Patent ID: 7386347

Claim:
An electric stimulator for alpha-wave derivation comprising: a control section including: a key input unit for supporting user operation; a microprocessor for setting a frequency, a voltage, a cycle and an operation time according to a key input signal transferred from the key input unit, for controlling an output of the frequency and voltage according to the set data, for determining whether the outputted frequency and voltage are applied to an ear of a user, for performing a switching of a wire/wireless mode by determining whether a jack is connected to an electric stimulating unit, for outputting a transmitting signal to wirelessly transmit a setting data after a predetermined time, when the wireless mode is switched, and for outputting a turn-on/off signal corresponding to an alarm signal and the turn-on/off signal indicative of a wire/wireless mode control state; a control-side transmitter/receiver for transmitting the setting data according to the transmitting signal and transmitting/receiving input/output data; an oscillator for oscillating at a frequency of 1 Hz to 50 Hz according to a frequency output control; and a connector connected to the jack and connected to the microprocessor for determining the wire/wireless state according to variations of input current value; a connecting line connecting the connector with the jack and transferring the frequency and voltage from the jack to the electric stimulating unit; and the electric stimulating unit including: a contacting terminal connected to the connecting line and adapted to contact an auricle of vagus nerves of the ear; a wire/wireless detecting unit interposed between the connecting line and the contacting terminal for detecting the wire/wireless mode state according to whether it is connected to the jack or not; a remote control unit for determining the wire/wireless mode state, for controlling operation of the electric stimulating unit itself, in the case of the wireless mode, and for controlling the frequency and voltage according to the set data transmitted from the control-side transmitter/receiver; a transmitter/receiver communicating with the control-side transmitter/receiver for transmitting the input/output data to the remote control unit; an oscillator for supplying the frequency to the remote control unit; and a battery for supplying an electric power to the remote control unit.
