CONTROLLER INCLUDING THE SAME

BACKGROUND [0001] A video game is often played with the help of a video game controller, which usually has a variety of mechanical keys or buttons to command different functions. When a video game controller is operated together with a video game accessory, such as a pistol grip (e.g., gun controller), a moving part of the pistol grip or the like generally physically engages and mechanically moves (e.g., presses) the keys/buttons on the video game controller to command various functions. Such mechanical moving parts on the video game controller can be broken or can wear down over the course of playing video games when using such a video game accessory. By way of example, when a video game controller is used together with a pistol grip, when a trigger on the pistol grip is pulled, a component of the pistol grip is physically moved to mechanically press a button on the video game controller so as to command functions. The video game controller buttons can be damaged through repeated mechanical pressing with hard moving parts of the video game accessory.

DETAILED DESCRIPTION

[0047] In exemplary embodiments according to the present invention, a connector system for video game controllers and/or video game accessories is provided. The connector system includes a female connector and a male connector. The female connector includes a plurality of contacts (or contact plates) for transmitting and/or receiving signals. The male connector for mating with the female connector includes a plurality of contacts (or contact plates) for contacting the contacts (or contact plates) of the female connector to transmit and/or receive the signals. [0048] The signals include one or more of analog or digital directional movement signals, various key/button press signals, power, ground, or motor drive signals (e.g., vibration signals), data or audio signals, etc. The connector system may also include a serial port interface between the female and male connectors. By way of example, by providing (e.g., simulating or replicating) key/button press signals from a video game accessory, key or button pressing of a video game controller can be commanded in the video game controller without actually pressing a key or a button on the video game controller. Similarly, motor drive signals (e.g., vibration signals), directional movement signals, etc. can also be provided to the video game controller and/or the auxiliary video game controller by a video game accessory. By providing control signals (e.g., button press signals) to the video game controller, a need for pressing buttons mechanically on the video game controller may be reduced or eliminated. For example, a video game accessory may have buttons/keys, switches or other mechanical, electromechanical or electrical components for duplication of functions of the buttons/keys or switches on a video game controller. The above components of the video game accessory generate electrical and/or digital signals and send the generated signals to the video game controller rather than mechanically pressing or moving buttons/keys or switches on the video game controller. The video game accessories may include a pistol grip, type pad (e.g., keyboard), steering wheel, arcade stick, various sporting instruments such as baseball bats, golf clubs, etc., swords and other fighting accessories and/or the like.

[0049] The video game controllers may include a WAND™ controller for a Wii® video game console available from Nintendo®, but are not limited thereto. The WAND™ controller is available from Nyko® Technologies, Inc. The auxiliary video game controllers may include a KAMA™ controller for the Wii® video game console, available from Nyko® Technologies, Inc., but are not limited thereto. The video game controllers and auxiliary video game controllers in other embodiments may operate with other video game consoles, such as, for example, Xbox® 360 available from Microsoft® or PS3® available from SONY®, and/or other next generation consoles. [0050] FIG. 1 is a front perspective view of a female connector 10 for a video game controller according to an embodiment of the present invention. The female connector 10 includes a generally cubical case 1 1 and a plurality of pins 12 protruding from a top side of the case 1 1 for electrically connecting electrical contacts of the female connector 10 with electrical circuitry (i.e., electronic circuitry) of a host device (e.g., video game controller, auxiliary video game controller or a video game accessory). [0051] The electrical circuitry may include one or more of a motor for generating vibrations or rumble, a microprocessor or microcontroller for controlling operations of the host device including user interface such as converting button press to electrical signals and light indications, a speaker, a microphone, logic circuitry, communication (e.g., wireless communication) circuitry, motion/orientation sensors, memory and/or the like, as those skilled in the art would appreciate. In FIG. 1, the female connector 10 includes nine pins that are arranged in a 3 x 3 matrix, but the present invention is not limited thereto. The pins may be formed of suitable conductive metal, for example, copper, aluminum or the like. The case 1 1 may be formed of metal such as copper, aluminum, stainless steel or the like. The case includes an insulating material such as plastic, covering at least a portion of its inner surfaces or outer surfaces to prevent shorts.

[0052] The female connector 10 also includes a contact mount 13 in a cavity defined in the case 11, and having a base 14 and a plurality of ribs 15 protruding from the base 14. The base 14 has a substantially flat rectangular shape. The ribs 15 extend parallel to each other, and protrude from both surfaces of the base 14 so as to form a plurality of parallel channels 17 having a same size at both above and below the base 14. In one exemplary embodiment of FIG. 1, the base 14 has four ribs 15 (two ribs on respective edges of the base 14 and two ribs between the edge ribs) located thereon to define three channels on each side of the base 14 (for a total of six channels). The contact mount including the base 14 and the ribs 15 may be made of plastic or other insulating material, and may be formed as a single integrated piece.

[0053] The contact mount 13 has located thereon a plurality of primary contacts (or contact plates) 16 that are electrically coupled to the respective pins 12. Because there are six channels 17 in the embodiment illustrated in FIG. 1 (three on either surface of the base 14), the contact mount 13 can support up to six primary contacts 16. Only two of the primary contacts 16 are shown in FIG. 1 as locations corresponding to four of the primary contacts are hidden from view by other components of the female connector 10. The primary contacts 16 may be formed of suitable conductive metal, such as copper, aluminum or the like. [0054] The female connector 10 also includes a protruding member 18 having a generally rectangular shape and a plurality of secondary contacts (or contact plates) 19 located thereon. The secondary contacts 19 are also electrically connected with the respective pins 12. In one embodiment, when the female connector 10 is used in a video game controller, the primary contacts 16 are used to communicate via the respective pins 12 with an auxiliary video game controller or a video game accessory to transmit/receive such signals as directional movement signals, power, ground and the like. The secondary contacts 19 may be used to communicate via the respective pins 12 with the auxiliary video game controller or the video game accessory to receive key/button press signals, data, serial data, motor drive signals (e.g., vibration signals) and/or the like. The secondary contacts 19 may be formed of suitable conductive metal, such as copper, aluminum or the like.

[0055] While the female connector 10 according to one exemplary embodiment illustrated in FIG. 1 has been described above, the present invention is not limited thereto. For example, the shape of the case, the shape and location of the contact mount, the number of primary contacts and secondary contacts, the number of pins, the functions of each of the contacts and pins, can all be different in other embodiments as those skilled in the art would appreciate. In these other embodiments, the contacts and pins are also used to communicate control and data signals such as analog or digital directional movement signals, motor drive signals, serial data signals, key/button press signals, data or audio signals, and/or power and ground.

[0056] Further, in the female connector 10 and other connectors (e.g., other female and male connectors), primary and secondary contacts (e.g., contacts 16 or 19) are used for making electrical contacts for various different signals. These contact plates for electrical connection help to realize a modularized architecture in which physical contacts between contact plates of interfacing/engaging/mating connectors form an electrical connection. In embodiments of the present invention, such contact plates are used in both male and female connectors to form one or more electrical connections therebetween. [0057] FIG. 2 is a front view of the female connector 10 of FIG. 1. All six of the primary contacts 16 mounted on the contact mount 13 are shown in FIG. 2. FIGs. 3, 4, 5 and 6 are a side view, a rear view, a top view and a bottom view, respectively, of the female connector 10 of FIG. 1.

[0058] FIG. 7 is a front view of a female connector 20 for a video game controller according to another embodiment of the present invention. The female connector 20 is substantially the same as the female connector 10 of FIG. 1 , except that the female connector 20 includes a protruding member 28 on which four secondary contacts (or contact plates) 29 are located, on a case 21. Those skilled in the art would appreciate that the number of pins 12 may be different to account for an additional electrical connection from the secondary contacts 29. Also, those skilled in the art would appreciate that the control and data signals and power and ground carried by the pins 12 and the primary and secondary contacts 16, 29 can include substantially the same signals, power and ground as those carried by the pins 12 and the primary and secondary contacts 16, 19 of the female connector 10 in FIG. 1. The primary and secondary contacts 16, 29 may be formed of suitable conductive metal, such as copper, aluminum or the like. [0059] FIG. 8 is a front view of a female connector 30 for a video game controller according to another embodiment of the present invention. The female connector 30 is substantially the same as the female connector 10 of FIG. 1, except that the female connector 30 includes a protruding member 38 on which five secondary contacts (or contact plates) 39 are located, on a case 31. Those skilled in the art would appreciate that the number of pins 12 may be different to account for additional electrical connections from the secondary contacts 39. Also, those skilled in the art would appreciate that the control and data signals and power and ground carried by the pins 12 and the primary and secondary contacts 16, 39 can include substantially the same signals, power and ground as those carried by the pins 12 and the primary and secondary contacts 16, 19 of the female connector 10 in FIG. 1. The primary and secondary contacts 16, 39 may be formed of suitable conductive metal, such as copper, aluminum or the like. [0060] FIG. 9 is a perspective view of a video game controller 100 including the female connector 10 of FIG. 1. FIG. 10 is a bottom view of the video game controller of FIG. 9, showing the female connector 10 included in the video game controller 100. The video game controller 100 may be any suitable video game controller that can interface with an auxiliary video game controller and/or a video game accessory. By way of example, the video game controller can be a WAND™ controller available from Nyko Technologies, Inc., but the present invention is not limited thereto.

