Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
109 words
A method for causing a plurality of telephones to transmit a predetermined telephone number, comprising modulating a public broadcast signal with a DTMF signal corresponding to said predetermined telephone number; broadcasting said modulated public broadcast signal for receipt by a plurality of receivers each having an audio frequency transducer; demodulating said modulated public broadcast signal the immediately generator a sequence of DTMF audible tones corresponding to said telephone number immediately upon receipt of said modulated broadcast signal and immediately radiating said sequence of DTMF audible tones from said transducer so that a telephone receiving said sequence of audible tones will transmit said telephone number into a public telephone system.
Claim 2
Independent Claim
109 words
A method for causing a plurality of telephones to transmit a predetermined telephone number, comprising modulating a public broadcast signal with a DTMF signal corresponding to said predetermined telephone number; broadcasting said modulated public broadcast signal for receipt by a plurality of receivers each having an audio frequency transducer; demodulating said modulated public broadcast signal the immediately generator a sequence of DTMF audible tones corresponding to said telephone number immediately upon receipt of said modulated broadcast signal and immediately radiating said sequence of DTMF audible tones from said transducer so that a telephone receiving said sequence of audible tones will transmit said telephone number into a public telephone system.
Claim 3
Dependent Claim
24 words
The method of claim 1 further comprising recording said DTMF signal and thereafter using said recorded DTMF signal to modulate said public broadcast signal.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said public broadcast signal is a radio signal.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein said public broadcast signal is a television signal.
Claim 6
Dependent Claim
20 words
The method of DTMF claim 1 wherein said sequence of audible tones is generated by said plurality of receivers simultaneously.
Claim 7
Independent Claim
118 words
A method for causing a plurality of telephones to transmit a predetermined telephone number, comprising modulating a public broadcast signal with a DTMF signal corresponding to said predetermined telephone number; broadcasting said modulated public broadcast signal for receipt by a plurality of television or radio sets each having an audio frequency transducer; demodulating said modulated public broadcast signal to immediately generate a sequence of DTMF audible tones corresponding to said telephone number by said television or radio sets and immediately radiating said sequence of DTMF tones from said transducer so that a telephone receiving said sequence of DTMF audible tones from one of said television or radio sets will transmit said telephone number into a public telephone system.
Claim 8
Independent Claim
118 words
A method for causing a plurality of telephones to transmit a predetermined telephone number, comprising modulating a public broadcast signal with a DTMF signal corresponding to said predetermined telephone number; broadcasting said modulated public broadcast signal for receipt by a plurality of television or radio sets each having an audio frequency transducer; demodulating said modulated public broadcast signal to immediately generate a sequence of DTMF audible tones corresponding to said telephone number by said television or radio sets and immediately radiating said sequence of DTMF tones from said transducer so that a telephone receiving said sequence of DTMF audible tones from one of said television or radio sets will transmit said telephone number into a public telephone system.
Claim 9
Dependent Claim
31 words
The method of claim 6 wherein said modulated public broadcast signal is demodulated and said sequence of DTMF audible tones is generated immediately upon receipt of said modulated public broadcast signal.
Claim 10
Dependent Claim
24 words
The method of claim 6 further comprising recording said DTMF signal and thereafter using said recorded DTMF signal to modulate said public broadcast signal.
Claim 11
Dependent Claim
14 words
The method of claim 6 wherein said public broadcast signal is a radio signal.
Claim 12
Dependent Claim
14 words
The method of claim 6 wherein said public broadcast signal is a television signal.
Claim 13
Dependent Claim
23 words
The method of claim 6 wherein said sequence of DTMF audible tones is generated by said plurality of television or radio sets simultaneously.
Claim 14
Independent Claim
117 words
A method for causing a plurality of telephones to transmit a predetermined telephone number, comprising modulating a public broadcast signal with a DTMF signal corresponding to said predetermined telephone number; broadcasting said modulated public broadcast signal for receipt by a plurality of receivers each having an audio frequency transducer; demodulating said modulated public broadcast signal and generating a sequence of DTMF audible tones corresponding to said telephone number immeidately upon receipt of said modulated public broadcast signal and immediately radiating said sequence of DTMF audible tones from said transducer so that a plurality of telephones receiving said sequence of DTMF audible tones from said plurality of receivers will transmit said telephone number into a public telephone system.
Claim 15
Independent Claim
117 words
A method for causing a plurality of telephones to transmit a predetermined telephone number, comprising modulating a public broadcast signal with a DTMF signal corresponding to said predetermined telephone number; broadcasting said modulated public broadcast signal for receipt by a plurality of receivers each having an audio frequency transducer; demodulating said modulated public broadcast signal and generating a sequence of DTMF audible tones corresponding to said telephone number immeidately upon receipt of said modulated public broadcast signal and immediately radiating said sequence of DTMF audible tones from said transducer so that a plurality of telephones receiving said sequence of DTMF audible tones from said plurality of receivers will transmit said telephone number into a public telephone system.
Claim 16
Dependent Claim
24 words
The method of claim 12 further comprising recording said DTMF signal and thereafter using said recorded DTMF signal to modulate said public broadcast signal.
Claim 17
Dependent Claim
14 words
The method of claim 12 wherein said public broadcast signal is a radio signal.
Claim 18
Dependent Claim
14 words
The method of claim 12 wherein said public broadcast signal is a television signal.
Claim 19
Dependent Claim
20 words
The method of claim 12 wherein said sequence of DTMF audible tones is generated by said plurality of receivers simultaneously.
