Physics of Sound and Vibration: Effects On Human Electro-Dynamic Physiology

  Patent No. 4573449   Method for stimulating the falling asleep and/or relaxing behavior of a person and an arrangement therefor (Warnke, Mar 4, 1986) Abstract A method and apparatus is provided with which a person suffering from sleeplessness can be more easily relaxed and may more rapidly fall asleep. In particular, sound pulses are emitted by an electro-acoustic transducer, according to the cadence of which, the person seeking to fall asleep is induced to breathe in and out over a predetermined period of time. By suitably selecting the pulse sequence frequency, the pitch and the amplitude of the sound pulses may be adjusted thereby enhancing the process of falling asleep. Notes: BACKGROUND OF THE INVENTION The invention relates to a method for stimulating falling asleep and/or relaxing behavior of a person by means of an electronic arrangement. From numerous medical publications as well as from daily life, it

  Patent No. 4354505   Method of and apparatus for testing and indicating relaxation state of a human subject (Shiga, Oct 19, 1982) Abstract In a self-training biofeedback system, a physiological signal representing the state of relaxation of a person using the system is applied to a time counter to generate a binary count output representing the relaxation period. A visual indicator connected to the time counter provides the self trained person with a quick display of the measured time period so he can gauge the depth of his relaxation. Notes:   BACKGROUND OF THE INVENTION The present invention relates to self-training biofeedback systems for indicating the mental condition of a person to assist him in bringing his mind into a state of relaxation. It is well known that human mental activity can be measured in terms of electrical activity of the brain as represented by the brain waves, or in terms of electrical

  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
