Abstract: A vehicle steering wheel system is provided. The system includes a steering wheel body with a hub region for attachment to a steering shaft of a vehicle steering system, a steering wheel rim and at least one spoke for attaching the steering wheel rim to the hub region; an electromechanical triggering device for triggering an acoustic output by means of an acoustic warning device of the vehicle, wherein the triggering device has an impact absorber cover and at least one force transducer wherein a force value threshold is predefined for each force transducer, and a wake-up signal is transmitted via the data connection to the evaluation unit if the force value threshold is exceeded by at least one force value, so that the latter changes from the energy-saving mode into the operating mode in which an actuating force value is determined by force value measured by the at least one force transducer.

Abstract: A circuit configuration is provided for controlling the transmitting power of a battery-operated transceiver. A high transmitting power of a mobile transceiver generates a high voltage drop across an internal impedance of the battery which can lead to the device switching off. A reduction in the transmitting power in dependence on the battery voltage is therefore proposed. The battery voltage is thus compared with a reference voltage and a signal representing a nominal transmitting power is correspondingly corrected. The circuit can be integrated in a simple manner with analog components in an IC.
