ABSTRACT:
A device for testing and improving manual and mental dexterity includes a series of lamps and switches finger transferrable between open and closed states. A network interconnects the switches and lamps with a current source, so that the actuation of the switches in a predetermined sequence to closed and opened states within a predetermined time energizes all the lamps and maintains them energized. The network includes first and third similar transistors and a third transistor of opposite type. The base of the first transistor is connected by a capacitor to the junction of a switch and lamp series connected across the voltage supply, the collector of the second transistor is grounded through a large capacitor and the base of the third transistor is connected through a capacitor and resistor to its emitter by way of one of the switches.
