METHOD OF AND APPARATUS FOR DETECTING LIVING BODIES

摘要

A process and device are disclosed for sensing living bodies, in particular for sensing living human bodies, by means of electromagnetic signals and a receiver for electromagnetic signals. The detection of vital functions allows persons buried alive to be found and survivors to be distinguished from corpses, thus saving precious time. The invention is also suitable for monitoring buildings or for sensing patient vital functions. The receiver (3) for electromagnetic signals has a device for extracting the frequency components characteristic of living bodies from the electromagnetic signals.
