Abstract
Abstract A manikin synchronization system is described to cause recorded aural sounds to be coincident with mechanical motions including the effects of the breathing cycles. The synchronization system interfaces with the mechanical and audio systems in order to bring heart sounds, breathing cycles and mechanical motions into time coincidence. The synchronizing system accepts pulses from a mechanical master timing shaft which indicates the mid-points of the breathing cycles. These pulses are applied to the synchronization system which, in response to additional synchronization information on an audio tape, indicates whether the audio signal is early or late with respect to the mechanical system. Accordingly, a voltage controlled oscillator produces an output proportional to the indication to control the tape drive and create synchronization of the audio and mechanical systems.
