Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A headband for sensing human physiological characteristics and the like, comprising: an elongated strip of adherent material having a hook surface and a loop surface on opposite sides thereof, said strip being of a length sufficient to encircle the head of the wearer, at least one electrode of adherent material having a hook surface and a loop surface on opposite sides thereof, at least one spacer of adherent material having a hook surface and a loop surface on opposite sides thereof, one of said hook surface and said loop surface of the electrode being plated with an electrically conductive material, the other of said hook surface and said loop surface of the electrode being pressed against the mating one of the hook surface and the loop surface of said spacer, the other of said hook surface and said loop surface of the spacer being pressed against the mating one of the hook surface and the loop surface of said strip and being shiftable along the length of said strip, and means for electrically interconnecting said plated surface of said electrode with a measuring and a correlating system.
Claim 2
Dependent Claim
187 words
