In the circuit arrangement two of the four vertical transistors are complementary to the remaining two transistors. Two of the transistors are respectively arranged at the same level. For this purpose, layer structures (St1, St2, St3, St4) are structured that respectively have at least a channel layer and a source/drain region of one of the transistors. All the layer structures (St1, St2, St3, St4) can be produced from a layer sequence with only four layers. In order to avoid leakage currents due to a parasitic bipolar transistor, the layer structures (St1, St2, St3, St4) can be realized very thinly, using spacer-type masks. Electrical connections between parts of the four transistors can take place via layers of the layer sequence. The contacting to the output voltage terminal can take place via a step that is formed by two layers of the layer sequence.

In a method for suppressing interference in a controlled variable in a control circuit, in which the actuating variable is the useful signal, the controlled variable is detected continuously, at two successive sampling instants in each case, the values of the controlled variable are subtracted, and if the absolute amount of the difference deviates by a predefinable setpoint value, at least one control parameter is modified, in such a way that the response of the actuating variable to the interference is minimized.

The invention relates to a method for the controlled operation of an industrial oven which is heated in a regenerative manner and which comprises an oven chamber, in particular a melting tank, in particular for glass, having the following steps: injecting fuel into the oven chamber via at least one fuel injector, which is designed to inject fuel, practically without combustion air in particular, conducting combustion air to the oven chamber in a first period duration and conducting exhaust gas (AG) out of the oven chamber in a second period duration separately from the fuel in a periodically alternating manner by means of a left regenerator and right regenerator which are associated with the at least one fuel injector and which are designed to regeneratively store heat from the exhaust gas and transmit heat to the combustion air. A supply of the combustion air is automatically controlled by means of a control loop. The control loop takes into account an excess air coefficient that is specified in the method as well as the location of the entrance of the excess air upstream, in, or downstream of the air-side regenerator. A corresponding control device and an industrial oven which comprises such a control device and which is heated in a regenerative manner are likewise claimed.

According to one general aspect, a method of transportation management may include receiving a request to transport a current freight unit from a current source location to a current destination location. The method may include selecting a prior shipment path based upon a similarity, as defined by a set of predefined criteria, between the current freight unit and a prior freight unit. The method may further include initializing a shipment path improver with the prior shipment path. The method may also include generating, via the shipment path improver, a current shipment path for the current freight unit from the current source location to the current destination location based upon the prior shipment path.
