  Patent No. 4889526   Non-invasive method and apparatus for modulating brain signals through an external magnetic or electric field to reduce pain (Rauscher, et al., Dec 26, 1989) Abstract This invention incorporates the discovery of new principles which utilize magnetic and electric fields generated by time varying square wave currents of precise repetition, width, shape and magnitude to move through coils and cutaneously applied conductive electrodes in order to stimulate the nervous system and reduce pain in humans. Timer means, adjustment means, and means to deliver current to the coils and conductive electrodes are described, as well as a theoretical model of the process. The invention incorporates the concept of two cyclic expanding an collapsing magnetic fields which generate precise wave forms in conjunction with each other to create a beat frequency which in turn causes the ion flow in the nervous system of the human body

  Patent No. 4335710   Device for the induction of specific brain wave patterns (Williamson, Jun 22, 1982) Abstract Brain wave patterns associated with relaxed and meditative states in a subject are gradually induced without deleterious chemical or neurological side effects. A white noise generator (11) has the spectral noise density of its output signal modulated in a manner similar to the brain wave patterns by a switching transistor (18) within a spectrum modulator (12). The modulated white noise signal is amplified by output amplifier (13) and converted to an audio signal by acoustic transducer (14). Ramp generator (16) gradually increases the voltage received by and resultant output frequency of voltage controlled oscillator (17) whereby switching transistor (18) periodically shunts the high frequency components of the white noise signal to ground. Notes: TECHNICAL FIELD The present invention relates generally to a

  Patent No. 4315502   Learning-Relaxation device (Gorges, Feb 16, 1982) Abstract Disclosed is a device for relaxing, stimulating and/or driving brain wave form function in a human subject. The device comprises, in combination, an eye mask having independently controlled left and right eyepieces and a peripheral light array in each eyepiece, an audio headset having independently controlled left and right earpieces and a control panel which controls light and sound signals to the light arrays and earpieces, respectively. Various control functions allow simultaneous or alternating light and sound pulsations in the left and right light arrays and earpieces, as well as selective phasing between light and sound pulsations. Notes: BACKGROUND OF THE INVENTION This invention relates to the art of learning and relaxation aids and more particularly to a device which releases psychological and physiological stress and tension prima

  Patent No. 3893450   Method and apparatus for brain waveform examination (Ertl, Oct9, 1973) Abstract A method and apparatus for examining the brain waveform of a subject, for example in a type of electro-encephalography (EEG), by providing a stimuli, such as a light, and determining a characteristic of a mathematically determinable point in the brain waveforms of the subject. A number of brain waveforms are obtained after successive stimuli and where the mathematically determinable point is the zero crossing point, the time intervals to the second and third falling zero crossings in the brain waveform are considered to provide average values which are identified as the "A score" and the "B score" respectively and are utilized to indicate the condition of the subject. A closed loop feedback path may be used for stimulation of the subject.   Notes:   BACKGROUND AND NATURE OF THE INVENTION This inv
