## Abstract

Example apparatus and methods for gathering electroencephalographic signals are disclosed herein. An example apparatus includes a band to be worn on a head of a person and a first strip adjustably coupled to the band. The example apparatus also includes a first set of electrodes coupled to the first strip to gather a first set of signals from the head and a magnetic fastener to couple the first strip to the band.

## Claims

### Claim 1

A method comprising:
adjusting a first strip relative to a band worn on a head of a person using a magnetic fastener by sliding a first magnetic element to a first position on the band;
coupling a second magnetic element coupled to the first strip to the first magnetic element to join the first strip and the band; and
gathering a first set of signals from the head using a first set of electrodes coupled to the first strip.

### Claim 2 (depends on 1)

The method of claim 1, further including sliding the first strip relative to a support coupled to the band.

### Claim 3 (depends on 1)

The method of claim 1, further including:
adjusting a second strip relative to the band; and
gathering a second set of signals from the head using a second set of electrodes coupled to the second strip.

### Claim 4 (depends on 3)

The method of claim 3, further including independently adjusting the first strip and the second strip relative to the band.

### Claim 5 (depends on 1)

The method of claim 1, further including communicatively coupling a first reference electrode to a processor.

### Claim 6 (depends on 5)

The method of claim 5, further including coupling a first connector of a first terminal to which the first reference electrode is coupled to the processor to communicatively couple the first reference electrode and the processor.

### Claim 7 (depends on 6)

The method of claim 6, further including magnetically coupling the first connector of the first terminal to the processor.

### Claim 8 (depends on 1)

The method of claim 1, wherein the adjusting includes changing an effective length of the first strip.

### Claim 9

An apparatus comprising:
a headband to be worn around a head of a person;
a first strip to be disposed over the head of the person;
a first set of electrodes coupled to the first strip to gather a first set of signals from the head of the person; and
a fastener to couple the first strip to the headband, the fastener including:
a first connector coupled to and slidable along the headband; and
a second connector coupled to the first strip, the second connector removably couplable to the first connector to couple the first strip to the headband.

### Claim 10 (depends on 9)

The apparatus of claim 9, wherein the first connector includes an aperture to receive the headband.

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein the first connector includes a protrusion that extends into the aperture to engage the headband.

### Claim 12 (depends on 11)

The apparatus of claim 11, wherein the protrusion includes a leaf spring.

### Claim 13 (depends on 9)

The apparatus of claim 9, wherein the first connector includes a first magnetic element and the second connector includes a second magnetic element, the second magnetic element to magnetically couple to the first magnetic element to couple the first connector to the second connector.

### Claim 14 (depends on 13)

The apparatus of claim 13, wherein one of the first magnetic element or the second magnetic element includes a metal plate and the other of the first magnetic element or the second magnetic element includes a magnet.

### Claim 15 (depends on 9)

The apparatus of claim 9, wherein the first strip is coupled to the second connector via a strap extending through an opening in the second connector.
