Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
95 words
COMMUNICATIONS APPARATUS FOR AUTOMATICALLY RETRANSMITTING A CARRIER SIGNAL IN THE DIRECTION FROM WHICH IT IS RECEIVED, SAID APPARATUS COMPRISING: AN ANTENNA ARRAY FOR INTERCEPTING THE RECEIVED SIGNAL, THE ANTENNAS IN SAID ARRAY RESPECTIVELY PRODUCING OUTPUT SIGNALS THAT ARE PHASED ACCORDING TO THE SPACINGS BETWEEN THE ANTENNAS AND THE ANGLE OF ARRIVAL OF THE INCIDENT WAVE; NETWORKS RESPECTIVELY COUPLED TO THE ANTENNAS IN SAID ARRAY FOR CIRCULATING THE OUTPUT SIGNALS THEREFROM BACK TO THEIR RESPECTIVE ANTENNAS FOR RETRANSMISSION, SAID NETWORKS RESPECTIVELY INCLUDING CIRCUITS FOR CONVERTING THE INITIAL PHASES OF SAID OUTPUT SIGNALS TO THEIR COMPLEX CONJUGATES.
Claim 2
Dependent Claim

COMMUNICATIONS APPARATUS FOR AUTOMATICALLY RETRANSMITTING A CARRIER SIGNAL IN THE DIRECTION FROM WHICH IT IS RECEIVED, SAID APPARATUS COMPRISING: AN ANTENNA ARRAY FOR INTERCEPTING THE RECEIVED SIGNAL, THE ANTENNAS IN SAID ARRAY RESPECTIVELY PRODUCING OUTPUT SIGNALS THAT ARE PHASED ACCORDING TO THE SPACINGS BETWEEN THE ANTENNAS AND THE ANGLE OF ARRIVAL OF THE INCIDENT WAVE; NETWORKS RESPECTIVELY COUPLED TO THE ANTENNAS IN SAID ARRAY FOR CIRCULATING THE OUTPUT SIGNALS THEREFROM BACK TO THEIR RESPECTIVE ANTENNAS FOR RETRANSMISSION, SAID NETWORKS RESPECTIVELY INCLUDING CIRCUITS FOR CONVERTING THE INITIAL PHASES OF SAID OUTPUT SIGNALS TO THEIR COMPLEX CONJUGATES.
Claim 3
Independent Claim
160 words
A SYSTEM FOR TRANSFERRING INFORMATION BETWEEN TWO DISTANT STATIONS, THE TRANSMISSION TO THE SECOND STATION AUTOMATICALLY BEING ACCOMPLISHED WITH OPTIMUM DIRECTIVITY, SAID SYSTEM COMPRISING: A NUMBER OF ANTENNAS FOR INTERCEPTING A MODULATED FIRST CARRIER SIGNAL RECEIVED FROM THE FIRST STATION AND AN UNMODULATED SECOND CARRIER SIGNAL RECEIVED FROM THE SECOND STATION, SAID ANTENNAS, IN RESPONSE TO THE LATTER SIGNAL, RESPECTIVELY PRODUCING A CORRESPONDING NUMBER OF UNMODULATED SECOND CARRIER SIGNALS THAT ARE PHASED ACCORDING TO THE SPACINGS BETWEEN SAID ANTENNAS AND THE ANGLES OF ARRIVAL OF THE RECEIVED UNMODULATED SECOND CARRIER SIGNAL RELATIVE THERETO; A NUMBER OF NETWORKS ARRANGED TO RESPECTIVELY FEED SAID SECOND CARRIER SIGNALS BACK TO SAID ANTENNAS, SAID NETWORKS RESPECTIVELY INCLUDING CIRCUITS FOR CHANGING THE PHASES OF SAID SECOND CARRIER SIGNALS TO THE COMPLEX CONJUGATES OF SAID SPATIAL PHASES; AND A NUMBER OF ADDITIONAL CIRCUITS RESPECTIVELY COUPLED BETWEEN SAID ANTENNAS AND SAID NETWORKS FOR TRANSFERRING TO SAID SECOND CARRIER SIGNALS THE MODULATION CONTAINED IN SAID FIRST CARRIER SIGNALS.
Claim 4
Independent Claim
160 words
A SYSTEM FOR TRANSFERRING INFORMATION BETWEEN TWO DISTANT STATIONS, THE TRANSMISSION TO THE SECOND STATION AUTOMATICALLY BEING ACCOMPLISHED WITH OPTIMUM DIRECTIVITY, SAID SYSTEM COMPRISING: A NUMBER OF ANTENNAS FOR INTERCEPTING A MODULATED FIRST CARRIER SIGNAL RECEIVED FROM THE FIRST STATION AND AN UNMODULATED SECOND CARRIER SIGNAL RECEIVED FROM THE SECOND STATION, SAID ANTENNAS, IN RESPONSE TO THE LATTER SIGNAL, RESPECTIVELY PRODUCING A CORRESPONDING NUMBER OF UNMODULATED SECOND CARRIER SIGNALS THAT ARE PHASED ACCORDING TO THE SPACINGS BETWEEN SAID ANTENNAS AND THE ANGLES OF ARRIVAL OF THE RECEIVED UNMODULATED SECOND CARRIER SIGNAL RELATIVE THERETO; A NUMBER OF NETWORKS ARRANGED TO RESPECTIVELY FEED SAID SECOND CARRIER SIGNALS BACK TO SAID ANTENNAS, SAID NETWORKS RESPECTIVELY INCLUDING CIRCUITS FOR CHANGING THE PHASES OF SAID SECOND CARRIER SIGNALS TO THE COMPLEX CONJUGATES OF SAID SPATIAL PHASES; AND A NUMBER OF ADDITIONAL CIRCUITS RESPECTIVELY COUPLED BETWEEN SAID ANTENNAS AND SAID NETWORKS FOR TRANSFERRING TO SAID SECOND CARRIER SIGNALS THE MODULATION CONTAINED IN SAID FIRST CARRIER SIGNALS.
