Electronic wand

Abstract

A wand adapted to be held in the hand and provided with a rod-like body provided with a handle having a base at one end and a visual indicator at the opposite end. The base defines a handle for grasping the wand and the base is hollow to house an electronic circuit and a battery for operating the circuit. The circuit is a multivibrator whose output signal oscillates at a given frequency, such as 120 Hz. The visual indicator is coupled with the circuit and is caused to flash at the operating frequency of the circuit when the circuit operates. The base has a pair of spaced terminals thereon which are bridged by the palm of the hand when the base is grasped, and the palm therefore provides a resistance forming part of the circuit to cause the frequency of flashing of the visual indicator to change depending upon the extent to which hand pressure is applied to the base. For increased frequency, greater hand pressure is applied to decrease the resistance accordingly. Conversely, by decreasing the hand pressure the frequency will decrease.
