Device to automatically screen incoming telephone calls, determine the identity of the caller and process the call accordingly
First Claim
1. A system for the automatic identification of telephone callers for use in a conventional telephone system comprising:
- an incoming signal;
an identification code contained within said incoming signal, a unique code having been assigned to each caller;
a receiving telephone station, including call-alerting means;
automatic call-answering means for receiving at said telephone station said incoming signal and establishing an interconnection with an identification processing means for processing said identification code to determine the identity of the caller, said identification means comprising;
signal sampling/conversion means for receiving said identification code and converting the information contained within said code into date bits representing digital words;
display means coupled to said identification means for displaying the identity of the caller, driven by the digital word output of said identification means, and arranged to produce at a single annunciator the identity of each identified caller, at the time said identification code is received.

Abstract
A device which monitors information contained in incoming telephone calls, and which, when attached to or combined with the circuitry of a telephone receiver, will automatically hold and display the identity of the caller while allowing the telephone bell to be rung only at certain times and/or for certain callers. The caller'"'"'s identity can be determined by the called party without personally answering the telephone and without revealing to the caller whether the called party is at home or not. It can be used to automatically screen incoming calls and prevent the reception of calls which are unwanted. Accordingly, it can be used to allow wanted calls to ring the telephone'"'"'s bell and thus, for example, awaken the user at night, while preventing all unwanted calls from disturbing the called party.

6. A system for the automatic identification of telephone callers for use in a telephone system comprising:
-
an incoming signal;
an identification code contained within said incoming signal, a unique code having been assigned to each caller;
a receiving telephone station, including call-alerting means;
call-answering means for receiving at said telephone station said incoming signal;disabling means coupled to said call-alerting means to prevent the operation of said call-alerting means directly by the incoming signal; identification means coupled to said call answering means for processing said identification code to determine the identity of the caller, said identification means comprising;
signal sampling/conversion means for receiving said identification code and converting the information contained within said code into data bits representing digital words;display means coupled to said identification means for displaying the identity of the caller, driven by the digital word output of said identification means, and arranged to produce at a single annunciator the identity of each identified caller, at the time said identification code is received; memory means coupled to said sampling/conversion means and adapted to store digital words therein; programming means for storing selected words within said memory means, said selected words corresponding to the identification codes assigned to callers from which it is desired to receive calls; processing means for comparing the output of said sampling/conversion means with the contents of said memory means to obtain a unique output from said processing means wherein the specific output obtained is determined by the result of said comparison; and means for actuating the alerting means of the receiving station upon the presence of an enabling output from said processing means. - View Dependent Claims (7, 8)

9. A system for the automatic identification of telephone callers for use in a telephone system comprising:
-
an incoming signal;
an identification code contained within said incoming signal, a unique code having been assigned to each caller;
a receiving telephone station, including call-alerting means;
call-answering means for receiving at said telephone station said incoming signal;disabling means coupled to said call-alerting means to prevent the operation of said call-alerting means directly by the incoming signal; identification processing means coupled to said call-answering means for processing said identification code to determine the identify of the caller, said identification processing means comprising;
signal sampling/conversion means for receiving said identification code and converting the information contained within said code into digital words;alpha-numeric display means coupled to said identification processing means for displaying the identity of the caller, driven by the digital word output of said identification means, and arranged to produce at a single annunciator the identity of each identified caller, at the time said identification code is received; display decoding means coupled to said display to convert the coded identity of the caller as furnished by said identification means to a decoded format for display; memory means coupled to said sampling/conversion means and adapted to store digital words therein; programming means for storing selected words within said memory means, said selected words corresponding to the identification codes assigned to callers from which it is desired to receive calls, and containing time dependency information providing the time at which each identification code is acceptable; clock means to provide time input signals; processing means coupled to said sampling/conversion means, to said memory means and to said clock means for comparing the output of said sampling/conversion means with the contents of said memory means and said time input signals, to obtain a unique output from said processing means, wherein the specific output obtained is determined by the result of said comparison; means for actuating the alerting means of the receiving station upon the presence of an enabling output from said processing means; message sending means coupled to said call answering means and to said processing means for transmitting one or more selected answering messages to said caller, the content of said message selected and transmitted determined by the specific output obtained from said processing means and corresponding to the content of said identification code contained in said incoming signal; message receiving means coupled to receive said incoming signals and to said message sending means for recording messages transmitted by the caller, in synchronization with the operation of said message sending means.
