1. AN AUTOMATIC EMERGENCY ASSITANCE-CALLING COMMUNICATIONS SYSTEM COMPRISING IN COMBINATION:
- A FIRST RADIO TRANSMITTER OF SUCH PROPORTIONS AND CONFIGURATION AS TO BE CONCEALABLE ON ONE'"'"''"'"'S PERSON, SAID FIRST TRANSMITTER INCLUDING A FREQUENCY-CONTROLLED, RADIO-FREQUENCY SIGNAL GENERATOR, A MULTIVIBRATOR AUDIO-FREQUENCY SIGNAL GENERATOR, ELECTRIC CIRCUIT MEANS CCOUPLING SAID AUDIO-FREQUENCY GENERATOR TO SAID RADIO-FREQUENCY GENERATOR FOR MODULATION OF SAID RADIO-FREQUENCY GENERATOR WITH AUDIO FREQUENCY SIGNALS OF PREDETERMINED CHARACTER, AND SWITCH MEANS, COUPLED TO SAID TRANSMITTER, AND ADAPTED TO BE MANUALLY OPERATIVE FOR ACTUATING SAID FIRST RADIO TRANSMITTER WHEN AN EMERGENCY THREATENS THE ONE WHO MAINTAINS SAID TRANSMITTER ON HIS PERSON;
A FIRST RADIO RECEIVER, ADAPTED TO BE RESPONSIVE TO THE MODULATED SIGNALS TRANSMITTED BY SAID FIRST RADIO TRANSMITTER, AND INCLUDING CIRCUIT MEANS THEREIN ADAPTED TO RECEIVE AND DEMODULATE THE MODULATED RADIO-FREQUENCY SIGNALS TRANSMITTED BY SAID FIRST TRANSMITTER AND FOR DERIVING THEREFROM A SWITCHING CONTROL SIGNAL;
A SECOND RADIO TRANSMITTER HAVING THEREIN A FIRST SOURCE OF MODULATING SIGNALS IN THE FORM OF A SPEECH MODULATOR AND A SECOND SOURCE OF MODULATING SIGNALS IN THE FORM OF A PREDETERMINED CODE SIGNAL GENERATOR FOR IDENTIFYING THE PARTICULAR SECOND RADIO FREQUENCY TRANSMITTER BY THE PREDETERMINED CODE SIGNAL, AND SWITCHING CIRCUIT MEANS COUPLED WITH SAID FIRST RECEIVER AND ADAPTED TO BE RESPONSIVE TO SAID SWITCHING CONTROL SIGNALS TO TRANSFER SAID SECOND TRANSMITTER FROM SAID SPEECH MODULATION SOURCE TO SAID SECOND SOURCE OF MODULATING SIGNALS FOR TRANSMITTING A CARRIER SIGNAL MODULATED BY SAID PREDETERMINED CODE SIGNAL;
AND A SECOND RADIO RECEIVER LOCATED IN A CENTRAL STATION AND INCLUDING THEREIN A CHARACTERISTIC DISPLAY INDICATOR ADAPTED TO BE RESPONSIVE TO SAID PREDETERMINED CODE SIGNAL MODULATING THE CARRIER OF SAID SECOND TRANSITTER AND BEING RECEIVED BY SAID SECOND RADIO RECEIVER, SAID DISPLAY INDICATOR BEING FURTHER ADAPTED TO DISPLAY AN IDENTIFYING INDICATION CHARACTERISTIC OF THE PARTICULAR PREDETERMINED CODE SIGNAL BEING RECEIVED FROM THAT PARTICULAR SECOND TRANSMITTER, SAID DISPLAY BEING AN INDICATION OF THE NEED FOR ASSISTANCE AND THE LOCATION OF THE ONE NEEDING ASSISTANCE WHEREUPON IMMEDIATE AID CAN BE DISPATCHED FROM SAID CENTRAL STATION.
