US Patent: 5,842,170

Claims:

1. A system for editing messages in a recorder system, comprising:

a handheld recorder having flash memory for storing messages in message segments, the flash memory having a plurality of sequential memory blocks, each memory block having a plurality of memory locations, the messages being stored as message segments, wherein related message segments are logically related to each other using memory address pointers, and wherein a first message segment of each of the messages are linked to each other using the memory address pointers to thereby facilitate movement between the messages;

means for selecting an edit point within a message at which the message is to be edited, the edit point being at a first location within the message defining an end point of a first message segment;

means for generating an edited message, the edited message comprising a second message segment;

means for storing said second message segment in a second memory block;

means for altering said memory address pointers to insert the address of the second message segment;

means for playing said message segments in the flash memory in accordance with said ordered sequence by accessing the message segments corresponding to the addresses contained in the memory address pointers so that the message segments are played sequentially.

2. The system of claim 1, wherein said second message segment comprises a message fragment to be inserted into said message at the edit point, said means for altering the memory address pointers comprises means for connecting the address of the edit point to a beginning of the second memory segment and the end point of the second memory segment to an address after the edit point, and said means for playing comprises means for sequentially playing said first message segment to said edit point, playing said second message segment, and playing said message after the edit point sequentially to form a continuous message.

3. The system of claim 1, wherein said edited message generating means comprises means for playing said message said edit point to a second edit point and means for removing a segment of said message between said edit point and said second edit point, said memory address pointers altering means comprising means for connecting the address of said edit point to the address of said second edit point, and wherein said playing means comprises means for playing said first message segment and a remainder of the message after said second edit point to thereby form a continuous message.

4. The system of claim 3, wherein said edit point is at an address at a beginning of a message in the flash memory and said second edit point is at an address at an end of the message in the flash memory so that the entire message is deleted from the flash memory.

7. A method for editing messages in a recorder system, comprising:

providing a handheld recorder having flash memory for storing messages in message segments, the flash memory having a plurality of sequential memory blocks, each memory block having a plurality of memory locations, the messages being stored as message segments, wherein related message segments are logically related to each other using memory address pointers, and wherein a first message segment of each of the messages are linked to each other using the memory address pointers to thereby facilitate movement between the messages;

selecting an edit point within a message at which the message is to be edited, the edit point being at a first location within the message defining an end point of a first message segment;

generating an edited message, the edited message comprising a second message segment;

storing said second message segment in a second memory block;

altering said memory address pointers to insert the address of the second message segment;

playing said message segments in the flash memory in accordance with said ordered sequence by accessing the message segments corresponding to the addresses contained in the memory address pointers so that the message segments are played sequentially.

8. The method of claim 7, wherein said second memory segment comprises a message segment to be inserted into said message at the edit point; said altering the memory address pointers comprises connecting a beginning address of the edit point to an address of a beginning of said second message segment and an address of an end of the second message segment to an address of the message after the edit point; and wherein playing the edited message comprises sequentially playing said first message segment up to said edit point, playing said second message segment, and playing the remainder of the message after said edit point to form a continuous message.

9. The method of claim 7, wherein editing comprises playing said message from said edit point to a second edit point, and removing said second message segment between said edit point and said second edit point; said altering said memory address pointers comprises connecting said address of said edit point in said message to said address of said second edit point; and wherein playing the message segments comprises playing the first message segment and the message after the second edit point to form a continuous message.

11. The method of claim 9, wherein said first edit point comprises an address at a beginning of a message and said second edit point comprises an address at an end of a message so that the entire message is deleted from the flash memory.

12. The method of claim 11 wherein the first edit point comprises an address at the beginning of a first message in the flash memory and said second edit point comprises an address at the end of a last message in the flash memory so that all of said messages within said flash memory are deleted.
