Abstract: In at least one embodiment, a sleep inhibiting device comprises a plurality of ring-like, metallic contacting devices worn on adjacent fingers of a human hand. The contacting devices close an electrical circuit when brought into mutual contact as a result of the adjacent fingers being brought into a contiguous relationship. The sleep inhibiting device may also comprise means for physically attracting the ring-like devices to each other, thereby requiring a wearer to consciously apply a countering force to prevent physical contact of the ring-like devices. Upon inadvertent relaxation of the muscles of the hand and fingers of a wearer, the ring-like devices are brought into contact with each other and thereby close a circuit that activates a stimulation means, such as a buzzer, and thereby awakens the wearer. In one embodiment of this invention, the ring-like devices are magnetized and oppositely poled to increase the likelihood of contact upon relaxation of the muscles of the fingers and hand.
