A circuit system for measuring an electrical voltage. The circuit system includes a voltage divider, an integrating element and an evaluating unit. The voltage divider receives, at an input, a first signal that represents the electrical voltage to be measured, and has a first switching element and a second switching element, and is capable of assuming a first state, in which the first switching element is conductive and the second switching element is non-conductive, and a second state in which the first switching element is non-conductive and the second switching element is conductive, and outputs a second signal at an output that is situated between the first switching element and the second switching element. The integrating element is designed to receive the second signal and to output a third signal. The evaluating unit being set up to accept and to evaluate the third signal in order to determine a value for the electrical voltage.

A sensor arrangement is configured to detect rotational angles on a rotating component in a vehicle. The rotating component is coupled to at least one measurement transmitter which generates at least one piece of angle information in connection with at least one measurement sensor in order to determine the rotational angle of the rotating component. A first measurement transmitter and a first measurement sensor form a first angle sensor which generates first angle information that is dependent on the rotational movement of the rotating component, and a second measurement transmitter and a second measurement sensor form a second angle sensor which generates second angle information that is dependent on the rotational movement of the rotating component. A current rotational angle of the rotating component is ascertained from the first angle information and the second angle information. The first angle sensor and the second angle sensor are designed as inductive sensors.

A sensor device for determining the position of a metal body comprising at least one Eddy current sensor, which has a coil for generating a high-frequency electromagnetic alternating field and a device for operating the coil and for detecting an impedance of the coil, and comprising an analyzing device, which determines the position of the metal body relative to the coil using the detected impedance. A reference Eddy current sensor is provided which has a reference coil for generating a high-frequency electromagnetic alternating field and a reference device for operating the reference coil and for detecting an impedance of the reference coil and which is oriented/designed such that the electromagnetic alternating field of the reference Eddy current sensor is free of metal bodies, wherein the analyzing device is designed to form a beat from the detected impedance and to determine the position of the metal body dependent on the beat.

An electrical circuit for transmitting signals between two masters and one or more slaves is described. The two masters and the slave or slaves are connected to one another via a bus system. At least one master data signal can be generated by each of the two masters, which signal can be received by the slave or slaves. A three-state gate is present at each of the outputs of the two masters at which the respective master data signal is present. The three-state gates are effective either as closed or as open switches. The three-state gates are activated in such a way that the three-state gate associated with the one of the two masters acts as a closed switch, and the three-state gate associated with the other of the two masters acts as an open switch.

A sampling method is for an asynchronous sensor, in which sensor data are read out from a sensor element at a sampling rate and written into an output register and subsequently read out from the output register at an output rate. The output rate of the output register is increased by a programmable interpolation of at least two sampling values.
