Abstract
Abstract A mask adapted to be worn on the head of a person includes more than two electrodes adapted to couple electrical pulse signals to provide parallel current paths from a pulse source to the head of the person to induce sleep or relaxation. Flexible members couple the signals to different surfaces of the person''s head. Adjustment means are associated with at least one of the flexible elements to vary the state of compression thereof and thereby balance the current paths between the two current paths provided by the two electrodes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
147 words
In combination with a source of electrical pulse signals, a mask adapted to be worn on the head of a person, first and second pairs electrodes connected to said source to provide a pair of parallel current paths, said first and second pairs of electrodes being secured to said mask, flexible coupling elements in contact with said first pair of electrodes to provide coupling from said electrodes to the front surfaces of the head of said person, said flexible elements having conductive fluid therein, adjustable means in physical engagement with at least one of the flexible elements in one of said parallel current paths to permit said one flexible element to be adjusted to vary the state of compression of said flexible element on the head of said person and the amount of current flowing through the path including said one flexible element engaging said adjustment means.
Claim 2
Dependent Claim
147 words
In combination with a source of electrical pulse signals, a mask adapted to be worn on the head of a person, first and second pairs electrodes connected to said source to provide a pair of parallel current paths, said first and second pairs of electrodes being secured to said mask, flexible coupling elements in contact with said first pair of electrodes to provide coupling from said electrodes to the front surfaces of the head of said person, said flexible elements having conductive fluid therein, adjustable means in physical engagement with at least one of the flexible elements in one of said parallel current paths to permit said one flexible element to be adjusted to vary the state of compression of said flexible element on the head of said person and the amount of current flowing through the path including said one flexible element engaging said adjustment means.
Claim 3
Dependent Claim
62 words
The invention as set forth in claim 1 wherein said adjustment means includes a knob, a backup plate secured to said mask and having threaded connecting means in engagement with said one flexible element, a threaded shaft connected between said knob and said backup plate to enable a person to turn said knob to manually compress or expand said one flexible element.
Claim 4
Dependent Claim
67 words
The invention as set forth in claim 2 wherein said mask is adapted to fit around the head of said person with said first pair of electrodes disposed to contact the eyelids of said person with said flexible elements between said first pair of electrodes and said eyelids, with said adjustment means Being connected to said first pair of electrodes to permit manual adjustment by said person.
Claim 5
Dependent Claim
38 words
The invention as set forth in claim 3 wherein one of said pairs of electrodes are provided to contact the rear of the head of said person to provide a return path to said source of electrical signals.
