Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to electronic devices. More particularly, the present invention relates to electronic devices with full fold out keyboard and/or display.  
       BACKGROUND OF THE INVENTION  
       [0002]     A cellular telephone is designed to give the user maximum freedom of movement while using a telephone. A cellular telephone uses radio signals to communicate between the “cell phone” and a base station, via an antenna. The served area is divided into cells, something like a honeycomb, and an antenna is placed within each cell and connected by telephone lines to one exchange devoted to cellular-telephone calls. This exchange connects cellular telephones to one another and transfers the call to a regular exchange, public switched telephone network, if the call is between a cellular telephone and a non-cellular telephone. The special cellular exchange, through computer control, selects the antenna closest to the telephone when service is requested. As the telephone roams, the exchange automatically determines when to change the serving cell based on the power of the radio signal received simultaneously at adjacent sites. This change occurs without interrupting conversation. Practical power considerations limit the distance between the telephone and the nearest cellular antenna, and since cellular phones use radio signals, it is possible for unauthorized people to access communications carried out over cellular phones. One of the reasons why digital cell phones have gained in popularity, besides being able to access the Internet, is because their radio signals are harder to intercept and decode.  
         [0003]     In order to input information into a cellular phone, it is desirable to have a keyboard. However, with the limited size of cellular phones, it is difficult to place a keyboard and number dial pad on a cellular phone. Additionally, should a user want to play video games using the cellular phone, adding a game pad along with the number dial pad in the cellular phone is even more difficult.  
         [0004]     U.S. Pat. No. 5,337,346 issued to Uchikura describes an electronic device with a foldable keyboard. However, the keyboard is only used for inputting data to the device while in an electronic notebook mode. Uchikura does not allow data that is entered via the keyboard to be transmitted outside the device. Currently there are about 30 billion text messages sent every month via wireless phones. This number is expected to double in the future. As mobile phones and computers converge towards unified handheld communication and computing devices, text messaging is becoming one of many ways in which text entry on handheld devices will be employed. Text entry is an integral part of the way users interact with computers in general and the Internet in particular. Simple text entry is required to query search engines, to send email or instant messages and to enter commands. The inadequacy of currently used methods for entering text is the major obstacle inhibiting the growth of a wireless web and other applications, such as, Microsoft&#39;s Pocket Word and Pocket Excel. A numeric keypad will always be a poor device for entering strings of text data. A QWERTY-style keyboard on a mobile device is needed to provide an easy to use text entry solution. Such a device will help the mobile Internet achieve its full commercial potential.  
         [0005]     Current gaming devices with handsets that fold bring the primary display on top of the control pad area. The result is that the primary design display is not visible when the device is folded. Other gaming devices do not have folding keyboard designs along with the gaming control pad or typically map 12-key buttons into gaming buttons rather than providing separate independent gaming controls.  
         [0006]     Thus, there exists a need for an electronic device having a number pad for telephone functions, a full keyboard for input of text entries, and/or a game control keyboard to allow a user to play video games.

         [0016]     Embodiments of the present invention refer to an electronic device having a number pad for telephone functions, a full keyboard for input of text entries and/or a game control keyboard to allow a user to play games. The embodiments of the present invention may be used in cellular phones, cordless phones, and any portable telephone. Referring now to  FIG. 1 , an illustration of a telephone in accordance with an embodiment of the present invention. The telephone, generally numbered  10 , is illustrated in a first open position with the display screen  12  folded out from the input member  100 . The input member  100  consists of the numberic dial pad  14  and a keyboard. The keyboard is hidden underneath the fold-out numeric dial pad  14 . The telephone  10  has a fold-out display screen  12  to provide visual output to the user. The visual output may be text, graphical information, icons, pictures, and/or videos.  
         [0017]     Function keys  16   a ,  16   b ,  16   c ,  16   n  (where n is an integer) allow a user to control the basic functions of the telephone  10 . Function keys  16   a ,  16   b ,  16   c ,  16   n  may allow a user to select options on a menu, activate various programs such as telephone and communication enabling programs. Examples of function keys may be “Talk”, “Menu”, “Cancel”, “End”, and/or arrow buttons. Although  FIG. 1  illustrates four function keys, the number of function keys may vary and is not intended to be limiting. Additionally, the illustrated location of the function keys is not intended to be limiting. By way of example, the function keys may be positioned on the sides or top of the telephone  10 .  
