Appeal No. 96-2635
Application 07/993,050
producing a binary control signal by changing between
(a) and (b).
21. Method of producing a communication or control
signal by an unaided person, comprising:
monitoring the mu wave from the brain of the person;
determining whether the mu wave is above or below a
single threshold value, wherein values above the threshold
correspond to the person at rest, when the person is neither
moving nor thinking of moving a body part of the person, and
values below the threshold correspond to movement, when the
person is either moving or thinking of moving a body part of the
person;
producing changes above and below the single threshold
value by alternating between (a) neither moving nor thinking of
moving a body part of the person and (b) either moving or
thinking of moving a body part of the person,
producing a binary communication or control signal from
the changes of the mu wave above and below the threshold value.
