Abstract
Abstract A SELF-PROPELLED MOTORIZED TOY WHOSE MOVEMENT IS CONTROLLED BY THE DISTANCE BETWEEN IT AND ANOTHER OBJECT, SUCH AS A HUMAN OPERATOR. A TRANSISTOR OSCILLATOR, RESONANT TANK CIRCUIT, CAPACITIVE DEVICE WHOSE CAPACITANCE IS DETERMINED BY THE DISTANCE BETWEEN IT AND THE OBJECT CONNECTED TO THE RESONANT TANK CIRCUIT, AND A TRANSISTORIZED AMPLIFIER ARE CONNECTED TOGETHER IN SUCH A MANNER THAT THE INCREASE OR DECREASE IN CAPACITANCE OF THE CAPACITIVE DEVICE CAUSES A DECREASE OR INCREASE IN THE INPUT SIGNAL APPLIED TO THE AMLIFIER. THE AMPLIFIER IS CONNECTED TO A RELAY SWITCH WHICH IN A FIRST STATE DIRECTS CURRENT FROM A POWER SOURCE TO A MOTOR WHICH OPERATES TO MOVE THE TOY, AND IN A SECOND STATE, DIRECTS CURRENT TO OTHER MEANS WHICH OPERATE OTHER MOVEMENTS OF OTHER PARTS OF THE TOY, SUCH AS FLAPS AND WHISTLES.
