Claims (2)

1. Funkgesteuerte Audiostummschaltung im Kraftfahrzeug, die dadurch gekennzeichnet ist, dass
  • - in verschiedenen Einsatzfahrzeugen (Rettungswagen, Feuerwehr, Polizei) ein Sender eingebaut ist.
1. Radio-controlled audio muting in the motor vehicle, which is characterized in that
  • - A transmitter is installed in various emergency vehicles (ambulance, fire brigade, police).
2. Funkgesteuerte Audiostummschaltung im Kraftfahrzeug, die dadurch gekennzeichnet ist, dass der Autoradio
  • - um eine Zeiteinheit (1) ergänzt ist, die aus der Autoradiobetriebsspannung (+12Va) über ihr integriertes Relais [bzw. Transistor] (3) die Betriebsspannung (+12Vb) für das gesamte System zur Verfügung stellt.
  • - um einen Taster (2) ergänzt ist, der das System für eine gewisse Zeit deakti­ viert.
  • - um eine Leuchtdiode (4) [oder Anzeige im Display des Gerätes] ergänzt ist, die das aktivierte System anzeigt.
  • - um einen Empfängerbaustein (6) ergänzt ist, der das Eingangssignal decodiert und an das Schaltmodul weitergibt.
  • - um ein Schaltmodul (7) ergänzt wird, das die Systembetriebsspannung auf die Zeiteinheit II (9) schaltet.
  • - um eine weitere Zeiteinheit (9) ergänzt wird, die mithilfe zweier Transistoren die Endstufe stummschaltet.
  • - um eine blinkende Leuchtdiode (14) [oder Anzeige im Display des Gerätes] ergänzt ist, die die Stummschaltung anzeigt.
2. Radio-controlled audio muting in the motor vehicle, which is characterized in that the car radio
  • - A time unit (1) is added, which from the car radio operating voltage (+ 12Va) via its integrated relay [or Transistor] (3) provides the operating voltage (+ 12Vb) for the entire system.
  • - A button (2) is added, which deactivates the system for a certain time.
  • - A light-emitting diode (4) [or display on the device] is added, which shows the activated system.
  • - A receiver module (6) is added, which decodes the input signal and passes it on to the switching module.
  • - A switching module (7) is added, which switches the system operating voltage to the time unit II (9).
  • - Another time unit (9) is added, which mutes the output stage using two transistors.
  • - A blinking light-emitting diode (14) [or indication on the display of the device] is added to indicate the muting.
