1. An electrode unit comprising:
- a guide having a first opening;
an electrode disposed in the first opening, the electrode movable in the first opening, the electrode having a body, a first spring, and a pin, the pin biased outward from a first end of the body via the first spring;
a second spring disposed over the first opening and engaged with a second end of the body;
a connector having a second opening, the guide disposed in the second opening, the connector to removably couple the electrode unit to a band to be disposed over a head of a subject, the connector being electrically conductive, the second spring in contact with the connector such that an electrical signal obtained by the electrode is transferred through the second spring and through the connector to the band; and
an electrode unit housing having a third opening, the connector disposed in the third opening.

Abstract
Example headsets and electrodes are described herein. Example electrode units described herein include a guide defining an opening and an electrode disposed in the opening. The electrode has a housing, a spring, and a pin. The pin is biased outward from a first end of the housing via the first spring. The example electrode units also include a second spring disposed over the opening adjacent a second end of the housing.

19. An electrode unit comprising:
-
a connector having an opening; a guide disposed in the opening of the connector, the guide having a first end, a second end opposite the first end, and a passage extending between a first opening in the first end and a second opening in the second end; an electrode movably disposed in the passage, the electrode having a body, a first spring, and a pin, the pin biased outward from an end of the body via the first spring; and a spiral spring plate disposed over the opening of the connector and the first opening of the guide, an outer rim of the spiral spring plate in contact with the connector, the body of the electrode engaged with the spiral spring plate such that the spiral spring plate biases the electrode outward from the second opening in the second end of the guide, the spiral spring plate movable between an unbiased state in which the second spring is substantially flat and a biased state in which a center of the spiral spring plate flexes away from the guide and the connector while the outer rim of the spiral spring plate remains in contact with the connector. - View Dependent Claims (20)
