Abstract: An active three-wire fluid level sensor employed in an application designed for a two-wire switch is disclosed. A fluid level sensor assembly includes a fluid level sensor including first, second, and third wires. The third wire carries an output signal configured to fluctuate between a low output signal level and a high output signal level. The fluid level sensor assembly also includes a supply modulation driver electrically connected to the third wire. The fluid level sensor, via the first, second, and third wires, is configured to serve as an input to a two-wire input electronic control unit (ECU). A method of operating a two-wire circuit function by supply modulation is also disclosed.

Abstract: A magnetic field device determines external magnetic influence. The device has a component with ferromagnetic material. The component has one or more magnetizable tracks arranged adjacent to each other having opposing directions of magnetization and arranged axially in relation to the component. A first magnetic field sensor is arranged radially in relation to the component and is assigned to the two tracks. A second magnetic field sensor is arranged radially in relation to the component and is assignable to two magnetisable tracks. The signal of each of the magnetic field sensors is set in relation to the signal of the at least one another magnetic field sensor. The signals produced by the magnetic field sensors form at least one individual signal channel. The first and second magnetic field sensors are combined with each other axially along the direction of magnetization of the assigned magnetic track to form the signal channel.
