Enhanced electrode headset
First Claim
1. An electrode assembly for detecting brain waves in the form of electric impulses, said assembly comprising:
- a. Electrode containing means including a cylindrical wall, a top cover and a bottom cover defining a hollow container, said bottom cover including an aperture therein;
b. A hollow rod mounted in said container and extending from said aperture in said bottom cover, said hollow rod having upper and lower openings;
c. an electrode element reciprocally received in said lower opening of said hollow rod;
d. signal amplification means located in said hollow rod between said electrode element and said upper opening;
e. a source of power positioned between said signal amplification means and said electrode element in said hollow rod and coupled to said signal amplification means for driving said signal amplification means;
f. means between said electrode element and said signal amplification means for biasing said electrode element away from said signal amplification means, said biasing means subject to being overcome upon said electrode element being driven into said hollow rod, for turning on said amplification means; and
,g. means responsive to pressure for partially driving said hollow rod out of said container and through said aperture for effecting contact of said electrode element with the scalp of an subject and for overcoming said biasing means for turning on said signal amplification means.

Abstract
An electrode assembly is mounted in a helmet like headset for use in making multiple electrode contact with the scalp. Each electrode assembly includes an electrode that floats in a cylinder mounted in a pressure responsive drive, which, when under pressure carries the electrode toward the scalp of a patient wearing the headset. Mounted in the cylinder above the electrode and biased away from the electrode is an LSI chip carrying an operation amplifier and a power supply for the amplifier. When the electrode makes contact with the scalp the cylinder continues to drive forward. Back pressure from contact with the scalp overcomes the bias and completes a circuit to turn on the amplifier. The amplifier is connected via wire or a wireless signal transmit system to a computer into which amplified signals are fed.
