Abstract
Abstract A silent communications system in which nonaural carriers, in the very low or very high audio frequency range or in the adjacent ultrasonic frequency spectrum, are amplitude or frequency modulated with the desired intelligence and propagated acoustically or vibrationally, for inducement into the brain, typically through the use of loudspeakers, earphones or piezoelectric transducers. The modulated carriers may be transmitted directly in real time or may be conveniently recorded and stored on mechanical, magnetic or optical media for delayed or repeated transmission to the listener.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
84 words
A silent communications system, comprising: (a) amplitude modulated carrier means for generating signals located in non-aural portions of the audio and in the lower portion of the ultrasonic frequency spectrum said signals modulated with information to be perceived by a listener's brain and, (b) acoustic and ultrasonic transducer means for propagating said signals, for inducement into the brain, of the listener, and, (c) recording means for storing said modulated signals on mechanical, magnetic and optical media for delayed or repeated transmissions to the listener.
Claim 2
Dependent Claim
84 words
A silent communications system, comprising: (a) amplitude modulated carrier means for generating signals located in non-aural portions of the audio and in the lower portion of the ultrasonic frequency spectrum said signals modulated with information to be perceived by a listener's brain and, (b) acoustic and ultrasonic transducer means for propagating said signals, for inducement into the brain, of the listener, and, (c) recording means for storing said modulated signals on mechanical, magnetic and optical media for delayed or repeated transmissions to the listener.
Claim 3
Dependent Claim
84 words
A silent communications system, comprising: (a) frequency modulated carrier means for generating signals located in non-aural portions of the audio and in the lower portion of the ultrasonic frequency spectrum, said signals modulated with information to be perceived by a listener's brain, and; (b) acoustic and ultrasonic transducer means for propagating said signals, for inducement into the brain of the listener, and; (c) recording means for storing said modulated signals on mechanical, magnetic and optical media for delayed or repeated transmissions to the listener.
Claim 4
Dependent Claim
84 words
A silent communications system, comprising: (a) frequency modulated carrier means for generating signals located in non-aural portions of the audio and in the lower portion of the ultrasonic frequency spectrum, said signals modulated with information to be perceived by a listener's brain, and; (b) acoustic and ultrasonic transducer means for propagating said signals, for inducement into the brain of the listener, and; (c) recording means for storing said modulated signals on mechanical, magnetic and optical media for delayed or repeated transmissions to the listener.
Claim 5
Dependent Claim
88 words
A silent communications system, comprising: (a) a combination of amplitude and frequency modulated carrier means for generating signals located in non-aural portions of the audio and in the lower portion of the ultrasonic frequency spectrum, said signals modulated with information to be perceived by a listener's brain, and (b) acoustic and ultrasonic transducer means for propagating said signals, for inducement into the brain of the listener; (c) recording means for storing said modulated signals on mechanical, magnetic and optical media for delayed or repeated transmissions to the listener.
