COMPUTER-AIDED DRUG-ABUSE DETECTION

摘要

The invention contemplates computer-aided analysis of recorded electronystagmograph data for a subject who is suspected of drug ingestion. The reference base for the analysis is predetermined by first entering into computer storage digital data that are characteristic of each of a selected plurality of component features of time-varying fluctuations in electronystamograph waveforms for each of a plurality of different ingested drugs, wherein the selected component features exist within a standardized set of at-rest conditions of electronystagmograph measurements. The plurality of component features is selected such that each of the drugs is characteristically identifiable by the presence of its singular combination of said component features. The subject's time-varying fluctuations in electronystagmograph waveforms are non-invasively measured and digitally recorded, for each of the at-rest conditions of the standardized set; and the subject's digitally recorded waveform is compared with the digitally stored reference data for each of the component features to ascertain the existence vel non of any correlation therebetween, thereby enabling determination as to whether a particular drug-identifying combination of the component features exists.
