Abstract

Abstract The identity of an individual (known or unknown) is determined by a sonic profile of sounds issued through his oral-nasal passages. The sounds are converted to digital electrical signals and produce a three domain format of frequency, amplitude and time samples to produce an array of peaks and valleys constituting the sonic profile of an individual. A source or library of a sonic profiles in the same format of a known individual have the interrelationship including relative positions of said peaks and valleys of said sonic profile of the known individual with that of said unknown individual compared and a utilization signal is provided upon a detecting or non-detecting a correlation between said sonic profiles.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 141 words
A method of identifying an unknown individual comprising: transducing sounds produced by the oral-nasal cavity of a human to first digital electrical signals and deleting therefrom digital electrical signals corresponding to audible portions of said sounds to produce second digital electrical signal corresponding to inaudible portions of said sounds, converting said second digital electrical signals to a three domain format of frequency, amplitude and time samples to produce an array of peaks and valleys constituting a sonic profile of said unknown individual, providing a source of a sonic profile in the same format of a known individual, and comparing the interrelationship including relative positions of said peaks and valleys of said sonic profile of said known individual with the sonic profile of said unknown individual, and providing a utilization signal upon a detecting or non-detecting a correlation between said sonic profiles.
Claim 2
Independent Claim 141 words
A method of identifying an unknown individual comprising: transducing sounds produced by the oral-nasal cavity of a human to first digital electrical signals and deleting therefrom digital electrical signals corresponding to audible portions of said sounds to produce second digital electrical signal corresponding to inaudible portions of said sounds, converting said second digital electrical signals to a three domain format of frequency, amplitude and time samples to produce an array of peaks and valleys constituting a sonic profile of said unknown individual, providing a source of a sonic profile in the same format of a known individual, and comparing the interrelationship including relative positions of said peaks and valleys of said sonic profile of said known individual with the sonic profile of said unknown individual, and providing a utilization signal upon a detecting or non-detecting a correlation between said sonic profiles.
Claim 3
Dependent Claim 29 words
The method defined in claim 1 wherein only a fraction of a second of said second digital electrical signals of each sonic profile is required to form said comparing.
Claim 4
Dependent Claim 17 words
The invention defined in claim 1 wherein said time samples are less than an entire spoken word.
Claim 5
Dependent Claim 18 words
The invention defined in claim 3 wherein said time sample is as short as 1/100 of a second.
Claim 6
Dependent Claim 17 words
The invention defined in claim 1 wherein said sounds which are converted are in the sub-sonic range.
Claim 7
Dependent Claim 14 words
The invention defined in claim 1 wherein said sounds are in the infrasonic range.
Claim 8
Dependent Claim 150 words
Apparatus for identifying an unknown individual comprising: means for transducing sounds produced by the oral-nasal cavity of a human to first digital electrical signals and detecting therefrom electrical signals corresponding to the audible portion of said sounds to produce second digital signals corresponding to the inaudible portions of said sounds, means for converting said second digital electrical signals to a three domain format of frequency, amplitude and time samples to produce an array of peaks and valleys constituting a sonic profile of said unknown individual, means for providing a source of a sonic profile in the same format of a known individual, an means for comparing the interrelationship including relative positions of said peaks and valleys of said sonic profile of said known individual with that of said sonic profile of said unknown individual, and providing a utilization signal upon a detecting or non-detecting a correlation between said sonic profiles.
Claim 9
Dependent Claim 150 words
Apparatus for identifying an unknown individual comprising: means for transducing sounds produced by the oral-nasal cavity of a human to first digital electrical signals and detecting therefrom electrical signals corresponding to the audible portion of said sounds to produce second digital signals corresponding to the inaudible portions of said sounds, means for converting said second digital electrical signals to a three domain format of frequency, amplitude and time samples to produce an array of peaks and valleys constituting a sonic profile of said unknown individual, means for providing a source of a sonic profile in the same format of a known individual, an means for comparing the interrelationship including relative positions of said peaks and valleys of said sonic profile of said known individual with that of said sonic profile of said unknown individual, and providing a utilization signal upon a detecting or non-detecting a correlation between said sonic profiles.
Claim 10
Dependent Claim 29 words
The apparatus defined in claim 7 wherein only a fraction of a second of said second digital electrical signals of each sonic profile is required to form said comparing.
Claim 11
Dependent Claim 17 words
The invention defined in claim 7 wherein said time samples are less than an entire spoken word.
Claim 12
Dependent Claim 18 words
The invention defined in claim 7, wherein said time sample is as short as 1/100 of a second.
Claim 13
Dependent Claim 17 words
The invention defined in claim 7 wherein said sounds which are converted are in the sub-sonic range.
Claim 14
Dependent Claim 14 words
The invention defined in claim 7 wherein said sounds are in the infrasonic range.
