Abstract
Abstract A method and apparatus are provided for calibrating a sensor for determination of analyte concentration. The meter 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 can be coupled to the processor for storing predefined parameter data values. A calibration code is associated with the sensor and read by the processor before the user sample to be measured is received. The calibration code is used in measuring the predefined parameter data value to compensate for different sensor characteristics.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
76 words
A system for determination of analyte concentration in a test sample comprising: sensor means for receiving a user sample; processor means responsive to said sensor means for performing a predefined test sequence for measuring a predefined parameter value; and autocalibration code means, operatively associated with the sensor means, coupled to said processor means for providing autocalibration encoded information read by the processor, said autocalibration encoded information being utilized by the processor for said predefined test sequence.
Claim 2
Dependent Claim
32 words
A system as recited in claim 1 wherein said autocalibration code means comprise a plurality of electrical contacts defining a predefined encoded bit pattern defining a sync position and a calibration code.
Claim 3
Dependent Claim
44 words
A system as recited in claim 2 wherein said plurality of electrical contacts defining said autocalibration encoded information include at least two sync contacts defining said sync position, said at least two sync contacts being positioned relative to each other for encoding predefined information.
Claim 4
Dependent Claim
45 words
A system as recited in claim 3 wherein said at least two sync contacts including a predefined one of multiple relative position combinations between sync contacts of no gap, a gap of one space, a gap of two spaces, and a gap of three spaces.
Claim 5
Dependent Claim
28 words
A system as recited in claim 1 wherein said autocalibration encoded information is defined by electrically interconnected sets of contacts on a label carried by said sensor means.
Claim 6
Dependent Claim
50 words
A system as recited in claim 1 further includes an enclosure, said enclosure formed by a base member and a cover member; said cover member and said sensor means include cooperating means for receiving and positioning said sensor means; and said base means supports a predetermined number of autocalibration pins.
Claim 7
Dependent Claim
62 words
A system as recited in claim 6 wherein said base member and said cover member are pivotably attached together at a first end and are secured together by a latch member at a second, opposite end; and said autocalibration code means comprises a label defining said autocalibration encoded information and wherein said label is carried by a package containing multiple sensor means.
Claim 8
Independent Claim
65 words
A method for calibrating a sensor system comprising the steps of: providing the sensor system with a sensor for receiving a user sample and a processor for performing a predefined test sequence for measuring a predefined parameter value; providing calibration encoded information with said sensor, and reading said calibration encoded information by said processor and utilizing said calibration encoded information for said predefined test sequence.
Claim 9
Dependent Claim
38 words
A method for calibrating a sensor system as recited in claim 8 wherein said step of providing calibration encoded information with said sensor includes the step of defining a calibration encoded label on a package containing said sensor.
