Abstract: An apparatus and method to induce sleep in a patient that utilizes an oscillator to control the frequency of electric impulses received by the patient. First and second multivibrators generate the signals necessary to stimulate the central nervous system by conduction through the optic nerve tract, and also to generate a visual aura caused by stimulation of the retina of the eye. An amplifier amplifies the signals generated by the multivibrators and electrodes transmit the amplified signal to the patient. The various components of the apparatus may be stored in an eye frame structure wherein eye lid electrode pads are held in place contiguous the eyes of the patient, and wherein mastoid electrode pads are held in place by means of the frame ear hooks.

Abstract: The invention comprises a hand-held bat to be used in any game of the player's choosing in which a ball, shuttlecock or the like is batted back and forth among two or more players.
