Abstract

A wireless data retrieval device and method for implementing the same. In accordance with one embodiment of the invention, the wireless data retrieval device includes a first-in-first-out (FIFO) memory queue in the form of a linked list that stores standardized correspondence information. The wireless data retrieval device further includes an input/output device configured to transmit the standardized correspondence information to and receive said standardized correspondence information from a wireless channel.

Claims

1. A wireless data retrieval device comprising:

a first-in-first-out (FIFO) memory queue for storing standardized correspondence information; and

an input/output device configured to transmit said standardized correspondence information to and receive said standardized correspondence information from a wireless channel.

2. The wireless data retrieval device of claim 1, wherein said FIFO memory queue is a linked list.

3. The wireless data retrieval device of claim 1, further comprising:

a system memory that stores a data transfer program configured to translate said standardized correspondence information into a format usable by an operating system of a personal digital assistant (PDA) operating system; and

a processor configured to access information contained in said system memory and said FIFO memory queue.

4. The wireless data retrieval device of claim 3, further comprising a user-operated input interface for delivering commands to said processor.

5. The wireless data retrieval device of claim 4, wherein said user-operated input interface comprises a mouse, a stylus, a rollerball, or a button.

6. The wireless data retrieval device of claim 3, wherein said system memory stores a plurality of operating systems usable by said processor.

7. The wireless data retrieval device of claim 1, further comprising a display device that displays contents of said FIFO memory queue.

8. The wireless data retrieval device of claim 7, further comprising a data pointer that provides said contents of said FIFO memory queue to said display device.

9. The wireless data retrieval device of claim 1, wherein said FIFO memory queue comprises a plurality of linked lists, wherein each of said plurality of linked lists stores a designated category of correspondence information.

10. The wireless data retrieval device of claim 9, further comprising a multiplexor for delivering incoming correspondence information into a specified one of said plurality of linked lists.

11. The wireless data retrieval device of claim 9, further comprising a demultiplexor for retrieving data objects from among said plurality of linked lists, wherein said data objects correspond to a given data retrieval request.

13. The method of claim 12, wherein said step of storing standardized correspondence information into a FIFO memory queue further comprises adding said standardized correspondence information as a sequence of data objects in a linked list.

14. The method of claim 12, further comprising:

translating said standardized correspondence information into a format usable by an operating system of a personal digital assistant (PDA) operating system; and

utilizing a user-operated input interface to access information contained in said FIFO memory queue.

15. The method of claim 12, further comprising displaying contents of said FIFO memory queue on a user-readable display device.

16. The method of claim 15, further comprising a data pointer that provides said contents of said FIFO memory queue to said user-readable display device.

17. The method of claim 12, wherein said FIFO memory queue comprises a plurality of linked lists, said method further comprising storing a designated category of correspondence information within each of said plurality of linked lists.

18. The method of claim 17, further comprising multiplexing incoming correspondence information into a specified one of said plurality of linked lists.

19. The method of claim 17, further comprising demultiplexing data objects from among said plurality of linked lists, wherein said data objects correspond to a given data retrieval request.

12. A method for dispensing correspondence data to and from a digital system over a wireless medium, said method comprising:

storing standardized correspondence information into a first-in-first-out (FIFO) memory queue; and

transmitting said standardized correspondence information to and receiving said standardized correspondence information from a wireless channel.
