Abstract

Abstract A personal communication apparatus includes a digital processor, a memory coupled to the processor, an operating system, stored in the memory and executable by the processor, a touch-screen user interface coupled to the processor and the memory and responsive to file execution commands from the user, and a navigation utility file, executable by the processor, for initiating execution of files and for monitoring the sequence in which file executions occur. The Navigation utility maintains a stack in the memory into which the calling sequences of files are stored according to the order in which files were executed. In one embodiment, the apparatus further comprises a modem and RF transceiver coupled to the processor for receiving and transmitting data. In another embodiment, the communicator further includes a port for receiving an external memory medium containing a plurality of executable files.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 267 words
A hand-held personal communication apparatus comprising: a radio frequency transceiver; audio logic circuitry coupled to said radio frequency transceiver to permit audio data to be received and transmitted by a user; a digital processor; a modem coupled to said digital processor and said radio frequency transceiver to permit digital data to be received and transmitted by a user; a memory coupled to said digital processor for storing a plurality of communication application programs, each of said plurality of communication application programs initiating execution in response to a selected calling sequence and including executable program code for generating at least one graphic image, said at least one graphic image including at least one designated user input area; a display coupled to said digital processor for displaying a graphic image; a touch sensitive overlay coupled to said digital processor and overlaying said display for generating file execution commands in response to user touch commands within a designated user input area; a navigation file stored in said memory, said navigation file including a plurality of ordered entries, each of said ordered entries comprising a calling sequence for one of said plurality of communication application programs; and a navigation program stored within said memory and executable by said digital processor in tandem with each of said plurality of communication application programs for accessing said navigation file and initiating a selected calling sequence in response to a user touch command within a designated user input area wherein a user may efficiently move from one communication application program to another communication application program with minimal user inputs while utilizing said personal communication apparatus.
Claim 2
Dependent Claim 267 words
A hand-held personal communication apparatus comprising: a radio frequency transceiver; audio logic circuitry coupled to said radio frequency transceiver to permit audio data to be received and transmitted by a user; a digital processor; a modem coupled to said digital processor and said radio frequency transceiver to permit digital data to be received and transmitted by a user; a memory coupled to said digital processor for storing a plurality of communication application programs, each of said plurality of communication application programs initiating execution in response to a selected calling sequence and including executable program code for generating at least one graphic image, said at least one graphic image including at least one designated user input area; a display coupled to said digital processor for displaying a graphic image; a touch sensitive overlay coupled to said digital processor and overlaying said display for generating file execution commands in response to user touch commands within a designated user input area; a navigation file stored in said memory, said navigation file including a plurality of ordered entries, each of said ordered entries comprising a calling sequence for one of said plurality of communication application programs; and a navigation program stored within said memory and executable by said digital processor in tandem with each of said plurality of communication application programs for accessing said navigation file and initiating a selected calling sequence in response to a user touch command within a designated user input area wherein a user may efficiently move from one communication application program to another communication application program with minimal user inputs while utilizing said personal communication apparatus.
Claim 3
Dependent Claim 28 words
A hand-held personal communication apparatus according to claim 1, further including a port for receiving an external memory medium having stored thereon a second plurality of application programs.
Claim 4
Dependent Claim 40 words
A hand-held personal communication apparatus according to claim 1, wherein at least one of said ordered entries within said navigation file inlcudes at least one parameter to be passed to a communication application program in association with said calling sequence.
Claim 5
Dependent Claim 25 words
A hand-held personal communiation apparatus according to claim 1, further including a battery power supply coupled to said radio frequency transceiver and said digital processor.
