摘要

The device has heat variable tracers arranged in series in a receiver, where the tracers are provided with information and are reciprocatably effected by frequency or amplitude modulation using an electronic controller. The tracers are movable in all spatial axes. Actuators are provided to control a position, frequency, and time of the individual tracer or the tracer group in the receiver.
