Abstract

A system and method for use in accessing and displaying information is disclosed. The system and method may include a hand-held device for displaying information; the device may include a processor; a memory; and a word dictionary table stored in the memory. The word dictionary table may include a word list of unique words within the information. The word dictionary table may also include a set of word identification tokens that each represent a word in the list. The memory may also include a phrase dictionary table, which may include a phrase list of word identification token groups, each word identification token group representing a phrase that is contained in the information. The phrase dictionary table may further include a set of phrase identification tokens, each representing one of the phrases in the textual information. The memory may be updated or synchronized via a network that includes a satellite link.

Claims

1. A method for maintaining data comprising:

storing a word dictionary in a memory, the word dictionary including a first list of the unique words that are contained in the data and that also includes a set of word identification tokens, each word identification token representing one of the unique words in the first list;

storing a phrase dictionary in the memory, the phrase dictionary including a second list of word identification token groups, each word identification token group representing a phrase that is contained in the data, the second list further including a set of phrase identification tokens, each phrase identification token representing one of the word identification token groups; and

updating the data via a synchronization interface.

2. The method of claim 1, further comprising the step of:

determining an optimum range of the length of the phrases that are to be included in the phrase dictionary and including only phrases of optimum length in the phrase dictionary.

3. The method of claim 1, wherein the data comprises textual information.

4. The method of claim 3, wherein the textual information comprises automotive repair and servicing information.

5. The method of claim 1, wherein the memory comprises at least one removable module.

6. The method of claim 1, wherein updating the data includes receiving, at the synchronization interface, data from a communications network.

7. The method of claim 6, wherein the synchronization interface comprises a wireless interface.

8. The method of claim 6, wherein the synchronization interface comprises a set of electrical contacts communicatively connectable to a synchronization cradle communicatively coupled to a network device.

9. The method of claim 7, wherein the wireless interface is an infrared interface.

10. The method of claim 7, wherein the wireless interface is a radio frequency interface.

11. The method of claim 6, wherein the communications network comprises a satellite network.

12. The method of claim 6, wherein the communications network comprises the Internet.
