A circuit comprises a mechanical relay and a solid-state relay. The mechanical relay is configured to switch a first supply current of the first heating element on a first supply line. The solid-state relay is configured to switch a second supply current of a second heating element on a second supply line.

Mechanical relay and solid-state relay for controlling heating elements

A system including a first electrode, a second electrode, a first circuit and a second circuit. The second electrode is capacitively coupled to the first electrode. The first circuit is configured to receive data via a network and transmit a signal via the first electrode based on the data. The second circuit is configured to receive data via the network and receive a current that corresponds to the signal via the second electrode based on the data.

System including capacitively coupled electrodes and circuits in a network

Embodiments of the present invention relate generally to an electronic control unit for an airbag, said control unit having a data recorder unit that has a volatile memory, a nonvolatile memory and a copy circuit. The copy circuit is designed to copy data from the volatile memory to the nonvolatile memory during a second operating phase of the control unit. A protocol unit designed to record vehicle and/or accident data in the volatile memory is arranged in the data recorder unit during a first operating phase of the control unit. A first power supply unit is connected to the control unit and supplies the protocol unit and further components of the control unit with power and a second power supply unit is connected to the data recorder unit and supplies the latter with power.
