Apparatus, Systems and Method for Receiving Signals from a Human Subject's Brain
First Claim
1. Apparatus for use in connection with receiving electroencephalographic (EEG) signals from a human subject'"'"'s head through the scalp thereof, the apparatus comprising:
- a removable headset arranged and adapted to extend at least partially around the subject'"'"'s head over at least part of the subject'"'"'s scalp, said headset including an inner side and an outer side, said inner side being closest to the subject'"'"'s scalp when said headset is positioned least partially around the subject'"'"'s head,said headset including a plurality of electrode stations and a plurality of intermediate portions extending between said electrode stations and shaped and sized to form open spaces therebetween, each said electrode station having an electrode aperture extending therethrough from said outer side to said inner side of said headset and a biasing flap coupled to said outer side of said headset and at least partially aligned over said associated electrode aperture, said headset further including at least one EEG signal transmission wire associated with said electrode stations for receiving EEG signals;
a plurality of removable electrodes releasably engageable with said headset and useful to facilitate the transmission of EEG signals from the subject'"'"'s head to at least one said EEG signal transmission wire of said headset during use of said headset, each said electrode including a top end, bottom end and at least one side extending therebetween, wherein each said electrode is configured to be releasably suspended within one of said electrode apertures and biased between said headset and the subject'"'"'s head by said associated biasing flap; and
a plurality of electrode covers constructed at least partially of flexible, liquid-absorbing material and arranged and adapted to be electrically-conductive, receive EEG signals from the subject'"'"'s head and transmit such signals to at least one said EEG signal transmission wire of said headset during use of said headset, each said electrode cover at least partially encapsulating one said electrode and being laden with electrically-conductive liquid during use of said headset,wherein said each biasing flap is configured to at least partially sandwich said associated electrode cover between said associated electrode and the subject'"'"'s head and into contact with the subject'"'"'s head to receive EEG signals from the subject'"'"'s head and transmit such signals to at least one said EEG signal transmission wire of said headset during use of said headset.

Abstract
Apparatus for use in connection with receiving signals from a human subject'"'"'s head through the scalp thereof includes a removable headset having a plurality of electrode stations and intermediate portions. Each electrode station includes an electrode aperture extending therethrough and a biasing flap coupled to the outer side of the headset and at least partially aligned over the associated electrode aperture. A plurality of removable electrodes is releasably engageable with the headset and configured to be releasably suspended within the electrode apertures and biased between the headset and the subject'"'"'s head by the associated biasing flaps.

27. A method of receiving useful signals from a human subject'"'"'s head through the scalp thereof with the use of a removable headset arranged and adapted to extend at least partially around the subject'"'"'s head over at least part of the subject'"'"'s scalp, the headset including an inner side and an outer side, the inner side being closest to the subject'"'"'s scalp when the headset is positioned least partially around the subject'"'"'s head, the method comprising:
