with a stand-alone computer game device. The communication system establishes a communication link to facilitate the transmission of both command signals and audio/video signals between the controller and computer device. The integrated controller and video display device of the present invention provides two-way interaction with the stand-alone computer device within a single accessory device. The integrated controller and video display device may also incorporate a speaker or headphone jack to deliver audio stimulation.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0027]    [0027]FIG. 1 depicts a video game controller with integrated video display  1  according to one embodiment of the present invention. A hand held unit  3  ergonomically formed to be held by a hand(s) of a user. The hand held unit  3  includes a plurality of operating members for manipulation of the users hand to facilitate interaction with game play. The controller may be the programmable type, include a vibratory member for heightened game play as well as lighted buttons etc. A communication cable  7 , details of which will be explained later, is also provided to facilitate communication with a stand-alone computer gaming device. Such controllers and operating members are well known and within the knowledge of one of ordinary skill in the art.  
         [0028]    The video game controller further incorporates an integrated display device  9 . Preferably the display device is a color LCD (Liquid Crystal Display) type with associated driver circuitry to facilitate display of a video signal. Preferably the driver and other associated circuitry are contained within the body of the hand held unit  3 . It is understood that small high resolution color LCD displays with associated circuitry are readily available and are known to one of ordinary skill in the art. Small high-resolution LCD displays have been incorporated into small hand held color televisions, video recorders, digital cameras, and other devices. Such readily available off the shelf LCD displays and associated circuitry can easily fit within the confines of the hand held unit  3  as contemplated by the present invention. In the embodiment of FIG. 1, a 3.2 inch LCD video display having a conventional 4:3 aspect ratio is be integrally molded into the front portion of the hand held unit  3  to form an integral one piece device. Off course both smaller and larger LCD display systems may be employed. The LCD display is positioned to be readily visible to the user when holding the hand held unit. The communication cable  7  contains both a conventional bundle for communicating operating control commands in response to manipulation of the operating members by the user and a separate bundle carrying video signals to the video circuitry of the LCD display.  
         [0029]    State of the art stand alone computer gaming platforms also transmit low DC voltage across the communication bundle to power circuitry within the controller, power vibration devices, etc. Currently available LCDs do not consume much power and it is preferred to use the incoming low voltage DC source from the computer gaming system to rung the LCD display. According to the present invention, the console of the gaming platform is modified to provide a single connection point to connect the communication cable  7  including conventional control command communication bundle, a voltage source line and a video cable integrated into a single cable. The details of such a connection will be explained later. However, if such additional voltage is necessary, the hand held unit may incorporate a battery or other connection directly to an external voltage source.  
         [0030]    [0030]FIGS. 2-3 represents an alternate embodiment of the present invention. A cover  11  is pivotally mounted above the LCD display screen  9 . Raised hinged members  13  may be simply formed into the molding of the hand held unit  3  for engagement with a pintle member  14  integrally formed in the cover. The cover  11  then may be installed simply by snap fitting the pintle  14  members into the hinge member  13 . Preferably the cover member  11  is made of plastic or other material similar to the construction of the hand held body  3 . FIG. 2 represents the cover in a closed position covering the LCD display  9 . FIG. 3 depicts the cover  11  in an open position visually exposing the LCD display  9 .  
         [0031]    [0031]FIGS. 4-7 represents another alternate embodiment of the present invention having a removable display device  109 . By allowing the removal of the display screen, the controller portion  103  can be utilized with a conventional stand-alone display device. The removable display device is preferably equipped with a pass through device  120  to facilitate a single connection point to the communication cable  107 . The use of a pass through device  120  for the selective removal of the display device  109  facilitates the use of a common communication cable  7 ,  107  for both embodiments where the display device  9  is unitarily formed with the hand held body  3  and the controller  103  having a removable display device  109 . To achieve this, both the integral display device  9  of FIG. 1 and the removable display device  109  of FIGS. 4-5 include a connection opening  130 . The connection opening has a first port  131  with a female mounting arrangement and pinout to receive a male plug having corresponding pins to operatively form a connection of a control command communication bundle (such as those found within conventional controller cables of conventional gaming platforms such as the Playstation II by Sony). The connection opening  130  further has a video  133  and audio  135  female RCA jacks (or other known connections) to form a connection with an audio and video signal bundle for the controller embodiment of FIG. 1. (It is noted that for the controller of FIG. 4-5, not such audio/video connections are necessary, as those communication signals will be directly ported to the LCD display and audio device within the removable device  109 .) Alternately, a voltage source pinout jack  137  may exist to establish a connection to a voltage source flowing from the game console in additional to any voltage available through the first port  131 .  
