20080268485 | Iconic Display of Markers for a Meter - This invention relates to an iconic display of pre-event or post-event iconic markers for a meter and a method for marking an analyte concentration with a pre-event or post-event iconic marker. The meter includes at least one segment on a display adapted to show a pre-event or post-event iconic marker. The user can interact with the meter via a button on the meter. The button allows the user to scroll from pre-event, post-event, and neither iconic marker, and it also allows the user to select one or neither of the iconic markers. A memory device located within the meter stores the analyte concentration with the corresponding pre-event, post-event, or neither iconic marker. | 10-30-2008 |
20090068754 | Transient Decay Amperometry - A biosensor system determines an analyte concentration of a biological sample using an electrochemical process without Cottrell decay. The biosensor system generates an output signal having a transient decay, where the output signal is not inversely proportional to the square root of the time. The transient decay is greater or less than the −0.5 decay constant of a Cottrell decay. The transient decay may result from a relatively short incubation period, relatively small sample reservoir volumes, relatively small distances between electrode surfaces and the lid of the sensor strip, and/or relatively short excitations in relation to the average initial thickness of the reagent layer. The biosensor system determines the analyte concentration from the output signal having a transient decay. | 03-12-2009 |
20090081082 | Auto-calibration label and methods of forming the same - An auto-calibration circuit or label is adapted to be used with different instruments.

20090127135 | Method and System for Checking an Electromechanical Biosensor - A method of operating a meter for determining the concentration of an analyte in a current sample and for self-detecting electrical connection errors like short or open circuit between the electrodes of a biosensor. The method includes providing a connector with a plurality of contacts and coupling each of the plurality of contacts to one of a plurality of electrical leads on a biosensor, such that each of the plurality of connector contacts electrically contacts a corresponding one of the plurality of electrical leads. The meter obtains a first measurement between a pair of the plurality of connector contacts prior to the fluid sample being applied. The meter also obtains a second measurement between the pair of the plurality of connector contacts after the fluid sample is applied. In response to either the first or the second measurements being outside a predetermined range, a fault is indicated. | 05-21-2009 |