[0061] For example, the control and data signals and power provided to the video game controller 100 can include analog or digital directional movement signals, motor drive signals (e.g., vibration signals), key/various button press signals, serial data signals, audio signals, power, ground and/or the like. In one embodiment, when corresponding key/button signal or signals are received through one or more secondary contacts 19, the video game controller 100 may be commanded as though corresponding one or more keys or buttons have been pressed. In other words, for example, when receiving a signal corresponding to "button 'A' press" through the secondary contacts 19, the video game controller 100 will send signals to the video game console corresponding to pressing of a button A 102. Further, when receiving a signal corresponding to "button 'B' press", through the secondary contacts 19, the video game controller 100 will send signals to the video game console corresponding to pressing of a button B 104.

[0062] The video game controller 100 illustrated in FIG. 9 is a wireless video game controller that can be coupled to the video game console remotely without a wire. However, the present invention is not limited thereto, and the video game controller 100 may be a wired video game controller. Also, while the video game controller 100 can be physically and electrically coupled to an auxiliary video game controller or a video game accessory, the video game controller 100 can alternatively be physically and electrically connected to a dongle (i.e., wireless adapter) that is remotely coupled to an auxiliary video game controller or a video game accessory in a wireless manner.

[0063] While the video game controller 100 in FIGs. 9 and 10 includes the female connector 10 of FIGs. 1-6, the video game controller in other embodiments may alternatively include the female connector 20 of FIG. 7, the female connector 30 of FIG. 8 or a female connector 10' of FIG. 17 described below. Alternatively, the video game controller in other embodiments may include a male connector that is a mating connector to one of the female connectors 10, 20, 30 or 10', which male connector is to be described below. In still other embodiments, the video game controller may use a female or male connector that has different shapes and/or different number of pins and contacts without departing from the spirit or scope of the present invention.

[0064] FIG. 11 is a front perspective view of a video game accessory (or video game controller accessory) 200 including a male connector 208 for mating with the female connector 10 on the video game controller 100 of FIG. 9. FIG. 12 is a front view of the video game accessory 200 of FIG. 11.

The trigger 202 is configured to be pulled by a user to give a shooting command control signal to the video game controller 100. By way of example, in one embodiment, when the trigger 202 is pulled, the video game accessory 200 sends a control signal corresponding to pressing of the 'B' button 104 on the video game controller 100, to the video game controller 100. [0065] The video game accessory 200 also includes a male connector 208 for physically and electrically coupling to the female connector 10 of the video game controller 100. The male connector 208 has formed thereon a plurality of primary contacts (or contact plates) 210 for electrically coupling with the primary contacts 16 of the female connector 10. In one embodiment, three primary contacts 210 are formed at each of both top and bottom inner surfaces of the male connector 208 to electrically couple with the six primary contacts 16 of the female connector 10.

[0066] The male connector 208 also includes a plurality of secondary electrical contacts 212. The electrical contacts 212 are spring loaded to press on the secondary contacts 19 of the female connector 10 for sufficient electrical connection. In one embodiment, the male connector 208 includes three secondary contacts 212 to electrically couple with the three secondary contacts 19 in the video game controller 100 of FIG. 9. In other embodiments, the number of primary and/or secondary contacts may be different to electrically contact the primary and secondary contacts 16, 19 of FIG. 9. The primary and secondary contacts 210, 212 may be formed of suitable conductive metal, such as copper, aluminum or the like. [0067] In operation, for example, the primary contacts 210 may receive power, ground and other signals from the video game controller 100 through the primary contacts 16. The secondary contacts 212 are used to transmit control signals to the video game controller 100.

While the video game accessory 400 includes only six primary contacts 210 and the three secondary contacts 212, in other embodiments, the number of primary and/or secondary contacts may be different to correspond to the number of primary /secondary contacts in the corresponding female connector. [0077] FIG. 17 is a bottom perspective view of a video game controller 100' including a female connector 10' of another embodiment according to the present invention. The female connector 10' of the video game controller 100' is substantially the same as the female connector 10 of the video game controller 100, except that the female connector 10' includes a pair of additional contacts (or contact plates) 40 that are used to receive additional control signals from an external device, such as a video game accessory or an auxiliary video game controller. As can be seen in FIG. 17, the additional contacts 40 are formed on an insulated inner surface of the case 11, and may be used to receive control signals for driving a motor (e.g., rumble or vibration signal). The contacts 40 may be formed of suitable conductive metal such as aluminum or copper, for example. [0078] FIG. 18 is a perspective view of a male connector 208' configured to mate with the female connector 10' on the video game controller 100' of FIG. 17. The male connector 208' has substantially the same configuration as the male connector 208 of FIG. 11 , for example, except that it includes additional contacts (or contact plates) 50 for electrically coupling with the contacts 40 to provide control signals to the video game controller 100'. The contacts 50 may be formed of suitable conductive metal such as aluminum or copper, for example. [0079] FIG. 19 is a block diagram of a video game accessory 504 coupled to a video game controller 500 and an auxiliary video game controller 506 according to another embodiment of the present invention. The video game accessory 504 may be a pistol grip similar to the video game accessories depicted in FIGs. 1 1 and 13, but may additionally have a mount support for mounting the auxiliary video game controller 506 in addition to the video game controller 500 that may be substantially similar to the video game controller 100 of FIG. 9. [0080] The video game controller 500 may be substantially similar to the video game controller 100 of FIG. 9, and may be a WAND controller available from Nyko Technologies, Inc. The auxiliary video game controller 506 may be a KAMA controller with rumble available from Nyko Technologies, Inc. In one embodiment, the KAMA controller with rumble is wired; in other embodiments, the KAMA controller with rumble may be configured to communicate wirelessly with the video game controller 500 and/or the video game accessory 504.

[0081] The video game accessory 504 provides a key/button press signal, and a motor drive signal to electric circuitry (i.e., electronic circuitry 502) of the video game controller 500. The electrical circuitry 502 may include one or more of a motor for generating vibrations or rumble, a microprocessor or microcontroller for controlling operations of the video game controller 500 including user interface such as converting button press to electrical signals and light indications, a speaker, a microphone, logic circuitry, communication (e.g., wireless communication) circuitry, motion/orientation sensors, memory and/or the like, as those skilled in the art would appreciate.