         [0032]    The pass through portion  120  has an oval shaped stem  121  projecting from a central portion  125  to matingly fit within the opening  130 . As can be seen in FIG. 7 a , the oval shaped stem includes corresponding male connections (not labeled) to establish a connection with corresponding portions of the controller. On the opposite side of the central portion  125 , a female connection opening is formed identical to opening  130  of the controller with associated connections portions identical to portions  131 ,  133 ,  135  and  137  of the controller. An electrical connection between the male and female pinout connections of the pass through device  120  is simply contained within the central body  125 . The pass through device further simply routes the audio/video signals directly to the associated devices within removable display  109 . Thus as can be readily seen in FIG. 7, the communication cable  107  may be either connected to the pass through device  120  of removable display  109  or directly to the opening  130  of the hand held unit  3 . It is to be understood that the shape of stem  121  need not be oval. However, it is preferred to employ a non-circular shape to prevent any rotational movement between the controller and associated pass through device or cable bundle.  
         [0033]    The pass-through device  120  is preferably pivotally mounted to the LCD display screen  109  to selectively customized viewing for the user. The pivotal connection further provides the ability to fold down the LCD display screen  109  on top of the controller  103 .  
         [0034]    [0034]FIGS. 10-11 respectively depict schematic and plan views of the integrated video controller and display device  3  with a stand-alone computer gaming system  90 . As can bee seen a single communication cable  7  incorporates both a video signal cable and a conventional control command bundle. In order to provide a single point connection to the stand-alone game system  90  the console of the game platform incorporates a connection portion a pinout substantially identical to the opening  130  and connection pinout portions  133 ,  135  and  137  of the controller  3 . Such an arrangement facilitates the use of a single communication cable  7 / 107  having identical male pinouts and mounting portions on either end. However, it is to be understood that male/female portions may be interchanges so long corresponding portions of associated pieces match to complete the communication between the stand alone gaming platform  90  and either the controller of FIG. 1 or the pass through device  120  of FIG. 7.  
         [0035]    In order to enable the use of the video game controller  1  and integrated display device of the present invention with conventional stand-alone gaming platforms  190 , an adapter cable  50  may be utilized. As can be seen in FIG. 12, the adapter  50  has a first end which mates with the communication cable  7 , 107 . The adapter  50  serves to split the conventional command bundles and other bundles to facilitate separate connection to a controller interface of the conventional  190  device and the video/audio outputs.  
         [0036]    While the present invention has been preferably described for connection of the communication cable  7 / 107  directly to the stand alone game console  90  through a single connection port, the controller  1 , and integrated video display can be used with stand alone gaming platform  190  having separate controller port(s) and video port(s). As previously discussed, FIG. 12 depicts and alternate embodiment of the present invention. In order to facilitate connection to a conventional game platform  190 , the adaptor  50  acts as a pass-through device for operation command to connect to the conventional controller port of the game console. The pass-through device bifurcates the command data bundle from audio, video or other lines such as a voltage source line into separate cables. As can be seen in FIG. 12, a video cable  51  runs to the rear of the console to connect with a video output jack  71 . The video output jack can be a conventional single line RCA jack, S-video or three-line connection as is well known in the art. A second audio line  53  extends to stereo audio output jacks  63 ,  64 . The audio may be a mono or stereo line and is connected to a conventional RCA audio jack or other suitable interface. The pass-through portion of the adaptor  50  simply mirrors that of command port  131  (see FIG. 6) with a female mounting arrangement and pinout to receive the male plug of the communication cable having corresponding pins to operatively form a connection of a control command communication bundle and audio/video jacks. Within adaptor  50  the control command bundle splits off from the audio/video bundle and the adaptor  50  has a male end simulating the male connection portion of a conventional controller port connection similar to the upper portion of the pas through device  121  of FIG. 7. The audio/video cables simply extend from adaptor  50  to the rear portion of the console and connect to respective ports as is conventional in the art.  
