Patent No. 6527696 Wave generation apparatus (Kim, Mar 4, 2003)
Abstract
An alpha wave generation apparatus has a voltage controller including a first resistor connected in parallel to an adapter jack and a battery, a converter for supplying power to a microcomputer, a first coil and a diode connected in series between the first resistor and an input terminal of the converter, a second resistor for maintaining an input voltage to the microcomputer constant in level, and a capacitor being charged with an input voltage to the converter or discharging it. The alpha wave generation apparatus generates alpha waves of 4 Hz, 8 Hz, and 10 Hz which, for example, may be used to activate cerebral cells.
Notes:
SUMMARY
OF THE INVENTION
Therefore, the present invention has been made in view of the above problems,
and it is an object of the present invention to provide an alpha wave generation
apparatus for generating alpha waves of 4 Hz, 8 Hz and 10 Hz capable of activating
cerebral cells and applying them to a cerebrum to stimulate it and thus activate
its cells, thereby improving a person's studying effect and concentration, getting
rid of his stress, lending him assistance to the promotion in his health, clearing
up his insomnia, improving the competitiveness of athletes and enhancing the
intellectual power of children of little intelligence as much as possible.
It should be noted that the present alpha wave generation apparatus is applicable
to all industrial fields desiring the alpha waves as well as the above-mentioned
object.
In accordance with the present invention, the above and other objects can be
accomplished by a provision of an alpha wave generation apparatus comprising
voltage control means including a first resistor connected in parallel to an
adapter jack and a battery, a converter for supplying power to a microcomputer,
a first coil and a first diode connected in series between the first resistor
and an input terminal of the converter, a second resistor for maintaining an
input voltage to the microcomputer constant in level, and a first capacitor
being charged with an input voltage to the converter or discharging it; function
control means including an ON/OFF switch, a grade DOWN switch, a grade UP switch
and a function switch; display means for providing a visual indication of the
present operation state to the user; the microcomputer for controlling the entire
system operation and performing an analog/digital conversion function, a pulse
width modulation function and a digital/analog conversion function; frequency
generation means including frequency oscillation means for performing a frequency
oscillating operation in response to a control signal from the microcomputer,
and reset means for resetting the system when an abnormal state occurs in the
system, the reset means including a plurality of third resistors, a second capacitor
and a first transistor; and output means including amplification means for amplifying
an output frequency signal from the frequency generation means and outputting
the amplified signal through a second coil, and analog output means for outputting
a control signal to the amplification means in response to an output signal
from the function control means, the analog output means including a second
transistor turned on in response to a function selected by the function switch,
and a transformer having a primary coil for receiving an output voltage from
the voltage control means via a bias resistor when the second transistor is
turned on and a secondary coil for inducing a voltage at a predetermined turn
ratio relative to the primary coil, the amplification means including a third
transistor for receiving the voltage induced in the secondary coil of the transformer
in the analog output means via a second diode and outputting a frequency signal
corresponding to the received voltage to the second coil in response to the
control signal from the analog output means.
