Abstract: Battery pack having at least one battery cell arranged within a housing, and a sensor arrangement arranged between the battery cell and an abutting surface. The sensor arrangement has first and second carrier foils separated by a spacer having a recess. A contact arrangement having first and second electrodes are arranged on the respective first and second carrier foils at the recess. In the operating state, the first electrode is spaced apart a first distance from the second electrode and, in a deformation state, a deformation of the battery cell is detected by a variation of an electrical property of the contact arrangement. The second carrier foil has an inlay having a second recess accommodating an activator unit arranged on the second carrier foil such that, after a transition from the operating state in the deformation state, a pressure force is transmitted via the activator unit.

Abstract: A system for capacitive object detection. In order to provide means for efficiently using the circuitry of an electrical heating device for capacitive object detection, the system includes: an elongate conductive element extending between a first terminal and a second terminal, wherein the first terminal is coupled to ground via a capacitive element and is connectable to an electrical power source, and the second terminal is connected to ground; and a detection circuit connected to at least one detection node disposed on the conductive element between the first and second terminal. The detection circuit is adapted to capacitively detect the presence of an object in the proximity of the conductive element based on an impedance associated with the object.

Abstract: A capacitive detection device includes a capacitive sensor having a sense electrode and an auxiliary electrode that are arrangeable in the vicinity of an electric heater member for mutual capacitive coupling. The capacitive detection device has a signal voltage source providing an alternating measurement voltage, a complex impedance measurement circuit for measuring complex sense currents and for determining a complex impedance based on the measured complex sense current, and for electrically connecting the auxiliary electrode either with the reference voltage or with the guard signal. The method includes providing the measurement signal to the sense electrode and electrically connect the auxiliary electrode selectively either to the reference voltage or to the guard voltage; determining capacitance values in the two different connection states of the auxiliary electrode; and calculating a compensated capacitance value as a weighted sum of the two determined capacitance values, wherein the weighting factors are predefined constant values.

Abstract: An occupancy detection system for at least one vehicle seat includes: an antenna arrangement having an antenna; a control device that applies a radio-frequency transmission signal to, and receives a response signal from, the antenna arrangement; and a transmit array having a plurality of structured metallic layers disposed above each other and extending laterally, each two neighbouring metallic layers isolated from each other by an intermediate dielectric layer. The antenna arrangement transmits a radio-frequency transmission field through the transmit array onto the vehicle seat in response to the transmission signal and receives a radio-frequency response field through the transmit array to generate the response signal. The transmit array is adapted to refract at least one of the transmission field and the response field. The transmit array has a receive section that focuses a response field from a position of a vehicle seat to a position of a receive antenna.
