Abstract (en)
[origin: US4812842A] A wireless control device for a large printing machine includes at least one portable hand unit having a transmitter, and a plurality of push buttons for selecting a desired command to be sent to one of a plurality of electronic control units associated with the printing machine. The commands are transmitted, by electromagnetic radiation, such as infrared waves, or by ultrasonic waves, to receiving and decoding units that are connected to each of the control units. To insure that the control units are not inadvertently actuated, signal verification circuiting can be provided. This circuitry enables a signal received by one of the receiving and decoding units to be retransmitted back to the hand unit, where it is compared with the original signal in the transmitter, to insure that the two coincide. A speech analysis system can be employed with the device to enable commands to be entered verbally.
