Human body comparison using driving point parameters
First Claim
1. A method for comparing a subsequently interrogated person with a previously interrogated person, the method comprising:
- (a) applying non-impulsive, physical vibration wave energy to a selected driving point on a human body at a plurality of frequencies to generate force and motion variations at said driving point;
(b) detecting a first set of data, while said wave energy is being applied, which data represents at least one of said variations as a function of time at said driving point;
(c) storing said first set of data;
(d) subsequently applying non-impulsive, physical vibration wave energy to a subsequent, corresponding driving point on a human body at a plurality of frequencies to generate subsequent force and motion variations at said subsequent driving point;
(e) detecting a second set of data, while said wave energy is being applied, said second set of data representing at least one of said subsequent variations as a function of time at said subsequent driving point; and
(f) comparing said first set of data with said second set of data to determine whether they are within selected tolerances of each other.

Abstract
An apparatus and method suitable for automatic machine interrogation of individuals for identifying or analyzing persons such as those seeking admittance to secure areas or seeking an extension of credit. Physical vibration wave energy is applied by a signal generator and transducer to the person'"'"'s body at a selected point such as the finger tips. The frequency and/or the time function of force and/or motion parameters at the driving point of the body are then detected and stored. Comparison of a previously known function with a subsequently measured function to determine whether they are within preselected tolerances permits a machine decision whether the functions represent the same person.

23. An apparatus for comparing a subsequently interrogated person with a previously interrogated person, said apparatus comprising:
-
(a) means for applying non-impulsive, physical vibration wave energy to a selected driving point on a human body at a plurality of frequencies to generate force and motion variations at said driving point; (b) means for detecting a set of data representing at least one of said variations as a function of time or frequency at said driving point; (c) means for storing said data; and (d) means for comparing data detected at a first time at said driving point to data detected at a subsequent time at a corresponding driving point to determine whether said sets of data are within selected tolerances of each other. - View Dependent Claims (24, 25)
