Method for controlling graphical systems such as printing machines

摘要

The system has transmitter and receiver module (2) for handling acoustic communication signals from a user's voice and is coupled to hardware (1) that suppresses noise and provides an analogue output. A generated pulse signal is superimposed and the modulated signal is received and demodulated followed by processing (3) and input to a speech interpreter (5), a verifier (6), and a logic device (7). The electric signal is transferred in a wireless manner and compared with prespecified values on a personal computer. A corresponding signal is then generated to control the function of the machine.
