MEDICAL APPARATUS FOR COLLECTING PATIENT ELECTROENCEPHALOGRAM (EEG) DATA
First Claim
1. An EEG Processing Unit for collecting EEG sensor data from a subject for forwarding to a data processing system, comprising:
- a plurality of EEG sensors, responsive to the presence of EEG signals for generating electrical signals representative of said EEG signals;
frame having said plurality of EEG sensors mounted thereon in predetermined locations, for placement on a Patient'"'"'s head thereby to site each of said plurality of EEG sensors at a corresponding predetermined location on a surface of the Patient'"'"'s head to detect said EEG signals; and
signal processor, mounted on said frame, for processing said electrical signals representative of said EEG signals to remove artifacts therefrom.

Abstract
The EEG Processing Unit comprises a semi-rigid framework which substantially conforms to the Patient'"'"'s head and supports a set of electrodes in predetermined loci on the Patient'"'"'s head to ensure proper electrode placement. The EEG Processing Unit includes automated connectivity determination apparatus which can use pressure-sensitive electrode placement ensuring proper contact with Patient'"'"'s scalp and also automatically verifies electrode placement via measurements of electrode impedance through automated impedance checking. Voltages generated by the electrodes are amplified and filtered before being transmitted to an analysis platform, which can be a Physician'"'"'s laptop computer system, either wirelessly or via a set of tethering wires. The EEG Processing Unit includes an automatic artifacting capability which identifies when there is sufficient clean data compiled in the testing session. This process automatically eliminates muscle- or other physical-artifact-related voltages. Clean data, which represents real brain voltages as opposed to muscle- or physical-artifact-related voltages, thereby are produced.