[0082] By way of example, the key/button press signal in one embodiment commands the electric circuitry 502 in the video game controller 500 to initiate operation as though one of the keys/buttons (e.g., 'A' or 'B' key or button) has been pressed. Here, the key/button press signal may be connected in parallel to A and B keys/buttons. In other words, these signals duplicate or simulate the functions of the A and B keys/buttons. Further, the motor drive signal causes the motor in the electric circuitry 502 to operate to generate vibrations. The motor drive signal may originate from the video game controller 500 and may be a synchronizing rumble signal to the video game accessory 504 and the auxiliary video game controller 506. Here, the motor drive signal can be provided to the video game controller 500 by the video game accessory 504, but it is not required. For example, in an exemplary embodiment, the video game accessory 504 (e.g., a gun grip) can have a motor for vibrations that can be operated by activating a switch (e.g., pressing a button or pulling a trigger). The video game accessory 504 can also send a motor drive signal to the video game controller 500 to drive the motor for vibrations in the video game controller 500. [0083] The video game controller 500 and the video game accessory 504 also have an Inter-Integrated Circuit (I C) data bus interface therebetween in one embodiment. The I ² C data bus has three signal wires for Serial Data (SDA), Serial Clock (SCL) and SIG VDD signals. SDA is a data signal, SCL is synchronization clock, and the SIG VDD is peripheral equipment detect signal. The video game accessory 504 also communicates with the auxiliary video game controller 506 over an I ² C data bus. The video game accessory 504 in one embodiment supplies power (e.g., 3.3V DC power) to the auxiliary video game controller 506 to electrical circuitry therein and to the motor drive circuit 508. The power may originate from the video game controller 500 or from the video game accessory 504. For example, the video game controller 500 may provide power to the video game accessory 504. [0084] FIG. 20 is a block diagram of the video game controller 500 coupled to the auxiliary video game controller 506 according to another embodiment of the present invention. The system depicted in FIG. 20 is substantially similar to the one depicted in FIG. 19, except that the video game controller 500 and the auxiliary video game controller 506 operate together without a video game accessory. The video game controller 500 and the auxiliary video game controller 506 communicate with each other over an I ² C data bus. The video game controller 500 provides power (e.g., 3.3V DC power) to the auxiliary video game controller 506. The video game controller 500 also provides the motor drive signal to the motor drive circuit 508 in the auxiliary video game controller 506. [0085] FIG. 21 is a perspective view and signal description of a female connector (or female plug) 600 of a video game controller according to another embodiment of the present invention. The video game controller may be a WAND controller. It can be seen in FIG. 21 that the female connector 600 includes a plurality of pins: 1) GND, 2) KEY A, 3) GND, 4) SDA, 5) GND, 6) NC (not connected), 7) SIG VDD, 8) KEY B, 9) MOTO DEV, 10) VDC 3 V and 11) SCL. The VDC 3 V and GND pins are for providing power and ground to an external devices (e.g., an auxiliary video game controller). The SDA, SCL and SIG VDD pins are for an I ² C data bus interface, wherein SDA is data signal, SCL is synchronizing clock, and SIG VDD is peripheral equipment detect signal. KEY A and KEY B are for receiving 'A' and 'B' button press signals. The MOTO DEV pin is for providing a motor drive signal. The female connector 600 also includes secondary contacts for KEY A and KEY B signals and GND. The secondary contacts KEY A and KEY B are for receiving button press signals to be transmitted to the respective pins. [0086] In one embodiment, the I ² C data bus interface sends and receives bi-directional signals, the KEY A,B signals are for receiving button press signal input, and the motor drive signal is an output signal. Further, in a particular embodiment, the power of VDC 3 V and GND are provided as an output by the video game controller. As indicated by the signal directions (bi-directional arrows) in FIG. 21, however, one or more of the I ² C data bus signals, KEY A,B signals, Motor drive signals and Power can be provided in a single direction and/or bi-directional manner (i.e., can receive and/or transmit over the same contacts or contact plates) in other embodiments, depending on the operation mode and/or configuration of the video game controller and the video game accessory and/or the auxiliary video game controller coupled to the video game controller. [0087] FIG. 22 is a perspective view and signal description of a male connector (or male plug) 700 of a video game accessory according to another embodiment of the present invention. The video game accessory may be a gun controller or a pistol grip. The male connector 700, for example, may be substantially similar to the male connector 208' of FIG. 20. The male connector 700 has secondary contacts (pins) for outputting KEY A, KEY B and GND signals. The male connector 700 also includes pins SDA, SCL and SIG VDD for an I ² C data bus interface. The male connector 700 also includes GND and VDC 3V contacts for receiving power, and also has a non-connected (NC) pin. The connector 700 also sends out GND and MOTO DEV for sending motor signals. As indicated by the signal directions (bi-directional arrows) in FIG. 22, one or more of the I ² C data bus signals, KEY A,B signals, Motor drive signals and Power can be provided in a single direction and/or bi-directional manner (i.e., can receive and/or transmit over the same contacts or contact plates) in other embodiments, depending on the operation mode and/or configuration of the video game accessory and the video game controller and/or the auxiliary video game controller coupled to the video game accessory.

[0088] FIG. 23 is a perspective view and signal description of a male connector (or male plug) of an auxiliary video game controller 800 according to another embodiment of the present invention. The auxiliary video game controller 800 may be a KAMA controller with rumble. The male connector 800, for example, may be substantially similar to the male connector 208' of FIG. 20.
