A sensor unit is described, in particular an air quality sensor, having a first support element, on which are arranged a first sensor element and a first heat source, assigned to the latter, and having at least one further, second support element, on which are arranged a second sensor element and a second heat source, assigned to the latter. The two support elements are configured as a common support unit and, between them, have a heat barrier for thermal isolation.

Sensor unit for air quality measurement

A method of operating a resistance heating element and a device for carrying out the method are described. During a first step, the resistance of a resistor of the resistance heating element is determined at a known base temperature. In a second step, the resistance setpoint value is determined as a function of resistance of the resistor at the known base temperature and known temperature coefficients. The resistance heating element is activated by approximately setting the resistance setpoint value in order to heat the resistance heating element to the given setpoint temperature.

Circuit arrangement and method for operating an adjusting device

A method of making a device for establishing an electric contact with conductors of an electric apparatus includes the following steps: forming a one-piece leadframe from sheet metal; securing the leadframe pattern to an electrically insulating carrier; severing the conductor into individual conductor strips; mounting an electric and/or electronic component on the carrier; and electrically contacting the components with selected conductor strips.

Electric motor drive

A device for detecting the movement of a movable component in that the position signals furnished by two position sensors are added to form a signal that is conducted through a line to an evaluation arrangement. The position ranges associated with the position sensors have an overlap region. Different discrete values are assigned to the position signals and can be evaluated easily in the evaluation arrangement.

A network interface, in particular for motor vehicles having at least two computers and having at least two bus lines ('0') includes by a monitoring circuit (100), which cooperates with an evaluation circuit to detect the operativeness of the bus lines and identify a faulty bus line and an emergency circuit (210,215) controlled by the monitoring circuit to connect the faulty bus line to an emergency potential. Even in the event of a short circuit, to the supply voltage U.sub.B or earth, of one of the bus lines connected to a terminating unit (OP1,R3; OP2,R4) or in the event of a defective driver stage (T10,T20) of a network substation connected to the bus lines, it is still possible to operate the comparator (K) of a receiver or signal evaluation circuit even with only one operational bus line. In this way, a particularly high operational reliability of the network interface is obtained.

Network interface

A protective device for electric motors for protecting electric motors from high operational temperatures, has an element for determining an operational temperature of an electric motor and an element for automatically switching off of the electric motor when a predetermined limiting operational temperature is exceeded. The determining element is formed as electronic element for determining the operational temperature indirectly from an at least another operational parameter of the electric motor. The element for automatically switching off is formed as electronic element for automatically switching off of the electric motor.

A monitoring device for an electronic control system in a motor vehicle is advantageously integrated with a digital signal processing device (43) of the system. Economy in terms of components and greater operational reliability safety are attained in that the monitoring of a circuit arrangement of the system is performed sequential plausibility tests of signals that are retrievable at various times from fixed points of one and the same circuit arrangement, which is alternated by the digital signal processing device between an operating state and a test state.
