Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
216 words
A system for responding to a condition at a site for selectively dialing the address of a remote station and transmitting through transmission lines a message relating to said condition comprising storage means for storing pulse signals representing the address of said remote station and said message signals, a normally open circuit connected between said storage means and said transmission lines, means responsive to said condition to close said normally open circuit path and to sequentially apply said pulse signals and said message signals from said storage means through said transmission lines, a timing circuit including an integrator circuit responsive to said pulse signals, a bistable circuit for maintaining a closed path between said storage means and said transmission lines, means for applying said pulse signals to actuate said bistable circuit to close the path between said storage means and said transmission lines during a dialing operation, means for applying said pulse signals to said timing circuit to actuate said timing circuit after the transmission of said pulse signals to produce an output signal, means for applying said output signal to said bistable circuit after the transmission of said pulse signals to maintain said open circuit closed to permit the transmission of said message signals through said transmission lines after the transmission of said pulse signals.
Claim 2
Independent Claim
216 words
A system for responding to a condition at a site for selectively dialing the address of a remote station and transmitting through transmission lines a message relating to said condition comprising storage means for storing pulse signals representing the address of said remote station and said message signals, a normally open circuit connected between said storage means and said transmission lines, means responsive to said condition to close said normally open circuit path and to sequentially apply said pulse signals and said message signals from said storage means through said transmission lines, a timing circuit including an integrator circuit responsive to said pulse signals, a bistable circuit for maintaining a closed path between said storage means and said transmission lines, means for applying said pulse signals to actuate said bistable circuit to close the path between said storage means and said transmission lines during a dialing operation, means for applying said pulse signals to said timing circuit to actuate said timing circuit after the transmission of said pulse signals to produce an output signal, means for applying said output signal to said bistable circuit after the transmission of said pulse signals to maintain said open circuit closed to permit the transmission of said message signals through said transmission lines after the transmission of said pulse signals.
Claim 3
Dependent Claim
50 words
The invention as set forth in claim 1, wherein a different circuit path is provided to connect said pulse signals from said storage means to said transmission lines with said timing circuit being responsive to open said different circuit path upon the completion of the transmission of said pulse signals.
Claim 4
Dependent Claim
23 words
The invention as set forth in claim 1 wherein the means responsive to said condition includes a transducer for generating an electrical signal.
Claim 5
Dependent Claim
24 words
The invention as set forth in claim 3 wherein a receiver is provided, said receiver being responsive to electrical signals generated by said transducer.
Claim 6
Dependent Claim
28 words
The invention as set forth in claim 3 wherein a transmitter is provided to transmit signals to said receiver in response to electrical signals produced by said transducer.
Claim 7
Dependent Claim
34 words
The invention as set forth in claim 5 wherein the electrical signals produced by said transducer cause modulation of a carrier frequency of said transmitter, with said modulation involving at least two modulation frequencies.
Claim 8
Dependent Claim
38 words
The invention as set forth in claim 6 wherein a recycling circuit is provided to reset the system to its original state after the transmission of signals relating to the address of said remote station and said message.
Claim 9
Dependent Claim
29 words
The invention as set forth in claim 7 wherein said timing circuit includes a bi-stable circuit responsive to a voltage exceeding a predetermined level developed across a charging circuit.
Claim 10
Dependent Claim
27 words
The invention as set forth in claim 8 wherein a second bi-stable circuit is included in said means responsive to said condition to close said circuit path.
