Abstract: Embodiments provide a method and related systems that take into account the difference between a measured glucose value and the calibration level and the amount of elapsed time since the prior calibration. As one or both of these determined differences increases, the desirability of an additional calibration also increases.

If the combination exceeds a predetermined value, the system recommends, but does not require, that the subject user perform an additional calibration.

Abstract: The disclosure relates to a system and method for identifying whether a difference between measured lambda and computed lambda, based on mass air flow and mass fuel flow, is due to a drift in fuel metering or a drift in air metering.

Abstract: During the measurement of the oxygen storage capacity of an oxygen storage system, which is assigned to a catalytic converter, a switchover operation from lean to rich exhaust gas or vice versa is effected. The measurement signals of a lambda probe are recorded; and an integral calculation is carried out over a time interval on the basis of the measurement values. Whereas in the past the start of the time interval was the point in time of the switchover operation, the present invention provides that the start of the second time interval is determined on the basis of the measurement signals of the second lambda probe i.e., the point in time is preferably fixed at the time at which these measurement values reach an extreme value. This design allows the oxygen storage capacity to be measured even if the lambda probe is not fully functioning totally correctly.

Abstract: A process is described for measuring a property of oil extracted from a sample, for example, the viscosity or density. The oil is extracted from the sample using a volatile polar first solvent. A portion of the extracted oil is used to determine a concentration factor. A dry weight of the oil in the sample is calculated using the concentration factor. A second solvent less volatile than the first solvent is added to the remaining extract. The first solvent is substantially removed from the remaining extract. Different amounts of the second solvent are removed from each of a series of sub-samples taken from the remaining extract. Solvent concentrations and viscosity values and/or density values of the solvent-oil mixtures are measured for each sub-sample. Based on the measured solvent concentrations and viscosity values and/or density values, the second-solvent free viscosity and/or density of the oil in the sample is estimated.

Abstract: Container inspection utilizing a linear actuator. A linear actuator shaft is movable such that the shaft end temporarily contacts the container. A feedback parameter resulting from or related to a change of an electrical property of the linear actuator, is detected or determined by a controller, which determines whether the container satisfies pre-determined inspection criteria, e.g., whether the container is properly sealed, satisfies pressure criteria and/or has unacceptable vacuum. These determinations are made based at least in part upon one or more detected feedback parameters including or related to at least one of a change of position of the shaft, a change of velocity of the shaft and a force or torque exerted by the container to the shaft. In this manner, high speed leak detection is performed without a load cell or force transducer, without squeezing or compressing bottles and without determining fill level changes.

Abstract: Four cases are to be distinguished from one another for an exhaust gas line of a motor vehicle with an oxygen storage reservoir and a lambda probe located downstream from at least part of the oxygen storage reservoir, specifically in each case, whether or not the oxygen storage reservoir has sufficient storage capacity and whether or not the lambda probe is fully serviceable. For this purpose, the exhaust gas line is supplied in an alternating sequence with rich and lean exhaust gas, in two different passes the degree of oxygen filling being varied differently. For a minor variation of the degree of oxygen filling, the serviceability of the lambda probe can be deduced on the basis of certain criteria. If the lambda probe is fully serviceable, the sufficiency or insufficiency of the oxygen storage capacity of the oxygen storage reservoir can be deduced for a greater variation of the degree of oxygen filling.

Abstract: The invention describes a method for determining the light-off temperature of a catalytic converter on board a vehicle. The aging condition of the catalytic converter is determined by means of the method. To test the catalytic converter, the latter is loaded for example with a CO/HC test pulse. During the combustion of the additional CO and HC on the catalytic converter, an axial temperature profile is generated. The position of the maximum of said temperature profile along the catalytic converter is dependent on the current light-off temperature. The temperature profile travels through the catalytic converter and can be measured at the outlet of the catalytic converter as a time-dependent profile. The original axial temperature profile can be inferred from the time-dependent profile. Using a calculation program, the current light-off temperature of the catalytic converter on the vehicle can be determined.
