Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
76 words
The method of analyzing cerebral electrical activity comprising the steps of: sensing the cerebral electrical outputs from selected locations on the head of a living subject; comparing such outputs with more than one adjustable predetermined value; producing signals representing each time any one of said outputs has a value which exceeds any one or more of said adjustable predetermined values; and determining the number of the signals so produced at each of said adjustable predetermined values.
Claim 2
Independent Claim
76 words
The method of analyzing cerebral electrical activity comprising the steps of: sensing the cerebral electrical outputs from selected locations on the head of a living subject; comparing such outputs with more than one adjustable predetermined value; producing signals representing each time any one of said outputs has a value which exceeds any one or more of said adjustable predetermined values; and determining the number of the signals so produced at each of said adjustable predetermined values.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein said last-mentioned step comprises the step of providing a visual indication of said signals.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein said last-mentioned step comprises the step of recording said signals.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein said last-mentioned step comprises the step of counting the number or said signals occurring in discrete time intervals.
Claim 6
Dependent Claim
49 words
The method of claim 1 including the step of comparing said signals with statistically valid groups of similar signals in a memory data storage means to ascertain the degree of correspondence of said signals with any one or more of said groups of signals in the data storage means.
Claim 7
Dependent Claim
36 words
The method of claim 5 wherein said step of comparing said signals with said groups of signals in the data storage means includes the step of transmitting said signals to a remote location for such comparison.
Claim 8
Dependent Claim
32 words
The method of claim 6 including the step of transmitting to the point of origin information derived from the step of comparing the signals with the signals in the data storage means.
Claim 9
Dependent Claim
28 words
The method of claim 1 wherein the signals derived are those representing each time a discrete one of said outputs is at least equal to said predetermined value.
Claim 10
Dependent Claim
20 words
The method of claim 8 wherein said last-mentioned step comprises the step of providing a visual indication of said signals.
Claim 11
Dependent Claim
16 words
The method of claim 9 wherein said last-mentioned step comprises the step of recording said signals.
Claim 12
Dependent Claim
24 words
The method of claim 8 wherein said last-mentioned step comprises the step of counting the number of said signals occurring in discrete time intervals.
Claim 13
Dependent Claim
48 words
The method of claim 8 including the step of comparing said signals with statistically valid groups of similar signals in a data storage means to ascertain the degree of correspondence of said signals with any one or more of said groups of signals in the data storage means.
Claim 14
Dependent Claim
33 words
The method of claim 12 wherein said step of comparing said signals with said groups of signals in the data storage means including the step of transmitting said signals to a remote location.
Claim 15
Dependent Claim
32 words
The method of claim 13 including the step of transmitting to the point of origin information derived from the step of comparing the signalS with the signals in the data storage means.
