Abstract

Example devices are disclosed herein that include a first elongated band coupled to a first housing to be located on a first side of a head of a subject and a second housing to be located near a second side of the head of the subject, the first elongated band comprising a first set of electrodes. The example device also includes a second elongated band coupled to the first housing and to the second housing, the second elongated band comprising a second set of electrodes. In addition, the device includes a third elongated band coupled to the first housing and to the second housing, the third elongated band comprising a third set of electrodes.

First claim

What is claimed is:

1. A method comprising:
obtaining first neuro-response data from a subject with a device oriented in a first direction relative to the subject, the device including:
a first band including a first set of electrodes; and
a second band including a second set of electrodes; and

obtaining second neuro-response data from the subject with the device oriented in a second direction relative to the subject, the second direction substantially orthogonal to the first direction.

2. The method of claim 1 , wherein the first band has a first end and a second end, the second band has a third end and a fourth end, the first end is coupled to the third end, and the second end is coupled to the fourth end.

3. The method of claim 2 , wherein the first end is coupled to the third end through a first housing and the second end is coupled to the fourth end through a second housing.

4. The method of claim 3 further including analyzing, by executing an instruction with a processor disposed in the second housing, the first neuro-response data and the second neuro-response data.

5. The method of claim 4 , wherein the first housing includes an adjustment mechanism to adjust a fit of the device on the subject.

6. The method of claim 4 , further including determining, by executing instruction with the processor, a mental state of the subject.

7. The method of claim 6 , further including transmitting, with a transmitter disposed in the second housing, at least one of the mental state, the first neuro-response data, or second neuro-response data.

8. The method of claim 4 , further including amplifying, via an amplifier disposed in the second housing, at least one of the first neuro-response data or the second neuro-response data.

9. The method of claim 3 , wherein, when the device is oriented in the first direction, the first housing is disposed near a first ear of the subject and the second housing is disposed near a second ear of the subject and, when the device is oriented in the second direction, the first housing is disposed on a forehead of the subject and the second housing is disposed on a back of a head of the subject.

10. The method of claim 3 , wherein the first band and the second band are rotatably coupled to the first housing and the second housing.

11. The method of claim 3 , wherein the first band and the second band are removably coupled to the first housing and the second housing.

12. The method of claim 1 further including gathering a midline reading from a brain of the subject with the device oriented in the second direction.

13. The method of claim 1 , wherein the first direction is side-to-side and the second direction is front-to-back.

14. The method of claim 1 , further including independently adjusting a position of the first band and the second band.

15. The method of claim 1 , further including, after obtaining the first neuro-response data, rotating the device on a head of the subject.

16. The method of claim 1 , wherein the first neuro-response data and the second neuro-response data include electroencephalographic data.

17. The method of claim 1 , wherein the first band includes a first adjustable elastic band to a change a first distance between the first band and a head of the subject and the second band includes a second adjustable elastic band to change a second distance between the second band and the head of the subject.

18. The method of claim 1 , wherein the first band includes a plurality of extensions and the electrodes of the first set are individually disposed at respective ends of the extensions.

19. The method of claim 18 , wherein the extensions are flexible.

20. The method of claim 1 , wherein at least one of the electrodes of the first set includes at least one of a portion of a ring, a ball, or a hook.