         [0037]    The controller/integrated display  1  further may contain speakers  81  within the controller as shown in FIG. 12 to provide audio as generated by the gaming circuitry.  
         [0038]    [0038]FIG. 13 depicts a controller  201  with a display device  209  pivotally secured to the hand held unit  203 . A display device  201  is simply secured to the hand held unit  203  with a simple hinge device  265  with corresponding portions integrally formed with the body of each of the hand held unit  203  and the display device  209 . The display device  209  may then be pivoted towards and away from a user handling the controller  201  to optimize viewing comfort. Alternately, the display device  209  may connected via a ball and socket connection to facilitate an additional degree of freedom to allow both pivotal and rotational movement of the display device  209  relative to the hand held unit  201 . A stop member is preferably integrated into the pivotal connection  265  to limit the extent of rotation. The particular structure of the pivotal connection  265  is not critical to the present invention so long as the display device  209  can move relative to the hand held unit  203  without disturbing communication between the LCD display the circuitry within the hand held unit  203 . In this embodiment, the communication cable may extend directly from the hand held unit  203  to the stand alone gaming device and a smaller communication cable simply extends through the pivotal connection  265  to interconnect the display device  209  and the circuitry contained within the hand held unit  203 .  
         [0039]    [0039]FIG. 14 represents an alternate embodiment. The integrated controller  301  includes a retractable display device  309 . In the present embodiment, the display device  309  preferable slides in and out of the hand held unit  303 . The sides of the LCD display  109  may be disposed within a channel track integrally formed into the body of the hand held unit  303 . A stop member may simply be formed on the inside edge of the display device  109  to prevent the display device from dislodging from the hand held unit  203 . Here again, the specific structure of the retractable connection between the display device  309  and the hand held unit  303  is not crucial so long as the display device is permitted to be displaced without effecting the ability to display video images. The display device  309  may further be pivotally connected to a portion that slides within the channels formed in the hand held unit  303  to provide additional positional control of the display device  309  relative to the hand held unit  303 . Such an arrangement not only provides customized positional viewing control but also facilitates protection of the display device  309  when not in use.  
         [0040]    [0040]FIGS. 15-16 represents yet another embodiment of the present invention. According to the present embodiment, the display device  409  is pivotally connected to a top portion of the hand held unit  403 . Such an arrangement facilitates a flip up display device. When the display device is on the closed position, the back of the display device  409  serves as a cover to protect the LCD display. The display device  409  may simply flip up to an optimized viewing position during use. The display device  409  may simply be pivotally connected to the top potion of the hand held unit  403 . Raised hinged members  413  may be simply formed into the molding of the hand held unit  403  for engagement with a pintle member  414  integrally formed display device. A communication cable may simply extend from the display device  409  to within the circuitry within the hand held unit  403 . Preferably the body of the display device is made of plastic or other material similar to the construction of the hand held body  403  and suitable for integrally forming the respective pintle and hinge members unitarily with their associated component.  
         [0041]    While the foregoing invention has been shown and described with reference to a preferred embodiment, it will be understood by those possessing skill in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. For example, FIG. 17 contemplates a wireless embodiment where the integrated controller  501  communicates with the stand-alone console  590  via radio waves. A transmitter  550  may simply be inserted into a controller port and further connected to audio/video outputs of the console. Wireless controllers are known in the art. However, such controllers are limited to communicating operational data between the stand-alone console and controller device. The transmitter of the present invention transmits not only operational commands between the controller and stand-alone game console, but video and audio signals as well. Thus the integrated controller is equipped with a receiver to receive such signals. In this embodiment, the hand held unit is equipped with batteries to provide sufficient power to run the display device  509  and associated circuitry within the hand held unit. The associated components are then neatly arranged within the confines of the hand held unit to provide a complete package to interact with the gaming processor of the stand-alone unit  590 . Such an arrangement will allow multiple players to compete without having to view a common screen. In fact, two players do not even have to be within the same room to engage in a common game adventure. It has been demonstrated that communication within the range of 1.2-2.4 Gigahertz is sufficient to transmit the necessary command controls and audio/video data to facilitate a wireless remote interaction between the stand-alone computer game console  590  and the integrated controller and video display  501  of the present invention.
