ABSTRACT:
An electronic system for awakening especially deaf persons and for relaxing and soothing tired and aching muscles of persons who frequently develop body tiredness from overwork or due to some organic illness is described. The systems comprises an electric timer unit for setting a desired time of the day when a sleeper intends to be awakened, and a pulsative resonator unit connected to said timer unit through an electric cord and is positioned, during use thereof, under the sleeper's pillow. When the set time of the day arrives, the timer unit automatically triggers the pulsative resonator unit, which causes a repeated vibratory action under the pillow and awakens the sleeper. The system is provided with a double-throw switch within a dual electric circuit therein whereby the repeatedly occurring vibratory pulsations produced in one of the circuits therein can be altered to one of continuous vibratory pulsations for application in the means for relaxing of tired or aching bodily muscles and thereby soothing the body.
