Abstract

Disclosed are various preferred embodiments for dynamic transfer of information from a test sensor to an analyte medical test device. Exemplary embodiments include various containers, systems and methods.

Claims

1. A method of transmitting data, the method comprising:

providing discrete surface features on a surface of a container indicative of predetermined parameters for at least one test strip disposed in the housing;

inserting the container into a test port of the test device;

removing the container out of the test port; and

reading the discrete surface features as the container is moving relative to the test port during one of the removing and inserting steps to provide parameters specific to the test strip.

2. The method of claim 1, wherein the reading comprises recognizing the surface features during the inserting.

3. The method of claim 2, wherein the reading comprises recognizing the surface features during the removing.

4. The method of claim 1, wherein the reading comprises decoding data encoded by the surface features during the inserting and removing:

comparing data during the removing with data during the inserting; and

outputting a signal indicative of any difference in the data during the removing and data during the inserting.

5. The method of claim 1, further comprising retaining the test strip to the sampling port subsequent to separation of the container from the test device.

6. The method of claim 1, wherein the surface features comprise;

a first plurality of discrete surface features disposed on the outer surface to define a first data line; and

a second plurality of discrete surface features disposed on the outer surface in a repeating sequence to define a clock line.

7. The method of claim 1, wherein the reading comprises recognizing transitions between the second plurality of discrete surface features to coordinate reading of the first data line.

8. The method of claim 7, wherein the reading comprises

correlating the transitions of the clock line to transitions between the first plurality of discrete surface features;

and

providing binary data from the correlating.

9. The method of claim 7, wherein the reading further comprises recognizing from the second plurality of discrete surfaces a predetermined geographic region for the at least one test strip.

10. The method of claim 7, wherein the first plurality of discrete surface features includes a first plurality of low and high reflectance areas disposed on the outer surface to define a first data line;

and the second plurality of discrete surface features includes a second plurality of low and high reflectance areas disposed on the outer surface in a repeating sequence along a second perimeter to define timing intervals for the first data line.

11. The method of claim 10, wherein the data lines further comprise information selected from a group consisting essentially of calibration parameters, calibration code, geographical data, error checking data, lot number, manufacturing date, expiration date, batch number, manufacturer'"'"'s name, chemical composition, ingredients, and combinations thereof

12. The method of claim 8, wherein each of the first and second plurality of discrete features comprises a plurality of raised and depressed surfaces formed on the outer surface.

13. The method of claim 8, wherein discrete surface features comprise:

a first plurality of low and high reflectance areas disposed on the outer surface to define a first data line; and

a second plurality of low and high reflectance areas disposed on the outer surface in a repeating sequence along a second perimeter to define timing intervals for the first data line.

14. A method to transmit data containing at least one or more predetermined parameters to a medical test device, the method comprising:

providing discrete surface features on a surface of a container indicative of predetermined parameters for at least one test strip disposed in the housing;

inserting the container into a port of the test device;

retaining the at least one test strip in the port of the test device;

removing the container out of the test port;

confirming that the at least one test strip is retained in the port; and

reading the discrete surface features during one of the removing and inserting and only upon confirmation by the confirming step.

15. The method of claim 14, wherein the reading comprises recognizing the surface features during the inserting.

16. The method of claim 14, wherein the reading comprises recognizing the surface features during the removing.

17. The method of claim 14, wherein the reading comprises decoding data encoded by the surface features during the inserting and removing;

comparing data during the removing with data during the inserting; and

outputting a signal indicative of any difference in the data during the removing and data during the inserting.

18. The method of claim 14, wherein the surface features comprise:

a first plurality of discrete surface features disposed on the outer surface to define a first data line; and

a second plurality of discrete surface features disposed on the outer surface in a repeating sequence to define a clock line.

removing the container out of the test port;

confirming that the at least one test strip is retained in the port;

reading the discrete surface features during one of the removing and inserting only upon confirmation that the at least one test strip is retained; and

verifying the reading with a human observable output by the test device.

21. The method of claim 20, wherein the surface features comprise:

a first plurality of discrete surface features disposed between the inner and outer surfaces to define a first data line; and

a second plurality of discrete surface features disposed between the inner and outer surfaces in a repeating sequence to define a clock line.

22. The method of claim 21, wherein the reading comprises:

recognizing transitions between the second plurality of discrete surface features of the clock line;

correlating the transitions of the clock line to transitions between the first plurality of discrete surface features into binary data; and

validating the binary data with prestored binary data in the test device.
