A sensor system includes a quantum dot including one or more paramagnetic centers. It comprises a control and evaluation device including a pump radiation source, a radiation receiver and which irradiates the quantum dot depending on a transmission signal. The quantum dot emits fluorescence radiation upon irradiation with the pump radiation, which depends on the magnetic flux density and/or on another physical parameter.

A method for identifying bus nodes in a bus system makes it possible to be able to operate bus slaves of two different types in mixed systems. The detection of which bus slave has not yet been allocated an address in an addressing phase is carried out differently depending on a type of the bus slave. In all cases, however, the bus slave connected to the bus line farthest away from the bus master is identified as that bus slave to which an address is to be allocated.

A bus node is capable of performing a method, for the assigning of bus node addresses to bus nodes of a serial data bus.

The bus node is characterized by a bus shunt bypass switch which, prior to assigning a bus node address to the bus node in the assignment time period is opened and which after the assignment of bus node address to the bus node in the assignment time period is closed, and which is closed in the operating time period.

Method and sensor system for measuring the transmission properties of a first transmission path based on feedback compensation between a first transmitter and a receiver, a compensation signal of a compensation transmitter being received in a superimposed manner in the receiver in addition to the emitted transmission signal of the first transmitter. A supply signal for the first transmitter and a receiver output signal each form a vector in a pre-Hilbert space. A Hilbert projection is performed between the receiver output signal and the supply signal so that a projection image signal is generated. An output signal is formed from the projection image signal. A pre-signal is generated by an inverse transformation of the output signal with the supply signal. A compensation signal for supplying the compensation transmitter is generated from the pre-signal formed in order to achieve feedback control of the receiver output signal.
