ABSTRACT:
A recording device which utilizes a closed loop servo system including a limited rotation motor, i.e. a moving coil galvanometer wherein the moving coil is activated by an input signal such that the rotational movement of a shaft supporting such coil may be translated into a graphic display for recording of the input signal. The device has specific utility in the recording of medical information wherein the input signal is created by the patient's body functions but has widespread alternate utility. The device further includes a transducer construction utilizing a rotational resistance mechanism including a rotating hub to which a contact arm is attached that creates a signal proportional to the position of the coil shaft and utilizes this signal for comparison with the input signal such that the coil position and thus that of the shaft may be corrected. Any mechanical or electrical vibration in the resistance element is prevented or reduced by the use of a viscous dampening material disposed between the hub and contact arm of the rotational resistance mechanism.
