A method for controlling a personal protection device for a vehicle. The method includes a step of determining a set of control variants for controlling the personal protection device, from a plurality of possible control variants for controlling the personal protection device, using an inaccurate situational value and at least one inaccuracy value, the inaccurate situational value representing a value ascertained using a sensor of the vehicle, and the inaccuracy value defining an inaccuracy of the inaccurate situational value; and a step of selecting a control variant assigned to the inaccurate situational value, from the plurality of possible control variants, as a control variant selected for controlling the personal protection device, if each control variant of the set of control variants is assigned a safety class, which satisfies a safety criterion necessary for controlling the personal protection device.

A steering wheel includes a metal core earthed to a body of a vehicle, an airbag device, an insulator, and a connector. The airbag device includes a bag holder supported by the metal core, wherein the bag holder forms part of a positive electric path connected to a horn device, an airbag coupled to the bag holder by a fastener, and an inflator including a circumferential portion that forms a flange, wherein the flange of the inflator is coupled by the fastener to the bag holder. The insulator insulates the bag holder from at least the flange and the fastener among elements of the airbag device. The connector electrically connects at least the flange, among the flange and the fastener, to the metal core.

A battery system includes battery cells in a housing; and an impact detection circuit including an electrical resistor circuit supported by a plate member that is adjacent the battery cells and including electrical brittle conductors electrically connected in parallel to each other, each electrical brittle conductor is configured to break in response to an impact causing a deformation of the electrical brittle conductor; a voltage source connected to the electrical resistor circuit and configured to apply a voltage to the electrical resistor circuit; and a detector configured to determine at least one of an electrical resistance of the electrical resistor circuit and an electrical current flowing through the electrical resistor circuit, and detect an impact on the battery system based on determining at least one of a resistance increase and an electrical current drop due to breaking of at least one of the electrical brittle conductors.

An electronic assembly with a theft prevention mechanism includes a housing, a circuit board assembly, at least one trigger element, and an airbag assembly. The circuit board assembly is disposed on an inner wall of the housing. The at least one trigger element is disposed on the inner wall of the housing. The airbag assembly is disposed within the housing and includes at least one airbag. In a normal operating state, the at least one airbag presses against the at least one trigger element. A data theft prevention method for an electronic assembly includes generating a trigger signal in response to a detected change in a volume of the at least one airbag and executing a data protecting procedure in response to the trigger signal.
