Proximity responsive toy
First Claim
1. A toy having motor-driven drive means for propelling the same,electrical sensing circuit means on said toy, including a capacitor plate means for sensing the proximity of said toy to a capacitive body;
- and control circuit means responsive to a predetermined change in capacitance of said sensing circuit means upon close proximity of said capacitive body to said capacitor plate means for initiating operation of said motor for a predetermined period of time;
said drive means being arranged to drive said toy in a forward direction, said capacitor plate means including a plate positioned in a rear region of said toy whereby approach of a capacitive body to said rear region will cause said toy to move in a direction away therefrom; and
p1 a further plate positioned in a forward region of said toy whereby approach of a capacitive body thereto will cause said toy to move toward said latter capacitive body and follow any forward movement thereof.

Abstract
A wheel-supported figure toy in the form of a pup has a driving motor to propel it in a forward direction. Proximity sensors in the form of capacitor plates control operation of the motor. When a child'"'"'s hand or the like approaches the rear of the figure, the capacitance of a first capacitor arrangement is changed and the motor is started and propels the figure forwardly for a predetermined time, then stops. If the hand is placed under the pup'"'"'s chin, a second capacitor arrangement causes the pup to follow the hand. An RC network determines the time the motor is in operation by holding a monostable vibrator on, which keeps the motor running, after it is started, for the predetermined time interval. The toy also has a sounding device that operates when the figure is being propelled.
