Flexible headset for sensing brain electrical activity
First Claim
Patent Images
1. A device for detecting brain electrical activity of a subject, the device comprising:
- a base unit; and
a headset that communicates with the base unit, the headset including;
a flexible band having a first end, a second end, and a center portion;
a first and a second securing device respectively adjacent to the first and second ends of the flexible band;
wherein the band includes a first expansible region between the first end and the center portion, and a second expansible region between the second end and the center portion, and wherein the first and the second expansible regions are configured to adaptively stretch or contract to accommodate different forehead sizes when the first and the second securing devices are anchored to the subject'"'"'s ears;
flexible circuitry in the band, the flexible circuitry including at least one sensor; and
a stimulus emitter coupled to the band; and
further wherein the headset is configured to automatically place the at least one sensor in an accurate position on the forehead when the first and the second securing devices are anchored to the subject'"'"'s ears.

Abstract
A headset for detecting brain electrical activity is disclosed. The headset may have a flexible band having a first end and a second end. The flexible band may have at least one expansible region permitting a distance between the first end and the second end to selectably vary. The headset may also have flexible circuitry in the flexible band. The flexible circuitry may be operatively connected to at least one sensor configured to sense brain electrical activity. The headset may further have a stimulus emitter coupled to the flexible band.

11. A headset for detecting brain electrical activity of a patient, comprising:
-
a flexible band having a first end, a second end, and a center portion; a first sensor coupled to the center portion and configured to sense brain electrical signals; a second sensor coupled adjacent to one of the first end or the second end and configured to sense brain electrical signals; and securing devices located at the first end and the second end; and flexible circuitry in the flexible band, the flexible circuitry operatively connected to the first and second sensor; wherein the flexible band includes a first expansible region adjacent to the first end and a second expansible region adjacent to the second end permitting a distance between the first end and the second end to selectably vary with respect to the center portion; and further wherein the flexible band is configured to automatically place the second sensor in an accurate position on the forehead of the patient, without any manual adjustment of the first expansible region or the second expansible region, by locating the securing devices behind the patient'"'"'s ears. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
