Analyte test strip and analyte meter device
First Claim
1. A set of test strips comprising a plurality of test strips, each test strip comprising:
- (a) a top substrate;
(b) a bottom substrate;
(c) an electrical connector for connection to a meter disposed at a first end, wherein said electrical connector comprises a first tab formed at the first end of the top substrate, and a second tab formed at the first end of the bottom substrate, and wherein the first tab is not aligned with the second tab;
(d) an electrochemical test cell disposed toward a second end; and
(e) characteristic information encoded on the strip;
wherein;
the plurality of test strips are arranged in a plurality of subgroups comprising a first subgroup and a second subgroup; and
a test strip arranged in the first subgroup is distinguishable from a test strip arranged in the second subgroup by a difference in dimension of the first tabs, the second tabs, or both the first tabs and the second tabs of the respective strips; and
the characteristic information is encoded on the test strip by the dimensions of the first tab, the second tab, or both the first tab and the second tab.

Abstract
A test strip with an incorporated optical waveguide and deflectors punched through the optical waveguide allows light to exit through a layer of the test strip and be detected by a photo detector. Using light and a photodetector, these uniquely coded strips are identified. The waveguide can be constructed by sandwiching two layers of the test strip around a light transmissible layer. This configuration allows light to be transmitted through the test strip and out the other end, as well as allowing some light to escape the deflector. This light is detected by a photodetector mounted in the analyte test meter. The deflectors may be placed in patterns such that detection of this light indicates certain characteristics of the strip, such as non-counterfeit, regional identification, type of analyte tested, and coding information.

in the middle of the tab, on the edge closest to the first tab, and on the edge farthest from the first tab.
