Abstract

A method and apparatus are provided for marking predetermined events with a biosensor. The biosensor includes a sensor for receiving a user sample to be measured and a processor for performing a predefined test sequence for measuring a predefined parameter value. A memory is coupled to said processor for storing predefined parameter data values. A marker member is manually coupled by the user to the processor for selectively marking one of a plurality of predetermined events with a stored predefined parameter data value.

Claims

1. A biosensor comprising:

means for receiving a user sample;

processor means responsive to said user sample receiving means for performing a test sequence for measuring a set parameter value;

memory means coupled to said processor means for storing said set parameter data values;

a marker member, said marker member being manually coupled by the user to said processor means for selectively marking one of a plurality of set events with a stored set parameter data value, said marker member including a plurality of different electrically measurable values corresponding to said plurality of set events.

2. A biosensor as recited in claim 1 wherein said marker member includes a plurality of different resistance values, one of said different resistance values being manually coupled by the user to said processor means for selectively marking one of a plurality of set events.

3. A biosensor as recited in claim 2 wherein said marker member includes a plurality of spokes and wherein each of said plurality of spokes applies a signal to said processor means corresponding to one of said set events.

4. A biosensor as recited in claim 3 wherein said each of said plurality of spokes contains a different resistance value.

5. A biosensor as recited in claim 1 further includes a housing and said housing including an aperture for slideably receiving said marker member that is manually inserted by the user into said aperture.

6. A biosensor as recited in claim 5 wherein said housing carries a slide member coupled to said processor means and manually movable by the user for selecting ON/OFF operational modes.

7. A biosensor as recited in claim 5 wherein said housing carries a switch coupled to said processor means and manually operated by the user for selecting operational characteristics for the biosensor.

8. A biosensor as recited in claim 1 wherein said processor means includes means for detecting an error condition and means responsive to a detected error condition for displaying a set corresponding error code.

9. A biosensor as recited in claim 1 wherein said processor means includes means for performing set system features operational modes responsive to a user selection.

10. A method for marking set events with a biosensor comprising the steps of:

providing the biosensor with a sensor for receiving a user sample and a processor for performing a test sequence for measuring a predefined parameter value;

providing a marker member including a plurality of different electrically measurable values; and

selectively manually coupling one of said plurality of different electrically measurable values by the user to said processor for selectively marking one of a plurality of set events.
