System and method for detecting whether a person is under the influence of a psychotropic substance
First Claim
1. A system for determining whether an equipment operator is under the influence of a psychotropic substance, said system comprising:
- input means for receiving signals from a subject regarding the frequencies of the subject'"'"'s brain waves, and for producing raw sample data;
processing means for processing said raw sample data, and for producing evaluation data responsive to said raw sample data and responsive to pre-recorded threshold data, said evaluation data being indicative of whether said raw sample data includes a signal having a frequency within the range of about 14 Hz to about 40 Hz; and
control means for providing a pass/fail signal responsive to the evaluation data to be used to control equipment.

Abstract
A system is disclosed for determining whether an equipment operator is under the influence of a psychotropic substance. The system includes an input unit for receiving signals from the subject regarding the frequencies of the subject'"'"'s brain waves, and for producing raw sample data. The system also includes a processing unit for processing the raw sample data, and for producing evaluation data responsive to the raw sample data and responsive to pre-recorded threshold data. The system also includes a control unit for providing a pass/fail signal responsive to the evaluation data to be used to control equipment.

8. A system for determining whether an equipment operator is under the influence of a psychotropic substance, said system comprising:
-
electrode sensors for receiving brain wave signals from a subject regarding the frequencies of the subject'"'"'s brain waves, and for producing a set of raw sample data;
an evaluation unit for determining a fail count based on the set of raw sample data, and for producing evaluation data representative of said fail count, said evaluation data being indicative of whether said brain wave signals from a subject include a signal having a frequency within the range of about 14 Hz to about 40 Hz; and
control means for providing a pass/fail signal responsive to the evaluation data to be used to control equipment. - View Dependent Claims (9)

10. A system for determining whether an equipment operator is under the influence of a psychotropic substance, said system comprising:
-
electrode sensors for receiving brain wave signals from a subject regarding the frequencies of the subject'"'"'s brain waves, and for producing a set of three raw sample data points;
cycling means for obtaining a plurality of sets of three raw sample data points;
an evaluation unit for determining a fail count based on the plurality of sets of raw sample data, and for producing evaluation data representative of said fail count, said evaluation data being indicative of whether said raw sample data includes a signal having a frequency within the range of about 14 Hz to about 40 Hz; and
control means for providing a pass/fail signal responsive to the evaluation data to be used to control equipment.
