Abstract: In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface.

Abstract: An analyte test sensor for use in measuring the concentration of a particular analyte in a test sample includes a non-conductive substrate, a reference electrode deposited on the substrate, a working electrode deposited on the substrate and a compensation electrode deposited on the substrate. The compensation electrode is provided with a resistive ladder and is designed to correct for test result inaccuracies which are the result of variances in the manufacturing of the test sensor. Specifically, in one embodiment, the compensation electrode corrects for test result inaccuracies in an analog manner by shunting a portion of the working current away from working electrode. In another embodiment, the compensation electrode corrects for test result inaccuracies in a digital manner by providing a calibration code which is proportional its resistance value. A batch of analyte test sensors are preferably manufactured in the following manner. An initial batch of the test sensors is constructed. Then, a limited sampling of the sensors is tested for accuracy using a control sample. Based on the test results, the resistance value of the compensation electrode for each remaining sensor in the batch is adjusted accordingly.

Abstract: The present invention describes a replaceable breath alcohol sensor module that can be replaced with a new pre-calibrated breath alcohol sensor module or re-calibrated. The breath alcohol sensor module requiring calibration can be removed from the body of a Breath Alcohol Testing Device (commonly called “breathalyser” or “breathalyzer”). The breath alcohol sensor module can be separately calibrated for accurate calculation of “percent blood alcohol concentration” (% BAC) based on breath air samples and then re-installed into the breath alcohol tester or the old breath alcohol sensor module can be replaced with a new pre-calibrated breath alcohol sensor module. The present invention improves upon and/or replacing the current method of re-calibration at a breathalyzer service center.
