Abstract: 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.

Abstract: When performing failure prediction on an optical transceiver, the output optical power and an operational current of a transmission optical sub-assembly in the optical transceiver are recorded during the operation of the optical transceiver. A first ratio is acquired by dividing the average slope of the operational current recorded at a current time period by the average slope of the operational current recorded at an earlier time period. A second ratio is acquired by dividing the absolute average value of the slope of the output optical power recorded at the earlier time period by the absolute average value of the slope of the output optical power recorded at the current time period. When it is determined that the product of the first ratio and the second ratio is greater than a threshold value, a failure notification including life prediction information is provided.
