Abstract
At least one actuating element emits a signal in response to blowing and/or suction airflow from a person and is connected to a mouthpiece, and is coupled by way of an evaluation circuit to the appliance to be controlled. In order to maximize the total number of possible combinations of control signal and/or control data, two position transmitters (X-pos, Y-pos) are coupled to further inputs of the evaluation circuit, which incorporates at least one microprocessor, and, when the mouthpiece is used, each transmitter emits a coordinate signal characteristic of the position of the mouthpiece in a coordinate system. The microprocessor is adapted to process the signals from the actuating element, which is in the form of an impact pressure transducer and also the coordinate signals from the position transmitters (X-pos, Y-pos) to produce control data for the appliance.
