Filed:

Jul 21, 1999

Appl. No.:

9/357959

Inventors:

David B. Hunter - King of Prussia PA

Assignee:

Capita Research Group Inc. - Blue Bell PA

International Classification:

A61B 504

US Classification:

600544

Abstract:

A system to integrate and synchronize a plurality of signals for recording on a destination video recording device and/or for display on a monitor. The plurality of signals represent the response of a respective of a plurality of test subjects to certain stimuli. A plurality of test subjects view an audio-visual display from an audio-video source, such as a video cassette recorder, while respective EEG responses to the audio-video display are measured. The respective EEG responses are sent to respective processors and converted to graphical representations of the EEG signals. The graphical representations of the EEG signals and a signal from the source audio-video device are sent to respective destination VCRs and/or a respective destination audio-video recording device that records the data from both sources. The respective destination audio-video recording devices can send respective composite signals to a respective destination VCR and/or a respective destination monitor to record and/or display the synchronized signals from the source audio-video recording device and the graphical representation of the EEG signals simultaneously. The respective destination VCRs and respective destination monitors can also record and/or display output and control data such as the time and date of the test.
