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. An apparatus for facilitating the synchronization of data between a first personal digital assistant (PDA) device and a second PDA device, said apparatus comprising:

a selector;

a memory having a data transfer program for translating information from a format usable by an operating system of said first PDA to a format usable by an operating system of said second PDA and vice versa, wherein said memory further includes a FIFO memory queue in a linked list configuration, wherein said FIFO memory queue includes a plurality of linked lists, wherein each of said plurality of linked lists stores a designated catergory of information

a multiplexor for delivering incoming information into a specified one of said plurality of linked lists;

means for wirelessly receiving data from said first PDA to said memory in response to said selector being switched to a first position, wherein said first PDA is placed in close proximity to said apparatus; and

means for wirelessly transmitting data from said memory to second PDA in response to said selector being switched a second position, wherein said second PDA is placed in close proximity to said apparatus.

2. The apparatus of claim 1, wherein said apparatus further includes a processor configured to access information contained in said memory.

3. The apparatus of claim 2, wherein said apparatus further includes a user-operated input interface for delivering commands to said processor.

4. The apparatus of claim 3, wherein said user-operated input interface includes a mouse, a stylus, a rollerball, or a button.

5. The apparatus of claim 2, wherein said memory stores a plurality of operating systems usable by said processor.

6. The apparatus of claim 1, wherein said apparatus further includes a display for displaying contents of said FIFO memory queue.

7. The apparatus of claim 6, wherein said apparatus further includes a data pointer for providing said contents of said FIFO memory queue to said display.

8. The apparatus of claim 1, wherein said apparatus further includes a demultiplexor for retrieving data objects from among said plurality of linked list according to a specific data retrieval request.
