Abstract

A computer system for decoding a signal of decodable indicia is disclosed. The computer system includes a laser scanner configured that outputs a signal of decodable indicia and a microprocessor that include a camera sensor interface that is configured to receive the signal from the laser scanner.

First claim

The invention claimed is:

1. A system for decoding a signal, the system comprising:
an optical scanner configured to output a signal;
a memory configured to receive the signal from the optical scanner; and
a processor configured to read the signal from the memory at pre-determined time intervals and to pack the signal into at least one image frame.

2. The system of claim 1 , comprising a microprocessor comprising a camera sensor interface configured to receive the signal from the optical scanner.

3. The system of claim 1 , wherein the at least one image frame comprises header information.

4. The system of claim 3 , wherein the at least one image frame is of a fixed size and wherein the at least one image frame is comprised of envelopes, and wherein the header information comprises references to data pointers within the envelopes.

5. The system of claim 1 , comprising a configuration register coupled to the memory wherein the configuration register sets parameters for the at least one image frame.

6. The system of claim 5 , wherein the parameters comprise one or more of: image size, image format, and image rate.

7. The system of claim 1 , the processor is configured to produce digital signals while packing the signal into the at least one image frame, wherein the digital signals comprise a data line, a pixel clock, a horizontal sync enable line, and a vertical sync enable line.

8. The system of claim 1 , wherein the signal corresponds to at least one of: a 1D bar code, a 2D bar code, and one or more OCR symbols.

9. The system of claim 1 , wherein the memory is a FIFO memory buffer.

10. A method, comprising:
receiving, with a computer, a signal from an optical reading device configured to output the signal;
responsive to receiving the signal, storing the signal, with the computer, in a memory buffer;
reading the signal, with the computer, from the memory buffer at pre-determined time intervals;
packing the signal, with the computer, into an image frame;
receiving, with the computer, the image frame;
responsive to receiving the image frame, attempting to locate, with the computer, a decodable indicia in the image frame; and
decoding, with the computer, the decodable indicia.

11. The method of claim 10 , comprising setting, with the computer, parameters for the image frame.

12. The method of claim 11 , wherein the parameters comprise one or more of: image size, image format, and image rate.

13. The method of claim 10 , comprising producing digital signals, with the computer, while packing the signal into the image frame, wherein the digital signals comprise a data line, a pixel clock, a horizontal sync enable line, and a vertical sync enable line.

14. The method of claim 10 , wherein the signal is a laser signal.

15. The method of claim 10 , wherein the decodable indicia is provided by at least one of: a 1D bar code, a 2D bar code, and one or more OCR symbols.

16. A computer program product, comprising:
one or more computer-readable tangible storage devices;
program instructions, stored on at least one of the one or more storage devices, to receive a signal from a client, wherein the client is provided by an optical reading device configured to output the signal;
program instructions, stored on at least one of the one or more storage devices to, responsive to receiving the signal, store the signal in at least one of the computer-readable tangible storage devices at pre-determined time intervals;
program instructions, stored on at least one of the one or more storage devices, to read the signal from the at least one of the computer-readable tangible storage devices;
program instructions, stored on at least one of the one or more storage devices to pack the signal into at least one image frame;
program instructions, stored on at least one of the one or more storage devices to receive the at least one image frame;
program instructions, stored on at least one of the one or more storage devices to, responsive to receiving the at least one image frame, attempt to locate a decodable indicia in the at least one image frame; and
program instructions, stored on at least one of the one or more storage devices to decode the decodable indicia.

17. The computer program product of claim 16 , wherein the at least one image frame comprises header information.

18. The computer program product of claim 16 , comprising at least one configuration register coupled to the at least one of the computer-readable tangible storage devices wherein the least one configuration register sets parameters for the at least one image frame.

19. The computer program product of claim 18 , wherein the parameters comprise one or more of: image size, image format, and image rate.

20. The computer program product of claim 16 , comprising program instructions, stored on at least one of the one or more storage devices, to produce digital signals while packing the signal into the at least one image frame, wherein the digital signals comprise a data line, a pixel clock, a horizontal sync enable line, and a vertical sync enable line.
