РЕФЕРАТ (Abstract)

A method and device for determining a concentration of a biological target. The method and device include: capturing an image of a ticket including the biological target and information about the ticket; selecting pre-determined data corresponding to the ticket and the target responsive to the read information about the ticket; and determining the concentration of the biological target according to the pre-determined data. The method and device may further comprise selecting calibration data corresponding to the ticket, responsive to the read information about the ticket; and determining the concentration of the biological target according to the pre-determined data and the calibration data.

ФОРМУЛА ИЗОБРЕТЕНИЯ (CLAIMS)

What is claimed is:

1. A method for determining a concentration of a biological target, the method comprising: capturing an image of a ticket including the biological target and information about the ticket; selecting pre-determined data corresponding to the ticket and the target responsive to the read information about the ticket; and determining the concentration of the biological target according to the pre-determined data.

2. The method of claim 1, further comprising selecting calibration data corresponding to the ticket, responsive to the read information about the ticket; and determining the concentration of the biological target according to the pre-determined data and the calibration data.

3. The method of claim 1, wherein the pre-determined data is a curve including concentration information about the target.

4. The method of claim 3, wherein the curve is described by the following equation:
Y=Bottom+(Top−Bottom)/(1+10^((LogEC50−X)*HillSlope)), where X is the Log of target concentration, Y is the reader response, Y starts at Bottom and goes to Top with a sigmoid shape, LogEC50 is middle of the slope of the curve, and HillSlope is a slope variable for the slope of the curve.

5. The method of claim 4, further comprising indexing Bottom, Top, LogEC50, and HillSlope parameters to each target, and saving the indexed data in a memory.

6. The method of claim 1, wherein the information about the ticket is stored in one or more of a one dimensional barcode and a two dimensional barcode.

7. The method of claim 1, wherein the information about the ticket is stored in a RFID chip.

8. The method of claim 1, wherein the pre-determined data is a look-up table stored in a memory.

9. The method of claim 1, further comprising displaying the concentration of the biological target.

10. The method of claim 1, further comprising: removing noise effects of the captured image of the information about the ticket; obtaining a black and white binary map of the captured image of the information about the ticket; scanning the binary map of the captured image; decoding the scanned binary map of the captured image; and selecting calibration data corresponding to the ticket, responsive to decoded binary map of the captured image.

11. A device for determining a concentration of a biological target comprising: an optical module for capturing an image of a ticket including the biological target and information about the ticket; a sensor for converting the captured image to digital data; and a processor for processing the digital data, selecting pre-determined data corresponding to the ticket and the target responsive to the read information about the ticket, and determining the concentration of the biological target according to the pre-determined data.

12. The device of claim 11, wherein the processor is configured to perform selecting calibration data corresponding to the ticket responsive to the read information about the ticket, and determining the concentration of the biological target according to the pre-determined data and the calibration data.

13. The device of claim 11, wherein the pre-determined data is a curve including concentration information about the target.

14. The device of claim 13, wherein the curve is represented by the following equation:
Y=Bottom+(Top−Bottom)/(1+10^((LogEC50−X)*HillSlope)), where X is the Log of target concentration, Y is the reader response, Y starts at Bottom and goes to Top with a sigmoid shape, LogEC50 is middle of the slope of the curve, and HillSlope is a slope variable for the slope of the curve.

15. The device of claim 14, further comprising means for indexing Bottom, Top, LogEC50, and HillSlope parameters to each target, and a memory for saving the indexed data.

16. The device of claim 11, further comprising one or more of a one dimensional barcode and a two dimensional barcode for storing the information about the ticket.

17. The device of claim 11, further comprising a RFID chip for storing the information about the ticket.

18. The device of claim 11, further comprising a memory, and wherein the pre-determined data is a look-up table stored in the memory.

19. The device of claim 11, further comprising a display for displaying the concentration of the biological target.

20. The device of claim 11, further comprising: an image binarization module for removing noise effects and obtaining a black and white binary map of the captured image of the information about the ticket; a scanning module for scanning the binary map of the captured image; and an information decoding module for decoding the scanned binary map of the captured image and selecting calibration data corresponding to the ticket, responsive to decoded binary map of the captured image.
