    Abstract: In a mass flow sensor having a frame of monocrystalline silicon and a membrane fixed therein, a heating element and, if indicated, temperature-measuring elements are provided on the membrane. A heat-conducting element, which extends from the membrane across the frame, is provided in the edge area of the membrane. The heating element, the heat-conducting element and, if indicated, temperature-measuring elements are patterned out of a single metal layer.

    Abstract: A flow sensor has a diaphragm and a resistive film positioned on the diaphragm. A heater is formed from the resistive film and temperature sensors are arranged on both sides of the heater. On both sides of the heater are additional temperature sensors, which are interconnected by an interconnect resistor and formed from the resistive film.

    Abstract: A device is disclosed for crankshaft-synchronous detection of a periodically changing variable of an internal combustion engine, for example the load, which is measured by a sensor whose output signal which is preprocessed or filtered in a suitable fashion is sensed with a selectable timing pattern. The start of sampling is resynchronized for each segment, the signal of a CA sensor being used for synchronization, the said CA sensor sensing a disc connected to the crankshaft and outputting one signal edge per segment. The combination for crankshaft-synchronous sampling with constant timing with respect to the segment permits the use of different load detection sensors with improved accuracy in comparison with previously used methods. The average value of the load for each segment can be determined from the sampled measured values and the quantity of air inducted per power cycle can also be determined.
