Abstract: A capacitive sensor device for detecting the presence of a human body part in a detection region of the sensor device is disclosed. The sensor device includes a first sensor electrode with a first electrode section, a second sensor electrode with a second electrode section, and a measuring device for ascertaining a measurement variable, which is based on a current difference between a first current flowing in the first electrode section of the at least one first sensor electrode and a second current flowing in the second electrode section of the second sensor electrode. The measuring device has an electric coil, and the first electrode section of the first sensor electrode and the second electrode section of the second sensor electrode are at least partly arranged relative to each other and relative to the coil in each case and are coupled to the coil.

Abstract: The present invention relates to a combined capacitive sensor and heating apparatus (10, 60, 70) having a capacitive sensor device for detecting the presence of a capacitively effective actuation means in a detection region of the sensor device, and having a heating device, wherein the sensor and heating apparatus (10, 60, 70) has an electrical combined sensor and heating element (4), wherein a synchronization device (40) is configured to capture an actual voltage applied to the first electrical path (P1) between the first pole (V+) of a voltage source and the first connection (5) of the combined sensor and heating element (4) and/or an actual current flow and/or to capture an actual voltage applied between the second connection (6) of the combined sensor and heating element (4) and the second pole (GND) and/or an actual current flow and to detect an instantaneous actual state of the heating device on the basis thereof, and to control the sensor device and/or output at least one control signal for at least pa

Abstract: The invention relates to a steering device, especially for vehicles, comprising a rotatable steering wheel and a base that cannot be rotated relative to the steering wheel, and means for transmitting data between the steering wheel and the base. The invention is especially characterized in that the means are configured in such a manner that they transmit the data in the form of light signals between the steering wheel and the base in a non-contact manner.
