Abstract

Methods, systems, and computer program products for compressing a data file that includes a plurality of frames, wherein each frame includes a plurality of data words. An example computer based system retrieves data from corresponding data word locations in the plurality of frames in the original data file, stores the retrieved data words sequentially in a second data file, and compresses the second data file. The system creates the original data file by retrieving data from a plurality of sources and storing the retrieved data into corresponding data word locations within frames of the original data file. The second data file is stored on a removable storage device, such as a PCMCIA card, or is transmitted to a remote computer system.

Claims

1. A method of compressing a first data file including a plurality of frames, wherein each frame includes a plurality of data words, the method comprising:

retrieving data from corresponding data word locations in the plurality of frames in the first data file;

storing the retrieved data words sequentially in a second data file; and

compressing the second data file.

2. The method of claim 1, further comprising:

determining the number of complete frames of data in the first data file,

wherein storing is further based on the determined number of complete frames of data.

3. The method of claim 1, wherein the first data file includes data retrieved from a plurality of sources and stored into corresponding data word locations within frames of the first data file.

4. The method of claim 1, further comprising:

storing the second data file on a removable storage device.

5. The method of claim 1, further comprising:

wirelessly transmitting the second data file to a computer system.

6. The method of claim 1, further comprising:

performing retrieving, storing, compressing, and determining on a computer system within a vehicle.

7. The method of claim 6, wherein the vehicle is an aircraft and the first data file is a flight data file.

8. The method of claim 7, further comprising:

determining if a trigger event has occurred, wherein the trigger event includes at least one of end of operation of the aircraft or end of data retrieval,

wherein retrieving data if it was determined that a trigger event has occurred.

9. The method of claim 1, further comprising:

uncompressing the compressed data file; and

reordering the uncompressed data file into the same format as the first data file.

10. A computer program product for compressing a first data file including a plurality of frames, wherein each frame includes a plurality of data words, the product comprising:

a first component for retrieving data from corresponding data word locations in the plurality of frames in the first data file;

a second component for storing the retrieved data words sequentially in a second data file; and

a third component for compressing the second data file.

11. The product of claim 10, further comprising:

a fourth component for determining the number of complete frames of data in the first data file,

wherein the second component is based on the determined number of complete frames of data.

12. The product of claim 10, wherein the first data file includes data retrieved from a plurality of sources and stored into corresponding data word locations within frames of the first data file.

13. The product of claim 10, further comprising:

a fourth component for storing the second data file on a removable storage device.

14. The product of claim 10, further comprising:

a fourth component for wirelessly transmitting the second data file to a computer system.

15. A computer-based system for compressing a predetermined first data file, the first data file includes a plurality of frames, wherein each frame includes a plurality of data words, the system comprising:

a processor comprising;

a first component for retrieving data from corresponding data word locations in the plurality of frames in the first data file;

a second component for storing the retrieved data words sequentially in a second data file; and

a third component for compressing the second data file.

16. The system of claim 15, wherein the processor further comprises:

a fourth component for determining the number of complete frames of data in the first data file,

wherein the second component stores further based on the determined number of complete frames of data.

17. The system of claim 15, wherein the processor further comprises:

a fourth component for creating the first data file by retrieving data from a plurality of sources and storing the retrieved data into corresponding data word locations within frames of the first data file.

18. The system of claim 15, further comprising:

a removable storage device coupled to the processor,

wherein the processor further comprises a fourth component for storing the second data file on the removable storage device.

19. The system of claim 18, wherein the removable storage device is a PCMCIA card.

20. The system of claim 15, further comprising:

a wireless data transmission system coupled to the processor,

wherein the processor further comprises a fourth component for wirelessly transmitting the second data file to a computer system via the wireless data transmission system.

21. The system of claim 15, wherein the system is implemented on an aircraft.

22. The system of claim 21, wherein the first data file is a flight data file.

23. A system on an aircraft, the system comprising:

a databus coupled to one or more flight data systems, the databus configured to communicate a plurality of flight data;

a processor comprising;

a first component for retrieving at least a portion of the plurality of flight data from the databus;

a second component for creating a first data file by inserting the retrieved flight data into corresponding data word locations in frames based on time;

a third component for retrieving data from corresponding data word locations in the plurality of frames of the first data file;

a fourth component for storing the retrieved data words sequentially in a second data file; and

a fifth component for compressing the second data file; and

a removable storage device coupled to the processor for storing the compressed second data file.

24. The system of claim 23, wherein the removable storage device is a PCMCIA card.

25. A system on an aircraft, the system comprising:

a databus coupled to one or more flight data systems, the databus configured to store a plurality of flight data previously generated by one or more aircraft systems;

a processor comprising;

a first component for retrieving a portion of the plurality of flight data from the databus;

a second component for creating a first data file by inserting the retrieved flight data into corresponding data word locations in frames based on time;

a third component for retrieving data from corresponding data word locations in the plurality of frames in the first data file;

a fourth component for storing the retrieved data words sequentially in a second data file; and

a fifth component for compressing the second data file; and

a data transmitter coupled to the processor for transmitting the second data file to a computer system remote from the aircraft.
