Abstract

A method and apparatus are provided for creating a personal area network with a wireless keyboard, comprising generating a text message on a keyboard integrated display to prompt a user to enter a password, determining all available personal area network devices and displaying a subset of the available personal area network devices based upon access permissions associated with the password. Generally, the wireless keyboard includes logic for generating prompts to a user to create a master password and user passwords with defined access privileges. Moreover, a user, by utilizing the display, may select alternate or additional devices with which to couple. In one embodiment, the wireless keyboard is further operable to send and receive text messages with a cell phone which are further propagated through a cellular network using legacy text message protocols.

Claims

1. A method within a wireless keyboard for integrating the wireless keyboard with one of a wireless personal area network or a wireless local area network, comprising:

operating in a wireless interface disabled mode until a valid access code is typed onto a keypad of the wireless keyboard;

receiving a sequence of key entries made upon the wireless keyboard;

comparing the sequence of key entries to a specified access code;

if the sequence of key entries match the specified access code, enabling a wireless interface to operate in a wireless interface enabled mode; and

establishing a master/slave relationship with at least one other wireless device.

2. The method of claim 1 further including generating a display on a display integrated into the wireless keyboard to prompt a user to enter the valid access code.

3. The method of claim 2 including defining a password for a keyboard master after determining that the valid access code has been entered by prompting the user on the display to create a keyboard master password.

4. The method of claim 2 further including, after the wireless interface is enabled, displaying at least one wireless device with which a personal area network may be established.

5. The method of claim 4 further including transmitting an access request to a selected wireless device.

6. The method of claim 5 further including prompting the user to enter a password to gain access to a selected wireless device and transmitting the entered password to the selected wireless device.

7. The method of claim 6 further including receiving an indication that a personal area network has been established with the wireless keyboard whereby the wireless device is operable to establish the personal area network only upon receiving a valid password.

8. The method of claim 7 further including storing an indication that a personal area network was established between the wireless keyboard and the wireless device.

9. The method of claim 8 further including wirelessly detecting that the wireless device is present and, based upon determining that the indication has been stored, establishing the personal area network between the wireless keyboard and the wireless device without prompting, on the integrated wireless keyboard display, the user to enter a password to establish the personal area network with the wireless device.

10. A method for integrating a wireless keyboard with one of a wireless personal area network or a wireless local area network, comprising:

generating a display on a display integrated into the wireless keyboard to prompt a user to enter a valid access code wherein the display is generated solely by the wireless keyboard;

receiving a sequence of key entries;

comparing the sequence of key entries to a specified access code;

if the sequence of key entries match the specified access code, defining a password for a keyboard master after determining that the valid access code has been entered by prompting the user on the display to create a keyboard master password;

enabling a wireless interface of the wireless keyboard to operate in a wireless interface enabled mode; and

establishing a master/slave relationship with at least one other wireless device.

11. The method of claim 10 further including, for the at least one other wireless device, prompting the user of the keyboard master password to create at least one password for access to the at least one other wireless device.

12. The method of claim 11 further including prompting the user of the keyboard master password to create a plurality of passwords and corresponding access levels for a plurality of other wireless devices.

13. The method of claim 12 wherein each created password of the plurality of passwords has an associated list of wireless devices of the plurality of other wireless devices for which access is allowed.

14. A wireless keyboard, comprising:

an integrated display for displaying messages and status indications to a user;

a wireless front end for transmitting and receiving communication signals with one of an access point or a Bluetooth enabled wireless device; and

a processor with associated logic coupled to the integrated display, the logic for generating the messages and status indications and for receiving in-going signals from the wireless front end and for transmitting out-going signal to the wireless front end.

15. The wireless keyboard of claim 14 wherein the associated logic further includes:

first logic coupled to the integrated display, the first logic for prompting the user one the integrated display to enter an access code for the wireless keyboard if the wireless keyboard is powered on and no access code had previously been entered;

second logic coupled to a wireless front end, the second logic for operating a wireless interface in a disabled mode until a valid access code is typed onto a keypad of the wireless keyboard;

third logic coupled to circuitry for receiving a sequence of key entries, the third logic for comparing the sequence of key entries to a specified access code and for determining if the sequence of key entries match the specified access code, and, responsive to the sequence of key entries matching the specified access code providing an indication of a match, wherein the second logic is operable to enable the wireless interface to operate in a wireless interface enabled mode based upon the match; and

fourth logic for establishing a master/slave relationship with at least one other wireless device according to a specified PAN protocol.

16. The wireless keyboard of claim 15 further including logic for prompting the user through the integrated wireless keyboard display to define a password for a keyboard master.

17. The wireless keyboard of claim 16 further including logic for enabling a wireless interface after a keyboard master password is created, and for displaying at least one wireless device with which a personal area network may be established.

18. The wireless keyboard of claim 16 further including logic for prompting the user to enter a password to gain access to a selected wireless device and transmitting the entered password to the selected wireless device.

19. The wireless keyboard of claim 18 further including logic for prompting the user of the keyboard master password to create a plurality of passwords and corresponding access levels for a plurality of other wireless devices.

20. The wireless keyboard of claim 19 wherein the wireless keyboard is operable to define a plurality of personal area networks for each password and, whenever a user password is entered, to provide a list of access devices for selection for which the wireless keyboard may wirelessly couple.
