Method of determining information of a test sensor
First Claim
1. A method of determining information of a test sensor, the method comprising the acts of:
- providing an optical read head, the optical read head including a light source, a light guide and a detector, the optical read head forming an opening that is sized to receive a test sensor, the optical read head having a thickness of less than about 0.2 inch;
placing the test sensor in the opening of the optical read head;
transmitting light from the light source to the test sensor;
detecting the light transmitted through the test sensor or detecting the absence of light being transmitted through the test sensor using the detector; and
using the detected light or the absence of detected light information from the detector to determine the information of the test sensor,wherein the information is market information, country information, expiration dates, analyte type information, or counterfeit test sensor information.

Abstract
A method of determining auto-calibrating information of a test sensor includes providing an optical read head that includes a light source, a light guide and a detector. The read head forms an opening that is sized to receive a test sensor. The detector includes a linear-detector array or single detector. A test sensor is provided having apertures formed therein. The test sensor is placed in the opening of the optical read head. Light is transmitted from the light source through the apertures. The light transmitted through the apertures using the detector or detecting the absence of light being transmitted through the test sensor using the detector is detected. The detected light or the absence of detected light information from the detector is used to determine the auto-calibration information of the test sensor.