         [0018]     The numeric dial pad  14  may be used as a traditional cellular or wire line telephone number pad. As illustrated, the number pad is a 12-key number dial pad with the numbers 0-9 on a 3×4 keypad matrix with the star symbol, zero, and pound symbol on the bottom row. The three or four letters represented on the 12-key numeric dial pad  14  on 0 and 2-9 may also be included for short text entries. The number dial pad  14  may be movably attached to the display screen  12  such that the display screen  12  may be folded upwards in the direction of arrow  26  to reveal the number dial pad  14 . The number dial pad  14  may be movably attached to the display screen  12  by any means such as a hinge  24 .  
         [0019]     The telephone  10  may have a microphone  18  to accept voice data from the user. A speaker  20  provides audio output to the user. However, the number of microphones  18  and/or speakers  20  may vary in other embodiments of the present invention. For example, other embodiments of the present invention may utilize earphones and/or headsets for a “hands free” mode of operating. An antenna  22  may be used to provide for communication between the telephone  10  and a cellular telephone base station. A camera (not shown) may also be coupled to the telephone  10 .  
         [0020]      FIGS. 2A, 2B , and  2 C illustrate an embodiment of the present invention in an open keyboard position. The keyboard, as illustrated in  FIG. 1 , was underneath the number dial pad  14 .  FIGS. 2A, 2B , and  2 C illustrate the fold-out number dial pad  14  folded out sideways in the direction of arrow  50  to reveal the keyboard  30 . Thus, an embodiment of the invention provides for a double flip telephone. The first flip, folding the display screen  12  upwards, reveals the display screen  12  and number dial pad  14 . A second flip, folding the number dial pad  14  sideways, reveals the keyboard  30 .  
         [0021]     As illustrated in  FIG. 2A , the keyboard may be a qwerty keyboard  30  having a space key  34 , return key  36 , and may have mathematical function keys  38 . However, any other keyboard may be used. As illustrated in  FIG. 2B , the keyboard may be a game pad keyboard  32 . The game pad keyboard  32  may have various function keys such as trigger buttons  40   a ,  40   b , a directional pad  42 , programmable action buttons  44   a ,  44   b ,  44   c ,  44   n  (where n is an integer), and slider/throttle control  46 . The type of function keys may vary depending on the game pad keyboard and the illustrations of the various keys is not intended to be limiting.  
         [0022]     The number dial pad may fold out sideways either to the right as illustrated in  FIG. 2B  or to the left as illustrated in  FIG. 2C . Thus, the direction of the fold-out of the number pad is not intended to be limiting. The number pad may be movably attached to the keyboard by any means such as a hinge  28 .  
         [0023]     As illustrated in  FIG. 2C , an embodiment of the present invention may be used with only one flip. The display screen  12  and number dial pad  32  may comprise of a single unit with only the number dial pad  14  folding out to reveal the game pad keyboard  32 .  
         [0024]      FIGS. 3A and 3B  illustrate a side view in accordance with an embodiment of the present invention.  FIG. 3A  illustrates the side view of an embodiment of the present invention with the number pad  14  in a closed position.  FIG. 3A  illustrates the side view of an embodiment of the present invention with the number pad  14  in an open position such that the keyboard  30  is therefore revealed.  
         [0025]      FIG. 4  is a block diagram of a method in accordance with an embodiment of the present invention. If the telephone is off, the user must turn the telephone on at  60  using an on/off function key. When the telephone is turned on or awakened from a power saving mode, the telephone determines whether the keyboard is in an open position at  62 . The position of the keyboard will determine the menu that will be displayed. If the keyboard is in a closed position, a telephone menu may be displayed at  64 . However, if the keyboard is in an open position, a second menu may be displayed depending on the type of keyboard at  66 . If the keyboard is a game pad keyboard, then the second menu may be a game menu at  70 . However, if the keyboard is a qwerty keyboard, then the second menu may be a text menu at  68  allowing a user to send electronic mail, access the internet, and perform other similar functions.  
         [0026]     Wireless hardware and firmware capable of supporting wireless communications protocols such as CDMA, GSM, GPRS, 802.11b, Bluetooth, etc. may be included in the telephone as well as IrDa, USB, digital camera, memory expansion, and the like. Additionally, microprocessors and memory for running various software applications, wireless and web browsers, electronic mail client software, PDA software may be included in the telephone. However, to prevent obfuscation or confusion of the present invention, the hardware and software will not be further discussed as it is well known to those of ordinary skill in the art.  
         [0027]     While embodiments and applications of this invention have been shown and described, it would be apparent to those skilled in the art having the benefit of this disclosure that many more modifications than mentioned above are possible without departing from the inventive concepts herein. The invention, therefore, is not to be restricted except in the spirit of the appended claims.
