    摘要： A process for cleaning exhaust gas flow from an internal combustion engine using a catalyst, a lambda probe is disposed in the exhaust gas flow upstream from the catalyst and is connected to a controller that actuates the lambda probe, the controller receives a raw signal output from the lambda probe and forms a measurement signal that is supplied to control the internal combustion engine. The process includes regulating operation of the internal combustion engine such that a predetermined value of the lambda probe corresponds to a certain level of the measurement signal. Trimming the certain level of the measurement signal by a set value determined with an additional measuring pickup located downstream of the catalyst is performed, the trimming corrects the certain level of the measurement signal that corresponds to the predetermined value of the lambda probe. Switching the controller to a test mode in predetermined states of operation by the internal combustion engine and determining an actual value of a measurement signal falsification developed in the controller is performed. Compensating the measurement signal inversely to the actual value of the measurement signal falsification takes place. Varying the set value inversely to the actual value of the measurement signal falsification is performed.

    摘要： In one embodiment, a method is provided for congestion mitigation. In this method, a congestion level of data flows along a path is monitored relative to a threshold. Here, each data flow is associated with a flow identifier. Based on detection that the congestion level exceeds the threshold, the flow identifier of a number (e.g., one or more) of the data flows is changed to a different flow identifier. This change results in the number of the data flows redirected to a different path. In an alternate embodiment, another method is provided for congestion avoidance. In this method, a data flow transmitted along a single path is received, and the data flow is split into multiple micro data flows. A different flow identifier is then assigned to each micro data flow. This change results in the multiple micro data flows distributed along multiple different paths.

    摘要： A fault protection and correction circuit for the control of a power converter is disclosed. An example circuit generates a waveform that drives a switch on or off and controls the power converter. The controller circuit in addition to power factor correction (PFC) circuitry includes a first and a second shut down mode modules, both of them cause the switching to stop. The circuit includes a module for receiving fault events. When a fault occurs, the controller enters the second shut down mode. The controller stays in the second shut down mode if the required current for this mode can be provided by the outside circuitry. Otherwise, the controller enters the first shut down mode that requires less current and subsequently restarts the controller. By modifying the outside circuitry the controller can respond differently to fault events.
