Abstract
In an alarm system for gaining the attention of an individual requiring neither sound nor light for its operation, a transmitter unit is activated to send a signal at a predetermined frequency into an induction loop to be received by a receiver unit worn on the person of the individual whose attention it is intended to gain. The transmitter unit sends its signal for at least a predetermined period and the receiver unit responds by activating a mechanical agitator of selectable frequency and amplitude to cause bodily displacement of the receiver unit in a cyclic, periodic manner.
